Question

我在会话视图中自定义事物默认设置new.html.erb，因此它生成像

这样的Html代码

  <form class="form-signin" role="form">
    <h2 class="form-signin-heading">Please sign in</h2>
    <input type="text" class="form-control" placeholder="Email address" required autofocus>
    <input type="password" class="form-control" placeholder="Password" required>
    <label class="checkbox">
      <input type="checkbox" value="remember-me"> Remember me
    </label>
    <button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
  </form>

我添加了以下行：html =＆gt; {:class => 'form-signin', :role => 'form'}代码如下。

<%= form_for(resource, :as => resource_name, :url => session_path(resource_name),
    :html => {:class => 'form-signin', :role => 'form'}) do |f| %>
  <div><%= f.label :email %><br />
  <%= f.email_field :email  %></div>
  <div><%= f.label :password %><br />
  <%= f.password_field :password %></div>

  <% if devise_mapping.rememberable? -%>
    <div><%= f.check_box :remember_me %> <%= f.label :remember_me %></div>
  <% end -%>

  <div><%= f.submit "Sign in" %></div>
<% end %>

<%= render "devise/shared/links" %>

我不知道接下来要做什么来修改

<div><%= f.label :email %><br />
  <%= f.email_field :email  %></div>

所以它生成了这个：<input type="text" class="form-control" placeholder="Email address" required autofocus>

?? 谢谢！

Answer 1

<%= f.text_field :email, placeholder: "Email address",
required: true, autofocus: true  %>

应该工作。
