Profile matching query does not exist
I am following a tutorial on building a social media app using django. I have this bug that has kept me stuck for days despite doing exactly as the tutorial goes. Whenever i try to open the settings page of my profile, I get a doesNotExist error. the error seems to be coming from here " user_profile = Profile.objects.get(user=request.user) " This the views for my settings page @login_required(login_url='signin') def settings(request): # Check if logged in user has profile, if not redirect to create profile user_profile = Profile.objects.get(user=request.user) return render(request, 'settings.html', {'user_profile': user_profile}) Sometimes I get an error about the profile_img not being found. Although i couldn't get it to repeat itself at the time of asking for help here. But when I commented out the profile_img line in my modles.py, the error changed back to 'profile not matching query' This my models.py class Profile(models.Model): objects = models.Manager() user = models.ForeignKey(User, on_delete=models.CASCADE) id_user = models.IntegerField() bio = models.TextField(blank=True) location = models.CharField(max_length=150, blank=True) profile_img = models.ImageField(upload_to='profile_images', default='blank_profile_image.jpeg') However, removing the link to to my modles.py seems to make the settings page accessible. @login_required(login_url='signin') def settings(request): # Check if logged in user has profile, if not redirect to create profile #user_profile = Profile.objects.get(user=request.user) … -

I can only seem to get the initial Django landing page, no matter what I try. I feel like I understand the way it should work but there is obviously something wrong. I have tried the polls tutorial and several others on youtube and I am constantly having the same problem where the urls.py doesn't seem to include the things I believe to be in there. Any help would be greatly appreciated. mysite/mysite/urls.py# from django.contrib import admin from django.urls import include, path urlpatterns = [ path("", include('polls.urls')), path("admin/", admin.site.urls), ] mysite/polls/urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='index'), ] mysite/polls/views.py from django.shortcuts import render from django.http import HttpResponse Create your views here. def index(request): return HttpResponse("Hello, world!") -
Serialize several models in Django
I am looking to optimize the serialization of multiple models. Currently, I am able to serialize the models through the use of SerializerMethodField and providing the needed fields. I would like to use directly the serializer SiteSchoolSerializer to fetch in advance the results using queryset.select_related to reduce the time of the queries. I have the models: site.py: class SchoolDistance(models.Model): school_id = models.ForeignKey(School, on_delete=models.SET_NULL, db_column="school_id", null=True) school_distance = models.DecimalField(max_digits=16, decimal_places=4, blank=False, null=False) class Site(models.Model): date_created = models.DateTimeField(auto_now=False, blank=True, null=True) address = models.CharField(max_length=255, null=True, blank=True) nearest_school = models.ForeignKey(SchoolDistance, on_delete=models.SET_NULL, db_column="nearest_school", blank=True, null=True) ------------------ location_asset.py: class Location(models.Model): name = models.CharField(null=True, blank=True, max_length=255) location_type = models.CharField(null=True, blank=True, max_length=255) class Meta: unique_together = [['name','location_type']] ordering = ("id", ) class School(Location): description = models.CharField(null=True, blank=True, max_length=255) keywords = models.CharField(null=True, blank=True, max_length=255) class Meta: ordering = ("id", ) With the following serializers: distance.py class SiteSchoolSerializer(serializers.ModelSerializer): class Meta: #school = SchoolSerializer() model = SchoolDistance #fields = ('school_id', 'school_distance','school) why failing? fields = ('school_id', 'school_distance') ------------------ location_types.py: class SchoolSerializer(serializers.ModelSerializer): class Meta: model = School fields = ( "id", "name" ) -------- get.py: class SiteGetSerializer(serializers.ModelSerializer): # nearest_school = serializers.SerializerMethodField() nearest_school = SiteSchoolSerializer(required=False) class Meta: model = Site fields = ( "id", "address", "nearest_school", #Should include name besides id and distance … -
CS50W - Network - Like Button working but Like count is not updating
I am currently working on Project4 from CS50W. The task is to write a social media like site where users can post, follow and like. I have implemented a like button to every post (which is wokring fine) unfortunately I have to refresh the page for the like to show. I whould rather want the like to update directly after clicking the like button.

Django URLs returning 404 page not found error after adding a trailing slash
I am working on a Django project and I am having some trouble with the URLs. I recently added a trailing slash to the URLs in my "urls.py" file for the app(I have only one), and now i'm getting a "Page not found (404)" error whenever I try to access anypage (only "http://127.0.0.1:8000/HomeS" works). I want to access studio page(or any) without the "HomeS" . It works if I enter the url manually.(for example : http://127.0.0.1:8000/studio ) I get a "Page not found (404)" error. Here's the error message that I see:Error page I have checked my code and I believe that my URLs are correctly defined. Here relevant part of my "url.py" file : url.py I have tried restarting the server, clearing the cache, and even creating a new virtual environment, but the error persists. I would appreciate any help in resolving this issue. Thank you.
