Kevin,
How did you create the friends method? I got it working by hacking
around, but I am wondering how you accomplished the same result.
User model:
has_many :friend_invites, :class_name => "Friendship", :foreign_key
=> :invitee_id, :dependent => :destroy
has_many :friend_invitors, :class_name => "Friendship", :foreign_key
=> :invitor_id, :dependent => :destroy
has_many :accepted_invites, :class_name =>
"Friendship", :foreign_key => "invitee_id", :conditions => ['state
= ?', "active"]
has_many :accepted_invitors, :class_name =>
"Friendship", :foreign_key => "invitee_id", :conditions => ['state
= ?', "active"]
def friends
accepted_invites + accepted_invitors
end
Application:
<def tag="invite-button">
<% target = this %>
<do with="&Friendship.new">
<form controller="friendships" lifecycle="invite" unless="&target ==
current_user or current_user.friends">
<input type="hidden" name="friendship[invitee_id]" value="#
{target.id}" />
<submit label="Request as Friend" />
</form>
</do>
</def>
Works great by the way :)
Owen,
Ofcourse I will create a recipe when I got it working and tweaked. So
far everything I got is in this thread :) You can invite other users
with a button thanks to Kevin. Creating the other functions should be
straight forward with the great examples.
Best regards.
