Issue
Here form is submitted via POST method but password given in the input field of type=password not assigning to ‘upassword’ given in the userregister function.When I print the ‘upassword’ it gives an output "None".Also it gives an error like this when I give JAVASCRIPT validation.
Internal Server Error: /Salon/Registration/

Solution
You access password and cpassword while the name you set for these fields is actually pass and cpass:
<input type="password" class="form-control" id="password" name="pass" placeholder="Password">
<input type="password" class="form-control" id="cpassword" name="cpass" placeholder="Confirm Password">
It will work if you change your code to use the correct field names:
spassword = request.POST.get('pass')
scpassword = request.POST.get('cpass')
You could have spotted that by looking at the actual data that is getting sent in the POST request, so my suggestion for the future is to always first inspect your request in the browser’s devtools.
