当我试图创建一封新的求职信时,我遇到了这个错误
Django=3.0
Python=3.7
<tr>
<td colspan="4">

以下是我的观点。py公司
class CoverLetterListView(View):
def get(self, request):
client = request.user.client
cover_letters = CoverLetter.objects.filter(client=client, deleted=False,
is_master=True)
return render(request, 'quotes/covers/cover_letters_list.django.html',
{'cover_letters': cover_letters})
def post(self, request):
client = request.user.client
name_form = forms.CoverLetterNameForm(request.POST)
cover_letters = CoverLetter.objects.filter(client=client, deleted=False)
if name_form.is_valid():
name_form.save_new(client=client)
else:
logger.warning(request, 'Invalid form')
return render(request, 'quotes/covers/cover_letters_list.django.html',
{'name_form': name_form, 'cover_letters': cover_letters})
这是我的表格。py公司
class CoverLetterNameForm(forms.ModelForm):
class Meta:
model = CoverLetter
fields = ('name',)
def save_new(self, client, master=True):
instance = self.save(commit=False)
instance.is_master = master
instance.client = client
return instance.save()
class CoverLetter(models.Model):
name = models.CharField(max_length=120)
title = models.CharField(max_length=120, blank=True, null=True)
is_master = models.BooleanField(default=False)
show_logo = models.BooleanField(default=False)
show_company_name = models.BooleanField(default=False)
logo = models.ImageField(upload_to=get_logo_path, blank=True, null=True)
text = BleachField(blank=True, null=True)
deleted = models.BooleanField(default=False)
client = models.ForeignKey(Client,on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add=True)
modified_at = models.DateTimeField(auto_now=True)
def __str__(self):
return self.name
