Django logs not going to the expected log files
I have this LOGGING settings for my Django app. What I was expecting is that the views logs would go into their own separate folder when I have three different loggers in my views file.

How can we set a model is as default=0 or defoult=null in django
Two month back I had created two models and it was working well, and now these models have lot of query which is filled by users. It is clear that both models are independent to each other. My previous models.py class State(models.Model): state_name = models.CharField(max_length=300, blank=False) state_code = models.CharField(max_length=100, blank=False,unique=True) @classmethod def get_all_states(self): return State.objects.all() def __str__(self): return self.state_name class College(models.Model): college_name = models.CharField(max_length=300, blank=False) college_code = models.CharField(max_length=100, blank=False,unique=True) university_name = models.CharField(max_length=300, blank=True) def __str__(self): return self.college_name Today I want to design College model according to state wise. If users have selected some state than related college list will come. For this condition I have created below models.py class State(models.Model): state_name = models.CharField(max_length=300, blank=False) state_code = models.CharField(max_length=100, blank=False,unique=True) @classmethod def get_all_states(self): return State.objects.all() def __str__(self): return self.state_name class College(models.Model): college_name = models.CharField(max_length=300, blank=False) college_code = models.CharField(max_length=100, blank=False,unique=True) university_name = models.CharField(max_length=300, blank=True) state_id = models.ForeignKey(State, on_delete=models.CASCADE) @classmethod def get_all_colleges(self): return self.College.objects.all() def __str__(self): return self.college_name In code you can see state_id (in College models) is a foreign key. When I did migration then It's showing the error You are trying to add a non-nullable field 'state_id' without a default; we can't do that (the database needs something to populate existing rows). … -
Serialize Nested Django models with Many to Many fields
I am trying to serialize a nested django model which is structured as below: class Ingredients(models.Model): ingredient=models.CharField(max_length=264) def __str__(self): return self.ingredient class Step(models.Model): Steps=models.CharField(max_length=264) Ingredient=models.ManyToManyField(Ingredients) def __str__(self): return self.Steps class Recipe(models.Model): user=models.ForeignKey(Users,on_delete=models.CASCADE) recipie_name=models.CharField(max_length=2640) Steps=models.ManyToManyField(Step) def __str__(self): return self.recipie_name I have a main Recipe model which consists of a "number of Steps" and the Steps have "different ingredients" to them. All linked using Many to Many field relation. So far, I have been able to serialize using the below code class IngredientSerializer(serializers.ModelSerializer): class Meta: model=Ingredients fields='__all__' class StepSerializer(serializers.ModelSerializer): ingredient=IngredientSerializer(many=True,read_only=True) class Meta: model=Step fields='__all__' class recipe_serialized(serializers.ModelSerializer): Step=StepSerializer(many=True,read_only=True) Steps = serializers.StringRelatedField(many=True) depth = 2 class Meta: model = Recipe fields = '__all__' Which gives me an output like: { "id": 1, "Steps": [ "Add two bananas together", "Then mix them with apples" ], "recipie_name": "strudel", "user": 1 }, My problem is, I am having a hard time trying to "expand" the Steps as well. As the Steps have ingredients linked to them using a Many to Many relations. So the ideal serializer will have the Step portion further broken down too. Would appreciate any guidance in this regard Thank you -

Django channels creating two instances instead of one
I am using Django channels for real-time app purposes, more specifically to make real-time comments. And then I will explain my situation ... When someone sends a comment, they are supposed to create one and only one object in the database. The problem here is that when two or more users are connected to the same layer, the database creates two objects instead of just one. I have already reviewed and revised my code and I cannot find where I messed up. I hope I was able to explain my problem well so that you can help me!

Jquery returns an error where it cannot find the property of an objects (Django)
When I changed the import method I got an error on a live search. This is the JQUERY code I'm using. The error I'm gettin is the blogpost['title'] is empty. I've read that it might be due to the name blogpost being the overall container, so it's not actually a single blogpost but all the blogpost, but I don't know how to fix this.

eb deploy not able to resolve django application dependencies in requirements.txt
Here is the summary and order of events that happen when I deploy my code on AWS using eb deploy. The ec2 instance is unable to resolve the dependencies for the package "flake-logging-format 0.6.0" and the deployment fails with the error log shown below. I deploy after removing the dependency "flake-logging-format 0.6.0" from requirements.txt and it gets deployed successfully and the server starts running. I deploy again after re-adding the dependency "flake-logging-format 0.6.0" and this time it also gets deployed successfully and the server starts running. My question is: Why does the deployment fail in the first step, and why does it work after executing steps 2 and step 3, overall there is no difference in requirements.txt at step 1 and step 3.

Form not being saved in Database Django
I have created a form for a Post. The form loads and when I enter all the value and try to submit the form, it gets refreshed but the database is not updated. Here is my Post Model: class Post(models.Model): no_people = models.IntegerField() no_days = models.IntegerField() tour_date = models.CharField(max_length=200, blank=True) Gender_types = ( ('M', 'Male'), ('F', 'Female'), ('O', 'Others'), ) Gender_prefer = models.CharField(max_length=1, choices=Gender_types) location = models.CharField(max_length=200, blank=True) pic_location = models.ImageField(blank=True, upload_to="posts/") updated = models.DateTimeField(auto_now=True) created = models.DateTimeField(auto_now_add=True) detail = models.TextField() liked = models.ManyToManyField(Yatru, blank=True, related_name= 'likes') author = models.ForeignKey(Yatru, on_delete=models.CASCADE, related_name = 'posts',null=True) def __str__(self): return str(self.location) def no_likes(self): return self.liked.all().count() class Meta: ordering = ('-created',) def save(self, *args, **kwargs): self.location = self.location.upper() return super(Post, self).save(*args, **kwargs) LIKE_CHOICES = ( ('Like', 'Like'), ('Unlike', 'Unlike'), ) Here is the form: from django import forms from .models import Post class PostModelForm(forms.ModelForm): class Meta: model = Post fields = ('no_people','no_days','tour_date', 'Gender_prefer','location','detail') Here is the views: def post_add(request): user = request.user profile = Yatru.objects.get(user=user) form = PostModelForm(request.POST or None, request.FILES or None, instance=profile) if request.method == 'POST': if form.is_valid(): newpost=form.save(commit=False) newpost.user=request.user newpost.save() return render(request, 'posts/my_post.html',{'form': form}) This is the HTML file: <form method="POST"> {% csrf_token %} {{form.as_p}} <button type='submit'>Submit </button> </form> -
Запуск Django приложения на Heroku
Не получается выложить Django приложение на Heroku. Пользовался этими инструкциями https://python-scripts.com/django-simple-site-heroku но приложение не отображается. Кто может скать что в них не так?
