Python Django admin many-to-many 多选框改成复选框

在django 的admin中，若有两张表为many-to-many的关系，则使用django model类里面的ManyToManyField了。并且可以选择自定义中间表，在ManyToManyField里面添加属性through=“中间表的model类”。嘿嘿，脱离话题了，下面进入主题吧。

models.py

class Person(models.Model):
name = models.CharField(primary_key=True, max_length=128)
desc = models.CharField(max_length=256)

def __unicode__(self):
return self.name
class Meta:
db_table = u'person'

class Group(models.Model):
name = models.CharField(max_length=128)
members = models.ManyToManyField(Person, db_table='person_group')

def __unicode__(self):
return self.name
class Meta:
db_table = u'group'

admin.py

class GroupForm(forms.ModelForm):
members = forms.ModelMultipleChoiceField(widget=CheckboxSelectMultiple, queryset=Person.objects.all())

class Meta:
model = Group

class GroupAdmin(admin.ModelAdmin):
form = GroupForm

下面是效果图：



个人认为比默认的多选框强，需要的就拿去吧。
