get the uuid in an object array with Firebase

Hello I would like to know if there would be a method to recover the uuid when I push data in my table I put you in the screenshot below
the code
push(ref(db, `/users/${auth.currentUser.uid}/user/sensors`), {
name: registerInformation.nameBox,
id: registerInformation.idBox,
categories: registerInformation.categories,
routine: registerInformation.routine,
});

The push function returns a Reference object, from which you can get the key with something like this:
const newRef = push(ref(db, `/users/${auth.currentUser.uid}/user/sensors`), {
name: registerInformation.nameBox,
id: registerInformation.idBox,
categories: registerInformation.categories,
routine: registerInformation.routine,
});
console.log(newRef.key);
If you want to use that key in the write operation, you can also separate the creating of the new ID from the writing of the data like this:
const newRef = push(ref(db, `/users/${auth.currentUser.uid}/user/sensors`));
console.log(newRef.key);
set(newRef, {
name: registerInformation.nameBox,
id: registerInformation.idBox,
categories: registerInformation.categories,
routine: registerInformation.routine,
});
In this snippet, the first line is a pure client-side operation that doesn't actually write anything to the database yet.

Access object property that is outside of array

My page object is structured so that I have all of the elements in an object and then an array of objects containing data about the fields that can be looped over to test max char length and error texts.
I would like the locator to reference a property that is outside the array so that the value does not need to be updated twice if the element changed.
Snippet from page object as an example...
module.exports = {
siteName: element(by.id('P662_NAME')),
fields: [
{
name: 'site name',
max: 45,
locator: element(by.id('P662_NAME'))
}
]
}
I have tried using the following with no luck...
this.siteName, this.siteName, module.exports.siteName
Is there a way to do this?

Your exporting looks pretty good. Import it correctly.

What you could do is set siteName as another variable and reference that in your fields object like this:
let siteName = "foo"; // now, updating this variable will also update the one in fields
let fields = [{
// other props
locator: siteName
}];
console.log(fields[0].locator); // expects "foo"
// module.exports = { siteName, fields };

Try this :
Export from a file like this
Sandbox: https://codesandbox.io/s/compassionate-bas-fg1c2
var siteName = "dsdsd";
var fields = [
{
name: "site name",
max: 45,
locator: "dsdsd"
}
];
module.exports = {
siteName,
fields
};;
Get it imported like this:
import { siteName } from "./test.js";
console.log(siteName);

firebase $add() .push() .set()

I am using firebase, and angularfire.
there are so many ways to do CRUD with the Firebase Api
actually, I still don't get what is specific difference for using
$add with $firebaseArray
.push() method
.set() method
I think they are technically same, I prefer to use .set method() without knowing the exact reason, why I'd using that. is there any specific reason to not use it? what is exactly $firebaseArray did? if we could just declare basic reference variable.
in this case:
var usersRef = Ref.child('users');
$scope.createUser = function() {
$scope.userRef.child($id).set({
name: name
});
};
or
$scope.data = $firebaseArray(Ref.child('users'));
$scope.createUser = function() {
$scope.data.child($id).$add({
name: name
});
};
thank you.

If I have the following data tree in Firebase:
{
users:
{
key: { name:"bob" }
}
}
When I do an $add, I will create a new item in the tree
$scope.data.child('users').$add({
name: name
});
Since $add uses the Push method in Firebase, new random Key will be used when pushing data to the child.
{
users:
{[
key: { name:"bob" },
key2: { name:"name" }
]}
}
If I do a set on the same Users object, I will overwrite the data that is already there. So, in your example, without specifying a key, you will overwrite the entire user object.
$scope.userRef.child('users').set({
name: name
});
};
This will result with this data
{
users:
{
name: "name"
}
}
This happens because any null values you pass to the Set method will delete any data that was originally there.
Passing null to set() will remove the data at the specified location.

Javascript reset object inside array

I have the below JS code in my Ember app that gets called;
myPanels.accordionPanels = [];
myPanels.accordionPanels.push({
panel: {
name: "my-grid",
type: 'comp',
props: [{
key: 'elementId',
value: "myCustomId"
}]
}
});
So as you can see, I start by setting myPanels.accordionPanels = [] every time and then push the object.
However, I got the following error
Assertion Failed: Attempted to register a view with an id already in
use: myCustomId
So I am assuming that the object inside is not getting reset & it is able to find the earlier created "myCustomId".
Am I resetting the array (or rather the object inside it) correctly ?

Since I am able to push values using:
accordionPanels = [];
accordionPanels.push({
panel: {
name: "my-grid",
type: 'comp',
props: [{
key: 'elementId',
value: "myCustomId"
}]
}
});
make sure myPanels.accordionPanels doesn't have any prototype associated with it.
Try to inspect its value as:
myPanels.accordionPanels = [];
console.log(myPanels.accordionPanels); // see if it has values.
You can delete value using :
delete myPanels.accordionPanels PROTOTYPE

ExtJS creating record from existing store

I have created an ext store like so:
var store = new Ext.data.JsonStore({
root: 'vars',
fields: [{ name: 'rec_id', mapping: 'rec' }, { name: 'identity', mapping: 'id'}]
});
This works alright when I add data to the store via loadData(); and some json which looks like:
{ vars : {rec: '1', id:'John'} }
My problem is that if I use add(); to get this record into the store I have to first create it as an Ext.data.Record object.
I do this as pointed out here: https://stackoverflow.com/a/7828701/1749630 and it works ok.
The issue I have is that the records are entered with their mapped parameters rather than the ones I set. I.e, 'rec_id' becomes 'rec' and 'identity' becomes 'id'.
What am I doing wrong here?

You need to do the mapping manually, something like this:
var myNewRecord = new store.recordType({
rec_id: vars.rec,
identity: vars.id
});
store.add(myNewRecord);
