call within a callback, just return the promise
and chain the .then()
at the outer level of the chain.
As you have some variables that need to available in the next then
callback (like nameId
) you could use Promise.all
to pass an array to the next callback in the chain, and include such variables in it:

After months of working without any trouble, now when trying to make login, this error appears. The code shown is simplified, when it arrives at "Parse.User.logIn" is when the error happens. There are some similar questions here, but all of them are related to CORS, it runs proper on local server, but as we host it does not return data and display error in console as :
...ANSWER
Answered 2018-Aug-08 at 21:01You are likely using a new version of the SDK (2.0.0), which contains many breaking changes compared to 1.x, without knowing it.
There are two possibilities to resolve the issue:
- Use parse-server 2.8.3 which was published yesterday
- Use the proper SDK version (see here) by pointing your parse SDK version to: the 1.11.1 (https://unpkg.com/parse@1.11.1/dist/parse.js)

nested inside a UITableViewCell
:
The number inside a collection view cell gets updated on a different view, so when I return back to this screen, I want to be able to refresh the view and the new numbers are reflected in their cells. I have a model called topUserModel
in my collection view that I populate with data from my firebase database. When I pull down to refresh, the following function is run from inside my main table view:
ANSWER
Answered 2018-Jun-07 at 04:51You shouldn't call dequeueReusableCell
anywhere but in cellForRowAt
.
In order to get the currently displayed cell (if any) you use cellForRowAt:
; this may return nil
if the row isn't currently onscreen.
Once you have the cell you can reload it's data and refresh its collection view.

QUESTION
I have a Laravel project running version 5.6. The connected database is mongodb with the jenssegers/mongodb package.
I wrote a single Unittest to test a function related to the User.
The test creates new users in a configured test mongodb database.
I want to refresh the database after each test run so I use the RefreshDatabase
Trait.
When using the RefreshDatabase
Trait I get the following error when running my test:
There was 1 error:
1) Tests\Unit\UserTest::it_gets_top_user Error: Call to a member function beginTransaction() on null
When not using the Trait the test creates all the necessary stuff in the database and performs the assertion without an error.
The test looks like this:
...ANSWER
Answered 2018-Mar-22 at 19:00The problem seems to be, that the RefreshDatabase
Trait does not work at all for a MongoDB environment.
I solved the above problem by creating my own RefreshDatabase
Trait in the testing/
directory of my Laravel project.
The Trait looks like this:

I am using Angular 4 with Firebase and AngularFire. I want to display on my Html code the first top 10 users, so my code is
...ANSWER
Answered 2017-Sep-21 at 10:55After some testing I discovered what's happening:
The thing is that the .reverse()
function not only returns a reversed array, but reverses the array itself. And this change to topusers
result in the Observable firing .map()
once again, which reverses the array back to its original form.
To solve this problem simply change the return statement to return topusers.slice().reverse();
. The .slice()
function returns a new copy of the array, which will prevent this problem.
