Django-如何獲取當前登錄用戶以在django admin中進行填充？

Question

我創建了一個表單，用於在當前登錄用戶進行提交時提交我要在管理員中填充的所有內容，但當前登錄用戶的用戶名除外。

我正在使用的自定義用戶模型位於from users.models import CustomUser如果有幫助。

如何獲取當前登錄用戶的用戶名，以填充user列中的admin.py ？

我很感激任何幫助，干杯

# Register models here.

class UserProfileAdmin(admin.ModelAdmin):
    list_display = ['name', 'address', 'zip_code', 'mobile_number', 'created', 'updated', 'user']
    list_filter = ['name', 'zip_code', 'created', 'updated', 'user']

admin.site.register(Listing, UserProfileAdmin)

的HTML

<form role="form" action="" method="post">
{% csrf_token %}
{{ form.non_field_errors }}
{{ form.errors }}   
{{ form.name }}
{{ form.address }}
{{ form.zip_code }}
{{ form.mobile_number }}
<button class="btn btn-primary btn-success btn-round btn-extend" type="submit" value="Submit"><i class="zmdi zmdi-favorite-outline6"></i>Submit</button>
</form>   

設定

AUTH_USER_MODEL = 'users.CustomUser'

Answer 1

在UserProfileAdmin的list_display中，您可以設置一種方法的名稱，該方法將從引用的user對象中檢索用戶名。

例如，使用名為get_username()的方法：

class UserProfileAdmin(admin.ModelAdmin):
    list_display = ['name', 'address', 'zip_code', 'mobile_number',
                    'created', 'updated', 'get_username']  # Use the method name
    list_filter = ['name', 'zip_code', 'created', 'updated', 'user']

    def get_username(self, obj):
        if obj.user is not None:
            return obj.user.username
        return '-'
    get_username.short_description = 'User'

obj參數是表示表中當前行的Listing實例。

更改了view.py中的以下代碼以解決此問題：

user_profile / views.py

from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import render, redirect
from django.conf import settings
from django.views.generic.edit import FormView
from django.views.generic.edit import UpdateView
from django.views.generic import TemplateView
from .forms import HomeForm
from users.forms import CustomUserCreationForm, CustomUserChangeForm
from .models import Listing
from users.models import CustomUser
from django.urls import reverse_lazy
from django.utils import six
from django.utils.translation import ugettext as _
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from avatar.forms import PrimaryAvatarForm, DeleteAvatarForm, UploadAvatarForm
from avatar.models import Avatar
from avatar.signals import avatar_updated, avatar_deleted
from avatar.utils import (get_primary_avatar, get_default_avatar_url,
                          invalidate_cache)


def change_view(request):
    form = HomeForm(request.POST or None)
    user_profile = Listing.objects.all
    user = request.user

    if form.is_valid():
        listing_instance = form.save()  # "this will return the 'Listing' instance"
        listing_instance.user = user
        listing_instance.save()
        form = HomeForm()

    context = {
        'form': form, 'user_profile': user_profile
    }

    return render(request, "myaccount.html", context)
