Ordereddict has no attribute caled "..."
I'm trying to upload an object in json format using api_view(), in django-rest-framework. serializers : class ProductSerializer(serializers.ModelSerializer): class Meta: model = Product fields = ['id', 'title', 'description', 'unit_price', 'price_with_tax', 'slug', 'inventory', 'collection'] price_with_tax = serializers.SerializerMethodField(method_name='calculate_tax') def calculate_tax(self, product: Product) : return product.unit_price * Decimal(1.1) views: @api_view(['GET', 'POST']) def product_list(request): if request.method == 'GET': queryset = Product.objects.select_related('collection').all() serializer = ProductSerializer(queryset, many=True, context={'request':request}) return Response(serializer.data) elif request.method == 'POST': serializer = ProductSerializer(data=request.data) serializer.is_valid(raise_exception=True) serializer.validated_data return Response(serializer.data, status=status.HTTP_201_CREATED) Collection and Products models: class Collection(models.Model): title = models.CharField(max_length=255) featured_product = models.ForeignKey( 'Product', on_delete=models.SET_NULL, null=True, related_name='+', blank=True) def __str__(self) -> str: return self.title class Meta: ordering = ['title'] class Product(models.Model): title = models.CharField(max_length=255) slug = models.SlugField() description = models.TextField(null=True, blank=True) unit_price = models.DecimalField( max_digits=6, decimal_places=2, validators=[MinValueValidator(1)]) inventory = models.IntegerField(validators=[MinValueValidator(0)]) last_update = models.DateTimeField(auto_now=True) collection = models.ForeignKey(Collection, on_delete=models.PROTECT) promotions = models.ManyToManyField(Promotion, blank=True) this is the object I'm trying to upload and create: { "title": "a", "slug": "a", "unit_price": 1, "collection": 1, "inventory": 1, } I tried to get rid of the calculate_tax part, because the error raised in that part but nothing really crossed my mind besides that -
How should mysql.connector be shared correctly with threads in Django applications?
This concerns a potential solution to my earlier question in which I was getting commands out of sync; you can't run this command now after wrapping mysql cursors in __enter__ and __exit__. I have read elsewhere that Django does not spawn new threads to handle multiple requests, but rather multiple Django processes would normally be spawned in order to achieve parallelism. Despite this advice, I began printing Thread.ident and Thread.native_id and noticed that they were changing. Based on this, I speculatively wrote something like: def db_connect (): t = threading.current_thread() if not hasattr (t, 'db_connection'): print (f"New MyDBConnectionClass for {t.ident}~{t.native_id}") t.db_connection = MyDBConnectionClass () return t.db_connection.get_cursor () # This object has a __exit__ which closes the cursor along with class MyDBConnectionClass (): def __del__(self): t = threading.current_thread() print (f"MyDBConnectionClass deleted for {t.ident}~{t.native_id}") the view handlers' usage of the cursors is unchanged: with db_connect() as db: results = db.all (query, args) So far this seems to have fixed the commands out of sync error (and the exit code 245 crash mentioned in the original question). MyDBConnectionClass.__delete__ is not being called, but various instances are created for a few different ident values. My current hypothesis is that there is some sort of … -

How can I tell Django not to load a certain column from the DB
I’m beginning to learn more about improving my app’s performance, and I know while querying I can tell Django to only load the columns I want from the db by using the only method like the code below: books = Books.objects.only("author", "title") What if I want Django to retrieve books but not retrieve the narration column. Please help. Thank you in advance I have tried to include all columns except the narration column and that’s too stressful. I believe there should be a way to exclude only one column. -

