我得到了这样的错误。我无法保存我的表格。请帮我保存我的表格

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>

我还希望在我的代码中添加 ajaxcode，以便在一个页面中显示前 3 个表单文件。剩下 2 个字段的下一页。并且页面想要在单个窗口中显示。并且还必须验证字段。但我对使用 django 的 ajax 没有明确的想法。我如何在我的代码中应用所有这些东西

Answer 1

您无法保存表单。表单用于向用户（通常）显示模型（DB）中的数据。您可以使用forms.ModelForm 保存模型的实例来自表单：

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

forms.py

class UserForm(forms.ModelForm):
    pass

    class Meta:
        model = UserDetails

附言Django 已经内置了身份验证，因此无需复制代码。看看django.contrib.authhttps://docs.djangoproject.com/en/dev/topics/auth/

Answer 2

您定义的 UserForm 不是 ModelForm，因此不是 does not have a save() method。

使用ModelForm 例如

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

Answer 3

我在 Django 3（2020 年 5 月）中遇到了 'UserForm' object has no attribute 'save' 错误。这是因为在我的表格中，我只给出了forms.Form。

我是这样改正的：

class my_form_name(forms.Form,forms.ModelForm)

注意：元类很重要。
