The JSONP proxy is largely working for me, but I need to set properties of a model based on some nested properties in the JSON response. I can't figure how to do this without extending the Reader class, but thought there might be an easier way that I'm just missing.
My Recipe model:
Ext.define('NC.model.Recipe', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'name', type: 'string' },
{ name: 'image', type: 'string' },
{ name: 'preparationText', type: 'string' },
{ name: 'ingredientsText', type: 'string' },
{ name: 'servings', type: 'string' }
]
}
});
My Store:
Ext.define('NC.store.Recipes', {
extend: 'Ext.data.Store',
config: {
model: 'NC.model.Recipe',
storeId: 'Recipes',
proxy: {
type: 'jsonp',
url: 'http://anExternalSite.com/api',
callbackKey: 'callback',
filterParam: 'text',
extraParams: {
type: 'Recipe'
},
reader: {
type: 'json',
idProperty: 'uuid',
}
}
}
});
The JSON format:
[
{
uuid: "/UUID(XXXX)/",
name: "Spicy Peanut Noodle Salad",
image: "http://someplace.com/noodle-salad.jpg",
properties: {
preparationText: "Make it all nice and stuff",
ingredientsText: "Heaps of fresh food",
servings: "serves 4",
}
},
{ ... },
{ ... }
]
I would like those 3 'properties' - preparationText, ingredientsText, and servings, to be placed in the model, but currently only id, name, and image are. What is the method to make this work? If it does involve extending the Reader class, some direction would be great.
Thanks.
You can change your code like this to access nested values
{ name: 'preparationText', type: 'string', mapping: 'properties.preparationText' },
This mapping path should start excluding the root element.

This is my model
Ext.define("StockWatch.model.Market", {
extend: "Ext.data.Model",
config: {
idProperty: 'CompanyCode',
fields: [
{ name: 'CompanyCode', type: 'string' },
{ name: 'LastTradedPrice', type: 'string' },
{ name: 'PercentageDiff', type: 'string' },
{ name: 'FiftyTwoWeekHigh', type: 'string' },
{ name: 'FiftyTwoWeekLow', type: 'string' },
{ name: 'ChangePercent', type: 'string' },
{ name: 'Change', type: 'string' },
{ name: 'MarketCap', type: 'string' },
{ name: 'High', type: 'string' },
{ name: 'Low', type: 'string' },
{ name: 'PrevClose', type: 'string' },
{ name: 'OpenInterest', type: 'string' },
{ name: 'MarketLot', type: 'string' },
{ name: 'ChangeInOpenInterest', type: 'string' },
{ name: 'LastTradedTime', type: 'date', dateFormat: 'c' },
]
}
});
this is my store
Ext.define("StockWatch.store.Markets", {
extend: "Ext.data.Store",
requires: ["Ext.data.proxy.LocalStorage", "Ext.data.proxy.JsonP", "StockWatch.model.Market"],
config: {
model: "StockWatch.model.Market",
autoLoad : true,
proxy : {
type : 'jsonp',
url : 'http://money.rediff.com/money1/current_status_new.php?companylist=17023928%7C17023929&id=1354690151&Rand=0.6305125835351646',
reader:{
type:'json',
rootProperty:''
}
}
}
});
I'm not able to get the data on to my list, may be somewhere fetching of data is wrong.
guide me to find the solution.
also I'm using pull to refresh list plugin, so will the data be loaded automatically each time i pull down the list or do i have to write something over there to??
thnx in advance
EDIT:
I also get this warning in the console
Resource interpreted as Script but transferred with MIME type text/html: "http://money.rediff.com/money1/current_status_new.php?companylist=17023928%7C17023929&id=1354690151&Rand=0.6305125835351646&_dc=1355822361093&page=1&start=0&limit=25&callback=Ext.data.JsonP.callback1".
use callbackKey
callbackKey: Specifies the GET parameter that will be sent to the server containing the function name to be executed when the request completes. Defaults to callback. Thus, a common request will be in the form of url?callback=Ext.data.JsonP.callback1
Defaults to: "callback"
You need to wrap the JSON response in a callback function for JSONP. It doesn't look like your remote call is returning this, try specifying a callback parameter - otherwise if the remote server does not allow this you need to pass it through another server to wrap it in a callback function.
