Table, computed property and vuex data - vuejs2

I'm in need of help with computed properties .. it's hard to explain but I'll try ..
I have a table with filter and pagination that I created.
When I pass the data directly from a request the API works,
but when I have to work with data coming from vuex I'm having trouble ...
Because I do not know when the data will be filled in vuex
And then I use the computed property because the moment the vuex is filled it will capture the data ..
However as the function that fills the data is the same one that is executed when I click on the page I crash the process and the page stops working.
Below is the computed property:
list(){
if (this.url_get == '' && this.$store.state.table.list.length > 0){
this.total_data = this.$store.state.table.list.length
this.repos = this.$store.state.table.list
this.getPaginatedItems(1)
}
var filter = this.configs.filter.toString().toLowerCase()
var items = ''
if (filter == ''){
items = this.dados
}else{
items = this.repos
}
const list = this.$lodash.orderBy(items, this.configs.orderBy, this.configs.order)
this.reverse = 1;
if (this.$lodash.isEmpty(filter)) {
return list;
}
var result = this.$lodash.filter(list, repo => {
return repo[this.filter_term].toString().toLowerCase().indexOf(filter) >= 0
})
return result
},
And the function:
getPaginatedItems(data) {
var items = this.repos
var page = data
var per_page = 10
var offset = (page - 1) * per_page
var max_item = offset+per_page
var paginatedItems = this.$lodash.slice(items, offset, max_item)
var obj = {
offset: offset,
current_page: page,
per_page: per_page,
total: items.length,
total_pages: Math.ceil(items.length / per_page),
data: paginatedItems,
last: offset+paginatedItems.length,
max_item: max_item
}
this.pagination = obj
this.dados = this.pagination.data
},
Request who fill the data in vuex
axios
.get(`api/getusuariosgrupo/${id}`)
.then(res => {
if (res.data.dados !== undefined && res.data.dados.length !== 0){
vmThis.isEditing = true
var d = {
list: res.data.dados,
length: res.data.dados.length
}
this.$store.commit('SET_TABLE', d)
}else{
vmThis.isEditing = false
}
vmThis.$bus.$emit('processando',{val: false})
})

How to add new fileds/values to line widgets in Barcode mobile view in Odoo14 EE?

Hi i am trying to add two new fields to the Barcode mobile view. I went through the default js code of odoo, but didn't find a way to add my custome fields to it.
Here is the default code
stock_barcode/static/src/js/client_action/lines_widget.js
init: function (parent, page, pageIndex, nbPages) {
this._super.apply(this, arguments);
this.page = page; #don't know where this argument page coming from in argument list.
this.pageIndex = pageIndex;
this.nbPages = nbPages;
this.mode = parent.mode;
this.groups = parent.groups;
this.model = parent.actionParams.model;
this.show_entire_packs = parent.show_entire_packs;
this.displayControlButtons = this.nbPages > 0 && parent._isControlButtonsEnabled();
this.displayOptionalButtons = parent._isOptionalButtonsEnabled();
this.isPickingRelated = parent._isPickingRelated();
this.isImmediatePicking = parent.isImmediatePicking ? true : false;
this.sourceLocations = parent.sourceLocations;
this.destinationLocations = parent.destinationLocations;
// detect if touchscreen (more complicated than one would expect due to browser differences...)
this.istouchSupported = 'ontouchend' in document ||
'ontouchstart' in document ||
'ontouchstart' in window ||
navigator.maxTouchPoints > 0 ||
navigator.msMaxTouchPoints > 0;
},
In _renderLines function,
_renderLines: function () {
//Skipped some codes here
// Render and append the lines, if any.
var $body = this.$el.filter('.o_barcode_lines');
console.log('this model',this.model);
if (this.page.lines.length) {
var $lines = $(QWeb.render('stock_barcode_lines_template', {
lines: this.getProductLines(this.page.lines),
packageLines: this.getPackageLines(this.page.lines),
model: this.model,
groups: this.groups,
isPickingRelated: this.isPickingRelated,
istouchSupported: this.istouchSupported,
}));
$body.prepend($lines);
for (const line of $lines) {
if (line.dataset) {
this._updateIncrementButtons($(line));
}
}
$lines.on('click', '.o_edit', this._onClickEditLine.bind(this));
$lines.on('click', '.o_package_content', this._onClickTruckLine.bind(this));
}
In the above code, you can see this.page.lines field, i need to add my custom two more fields.
Actually it's dead-end for me.
Any solution?

