我想弄清楚轨道4.
我有一个项目模型和一个project_question模型。
项目问题属于项目。
我想要一个在提交问题后重定向到项目页面的表单。我不断被引导回到项目列表，而不是询问问题的具体项目。我正在努力弄清楚如何学习铁轨。
在我的project_question_form中，我有：
<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>
我希望“后退”链接中的括号位回到用户点击“提出问题”时所在的项目页面。相反，用户将被带回列出所有项目索引的页面。
在我问一个问题表格时，我有：
<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>
在我的routes.rb中，我有：
resources :projects do
resources :project_questions do
resources :project_answers
end
end
谁能看到我做错了什么？我尝试在第一种形式中使用（@project_id）和（@ project.id）代替（@project）。这些替代方案都不起作用。
我的projects_controller有：
class ProjectsController < ApplicationController
#layout :projects_student_layout
before_action :authenticate_user!
# GET /projects
# GET /projects.json
def index
@projects = current_user.projects
#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
# @projects = Project.find_xxx_xx
# end

@projects = Project.find(:all)

当我捆绑exec rake路线时（如下所示），我为所有模型获得了很多路线。包含project_question的是：
project_answers#destroy
project_project_questions GET /projects/:project_id/project_questions(.:format) project_questions#index
POST /projects/:project_id/project_questions(.:format) project_questions#create
new_project_project_question GET /projects/:project_id/project_questions/new(.:format) project_questions#new
edit_project_project_question GET /projects/:project_id/project_questions/:id/edit(.:format) project_questions#edit
project_project_question GET /projects/:project_id/project_questions/:id(.:format) project_questions#show
PATCH /projects/:project_id/project_questions/:id(.:format) project_questions#update
PUT /projects/:project_id/project_questions/:id(.:format) project_questions#update
DELETE /projects/:project_id/project_questions/:id(.:format) project_questions#destroy
乍得的路线建议：
projects GET /projects(.:format) projects#index
POST /projects(.:format) projects#create
new_project GET /projects/new(.:format) projects#new
edit_project GET /projects/:id/edit(.:format) projects#edit
project GET /projects/:id(.:format) projects#show
PATCH /projects/:id(.:format) projects#update
PUT /projects/:id(.:format) projects#update
DELETE /projects/:id(.:format) projects#destroy
我的project_question控制器：
class ProjectQuestionsController < ApplicationController
before_action :set_project_question, only: [:show, :edit, :update, :destroy]
# GET /project_questions
# GET /project_questions.json
def index
@project_questions = ProjectQuestion.all
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
# GET /project_questions/1/edit
def edit
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|
if @project_question.save
format.html { redirect_to @project_question, notice: 'Project question was successfully created.' }
format.json { render action: 'show', status: :created, location: @project_question }
else
format.html { render action: 'new' }
format.json { render json: @project_question.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /project_questions/1
# PATCH/PUT /project_questions/1.json
def update
respond_to do |format|
if @project_question.update(project_question_params)
format.html { redirect_to @project_question, notice: 'Project question was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: 'edit' }
format.json { render json: @project_question.errors, status: :unprocessable_entity }
end
end
end
# DELETE /project_questions/1
# DELETE /project_questions/1.json
def destroy
@project_question.destroy
respond_to do |format|
format.html { redirect_to project_questions_url }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_project_question
@project_question = ProjectQuestion.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
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]

此链接位于我的项目展示页面中：
<%= link_to 'Ask a question', new_project_project_question_path(:project_id => @project.id) %> <% end %>
答案 0 :(得分：0)
您应该使用project_path(@project)代替projects_path(@project)。
答案 1 :(得分：0)
我建议运行的最好的事情
var comp = jasmineReact.render(<Comp />);
expect(comp.state.something).toBe('else');
然后确定您的路径名称和所需参数。根据您的问题，我们无法直接回答正确的路径。所以最佳做法是使用rake路线。
答案 2 :(得分：0)
你能试试吗
project_path(@project_question_id)
答案 3 :(得分：0)
首先，试试：
project_path(@project_id)
然后，如果这不起作用，那么您需要确保当您从项目页面转到询问问题页面时，您将@project.id作为名为{{1}的参数传递}。
答案 4 :(得分：0)
您必须在@project的{{1}}操作中定义new，如下所示
ProjectQuestionsController并将您的def new
@project_question = ProjectQuestion.new
@project = Project.find(params[:project_id]) #here
@project_question.project_answers[0] = ProjectAnswer.new
end
更改为
link_to
