计数每个用户上传和批准的文件 [英] Count files each user has uploaded and approved
问题描述
我正在构建一个用于上传文件的Django应用程序。我想能够统计用户拥有的文件数量以及哪些文件被批准。我有一个具有布尔已批准字段的模型。此模型位于admin.py中。
在admin.py
$来自django.contrib的从.models导入FileModel
.forms import FileForm
class FileModelAdmin（ admin.ModelAdmin）：
form = FileForm
fields =（'title'，'description'，'categories'，'pub_date'，'submitted_date'，'author'，'user' ，'upload'，'vote'）
＃pass
list_display = ['title'，'approved'，'author'，'user'，'categories'，'description'，'pub_date' 'submitted_date'，'upload'，'vote']
admin.site.register（FileModel，FileModelAdmin）
我会的像在另一个应用程序中的另一个模型new_user_model中的整数，当在管理站点中批准文件时，将整数字段'文件'增加1。这样我可以跟踪每个用户已经批准了多少个文件。
class NewUserModel（models.Model）：
user = models.OneToOneField（User，on_delete = models.CASCADE）
＃user = models.ForeignKey（User）
files = models.IntegerField（default = 0）
文件模型
class FileModel（models.Model）：
title = models.CharField（max_length = 100）
description = models.CharField（max_length = 255）
pub_date = models.DateTimeField日期发布'）
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（）.....................
。 ......... .........................................
所以我希望在new_user_model中的文件字段在文件被批准时增加1，并在管理站点中点击保存按钮。另外，如果已批准被取消选中，我需要将文件字段减少一个。
如何才能完成？
更新：
最终我希望能够显示用户在该网站上的文件数。
谢谢，
我终于有机会完成这个从django.contrib导入admin

admin.site.register（FileModel，FileModelAdmin）
I am building a Django app for uploading files. I would like to be able to count the number of files a users has and which are approved. I have a model with a Boolean 'approved' field. This model is in admin.py.
In 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)
I would like an integer in another model 'new_user_model', which is in another app, to increase an integer field 'files' by one when a file is approved in the admin site. This way I could keep track of how many files have been approved for each user.
class NewUserModel(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
# user = models.ForeignKey(User)
files = models.IntegerField(default=0)
The model for the files,
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().....................
...................................................
So I want the files field in new_user_model to increase by one when a file is 'approved' and the save button hit in the admin site. Also if the 'approved' is unchecked I would need the 'files' field to reduce by one.
How could this be done?
Updated:
Ultimately I would like to be able to display the number of files a user has on the site.
Thanks,
I finally got a chance to complete this?
