Question

我有一个简单的表格。

        <%= simple_form_for @user, html: { multipart: true }, remote: true do |f| %>
         <div class = "UserEditsJS">
          <div class="row">
            <div id = "NoPaddingFormShort" class = "col-lg-6  col-lg-offset-0 col-md-5 col-md-offset-1 col-sm-6 col-sm-6">
              <%= f.text_field :first_name, class: 'form-control-small-short' %>
            </div>
            <div id = "NoPaddingFormShort" class = "col-lg-6  col-md-5  col-sm-6 col-sm-6">
              <%= f.text_field :last_name, class: 'form-control-small-short' %>
            </div>
         </div>
        </div>

更新操作

        def update
         respond_to do |format|
           if @user.update(user_params)
            if @user.save
            flash.now[:success] = "Profile updated"
            format.html { redirect_to @user }
            format.js { render 'business_card'}
           else
             flash.now[:danger] = "There was a problem with your update"
             format.html { redirect_to user_path(@user) }
             format.js 
          end
         end
        end

我正在运行规范

 it "current user tries to delete their first name" do
     put(:update, :id => @user.id, :user => invalid_attributes)
     @user.reload
     expect(response).to redirect_to(@user), format: 'js'
     expect(@user.first_name).to_not eql invalid_attributes[:first_name]
 end

用户模型需要名字。

 1) UsersController User updates current user tries to delete their first name
   Failure/Error: put(:update, :id => @user.id, :user => invalid_attributes)
   ActionController::UnknownFormat:
   ActionController::UnknownFormat
   # ./app/controllers/users_controller.rb:48:in `update'
   # ./spec/controllers/users_controller_spec.rb:58:in `block (3 levels) in <top (required)>'

问题显然是格式

我试过了：

   format.js  { render js: 'business_card'}

和

  format.js  { render 'business_card'}

控制器中的

以及其他几个选项。

用户何时成功更新所有工作的规范，而不是更新失败时的规范。在SO上有很多例子，但似乎没有解决这个具体问题。我确定这是一个单行答案....我只是看不到它。

Answer 1

您可以尝试在请求中设置格式，如下所示： put :update, :id => @user.id, :user => invalid_attributes, format: :js 或设置params hash params = { id: @user.id, user: invalid_attributes, format: :js }并使用此put :update, params

这个参数调用put
