我得到了这样的错误。我无法保存我的表格。请帮我救我的形式

我的代码如下

#view 

from django.shortcuts import render_to_response 
from registration.models import UserDetails 
from forms import UserForm 
from django import forms 
from django.template import RequestContext 
from django.http import HttpResponseRedirect 

def user_details(request): 
    if request.method == 'POST': 
     form = UserForm(request.POST) 
     if form.is_valid(): 
      form.save() 
      return HttpResponseRedirect('/thanx/') 

    else: 
     form = UserForm()   
    return render_to_response("career.html", {"form": form},context_instance=RequestContext(request)) 


#form 

    from django import forms 
from registration.models import UserDetails 


class UserForm(forms.Form): 
    fname=forms.CharField(max_length=20) 
    lname=forms.CharField(max_length=20) 
    email = forms.EmailField() 
    address = forms.CharField(max_length=50) 
    country = forms.CharField(max_length=20) 

#model 

from django.db import models 

class UserDetails(models.Model): 
    fname=models.CharField(max_length=20) 
    lname=models.CharField(max_length=20) 
    email = models.EmailField() 
    address = models.CharField(max_length=50) 
    country = models.CharField(max_length=20) 
    def __unicode__(self): 
     return self.fname 
     return self.lname 
     return self.email 
     return self.address 
     return self.country 


#url 

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

from django.contrib import admin 
admin.autodiscover() 
# Uncomment the next two lines to enable the admin: 
# from django.contrib import admin 
# admin.autodiscover() 

urlpatterns = patterns('', 
    # Examples: 
    url(r'^registration/$', 'registration.views.user_details', name='user_details'), 
    # url(r'^mysite7/', include('mysite7.foo.urls')), 

    # Uncomment the admin/doc line below to enable admin documentation: 
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')), 

    # Uncomment the next line to enable the admin: 
     url(r'^admin/', include(admin.site.urls)), 
) 

# template 

<form enctype="multipart/form-data" method="post">{% csrf_token %} 
    {{ form.as_p }} 
    <input type="submit" ....> 
</form> 

我也希望我的代码添加ajaxcode的形式在一个页面DISPLY第3周的Fileds。剩余2个字段的下一页。并且页面想要在单个窗口中显示。还必须验证这些字段。但我没有关于django的ajax的清晰想法。我如何在我的代码中应用所有这些东西

Answer 1

您定义的用户窗体不是ModelForm，因此也不是does not have a save() method。

使用ModelForm例如

class UserForm(forms.ModelForm): 
    class Meta: 
     model = UserDetails 

Answer 2

您无法保存表格。表单用于将数据从模型（DB）显示给用户（通常）。您可以使用forms.ModelForm形式从保存模型的一个实例：

https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#the-save-method

forms.py

class UserForm(forms.ModelForm): 
    pass 

    class Meta: 
     model = UserDetails 

附： Django已经内置了身份验证，因此不需要复制代码。看看django.contrib.authhttps://docs.djangoproject.com/en/dev/topics/auth/
