阅读更多关于 Rails: Nested resources conflict, how to scope the index action depending on the called route

问题 Imagine you have two defined routes: map.resources articles map.resources categories, :has_many => :articles both accessible by helpers/paths articles_path # /articles category_articles_path(1) # /category/1/articles if you visit /articles , index action from ArticlesController is executed. if you visit /category/1/articles , index action from ArticlesController is executed too. So, what is the best approach for conditionally selecting only the scoped articles depending on the calling route?

I have gone through tons of the form_for nested resource questions and can't get any of the solutions to work for me. I figured its time to ask a personalized question. I have two models, jobs and questions, jobs has_many questions and questions belong_to jobs. I used scaffolding to create the controllers and models then nested the resources in the routes.rb. root :to => "pages#home" resources :jobs do resources :questions end get "pages/home" get "pages/about" get "pages/contact" class Job < ActiveRecord::Base has_many :questions end class Question < ActiveRecord::Base belongs_to :job end

阅读更多关于 RESTful API routes design: nested vs. non-nested

问题 My question is about the advantages of nesting resources when building URLs for API purposes. Consider the following two alternatives for accessing an employee resource: /api/employees?department=1 # flat Vs. /api/departments/1/employees # nested Now consider the task of developing a general purpose library to access REST resources from an API. If all routes were flat, such a REST wrapper library would only need to know the name of the resource being accessed: store.query('employees',

Does anybody have any tips for managing polymorphic nested resources in Rails 3?

I'm currently using mongoid (mongomapper isn't as compatible with Rails 3 yet as I would like), and comments are an embedded resource (mongoid can't yet handle polymorphic relational resources), which means that I do need the parent resource in order to find the comment. Are there any elegant ways to handle some of the following problems: In my controller, I need to find the parent before finding the comment: if params

问题 If there's one thing I've learned about Rails 3 is if I'm having a hard time doing something, I'm probably doing it wrong. So I'm looking for help. I have a few models which are related in a many to many relationship. I am able to create the associations in the models without a problem. My problem lies in how to build the controllers to work with these relationships. I'll try and give an example if you don't see where I'm going with this. For instance... class Account < ActiveRecord::Base has
