我尝试使用Django将文件上传到服务器,但form.is_valid
始终返回Flase。然后我输出了如下所示的表格值。
在views.py中打印表单
<tr><th><label for="id_country">country:</label></th><td><input type="text" name="country" value="DE" required id="id_country" maxlength="200" /></td></tr>
<tr><th><label for="id_email">email:</label></th><td><input type="email" name="email" value="123456789@example.com" required id="id_email" /></td></tr>
<tr><th><label for="id_filetoupload">fileToUpload:</label></th><td><ul class="errorlist"><li>This field is required.</li></ul><input type="file" name="filetoupload" required id="id_filetoupload" /></td>
</tr>
form.py
from django import forms
class UserInfo(forms.Form):
country = forms.CharField(label='country', max_length=200)
email = forms.EmailField(label='email')
filetoupload = forms.FileField(label='fileToUpload')
urls.py
from django.conf.urls import url
from loadfileweb.views import receiveinfo
urlpatterns = [
url(r'^home/', receiveinfo),
url(r'^home/submit', receiveinfo)
]
views.py
def receiveinfo(request):
if request.method == 'POST':
form = UserInfo(request.POST, request.FILES)
print "form info"
print form
print form.is_valid()
if form.is_valid():
# process the data in form.cleaned_data as required
country = form.cleaned_data['country']
email = form.cleaned_data['email']
print email
print "------------ get email -----------"
# redirect to a new URL:
return HttpResponse('/thanks/')
else:
print "----- form isn't valid -------"
return render(request, 'home.html', {'form': form})
else:
print "--------- request.method != 'POST'------------"
form = UserInfo()
return render(request, 'home.html', {'form': form})
home.html的
<form class='UserInfo' action="submit" method="post" enctype="multipart/form-data">{% csrf_token %}
E-mail: <input type="email" name="email" autofocus><br>
{{ form.email.errors}}<br>
Country: <input list="countrycode" name="country">
{{ form.country.errors}}<br>
<datalist id="countrycode">
<option value="DE">
<option value="ES">
<option value="FR">
<option value="IT">
<option value="UK">
<option value="JP">
<option value="CA">
<option value="USA">
</datalist>
<br>
Select a file to upload:
<input type="file" name="fileToUpload" id="fileToUpload" ><br>
{{ form.filetoupload.errors}}<br>
<input type="submit"><br>
</form>
我在谷歌和许多论坛上搜索过但仍有问题。希望对你有所帮助,谢谢!

1.您尚未保存表格。 你可以试试:
if form.is_valid():
temp = form.save(commit=False)
country = form.cleaned_data['country']
email = form.cleaned_data['email']
temp.save()
return HttpResponse('/thanks/')

1)使文件字段可选 - 您必须将表单中的filetoupload字段设置为required=False
非强制性,或者在提交之前上传文件!
因为很明显,您已共享的views.py中的This field is required.
中包含print forms
2)要使您的文件字段成为必填项,您需要修改表单中的filetoupload
以匹配html元素的name属性,反之亦然!
class UserInfo(forms.Form):
country = forms.CharField(label='country', max_length=200)
email = forms.EmailField(label='email')
filetoUpload = forms.FileField(label='fileToUpload')
