ValueError at /signup/ The given username must be set

问题

so basically I have been building this blogging website and now I am stuck at this point of the Signup process, the whole work is done using django

views.py:

def handleSignup(request):
    if request.method == 'POST':
        # getting user parameters
        username =  request.POST.get('username')
        fname =  request.POST.get('fname')
        lname =  request.POST.get('lname')
        email =  request.POST.get('email')
        pass1 =  request.POST.get('pass1')
        pass2 =  request.POST.get('pass2')
        # fname = request.POST['fname']
        # lname = request.POST['lname']
        # email = request.POST['email']
        # pass1 = request.POST['pass1']
        # pass2 = request.POST['pass2']
        

    # creating users

        myuser = User.objects.create_user(username = username, email = email, password = pass1)
        myuser.first_name = fname
        myuser.last_name = lname
        myuser.save()
        messages.success(request, 'your account have been successfully created!')
        
        return redirect(request, 'home')

    else:
        return HttpResponse("error 404 not found")

form in base.html:

<form action="/signup/" method="post">

            <div class="form-group">
              <label for="username">Username</label>
              <input type="text" class="form-control" id="username" placeholder="choose a unique username">
            </div>

            <div class="form-group">
              <label for="fname">Firstname</label>
              <input type="text" class="form-control" id="fname" placeholder="First Name">
            </div>

            <div class="form-group">
              <label for="lname">Lastname</label>
              <input type="text" class="form-control" id="lname" placeholder="Last Name">
            </div>

            <div class="form-group">
              <label for="email">Email</label>
              <input type="email" class="form-control" id="email" placeholder="email@example.com">
            </div>

            <div class="form-group">
              <label for="pass1">Choose Password</label>
              <input type="password" class="form-control" id="pass1">
            </div>

            <div class="form-group">
              <label for="pass2">Confirm password</label>
              <input type="password" class="form-control" id="pass2">
            </div>
            {% csrf_token %}
            <button type="submit" class="btn btn-primary">Submit</button>

          </form>

now I am getting this error:

as you guys can see in views.py I have already tried fname = request.POST['fname'] but then I was getting the MultiValueDictKeyError for which I searched on net and got a suggestion to use request.POST.get(' ') and after using that I am facing the above error

You have to add name to your input field in HTML:

<div class="form-group">
      <label for="username">Username</label>
      <input type="text" class="form-control" id="username" name="username" placeholder="choose a unique username">
</div>

You are not giving name in any of the input field. Server takes data from the form on the basis of name, but not id. So, provide name to each input tag in your form. And, you are good to go.
