I have a managed package that creates a scheduler as part of the post install script, my issue is that the schedluer created runs as the managed package name in the user filed not as the user who installed the package.....

can you run the post install script as the user who did the install?

I have a question about using batch and the passing in a Scope, lets say im processing a batch of 53 records, however due to other governance limits i need to use scope to limit 30 records per transaction.

e.g. 

Integer scopeSize = 30; jobId = Database.executeBatch(batch, scopeSize);

If I use the something like the above, will one or two entries be created in the Queue ?
 

Select Count(Id) FROM AsyncApexJob Where Status = 'Holding'

Everything I have read doesn’t seem to detail this bit….

I have some apex i want to run but only if Quotes are an enabled feature, i have tried to check this by doing the following.

public static Boolean sfQuotesEnabled () {
        boolean enabled;
        // sObject types to describe
        String[] types = new String[]{'Quote'};
            Schema.DescribeSobjectResult[] results;
            try{
                // Make the describe call
        		results = Schema.describeSObjects(types);
            }catch(DmlException e){
        		System.debug('sfQuotesEnabled: failed to get object type');
                enabled = false;
            }
        System.debug('Got describe information for ' + results.size() + ' sObjects.');
        
        if(results.size() > 0){
            enabled = true;          
        }
        return  enabled;

Hello i have a very simple LWC component that runs on a custom record, it takes in the rec id as a paramater calls apex, and displayes the response message to the user.

The issue i am having is when writing a Jest test for this i encounter errors even though my component / test is basisicly identical to the one seen in the examples: (https://github.com/trailheadapps/lwc-recipes/tree/master/force-app/main/default/lwc/apexImperativeMethod) 

Can anyone help me corrrect this test so that it no longer fails / causes the other tests to fail.

Below is the HTML of my LWC:

<template>
    <div>
        <p><b>{label.Data_Sync_Heading}</b></p>
        <p>{syncMessage}</p>
    </div>
</template>

Below is the .js of my LWC:

import { LightningElement, api, track } from 'lwc';
import syncData from '@salesforce/apex/DataController.syncData';
import Data_Sync_Fail from '@salesforce/label/c.Data_Sync_Fail';
import Data_Sync_Default_Message from '@salesforce/label/c.Data_Sync_Default_Message';
import Data_Sync_Heading from '@salesforce/label/c.Data_Sync_Heading';



export default class syncDataLwc extends LightningElement {
    @api recordId;
    
    @track syncMessage = Data_Sync_Default_Message;
    @track syncDone = false;

    // Expose the labels to use in the template.
    label = {
        Data_Sync_Heading
    };

    connectedCallback() {
        syncData({rec: this.recordId})
         .then (response => {
             this.syncMessage = response;
             this.syncDone = true;
         })
         .catch(() => {
             this.syncMessage = Data_Sync_Fail;
             this.syncDone = true;
         });
    }

Below is the .JEST test code for my LWC:

import { createElement } from 'lwc';
import syncDataLwc from 'c/syncDataLwc';
import Data_Sync_Fail from '@salesforce/label/c.Data_Sync_Fail';

jest.mock("@salesforce/label/c.Data_Sync_Fail", () => {

        });
    });

                APEX_REC_SUCCESS
            );

        });
    });
});

I am creating some Jest tests for my LWC components and i am struggeling to work out how to test / mock the apex call outs, in this basic component i have one but when i add a mock for the apex it causes all tests to fail.

Could somone point me in the right direction here?

Hello i have toast messages that display to users based on diffrent rules, i need this test to be translatable / as well as allow overridable by system admins when the managed package is deployed.

I beleave Custom Metadata fields in conjunction with translation workbench will allow this but i have not idea how to retrieve the data in SOQL, could somone give me an example?

when i try the below all i get is an empty entry.

SELECT Label, ExampleNamespace__Ex_example_field__c FROM ExampleNamespace__Ex_example__mdt

I have an app that contains various toast messages based on the user selecting different options on the form, currently the messages are all hard coded and in the base language (English) however i would like to give admins the ability to modify the base text of the message as well as translate it for users in different countries. 

Is there a 'best practices' way of doing this?

Hello i have toast messages that display to users based on diffrent rules, i need this test to be translatable / as well as allow overridable by system admins when the managed package is deployed.

I beleave Custom Metadata fields in conjunction with translation workbench will allow this but i have not idea how to retrieve the data in SOQL, could somone give me an example?

when i try the below all i get is an empty entry.

SELECT Label, ExampleNamespace__Ex_example_field__c FROM ExampleNamespace__Ex_example__mdt

I am currently trying to complete the trailhead 'Create a Hello World Lightning Web Component' section where you deploy the lightning web component from VSCode to your org, and im hitting the below error.

Starting SFDX: Deploy Source to Org

As far as i can see i have followed the instructions to the letter, and cant seem to correct the error.

Any suggestions would be greatly appreachiated.
