Question

我想基于当前的user.id == company.user_id访问show page，我想只显示特定用户添加的公司详细信息，当company_path链接点击时。

companies_controller.rb文件是

class CompaniesController < ApplicationController

  def index
    @companies = Company.all            
  end

  def show
    @company = Company.where(user_id:company.user_id)
    @company_user_id = current_user.id               
  end

  def company_params
    params.require(:company).permit(:c_name, :c_description)
  end

  def find_company
    @company = Company.find(params[:id]) 
  end

end

routes.rb文件为

Rails.application.routes.draw do
  devise_for :users
  resources :jobs
  resources :companies
  root 'jobs#index'
end

rake路线信息为，

          DELETE /jobs/:id(.:format)                          jobs#destroy
  user_companies GET    /users/:user_id/companies(.:format)          companies#index
                 POST   /users/:user_id/companies(.:format)          companies#create
new_user_company GET    /users/:user_id/companies/new(.:format)      companies#new
edit_user_company GET    /users/:user_id/companies/:id/edit(.:format) companies#edit
    user_company GET    /users/:user_id/companies/:id(.:format)      companies#show
                 PATCH  /users/:user_id/companies/:id(.:format)      companies#update
                 PUT    /users/:user_id/companies/:id(.:format)      companies#update
                 DELETE /users/:user_id/companies/:id(.:format)      companies#destroy
           users GET    /users(.:format)                             users#index
                 POST   /users(.:format)                             users#create
        new_user GET    /users/new(.:format)                         users#new
       edit_user GET    /users/:id/edit(.:format)                    users#edit
            user GET    /users/:id(.:format)                         users#show
                 PATCH  /users/:id(.:format)                         users#update
                 PUT    /users/:id(.:format)                         users#update
                 DELETE /users/:id(.:format)                         users#destroy
            root GET    /                                            jobs#index

Answer 1

您应该将公司资源包装在用户资源中：

Rails.application.routes.draw do
  resources :users do
    resources :companies
  end
end

Answer 2

将show action修改为

def show
  @company = Company.find_by_user_id(current_user.id)
  @company_user_id = current_user.id
end

并将您的路线修改为

Rails.application.routes.draw do
  devise_for :users
  resources :jobs
  resources :companies, except: :show do
    get :show, on: :collection, as: :show
  end
  root 'jobs#index'
end

而不是关注

<%= link_to "Companies", company_path(@company) %>

使用路径

<%= link_to "Companies", show_companies_path %>

我希望这会对你有帮助!!!

Answer 3

show方法不应该显示给很多公司。您应该使用索引方法。

最好的选择是将公司定义为用户的嵌套资源（如eugene建议的那样）。

def index
  if params[:user_id] && @user = User.find_by(id: params[:user_id])
    @companies = @user.companies
  else
    @companies = Company.all
  end
end

然后，在控制器中：

<%= link_to "View companies", user_companies_path(@user.id) %>

在视图中，要调用索引，您应该

!Sub arn:aws:kinesis:${AWS::Region}:${AWS::AccountId}:stream/xxxx

这将在@user中显示用户的公司。如果要显示current_user公司，只需将@user替换为current_user

即可

如何仅显示属于当前用户的公司
