我对 Django 有点陌生。我试图在上传时选择文件后将文件发送到另一台服务器，但是 form.is_valid() 总是返回 false 不会让我输入 if
views.py-
def sent(request):
if request.method == 'POST':
form = SendFileForm(request.POST, request.FILES)
print "form is made"
print form.errors
if form.is_valid():
print "form is valid"
new_song = Song(songfile= request.FILES['songfile'])
new_song.save()
print "new song is made and saved"
l = List()
#cd = form.cleaned_data
#SENDS THE FILE TO SERVER GIVEN PATH
l.all_files(new_song.songfile.path)
return HttpResponseRedirect(reverse('get_files.views.sent'))
else:
print "form is not valid"
else:
form = SendFileForm()
songs = Song.objects.all()
return render_to_response('sent.html', {'songs': songs,'form': form}, context_instance=RequestContext(request))
sent.html模板-
{% if form.errors %}
<p style="color: red;">
Please correct the error{{ form.errors|pluralize }} below.
</p>
{% endif %}
<form action={% url "sent" %} method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.songfile.label_tag }} {{ form.songfile.help_text }}</p>
<p>
<!--{{ form.songfile.errors }}-->
{{ form.songfile }}
</p>
<p><input type="submit" value="Upload" /></p>
</form>
forms.py-
class SendFileForm(forms.Form):
path = forms.CharField()
songfile = forms.FileField(label='Select a music file',help_text='max. 4 megabytes')
找了很多论坛都没能解决问题。 提前致谢!
最佳答案
注意:-此答案仅用于帮助您调试代码。
您可以直接在 View 中打印表单错误。
class YourFormView(generic.edit.CreateView):
def post(self, request, *args, **kwargs):
form = YourForm(request.POST)
for field in form:
print("Field Error:", field.name, field.errors)
关于html - form.is_valid() 返回 false (django)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20723646/
