Checkbox does not Populate from Collection

I am caught in a web. I am unable to populate dropdown2. The code works until ‘label’: ‘Select Application’. I was wondering what to type under res.items.map. I have typed the collection name which is named Application.

import wixData from ‘wix-data’;

export function dropdown1_change_1(event, $w) {
wixData.query(‘Application’)
.eq(‘authorityid’, $w(“#dropdown1”).value)
.find()
.then(res => {
let options = [{
“value”: ‘’,
‘label’: ‘Select Application’
}];
options.push(…res.items.map(application => {
return {
‘value’: application.title,
‘label’: application.title
};
}));
$w(‘#dropdown2’).enable();
$w(‘#dropdown2’).options = options;
});
}

Hi Sunil,

Note the change in the following chunk of code:

return {
   'value': application,
   'label': application
};

You don’t say what doesn’t work, but I hope this helps,

Hi Yisrael,

But it made no impact. Still the same.

import wixData from ‘wix-data’;

export function dropdown1_change_1(event, $w) {
wixData.query(‘Application’)
.eq(‘authorityid’, $w(“#dropdown1”).value)
.find()
.then(res => {
let options = [{
“value”: ‘’,
‘label’: ‘Select Application’
}];
options.push(…res.items.map(application => {
return {
‘value’: application,
‘label’: application
};
}));
$w(‘#dropdown2’).enable();
$w(‘#dropdown2’).options = options;
});
}

The same what? I am unable to help if I don’t know what the problem is.

Thanks for trying to assist Yisrael. I definitely need your help :slight_smile:

Well, the dropdown2 does not populate from the collection. It just shows the ‘Select Application’ label

Maybe your database query didn’t return anything. You can add a console.log(res) statement inside the .then() function to see if anything was returned. Like this:

.then(res => {
    console.log(res);

You can then see what, if anything, the query returned.

This is what came up in the log
{“items”:[],“length”:0,“totalCount”:0,“query”:{“invalidArguments”:[],“filterTree”:{“$and”:[{“authorityid”:“Dept of Economic Development”}]},“provider”:{},“collectionName”:“Application”,“limitNumber”:50,“included”:[]}}

The query results are empty. Either your collection is empty, or your query is incorrect.

Thanks for the hint
The collection has data

Is there an issue using a reference field?
.eq(‘authorityid’, $w(" #dropdown1 ").value)

The authorityid used above is a reference field type

I realised the mistake. The Reference field only stores an Unique ID Value and not a text as displayed in the collection. I am now wondering how the reference field actually works.

Correct, you’ll need to change your query.

The reference field acts as a connector to other collections. For more information, see the articles on Reference Fields .
