When Rendering a XLSX recipe with data from mssql I get this error
Error occured - Error during rendering report: Cannot read property
'xl/worksheets/sheet1.xml' of undefined Stak - TypeError: Cannot read
property 'xl/worksheets/sheet1.xml' of undefined
at Object.add (evalmachine.:176:42)
at Object. (evalmachine.:406:17)
at Object.eval (eval at createFunctionContext
I have my linked script set up to load data. example:
var sql = require('mssql');
var config = {
"user": "jsreport",
"password": "password",
"server": "janblaha-PC\\SQLEXPRESS",
"database": "northwind"
}
function beforeRender(done) {
sql.connect(config).then(function() {
var req = new sql.Request();
return req.query('select count(*) as Count, ShipCountry from Orders group by ShipCountry').then(function(recordset) {
request.data = { countries: recordset };
done();
});
}).catch(done);
}
I can load data into pdf, html, and even html-xlsx with no error. I tried to use just a basic sheet that I can get to load without the script, shown below. I have also tried using the data in {{#each }} statement. I always get the same error. Wondering if anyone has tried to do this and/or if I need to load my data a different way.
{{#xlsxAdd "xl/worksheets/sheet1.xml" "worksheet.sheetData[0].row"}}
<row>
<c t="inlineStr"><is><t>Hello world</t></is></c>
<c><v>11</v></c>
</row>
{{/xlsxAdd}}
{{{xlsxPrint}}}
Received an answer on Github:
//old
request.data = { countries: recordset };
//new
Object.assign(request.data, { countries: recordset })
The recipe is passing some additional data to the templating engines
processing and you are overwriting them.

var deptTable = $('#team-table').DataTable( {
"ajax": "/cc/AjaxDashboard/getMyTeam",
"pageLength": 10,
"scrollY": "250px"
});
I have this. The JSON response is just [] as there's no data. I am getting:
Cannot read property 'length' of undefined
I thought [] was valid JSON as per https://jsonlint.com/ and it would show an empty message but I get an error instead
[] is indeed a valid JSON syntax for empty array. The reason you're getting the error is because the data returned from your AJAX doesn't match the DataTable's default expectation.
There are 3 ways you can use with the ajax option:
Give it a string as the AJAX source
Give it a configuration object
Give it a function
And by default, when the AJAX source is given, DataTables expects the returned data to be an array of items with the key data:
{
data: []
}
If your AJAX doesn't return this format, you will get that error. Here is the proof: https://jsfiddle.net/davidliang2008/s2xgof6t/22/
To fix it, you can override the returned format by setting dataSrc to an empty string, like this:
{
ajax: {
url: xxx,
dataSrc: ''
}
}

I am developing a react native application with apollo client and I need to have 2 screens:
Screen A: displays a list of profiles
Screen B: displays some filters which have to be applied to Screen A
So my idea was to use apollo client cache to save the state of the filters in screen B, and then come back to screen A and somehow refetch with the new filters applied.
Since there are a couple of filters that I need to send on each request to the server, I also was thinking about using an input type so I can send my filters in the form of an object instead of a list of comma-separated parameters.
So looking at the docs from apollo client, there is a section to manage the local stage. In there, I found a sub-section called Using #client fields as variables. Basically, this part tells you how to grab whatever filters were stored in the cache and send it as part of the query.
However, I always get the following error:
Invariant Violation: Missing selection set for an object of type ProfileParameters returned for query field profileParameters
some code:
This is how I initialized the cache-store, for now, it only contains page and pageSize but it will contain more parameters.
const cache = new InMemoryCache({
cacheRedirects: {
Query: {
profile: (_, {id}, {getCacheKey}) =>
getCacheKey({__typename: 'Profile', id: id}),
},
},
});
cache.writeData({
data: {
profileParameters: {
__typename: 'ProfileParameters',
page: 0,
pageSize: 25,
},
},
});
const client = new ApolloClient({
uri: 'http://192.168.1.102:3000/graphql',
cache: cache,
resolvers: {},
});
And this is the query component and the query:
const PROFILES_QUERY = gql`
query getFilteredProfiles($type: String, $parameters: ProfileParameters) {
profileParameters #client #export(as: "parameters")
profiles(type: $type, parameters: $parameters) {
id
name
termOfEntry
sport
sportPosition
gpa
avatarUrl
imageUrl
nationality
countryOfResidence
dateOfBirth
annualBudget
career
satScore
toeflScore
graduationDate
}
}
`;
<Query
query={PROFILES_QUERY}
variables={{
type: this.PROFILE_TYPE,
}}>
...
