my models i think this is the only part that i know what is goin on我的模型我认为这是我知道发生了什么的唯一部分
from tkinter import CASCADE, Widget
from django.db import models
from django.contrib.auth.models import User
class Post (models.Model):
id = models.AutoField(primary_key=True)
name = models.ForeignKey(User, on_delete=models.CASCADE, default='User')
text = models.TextField (max_length=200)
posted = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.text
class Comment(models.Model):#comment for the requests
request = models.ForeignKey('sunu_app.Post', on_delete =models.CASCADE , related_name='comments', null=True , blank=True)
# name = models.ForeignKey(User, on_delete=models.CASCADE , null=True , blank=True)
text = models.TextField ()
posted = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.text
my views i honestly had no idea what was going on there我的观点老实说,我不知道那里发生了什么
# from typing_extensions import Self
from urllib.request import Request
from django.http import HttpResponse
from django.shortcuts import get_object_or_404, render
from django.shortcuts import render,redirect
from .forms import *
from .models import *
def home(request):
requests = Post.objects.all().order_by('-posted')
count = Post.objects.all().count()
#diplay the comments here and let it save in commentform.view
comments = Post.comment_set.all()
context = {'requests':requests , 'count':count , 'comments':comments}
return render(request,'sunu_app/home.html', context)
# context = {'cases':rooms} the second value is the data
# you want to pass the first value is what it should be called in the template
def requestform (request):
form = RequestForm(request.POST)
if form.is_valid():
form.save()
return redirect('home')
context = {'requestform':form}
return render(request,'sunu_app/RequestForm.html',context)
def deleteall(request):
requests = Post.objects.all()
requests.delete()
return render(request,'sunu_app/home.html')
def commentform(request ,post_id):
form = CommentForm(request.POST)
requests = Post.objects.get(id = post_id)
#save the comments here and let it display in home.view
if request.method == 'POST':
comment = Comment.objects.create{
request = requests,
}
#pls i have no single idea what is goin on here
context = {"commentform":form}
return render(request,'sunu_app/CommentForm.html',context)

pls if you can also give me any other tips i would highly appreciate it.如果您还可以给我任何其他提示,我将不胜感激。 thanks谢谢
Here you have set relation between them:在这里,您已经设置了它们之间的关系:
class Comment(models.Model):
request = models.ForeignKey('sunu_app.Post', ...)
...
So while you create new Comment
object, you need to pass Post
id or whole object to field request
(I strongly recommend naming it post
instead of request
):因此,当您创建新的Comment
对象时,您需要将Post
id 或整个对象传递给字段request
(我强烈建议将其命名为post
而不是request
):
post = Post.objects.get(id=1)
comment = Comment.objects.create( # use round parenthesis
request = post,
)
