问题描述
< select name =menu>

< option value =1> imp 1< / option>
< option value =2> imp 2< / option>
< option value =3> imp 3< / option>

我有文件上传工作与这个课程
$ b title = forms.CharField(max_length = 50)
file = forms.FileField(widget = forms.FileInput( ))
应该怎么样,该类的外观与添加的选择?
或者如何使用文件上传表单并从select中获取值,并根据该值执行操作?
解决方案
您需要使用 ChoiceField :
IMP_CHOICES =(
('1','imp 1'),
('2' ,'imp 2'),
('3','imp 3'),
('4','imp 4'),
)
class UploadFileForm(forms.Form):
title = forms.CharField(max_length = 50)
file = forms.FileField(widget = forms.FileInput())
imp = forms.ChoiceField choices = IMP_CHOICES)
I'm making an app that has a file name field, an upload file field and a select. Lets say I have something like this for the select
<select name="menu">
<option value="0" selected> select imp </option>
<option value="1"> imp 1 </option>
<option value="2"> imp 2 </option>
<option value="3"> imp 3 </option>
<option value="4"> imp 4 </option>
</select>
<input type="submit" value="Upload" />
I have the file upload working with this class
class UploadFileForm(forms.Form):
title = forms.CharField(max_length=50)
file = forms.FileField(widget=forms.FileInput())
How should the class look with the select added to it? Or how can I use the file upload form and get the value from the select, and based on that value do an action?
解决方案
You need to use a ChoiceField:
IMP_CHOICES = (
('1', 'imp 1'),
('2', 'imp 2'),
('3', 'imp 3'),
('4', 'imp 4'),
)
class UploadFileForm(forms.Form):
title = forms.CharField(max_length=50)
file = forms.FileField(widget=forms.FileInput())
imp = forms.ChoiceField(choices=IMP_CHOICES)
