极客教程定制Django管理界面
Django admin默认是高度响应的GUI，它提供了各种功能和整体的CRUD应用来帮助开发者和用户。此外，Django管理员可以根据自己的需要进行定制，比如在表格的首页显示字段等。在这篇文章中，我们将讨论如何增强Django-admin界面。
项目结构看起来像。
让我们创建一个名为state的应用程序，它有一个同名的模型（state）。当我们在admin.py中注册应用程序时，它显示如下。
state/model.py
from django.db import models
from django.utils import timezone
class State(models.Model):
name = models.CharField(max_length = 50)
is_active = models.IntegerField(default = 1,
blank = True,
null = True,
help_text ='1->Active, 0->Inactive',
choices =(
(1, 'Active'), (0, 'Inactive')
))
created_on = models.DateTimeField(default = timezone.now)
updated_on = models.DateTimeField(default = timezone.now,
null = True,
blank = True
)
def __str__(self):
return self.name
class Meta:
db_table = 'state'
state/admin.py:
from django.contrib import admin
from .models import State
admin.site.register(State)
在django管理界面中检查它
现在让我们根据可用的选项来定制django admin。
定制Django管理界面
1.改变模型名称:
如果你想改变这里的模型名称，请打开model.py文件，在meta部分添加verbose_name属性。
state/model.py
from django.db import models
from django.utils import timezone
class State(models.Model):
name = models.CharField(max_length = 50)
is_active = models.IntegerField(default = 1,
blank = True,
null = True,
help_text ='1->Active, 0->Inactive',
choices =(
(1, 'Active'), (0, 'Inactive')
))
created_on = models.DateTimeField(default = timezone.now)
updated_on = models.DateTimeField(default = timezone.now,
null = True,
blank = True
)
def __str__(self):
return self.name
class Meta:
db_table = 'state'
# Add verbose name
verbose_name = 'State List'
输出 :
2.默认情况下，django管理员在列表中只显示对象名称。
人们可以从模型中显示多个字段的数据。在你的admin.py文件中添加几行代码。
state/admin.py:
from django.contrib import admin
from .models import State
class StateAdmin(admin.ModelAdmin):
list_display = ('name', 'active', 'created_on')
def active(self, obj):
return obj.is_active == 1
active.boolean = True
admin.site.register(State, StateAdmin)
输出 :
3.默认情况下，只有一个选项，即删除选项。
人们可以在行动下拉菜单上添加更多的选项。
state/admin.py:
from django.contrib import admin
from django.contrib import messages
from .models import State
class StateAdmin(admin.ModelAdmin):
list_display = ('name', 'active', 'created_on')
def active(self, obj):
return obj.is_active == 1
active.boolean = True
def make_active(modeladmin, request, queryset):
queryset.update(is_active = 1)
messages.success(request, "Selected Record(s) Marked as Active Successfully !!")
def make_inactive(modeladmin, request, queryset):
queryset.update(is_active = 0)
messages.success(request, "Selected Record(s) Marked as Inactive Successfully !!")
admin.site.add_action(make_active, "Make Active")
admin.site.add_action(make_inactive, "Make Inactive")
admin.site.register(State, StateAdmin)
输出:
4.禁用删除选项:
state/admin.py:
from django.contrib import admin
from django.contrib import messages
from .models import State
class StateAdmin(admin.ModelAdmin):
list_display = ('name', 'active', 'created_on')
def active(self, obj):
return obj.is_active == 1
active.boolean = True
def make_active(modeladmin, request, queryset):
queryset.update(is_active = 1)
messages.success(request, "Selected Record(s) Marked as Active Successfully !!")
def make_inactive(modeladmin, request, queryset):
queryset.update(is_active = 0)
messages.success(request, "Selected Record(s) Marked as Inactive Successfully !!")
admin.site.add_action(make_active, "Make Active")
admin.site.add_action(make_inactive, "Make Inactive")
def has_delete_permission(self, request, obj = None):
return False
admin.site.register(State, StateAdmin)
输出:
5.禁用添加选项:
state/admin.py:
from django.contrib import admin
from .models import State
class StateAdmin(admin.ModelAdmin):
list_display = ('name', 'active', 'created_on')
def active(self, obj):
return obj.is_active == 1
active.boolean = True
def has_add_permission(self, request):
return False
admin.site.register(State, StateAdmin)
