Django Admin-禁用特定模型的“添加”操作

很容易,只是超载 has_add_permission 你的方法 Admin

class MyAdmin(admin.ModelAdmin):
     def has_add_permission(self, request, obj=None):
        return False

默认情况下,syncdb为每个模型创建3个安全权限:

2. 改变
3. 删除

如果您以管理员身份登录,则 不管怎样。

但是如果你创造了一个新的 用户组 打电话 然后,您只能为所有模型分配更改和删除权限。

我想这对你有帮助。。 下面的代码必须在admin.py文件中

@admin.register(Author)
class AuthorAdmin(admin.ModelAdmin):
    list_display = ('name', )
    list_filter = ('name', )
    search_fields = ('name', )
    list_per_page = 20

    # This will help you to disbale add functionality
    def has_add_permission(self, request):
        return False

    # This will help you to disable delete functionaliyt
    def has_delete_permission(self, request, obj=None):
        return False

# In admin
# make the related field can't be added
    def get_form(self, request, obj=None, **kwargs):
        form = super().get_form(request, obj, **kwargs)
        form.base_fields['service'].widget.can_add_related = False
        return form

在我的例子中,我使用内联

# In inline formset e.g. admin.TabularInline
# disable all
    def get_formset(self, request, obj=None, **kwargs):
        formset = super().get_formset(request, obj, **kwargs)
        service = formset.form.base_fields['service']
        service.widget.can_add_related = service.widget.can_change_related = service.widget.can_delete_related = False
        return formset

在里面 service = formset.form.base_fields['service'] base_fields

如果在表单中定义,请使用:

product = formset.form.declared_fields['product']

这是一个太多的延迟回答;只是张贴这个似乎有人正在寻找相同的解决方案。

class MyModelForm(forms.ModelForm):

class Meta:
    model = MyModel
    fields = '__all__'


class MyModelAdmin(admin.ModelAdmin):
    form = QuestionTrackAdminForm
    list_display = ['title', 'weight']
    readonly_fields = ['title', 'weight']

admin.site.register(MyModel, MyModelAdmin)

在这里,“只读字段”起到了神奇的作用。谢谢。
