Ruby on rails 嵌套资源-没有路由匹配

我的Rails4应用程序中的嵌套资源有问题。我错过了什么

• 我可以很好地查看participations/new.html.erb表单，但当我提交表单时，它返回“没有路径匹配[POST]”/executions/1-ales/participations/new”错误

• 例如，当我尝试编辑参与时，此url:localhost:3000/executions/1-ales/participations/15/edit返回“ActionController:：ParameterMissing in ParticipationsController#edit”和“param not found:participation”
  • 编辑并销毁index.html.erb文件中的链接，导致错误：

  ActionController:：UrlGenerationError in Participations#index

  没有路由匹配{:action=>“edit”，：controller=>“participations”，

  ：检查id=>，

  id=>nil，：format=>nil}缺少必需的键：[:id]“

app/views/participations/edit.html.erb

：hidden，：input_html=>{:value=>current_user.id}%>

app/views/participations/index.html.erb **导致应用程序出错的链接

<%= link_to 'Edit', edit_examination_participation_path(participation), :class => 'btn btn-small' %>
<%= link_to 'Delete', participation, method: :delete, data: { confirm: 'bla bla' }, :class => 'btn btn-small btn-danger' %>

“btn btn小”%>
“btn btn小btn危险”%>

创建参与：

在

app/views/participations/new.html.erb

中

替换

<%= simple_form_for @participation, as: :participation, url: new_examination_participation_path(@examination) do |f| %>

<%= simple_form_for @participation, as: :participation, url: edit_examination_participation_path(@examination) do |f| %>

<%= link_to 'Edit', edit_examination_participation_path(participation), :class => 'btn btn-small' %>
<%= link_to 'Delete', participation, method: :delete, data: { confirm: 'bla bla' }, :class => 'btn btn-small btn-danger' %>

与

与

“btn btn小”%>
“btn btn小btn危险”%>

注意：我强烈建议您阅读Rails指南中的相关内容。

您始终可以执行

rake routes

，并查看可用的路由列表。

当您发布有关路由的问题时，请确保添加rake路由的输出

<%= simple_form_for @participation, as: :participation, url: new_examination_participation_path(@examination) do |f| %>
    <%= f.input :user_id, :as => :hidden, :input_html => { :value => current_user.id } %>
    <%= f.input :examination_id, as: :hidden %>
    <%= f.input :language_preference, collection: ["English", "German"] %>
    <%= f.button :submit, "Register to Exam" %>
<% end %>

<%= simple_form_for @participation, as: :participation, url: edit_examination_participation_path(@examination) do |f| %>

    <%= f.input :language_preference, collection: ["English", "German"] %>
    <%= f.button :submit, "Register to Exam" %>
