html - Rails 教程第 7 章注册表单错误未显示正确

Question

正在处理失败的注册表单并出现错误，目前它在视觉上看起来不正常，如下图所示:

错误部分周围有一个不应该出现的红色框，每个列表错误旁边都有一个不应该出现的星号，并且由于某种原因密码确认没有错误。此外，所有输入字段都缩小了，并且过度突出显示为红色。

(请注意，为了好玩，我将用户资源更改为狗资源)

这是我的自定义 css.scss

@import "bootstrap";


/* mixins, variables, etc. */

$grayMediumLight: #eaeaea; 

@mixin box_sizing {
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
  box-sizing: border-box;
}

/* universal */

html {
  overflow-y: scroll;
}

body {
  padding-top: 60px;
}

section {
  overflow: auto;
}

textarea {
  resize: vertical;
}

.center {
  text-align: center;
  h1 {
    margin-bottom: 10px;
  }
}


/* typography */

h1, h2, h3, h4, h5, h6 {
  line-height: 1;
}

h1 {
  font-size: 3em;
  letter-spacing: -2px;
  margin-bottom: 30px;
  text-align: center;
}

h2 {
  font-size: 1.2em;
  letter-spacing: -1px;
  margin-bottom: 30px;
  text-align: center;
  font-weight: normal;
  color: $grayLight;
}

p {
  font-size: 1.1em;
  line-height: 1.7em;
}

/* header */

#logo {
  float: left;
  margin-right: 10px;
  font-size: 1.7em;
  color: white;
  text-transform: uppercase;
  letter-spacing: -1px;
  padding-top: 9px;
  font-weight: bold;
  line-height: 1;
  &:hover {
    color: white;
    text-decoration: none;
  }
}
/* footer */

footer {
  margin-top: 45px;
  padding-top: 5px;
  border-top: 1px solid $grayMediumLight;
  color: $grayLight;
  a {
    color: $gray;
    &:hover {
      color: $grayDarker;
    }
  }
  small {
    float: left;
  }
  ul {
    float: right;
    list-style: none;
    li {
      float: left;
      margin-left: 10px;
    }
  }
}

/* sidebar */

aside {
  section {
    padding: 10px 0;
    border-top: 1px solid $grayLighter;
    &:first-child {
      border: 0;
      padding-top: 0;
    }
    span {
      display: block;
      margin-bottom: 3px;
      line-height: 1;
    }
   h1 {
      font-size: 1.4em;
      text-align: left;
      letter-spacing: -1px;
      margin-bottom: 3px;
      margin-top: 0px;
    }
  }
} 

.gravatar {
  float: left;
  margin-right: 10px;
}

/* miscellaneous */

.debug_dump {
  clear: both;
  float: left;
  width: 100%;
  margin-top: 45px;
  @include box_sizing;
}

/* forms */

input, textarea, select, .uneditable-input {
  border: 1px solid #bbb;
  width: 100%;
  margin-bottom: 15px;
  @include box_sizing;
}

input {
  height: auto !important;
}

#error_explanation {
  color: #f00;
  ul {
    list-style: none;
    margin: 0 0 18px 0;
  }
}

.field_with_errors {
  @extend .control-group;
  @extend .error;
}

这是 new.html.erb

<% provide(:title, 'Sign up') %>
<h1>Sign up</h1>

<div class="row">
<div class="span6 offset3">
    <%= form_for(@dog) 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, "Password Confirmation" %>
        <%= f.password_field :password_confirmation %>

        <%= f.submit "Create my account", class: "btn btn-large btn-primary" %>
    <% end %>
</div>

最后是shared/_error_messages.html.erb

<% if @dog.errors.any? %>
  <div id="error_explanation">
    <div class="alert alert-error">
      The form contains <%= pluralize(@dog.errors.count, "error") %>.
    </div>
    <ul>
      <% @dog.errors.full_messages.each do |msg| %>
        <li>* <%= msg %></li>
      <% end %>
    </ul>
  </div>
<% end %>

啊和我的 DogsController 以防万一有帮助(有趣的是，创建操作有一个渲染"new"，但如果我点击带有无效信息的提交按钮，它会被重定向到索引网址(/dogs)，但仍然具有带有错误？教程上也出现了这样的情况，但只是发现作为旁注很有趣。)

class DogsController < ApplicationController
  def new
@dog = Dog.new
  end

  def show
@dog = Dog.find(params[:id])
  end

  def create
@dog = Dog.new(dog_params)
if @dog.save
    redirect_to @dog
else
    render 'new'
end
 end

private

  def dog_params
    params.require(:dog).permit(:name, :email, :password,
                               :password_confirmation)
  end
end

感谢任何帮助，谢谢!

好吧，我通过删除scaffolds.css.scss 中的所有内容来修复它。但不确定这个文件是什么或者代码是如何进入这里的。
