Flask-admin 自定义后台模板


可能有些人不喜欢原始的管理后台,虽然看起来还挺干净简练的,不是我要的样子,可以自定义吗?
答案当然是可以的。
最好是自己通过github下载flask-admin源码,然后自己查看一下后台的源码走向。

通过这张图,我们也可以了解到模板中,最底层的admin/base.html,其他模板都是通过继承去根据宏去改写具体的显示的。
admin/master.html文件里就是直接引用base.html 没有其他的东西:
{% extends admin_base_template %}

如果我们要改写这个后台的模板,是不是我们只要拿到相应的标签就可以改造了,标签主要就是组件及其数据的html,说白就是wTF在后台生成的代码嵌到模板上,当然,你也可以完全改写了,那也就没有必要用flask-admin的意义了。
我们在base.html 里面看到引入两个其他文件:

{% import 'admin/layout.html' as layout with context -%}
{% import 'admin/static.html' as admin_static with context %}

layout.html文件是最关键的布局文件
layout.html 主要是定义了菜单的宏:菜单的icon,菜单的遍历显示,菜单的扩展链接,菜单的提示信息(增删改后的提示信息)
还有一个重要的lib.html文件是一个库文件,预定义一些样式和组件,也是可以直接拿来用的。

在base.html 可以看到:

{% block main_menu %}
<ul class="nav navbar-nav">
  {{ layout.menu() }}
</ul>
{% endblock %}

就是菜单直接嵌入layout.html的菜单,所以我们可以直接改base.html 包括layout.html 也给修改成我们的就是实现后台模板的整体修改。
可以直接在
Template目录建立目录admin,创建mybase.html,mylayout.html
然后注册模板到flask-admin:

admin = Admin(app, name='cleanblog', template_mode='bootstrap3', base_template='admin/mybase.html')

只需要两步就能解决问题,其实还有一步就是你要找到一个合适的模板:
我们可以去https://startbootstrap.com/te... 下载一套自己觉得还可以的bootstrap样式,最好是bootstrap样式的,原因是这样可以减少一些修改设置样式冲突。

我们分几步进行整合

1)寻找模板,并把文件放到static静态目录下:

以startbootstrap-sb-admin-2-gh-pages模板为例:(可以直接百度搜到)
拷贝压缩包的三个目录到static下:dist,js,vendor

2)在template目录建立目录admin并新建文件 mybase.html,和mylayout.html

1.1 mylayout.html
在复制原先的代码进行修改:

{% macro menu(menu_root=None) %}
  {% if menu_root is none %}{% set menu_root = admin_view.admin.menu() %}{% endif %}
  {%- for item in menu_root %}
    {%- if item.is_category() -%}
      {% set children = item.get_children() %}
      {%- if children %}
        {% set class_name = item.get_class_name() %}
        {%- if item.is_active(admin_view) %}
        <li class="active dropdown">
        {% else -%}
        <li class="dropdown">
        {%- endif %}
          <a class="dropdown-toggle" data-toggle="dropdown" href="javascript:void(0)">
            {% if item.class_name %}<span class="{{ item.class_name }}"></span> {% endif %}{{ item.name }}<b class="caret"></b>
          </a>
          <ul class="dropdown-menu">
          {%- for child in children -%}
            {% set class_name = child.get_class_name() %}
            {%- if child.is_active(admin_view) %}
            <li class="active{% if class_name %} {{class_name}}{% endif %}">
            {% else %}
            <li{% if class_name %} class="{{class_name}}"{% endif %}>
            {%- endif %}
              <a href="{{ child.get_url() }}"{% if child.target %} target="{{ child.target }}"{% endif %}>{{ menu_icon(child) }}{{ child.name }}</a>
            </li>
          {%- endfor %}
          </ul>
        </li>
      {% endif %}
    {%- else %}
      {%- if item.is_accessible() and item.is_visible() -%}
        {% set class_name = item.get_class_name() %}
        {%- if item.is_active(admin_view) %}
        <li class="active{% if class_name %} {{class_name}}{% endif %}">
        {%- else %}
        <li{% if class_name %} class="{{class_name}}"{% endif %}>
        {%- endif %}
          <a href="{{ item.get_url() }}"{% if item.target %} target="{{ item.target }}"{% endif %}>{{ menu_icon(item) }}{{ item.name }}</a>
        </li>
      {%- endif -%}
    {% endif -%}
  {% endfor %}
{% endmacro %}

