Question

如何正确使用 Django Forms

Answer 1

首先你要创建自己的Form类，继承于django的Form，
然后创建form中的字段，例子如下：

from django import forms
class AuthenticationForm(forms.Form):
"""
Base class for authenticating users. Extend this to get a form that accepts
username/password logins.
"""
username = forms.CharField(label=_("Username"), max_length=254)
password = forms.CharField(label=_("Password"), widget=forms.PasswordInput)

error_messages = {
'invalid_login': _("Please enter a correct username and password. "
"Note that both fields may be case-sensitive."),
'no_cookies': _("Your Web browser doesn't appear to have cookies "
"enabled. Cookies are required for logging in."),
'inactive': _("This account is inactive."),
}

Answer 2

1.定义form
class CustomerForm(ModelForm):
class Meta:
model = Customer
exclude = ('User','adder','addtime', 'adderip','status')

2.使用form
form = CustomerForm(request.POST)
if form.is_valid():
form.save()
3.显示
<article>
<span>{{ f.label_tag }} ：</span>
{{ f }}
<span class="help">{{ f.help_text }}</span>
<span class="error">{{ f.errors.as_text }}</span>
</article>