The post counter not working in my Django project
I am doing a project for my Django course and I hit a wall that I cannot overcome. I tried to find the answer here, but the seems similar to what I already have put in place. So, my project is a forum and posts can be made inside a category. The index page shows the different categories and the amount of posts inside each category. However, no matter how many posts are created the counter does not change. This is the model for the category and for the post class Category(models.Model): title = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) content = models.TextField() featured_image = CloudinaryField('image', default='placeholder') excerpt = models.TextField(blank=True) created_on = models.DateTimeField(auto_now_add=True) posts = models.ManyToManyField( 'Post', related_name='categories', blank=True) class Meta: ordering = ['created_on'] def __str__(self): return self.title def number_of_posts(self): return self.posts.count() class Post(models.Model): title = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) author = models.ForeignKey( User, on_delete=models.CASCADE, related_name="posts_list") content = models.TextField() featured_image = CloudinaryField('image', default='placeholder') excerpt = models.TextField(blank=True) created_on = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) likes = models.ManyToManyField(User, related_name='post_likes', blank=True) favourite = models.ManyToManyField( User, related_name='favourite', blank=True) category = models.ForeignKey( Category, on_delete=models.CASCADE, related_name='category') class Meta: ordering = ['created_on'] def __str__(self): return self.title def number_of_likes(self): return self.likes.count() def number_of_comments(self): return self.comments.count() this is … -

Customized Parsing Text in Django Framework
I'm developing an application using Django to provide an issue content from JIRA, issue tracking system developed by Atlassian. My question is how can I parse an inner content of a field of the issue efficiently saving my time? Now I pull all the content of an issue using the below code: issue = jira.issue('issue_no') print(issue.raw['fields']['issuetype']) print(issue.fields.status) print(issue.fields.description) When I print the issue.fields.description, it shows all text in that description field. BTW, my goal is to provide a description from an selected issue and want to parse the description field to pick strings in a specified pattern starting with 'SRC_' and summary written by users. For example, I want to remove the below strings and need to select a part of description after {color} tag. {panel:bgColor=#deebff} h1. *Summary* {panel} h1. {color:#0747a6}*Short Description*{color} The string after parsing can be vary but it is an example: Created tables ... # Source_file_name_1 # Source_file_name_2 " How can I make the customized text that will show to users? -
Django/Python Web Scraping - the targeted tag isn't being found to pull the information I need
I am working on a Django web application for sports cards. Each card has their own page that displays the card name at the top, and underneath it should display the current lowest price of that card.

How to partially match URLs when searching with Django Full Text Search
I have a Django model representing a website, and I use the Postgres Full Text Search to search the Website objects. However, if you search for only part of a website's url, it doesn't return matching Websites. e.g. if a Website has a url of "https://www.example.com/foo/" and you search for "example" or "foo", then that Website isn't returned in results. I could create a new field, that's populated on save, which contains the url, but with parts separated by spaces. e.g. "www example com foo". And then index that. But then this wouldn't work if the user searched for "example.com". Is there some way I can use Full Text Search to search for partial matches on the url field, as well as still searching title and description? My model: from django.contrib.postgres.indexes import GinIndex from django.contrib.postgres.search import SearchVectorField from django.db import models class Website(models.Model): title = models.CharField(blank=True, null=False, max_length=255) url = models.URLField(blank=False, null=False, max_length=255) description = models.CharField(blank=True, null=False, max_length=1000) search_document = SearchVectorField(null=True) class Meta: indexes = [GinIndex(fields=["search_document"])] def index_components(self): return ( (self.title, "A"), (self.url, "B"), (self.description, "C"), ) Not sure this is relevant, but for completeness, there's a post save signal that updates the index, something like this from here: from … -

Problem starting Django container in production (Whitenoise?)
I have suddenly started having trouble starting up my website in production after I moved to a new VPS hosting service. I was using Vultr and moved to Digitalocean because response time was way faster when using Ansible (for the same machine configuration). In both cases I was using Ubuntu 23.10 as a host. I also tried to do "compose up" with production.yml in my dev machine and the error is the same, so I guess it has nothing to do with the change of hosting service.

Make inner joins by using Q objects in Django
I'm customizing a model's Admin change list page in my project. This model contains a Many to Many field and I want to allow multi-selection filtering. I've used the Django Admin Multi Select Filter package to do this but I noticed that the default behaviour in Django's __in lookup is to be inclusive and not exclusive. Imagine I have an object A associated with M2M objects 1 and 2 and object B associated with M2M objects 2 and 3. If I make the following query Model.objects.filter(m2m_model__in=[1,2]) I will have both objects A and B being retrieved, since the search will use the following condition: Index Cond: (models_model_m2mfield.model_id = ANY ('{1,2}'::bigint[])) I was able to customize the behaviour of the search by doing the following: for choice in choices: queryset = queryset.filter(**{self.lookup_kwarg: choice}) This generates inner joins and returns the value I'm waiting for (only objects matching every option). INNER JOIN "models_model_m2mfield" ON ("models_m2mmodel"."id" = "models_model_m2mfield"."m2mfield_id") INNER JOIN "models_model_m2mfield" T4 ON ("models_m2mmodel"."id" = T4."m2mfield_id") WHERE ("models_model_m2mfield"."model_id" = 4 AND T4."model_id" = 5) I've tried using Q objects to get the same result, but I couldn't make it work. Is it possible to achieve the same behaviour using the Q class? -

