Django - Building a comment system, should I use formsets?
I'm building the comment section of a Q&A page, where users can either leave full replies or just comments (identical to Stack Overflow's system). There is a 'Add Comment' attached to every entry on the page. I read up on formsets and from my understanding so far, formsets don't seem to be the optimal solution for this problem. I believe the best way of building this system is to add a comment_form in each entry. {% for a in answers %} {{ a }} <form method="post"> {{ comment_form }} </form> {% endfor %} Should I use formsets? Or use the method I wrote above? -
moved app to another app dropped tables can't migrate in Django
As the title says I moved some models from an existing app into another app. Then I deleted the old app ran DROP TABLE for all old app tables prepended with oldapp_model... and ran makemigrations on an existing database. It says there are no migrations to apply and when hitting the newer migrations it says there is: no relation newapp_model How can I get it to pick this up and create the new model in the new app? -
creating expiry in django cause received a naive datetime
In my Django app, I have in my model set for expiry this way: expiry = models.DateTimeField(default=datetime.now()+timedelta(days=5)) And when i did makemigration and migrate Applying ../lib/python3.6/site-packages/django/db/models/fields/__init__.py:1451: RuntimeWarning: DateTimeField AuthEmployeeSessionToken.expiry received a naive datetime (2017-12-09 00:03:20.106930) while time zone support is active.

RuntimeWarning) OK what would be the right way to solve this problem ? I saw like timezone.now(), is that right since Im using DateTime field ? Would like a definite way of setting expiry in the model automatically when created. -

show category and sub-categories in hierarchy
I am using django-mptt for category model. I want to show a list of categories and sub-categories as in the screenshot. The way I could show is all the list without any structure like below BEDROOM ITEMS ALMIRAH 2 PIECE ALMIRAH 3 PIECE ALMIRAH BED DOUBLE SIZE LOW BED QUEEN SIZE LOW BED This way its hard to know which one is parent category and which one is child category and grand-child category etc. I could either show the above way or show only the parent category using Category.objects.root_nodes() here is my model, views and template class Category(MPTTModel): name = models.CharField(max_length=100, blank=True, null=True) image = models.ImageField(null=True, blank=True, upload_to=upload_furniture_image_path) slug = models.SlugField(max_length=200, unique=True) parent = TreeForeignKey('self', null=True, blank=True, related_name='children', db_index=True) def furniture(request, slug): instance = get_object_or_404(Furniture, slug = slug) cart_obj, new_obj = Cart.objects.new_or_get(request) categories = Category.objects.all() context = { 'furniture': instance, 'cart': cart_obj, 'categories': categories } return render(request, 'furnitures/furniture.html', context) <div class="panel-body"> <ul class="nav nav-pills nav-stacked category-menu"> {% for category in categories %} <li>{{category.name}}</li> {% endfor %} </ul> </div> So my question is how could I separate Parent Category and child category so I can show as in screenshot? -
How do I fix this error in Python Django involving request.user.is_authenticated() and bool object not callable?

how to pass extra field for mutation? django-graphene
I am learning to use django-graphene for graphql purpose. I learned through a few tutorials and got some ideas on how to work and made them work. I got mutation to work for create and update BUT that's only if using all available fields that already exists in models. I am wondering what IF I am passing in fields that's not included in a model. For example, if there is a token to be passed for authentication purpose or whichever fields need to be passed. I have these codes class ProductType(DjangoObjectType): class Meta: model = Product filter_fields = {'description': ['icontains']} interfaces = (graphene.relay.Node,) class ProductInput(graphene.InputObjectType): token = graphene.String() # this would be some token to check for authentication title = graphene.String() barcode = graphene.String(required=True) class CreateProduct(graphene.Mutation): class Arguments: product_input = ProductInput() # form_errors = graphene.String() product = graphene.Field(ProductType) def mutate(self, info, product_input=None): if product_input.get('token'): # do something here pass product = Product.objects.create(barcode=product_input.barcode, title=product_input.title) return CreateProduct(product=product) class ProductMutation(graphene.ObjectType): create_product = CreateProduct.Field() I have my query for graphql as mutation ProductMutation { createProduct(productInput:{token:"sometoken", title:"hello", barcode:"codes"}){ product{ id, title, barcode } } } which of course doesn't work that's why I am wondering if anyone can give me a hand.

django 3.6.3 runs in Windows development but hangs in Linux production
python 3.3.6 django 1.11 I am lost, I am working on what I think is a fairly simple first django site. I am doing development on a windows machine. I deploy to a Linux machine. Both are running python 3.6.3. The local/windows version can be run with the built-in server. When I deploy the site to the production machine thought I get an unhelpful message: Web application could not be started An error occurred while starting the web application: it did not write a startup response in time. Please read this article for more information about this problem. Raw process output: (empty) I've done some googling about debugging in production but since my code is not actually throwing an exception nothing is caught and here I sit. I have put diagnostic print statements in my vires.py and apps.py files. They do not drop anything in either the access.log or error.log. I'm open to ideas here. Again, the app seems to work on the dev PC but gives the Web application could not be started error in Linux production. -

