Here is my views.py file. I input the required fields through form like this:
from django.shortcuts import render, redirect
from .models import nekor_Table
from .forms import user_form
def home(request):
user_form_obj = user_form()
if request.method == "POST":
form = user_form(request.POST)
if form.is_valid():
form.save()
else:
form = user_form_obj()
context = {'user_form_obj': user_form_obj}
return render(request, 'polls/home.html', context )
def nav(request):
return render(request, 'navbar.html')
def display(request, pk):
display_table_obj = nekor_Table.objects.get(id=pk)
context = {'display_table_obj': display_table_obj}
return render(request, 'polls/display_page.html', context)
i have two tables and when i try to get individual instance with id=pk, and running http://127.0.0.1:8000/display/1/ in my browser it gives me: nekor_Table matching query does not exist, error. what am i missing here? this was working just fine in my previous project but doesnt work in this one.
here is my urls.py:
from django.urls import path
from . import views
urlpatterns = [
path('index/', views.home, name='home'),
path('navbar/', views.nav, name='navbar'),
path('display/<int:pk>/', views.display, name='display')
]
and here is my models.py
from django.db import models
from django.contrib.auth.models import User
class nekor_Table(models.Model):
title = models.CharField(max_length=200, null=True, blank=False)
place = models.CharField(max_length=200, null=True, blank=False)

I'm using the Django and React to create YouTube clone.
And when the user is creating second video, it giving the bad request error:
<QueryDict: {'title': ['Edit Test56'], 'description': ['is It working1643'], 'user': ['3'], 'image': [<TemporaryUploadedFile: slackphot.png (image/png)>], 'video': [<TemporaryUploadedFile: video-for-fatube.mp4 (video/mp4)>]}>

When I tried to make post request in postman, it gave me
views.py Views of the api.

If you want to look at the whole project, here is github: https://github.com/PHILLyaHI/diplom-work
You are using One2One Field, that's why it's causing an error, use foreign key in User column

I have a foreign key on my comment model, I tested this on django admin and it works fine, but with my comment form, the foreign key isn't populating, i just get "null value in column "user_id" violates not-null constraint", I dont know what im doing wrong
class Comment(models.Model):
comment = models.CharField(max_length=250)
user = models.ForeignKey(UserAccount, on_delete=models.CASCADE)

from accounts.models import Comment

class UserCreateSerializer(UserCreateSerializer):
class Meta(UserCreateSerializer.Meta):

I am reffering my foreign key user as a field, i'm not sure if that is correct.

You need to add user_id field for writing in the serializer.
class CommentSerializer(ModelSerializer):
class Meta:

After I added user and date_added in the Photo models, when I add post from admin its throws me an error saying: str returned non-string (type Category), when I click on the addpost link in the home template its throw another error: 'tuple' object has no attribute 'name'. how can I solve that ?
the models.py:
from django.db import models
from cloudinary.models import CloudinaryField
from django.contrib.auth.models import User
# Create your models here.
class Category(models.Model):
name = models.CharField(max_length=100, null=False, blank=False)
def __str__(self):
return self.name
class Photo(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True,
blank=True)
image = CloudinaryField('image')
description = models.TextField(null=True)
date_added = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.category
the view.py file:
def home(request):
category = request.GET.get('category')
if category == None:
photos = Photo.objects.all()
else:
photos = Photo.objects.filter(category__name=category)
categories = Category.objects.all()
context = {'categories': categories, 'photos': photos}
return render(request, 'home.html', {'categories': categories, 'photos': photos} )
def viewPhoto(request, pk):
photo = Photo.objects.get(id=pk)
return render(request, 'photo.html', {'phpto': photo})
class PostCreativeView(LoginRequiredMixin, CreateView):
model = Photo, Category
fields = ['description', 'image', 'category', 'name']
template_name = 'post_create.html'
def form_valid(self, form):
form.instance.user = self.request.user
return super (PostCreativeView, self).form_valid(form)
Well it has to do with your category name and model you added into post create view.py and so you
have do something like this:
views.py
class PostCreativeView(LoginRequiredMixin, CreateView):
model = Photo
fields = ['description', 'image', 'category']
template_name = 'post_create.html'
def form_valid(self, form):
form.instance.user = self.request.user
return super (PostCreativeView, self).form_valid(form)
#.......
# Models.py
class Photo(models.Model):
#>>>...
def __str__(self):
return str(self.category)
You should return the str(…) of the category, so:
class Photo(models.Model):
# …
def __str__(self):
return str(self.category)

open and edit admin.py
and register your models by adding code below admin import
from .models import CustomUser,StudentDetail,AlumniDetail
admin.site.register(CustomUser)
admin.site.register(StudentDetail)
admin.site.register(AlumniDetail)

The SQLlite DB was corrupt due to too many migrations, it can happen. I deleted SQLlite and all my migrations, I retried migrate, makemigrate and sqlmigrate, it resolved the issue.
If you run into a similar issue in a dev environment please try the following
1. Delete all your migrations in the migrations folder
2. Delete db.sqlite3
3. Run python manage.py migrate
4. Run python manage.py makemigrations
5. Run python manage.py sqlmigrate appname 0001
This will fix this issue.
