Just figured out the problem in case someone has read it. The system uses [ user_id, user_name ] as choices, not [ User instance, user_name ].

Hello people, has anyone here managed to create user profiles while using Django allauth for authentication. I am having challenges with user has no profile errors and RelatedObjectDoesNotExist a yet I have a Profile model with OnetoOne relationship with User model and a profile view plus use of Django signals for profile creation and saving

Users/views.py

`views.py

from django.shortcuts import render, redirect
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from .forms import ProfileUpdateForm

@login_required
def profile(request):
if request.method == 'POST':
p_form = ProfileUpdateForm(request.POST,
request.FILES,
instance=request.user.profile)
if p_form.is_valid():
p_form.save()
messages.success(request, f'Your account has been updated!')
return redirect('profile')

else:
    p_form = ProfileUpdateForm(instance=request.user.profile)

context = {
    'p_form': p_form
}

return render(request, 'profile.html', context)

`

MODELS.PY
`
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
image = models.ImageField(default='default.jpg', upload_to='profile_pics')
role = models.CharField(max_length=25,choices=role, default='Freelancer')

def __str__(self):
    return f'{self.user.username} Profile'

`

SIGNALS.PY
`
@receiver(post_save, sender=settings.AUTH_USER_MODEL)
def create_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
profile.save()

@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
instance.profile.save()

@jameskomo From my experience I recommend thick Form or Serializer, but not implement signal

Does anyone know how to query another model based on Foreign Key? Say I have a Project model that is a FK in task model and I want to generate all the task_names by querying the Task model and only see tasks applicable to a specific project?

Tried doing this and it is not working project_tasks=Task.objects.filter(project_id__in=Project.objects.all()).order_by('latest_submission_time')

Hi everyone! I’m a django beginner (generally a beginner dev)
I have a question. I’m working through yet another guided project. This time Django Girls. In other projects, everyone simply put the app name into settings.py file, in INSTALLED_APPS. Django Girls did ‘blog.apps.BlogConfig’. What does the .app.BlogConfig part change? I assume it must be created as it’s a custom name, but is there any difference if I just put an app name?
So in this case ‘blog’ vs. 'blog.apps.BlogConfig'

I have a dictionary which contains one item (“current_location”, which is a nested dict) and I would like to access that nested dict. However, I cannot use the key as the code will break if a different key is passed, e.g. “different_location".

How can I access the first item in a dictionary without using a key? The dict looks like this:

{'current_location': {'date': '2020-01-27T10:28:24.148Z', 'type_icon': 'partly-cloudy-day', 'description': 'Mostly Cloudy', 'temperature': 68.28, 'wind': {'speed': 10.48, 'bearing': 178, 'gust': 12.47}, 'rain_prob': 0.02, 'latitude': '-33.927407', 'longitude': '18.415747', 'request_id': 31364, 'request_location': 'Current location'}}

Got it. I used dict[next(iter(dict))]

Anyone who is familiar with using set.all in django in One-to-many relationship tables?

I have these two models

class Project(models.Model):
    project_name = models.CharField(max_length=100, blank=False)
    description = models.TextField(max_length=500, default=None)
    postedOn = models.DateTimeField(auto_now_add=True, blank=True)
    Owner = models.ForeignKey(User, on_delete=models.CASCADE)
    isCompleted = models.BooleanField(default=False)
    deadline = models.DateTimeField(blank=True, null=True)
    task_count = models.IntegerField(default=0)
    attachments=models.FileField(default='Project Attachments', upload_to='tasks_docs', validators=[validate_file_extension])


    def __str__(self):
        return self.project_name

class Task(models.Model):
    task_name = models.CharField(max_length=50, blank=False)
    addedOn = models.DateTimeField(auto_now_add=True, blank=True)
    project = models.ForeignKey(Project, on_delete=models.CASCADE, default=1)
    rating = models.DecimalField(default=0, max_digits=2, decimal_places=1)
    amount = models.IntegerField(default=0)
    task_description = models.TextField(max_length=1000, default=None)
    task_link = models.URLField(blank=True)
    latest_submission_time = models.DateTimeField(blank=True, null=True)
    isCompleted = models.BooleanField(default=False)
    deadline = models.DateTimeField(blank=True, null=True)
    task_attachments=models.FileField(default='Tasks To Do', upload_to='tasks_docs', validators=[validate_file_extension])


    def __str__(self):
        return self.task_name

And I am looking for a way to access tasks based on project. I can select a specific project and view its tasks

Mihail B
@mihailb1_gitlab
@jameskomo try this:
project = Project.objects.get(id=123).prefetch_related('task_set')
project.task_set.all()
you can also specify related_name for project property in Task

Is there anybody who can provide me some good resources for implement social authentication in Django-rest api?
Thanks :)

@elcolie
Supposed you have new feature that need geoDjango which is rely on postgist
Will you add extension to existing database and work with it or split it out to be new microservice over REST API?

Hi, I have a quick question.

Say I have models called "Post" and "Reaction" and I have made a Post, saved it and now I want to react on it with a Reaction.
Now, when I visit my feed where a list of Posts is, I want to show my reaction if I had one.

Which means:
{% if post.my_reaction %}{{ post.my_reaction.contents }}{% endif %}
Now, obviously I want to load more than just one Post; posts which don't have my reactions on it.

I know that I used to solve this with SQL in PHP with
SELECT * FROM Post 
LEFT JOIN Reaction ON Reaction.Post = Post.id
How do I do this in Django ORM ??
