I have a Projects View that shows a list of all projects... I want to be able to say per project if the currently signed in user is a member or not, and what there role is...
In the project View I have: <% if team_member?(project.id, current_user) %> <td>Request to Join</td> <% else %> <td>Already Joined</td> <% end %>
then the helper:
module ProjectsHelper def team_member?(project_id, current_user) if current_user.permissions.find_by_project_id(project_id).role.try(:name).nil? true else false end end end
*** But that errors. Can you help me out?
Models: permission.rb
class Permission < ActiveRecord::Base belongs_to :user belongs_to :project belongs_to :role end project.rb
class Project < ActiveRecord::Base
has_many :permissions has_many :users, :through => :permissions
end role.rb
class Role < ActiveRecord::Base has_many :permissions end user.rb
class User < ActiveRecord::Base
belongs_to :instance has_many :books has_many :permissions has_many :projects, :through => :permissions
