Question

我在第一个django项目中工作。不幸的是，我面临的问题应该是直截了当的。我的情景：

models.py

from django.db import models

# Create your models here.

## 1. Model for user registration

class subjects(models.Model):
    description = models.CharField(max_length=500)

    def __Str__(self):
        return self.description

views.py

from django.contrib.auth import login , authenticate
from django.shortcuts import render , redirect 
from poc_teaching.models import subjects

# Create your views here.


def list_subj(request): 
    subj = subjects.objects.all()

    return render (request,'subjects.html',{'subjects': subj})

urls.py

from django.conf.urls import url
#from . import views
from poc_teaching import views as poc_views


urlpatterns = [

    url('subjects/$',poc_views.subjects,name ='subjects'),

]

HTML

<head>
"hello world"
</head>
<div>
{{ subjects }}
</div>

我收到错误：'subjects' object has no attribute 'get'

我已通过管理控制台添加对象。所以，我很确定我应该得到结果。我通过很多文件，但我真的不明白我的问题在哪里。感谢您的帮助。

Answer 1

您正在调用错误的视图。您的urlpattern应该调用视图list_subj。

将您的urlpatterns更改为此 -

urlpatterns = [
    url('^subjects/$',poc_views.list_subj,name ='subjects'),
]

django错误：＆＃39;科目＆＃39;对象没有属性＆＃39; get＆＃39;
