计算每个用户已上传和批准的文件
Count files each user has uploaded and approved
我正在构建一个用于上传文件的 Django 应用程序。我希望能够计算用户拥有的文件数量和批准的文件数量。我有一个带有布尔 'approved' 字段的模型。此模型在 admin.py。
在admin.py
from django.contrib import admin
from .models import FileModel
from .forms import FileForm
class FileModelAdmin(admin.ModelAdmin):
form = FileForm
fields = ('title', 'description', 'categories', 'pub_date', 'submitted_date', 'author', 'user', 'approved', 'upload', 'vote')
# pass
list_display = ['title', 'approved', 'author', 'user', 'categories', 'description', 'pub_date', 'submitted_date', 'upload', 'vote']
admin.site.register(FileModel, FileModelAdmin)
我想要另一个应用程序中的另一个模型 'new_user_model' 中的整数，以便在管理站点批准文件时将整数字段 'files' 增加一个。这样我就可以跟踪每个用户批准了多少文件。
class NewUserModel(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
# user = models.ForeignKey(User)
files = models.IntegerField(default=0)
文件的模型，
class FileModel(models.Model):
title = models.CharField(max_length=100)
description = models.CharField(max_length=255)
pub_date = models.DateTimeField('date published')
submitted_date = models.DateTimeField('date submitted')
author = models.CharField(max_length=255)
user = models.ForeignKey(User, default=6)
approved = models.BooleanField(default=False)
upload = models.FileField().....................
...................................................
所以我希望 new_user_model 中的文件字段在文件为 'approved' 并且在管理站点中点击保存按钮时增加 1。此外，如果 'approved' 未选中，我需要 'files' 字段减少一个。
这是怎么做到的？
已更新：
最终我希望能够显示用户在站点上拥有的文件数。
谢谢，
您可以添加一个 custom admin action 来将文件标记为已批准。这些被传递给一个请求对象，您可以使用它来获取您的 NewUserModel。 （您可能想从您的模型名称中删除 'Model'，这似乎有点多余，但我想是个人品味 :)
class FileModelAdmin(admin.ModelAdmin):
form = FileForm
fields = ('title', 'description', 'categories', 'pub_date', 'submitted_date', 'author', 'user', 'approved', 'upload', 'vote')
# ....
actions = ['approve_files']
def approve_files(self, request, queryset):
# Queryset can be greater than 1
queryset.update(approved=True)
user = request.user
# I keep wanting to put underscores in...
user_files_count = user.newusermodel.files
# Get the amount of Files in the query, may be more than one
user.newusermodel.files = user_files_count + queryset.count()
user.newusermodel.save()
话虽如此，如果您确实想跟踪谁批准了什么：
class FileModel(models.Model):
title = models.CharField(max_length=100)
# ...
approved_by = models.ForeignKey('auth.User')
那么上面的管理操作就是：
def approve_files(self, request, queryset):
# Queryset can be greater than 1
queryset.update(approved_by=request.user)
您可以通过以下方式获取用户的文件数：
user = Users.objects.get(id=some_id)
file_count = user.filemodel.all().count()
我终于有机会完成这个了？
