Displaying distinct items from a JSON object array based on one field of the object

Here's a simplified version of a JSON array which I am getting back from a Jira REST endpoint. I store the issues in a PowerApps collection called jiraRawData.

"issues":[
   {
      "id":"1",
      "assignee":null
   },
   {
      "id":"2",
      "assignee":{
         "displayName":"john"
      }
   },
   {
      "id":"3",
      "assignee":{
         "displayName":"john"
      }
   },
   {
      "id":"4",
      "assignee":{
         "displayName":"mary"
      }
   }
]

 I want to display issues in a Gallery component and I can do that no problem.

However what I would like to do is to display the unique assignee names only so for the input above I would just like to see the following in my gallery

 

john

mary

 

  • I have tried assigning the Items property of the gallery component to  Distinct(jiraRawData, "assignee") but it doesn't work. I've tried so many things and I'm out of ideas.

 

  • I'm also having issues displaying the assignee in a gallery even when I just supply jiraRawData as the Items property I get the following error  Invalid use of '.'  when using ThisItem.fields.assignee.displayName as the Text attribute.

 

 

 Any help greatly appreciated.

The the distinct function Distinct(_Jira,assignee)

@rubin_boer I've tried what you've suggested above. Still having an issue. Screenshots below as requested. I load my Collection using the following line 

ClearCollect(jiraRawData, JIRACloud.GetIssuesForJQL("project = MYPROJECT AND issuetype in (standardIssueTypes(), subTaskIssueTypes(), Bug, Epic, Spike, Story, Task, Bug-Subtask, Sub-task) AND status in (Blocked,"&Char(34)&"In Progress"&Char(34)&", Open) AND fixVersion = 11.0.0 ORDER BY created DESC").issues);

I think my issue seems to be that I can't do this. How would I get around this seeing as displayName only exists within assignee sometimes. Otherwise assignee is null.

 

 

 

 

Distinct(jiraRawData, assignee.displayName)

You may want to filter the data to get the non-null ones, before using Distinct to get the unique list of displayName values.

Distinct(Filter(Issues, !IsBlank(assignee)), assignee.displayName)
