This is an interesting use case but I am not sure it is currently possible within Adalo. Or at the very least will require some heavy work with outside services (API’s and connectors such as Zapier or Integromat).
I will see what I am able to achieve but it might be worthwhile thinking of other ways to achieve a similar goal.
Thanks for the welcome!
My understanding is what I’m asking seems related to the follow/unfollow information as well as the event/invite resources, but putting it all together is a bit unclear.
I did assume i may need zapier or api to make it work…
So you will need to use custom actions or zapier here to get this working properly. To get this working you will have to “pre-register” each invited user with the email address provided and a temporary password. Also set up an action here to update the logged in user and attach a relational property to that user with the user being created.
Then send an email to that person that they are invited etc and give a link to login to the app with their login credentials that have been generated for them.
Once they login, you should set up a link to a new screen to set a new password (for security). You can use a conditional action to do this only the first time they login. (or set it up with a boolean property (true/false) that they have in-fact updated their password.
