im currently facing the problem that i want to call a view from another app (accounts app which holds the user model) within my main app (a blog app).
this is the error i get:
django.core.exceptions.FieldError: Unknown field(s) (username) specified for User
urls.py
...
from quickblog import views as core_views
from accounts import views as views_accounts
...
url(r'^myaccount/$', views_accounts.view_profile, name='myaccount'),
views.py (accounts app):
from django.shortcuts import render, redirect
from django.urls import reverse
from accounts.forms import (
RegistrationForm,
EditProfileForm
)
from django.contrib.auth.models import User
from django.contrib.auth.forms import PasswordChangeForm
from django.contrib.auth import update_session_auth_hash
def register(request):
if request.method == 'POST':
form = RegistrationForm(request.POST)
if form.is_valid():
form.save()
return redirect(reverse('accounts:home'))
else:
form = RegistrationForm()
args = {'form': form}
return render(request, 'reg_form.html', args)
def view_profile(request, pk=None):
if pk:
user = User.objects.get(pk=pk)
else:
user = request.user
args = {'user': user}
return render(request, 'profile.html', args)
def edit_profile(request):
if request.method == 'POST':
form = EditProfileForm(request.POST, instance=request.user)
if form.is_valid():
form.save()
return redirect(reverse('accounts:view_profile'))
else:
form = EditProfileForm(instance=request.user)
args = {'form': form}
return render(request, 'edit_profile.html', args)
def change_password(request):
if request.method == 'POST':
form = PasswordChangeForm(data=request.POST, user=request.user)
if form.is_valid():
form.save()
update_session_auth_hash(request, form.user)
return redirect(reverse('accounts:view_profile'))
else:
return redirect(reverse('accounts:change_password'))
else:
form = PasswordChangeForm(user=request.user)
args = {'form': form}
return render(request, 'change_password.html', args)
This is my first django app, is there maybe anything i need to know about linking two apps within one project?
thanks

hello guys i am working on form i didint find how to get instance in the form. This is not a model form
def form(request):
if request.method == 'POST':
form = Form(request.POST)
if form.is_valid():
else:
form = Form()
return render(request, 'app/form.html', {'form': form})
You should have a form class something like below:
forms.py
from django import forms
class NameForm(forms.Form):
your_name = forms.CharField(label='Your name', max_length=100)
Now To handle the form we need to instantiate it in the view for the URL where we want it to be published:
views.py
from django.http import HttpResponseRedirect
from django.shortcuts import render
from .forms import NameForm
def get_name(request):
if request.method == 'POST':
form = NameForm(request.POST)
if form.is_valid():
# process the data as required
# ...
# redirect to a new URL:
return HttpResponseRedirect('/thanks/')
else:
form = NameForm()
return render(request, 'name.html', {'form': form})
Refer the Django documentation for more details.
https://docs.djangoproject.com/en/3.0/topics/forms/
from django.shortcuts import render, redirect
from django.contrib import messages
from .forms import UserRegisterForm, UserUpdateForm, ProfileUpdateForm
from django.contrib.auth.decorators import login_required
def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
form.save()
messages.success(request, f'Your account has been created. Log In to continue.')
return redirect('login')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form': form})
This is the code when I run it I get an error. But that error shouldn't be there since I am not overriding the the save() method. please help.
try to get each form input one by one and then save the form. for example:
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
data = YourModelName()
data.input1 = form.cleaned_data['input1']
data.input2 = form.cleaned_data['input2']
# ...
form.save()
messages.success(request, 'Your account created. You can now Login.')
return redirect('login')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form': form})
I have a feeling that you are doing Corey Schafer's Django tutorial. If so, other users have had the same problem, which is discussed here:
Django - TypeError - save() got an unexpected keyword argument 'force_insert'
The issue lies in overriding the save method in your Profile model
my views.py:
from django.http import HttpResponse
from django.shortcuts import render, render_to_response
from django.contrib.auth import login, authenticate
from django.contrib.auth.models import User
from django.shortcuts import render
from django.views.generic import View
from .forms import LoginForm, RegistrationForm
class Login(View):
form_class = LoginForm
initial = {'key': 'value'}
template_name = 'web/login.html'
def get(self, request):
form = self.form_class(initial=self.initial)
return render(request, self.template_name, {'form': form})
def post(self, request):
if request.method == 'POST':
form = self.form_class(initial=self.initial)
if form.is_valid():
email=form.cleaned_data['email']
password=form.cleaned_data['password']
auser = User.objects.get(email=email)
username = auser.username
buser = authenticate(username, password)
if buser:
if buser.is_active:
login(request, buser)
return HttpResponse('Good to Go...')
else:
return HttpResponse('your account is disabled...')
else:
print "Invalid login details: {0}, {1}".format(email, password)
HttpResponse('invalid login details...')
else:
return HttpResponse('Form is not valid!')
else:
form = self.form_class()
Here above I'm trying to login a user using email as unique field in class based views. But It raises 'Form is not valid!' as I specified in my views. I don't know what's going wrong with it exactly. Please Help me how to fix it?
Thanks in Advance
You need to change the post method of this class:
def post(self, request):
if request.method == 'POST':
form = self.form_class(data=self.request.POST)
if form.is_valid():

I am getting this error, I tried working on it a lot but cannot understand whats wrong.
I am basically trying to make a signup registration that has a couple of forms to be filled

Its HttpResponseRedirect not HttpRequestRedirect.
Change this return HttpRequestRedirect('/profile/') to return HttpResponseRedirect('/profile/')
P.S. Never use hardcoded urls in your code, use Reverse Resolution of URLs
I hope this is a good first question. I've been trying to DRY out my Django code, but unfortunately I keep getting hit with several errors! (Forgive me if I don't post the code with problems - I'll just post the code that works) I've tried using #decorators, and also putting a view within a view. Please help me!

But of course any more suggestions would be appreciated! Thank you so much!

Use login_required decorator (docs)
Use modelforms for editing/creating models. (docs)
If you need to just pass something to template, use direct_to_template generic view (docs)
You can use #login_required decorator for that. You can find out more at Django documentation: http://docs.djangoproject.com/en/dev/topics/auth/#django.contrib.auth.decorators.login_required.
Please describe any problems that you are experiencing.