Also, the warning you mentioned in the bottom of your post, don't worry about that. It won't cause any problems.
I have a list reading from a Json store which contains a grouper on a field of type int. This field is called "req" in the sample model below. However, rather than group by the int value, I would like to assign a text value instead, so for example, in case of "1" I would group by "Yes" and in case of "0" I would group by "No". The conversion can be hard coded as it will not change. Where do I make this conversion in my code? Thanks for your help
Ext.define('MyApp.store.MyStore', {
extend: 'Ext.data.Store',
requires: [
'MyApp.model.MyData'
],
config: {
model: 'MyApp.model.MyData',
storeId: 'MyStore',
proxy: {
type: 'ajax',
url: '/path/to/data.json',
reader: {
type: 'json',
rootProperty: 'items'
}
},
grouper: {
property: 'req',
sortProperty: 'req'
},
groupDir: 'DESC'
}
});
Model:
Ext.define('Mypp.model.MyModel', {
extend: 'Ext.data.Model',
config: {
fields: [
{
name: 'example',
type: 'string'
},
{
name: 'req',
type: 'int'
}
]
}
});
Add to the Model a calculated field with convert() function:
Ext.define('Mypp.model.MyModel', {
extend: 'Ext.data.Model',
config: {
fields: [
{
name: 'example',
type: 'string'
},
{
name: 'req',
type: 'int'
},
{
name: 'reqDisplay',
type: 'string',
convert: function (value, record) {
if (value == null) {
var req = record.get('req');
value = req ? 'Yes' : 'No'
}
return value;
}
}
]
}
});
... and use it instead
grouper: {
property: 'reqDisplay',
sortProperty: 'reqDisplay'
},
Cheers, Oleg
I have a combobox, i need to populate data from the server. In the server side i have the following data to be displayed.
PersonID
PersonFName
PersonLName
In the combobox, i need to display the text as PersonFName + PersonLName (Like James Smith- This is what it will display in the drop down) , and when a user selects a record, I need to display the corresponding PersonID (Like Person with PersonFName and PersonLName has the PersonID of 1) of that user.
I am unable to figure this out, here's my code
View :
{
xtype: 'combobox',
id: 'personcombo',
readOnly: false,
selectOnFocus: true,
forceSelection: true,
store: 'Person'
}
Store :
Ext.define('MyApp.store.PersonStore', {
extend: 'Ext.data.Store',
requires: [
'MyApp.model.Person'
],
constructor: function(cfg) {
var me = this;
cfg = cfg || {};
me.callParent([Ext.apply({
model: 'MyApp.model.Person',
proxy: {
type: 'ajax',
api: {
read: 'person.php',
create: 'person.php'
},
reader: {
type: 'array'
}
}
}, cfg)]);
}
});
Model :
Ext.define('MyApp.model.Person', {
extend: 'Ext.data.Model',
fields: [
{
name: 'PersonID'
},
{
name: 'PersonFName'
},
{
name: 'PersonLName'
}
]
});
I think your question is: how to display PersonFName + PersonLName in the combobox but keep the PersonID field as the value.
You should add a converted field which joins the first and last names in your data model and then make that one your combobox displayField config.
Though the other answer did bring up a good point that the defined store in your combo is Person but you are showing code for a store named PersonStore.
It would look something like this:
Model:
Ext.define('MyApp.model.Person', {
extend: 'Ext.data.Model',
fields: [
{
name: 'PersonID'
},
{
name: 'PersonFName'
},
{
name: 'PersonLName'
},
{
name: 'PersonName',
convert: function(value, record) {
return record.data.PersonFName + ' ' +
record.data.PersonLName;
}
}
]
});
Store:
// changed to "Person" instead of "PersonStore"
Ext.define('MyApp.store.Person', {
extend: 'Ext.data.Store',
requires: [
'MyApp.model.Person'
],
model: 'MyApp.model.Person',
proxy: {
type: 'ajax',
api: {
read: 'person.php',
create: 'person.php'
},
reader: 'array'
}
});
View:
{
xtype: 'combobox',
id: 'personcombo',
readOnly: false,
selectOnFocus: true,
forceSelection: true,
store: 'Person',
valueField: 'PersonID',
displayField: 'PersonName' // the converted field
}
Your combobox has 'Person' as the store, but I don't see you create a store called Person anywhere. Try store: Ext.create('MyApp.store.PersonStore', {autoLoad: true}).
