Hi All,
I’ve been stuck on something for a few days and wanted to get the community’s help since I expect others may have had to solve for this. I recently built a direct messaging system for users in our app. I have two relevant data types - Thread and Messages. Each thread contains a list of users and a list of messages. Each message is associated with a Thread, and has other fields including Read By (List of Users), Sender (user) and Body (text).
The flow is as follows:
- User presses a button opening a popup where they can select users to add to the Thread. The selected List of users are stored in a custom state
- Create button creates the Thread, adding the list of users from the custom state, and opens the chat window
I want to prevent users from creating a Thread that contains the same list of users as any Thread existing in the database. For example, if John, Sally, and Louis already have a conversation Thread created, I want to alert John and prevent the creation of an additional Thread if John attempts to create a Thread containing Sally and Louis, via workflows. Has anyone had to do something similar and had success? Many thanks.