Is there a way to wait until a function is finished in React Native?

I'm trying to get information (true/false) from AsyncStorage in a function and create a string which is importent to fetch data in the next step. My problem is, the function is not finished until the string is required.
I tried many solutions from the internet like async function and await getItem or .done() or .then(), but none worked out for me.
//_getFetchData()
AsyncStorage.getAllKeys().then((result) => { //get all stored Keys
valuelength = result.length;
if (valuelength !== 0) {
for (let i = 0; i < valuelength; i++) {
if (result[i].includes("not") == false) { //get Keys without not
AsyncStorage.getItem(result[i]).then((resultvalue) => {
if (resultvalue === 'true') {
if (this.state.firstValue) {
this.state.channels = this.state.channels + "channel_id" + result[i];
console.log("channel: " + this.state.channels);
}
else {
this.state.channels = this.state.channels + "channel" + result[i];
}
}
});
}
return this.state.channels;
_fetchData() {
var channel = this._getFetchData();
console.log("channel required: " + channel);
}
The current behaviour is that the console displays first "channel required: " than "channel: channel_id0".
Aspects in your question are unclear:
You don't say when this.state.firstValue is set, and how that relates to what you are trying to accomplish.
You have a for-loop where you could be setting the same value multiple times.
You mutate the state rather than set it. This is not good, see this SO question for more on that.
There are somethings we can do to make your code easier to understand. Below I will show a possible refactor. Explaining what I am doing at each step. I am using async/await because it can lead to much tidier and easier to read code, rather than using promises where you can get lost in callbacks.
Get all the keys from AsyncStorage
Make sure that there is a value for all the keys.
Filter the keys so that we only include the ones that do not contain the string 'not'.
Use a Promise.all, this part is important as it basically gets all the values for each of the keys that we just found and puts them into an array called items
Each object in the items array has a key and a value property.
We then filter the items so that only the ones with a item.value === 'true' remain.
We then filter the items so that only the ones with a item.value !== 'true' remain. (this may be optional it is really dependent on what you want to do)
What do we return? You need to add that part.
Here is the refactor:
_getFetchData = async () => {
let allKeys = await AsyncStorage.getAllKeys(); // 1
if (allKeys.length) { // 2
let filteredKeys = allKeys.filter(key => !key.includes('not')); // 3
let items = await Promise.all(filteredKeys.map(async key => { // 4
let value = await AsyncStorage.getItem(key);
return { key, value }; // 5
}))
let filteredTrueItems = items.filter(item => items.value === 'true'); // 6
let filteredFalseItems = items.filter(item => items.value !== 'true'); // 7
// now you have two arrays one with the items that have the true values
// and one with the items that have the false values
// at this points you can decide what to return as it is not
// that clear from your question
// return the value that your want // 8
} else {
// return your default value if there are no keys // 8
}
}
You would call this function as follows:
_fetchData = async () => {
let channel = await this._getFetchData();
console.log("channel required: " + channel);
}
Although the above will work, it will not currently return a value as you haven't made it clear which value you wish to return. I would suggest you build upon the code that I have written here and update it so that it returns the values that you want.
Further reading
For further reading I would suggest these awesome articles by Michael Chan that discuss state
https://medium.learnreact.com/setstate-is-asynchronous-52ead919a3f0
https://medium.learnreact.com/setstate-takes-a-callback-1f71ad5d2296
https://medium.learnreact.com/setstate-takes-a-function-56eb940f84b6
I would also suggest taking some time to read up about async/await and promises
https://medium.com/#bluepnume/learn-about-promises-before-you-start-using-async-await-eb148164a9c8
And finally this article and SO question on Promise.all are quite good
https://www.taniarascia.com/promise-all-with-async-await/
Using async/await with a forEach loop
Try this instead. Async functions and Promises can be tricky to get right and can be difficult to debug but you're on the right track.
async _getFetchData() {
let channels = "";
let results = await AsyncStorage.getAllKeys();
results.forEach((result) => {
if (result.includes("not") === false) {
let item = await AsyncStorage.getItem(result);
if (item === 'true') {
console.log(`channel: ${result}`)
channels = `channel_id ${result}`;
}
}
});
return channels;
}
_fetchData() {
this._getFetchData().then((channels) => {
console.log(`channel required: ${channel}`);
});
}
what if you wrap the _getFetchData() in a Promise? This would enable you to use
var channel = this._getFetchData().then(console.log("channel required: " + channel));
Otherwise the console.log won't wait for the execution of the _getFetchData().
This is what the console.log is telling you. it just logs the string. the variable is added after the async operation is done.
UPDATE
I would try this:
//_getFetchData()
AsyncStorage.getAllKeys().then((result) => { //get all stored Keys
valuelength = result.length;
if (valuelength !== 0) {
for (let i = 0; i < valuelength; i++) {
if (result[i].includes("not") == false) { //get Keys without not
AsyncStorage.getItem(result[i]).then((resultvalue) => {
if (resultvalue === 'true') {
if (this.state.firstValue) {
this.state.channels = this.state.channels + "channel_id" + result[i];
console.log("channel: " + this.state.channels);
}
else {
this.state.channels = this.state.channels + "channel" + result[i];
}
}
});
}
return new Promise((resolve, reject) => {
this.state.channels !=== undefined ? resolve(this.state.channels) : reject(Error('error '));
}
_fetchData() {
var channel = this._getFetchData().then(console.log("channel required: " + channel));
}
maybe you must change the this.state.channels !=== undefined to an expression that's matches the default value of this.state.channels.

