Question

您从外部来源提交form_for时遇到2个问题。我正在使用Jquery ajax。它是一个窗口小部件的一个窗体，当用户在网站上添加代码时添加它（js）

这是我正在使用的Haml代码

    = form_for [@deck.user, @deck, @deck.recipients.new], html: { id: "emailform" }, remote: true do |f|
      = f.text_field :sender_name, placeholder: "Your name"
      = f.label :sender_name, "Your name", class: "name-label"

      = f.text_field :email, placeholder: "Email of your friend"
      = f.label :email, "Email of your friend", class: "email-label"
      .email-send#submit
        = f.submit(type: "image", alt: "send email", src: image_url("widget/email.png"))

问题1：它在主站点上没有问题。但它应该将我们网站的根网址添加到路径中怎么做？

问题2：当我手动添加根URL并测试它时，它会返回以下错误：格式未知这可能是因为它试图提交html而不是js格式。怎么解决？

Answer 1

尝试类似

的内容

= form_for [@deck.user, @deck, @deck.recipients.new], html: { id: "emailform" }, remote: true, url: root_url_of_main_site , format: :js do |f|

root_url_of_main_site可以很容易地成为一个字符串，因为显然这个表单是由另一个rails应用程序在另一个中呈现的

Answer 2

= form_for @deck.user, url: something_url , id: "emailform", remote: true do |f|
    = f.text_field :sender_name, placeholder: "Your name"
    = f.label :sender_name, "Your name", class: "name-label"
    = f.text_field :email, placeholder: "Email of your friend"
    = f.label :email, "Email of your friend", class: "email-label"
    .email-send#submit
        = f.submit(type: "image", alt: "send email", src: image_url("widget/email.png"))

something_url是您要将表单提交到的路径。您最有可能想使用命名路由帮助程序。

嵌套超过2个级别的网址往往非常繁琐，并导致一堆令人困惑的依赖问题。

resources :users, shallow: true do
  resources :decks
end

resources :decks, only: [], shallow: true do
  resources :recipients
end

                   PATCH  /recipients/:id(.:format)                recipients#update
                   PUT    /recipients/:id(.:format)                recipients#update
                   DELETE /recipients/:id(.:format)                recipients#destroy

这可让我们发布到deck_recipients_url(deck_id: @deck)

Ruby on Rails form_for作为绝对url
