name 'user' is not defined-CodePudding

I'm trying to make a custom registration page without using usercreationform i've made the model and imported it but when i run it I keep encountering this error NameError at /register name 'user' is not defined the line in particular is:
if user.password != user.repassword:

and i tried changing the method to GET instead of POST and i got a different error MultiValueDictKeyError 'fname'

views.py

from django.shortcuts import render,redirect
from .models import User
from django.contrib import messages




def home(request):
    return render(request, 'home.html')


def register(request):
    global user
    if request.method == 'POST':
        user = User()
        user.fname = request.POST['fname']
        user.lname = request.POST['lname']
        user.email = request.POST['email']
        user.password = request.POST['password']
        user.repassword = request.POST['repassword']

    if user.password != user.repassword:
        return redirect("register")
    elif user.fname == "" or user.password == "" :
        messages.info(request,f"some fields are empty")
        return redirect("register")
    else:
        user.save()
    return render(request, 'register.html')

CodePudding user response：

Is this what you want?:

def register(request):
    user = request.user
    if request.method == 'POST':
        user = User()
        user.fname = request.POST['fname']
        user.lname = request.POST['lname']
        user.email = request.POST['email']
    ....
    ....

CodePudding user response：

You should do something if the request method is not POST:

from django.core.exceptions import BadRequest

def register(request):
    if request.method == 'POST':
        user = User()
        user.fname = request.POST['fname']
        user.lname = request.POST['lname']
        user.email = request.POST['email']
        user.password = request.POST['password']
        user.repassword = request.POST['repassword']
       
        if user.password != user.repassword:
            return redirect("register")
        elif user.fname == "" or user.password == "" :
            messages.info(request,f"some fields are empty")
            return redirect("register")

        user.save()
        return render(request, 'register.html')
    else:
        raise BadRequest()  # Or do something else

This view will work with POST requests.
