Rails 4 - Путь

Question

Я пытаюсь выяснить, рельсы 4.

У меня есть модель проекта и модель project_question.

Вопрос проекта относится к проекту.

Мне нужна форма, которая перенаправляется на страницу проекта после отправки вопроса. Я постоянно возвращаюсь к списку проектов, а не к конкретному проекту, в отношении которого был задан вопрос. Я изо всех сил пытаюсь понять, как изучать рельсы.

В моей project_question_form у меня есть:

<div class="containerfluid"> 
    <div class="row"> 
    <div class="col-md-10 col-md-offset-1"> 

     <div class="header-project">What would you like to know?</div> 

     <%= render 'form' %> 
     <div class="formminor"> 
     <%= link_to 'Back', projects_path(@project) %> 
     </div> 
    </div> 
    </div> 
</div> 

Я ожидаю, что квадратные скобки бит в «Назад» ссылку, чтобы вернуться на страницу проекта, что пользователь был когда они нажали «задать вопрос». Вместо этого пользователь возвращается на страницу с указанием индекса всех проектов.

В моей задать форму вопроса, у меня есть:

<div class="containerfluid"> 
    <div class="row"> 
    <div class="col-md-10 col-md-offset-1"> 
     <%= simple_form_for :project_questions do |f| %> 
       <%= f.input :project_id, as: :hidden, input_html: {value: @project_question_id} %> 
       <%= f.input :title, label: 'Question:', :label_html => {:class => 'question-title'}, placeholder: 'Type your question here', :input_html => {:style => 'width: 100%', :rows => 4, class: 'response-project'} %> 
       <%= f.input :content, label: 'Is there any context or other information?', :label_html => {:class => 'question-title'}, placeholder: 'Context might help to answer your question', :input_html => {:style => 'width: 100%', :rows => 5, class: 'response-project'} %> 

      <br><br><br> 
       <%= f.button :submit, 'Send!', :class => "cpb" %> 

    <% end %> 
    </div> 
    </div> 
</div> 

В моем routes.rb, у меня есть:

resources :projects do 
    resources :project_questions do 
     resources :project_answers 
    end 
    end 

Может кто-нибудь увидеть, что я сделал не так? Я попытался использовать (@project_id) и (@ project.id) вместо (@project) в первом виде. Ни одна из этих альтернатив не работает.

Мой projects_controller имеет:

class ProjectsController < ApplicationController 
    #layout :projects_student_layout 

    before_action :authenticate_user! 

    # GET /projects 
    # GET /projects.json

    #can i have more than one index? do i need to change something in the routes? if i want to list the related projects and the expiring projects - how do i do that within one index? 

    #is there a way to order these, so that for educators they are in order of course and for students they are in order of next milestone date? 
    #@projects.order("created_at DESC") 
    end 

    # def index2

Когда я расслоение EXEC рек маршрутов (как предложено ниже), я получаю много маршрутов для всех моделей. Те, которые включают в себя project_question являются:

project_answers#destroy 
        project_project_questions GET  /projects/:project_id/project_questions(.:format)            project_questions#index

Мой project_question контроллер:

    before_action :set_project_question, only: [:show, :edit, :update, :destroy] 

    # GET /project_questions 
    # GET /project_questions.json

    end 

    # GET /project_questions/1 
    # GET /project_questions/1.json 
    def show 
    end 

    # GET /project_questions/new 
    def new 
    @project_question = ProjectQuestion.new 
    @project_id = params[:project_id] 
    @project_question.project_answers[0] = ProjectAnswer.new 

    end

    end 

    # POST /project_questions 
    # POST /project_questions.json 
    def create 
    @project_question = ProjectQuestion.new(project_question_params) 
    @project_question.project_id = project_question_params[:project_id] 


    respond_to do |format|

     format.html { redirect_to @project_question, notice: 'Project question was successfully created.' }

    def project_question_params 
     params[:project_question].permit(:id, :title, :content, :project_id, :user_id, 
     project_answer_atttibutes: [:id, :answer, :project_question_id, :user_id] 
    ) 
    end 
end 

Эта ссылка находится в моих проектах показать страницу:

<%= link_to 'Ask a question', new_project_project_question_path(:project_id => @project.id) %> <% end %> 

Answer 1

Во-первых, попробуйте:

project_path(@project_id) 

Тогда, если это не сработает, то вам необходимо убедиться, что при переходе со страницы проекта на задайте страницу вопросов, вы передаете @project.id в качестве параметра, называемого project_id.

Answer 2

You sh ould использовать project_path(@project) вместо projects_path(@project).

Answer 3

Самое лучшее, что я хотел бы предложить запустить bundle exec rake routes

Затем получить определяют ваше имя пути и необходимые параметры. Исходя из вашей проблемы, мы не можем правильно ответить на правильный путь. Поэтому наилучшей практикой является использование рейк-маршрутов.

Answer 4

Не могли бы вы попробовать

project_path(@project_question_id) 

Answer 5

Вы должны определить @project в вашем new действия вашей ProjectQuestionsController ниже

def new 
    @project_question = ProjectQuestion.new 
    @project = Project.find(params[:project_id]) #here 
    @project_question.project_answers[0] = ProjectAnswer.new 
end 

и изменить link_to в

<%= link_to 'Back', project_path(@project) %>
