Power Platform Community Forum Thread Details

I want to create some power apps, but I'm not sure if I should use a canvas app or a model-driven app.

I have read the model-driven application documentation and started to build a model and a app. I want to use a model-driven app because I want to use the same app for tablet, smartphone and computer and I don't want to care about the design.

But it seems to me that I can't map all my processes.

1 I want to have a main page with all enteries of my first entity "celebration" and everything else (e.g. invited people) should be in a subarea/subpage. So when I select a particular celebration and then "invited people", I only want to see and edit the invited people for that particular celebration. I know I could do that with filters on each page separately, but that's not convenient.
Is that possible? I couldn't find a solution in App Designer.

2. I also want to create a grouping for the people (in pairs or as triplets). So I have an entity "group" (columns: celebration_id; group_id, which is assigned automatically) and entity "groupmembers" (columns: person_id; group_id). Now I want to select people and put them together in groups. Once I have selected the people, I need to automatically create an entry for the entity group and then create the entries for group members (who should have the newly created group as group_id). Is it possible to create the group entry automatically and add the created ID for the group member entries without explicitly creating the group? I could only find the business process and there I can only select one entity and not create an entry for another entity.

Thanks in advance

Hi @sandra1

Let me try to unpack things a little.

1) Do you have your celebrations in one entity and people in another entity, or are the people just attributes of a celebration? I think what you want is an entity with the celebrations, with a default view listing the attributes of the celebration you want to see, and an entity with the people who may or may not be invited. Then you can add a subgrid to the celebration entity form containing people.

2) This part is a little confusing. You shouldn't be referencing the GUIDs for entities, if you create a Lookup column, it will automatically handle the connection for you. For example, if you create a Group entity and a People entity, then create a Lookup field called Group connected to the Group entity, on the People entity, it will create a relationship for you of Group > People.
