问题 I have two models Jobs and Questions. A job has many questions and questions belong to a job. I've set up the resources in the model, as well as the routes. I am having an issue trying to link_to the Show method of the questions controller on the questions#index page. My rake routes say that the path should be job_question_path with the two necessary :id's being :job_id and :id , so I tried: <td><%= link_to 'Show', job_question_path(@job, question) %></td> and got the error: No route matches

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post.

Where I'm running into trouble are the complex resources. For instance, I have a resource for a comic book. ComicBook has all

问题 I have two models: Schedule and Project. Schedule belongs_To Project and Project has_one schedule. The routes for schedule and Project are nested like this: get 'projects/current', to: 'projects#show_current', as: :current_freelancer_projects resources :projects do resources :schedules end When I run rake routes, it says the path to make a new schedule is: new_project_schedule GET /projects/:project_id/schedules/new(.:format) The problem is, when I include a link to new_project_Schedule on a

问题 In my application I have the concept of a Draw, and that Draw has to always be contained within an Order. A Draw has a set of attributes: background_color, font_size, ... Quoting the famous REST thesis: Any information that can be named can be a resource: a document or image, a temporal service (e.g. "today's weather in Los Angeles"), a collection of other resources, a non-virtual object (e.g. a person), and so on.