Filtering queryset by number of many-to-one relationships with a raw SQL query
I am creating a resources page, and I have the following models: class Tag(models.Model): title = models.CharField(max_length=50, blank=False, unique=True, error_messages={'unique':"THis tag already exists."}) class Link(models.Model): title = models.CharField(max_length=100, blank=False) tag = models.ForeignKey(Tag, on_delete=models.CASCADE, null=False, blank=False) Which have more fields but they are irrelevant to this matter. The problem with this resources page was that Tags with no Link establishing relationship with them were still appearing, and I wanted only for tags with at least one Link under them to appear. Now, I have managed to do this with this queryset filtering: tags = Tag.objects.all().filter(link__isnull=False).order_by("title").distinct() Which works alright in my views.py, and what I want is done already. Note that the "distinct" is necessary so that it doesn't return duplicate queries. I have had very little experience with MySQL and only have built very simple applications with it and PHP. I have now idea how it would function under SQLite, nor would I even know how to this with MySQL. Under my (very informal) logic, it would function something like this (please, forgive my killing the language): SELECT * FROM Tags WHERE NUMBER_OF_RELATIONSHIPS IS GREATER THAN 1 My question is actually how could this be achieved through a Raw SQL query, … -
Filtering queryset by number of many to one relationships
I'm creating a resources page, and there are a few Tags with foreign key relationships to Links. These are my models (having left out irrelevant, to this issue, parts of the code): class Tag(models.Model): title = models.CharField(max_length=50, blank=False, unique=True, error_messages={'unique':"Esta tag já existe."}) class Link(models.Model): title = models.CharField(max_length=100, blank=False) url = models.URLField(blank=False) language = models.CharField(max_length=10, blank=False) tag = models.ForeignKey(Tag, on_delete=models.CASCADE, null=False, blank=False) There is a page with several links, which appear under the tags. The problem is, if the tags have no links related to them, they will still appear. I believe the solution for this is to leave out of the queryset the tags with no relationships. I believe there is one way through this, which is the following logic: SELECT * FROM Tag WHERE NUMBER OF RELATIONSHIPS IS GREATER THAN OR EQUAL TO 1 And this would be done through a Raw SQL query, I believe, but I don't know that much SQL. Maybe that is also possible through filtering? How could I proceed to do this? -

Calculate a form field in Django based on another field
I have this scenario: a customer wants to know the equivalent of a sum in his local currency. He fills a form (ModelForm) where he indicates the amount and the country and I need to calculate the equivalent amount in local currency. I created : 1- A model with the countries and their currency exchanges 2- A model with the initial amount in dollars, the country of exchange(ForeignKey from the first model) and the equivalent amount in local currency 3- A form (Modelform) from the second model 4- A function that takes the initial amount and the country and calculates the equivalent amount in local currency My question is: how can I update the local amount field of the form and save it in the database based on the first 2 fields of the form? I tried this: if form.is_valid(): conversion = form.save(commit=False) conversion.converted_amount=calculate(conversion.initial_amount,conversion.country) conversion.save() but I got this error: invalid literal for int() with base 10: 'India' What am I missing?

Django search or filter depending on the url
I have a site with Django which contains multiple blogs. I am trying to make filters by categories from the menu depending on the url: If I'm in the home - get all the entries of a category that belong to any blog. url example: www.site.com/category_path/ If I'm in a blog - get all the entries of a category that belong to the current blog. url example: www.site.com/blog_slug/category_path/ I can solve this by changing the urls I call in the menu. Example: <a href="{% url 'blogosphere:categories:detail' category_path='music' %}">Music</a> Example: <a href="{% url 'blogosphere:blogs:categories:detail' blog_slug=blog.slug category_path='music' %}">Music</a> But I would like to see if there is a more elegant way to do it. Thank! PD: I want to solve this for the search also. -
Using Django in a multithreading code
I am running a python script using django ORM to handle calls to the database. I have the following code: with ThreadPoolExecutor(max_workers=2) as executor: executor.submit(process, 2) executor.submit(process, 1) @transaction.atomic def process(counter) MyModel.objects.filter(user_id=counter).delete() users = <create User object) MyModel.objects.bulk_create(users) I am using django default behavior which sets the auto-commit to True. When I debug the code, it looks that django uses the same connection among the application, and therefore, the last process that will exit process method, will commit all the transactions that are using the connection. How can I prevent it to happen? I would like django to close (and commit) the connection at the end of each method so each thread could be handled separately.
