我有一个名为Genre(三级层次结构)的树结构,它与用户有很多相关。用户选择流派叶节点。 以下是我的model.py
class Genre(MPTTModel):
name = models.CharField(max_length=50, unique=True)
parent = TreeForeignKey('self', null=True, blank=True, related_name='children')
def __unicode__(Self):
return Self.name
class MPTTMeta:
order_insertion_by = ['name']
class UserProfile(BaseModel):
.....
genre = models.ManyToManyField(Genre)
zipcode = models.PositiveIntegerField(default=0)
about = models.CharField(verbose_name=_('Description'), blank=True)
我分别为每个树叶节点创建了表单字段,因为我想在表单中自定义树渲染。它看起来像这样
class SignupFormStep2(forms.Form):
class Meta:
model = User
fields = ('date_of_birth', 'gender', 'zipcode',)
first_name = forms.CharField(label=_('First name'), max_length = 25, initial='', widget=forms.TextInput(attrs={'readonly':'readonly'}))
last_name = forms.CharField(label=_('Last name'), max_length = 25, initial='', widget=forms.TextInput(attrs={'readonly':'readonly'}))
email = forms.EmailField(label=_('Email'), max_length = 255, initial='', widget=forms.TextInput(attrs={'readonly':'readonly', 'disabled':True}))
about = forms.CharField(label=_('Description'), initial='')
cat=range(0,Genre.tree.filter(level=0).count())
for x in range(0, len(cat)):
cat[x]=Genre.tree.filter(level=0)[x]
subcat=[None]*len(cat)
for x in range(0, len(cat)):
subcat[x]=cat[x].get_children()
genre_0_0=forms.ModelMultipleChoiceField(queryset=cat[0].get_children()[0].get_children(),widget=forms.CheckboxSelectMultiple)
genre_1_0=forms.ModelMultipleChoiceField(queryset=cat[1].get_children()[0].get_children(),widget=forms.CheckboxSelectMultiple)
genre_1_1=forms.ModelMultipleChoiceField(queryset=cat[1].get_children()[1].get_children(),widget=forms.CheckboxSelectMultiple)
genre_1_2=forms.ModelMultipleChoiceField(queryset=cat[1].get_children()[2].get_children(),widget=forms.CheckboxSelectMultiple)
genre_1_3=forms.ModelMultipleChoiceField(queryset=cat[1].get_children()[3].get_children(),widget=forms.CheckboxSelectMultiple)
genre_2_0=forms.ModelMultipleChoiceField(queryset=cat[2].get_children()[0].get_children(),widget=forms.CheckboxSelectMultiple)
genre_2_1=forms.ModelMultipleChoiceField(queryset=cat[2].get_children()[1].get_children(),widget=forms.CheckboxSelectMultiple)
我也使用向导表单进行多次注册,但这不是问题。 我的观点看起来像这样
class SignupWizard(SessionWizardView):
def get_form_prefix(self, step=None, form=None):
return ''
def get_template_names(self):
return [SIGNUP_TEMPLATES[self.steps.current]]
def save_user(self, form_list, **kwargs):
print 'save_user'
form_data = [form.cleaned_data for form in form_list]
session_key = self.request.session.session_key
try:
image = UploadProfileImage.objects.get(key=session_key).image
except UploadProfileImage.DoesNotExist:
pass
user = User()
password = form_data[0]['password1']
if password:
user.set_password(password)
else:
user.set_unusable_password()
user.is_active = True
user.username = (form_data[0]['email']) #temp maybe add user field??
user.first_name = form_data[0]['first_name']
user.last_name = form_data[0]['last_name']
user.email = form_data[0]['email']
user.save()
profile = user.profile
profile.date_of_birth = form_data[1].get('date_of_birth')
profile.zipcode = form_data[1].get('zipcode', 0)
#profile.genre = form_data[2].save
profile.genre = Genre.
#availability
return user
我不知道如何将所有表单字段(为单个树叶节点生成)保存到视图中的单个用户模型属性类型中。
任何想法如何合并多个表单字段并保存到多个模型属性。
先谢谢。
