Question

我如何在一个可以设置为不同路径的表单部分中使用动态路径，具体取决于我正在调用表单部分的页面？

例如，在我的_form.html.erb文件的底部，我希望能够根据我调用它的页面动态更改“取消”路径：

<div class="row">
  <div class="col-md-6 offset-md-3">
    <%= form_for(@chef, :html => {class: "form-horizontal", role: "form" }) do |f| %>

      <div class="form-group">
        <%= f.label :chefname %>
        <%= f.text_field :chefname, class: "form-control", 
                                placeholder: "Chef Name", 
                                autofocus: true %>
      </div>

      <div class="form-group">
        <%= f.label :email %>
        <%= f.email_field :email, class: "form-control", 
                                 placeholder: "Email" %>
      </div>

      <div class="form-group">
        <%= f.label :password %>
        <%= f.password_field :password, class: "form-control", 
                                 placeholder: "Must be at least 5 characters" %>
      </div>

      <div class="form-group">
        <%= f.label :password_confrimation, "Confirm Password" %>
        <%= f.password_field :password_confrimation, class: "form-control", 
                                 placeholder: "Confirm Password" %>
      </div>


      <div class="form-group">
        <%= f.submit "#{action} Account", class: "btn btn-primary" %>
      </div>

    <% end %>

    <%= link_to "Cancel", cancel %>

    <hr>

    <% if logged_in? && (current_chef == @chef || current_chef.admin?) %>
      <%= link_to "Delete Account", chef_path(@chef), method: :delete, 
                                     class: "btn btn-sm btn-outline-danger",
                                     data: { confirm: "Are you sure you want to delete this account and all corresponding recipes?" } %>
    <% end %>
  </div>
</div>

然后在我正在调用它的new.html.erb中，我尝试将'cancel'设置为路径。

<%= render "form", action: "Create", cancel: root_path %>

这样做的正确方法是什么？它似乎在我的浏览器中工作，但在我的测试中我得到未定义的局部变量或方法'取消'。

ActionView::Template::Error: undefined local variable or method `cancel' for #<#<Class:0x00000001da1e38>:0x0000000322cf10>

你非常接近。您只需指定cancel作为locals的一部分即可将其发布到部分内容：

<%= render "form", action: "Create", locals: { cancel: root_path } %>

形式偏的动态路径？
