Question

我无法 respond_to 使用 format.js 。

class UserSessionsController < UserApplicationController
  def create
    if @counterparty
      session[:counterparty_id] = @counterparty.id
      @counterparty.update(signed_in: true)
    else
      flash.now[:error] = 'Invalid email or password'
    end

    respond_to do |format|
      format.js
      format.json { render json: @counterparty }
    end
  end
end

视图/ user_sessions / create.js.erb

alert("Please, notice me!")

这是怎么回事？

现在，关于它的最有趣的部分！

如果我这样，我的警报会显示，但该选项不适合我。

class UserSessionsController < UserApplicationController
 respond_to :js, only: :create

  def create
    if @counterparty
      session[:counterparty_id] = @counterparty.id
      @counterparty.update(signed_in: true)
    else
      flash.now[:error] = 'Invalid email or password'
    end

    respond_with(@counterparty, layout: false)
  end
end

application.html.slim

doctype html
html
  head
    title ActiveAccounting
    = javascript_include_tag 'application', 'data-turbolinks-track' => true
    = stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true
    = csrf_meta_tags
    link href="favicon.ico" rel=("shortcut icon") type="image/x-icon" /
  body
    = render 'shared/flash'
    = yield

我该怎么办？

Answer 1

您的js模板在应用程序布局中呈现。您可以通过以下方式阻止：

 format.js { render layout: false }

或通过更全面的解决方案：

class ApplicationController < ActionController::Base
  layout proc{|c| c.request.xhr? ? false : "application" }
end

Respond_to阻止无效
