Question

在以下代码中，

form.is_valid始终设置为false。如何实现代码以检查其错误原因。

我已将代码提供给下面的forms.py，model.py和views.py。

表单定义表单视图处理表单模型定义了模型

forms.py

    class VolunteerForm(forms.ModelForm):
        volposition = forms.CharField(label="VolunteerPosition",widget=forms.Textarea(attrs={'cols':30,'rows':1}))
        roledesc = forms.CharField(label="Role Description",widget=forms.Textarea(attrs={'cols':30,'rows':5}))
        noofhours = forms.CharField(widget=forms.Select(choices=NO_OF_HRS_MONTH),max_length=2)
        Qualreqt  = forms.CharField(label="Qualifications and Requirements",widget=forms.Textarea(attrs={'cols':30,'rows':5}))
        Duration      = forms.CharField(widget=forms.Select(choices=NO_OF_HRS),max_length=2)
        Durationyrmon = forms.CharField(widget=forms.Select(choices=YR_MONTH),max_length=10)
        posstatus     = forms.CharField(widget=forms.Select(choices=POS_STATUS),max_length=1)
        teamrelation  = forms.CharField(max_length=50)
