Hi @Manoux ,
Adding what @dilon_perera has replied.
- You can choose to make unfavorite list instead of favorite list, so by default all users have favorite this list, this is one way of doing this, if you choose this way, you can look up komun template here,
Free Template - Komun for Community Support - In Progress
The Users and Projects collections have many-to-many relationship, it is the 3rd choice when adding relationship.
Here is projects collection linked to users and called unsubscribers, so at the beginning there will be no unsubscribers, meaning all users are subscribed to this.
Here is from users collection.
When showing project unsubscribers,
So the perspective is reverse, in your case, if you want users favorite the list by default, there is no need to update record, because by default all users are subscriber, and by the same logic if they want to unfavorite the list, they need to do something which is updating project record with add logged in user. (creating many-to-many relationship is by updating action and add or remove in the related field).
Let me know if I need to clarify further.
