I am trying to develop a friendship system like facebook. I have follow
for guidance the two following sources
How to Implement a Friendship Model in Rails 3 for a Social Networking
Application?
Railsspace book chapter 14, which can only be downloaded i believed
I am a bit confused on the way railsspace has been building there
relationship. What i am trying to do his to show in a views my
pending_request, accepted_request and declined_request. The books seem
to suggest the following relationship
FriendshipModel
class Friendship < ActiveRecord::Base
belongs_to :customer
belongs_to :friend, :class_name => 'Customer', :foreign_key =>
'friend_id'
CustomerModel
class Customer < ActiveRecord::Base
#RELATIONSHIP
has_many :friendships
has_many :friends, :through => :friendships,
:conditions => "status = 'accepted'"
has_many :requested_friends,
:through => :friendships,
:source => :friend,
:conditions => "status = 'requested'"
has_many :pending_friends,
:through => :friendships,
:source => :friend,
:conditions => "status = 'pending'"
The issues i am having his how can i access friends who are pendings,
friends who are requested. I have the following view in my index
(friendship/index)
<div><h1>Request</h1></div>
<table>
<% @customer.friends.each do |friend| %>
<tr>
<td><%= link_to friend.first_name, '#' %></td>
</tr>
<% end %>
</table>
But i get the following errors
NoMethodError in Friends#index
Showing /app/views/friends/index.html.erb where line #15 raised:
undefined method `friends' for #<Array:0xb6144040>
Extracted source (around line #15):
12:
13: <div><h1>Request</h1></div>
14: <table>
15: <% @customer.friends.each do |friend| %>
16: <tr>
17: <td><%= link_to friend.first_name, '#' %></td>
18: </tr>
Mind you, my model is called friendship, my controller his called
friends ( not the best name but its more for practise learning I did)
Here the model
# Table name: friendships
#
# id :integer not null, primary key
# customer_id :integer
# friend_id :integer
# created_at :datetime not null
# updated_at :datetime not null
# approved :string(255)
#
Customer Schema
# Table name: customers
#
# id :integer not null, primary key
# email :string(255) default(""), not null
# created_at :datetime not null
# updated_at :datetime not null
# first_name :string(255)
# middle_name :string(255)
# last_name :string(255)
# isadmin :boolean default(FALSE)
# isMod :boolean default(FALSE)