</Query>
There is a type variable that is being passed in the variables object. That comes from a local variable in the class.
Also, screen B does not exist yet, but the cache is being initialized and I want to read whatever is in there so I can send those filters to the server.
For some reason my filter is not working correctly. It was working fine a moment ago and then for some reason it stopped returning all of the templates and only started returning one of them.
Why might it be returning it twice but only giving me one?
I have the following code:
export async function testMe() {
const company_id = await AsyncStorage.getItem('company_id');
const device_db = new PouchDB(company_id, {});
device_db.query(function(doc, emit){
console.log(doc.type, doc._id, doc._rev);
if(doc.type == 'template') {
emit(doc._id, doc);
}
}).then((result) => {
console.log("Returned", result);
})
}
What is unexpectedly happening is this is what gets returned:
template template_1 18-5918af4c5370d9755d0bb8b6dcb21ea1
template template_2 19-8191dec49dfa8c1a2f03d752a193f09e
template template_3 39-74f3b82ce4a38a501810b5ff31efc593
undefined "dpbcab6843-2cdf-4d4c-87ae-286dcddaac22" "2-8f03f3127771dadd3c8f7beb3e827982"
undefined "dpdc6f6cd0-6c6d-4974-a166-b848a0217af4" "2-0eec1a8d925641aa8bf30e058e6515e7"
undefined "dpe1573a70-a281-4e15-a997-82d8bf8fabfa" "2-d3bbcb81344f61cc94459610695c6670"
template template_3 39-74f3b82ce4a38a501810b5ff31efc593
You can ignore the undefined, but what I am trying to show is look at what gets returned twice:
template template_3 39-74f3b82ce4a38a501810b5ff31efc593
In the Returned console.log(), this is the only thing that gets returned (the last template_3 piece of data, totally ignoring the other templates even though they are both type template):
{"total_rows":6,"offset":0,"rows":[{"key":"template_3","id":"template_3","value":{..}}]}
Edit
It's getting even weirder. I just opened template_2 and did a save (in Cloudant) and synced it with my device to update the _rev and now I get:
template template_1 18-5918af4c5370d9755d0bb8b6dcb21ea1
template template_2 20-c549fe868735ef0099b80f6668af611c
template template_3 39-74f3b82ce4a38a501810b5ff31efc593
undefined "dpbcab6843-2cdf-4d4c-87ae-286dcddaac22" "2-8f03f3127771dadd3c8f7beb3e827982"
undefined "dpdc6f6cd0-6c6d-4974-a166-b848a0217af4" "2-0eec1a8d925641aa8bf30e058e6515e7"
undefined "dpe1573a70-a281-4e15-a997-82d8bf8fabfa" "2-d3bbcb81344f61cc94459610695c6670"
template template_3 39-74f3b82ce4a38a501810b5ff31efc593
template template_2 20-c549fe868735ef0099b80f6668af611c
Which returns (leaving out template_3):
{"total_rows":6,"offset":0,"rows":[{"key":"template_2","id":"template_2","value":{..}}]}
Edit 2
I added:
.catch((err) => {
console.log(err);
})
And get this: {"status":409,"name":"conflict","message":"Document update conflict","error":true}
However, I do the following an all _conflict arrays are empty:
device_db.allDocs({conflicts: true})
.then((data) => {
for (let d of data.rows) {
console.log(d.doc._conflicts);
}
});
I believe temporary queries like this should have a key, otherwise the query would not know what documents you want to select. The example from the PouchDb docs is
db.query(function (doc, emit) {
emit(doc.name);
}, {key: 'foo'}).then(function (result) {
// found docs with name === 'foo'
}).catch(function (err) {
// handle any errors
});
so that documents with a "name" field equal to "foo" are returned by the query. In your query the key appears to be undefined. This might explain the odd results you are getting?
