在Django管理中订购多对多字段 [英] Ordering a Many-To-Many field in Django Admin
问题描述
这是我的设置:
from django.contrib.auth.models import User
class产品(models.Model):
...
email_users = models.ManyToManyField(User,null = True,blank = True)
...
[其他地方]
class ProductAdmin admin.ModelAdmin):
/ pre>
list_display =('name','platform')
admin.site.register(Product,ProductAdmin)
我的主要问题是,当我在管理部分查看产品页面时,默认情况下,电子邮件用户的ID不会被排除,我想通过他们的用户名被命令。
从目前为止我已经看到,似乎我需要添加:
mail_users.admin_order_field ='xxxx'
但我不太清楚访问用户名的语法。
解决方案答案w如上述Hao Lian的评论中所提到的,基本上这是需要做的:
class ProductAdminForm(ModelForm):
email_users = forms.ModelMultipleChoiceField(queryset = User.objects.order_by('username'))
class Meta:
model = Product
class ProductAdmin (admin.ModelAdmin):
list_display =('name','platform')
form = ProductAdminForm
admin.site.register(Product,ProductAdmin)
我的需求略有不同,我需要表单.ModelMultipleChoiceField,而提供的答案使用forms.ModelChoiceField()
Here's my setup:
from django.contrib.auth.models import User class Product(models.Model): ... email_users = models.ManyToManyField(User, null=True, blank=True) ...
[elsewhere]
class ProductAdmin(admin.ModelAdmin): list_display = ('name','platform') admin.site.register(Product, ProductAdmin)
My main problem is, when I'm viewing the "Product" page in the admin section, email users are not being being ordered by their ID by default, and I'd like that to be ordered by their username.
From what I've read so far, it seems like I need to be adding:
email_users.admin_order_field = 'xxxx'
But I'm not quite sure what the syntax is to access the username.
解决方案The answer was referred to in Hao Lian's comment above, essentially, this is what needed to be done:
class ProductAdminForm(ModelForm): email_users = forms.ModelMultipleChoiceField(queryset=User.objects.order_by('username')) class Meta: model = Product class ProductAdmin(admin.ModelAdmin): list_display = ('name','platform') form = ProductAdminForm admin.site.register(Product, ProductAdmin)
Mine was slightly different in the sense that I required the forms.ModelMultipleChoiceField, whereas the answer provided used forms.ModelChoiceField()
