我正在开发一个包含多个模型的应用程序。在我的 model.py 中的第二个模型中，它由 2-3 列组成。char 字段，但在我的模板中，当我使用此{{ form.billing_add }}时，它不会在浏览器中显示任何文本输入

我的 model.py 文件是

从 django.db 导入模型 从 django.contrib.auth.models 导入用户

class Customer(models.Model):
    user        =models.OneToOneField(User)
    birthday    =models.DateField()
    website     =models.CharField(max_length=50)
    store       =models.CharField(max_length=50)
    welcomemail =models.CharField(max_length=50)

    def __unicode__(self):
             return self.user

class Customer_check_attributes(models.Model):
    customer    = models.ForeignKey(Customer)
    billing_add =models.CharField(max_length=50)
    shipping_add    =models.CharField(max_length=50)
    payment_method  =models.CharField(max_length=50)
    shipping_method =models.CharField(max_length=50)
    reward_points   =models.CharField(max_length=50)

我的 form.py 文件为

from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
from customer_reg.models import Customer,Customer_check_attributes

class Registration_Form(ModelForm):
       first_name  = forms.CharField(label=(u'First Name'))
       last_name   = forms.CharField(label=(u'Last Name'))      
       username   = forms.CharField(label=(u'User Name'))
       email      = forms.EmailField(label=(u'Email Address'))
       password   = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))

       class Meta:
              model=Customer

              exclude=('user',)

您似乎想要一个具有多个模型属性的 html 表单。因此，方法是为每个模型创建单独的表单，但通过一个视图和模板将其显示在一个页面上，并以相同的方式处理它。

这是示例

形式

#additional user attributes 
class Registration_Form(ModelForm):
     first_name  = forms.CharField(label=(u'First Name'))
     last_name   = forms.CharField(label=(u'Last Name'))      
     username   = forms.CharField(label=(u'User Name'))
     email      = forms.EmailField(label=(u'Email Address'))
     password   = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))
     class Meta:
         model = User

class CustomerForm(ModelForm):
     class Meta:
         model = Customer
         exclude=('user',)

class Customer_check_attributesForm(ModelForm):
     class Meta:
         model = Customer_check_attributes
         exclude=('user',)

看法：

def customer_add(request):
    if request.method == 'POST':
         uform = Registration_Form(request.POST)
         cform = CustomerForm(request.POST)
         caform = Customer_check_attributesForm(request.POST)
         if uform.is_valid() :
             ...
             user = uform.save()
         if cform.is_valid() :
             ...
             customer = cform.save()
         if caform.is_valid() :
             ...
             cattr = caform.save()
  else:
      uform = Registration_Form()
      cform = CustomerForm()
      caform = Customer_check_attributesForm()         
  ctx = { 'uform': uform, 'cform':cform, 'caform': caform }
    return render_to_response('add_customer_template.html', ctx,
                context_instance = RequestContext(request))

示例 add_customer_template.html

 <form> 
     {#other rendering logic#}
     {{ uform.as_p }}
     {{ cform.as_p }}
     {{ caform.as_p }}
 </form>

注意：这是一个指导代码。处理错误和更好的逻辑还有改进的余地。
