杀手级xadmin开发在线教育网站8-4_xadmin快速配置列表、搜索、过滤等功能

xadmin中注册自己的Model

• 在app中新建adminx.py
• 编辑文件

import xadmin

from apps.courses.models import Course


# xadmin允许我们不继承任何东西
class CourseAdmin(object):
    pass


xadmin.site.register(Course, CourseAdmin)

• app显示中文

修改apps.py

from django.apps import AppConfig


class CoursesConfig(AppConfig):
    name = 'apps.courses'
    verbose_name = '课程管理'

• 添加课程信息，需要添加老师+机构+城市的信息（老师里面也需要先添加机构信息，机构信息依赖城市信息）

• 把机构app也注册进来（老师+机构+城市）

修改 apps/organizations/adminx.py

import xadmin

from apps.organizations.models import Teacher, CourseOrg, City


# xadmin允许我们不继承任何东西
class TeacherAdmin(object):
    pass


class CourseOrgAdmin(object):
    pass


class CityAdmin(object):
    pass


xadmin.site.register(Teacher, TeacherAdmin)
xadmin.site.register(CourseOrg, CourseOrgAdmin)
xadmin.site.register(City, CityAdmin)

• 添加城市信息，返回的信息看不懂，所以要重写__str__方法

• 修改机构models

from django.db import models
from apps.users.models import BaseModel


class City(BaseModel):
    name = models.CharField(max_length=20, verbose_name='城市')
    desc = models.CharField(max_length=200, verbose_name='描述')

    class Meta:
        verbose_name = '城市'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name


class CourseOrg(BaseModel):
    name = models.CharField(max_length=50, verbose_name='机构名称')
    desc = models.TextField(verbose_name='描述')
    tag = models.CharField(default='全国知名', max_length=10, verbose_name='机构标签')
    category = models.CharField(default='pxjp', verbose_name='机构类别', max_length=4,
                                choices=(('pxjg', '培训机构'), ('gr', '个人'), ('gx', '高校')))

    click_nums = models.IntegerField(default=0, verbose_name='点击数')
    fav_nums = models.IntegerField(default=0, verbose_name='收藏数')
    image = models.ImageField(upload_to='org/%Y/%m', verbose_name='logo', max_length=100)
    address = models.CharField(max_length=150, verbose_name="机构地址")
    students = models.IntegerField(default=0, verbose_name="学习人数")
    course_nums = models.IntegerField(default=0, verbose_name="课程数")
    city = models.ForeignKey(City, on_delete=models.CASCADE, verbose_name='所在城市')

    class Meta:
        verbose_name = '课程机构'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name


class Teacher(BaseModel):
    org = models.ForeignKey(CourseOrg, on_delete=models.CASCADE, verbose_name="所属机构")
    name = models.CharField(max_length=50, verbose_name="教师名")
    work_years = models.IntegerField(default=0, verbose_name="工作年限")
    work_company = models.CharField(max_length=50, verbose_name="就职公司")
    work_position = models.CharField(max_length=50, verbose_name="公司职位")
    points = models.CharField(max_length=50, verbose_name="教学特点")
    click_nums = models.IntegerField(default=0, verbose_name="点击数")  # 人气排序用
    fav_nums = models.IntegerField(default=0, verbose_name="收藏数")
    age = models.IntegerField(default=18, verbose_name="年龄")
    image = models.ImageField(upload_to="teacher/%Y/%m", verbose_name="头像", max_length=100)

    class Meta:
        verbose_name = '教师'
        verbose_name_plural = verbose_name

    def __str__(self):
        return self.name

现在显示就正常了

• 定制页面的功能

1.显示列内容 list_display

class CityAdmin(object):
    list_display = ['id', 'name', 'desc']

2.搜索的字段 search_fields

class CityAdmin(object):
    list_display = ['id', 'name', 'desc']
    search_fields = ['name', 'desc']

3.过滤的字段 list_filter

class CityAdmin(object):
    list_display = ['id', 'name', 'desc']
    search_fields = ['name', 'desc']
    list_filter = ['name', 'desc', 'add_time']

4.在列表页直接修改字段 list_editable
数据很大的时候这个就显的很方便了

class CityAdmin(object):
    list_display = ['id', 'name', 'desc']
    search_fields = ['name', 'desc']
    list_filter = ['name', 'desc', 'add_time']
    list_editable = ['name', 'desc']
