int（）参数必须是字符串或数字，而不是＆＃39;类别＆＃39;

Question

尝试加载我的类别时，我收到以下错误消息。发布的值为“1”并存在于DB中，

TypeError at /events/add/

int() argument must be a string or a number, not 'Category'

Exception Type:     TypeError
Exception Value:    

int() argument must be a string or a number, not 'Category'

views.py

 category = Category.objects.get(pk=form.cleaned_data['category'])

Answer 1

听起来像form.cleaned_data['category']返回的对象是类别对象，而不是数字。

如果是这种情况，请执行category = form.cleaned_data['category']

打印出来以确定。
