如何在Django管理界面中添加用户到#34;更改组"?
我已经看到了肮脏的黑客,以使这适用于较旧的django版本。
如何用Django 1.10解决这个问题?
强调:我希望在页面"更改组"而不是"更改用户"。
我想在django-admin-style中有这个:没有编码,只是做一些配置。也许是这样的:
class GroupAdmin(admin.ModelAdmin):
show_reverse_many_to_many = ('user',)

您需要编写一些代码。请注意,Django管理站点是正常的Django视图和表单!
首先创建一个ModelForm:
otool -TV <object>
nm -a <object>
我们添加了一个自定义的Group ModelForm。第二步是取消注册原始组管理员并注册一个显示我们的ModelForm的新组管理员:
from django import forms
from django.contrib import admin
from django.contrib.auth import get_user_model
from django.contrib.admin.widgets import FilteredSelectMultiple
from django.contrib.auth.models import Group
User = get_user_model()
# Create ModelForm based on the Group model.
class GroupAdminForm(forms.ModelForm):
class Meta:
model = Group
exclude = []
# Add the users field.
users = forms.ModelMultipleChoiceField(
queryset=User.objects.all(),
required=False,
# Use the pretty 'filter_horizontal widget'.
widget=FilteredSelectMultiple('users', False)
)
def __init__(self, *args, **kwargs):
# Do the normal form initialisation.
super(GroupAdminForm, self).__init__(*args, **kwargs)
# If it is an existing group (saved objects have a pk).
if self.instance.pk:
# Populate the users field with the current Group users.
self.fields['users'].initial = self.instance.user_set.all()
def save_m2m(self):
# Add the users to the Group.
self.instance.user_set.set(self.cleaned_data['users'])
def save(self, *args, **kwargs):
# Default save
instance = super(GroupAdminForm, self).save()
# Save many-to-many data
self.save_m2m()
return instance

你必须编写代码来实现你想要的,因为django admin为其中包含M2M字段的模型提供了更改表单,即User
,因为m2m到Group
是在里面那个模特。
所以基本上,在django admin中完成它并且很好,你可能需要覆盖几个函数并提供你自己的实现。
class GroupForm(forms.Form):
blah
users = forms.ModelMultipleChoiceField(
label=_('Users'), required=False, queryset=User.objects.all(),
widget=FilteredSelectMultiple(is_stacked=True, verbose_name=_('Users')),help_text=mark_safe("Help text")
)
class GroupAdmin(BaseAdmin):
form = GroupForm
# you can here define fieldsets to render your form more beautifully
def save_related(self, request, form, formsets, change):
current_group = form.instance
# ....
# Update relations between users and the group here, both are
# accessible with the form instance
def get_changeform_initial_data(self, request):
# If you want to render the form with initial data for the user
# you may optionally override this method as well.
initial = super(GroupAdmin, self).get_changeform_initial_data(request)
initial.update({'users': ...})
return initial
这是我发现实现你想要的最多django-ic方式!希望它有所帮助或给你一个想法

在更改群组页面上,您必须覆盖更改群组表单并添加一个包含用户的多个选择框