Sensenet Content Picker Customization

I created two custom content types, ProjectContract and PaymentRequest. Under PaymentRequest, I have a reference field Contract which I would like to use to reference ProjectContract. When I am creating/changing PaymentRequest, I need the following:
how can I initialize Content Picker to display ContractNumber field of available ProjectContracts?
how can I display selected ProjectContract's ContractNumber under ReferenceField Grid control?
The SN js code and the mvc contains/returns fix field values. I did not find any setting where I can add custom fields to show.
First of all, what is the version of that SN package, because the oData.svc request will not work on older versions. It is available from 6.2.
About the oData, here is a link: http://wiki.sensenet.com/OData_REST_API
There is another way to solve it, but with this, you need to modify the existion SN codes.
You need to copy (" /Root/Global/scripts/sn/SN.Picker.js ") file into your skin folder with the same structure. (" /Root/Skins/[yourskinfolder]/scripts/sn/SN.ReferenceGrid.js ")
You need to copy (" /Root/Global/scripts/sn/SN.ReferenceGrid.js ") file into your skin folder as well.
Do not modify the original SN file, because it will be overwrite after an SN update.
Next step: copy the following code to line 1068, before the ("$grid.jqGrid({") line, into the InitGrid function.
...
var neededTypeName = "ProjectContract";
var neededFieldName = "ContractNumber";
var findField = false;
o2 = (function () {
var result = [];
var itemArray = [];
$.each(o2, function (index, el) {
el.ContentField = "";
result.push(el);
if (el.ContentTypeName == neededTypeName) {
itemArray.push([index, el.Path]);
findField = true;
}
});
if (findField) {
$.each(itemArray, function (itemIndex, itemElArray) {
var itemId = itemElArray[0];
var itemEl = itemElArray[1];
var thisLength = itemEl.length;
var thislastSplash = itemEl.lastIndexOf("/");
var thisPath = itemEl.substring(0, thislastSplash) + "('" + itemEl.substring(thislastSplash + 1, thisLength) + "')";
$.ajax({
url: "/oData.svc" + thisPath + "?metadata=no$select=Path," + neededFieldName,
dataType: "json",
async: false,
success: function (d) {
result[itemId].ContentField = d.d[neededFieldName];
}
});
});
colNames.splice(6, 0, "ContentField");
colModel.splice(6, 0, { index: "ContentField", name: "ContentField", width: 100 });
return result;
}
return o2;
})();
...
$grid.jqGrid({
...
The "neededTypeName" may contains your content type value, and the "neededFieldName" may contains the field name you want to render.
The other will build up the grid.
This will modify the Content picker table.
You need to add this code into the GetResultDataFromRow function, at line 660 before the return of the function.
...
if (rowdata.ContentField != undefined) {
result.ContentField = rowdata.ContentField;
}
...
This will add the selected item properties from the Content picker to the reference field table.
Then you need to open the SN.ReferenceGrid.js and add the following code into the init function before the "var $grid = $("#" + displayAreaId);"
var neededTypeName = "CustomItem2";
var neededFieldName = "Custom2Num";
var findField = false;
var alreadyAdded = false;
var btnAttr = $("#"+addButtonId).attr("onClick");
if (btnAttr.indexOf(neededTypeName) > -1) {
alreadyAdded = true;
colNames[4].width = 150;
colModel[4].width = 150;
colNames.splice(3, 0, "ContentField");
colModel.splice(3, 0, { index: "ContentField", name: "ContentField", width: 60 });
}
initialSelection = (function () {
var result = [];
var itemArray = [];
$.each(initialSelection, function (index, el) {
el.ContentField = "";
result.push(el);
if (el.ContentTypeName == neededTypeName) {
itemArray.push([index, el.Path]);
findField = true;
}
});
if (findField) {
$.each(itemArray, function (itemIndex, itemElArray) {
var itemId = itemElArray[0];
var itemEl = itemElArray[1];
var thisLength = itemEl.length;
var thislastSplash = itemEl.lastIndexOf("/");
var thisPath = itemEl.substring(0, thislastSplash) + "('" + itemEl.substring(thislastSplash + 1, thisLength) + "')";
$.ajax({
url: "/oData.svc" + thisPath + "?metadata=no$select=Path," + neededFieldName,
dataType: "json",
async: false,
success: function (d) {
result[itemId].ContentField = d.d[neededFieldName];
}
});
});
if (!alreadyAdded) {
colNames.splice(3, 0, "ContentField");
colModel.splice(3, 0, { index: "ContentField", name: "ContentField", width: 100 });
}
return result;
}
return initialSelection;
})();
I hope this will help but the SN version should be helpful.

