表单数据没有存储在数据库中.有什么问题吗?

Question

这个表单工作正常，

class FeedBackForm(forms.Form):
feedBACK = forms.CharField(widget=forms.Textarea, required=True)  

但是这个表单不起作用

class FeedBackForm(forms.Form):
feedBACK = forms.CharField(widget=forms.Textarea, required=True)     
rating = forms.CharField(widget=forms.IntegerField, required=True)

显示如下错误问题发生在哪里?我检查了文档，但没有找到任何线索。

Answer 1

AnIntegerField^[Django-doc]是一个表单字段，而不是一个部件。指定该字段为:

class FeedBackForm(forms.Form):
feedBACK = forms.CharField(widget=forms.Textarea)     
rating = forms.IntegerField()

---

注意:默认情况下，一个表单字段有required=True^[Django-doc]，因此你不需要标记字段。
