Gmail sending with attachment in Django - html

Question

I am trying to send Gmail with attachments also in Django.
here my views.py:
def index(request):
if request.method != 'POST':
form = EmailForm()
context = {'email_form': form}
return render(request, 'app/index.html', context)
form = EmailForm(request.POST, request.FILES)
if form.is_valid():
subject = form.cleaned_data['subject']
message = form.cleaned_data['message']
email = form.cleaned_data['email']
attach = request.FILES['attach']
try:
mail = EmailMessage(subject, message, settings.EMAIL_HOST_USER, [email])
mail.attach_file(attach.name, attach.read(), attach.content_type)
mail.send()
context = {'message': 'email sended'}
print("email sended")
return render(request, 'app/email_template.html', context)
except:
context = {'message': 'Either the attachment is too big or corrupt'}
print("Either the attachment is too big or corrupt")
return render(request, 'app/index.html', context)
context = {'message': 'Unable to send email. Please try again later'}
return render(request, 'app/index.html', context)
forms.py:
class EmailForm(forms.Form):
email = forms.EmailField()
subject = forms.CharField(max_length=100)
attach = forms.Field(widget = forms.FileInput)
message = forms.CharField(widget = forms.Textarea)
template:
<div class="container-fluid">
<div class="col-xl-4">
<h1>Welcome in django's world</h1>
{{message}}
<form method="POST" action ="." enctype="multipart/form-data">
{% csrf_token %}
<br></br>
{{email_form.as_p}}
<label> </label><label> </label><label> </label>
<input type ="submit" name = "send" value = "Send"/>
</form>
</div>
</div>
Now each and every time I tried to sent mail, it shows Either the attachment is too big or corrupt, which means it goes by the except: block, instead of the try block.I just print the exception msg, it says
__init__() takes from 1 to 2 positional arguments but 5 were given
Now how can I solve this problem such that Gmail will be sent successfully?
