Rails 3：未定义的方法`remote_form_for'

I have a fairly simple Rails remote form in HAML in a partial under shared/users:

我在HAML中有一个相当简单的Rails远程表单，部分在共享/用户之下：

- remote_form_for :user, :url => { :controller => "users", :action => "create" } do |f|
  .field
    = f.label :name, t('name')
    = f.text_field :name
  .field
    = f.label :email, t('email')
    = f.text_field :email
  .actions
    = f.submit

No matter how much I fiddle with it, this just won't work. I alway get the following error:

无论我多么愚弄它，这都行不通。我总是得到以下错误：

undefined method `remote_form_for' for #<#<Class:0x1036e8e40>:0x1036dfd90>

Am I doing something stupid? It works perfectly with form_for.

我做了些蠢事吗？它与form_for完美配合。

2 个解决方案

#1

remote_form_for no longer exists.

remote_form_for不再存在。

Try adding

尝试添加

:remote => true

as an option to form_for

作为form_for的选项

form_for :user, :remote => true, :url => { :controller => "users", :action => "create" } do |f|

see: http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-form_for

请参阅：http：//api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-form_for

#2

It's because this method is delete on Rails 3

这是因为这个方法在Rails 3上被删除了

Use now

现在使用

form_for ..., :remote => true

Your code becomes :

您的代码变为：

- form_for :user, :url => { :controller => "users", :action => "create" }, :remote => true do |f|
  .field
    = f.label :name, t('name')
    = f.text_field :name
  .field
    = f.label :email, t('email')
    = f.text_field :email
  .actions
    = f.submit

And you need the rails.jquery.js or same in prototype to use it. It's the UJS improvement in rails.

并且您需要rails.jquery.js或原型中的相同才能使用它。这是UJS在铁轨方面的改进。