I am starting to lose my mind in debugging an application that I inherited from a fellow developer who is absent.
I have narrowed down the problem to the following place in code (php files are checked, Vue instances are initialised, there are no syntax errors).
This is my the component that gets initialised:
var RadniStol = Vue.component('radnistol', {
template: '#template-RadniStol',
data() {
return {
tableData: [],
requestData: {
sort: "ID",
order: "DESC"
}
}
},
methods: {
reloadTable: function (event) {
data = this.requestData;
this.$http.post('php/get/radni_stol.php', data).then(response => {
console.log(response.data.bodyText);
this.tableData = response.data.records;
});
},
.
.
.
The PHP file that gets called with the POST method is working correctly, querying the database and echoing the response in a JSON format.
The thing that is making me pull out my hair is the following: the console.log(response.data) outputs the following into the console:
{"records":[{"DODAN_NA_RADNI_STOL":"1","..."}]}
It is an JSON object that I expected to have but when trying to assign it to the data of the component with:
this.tableData = response.data;
or any other way… response.data.records returns ‘undefined’ in the console. I have tryed with JSON.parse() but no success.
When logging types to console:
response variable is a response object with a status 200 and body and bodyText containing the data from the database.
response.data is a string type containing the string JSON with the data from the database.
When trying to use JSON.parse(response.data) or JSON.parse() on anything in the callback of the POST method I get the following error in the console:
RadniStol.js?version=0.1.1:17 Uncaught (in promise) SyntaxError: Unexpected token in JSON at position 0
at JSON.parse (<anonymous>)
at VueComponent.$http.post.then.response (RadniStol.js?version=0.1.1:17)
at <anonymous>
I am really starting to lose my mind over this issue, please help!
Thank you
If response.data is string, with JSON inside, then to access the records field, you should decode it like this:
JSON.parse(response.data).records
Not sure this has something to do with PHP or Vue.js, it is just plain javascript issue.
If it not decodes, than problem is definitely in response.data. For example
{"records":[{"DODAN_NA_RADNI_STOL":"1","..."}]}
is not a valid JSON, because key "..." needs to have some value.
But it seems to me that response.data is already parsed.
What I suggest you to do, is to write handler of the response as separate function, make response object that mimics actual response object by hand, and then test it separately from request. So you could show us request object and function that works with it.
I had the same error and fixed it.
Result will be response.body not response.data.
Here is my code:
getS: function(page) {
this.$http.get('vue-manager?page=' + page).then((response) => {
var data = JSON.parse(response.body);
this.student = data.data.data;
this.pagination = data.pagination;
});
},
i want to check the returned value of $http.get() but i get undefined value. Here is my vue js code:
var vm = new Vue({
el: '#permissionMgt',
data: {
permissionID: []
},
methods:{
fetchPermissionDetail: function (id) {
this.$http.get('../api/getComplaintPermission/' + id, function (data) {
this.permissionID = data.permissionID; //permissionID is a data field of the database
alert(this.permissionID); //*****this alert is giving me undefined value
});
},
}
});
Can you tell me thats the problem here?.. btw $http.get() is properly fetching all the data.
You need to check what type is the data returned from the server. If #Raj's solution didn't resolve your issue then probably permissionID is not present in the data that is returned.
Do a colsole.log(data) and check whether data is an object or an array of objects.
Cheers!
Its a common js error. Make the following changes and it will work.
fetchPermissionDetail: function (id) {
var self = this; //add this line
this.$http.get('../api/getComplaintPermission/' + id, function (data) {
self.permissionID = data.permissionID; //replace "this" with "self"
});
},
}
the reason is this points to window inside the anonymous function function()
This is a well known js problem. If you are using es2015 you can use arrow syntax (() => { /*code*/ }) syntax which sets this correctly
