类以的form_for Ruby on Rails的

Question

我不明白为什么这回我一个错误

<%= form_for(@user), :html => {:class => 'form-connexion'} do |f| %> 
    <%= render 'shared/error_messages' %> 

    <%= f.label :name %> 
    <%= f.text_field :name %> 

    <%= f.label :email %> 
    <%= f.text_field :email %> 

    <%= f.label :password %> 
    <%= f.password_field :password %> 

    <%= f.label :password_confirmation, "Confirm Password" %> 
    <%= f.password_field :password_confirmation %> 

    <%= f.submit "Save changes", class: "btn btn-large btn-primary" %> 
<% end %>

Answer 1

form_for(@user), :html => ... 

那一端的支架，@user后，关闭通话的方法#form_for，所以它不知道如何处理逗号，然后哈希做。

修改成：

form_for(@user, :html => ...) do |f| 

而且你会好。甚至没有括号：

form_for @user, :html => ... do |f|
