django中非常简单的用户输入

Question

我的潜在困难是我无法理解django模板,视图和网址是如何绑在一起的...提示用户输入字符串的最简单,最简单的方法是什么,然后使用该字符串查询数据库(最好w/python模型不是原始的SQL查询)？我应该使用GET和POST方法吗？我应该使用表格吗？我需要使用模板还是可以使用通用视图？

当我尝试提交输入时,它只是重新加载输入页面.

views.py:

from django.shortcuts import render
from django.shortcuts import HttpResponse
from People.models import Person

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

def search(request):
    search_id = request.POST.get('textfield', None)
    try:
        user = Person.objects.get(MAIN_AUTHOR = search_id)
        #do something with user
        html = ("<H1>%s</H1>", user)
        return HttpResponse(html)
    except Person.DoesNotExist:
        return HttpResponse("no such user")  

urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^People/', 'People.views.index'), 
    url(r'^People/send/', 'People.views.search'),
)

模板:

<form method="POST" action="send/">
{% csrf_token %}
<input type="text" name="textfield">

<button type="submit">Upload text</button>
</form>

我错过了什么或做错了什么？

如果我理解正确,您希望从用户那里获取一些输入,查询数据库并根据输入显示用户结果.为此,您可以创建一个简单的django表单来获取输入.然后,您可以将参数传递给GET请求中的视图,并在数据库中查询关键字.

编辑:我编辑了代码.它现在应该工作.

views.py

from django.shortcuts import render
from django.shortcuts import HttpResponse
from .models import Person
from django.core.exceptions import *

def index(request):
    return render(request, 'form.html')

def search(request):
    if request.method == 'POST':
        search_id = request.POST.get('textfield', None)
        try:
            user = Person.objects.get(name = search_id)
            #do something with user
            html = ("<H1>%s</H1>", user)
            return HttpResponse(html)
        except Person.DoesNotExist:
            return HttpResponse("no such user")  
    else:
        return render(request, 'form.html')

urls.py

from django.conf.urls import patterns, include, url
from People.views import *

urlpatterns = patterns('',
    url(r'^search/', search),
    url(r'^index/', index)
)

form.html

<form method="POST" action="/search">
{% csrf_token %}
<input type="text" name="textfield">

<button type="submit">Upload text</button>
</form>

另外,请确保将模板放在一个名为的单独文件夹中templates,并将其添加到settings.py:

TEMPLATE_DIRS = (
    os.path.join(os.path.dirname(__file__), '../templates').replace('\\','/'),
)
