How to open an uploaded file in another template - Django? - django

Question

my django app acts as an emailing service, emails that are sent are view-able and it's possible to send html emails. How do I display the html emails on the view-mail page rather than just displaying the name of the file ? (the following is the mail-view for an html email):
How would I display the actual html in the body of this page?
This is my views.py:
def outbox(request):
#Mail_Item.objects.all().delete()
if request.method == "POST" and request.POST.get('Username', False)!=False:
username = request.POST.get('Username')
password = request.POST.get('Password')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user, backend='django.contrib.auth.backends.ModelBackend')
print(username + " has logged in")
messages = Mail_Item.objects.filter(user=request.user.username)
args = {'messages':messages}
return render(request, 'outbox.html', args)
else:
return render(request, '404.html')
elif request.POST.get('Username', False) == False and request.POST.get('mail_body_field', False) == False:
pass
elif request.method == "POST" and request.POST.get('mail_subject_field')!=False:
subject = request.POST.get('mail_subject_field')
body = request.POST['mail_body_field']
file = ""
try:
file = request.FILES['filename']
except:
pass
print("sending mail:")
for i in range(1, len(Res)+1):
y = Res['ID' + str(i)].email
print("sent to " + y )
msg = EmailMessage(subject, body, 'email#example.com', [y])
msg.content_subtype = "html"
if (str(file)) != "" and (str(file))[-4:] != 'html':
msg.attach_file(str(file))
obj = Mail_Item(subject=subject, body=body, user=request.user.username, file_name=(str(file)))
obj.save()
print("email stored in database")
elif (str(file)) != "" and (str(file))[-4:] == 'html' :
uploaded_file = file
fs = FileSystemStorage()
fs.save((str(file)), uploaded_file)
html_message = render_to_string((str(file)), {'context': 'values'})
plain_message = strip_tags(html_message)
from_email = 'From <email2#example.com>'
mail.send_mail(subject, plain_message, from_email, [y], html_message=html_message)
obj = Mail_Item(subject=subject, body=body, user=request.user.username, file_name=(str(file)))
obj.save()
else:
obj = Mail_Item(subject=subject, body=body, user=request.user.username, file_name='None')
obj.save()
print("email stored in database")
#msg.send()
i += 1
messages = Mail_Item.objects.filter(user=request.user.username)
args = {'messages':messages}
return HttpResponseRedirect('../templates/outbox.html', args, request)
else:
print("pleeeeeaassee")
return render(request, '404.html')
messages = Mail_Item.objects.filter(user=request.user.username)
args = {'messages':messages}
return render(request, 'outbox.html', args)
def login_page(request):
if request.method == "POST":
username = request.POST['sign-up-name']
email = request.POST['sign-up-email']
password = request.POST['sign-up-password']
user = User.objects.create_user(username, email, password)
user.save()
print(username + " has been added to the user database.")
else:
pass
return render(request, 'login.html')
def signup_page(request):
return render(request, 'signup.html')
def mail_view(request, id=None):
if id:
email = Mail_Item.objects.get(id=id)
args = {'email':email}
else:
pass
return render(request, 'mail-view.html', args)
def log_out(request):
logout(request)
return render(request, 'log-out.html')
def delete(request):
Mail_Item.objects.filter(id=id).delete()
messages = Mail_Item.objects.filter(user=request.user.username)
args = {'messages':messages}
return render(request, 'outbox.html', args)
This is the code for my mail-view template where I'd like to place the html that is being sent:
<div class="mail-view">
<h4 class="m-0">{{ email.subject }}</h4>
<div class="divid"></div>
<div class="media">
<div class="media-left">
<div class="avatar avatar-lg avatar-circle">
<img class="img-responsive" src="{% static '../static/assets/images/221.jpg' %}" alt="avatar"/>
</div><!-- .avatar -->
</div>
<div class="media-body">
<div class="m-b-sm">
<h4 class="m-0 inline-block m-r-lg">
Access Bank
</h4>
</div>
<p><b>Attachment: </b>{{ email.file_name }}</p>
</div>
</div>
<div class="divid"></div>
<div class="row">
<div class="col-md-12">
<div class="m-h-lg lh-xl">
<p>{{ email.body }}</p>
</div>
</div>
</div>
</div>
Models.py:
from django.db import models
class Details(models.Model):
email = models.CharField(max_length=200)
def __str__(self):
return self.email
class Mail_Item(models.Model):
subject = models.CharField(max_length=200)
body = models.CharField(max_length=300)
time = models.DateTimeField(auto_now=True)
user = models.CharField(max_length=15)
file_name = models.CharField(max_length=100, null=True, default=None)
def __str__(self):
template = '{0.subject} {0.body} {0.time} {0.user} {0.file_name}'
return template.format(self)
