如果我尝试通过CBV CreateView输入数据，则获取IntegrityError，但管理面板上的所有内容都可以正常工作。
型号：
class Account(Info):
firm = models.ForeignKey(
Firm
)
name = models.CharField(
max_length=100
)
is_default = models.BooleanField(
default=False
)
type = models.CharField(
max_length=1, choices=ACCOUNT_TYPE_CHOICES
)
category = models.CharField(
max_length=1, choices=ACCOUNT_CATEGORIES
)
sub_category = models.CharField(
max_length=1, choices=ACCOUNT_SUB_CATEGORIES
)
show_in = models.CharField(
max_length=1, choices=SHOW_IN
)
class Meta:
ordering = [
'name'
]
unique_together = (
'firm', 'name'
)
查看：
class CreateAccountView(LoginRequiredMixin, CreateView):
success_url = '/'
form_class = CreateAccountForm
http_method_names = ['get', 'post']
template_name = 'create_templates/create_account.html'
def get_context_data(self, **kwargs):
context = super(CreateAccountView, self).get_context_data(**kwargs)
firm_obj = self.get_firm_obj(self.kwargs.get('f_id'))
context['firm_obj'] = firm_obj
return context
def form_valid(self, form):
form.instance.firm = self.get_firm_obj(self.kwargs.get('f_id'))
form.instance.is_default = False
form.instance.sub_category = '4'
super(CreateAccountView, self).form_valid(form)
return HttpResponse(
'''
<script>
window.close();
window.onunload = refreshParent; function refreshParent() {
window.opener.location.reload();
}
</script>
'''
)
@staticmethod
def get_firm_obj(f_id):
return get_object_or_404(Firm, id=f_id)
形式：
class CreateAccountForm(forms.ModelForm):
name = forms.CharField(
label='Account Name', max_length=100,
widget=forms.TextInput(
attrs={
'class': 'form-control'
}
)
)
class Meta:
model = Account
fields = (
'name', 'type',
'category', 'show_in'
)
widgets = {
'type': forms.Select(
attrs={
'class': 'form-control'
}
),
'category': forms.Select(
attrs={
'class': 'form-control'
}
),
'show_in': forms.Select(
attrs={
'class': 'form-control'
}
)
}

Exception Type: IntegrityError at /add_account/f/1/
Exception Value: columns firm_id, name are not unique
使用sqlite进行开发。如果我尝试通过管理面板输入重复条目，那么一切工作正常通过管理面板我得到Account with this Firm and Name already exists.这是正确的，但为什么我没有通过CBV看到此错误
答案 0 :(得分：1)
您已从表单中排除firm，并且在验证之前不会将其添加，因此表单无法验证公司和名称的组合是否为独特。您需要以其他方式在表单中传递它，并在表单clean方法中明确检查该组合中没有现有实例。
答案 1 :(得分：0)
此定义表示＆＃34;此公司和名称的帐户已存在。＆＃34;在这两种情况下，您都收到相同的错误，
unique_together = (
'firm', 'name'
)
异常值：列firm_id，名称不唯一，这意味着与管理面板错误相同。
