Re: Capture URL values in a CBV

[Dylan Reinhold]

Tim you want to use get_context_data to add more data into your context for
the template

def get_context_data(self, **kwargs):
# Call the base implementation first to get a context
context = super().get_context_data(**kwargs)
# You your stuff
context['my_pk'] = self.kwargs['pk']
return context


Then in your template you get get it as {{ my_pk }}
See
https://docs.djangoproject.com/en/3.0/topics/class-based-views/generic-display/#adding-extra-context

Re: Capture URL values in a CBV

[Tim Johnson]

OK. I am abandoning all pretext at self-sufficiency here. I have 
researched this for days, reviewed the links below and I still cannot 
resolve this issue.


Maybe someone besides Gavin has an idea of how to capture the pattern 
between angle brackets in a url conf into a class-based view.


I am sure the solution is very easy, but I obviously am missing something.

thanks

I gotta know. I'm a retired programmer with 19 years doing CGI. Wrote

I really want to know what is going on "under the hood" but I also

I'm building a website with django as an alternative to the original 
in Drupal because I want fine-grained control.


I hope that answers your question.



With the DetailView, fetching the object with the primary key is 
already handled for you, as you've seen the object will already be 
available in the template.


This website is very useful to know which functions are implemented 
in a class-based view, and which variables are available.

Adding the get_queryset method to the view doesn't work

How to modify messages displayed in Admin change page?

[Mark Phillips]

I have a model Document, and the admin can upload an image to a FileField.
When a document/image is successfully uploaded, I also save a sha256
"fingerprint" of the image to test if an admin tries to upload a duplicate
image. If a duplicate image is detected, I don't save the duplicate image
and display an error message to the admin through the messages framework.
However, I also get the message that the document was successfully
uploaded. How can I prevent this from happening?

My code in an abbreviated form:
class Document(Model):
document_id = models.AutoField(primary_key=True)
computed_sha256 = models.CharField(editable=False, max_length=64,
default="foobar")
storage_file_name = models.FileField('File name',
upload_to=settings.DOCUMENT_FOLDER_ORIGINALS,
default=settings.DEFAULT_IMAGE_XXXLARGE_PATH,)

class DocumentAdmin(admin.ModelAdmin):

def save_model(self, request, obj, form, change):
if form.is_valid():
if not change:
# Uploading one or more images
files = request.FILES.getlist('storage_file_name')
if files:
for f in files:
# Check if this file has been uploaded before by
checking the fingerprint
_file = form.cleaned_data["storage_file_name"]
sha256 =
image_processing_utils.compute_sha256(_file)
duplicate_files =
Document.objects.filter(computed_sha256 = sha256)
if len(duplicate_files) > 0:
messages.add_message(request, messages.WARNING,
'Uploading a duplicate of "%s" and it will not be saved' % f.name)
break;
# more image processing stuff
else:
# some more image processing stuff
obj.metadata = form.cleaned_data['metadata']
super().save_model(request, obj, form, change)

The attached image shows the problem.

Where can I find the message that the document was saved properly and
remove it from the messages list?

Thanks!

Mark

Re: problem with admin panel

[Andréas Kühne]

This sounds like you are having problems with the static files - check so
that you have run "manage.py collectstatic" correctly and that the command
works.

reg: CUstomizing User model

['Amitesh Sahay' via Django users]

Hi, 
I am creating the user signup form with the help of "UserCreationForm" and 
"User" model. So, whatever came in-built is working fine for me, I am able to 
successfully create the sign up and form and able to authenticate. So far so 
good. 
Now, I am trying to add a new "phone" field in the existing User model as per 
my customization plan. 
1) So, as per the user model customization process I make the entries in the 
models.py
from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver

class SignUp(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
Contact = models.TextField(max_length=500, blank=True)


@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
SignUp.objects.create(user=instance)

@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
instance.profile.save() 2) python manage.py makemigrations3) python 
manage.py migrate4) I added the newly defined model in my forms.py as below:
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from django import forms
from  .models import SignUp

class SignUpForm(UserCreationForm): # Default signup page layout
email = forms.EmailField()
first_name = forms.CharField(max_length=100)
last_name = forms.CharField(max_length=100)

class Meta:
model = User
fields = ('username', 'first_name', 'last_name', 'email', 'password1', 
'password2')


class SignUpPage(UserCreationForm): # Newly added model
phone = forms.CharField(max_length=10)
class Meta:
model = User
fields = ('phone', )But I am not sure if I needed to create a separate 
class for that, or I should add the extra field in the same default sign up 
page layout. Below is my views.py for the default layout
from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login, logout
from django.contrib import messages
#from django.contrib.auth.forms import UserCreationForm
from .forms import SignUpForm, SignUp

def home(request):
   return render(request, 'authenticate\home.html', {})

def login_user(request):
   if request.method == 'POST':
  username = request.POST['username']
  password = request.POST['password']
  user = authenticate(request, username=username, password=password)
  if user is not None:
 login(request, user)
 messages.success(request, ('login success'))
 return redirect('home')
  else:
 messages.success(request, ('error while login, please try again'))
 return redirect('login')
   else:
  return render(request, 'authenticate\login.html', {})

def logout_user(request):
   logout(request)
   messages.success(request, ('logout successful'))
   return redirect('home')


def register_user(request):
   if request.method == "POST":
  form = SignUpForm(request.POST)
  if form.is_valid():
 form.save()
 username = form.cleaned_data['username']
 password = form.cleaned_data['password1']
 user = authenticate(request, username=username, password=password)
 login(request, user)
 messages.success(request, ('Registration successful'))
 return redirect('home')
  else:
 form = SignUpForm()
  return render(request, 'authenticate\\register.html', context={'form': 
form})

As one can see that I have imported the required class from forms.py, but I am 
not able to recognize the place where I can call it in "register_user" in 
views.py.Please help. Also correct if I have done anything wrong.

Regards,
Amitesh

Re: Cannot Redirect to other page

[pui hei Li]

Thank you so much, I have fixed the problem, now I can redirect to the 
pages I want.

*morse_logs/game2.html*

{% extends "morse_logs/base.html" %}

{% block content %}
GAME 2

GAME 2
2 + 2 = ?

{% csrf_token %}




{% endblock content %}


*morse_logs/views.html*

@login_required()
def game2(request):
"""The Game2 page"""
if request.method == "GET":
return render(request, 'morse_logs/game2.html')
elif request.method == "POST":
if request.user and not request.user.is_anonymous:
user = request.user

user_score, created = userScore.objects.get_or_create(user=user)

ans2 = request.POST.get('ans2', '') #fetch the POST data from template
if ans2 == '':
ans2 = 0

ans2 = int(ans2)
if ans2 == 4:
# user's score declared in model increase 5points
# display correct and 5 points added to user
user_score.score += 5
user_score.save()
return redirect(reverse('morse_logs:correct'))
else:
# user's score declared in model has no point
# display incorrect and 0 point added to user
return redirect(reverse('morse_logs:incorrect'))

Re: Models as choices

[Gavin Wiener]

If you're serializing as JSON, that primary key is literally just integer 
then, and the foreign key relationship requires an instance of that foreign 
key. So you'll need to fetch an instance of the object first.

I've had this issue before, that's how I resolved it.
