django创建项目

Posted 2021-01-07 themost

1、运行django的指令：python manage.py runserver

2、创建项目 django-admin.py startproject mesite

3、创建应用 django-admin.py startapp blog

4、注册应用   settings INSTALLED_APPS

5、根据数据库模型建立数据库表文件(相当于生成sql语句) python manage.py makemigrations 创建数据库表 python manage.py migrate

6、创建超级管理员 python manage.py createsuperuser 登录: 127.0.0.1:8000/admin

7、带环境的shell python manage.py shell

8、获取BookInfo.objects.all() BookInfo.objects.get(pk=1)

9、把模型类注册到admin管理界面 admin.site.register(BookInfo)

10、fields和fieldsets是一个东西 保留一个就可以了

class BookInfoAdmin(admin.ModelAdmin):
    # 列表页
    #显示字段 点击列头可排序
    list_display = ["pk", "btitle", ‘bpub_date‘]
    #过滤字段，过滤框会出现在右侧
    list_filter = ["btitle"]
    #搜索字段，搜索框会出现在上侧
    search_fields = [‘btitle‘]
    #分页， 分页框出现在下侧
    list_per_page = 5
    #修改页和添加页
    # 属性分组
    fieldsets = [
        (u"基础信息", {"fields": [‘btitle‘]}),
        (u"时间信息", {"fields": [‘bpub_date‘]}),
                 ]

class HeroInfoAdmin(admin.ModelAdmin):
    list_display = ["hname", "hgender", "hcontent", "hbook"]
    list_filter = ["hname"]
    search_fields = ["hname"]
    list_per_page = 5
    fieldsets = [
        ("base", {"fields": [‘hname‘, ‘hgender‘]}),
        ("more", {"fields": [‘hcontent‘, ‘hbook‘]}),
                 ]

admin.site.register(BookInfo, BookInfoAdmin)
admin.site.register(HeroInfo, HeroInfoAdmin)


11、关联注册

class HeroInfoInline(admin.TabularInline):
    model = HeroInfo
    extra = 3

class BookInfoAdmin(admin.ModelAdmin):
    inlines = [HeroInfoInline]


12、路由

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r‘^admin/‘, include(admin.site.urls)),
    url(r‘^‘, include(‘booktest.urls‘)),
]