Saving data from XMLHttpRequest Response to my IndexedDB

I have created a json file containing my Sql Server datas. With the XmlHttpRequest's GET method, I am reading json file and iterating and saving those records to my IndexedDB.. Everything is working fine.. After the end of the iteration, I wrote a code to alert the user.. But the alert message is displayed very quickly, but when I see it in the console window, the saving operation is till processing.. I want to alert the user, only after the operation is completed..
My code is,
if (window.XMLHttpRequest) {
var sFileText;
var sPath = "IDBFiles/Reservation.json";
//console.log(sPath);
var xhr = new XMLHttpRequest();
xhr.open("GET", sPath, 1);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200) {
if (xhr.responseText != "") {
sFileText = xhr.responseText;
//console.log(sFileText);
var val = JSON.parse(sFileText);
var i = 0;
var value = val.length;
for(var i in val)
{
var code = val[i].RTM_res_category_code;
var desc = val[i].RTM_res_category_edesc;
addReserv(code, desc);
}
if(i >= value-1) {
console.log("Reservation Load Completed... "+i);
document.getElementById("status").innerHTML = "Reservation Loading Success...";
}
}
}
}
xhr.send();
}
//Passing Parameters to Reservation
function addReserv(code, desc)
{
document.querySelector("#status").innerHTML = "Loading Reservation.. Please wait...";
var trans = db.transaction(["Reservation"], "readwrite");
var store = trans.objectStore("Reservation");
//console.log(store);
var reserv={ RTM_res_category_code : code, RTM_res_category_edesc : ''+desc+'' };
var request = store.add(reserv);
request.onerror = function(e) {
console.log(e.target.error.name);
document.querySelector("#status").innerHTML = e.target.error.name;
}
request.onsuccess = function(e) {
console.log("Reservation Saved Successfully.");
//document.querySelector("#status").innerHTML = "Reservation Loaded Successfully.";
}
}
Thanks for the question.
What you are currently doing works, but the alert comes to soon because of the async nature of the IDB.
What you should to avoid this.
1. Create your transaction only once.
2. Do all your operations in this one transaction.
3. The transaction object has an oncomplete callback you can use to notify the user.
Concrete on your example. Instead of looping over the items in the ajax callback, pass the collection to your add method and loop there
if (window.XMLHttpRequest) {
var sFileText;
var sPath = "IDBFiles/Reservation.json";
//console.log(sPath);
var xhr = new XMLHttpRequest();
xhr.open("GET", sPath, 1);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && xhr.status == 200) {
if (xhr.responseText != "") {
sFileText = xhr.responseText;
//console.log(sFileText);
var val = JSON.parse(sFileText);
import(val);
}
}
}
xhr.send();
}
function import(values)
{
document.querySelector("#status").innerHTML = "Loading Reservation.. Please wait...";
var trans = db.transaction(["Reservation"], "readwrite");
var store = trans.objectStore("Reservation");
var i = 0;
var value = val.length;
for(var i in val)
{
var code = val[i].RTM_res_category_code;
var desc = val[i].RTM_res_category_edesc;
var reserv={ RTM_res_category_code : code, RTM_res_category_edesc : ''+desc+'' };
var request = store.add(reserv);
request.onerror = function(e) {
console.log(e.target.error.name);
document.querySelector("#status").innerHTML = e.target.error.name;
}
request.onsuccess = function(e) {
console.log("Reservation Saved Successfully.");
//document.querySelector("#status").innerHTML = "Reservation Loaded Successfully.";
}
}
trans.oncomplete = function () {
console.log("Reservation Load Completed... "+i);
document.getElementById("status").innerHTML = "Reservation Loading Success...";
}
}

