undefined method `cliq_requests' for nil:NilClass - mysql

Question

I keep getting this annoying error consistently and I cannot solve it. I recently posted a question on the same topic and got no productive help.
I want users to request to join a group. Cliqs = Groups. All of my console tests seem correct, but I cannot seem to find a solution to my problem. The association is showing up, but I can't seem to get the update/accept method to run.
This is driving me crazy! How do I fix this?
Here is my code:
My Models:
class User < ActiveRecord::Base
has_many :uploads
has_one :owned_cliq, foreign_key: 'owner_id', class_name: 'Cliq', dependent: :destroy
has_many :cliq_memberships, dependent: :destroy
has_many :cliqs, through: :cliq_memberships
has_many :cliq_requests, dependent: :destroy
...
end
class Cliq < ActiveRecord::Base
belongs_to :owner, class_name: 'User'
has_many :cliq_memberships, dependent: :destroy
has_many :members, through: :cliq_memberships, source: :user
has_many :cliq_requests, dependent: :destroy #cliq_request_sender
has_many :pending_members, through: :cliq_requests, source: :user, foreign_key: 'user_id'
end
class CliqRequest < ActiveRecord::Base
#from
belongs_to :user
#to
belongs_to :cliq
#validate :not_member
#validate :not_pending
def accept
cliq.members << pending_member
destroy
end
end
My controller:
class CliqRequestsController < ApplicationController
def index
#incoming
##cliq_requests_received = CliqRequest.where(cliq: cliq)
#outgoing
##cliq_requests_sent = current_user.cliq_requests
end
def show
end
def create
cliq = Cliq.find_by(params[:id])
#cliq_request = current_user.cliq_requests.new(cliq: cliq)
if #cliq_request.save
redirect_to current_user #change to cliqs/cliq path later
else
redirect_to cliq_path
end
end
def update
#cliq = Cliq.find_by(id: params[:cliq_id])
#cliq_request = #cliq.cliq_requests.find_by(id: params[:id])
#cliq_request.accept
end
def destroy
#cliq_request.destroy
end
end
My View:
<h1><%= #cliq.name %></h1>
<%= link_to 'Request to join Cliq', '/cliqs/:cliq_id/cliq_requests', :method => :post %>
<% #cliq_members.each do |cliq_member| %>
<ul><%= link_to cliq_member.username, user_path(cliq_member) %></ul>
<% end %>
<% if #current_user = #cliq.owner %>
<% #cliq.pending_members.each do |pending_member| %>
<ul><%= link_to pending_member.username, user_path %>
<%= link_to "Accept", "/cliqs/:cliq_id/cliq_requests/:id/", :method => :put %>
<%= link_to "Deny", "/cliqs/:cliq_id/cliq_requests/:id/", :method => :delete %>
</ul>
<% end %>
<% end %>
My Routes:
resources :cliqs do
resources :cliq_requests
end

These lines appear malformed:
<%= link_to 'Request to join Cliq', '/cliqs/:cliq_id/cliq_requests', :method => :post %>
<%= link_to "Accept", "/cliqs/:cliq_id/cliq_requests/:id/", :method => :put %>
<%= link_to "Deny", "/cliqs/:cliq_id/cliq_requests/:id/", :method => :delete %>
I recommend you use path helpers [e.g. cliq_cliq_request_path(cliq, cliq_request) if you are using resourceful routing]. You can use rake routes for help. If you are seeing things like :cliq_id and and :id in your development.log or test.log as part of the URLs that are hit, those should instead be numbers. You can also interpolate the strings yourself (e.g. "/cliqs/#{cliq_id}/cliq_requests/#{cliq_request.id}") but this is usually more typing and certainly more fragile over time.
One of your problems may be that you are looping through a list of pending member names, which doesn't have all the data you need to form the link correctly. So your update action may be working fine, but you may not be passing it the right data.
Also this line:
if #current_user = #cliq.owner
is an assignment, and so will always return true. Presumably you mean ==
