Model relationships: class Project < ActiveRecord::Base … has_one :project_team … end class ProjectTeam <

  • 0

Model relationships:

class Project < ActiveRecord::Base
  ...
  has_one :project_team
  ...
end

class ProjectTeam < ActiveRecord::Base
  belongs_to :project
end

Controller:

class Project::TeamController < ApplicationController
  ...
end

Routes:

resources :projects do
  namespace :project do
    resources :team
  end
end

Form code:

= form_for @project do |f|

When I visit the new Project form, I get the following error:

No route matches {:controller=>"project/team", :project_id=>#<Project id: nil, user_id: 1 ...

I’ve tried many variations of this:

= form_for [:project, :team, @project] do |f|

To no avail. The routes are just barely off. But, I’m on the new project form, so I’m wondering why it’s trying to grab the project team for that anyway.

Thanks for the help! [:

    I’m not sure of the issue, but to fix it, I just pluralized my controller name.