Extjs, define scope of column's renderer function

I think that, bydefault renderer always refer to its calling object as scope. and we do not have to define anything but in my grid i have different behaviour.
I have to define rendere function runtime.
I make column object and for each column i assign renderer.
for (var i = 0; i < columns.length; i++) {
newRenderer = function (v, m, r, rI, cI, s)
{
if(this.originalRend) <<<<<-----------------
// "this" is not object of column but whole page.
{
//then call original}
else {
// call new renderer
}
}
columns[i].originalRend = columns[i].renderer;
columns[i].renderer = newRenderer;
}
In my newRenderer function "THIS" does not refer to column object. WHY?????
and how to do that????
You should be able to use scope as a config option of the column, and that will be used by the renderer:
{
renderer: function(val){
return val.trim();
},
scope: this
}
Or, in the case of your code:
for (var i = 0; i < columns.length; i++) {
newRenderer = function (v, m, r, rI, cI, s)
{
if(this.originalRend) <<<<<-----------------
// "this" is not object of column but whole page.
{
//then call original}
else {
// call new renderer
}
}
//THIS LINE ADDED:
columns[i].scope = columns[i];
columns[i].originalRend = columns[i].renderer;
columns[i].renderer = newRenderer;
}
See docs here: http://docs.sencha.com/extjs/4.1.3/#!/api/Ext.grid.column.Column-cfg-scope
Scope does not work as column or this.
The best way is to overrite prepareData method of header container.
Ext.override(Ext.grid.header.Container, {

dirtyCls = me.dirtyCls,
colIdx = 0,
header,
headerId,
renderer,
value,
metaData,
store = panel.store;
for (; colIdx < headersLn; colIdx++) {
metaData = {
tdCls: '',
style: ''
};
header = headers[colIdx];
headerId = header.id;
renderer = header.renderer;
value = data[header.dataIndex];
if (typeof renderer == "function") {
value = renderer.call(
//--------change made below.------------------
header.scope || header || me.ownerCt,
//----------------end-------------------------
value,
// metadata per cell passing an obj by reference so that
// it can be manipulated inside the renderer
metaData,
record,
rowIdx,
colIdx,
store,
view
);
}
// <debug>
if (metaData.css) {
// This warning attribute is used by the compat layer
obj.cssWarning = true;
metaData.tdCls = metaData.css;
delete metaData.css;
}
// </debug>
if (me.markDirty) {
obj[headerId + '-modified'] = record.isModified(header.dataIndex) ? dirtyCls : '';
}
obj[headerId+'-tdCls'] = metaData.tdCls;
obj[headerId+'-tdAttr'] = metaData.tdAttr;
obj[headerId+'-style'] = metaData.style;
if (typeof value === 'undefined' || value === null || value === '') {
value = header.emptyCellText;
}
obj[headerId] = value;
}
return obj;
},
}