You can also simplify your store:
Ext.define('MyApp.store.PersonStore', {
extend: 'Ext.data.Store',
requires: [
'MyApp.model.Person'
],
model: 'MyApp.model.Person',
proxy: {
type: 'ajax',
api: {
read: 'person.php',
create: 'person.php'
},
reader: 'array'
}
});
I have a model Banner and a model BannerFormat. A banner has a banner format. To configure a hasOne relationship between banner and banner format, i wrote this :
Ext.define('admin.model.Banner', {
extend: 'Ext.data.Model',
config: {
fields: [
{ name: 'id', type: 'int' },
{ name: 'banner_format_id', type: 'int' },
'code',
'active',
'start_at',
'end_at'
],
associations: { type: 'hasOne', model: 'admin.model.BannerFormat', getterName: 'getBannerFormat' },
proxy: {
type: 'ajax',
url: '/admin/api_query.php',
extraParams: {
table: 'content_banners',
type: 'GET'
}
}
}
});
And in my bannerFormat model:
Ext.define('admin.model.BannerFormat', {
extend: 'Ext.data.Model',
config: {
fields: ['id', 'format'],
associations: { type: 'hasMany', model: 'admin.model.Banner' },
proxy: {
type: 'ajax',
url: '/admin/api_query.php',
extraParams: {
table: 'content_banner_formats',
type: 'GET'
}
}
}
});
But when i call banner.getBannerFormat(), i got :
Uncaught TypeError: Object [object Object] has no method 'getBannerFormat'
What did i go wrong?
Are you creating a banner object and then making the call on it to retrieve the defined associations?
This should work for you:
var banner = Ext.create('admin.model.Banner', {
id: 100,
banner_format_id: 20,
code: 'ABC123',
active: true,
start_at: 1,
end_at: 5
});
banner.getBannerFormat();
Also, you don't need to specify a getterName for the association if you don't want. Sencha will auto-generate a getter function for the association, which follows the format: 'getModelName'. If you removed the getterName from your association, the getter function on the banner model would be the same as what you defined it as: 'getBannerFormat';
I have defined a model which I want to use twice but with a different url int he proxy (in fact only the id differs) But how can I manage this?
Ext.define('TesterModel', {
extend: 'Ext.data.Model',
autoLoad: false,
fields: [
{ name: 'prename', type: 'string' },
{ name: 'lastname', type: 'string' },
{ name: 'dept', type: 'string' },
{ name: 'rackName', type: 'string' },
{ name: 'rackIP' , vtype:'IPAddress'}],
proxy: {
type: 'ajax',
url: 'php/getData_db.php?id=',
reader: {
type: 'json',
messageProperty: 'message',
root: 'data',
}
},
constructor: function() {
UrlParams=document.URL.split("?");
if(UrlParams.length > 1) {
SingleUrlParams=Ext.Object.fromQueryString(UrlParams[1]);
this.proxy.url = this.proxy.url + SingleUrlParams.right;
console.log(this.proxy.url);
}
return this;
}});
Ext.ModelMgr.getModel('TesterModel').load(0, { // load user with ID of "0"
success: function(tester) {
var rightPanel=Ext.getCmp('rightTester');
rightPanel.loadRecord(tester); // when tester is loaded successfully, load the data into the form
}
});
I thought that the constructor will be done before loading, but nope, it is done after. It's weired to me.
Any hints, please?
(the main URL it's like: .../index.html?left=xx&right=yy )
so I want to fill up a panel on the left with the one id, and a panel on the right window side eith th right id.
Thanks!
Try .getProxy().url = "what/ever.php"
