用Django查询不起作用

Question

I am new to Django and Python. This is my first post here!:

I have been trying to "print" on some website I made with Django some objects from a database that I made with HeidySQL.

The app inside Django is called users. So 127.0.0.1: 8000/users, inside this I have another page in 127.0.0.1:8000/users/login that is loading fine.

I successfully synced this DB with Django, I even managed to see some rows in the Django shell, which is why I concluded everything seems to be connected well.

This login.html file atm has this:

{% block content %}
<h1>{{ allcharacters_query }} </h1>

</body>

{% endblock %} 

The issue is that it doesn't display the names of my characters_list.

Here is my views.py:

from django.http import HttpResponse
from django.shortcuts import render
from users.models import Characters
from django.template.response import TemplateResponse

def index (request):
    return render(request,'users/home.html')

def return_charnames (request):
    allcharacters_query = Characters.objects.all()
    return render(request, 'users/login.html',{"allcharacters_query": 
    allcharacters_query})

And this my urls.py file:

from django.conf.urls import url, include, patterns
from .import views
from django.contrib.auth.views import login

urlpatterns = [
    url(r'^$', views.index,name='index'),
    url(r'^login/$',login,{'template_name': 'users/login.html' })

]

I don't really know how to fix this. I have read lots of documentation from the official Django site and watched lots of videos, however, I am stuck here. Thanks all!

Answer 1

如果要覆盖登录方法，则必须使用view render而不是django的视图进行登录。

 url(r'^login/$',views.return_charnames) 

Answer 2

Replace

{% for lista in characters_list %}

by:

{% for lista in allcharacters_query %}

characters_list doesn't exist in your template.

And there is no URL calling your view return_charnames in your url file.

Answer 3

您应该将return_charnames添加到urls.py中，以正确的url显示html内容。
