Hello,
Here is the logic that I am trying to achieve. I have a User Model and the business rule is that user can accept maximum 5 friends requests.
for this I have an accept method in User Model which looks similar to below code snippet
def accept(friend) raise ArgumentError if self.friends.count >= MAX_FRIENDS_ALLOWED ... ... #code to add friend to friends list end As you can see that I basically query for count of friends for a user and if the count is greater then or equal to MAX_FRIENDS_ALLOWED the friend accept request should not go through.
From the UI perspective I have a link_to_remote, "Accept" link that calls an action which calls the User Model's "accept" method. Basically UI looks like
FRIEND NAME | Action
