ModelAdmin methods

 

 

设置方法

 

注意save_model和delete_model不容许进行额外的操作

 

class ArticleAdmin(admin.ModelAdmin):

    def save_model(self, request, obj, form, change):

        obj.user = request.user

        obj.save()

 

For example to attach request.user to each changed formset model instance:

class ArticleAdmin(admin.ModelAdmin):

    def save_formset(self, request, form, formset, change):

        instances = formset.save(commit=False)

        for instance in instances:

            instance.user = request.user

            instance.save()

        formset.save_m2m()

自定义排序

 

class PersonAdmin(ModelAdmin):



    def get_ordering(self, request):

        if request.user.is_superuser:

            return ['name', 'rank']

        else:

            return ['name']

 

 

 

ModelAdmin. save_related( self,  request,  form,  formsets,  change)

New in Django 1.4.

The save_related method is given the HttpRequest, the parent ModelForm instance, the list of inline formsets and a boolean value based on whether the parent is being added or changed. Here you can do any pre- or post-save operations for objects related to the parent. Note that at this point the parent object and its form have already been saved.

ModelAdmin. get_readonly_fields( self,  request,  obj=None)

The get_readonly_fields method is given the HttpRequest and the obj being edited (or None on an add form) and is expected to return a list or tuple of field names that will be displayed as read-only, as described above in the ModelAdmin.readonly_fieldssection.

ModelAdmin. get_prepopulated_fields( self,  request,  obj=None)

New in Django 1.4.

The get_prepopulated_fields method is given the HttpRequest and the obj being edited (or None on an add form) and is expected to return a dictionary, as described above in the ModelAdmin.prepopulated_fields section.

ModelAdmin. get_list_display( self,  request)

New in Django 1.4.

The get_list_display method is given the HttpRequest and is expected to return a list or tuple of field names that will be displayed on the changelist view as described above in the ModelAdmin.list_display section.

ModelAdmin. get_list_display_links( self,  request,  list_display)

New in Django 1.4.

The get_list_display_links method is given the HttpRequest and the list or tuple returned by ModelAdmin.get_list_display(). It is expected to return a list or tuple of field names on the changelist that will be linked to the change view, as described in theModelAdmin.list_display_links section.

ModelAdmin. get_fieldsets( self,  request,  obj=None)

The get_fieldsets method is given the HttpRequest and the obj being edited (or None on an add form) and is expected to return a list of two-tuples, in which each two-tuple represents a <fieldset> on the admin form page, as described above in theModelAdmin.fieldsets section.

ModelAdmin. get_list_filter( self,  request)

New in Django 1.5.

The get_list_filter method is given the HttpRequest and is expected to return the same kind of sequence type as for thelist_filter attribute.

ModelAdmin. get_inline_instances( self,  request,  obj=None)

New in Django 1.5.

The get_inline_instances method is given the HttpRequest and the obj being edited (or None on an add form) and is expected to return a list or tuple of InlineModelAdmin objects, as described below in the InlineModelAdmin section.

ModelAdmin. get_urls( self)

The get_urls method on a ModelAdmin returns the URLs to be used for that ModelAdmin in the same way as a URLconf. Therefore you can extend them as documented in URL dispatcher:

class MyModelAdmin(admin.ModelAdmin):

    def get_urls(self):

        urls = super(MyModelAdmin, self).get_urls()

        my_urls = patterns('',

            (r'^my_view/$', self.my_view)

        )

        return my_urls + urls



    def my_view(self, request):

        # custom view which should return an HttpResponse

        pass

Note

Notice that the custom patterns are included before the regular admin URLs: the admin URL patterns are very permissive and will match nearly anything, so you’ll usually want to prepend your custom URLs to the built-in ones.

In this example, my_view will be accessed at /admin/myapp/mymodel/my_view/ (assuming the admin URLs are included at /admin/.)

However, the self.my_view function registered above suffers from two problems:

• It will not perform any permission checks, so it will be accessible to the general public.
• It will not provide any header details to prevent caching. This means if the page retrieves data from the database, and caching middleware is active, the page could show outdated information.

Since this is usually not what you want, Django provides a convenience wrapper to check permissions and mark the view as non-cacheable. This wrapper is AdminSite.admin_view() (i.e. self.admin_site.admin_view inside a ModelAdmin instance); use it like so:

class MyModelAdmin(admin.ModelAdmin):

    def get_urls(self):

        urls = super(MyModelAdmin, self).get_urls()

        my_urls = patterns('',

            (r'^my_view/$', self.admin_site.admin_view(self.my_view))

        )

        return my_urls + urls

Notice the wrapped view in the fifth line above:

(r'^my_view/$', self.admin_site.admin_view(self.my_view))

This wrapping will protect self.my_view from unauthorized access and will apply the django.views.decorators.cache.never_cachedecorator to make sure it is not cached if the cache middleware is active.

If the page is cacheable, but you still want the permission check to be performed, you can pass a cacheable=True argument to AdminSite.admin_view():

(r'^my_view/$', self.admin_site.admin_view(self.my_view, cacheable=True))

以上为原版内容，不在讲解

 

 

def get_form(self, request, obj=None, **kwargs):

        self.exclude = []

        if not request.user.is_superuser:

            self.exclude.append('field_to_hide')

        return super(MyModelAdmin, self).get_form(request, obj, **kwargs)

设置不同用户登录，使用不同的权限视图

 

 

class MyModelAdmin(admin.ModelAdmin):

    inlines = [MyInline, SomeOtherInline]



    def get_formsets(self, request, obj=None):

        for inline in self.get_inline_instances(request, obj):

            # hide MyInline in the add view

            if isinstance(inline, MyInline) and obj is None:

                continue

            yield inline.get_formset(request, obj)

 

 

设置含有inlines的权限视图

 

class MyModelAdmin(admin.ModelAdmin):

    def formfield_for_foreignkey(self, db_field, request, **kwargs):

        if db_field.name == "car":

            kwargs["queryset"] = Car.objects.filter(owner=request.user)

        return super(MyModelAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs)

外键过滤

 

 

class MyModelAdmin(admin.ModelAdmin):

    def formfield_for_manytomany(self, db_field, request, **kwargs):

        if db_field.name == "cars":

            kwargs["queryset"] = Car.objects.filter(owner=request.user)

        return super(MyModelAdmin, self).formfield_for_manytomany(db_field, request, **kwargs)

多余多过滤

 

一下为不同权限设置不同的choices

 

class MyModelAdmin(admin.ModelAdmin):

    def formfield_for_choice_field(self, db_field, request, **kwargs):

        if db_field.name == "status":

            kwargs['choices'] = (

                ('accepted', 'Accepted'),

                ('denied', 'Denied'),

            )

            if request.user.is_superuser:

                kwargs['choices'] += (('ready', 'Ready for deployment'),)

        return super(MyModelAdmin, self).formfield_for_choice_field(db_field, request, **kwargs)

 

 

 

class MyForm(forms.ModelForm):

    class Meta:

        model = MyModel



class MyModelAdmin(admin.ModelAdmin):

    def get_changelist_form(self, request, **kwargs):

        return MyForm

自定义form，并且引入
