AttributeError - 模块 'django.http.request' 没有属性 'META'

Question

我得到了这个错误，但我做了完全相同的事情：

属性错误在 /courses/ 模块 'django.http.request' 没有属性 'META'

错误发生在：

from django.shortcuts import render
from django.http import request
from django.http import HttpResponse
from .models import Course

# Create your views here.
def course_list(response):
    courses = Course.objects.all()
    return render(request, 'courses/course_list.html',{'courses':courses})

#    output=', '.join([str(course) for course in courses])
#    return HttpResponse(output)

但是服务器显示没有任何问题。

Answer 1

您的函数参数称为response，但随后您使用request 这是您导入的模块，将字段参数更改为request 或将其在函数内的用法更改为response

def course_list(request):
    courses = Course.objects.all()
    return render(request, 'courses/course_list.html',{'courses':courses})

def course_list(response):
    courses = Course.objects.all()
    return render(response, 'courses/course_list.html',{'courses':courses})
