我正在尝试制作rails 4应用程序。
我有一个项目模型和一个project_questions模型。
项目问题属于项目。
我已经制作了一个项目问题表单，用户可以用它来询问有关项目的问题。
我的麻烦是，当我按提交时，出现路线错误，表示没有匹配的路线。我不明白，因为我通过脚手架制作了模型，我理解这是自动制作主要路线。
我的结构是：
Project_question表单（使用简单形式gem）：
<%= 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 %>
路线：
resources :projects do
resources :project_questions do
resources :project_answers
end
end
项目问题的控制器：

错误消息显示：
No route matches [POST] "/projects/70/project_questions/new"
我不知道在哪里制作路线或如何为新路线制作路线。我认为这是生成脚手架时自动化过程的一部分。有人能看出出了什么问题吗？
我发现SO上的另一个用户有嵌套路由问题。他们改变了控制器显示动作如下：
def show
@user = User.find(params[:user_id])
@album = @user.albums.find(params[:id])
@photo = @album.photos.build
end
目前，我在项目问题中的表演行动是空的。但是，它属于我认为会涵盖它的项目。是否有一系列步骤可以使嵌套控制器工作？
谢谢

没有路线匹配[POST]＆＃34; / projects / 70 / project_questions / new＆＃34;
您已定义 嵌套路线 ，因此它应该是这样的
<%= simple_form_for [@project, @project_question] do |f| %>
答案 1 :(得分：0)
问题不在于你的route.rb文件在你的表单中。你没有正确地指出你应该去哪里。
将表单更改为以下内容。
<%= simple_form_for [@project, @project_question] 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 %>
你应该将一个数组作为第一个参数传递给simple_form_for方法（负责设置正确的表单URL）
