我的Django中间件无法正常工作 [英] My Django Middleware Isn't Working The Way It Should

问题描述

如何将中间件文件中的reason从UserBanning模型传递到banned.html?几乎所有东西都可以正常工作，但是我似乎无法从模型中获取reason并以模板banned.html的形式显示，而且不确定方式，因此只要深入学习中间件，任何帮助都将是惊人的.我应该改用process_request()吗?

How do I go about passing the reason to banned.html from the UserBanning model from the middleware file? Almost everything works but I can't seem to get the reason from the model to display in the template banned.html and im unsure way so any help will be amazing just got into learning about middleware. Should I be using process_request() instead?

谢谢

models.py:

models.py:

from django.db import models
from django.contrib.auth.models import User
from django.conf import settings

class UserBanning(models.Model):
    user = models.ForeignKey(User, verbose_name="Username", help_text="Choose Username", on_delete=models.CASCADE)
    ban = models.BooleanField(default=True, verbose_name="Ban", help_text="Users Bans")
    reason = models.CharField(max_length=500, blank=True)

    class Meta:
        verbose_name_plural = "User Banning"
        ordering = ('user',)

    def __str__(self):
        return f"{self.user}"

middleware.py:

middleware.py:

from .models import UserBanning
from django.shortcuts import render


class BanManagement():
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        banned = UserBanning.objects.all()
        context = {
            'banned': banned,
        }

        if(banned.filter(ban=True, user_id=request.user.id)):
            return render(request, "account/banned.html", context)
        else:
        response = self.get_response(request)
        return response

banned.html:

banned.html:

{% extends "base.html" %}

{% block content %}
<p>Your account has been banned. Reason: {{ banned.reason }}</p>
{% endblock content %}

推荐答案

您快完成了.剩下的问题是，在设置context之前，您需要在request.user.id上的filter，以便上下文仅包含此特定用户的禁令.像这样:

You're almost done. The remaining problem is that you need to filter on request.user.id before you set the context, in order for the context to contain this specific user's ban only. Something like:

    banned = UserBanning.objects.filter(ban=True, user=request.user)

    if banned:
        context = {'banned': banned[0]}
        return render(request, "account/banned.html", context)
    else:
