Django 3.0: Unable to get username in template - django

I have issue is that in template, I automatically get access of username of Superuser (if that is logged-in) but not username of user based on Buyer (Model). User is getting registered and also can login (I can see it in database). But in template I am unable to get username of user other than superuser. I don't what i am missing here. So i am putting all code of view.py here. Also after user logging he sees bookrepo:home and i am using user logic in header.html (bookrepo:home extends header.html)
I have model named Buyer in models.py file. And based on this model, two modelForm has made.
This is code of model.py
class Buyer(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
user = models.OneToOneField(User, on_delete=models.DO_NOTHING)
# additional attributes
contact = models.CharField('Contact #', max_length=16, unique=True, validators=[
RegexValidator(
regex=r'^\+?1?\d{9,15}$',
message="Phone number (Up to 15 digits) must be entered in the format: '+923001234567'."
),
], )
devices = models.CharField('Devices', unique=False, max_length=115, blank=True)
picture = models.ImageField(upload_to=profile_pic_path, null=True,blank=True)
def __str__(self):
return "{} {}".format(self.user.first_name, self.user.last_name)
class Meta:
get_latest_by = '-user.date_joined'
This is code of modelForms
class RegistrationForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput())
confirm_password = forms.CharField(widget=forms.PasswordInput())
class Meta():
model = User

'password')
def clean(self):
cleaned_data = super(RegistrationForm, self).clean()
password = cleaned_data.get("password")
confirm_password = cleaned_data.get("confirm_password")
if password != confirm_password:
raise forms.ValidationError(
"Password and Confirm Password does not match"
)
class RegistrationFormPlus(forms.ModelForm):
class Meta():
model = Buyer
fields = ('contact',)
This is code of header.html (NOT the home.html)
{% if user.is_authenticated %}
<a class="nav-link" href="{% url 'bookrepo:logout' %}">Logout</a>
<h2>Welcome {{ user.username }}!</h2>
{% else %}
<a class="nav-link" href="{% url 'bookrepo:user_login' %}">Login</a>
{% endif %}
This is code of views.py
def home(req):
bookz = Book.objects.order_by('title')
var = {'books': bookz, 'range': 10}
return render(req, 'bookrepo/home.html', context=var)
def registration(request):
registered = False
if request.method == 'POST':

print("Someone tried to login and failed.")
print("They used username: {} and password: {}".format(username, password))
return HttpResponse("Invalid login details supplied.")
else:
return render(request, 'bookrepo/login.html', {})

You should use {{ buyer.user.username }} in your template to show the username of a user.

You are trying to extend your django user framework with a One To One Field . new extended Django Model used to store the extra information that relates to the User Model. {{user.username}} gives the username from session.
use this code to authenticate users don't forgot to import
from django.contrib.auth.models import User,auth
def login(request):
if request.method == "POST":
username = request.POST['username']
password = request.POST['password']
user=auth.authenticate(username=username,password=password)
if user is not None:
auth.login(request,user)
return redirect('index')
else:
messages.info(request,'invalid user')
return redirect('login')
else:
return render(request,"login.html")

Email forms do not match in Django Custom-User registration

I'm setting up a custom-user registration form to create an account on my Django project. I feel I'm missing something very simple that keeps me from registering for some reason.
My registration form demands 4 fields to be filled before a new user can register. Of these 4 fields, two are just a confirmation of the email address.
Here is a copy of my form.py:
class UserRegisterForm(forms.ModelForm):
username = forms.CharField(label='Username')
email = forms.EmailField(label='Email Address')
email2 = forms.EmailField(label='Confirm Email')
password = forms.CharField(widget=forms.PasswordInput)
class Meta:
model = CustomUser
fields = ['username', 'email', 'email2', 'password']
def clean_email(self):
email = self.cleaned_data.get('email')
email2 = self.cleaned_data.get('email2')
if email != email2:
raise forms.ValidationError("Emails do not match")
And here is a copy of my view.py:
def register_view(request):
next = request.GET.get('next')
form = UserRegisterForm(request.POST or None)
if form.is_valid():
user = form.save(commit=False)
password = form.cleaned_data.get('password')
user.set_password(password)
user.save()
new_user = authenticate(username=user.username, password=password)
login(request, new_user)
if next:
return redirect(next)
return redirect('/home/')
context = {'form':form, "title":"register"}
return render(request, "register.html", context)
Here is my html file:
<h2><center><font color="white">Register Here:</font></center></h2>
<form method="POST"><center>
{% csrf_token %}
{{form}}
<input type="submit" />
</center></form>
Whenever I try to register as a new user, my form validation error is raised as is says that my two emails do not match (I copy-paste them to make sure they are identical).
I feel I'm missing something that is right under my nose...
Cheers to all of you and thank you very much.
try this
def register_view(request):
next = request.GET.get('next')
form = UserRegisterForm(request.POST or None)
if form.is_valid():
email = form.cleaned_data.get('email')
email1 = form.cleaned_data.get('email1')
if email1 == email
user = form.save(commit=False)
password = form.cleaned_data.get('password')
user.set_password(password)
user.save()
new_user = authenticate(username=user.username, password=password)
login(request, new_user)
if next:
return redirect(next)
else:
….
def clean(self):
cleaned_data = super(UserRegisterForm, self).clean()
email = cleaned_data.get('email')
email2 = cleaned_data.get('email2')
if email != email2:
self.add_error("email", "Emails do not match")
The problem is that in clean_email method you have email2 to be always None. To compare two or more fields use clean method

make sure to define the right user model to django settings, add
# AUTH_USER_MODEL = 'YOUR_APP_NAME.YOUR_CUSTOM_USER_MODEL'
to your django settings .like # AUTH_USER_MODEL = 'users.User'
and you need to write an abstract user model .
from django.contrib.auth.models import AbstractUser
class RightsSupport(models.Model):
class Meta:
managed = False # No database table creation or deletion \
# operations will be performed for this model.
permissions = (
("add_user", "Can Create User"),

also update your view, that code has a huge mistake on it . you forget to close docstring .

Django - Template displays edited user context info despite ValidationError

Hi I'm working on a form to edit a user's profile. It properly updates the fields upon successful submission without any validation errors. The problem I'm having is that if the form does return a validation error upon submission and I've changed the name on the form, the template will display this new name instead of the old name. I'm assuming this is because it uses the user context provided by the POST request. Is there any way to properly display the user's old name until the form is actually successfully submitted? Below is my code.
forms.py
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

Could you please help me on?
Thanks!
You can request the email instead of username to the user in your login form in order to use it for loggin him, then just generate a username for that user, you can do it using his email or name.
EDIT:
You only need to generate an username. Let's say that you are requesting name and last name to the user. Let's create a method to generate it.
def generate_username(first_name, last_name):
username = '%s.%s' % (first_name.lower(), last_name.lower())
username = '{:.29}'.format(username)
counter = User.objects.filter(first_name=first_name,last_name=last_name).count()
if counter > 0:
username += '%s' % (counter + 1)
return username
Then you can use it on your view.
user = user_form.save(commit=False)
user.set_password(user.password)
user.username = generate_username(first_name, last_name)
.....
If you don't want to request first name or last name, you can generate the username using his email too.

Django username already taken error

I have an form that allows a user to create a user account.The problem is , whenever a user submit a username that already been taken through the system . The form doesn't raise an error but it does raise an error when a field is missing. Can someone kindly help me
def Registration(request):
form = UserRegistration()
if request.method =='POST':
form = UserRegistration(request.POST)
if form.is_valid():
user = User.objects.create_user(
username=form.cleaned_data['username'],
email=form.cleaned_data['email'],
password=form.cleaned_data['password']
)
user.is_active = True
user.save()
return render(request,'choose.html',{'form':form})
return render(request, 'register.html', {'form': form},)
My forms.py
class UserRegistration(forms.Form):
username = forms.CharField()
email = forms.EmailField(error_messages={'required':'Error Missing Field , Please Fill this Field'})
password = forms.CharField(
widget=forms.PasswordInput(render_value=False)
)
def clean(self):
cleaned_data = super(UserRegistration, self).clean()
username = cleaned_data.get("username")
password = cleaned_data.get("password")
user = User.objects.filter(username=username)
if user :
raise forms.ValidationError(
"That user is already taken , please select another ")
return cleaned_data
My template
<form method ="POST">
{% csrf_token %}
<span id="error">{{form.username.errors}}</span>
<span id="error2">{{form.email.errors}}</span>
<span id="error3">{{form.password.errors}}</span>
{{form.username}}
{{form.email}}
{{form.password}}
<input type = "submit" value= "save" id="box2"/>
</form>
You should use the exists[0] method:
user = User.objects.filter(username=username)
if user.exists():
raise forms.ValidationError("That user is already taken")
Edit:
Try using the clean_username method:
class UserRegistration(forms.Form):
....
def clean_username(self):
username = self.cleaned_data['username']
if User.objects.filter(username=username).exists():
raise forms.ValidationError("That user is already taken")
return username
You could add a Test to make sure it works:
from django.test import TestCase
class TestUniqueUsername(TestCase):
def test_unique_username(self):
User.objects.create(username='test', password='test', email='test#django.com')
form = UserCreationForm(data={'username': 'test'})
self.assertFalse(form.is_valid())
[0] https://docs.djangoproject.com/en/dev/ref/models/querysets/#django.db.models.query.QuerySet.exists
Try this code
class UserRegistration(forms.Form):
username = forms.CharField()
email = forms.EmailField(error_messages={'required':'Error Missing Field , Please Fill this Field'})
password = forms.CharField(
widget=forms.PasswordInput(render_value=False)
)
def clean_username(self):
cleaned_data = self.cleaned_data
username = cleaned_data.get("username")
user = User.objects.filter(username=username)
if user.count() > 0:
raise forms.ValidationError("That user is already taken , please select another ")
return username
This will do the trick.