修改为:

{% macro menu(menu_root=None) %}
  {% if menu_root is none %}{% set menu_root = admin_view.admin.menu() %}{% endif %}
  {%- for item in menu_root %}
    {%- if item.is_category() -%}
      {% set children = item.get_children() %}
      {%- if children %}
        {% set class_name = item.get_class_name() %}
        {%- if item.is_active(admin_view) %}
        <li class="active">
        {% else -%}
        <li>
        {%- endif %}
        <a href="#"><i class="fa fa-bar-chart-o fa-fw"></i> {{ item.name }}<span class="fa arrow"></span></a>
        
        <ul class="nav nav-second-level">
          {%- for child in children -%}
            {% set class_name = child.get_class_name() %}
            {%- if child.is_active(admin_view) %}
            <li class="active">
            {% else %}
            <li>
            {%- endif %}
           <a href="{{ child.get_url() }}" {% if child.target %} target="{{ child.target }}"{% endif %}>{{ menu_icon(child) }}{{ child.name }}</a>
            </li>
          {%- endfor %}
          </ul>
        </li>
      {% endif %}
    {%- else %}
      {%- if item.is_accessible() and item.is_visible() -%}
        {% set class_name = item.get_class_name() %}
        {%- if item.is_active(admin_view) %}
        <li class="active{% if class_name %} {{class_name}}{% endif %}">
        {%- else %}
        <li{% if class_name %} class="{{class_name}}"{% endif %}>
        {%- endif %}
        <a href="{{ item.get_url() }}"{% if item.target %} target="{{ item.target }}"{% endif %}><i class="fa fa-dashboard fa-fw"></i> {{ menu_icon(item) }}{{ item.name }}</a>
        </li>
      {%- endif -%}
    {% endif -%}
  {% endfor %}
{% endmacro %}

主要是根据模板的菜单样式进行修改。
修改之后修改
mybase.html 把所有应的base.html 拿过来修改:
{% block head_css %} {% endblock %}
增加

<!-- MetisMenu CSS -->
<link href="{{ url_for('static', filename='vendor/metisMenu/metisMenu.min.css')}}" rel="stylesheet">
<!-- Custom CSS -->
<link href="{{ url_for('static',
filename='dist/css/sb-admin-2.css')}}" rel="stylesheet">
 <!-- Custom Fonts -->
<link href="{{ url_for('static', filename='vendor/font-awesome/css/font-awesome.min.css')}}" rel="stylesheet" type="text/css">

对于body标签下面的代码,全部黏贴来之模板的内容,
在菜单地方黏贴:
{% block menu_links %}
   {{ layout.menu_links() }}
{% endblock %}

在容器的地方黏贴:

<div id="page-wrapper">
 <!--
            <div class="row">
                <div class="col-lg-12">
                  <h1 class="page-header">Dashboard</h1>
                </div>
            </div>
-->
         <div class="row">
          {% block access_control %}
            {% endblock %}
         {% block messages %}
           {{ layout.messages() }}
          {% endblock %}
          {# store the jinja2 context for form_rules rendering logic #}
         {% set render_ctx = h.resolve_ctx() %}
         </div>
         <div class="row">
         {% block body %}{% endblock %}
         </div>
        </div>

最后的代码就如下:

{% import 'admin/mylayout.html' as layout with context -%}
{% import 'admin/static.html' as admin_static with context %}
<!DOCTYPE html>
<html>
  <head>
    <title>{% block title %}{% if admin_view.category %}{{ admin_view.category }} - {% endif %}{{ admin_view.name }} - {{ admin_view.admin.name }}{% endblock %}</title>

        {% endif %}
