Check if current user in a Sharepoint List

[Anonymous]

I want to check if the current user is in a sharepoint list called "Assignees"

The List Assignees has two columns:

User (People)

Job Types (Choice) 

I'm not quite sure how to approach this?  Do I have to pull out the Assignee emails into a collection or something first? 

Sorry, I'm more of a PHP person than a powerapps person!  Not quite sure how to frame my question.

Hi @Anonymous ,

Yes - firstly something fundamental - rename the field User to something else - this is a reserved word.

So assuming now you have two fields UserName and JobType in your list Assignees - at App OnStart

Set(
   vUserName,
   User().FullName
);
ClearCollect(
   vAssignees, 
   Assignees
);
Set(
   vJobType,
   Lookup(
      vAssignees,
      Lower(UserName) = Lower(vUserName),
      JobType
   )
);
Set(
   vInList,
   !isBlank(vJobType)
)
   

Out of this you will have 

• vJobType as the user's Job Type
• vInList as a true/false is they are in the list.

Thanks for your reply.

What I actually ended up doing was this:

Set(varUserEmail, User().Email);
If(CountRows(Filter('Assignees',varUserEmail in User.Email)) > 0,Set(varUserAssignee,true),Set(varUserAssignee,false));

Would there be any reason why your solution is better than mine in terms of best practice?  If so I could give it a go.

Hi @Anonymous ,

If you don't want the job title, CountRows on a Filtered list has the same effect as !IsBlank() on a Lookup - it is up to your preference. Neither are Delegable (neither is In), which is why I always do a collection to get rid of the annoying warning. You can shorten yours a bit (a boolean expression will automatically set a Boolean Variable to the same result) - also you can avoid In - I am assuming that are the same text - Lower() avoids case sensitive issues, but again is not Delegable. Note also below the reference to the list field name for the user's mail.

Set(varUserEmail, User().Email);
Set(
   varUserAssignee,
   CountRows(
      Filter(
         'Assignees',
         UserEmail = varUserEmail    //this needs to be the name of the field in the list
      )
   ) > 0
)
