How to show the validation error in a Django form? - django

Question

I am new to Django. I am trying to make a simple form to match the password. However, when I enter different passwords and press the Save button I get a cleared form instead of showing the validation error.
Here newuser.html:
{% block content %}
<form method="POST">
{% csrf_token %}
<table>
{{frmNewUser.as_table}}
{% for error in frmNewUser.password.errors %} {% comment %} I tried frmNewUser.non_field_errors too {% endcomment %}
<p>{{error}}</p>
{% endfor %}
</table>
<input type="submit" name="Save" value="Save" colspan=2>
</form>
{% endblock content %}
Here forms.py:
class NewUserFrom(forms.Form):
username = forms.CharField(max_length=50, widget=forms.TextInput)
password = forms.CharField(widget=forms.PasswordInput)
confirm_password = forms.CharField(label="Confirm password", widget=forms.PasswordInput)
name = forms.CharField(max_length=50, widget=forms.TextInput)
email = forms.EmailField(max_length=50, widget=forms.EmailInput)
def clean(self):
cleaned_data = super().clean()
pwd = cleaned_data.get('password')
cof_pwd = cleaned_data.get('confirm_password')
if pwd and cof_pwd:
if pwd != cof_pwd:
raise forms.ValidationError('Password is not match.')
return super().clean()
Here views.py:
from django.shortcuts import render
from django.http import HttpResponse, request
from django.db import connection
from django.contrib.auth.decorators import login_required
import pyodbc
from .forms import NewUserFrom
def newUser(request):
form = NewUserFrom(request.POST)
if not form.is_valid():
return render(request,'login/newuser.html', {'frmNewUser':NewUserFrom})
return render(request, "login/welcome.html")

Answer 1

Try following this article, it helped when i had a similar problem

Answer 2

in the newUser function
def newUser(request):
form = NewUserFrom(request.POST)
if not form.is_valid():
return render(request,'login/newuser.html', {'frmNewUser':NewUserFrom})
return render(request, "login/welcome.html")
the return value in the if statement should be changed from {'frmNewUser':NewUserFrom}) to {'frmNewUser':form})