"commands out of sync; you can't run this command now" on first use of cursor
I am using MySQL in Django (Python). The draft version of this code worked and was stable, but it created cursors without closing them, and I just rewrote it to manage the cursor with enter/exit. Now it is unstable. class Cursor: def __init__ (self, db): self.db = db self.cursor = db.DB_connection.cursor () def __enter__ (self): return self def __exit__ (self, ex_type, ex_value, ex_traceback): if ex_value is not None: # log stuff self.cursor.close () self.cursor = None def __del__ (self): if self.cursor is not None: # log stuff self.cursor.close () def one (self, query, args): self.cursor.execute (query, args) return self.cursor.fetchone () class DB: def __init__ (self, my_stuff): self.DB_connection = connect (...) def get (self): return Cursor (self) and in the application: with DB_connection.get() as db: result = db.one ("SELECT ...", ...) Sometimes this works as before, but sometimes randomly it will fail calling db.one() _mysql_connector.MySQLInterfaceError: Commands out of sync; you can't run this command now this exception is seen in Cursor's __exit__ Googling this error tells me that this means an earlier SELECT on that cursor still has un-fetched results.

Handling formsets in Django
In my django project, I want to use formsets, but I have a problem with handling the POST requests. I defined my formset this way: strategy_settings = formset_factory(StrategySettings) strategy_formset = strategy_settings(request.POST) Then I tried to loop through all of the forms in a formset if the forms are valid: if strategy_formset.is_valid(): for form in strategy_formset: data = form.cleaned_data["data"] But the thing is, although I fill the forms with proper data, the forms are not valid, I checked this by printing statements in the console. No error appears, when I submit the forms, formset just disappears from a page. Here is my full view: def input_view(request): if request.method =="POST": simulation_form = SimulationSettings(request.POST) # Regular form strategy_settings = formset_factory(StrategySettings) # Formset strategy_formset = strategy_settings(request.POST) # Formset if simulation_form.is_valid() and strategy_formset.is_valid(): print("valid") initial_amount = simulation_form.cleaned_data['initial_amount'] number_of_simulations = simulation_form.cleaned_data['number_of_simulations'] number_of_trades = simulation_form.cleaned_data['number_of_trades'] values_from_all_forms = [] for form in strategy_formset: accuracy = form.cleaned_data['accuracy']/100 take_profit = form.cleaned_data['take_profit'] / 100 stop_loss = form.cleaned_data['stop_loss'] / 100 max_dd_list = [] for simulation in range(0, number_of_simulations): trades = (["W"] * int(number_of_trades*accuracy)) + (["L"] * int(number_of_trades * (1-accuracy))) random.shuffle(trades) current_amount = initial_amount current_amount_list = [] profit_list = [] for trade in trades: if trade == "W": current_amount = current_amount + current_amount*take_profit … -
Issue with Database Queries in Authenticated Django API Calls Despite JWT Verification
Each time an authorized API call is made using a bearer token (specifically a simple JWT), a database query is executed to retrieve user details, even though JWT Authentication is supposed to eliminate the need for database validation. Could someone help me understand the reason behind these database queries and suggest a solution to avoid them while still ensuring proper authentication through JWT? Your insights would be greatly appreciated! When making a request to a Django API with a JWT bearer token, an extra database call is initiated to retrieve user details associated with the user ID specified in the token payload. SELECT "auth_user"."id", "auth_user"."password", "auth_user"."last_login", "auth_user"."is_superuser", "auth_user"."username", "auth_user"."first_name", "auth_user"."last_name", "auth_user"."email", "auth_user"."is_staff", "auth_user"."is_active", "auth_user"."date_joined" FROM "auth_user" WHERE "auth_user"."id" = 2 LIMIT 21; args=(2,); alias=default .
