我的表单中有一个有效的保存方法,一旦我升级它就表现得很奇怪,我似乎无法调试问题的根源
我有一个从 ModelForm 继承的简单表单,在其中我覆盖了 save 方法以保存一些外部属性
下面是我的代码
class UserProfileForm(ExtendedMetaModelForm):
"""
UserProfileForm
"""
_genders = (
('M', _('Male')),
('F', _('Female')),
)
birthday = forms.DateField(
widget=extras.SelectDateWidget(attrs={'class' : 'span1'},years=(range(1930, datetime.now().year-14))),
label = _('Birthday'),
required= False,
error_messages = {
'required' : _('Birthday is required.')
}
)
gender = forms.CharField(
label = _('Gender'),
widget = forms.Select(choices=_genders)
)
bio = forms.CharField(required=False, widget=forms.Textarea(attrs={'rows' : '4'}))
class Meta:
model = User
fields = ('first_name', 'last_name', 'bio', 'birthday', 'gender', 'email',)
def __init__(self, *args, **kwargs):
super(UserProfileForm, self).__init__(*args, **kwargs)
if self.instance:
self.fields['email'].widget.attrs['readonly'] = True
self.fields['birthday'].initial = self.instance.get_profile().birthday
self.fields['bio'].initial = self.instance.get_profile().bio
for i in self.fields:
if isinstance(self.fields[i], forms.CharField):
self.fields[i].widget.attrs["class"] = 'input-xlarge'
def save(self, *args, **kw):
super(UserProfileForm, self).save(*args, **kw)
self.instance.get_profile().bio = self.cleaned_data.get('bio')
self.instance.get_profile().birthday = self.cleaned_data.get('birthday')
self.instance.get_profile().save()
以上工作正常,现在。在初始化表单时,它会从配置文件中检索 bio、birthday 的初始值。
但是,在保存时它会继续前进而没有任何动作。我的个人资料模型非常基本,保存方法没有改变它使用models.Model的原始操作
任何人都可以就为什么会发生这种情况提出建议吗?
PS没有返回错误,它只是没有保存任何东西
更新(添加了 ExtendedMetaModelForm 类):
class ExtendedMetaModelForm(forms.ModelForm):
"""
Allow the setting of any field attributes via the Meta class.
"""
def __init__(self, *args, **kwargs):
"""
Iterate over fields, set attributes from Meta.field_args.
"""
super(ExtendedMetaModelForm, self).__init__(*args, **kwargs)
if hasattr(self.Meta, "field_args"):
# Look at the field_args Meta class attribute to get
# any (additional) attributes we should set for a field.
field_args = self.Meta.field_args
# Iterate over all fields...
for fname, field in self.fields.items():
# Check if we have something for that field in field_args
fargs = field_args.get(fname)
if fargs:
# Iterate over all attributes for a field that we
# have specified in field_args
for attr_name, attr_val in fargs.items():
if attr_name.startswith("+"):
merge_attempt = True
attr_name = attr_name[1:]
else:
merge_attempt = False
orig_attr_val = getattr(field, attr_name, None)
if orig_attr_val and merge_attempt and\
type(orig_attr_val) == dict and\
type(attr_val) == dict:
# Merge dictionaries together
orig_attr_val.update(attr_val)
else:
# Replace existing attribute
setattr(field, attr_name, attr_val)
