Я пытаюсь создать FileField в своих формах и, не сохраняя файл локально, добавить файл (в виде вложения) в электронное письмо и отправить его. Часть кода электронной почты работает нормально, но когда я добавляю FileField, он показывает мне ошибку «объект 'str' не имеет атрибута 'get'», и я изо всех сил пытаюсь понять, в чем проблема.
Посмотреть:
def print(request):
if request.method == 'POST':
form = PrintForm(data=request.POST, request = request)
#print(request.FILES)
if form.is_valid():
contact_name = request.POST.get('contact_name', '')
contact_email = request.POST.get('contact_email', '')
form_content = request.POST.get('content', '')
supervisor = form.cleaned_data['supervisor']
template = get_template('threeD/email/contact_template_for_printing.txt')
context = Context({
'contact_name': contact_name,
'supervisor': supervisor,
'contact_email': contact_email,
'form_content': form_content,
})
content = template.render(context)
subject = "New message"
try:
email = EmailMessage(
subject,
content,
contact_email,
[supervisor],
headers={'Reply-To': contact_email}
)
if request.FILES:
#uploaded_file = request.POST.get('file')
uploaded_file = request.FILES['stl_file'] # file is the name value which you have provided in form for file field
email.attach('uploaded_file.name, uploaded_file.read(), uploaded_file.content_type')
email.send()
except:
return "Attachment error"
messages.success(request, "Thank you for your message.")
return redirect('/index/print/')
else:
form = PrintForm(request=request)
context_dict = {}
context_dict['printers'] = Printer.objects.all()
context_dict['form'] = form
return render(request, 'threeD/print.html', context_dict)
форма:
class PrintForm(forms.Form):
contact_name = forms.CharField(required=True)
contact_email = forms.EmailField(required=True)
supervisor = forms.ChoiceField(
choices=[(str(sup.email), str(sup.name)) for sup in Supervisors.objects.all()]
)
stl_file = forms.FileField(required=False)
stl_file.help_text = "Upload your file as .STL format. If you have more than one file, " \
"make a .zip and upload them all at once"
content = forms.CharField(
required=True,
widget=forms.Textarea
)
def __init__(self, *args, **kwargs):
self.request = kwargs.pop("request")
super(PrintForm, self).__init__(*args, **kwargs)
self.fields['contact_name'].label = "Your name:"
self.fields['stl_file'].label = "Choose your design file:"
вот фрагмент кода HTML, где я вызываю форму:
<div class="panel-body">
<form role="form" action="" method="post" enctype="multipart/form-data">
{% csrf_token %}
{% load bootstrap %}
{{ form|bootstrap }}
<div class="text-center">
<button type="submit" class="btn btn-primary">
<span class="glyphicon glyphicon-send"></span>
Send a message
</button>
</div>
</form>
</div>
