如何使用form_for在rails 4中创建嵌套资源

Question

company.rb

class Company < ActiveRecord::Base
  has_many :jobs, dependent: :destroy
end

job.rb

class Job < ActiveRecord::Base
  belongs_to :company
end

的routes.rb

resources :companies do
     resources :jobs
end

我想使用form_for创建一个新工作，所以我这样做：

<%= form_for(@company_job do |f| %>
...
<% end %> 

或

<%= form_for(:company_job, url: company_jobs_path do |f| %>
...
<% end %> 

但他们都得到错误：

Routing Error
No route matches [POST] "/jobs"

如何将表单发布到/company_jobs_path (url like this /companys/:company_id/jobs(.:format))

感谢您的回答！

Answer 1

视图：

form_for @company do |f|
  # company fields go here
  f.fields_for :jobs do |f2|
    # job fields go here
  end
end

模型：

class Company < ActiveRecord::Base
  has_many :jobs, dependent: :destroy
  accepts_nested_attributes_for :jobs
end
