AttributeError - 模块“django.http.request”没有属性“META”

Question

我收到此错误，但我做了完全相同的事情：

/courses/模块'django.http.request'处的AttributeError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)

但服务器根本没有显示任何问题。

Answer 1

您的函数参数被调用response，但随后您使用request导入的模块，更改要调用的字段参数request或更改其在函数内的用法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})
