Rails，嵌套资源控制器在渲染编辑时生成非restful url

Question

我还是有点新手，但是我看到了奇怪的行为，并想知道这是不是常规或者我做错了什么。

我有以下嵌套资源：

resources :accounts do
  resources :users
end

他们正在生成标准的restful url（host.com/accounts/my-account-name/users/33/edit），除非用户的UPDATE失败（例如由于验证）。然后它生成一个url，如host.com/accounts/22/users/22，或者基本上是host.com/accounts/:user_id/users/:user_id

这里发生了什么？该应用程序仍将更新用户，但我不明白为什么这样做。任何帮助或理解表示赞赏。

用户控制器如下：

def update
  respond_to do |format|
    if @user.update(user_params)
      format.html{
        redirect_to account_users_path(@user.account),
                    notice: 'User was successfully updated.'
      }
    else
      format.html { render :edit }
    end
  end
end 

这是我的表格：

.card
        .header Edit User
        .content
          = form_for(@user, url: account_user_path(@user), html: {class: 'form-horizontal'}) do |f|
            .content
              - if @user.errors.any?
                .alert.alert-danger
                  h4 = "#{pluralize(@user.errors.count, 'error')} prohibited the user from being saved."
                  == @user.errors.full_messages.map{|msg| content_tag(:li, msg)}.join
              .form-group
                = f.label :name, class: 'control-label col-lg-2'
                .col-lg-10
                  = f.text_field :name, {placeholder: 'Name', autofocus: true,class: 'form-control'}
              .form-group
                = f.label :email, class: 'control-label col-lg-2'
                .col-lg-10
                  = f.email_field :email, {placeholder: 'Email', class: 'form-control'}
              .form-group
                = label_tag "user[role]", "Role", class: 'control-label col-lg-2'
                .col-lg-10
                  = select_tag "user[role]", options_for_select(@choices,@user.roles.first.name), class:'form-control'
            .footer style ="height: 55px;"
              span.pull-left
                = link_to 'Cancel', account_users_path, class: 'btn btn-primary btn-warning'
              span.pull-right
                =f.submit "Save", class: 'btn btn-primary'
            .footer style ="height: 55px;"
              - if current_user.has_role?(:owner, current_account)
                span.pull-right
                  = link_to 'Delete', account_user_path(@user), {method: :delete, data: {confirm: 'Are you sure?'},
                          class: 'btn btn-danger'} unless @user.id == current_user.id

我不知道是什么问题，据我所知，你的嵌套路线工作正常： - 让我解释一下

当你运行rake routes | grep users

get   'accounts/my-account-name/users/:user_id/edit',to: 'users#edit'
put   'accounts/:account_id/users/:user_id', to: 'users#update'
patch 'accounts/:account_id/users/:user_id', to: 'users#update'

所以这里为你需要通过url和控制器传递account_id所需的每一个动作，你需要在任何动作之前设置@account。你可以在users controller这样做

before_action: get_account
private
  def get_account
    @account = Account.find(params[:id])
  end

并为您的edit_form传递第一个参数作为account对象和user对象，并指定更新操作的方法类型

= form_for(@user, url: account_user_path(@account,@user), html: {class: 'form-horizontal', method: :patch}) do |f|
