Question

I have implemented a save buttons for jobs and it work fine now i want to list some of the saved jobs in the jobs index page for this i have this code
<h3>Saved Jobs</h3>
<ul>
<% #user.saved_jobs.limit(5).order(:created_at).reverse_order.each do |saved_job| %>
<li><%= link_to saved_job.job.title, saved_job.job.url %>
<span class="delete_button">
<%= link_to "X", saved_job, :method => :delete, :remote => true %></span></li>
<% end %>
</ul>
<%= link_to "see all", saved_jobs_path %>
but when i want access to the jobs index page i get this error undefined method saved_jobs' for nil:NilClass
this my saved_jobs controller
class SavedJobsController < ApplicationController
before_filter :authenticate_user!
def index
#saved_jobs = SavedJob.find_all_by_user_id(current_user.id)
end
def create
#job = Job.find(params[:saved_job][:job_id])
current_user.save_job!(#job)
respond_to do |format|
format.html { redirect_to #job }
format.js
end
end
def destroy
#job = SavedJob.find(params[:id]).job
current_user.saved_jobs.find(params[:id]).destroy
respond_to do |format|
format.html { redirect_to #job }
format.js
end
end
end
and this is my user controller
class ProfilesController < ApplicationController
before_filter :authenticate_user!
def show
#user = User.find_by_slug(params[:id])
if #user
#posts = Post.all
render action: :show
else
render file: 'public/404', status: 404, formats: [:html]
end
end
def index
#users = user_scope.paginate(page: params[:page], per_page: 2)
end
private
def user_scope
current_user ? User.where.not(id: current_user.id) : User.all
end
end

The error suggests that you didn't set #user in your controller action. Can you post the code from your controller?
Update based on controller code:
Your index action in SavedJobsController does not set #user. When you then call #user.saved_jobs.limit(5)..etc... in the view #user is nil, rather than current_user or whatever.
Additionally, you have set #saved_jobs - why not just use that instead of #user.saved_jobs?
for instance:
#in SavedJobsController
def index
#saved_jobs = current_user.saved_jobs.limit(5).order('created_at DESC')
end
and then, in your view:
<% #saved_jobs.each do |saved_job| %>
