Question

我不明白为什么这会给我一个错误

<%= 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 %>

D:/xxxxxxx/app/views/users/edit.html.erb:7: syntax error, unexpected =>, expecting keyword_end ...end= form_for(@user), :html => {:class => 'form-connexion'}... ... ^

我在另一个文件中使用相同的语法，但没关系。

Answer 1

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

该结束括号在@user之后关闭方法#form_for的调用，因此它不知道如何处理逗号，然后是哈希。

将其更改为：

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

你会好的。甚至没有括号：

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

类到form_for Ruby on Rails
