我有一个包含 11 个字段和一个图像上传字段的表单。填写并点击提交后,我收到一个 TypeError 说需要一个整数。如果我删除图像字段,则不会出现此错误。检查图像目录,在引发错误之前将文件保存到服务器。
表格.py:
class ListingForm(ModelForm):
seller_email = forms.EmailField(max_length="", required=True, widget=forms.TextInput(attrs={'placeholder': "jsmith@stevens.edu"}))
title = forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"The Cat in the Hat"}))
edition = forms.IntegerField(required=True, widget=forms.TextInput(attrs={'placeholder':"5"}))
author = forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"Dr. Seuss"}))
isbn = forms.CharField(label="ISBN", required=True, widget=forms.TextInput(attrs={'placeholder':"9780717260591"}))
price = forms.FloatField(required=True, widget=forms.TextInput(attrs={'type':"number", 'placeholder':"50.00"}))
classcode= forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"MA115"}))
#description = forms.CharField(widget=forms.TextArea(attrs={'placeholder':"You should buy this because..."}))
condition = forms.ChoiceField(required=True, widget=forms.Select(), choices=([(4,"New"), (3,"Good"), (2,"Fair"), (1,"Poor")]))
seller_name = forms.CharField(required=True, widget=forms.TextInput(attrs={'placeholder':"John Doe"}))
seller_phone = forms.CharField(widget=forms.TextInput(attrs={'placeholder':"(555) 555-1234"}))
picture = forms.ImageField(widget=forms.FileInput('accept':"image/*"))
#picture = forms.ImageField()
uuid = forms.CharField(widget=forms.HiddenInput(), initial=uuid.uuid4())
timeposted = forms.CharField(widget=forms.HiddenInput(), initial=datetime.now())
sale_status = forms.BooleanField(widget=forms.HiddenInput(), initial=True)
class Meta:
model = Listing
fields = ('seller_email', 'title', 'edition', 'author', 'isbn', 'price', 'classcode', 'description', 'condition', 'seller_name', 'seller_phone', 'picture', 'uuid', 'timeposted', 'sale_status')
#exclude = ("uuid", "timeposted", "sale_status", "picture", "school")
