私はDjangoの初心者です。なぜこれがうまくいかないのか分かりません。djangoのフォームフィールドを変更する
私はどこform_class未解決の参照を取得していますOPTGROUPとviews.py forms.pyclass SystemForm(ModelForm):
"""Form to create and modify systems"""
# only show top-level UserTypes for application_user_type field
application_user_type = ModelChoiceField(
queryset=UserType.objects.filter(parent__isnull=True), required=False,
help_text="Type of user who interacts with the system")
lines_of_business = ModelMultipleChoiceField(
widget=forms.widgets.CheckboxSelectMultiple(), queryset=LineOfBusiness.objects.all(),
required=False, help_text="Identify lines of business this system touches"
)
customer_segments_served = ModelMultipleChoiceField(
widget=forms.widgets.CheckboxSelectMultiple(), queryset=CustomerSegment.objects.all(),
required=False, help_text="Customer segments this resource serves"
)
application_user_sub_type = ModelMultipleChoiceField(
widget=forms.widgets.CheckboxSelectMultiple(), queryset=UserType.objects.filter(parent__name='Internal'),
required=False, label="Internal user type"
)
primary_purpose_business_use = ModelChoiceField(
queryset=BusinessSystemType.objects.filter(parent__isnull=True), required=False,
help_text="primary business purpose")
class Meta:
model = System
fields = ['name', 'short_name', 'accountable_team', 'description', 'lines_of_business',
'business_system_type', 'customer_segments_served',
'application_user_type', 'other_application_user_type', 'application_user_sub_type',
'intellectual_property', 'deployment_model',
'business_criticality', 'service_criticality',
'vendor', 'other_vendor', 'technology_type', 'other_technology_type',
'associated_technologies', 'renewal_date',
'installation_date', 'deprecation_date', 'purchase_price',
'contract_signed_date', 'contract_end_date', 'parimary_purpose_business_use', 'documentation_url', 'notes', 'tags']
で
class SystemDetailView(DetailView):
"""Detail view for Systems"""
form_class = system_form()
model = System
template_name = 'systems/system_detail.html'
def get_context_data(self, **kwargs):
context = super(SystemDetailView, self).get_context_data(**kwargs)
context.update({
'system_update_form': self.form_class(instance=self.get_object()),
})
return context
def system_form(self):
form= SystemForm
form.fields['primary_purpose_business_use'].choices= list()
for optgroup in BusinessSystemType.objects.all():
form.fields['primary_purpose_business_use'].choices= form.fields['primary_purpose_business_use'].choices.append(
optgroup.name, list(subtype.name for subtype in BusinessSystemType.objects.filter(parent= optgroup))
)
return SystemForm
でそのオプション
でフィールドを初期化しようとしている
= system_form() 私は何が間違っていますか?おそらくたくさん。しかし、私を助けてくれますか?
views.py' 'であなたは' SystemForm'をインポートしたのですか? –
はい、私はしました。しかし、私は明らかにここで何か間違っている.... – PowerLove
