Question

我是Django的新手。我只是学习使用表单和模型。在这里，我使用了modelforms来获取两个字段（用户名和密码）并保存它。我想要做的是获取该用户名的模型ID。下面是代码。但我无法得到身份证。

from django.http import HttpResponse, Http404, HttpResponseRedirect
from django.core.urlresolvers import reverse
from reg.models import registration, registrationform
from django.shortcuts import render_to_response, get_object_or_404
from django.template import RequestContext


def registration(request):
        if request.method == 'POST':
            form = registrationform(request.POST)
            if form.is_valid():
                form.save()
            username = form.cleaned_data['username']
            p = registration.objects.all()
            for loop in p:
                if loop.username == username:
                    id = loop.id
            return HttpResponseRedirect(reverse('reg.views.thanks', args=(id)))
    else:
        form = registrationform()
    return render_to_response('registration.html', {'form' : form}, context_instance=RequestContext(request))

def thanks(request, id):
        p = get_object_or_404(registration, pk=id)  
    return render_to_response('thanks.html', {'reg': p)

还有一个问题。密码的型号字段是什么？

感谢。

Answer 1

 if request.method == 'POST':
            form = registrationform(request.POST)
            if form.is_valid():
                data =form.save()
                #...
                id = data.id
                #...
            return HttpResponseRedirect(reverse('reg.views.thanks', args=(id)))

Answer 2

user = form.save(commit=False)
user.first_name = u'First name'
user.last_name = u'Last name'
user.save()

密码使用密码1字段

如何将注册功能更改为：

def registration(request):
    if request.method == 'POST':
        form = registrationform(request.POST)
        if form.is_valid():
            userdetails = form.save()
            user = userdetails.username
            val = registration.objects.get(username = user)
            return HttpResponseRedirect(reverse('reg.views.thanks', args=(val.id)))
    else:
        form = registrationform()
        return render_to_response('registration.html', {'form' : form}, context_instance=RequestContext(request))

我建议你阅读：https://docs.djangoproject.com/en/dev/topics/forms/modelforms/

请问你可以粘贴urls.py吗？

我最近遇到的问题几乎与此完全相同 - 这只是一个错字，我在url函数的第二个字段中输入了错误的值：

url(r'^people/thanks/(?P<person_id>\d+)$', 'people.views.thanks'),

应该是：

url(r'^people/thanks/(?P<person_id>\d+)$', 'people.views.new'),

如何获取特定模型的id？
