How can I implement few checkboxes in a Django Form?
I was given a task to create a recipe website. A user can add a recipe. They have to choose a category (categories). One recipe can belong to one category or to several. I am inheriting my Form from ModelForm. Here's the code for it: class RecipeForm(ModelForm): class Meta: model = Recipe fields = ['title', 'description', 'ingredients', 'cooking_steps', 'time', 'calories', 'portions', 'image', 'categories'] widgets = { 'title' : TextInput(attrs={'class' : 'create_recipe_title', 'placeholder' : 'Enter a title...' }), 'description' : TextInput(attrs={'class' : 'create_recipe_description', 'placeholder' : 'Enter a short description...' }), 'ingredients' : Textarea(attrs={'class' : 'create_recipe_ingredients', 'placeholder' : 'Your ingredients...', 'disabled' : True }), 'time' : NumberInput(attrs={'class' : 'create_recipe_time', 'placeholder' : 'Cooking time...' }), 'calories' : NumberInput(attrs={'class' : 'create_recipe_calories', 'placeholder' : 'Calories...' }), 'portions' : NumberInput(attrs={'class' : 'create_recipe_portions', 'placeholder' : 'Portions...' }), 'image' : FileInput(attrs={'class' : 'create_recipe_image'}), 'cooking_steps' : Textarea(attrs={'class' : 'create_recipe_cooking_steps', 'placeholder' : 'Describe the cooking process...' }), 'categories' : SelectMultiple(choices=[(1, 'Food'), (2, 'Drinks'), (3, 'Hot'), (4, 'Cold'), (5, 'Breakfast'), (6, 'Lunch'), (7, 'Dinner'), (8, 'Выпечка и десерты'), (9, 'Soups'), (10, 'Salads'), (11, 'Pizza and pasta'), (12, 'Sauces'),(13, 'Portugal'), (14, 'Italy'), (15, 'France'), (16, 'Japan'), (17, 'Chine'), (18, 'Georgia'), (19, 'Armenia'), (20, 'Mexico'), (21, 'Africa'), (22, 'Dietary'), (23, 'Sugar free'), (24, … -
Type Error while populating a model in Django with UniqueConstraint
I'm trying to build up my first project in Django and I'm having some issues while creating an entry into my model Prevision (including sales forecasts), which has a uniqueConstraint to ensure that there is only one forecast between a Supplier (model "Representada") and a Customer (model "Cliente") for a give year (field "Ano").

drf_yasg: Not able to generate Swagger UI from YAML file
I am using the drf_yasg library in my Django REST Framework project to generate Swagger documentation. I have defined my API endpoints and schemas in a YAML file, but when I try to generate the Swagger UI, it is not rendering correctly.

How to code efficiently in a django project?
I am begineer in django, i am doing my first project in django. I am using mysql database with my project. Now while fetching data from the database and showing it in different sections of my projects need some logic, so i am using simple "for loops" , "if else statements" to do all this. I am also using boolean flags inside the database to execute different logic. I want to know, is this a correct approach to make a django project, or is there any startergy i should follow while adding new features or making new code ? Kindly help, I just want to know about the technique i should follow, as a begineer this question might be simple but it might be important for many as well.

How do I minify my HTML so that CSS and FontAwesome and Bootstrap names are reduced
I have a Django website that displays a table with data. It uses FontAwesome and Bootstrap for styling - which leads to some lengthy HTML (a standard page is 136k). Eg Some TDs contain an arrow using FA and a style to rotate it eg <i class="fa-solid fa-arrow-down fa-lg fa-rotate-by" style=--fa-rotate-angle:282deg></i> Is there a way to minify or some how reduce the name sizes? I have been reading about webpack and gulp minifiers but I cannot find anything that mentions the use of 3rd party assets like FA and BS and how one might reduce their name sizes. Also these seem somewhat targeted to client-side frameworks rather than server-side which mine is. -

How to reduce the amount of HTML style code
I have a Django website that displays data in a table, most of the data is highlighted with a calculated background color to make it quickly obvious to the user. Is there a way to reduce the amount of HTML I am outputting? Eg: <td style=background-color:#5eff00>19</td> Ideally I'd use CSS - but I would literally be creating a class for every hex color value. Is there a better way? I did consider using the html bgcolor attribute but this is not supported by HTML5. Is this a possibility? -
Django code freezes using Daphne on async database queries
I am running an async django application that is downloading some data. As I want the downloads to run asynchronously, I defined some async methods to run as coroutines. These methods sometimes have Django ORM queries, which I also run asynchronously (async for loop, sync_to_async or .aget(), for example). Since I'd like to display the download progress in clients browser in realtime, I installed django-channels together with daphne to setup websockets. However, If I run my code without daphne, everything works perfect. But as soon as I register daphne as app in settings.py (that runserver is actually running daphne serevr), the code stucks at a async database query. More details: settings.py: ASGI_APPLICATION = 'MultiClaw.asgi.application' INSTALLED_APPS = [ 'daphne', ... ] The view, that is mapped to a button which starts the download: @csrf_exempt def start_grab_thread(request): parser_name = request.POST['parser_name'] settings_model = Settings.objects.filter(user=request.user, parser_name=parser_name)[0] parser_module = importlib.import_module(f'parser.Parser.{parser_name}') parser_class = getattr(parser_module, parser_name) parser_instance: Core = parser_class(settings_model) asyncio.run(parser_instance.download_products()) if request.method == "POST": return redirect('start') the function, where the problem occures: async def download_products(self): print('downloading products') collected_product_urls = self.product_url_list print(f'{collected_product_urls=}') product_urls_from_db = set([ product.source_url async for product in Product.objects .filter(pk__in=collected_product_urls) ]) print(f'{product_urls_from_db=}') print(f'FINALLY GOT IT') return I tried many attempts, wrap the query into a … -

Django automatic conversion/casting when doing lookups

I did some research in the official documentation and couldn't find anything. from django.db import models class Document(models.Model): id = models.IntegerField(primary_key=True) name = models.CharField(max_length=100) # Query using an integer document1 = Document.objects.get(id=1) # Query using a string that can be converted to an integer document2 = Document.objects.get(id='1') # Both queries should yield the same result I check this pages in the official documentation: https://docs.djangoproject.com/en/5.0/ref/models/fields/#model-field-types https://docs.djangoproject.com/en/5.0/topics/db/queries/ https://docs.djangoproject.com/en/5.0/ref/models/lookups/ -

Django urlpatterns including / at the back
I'm a student learning Django. I have a question and I'd appreciate it if someone could help me. When I navigate to 127.0.0.1:8000/feeds/1, it correctly displays the feed with ID 1. However, I encounter an issue when I navigate to 127.0.0.1:8000/reviews/1, and I get the following error says page not found This problem can be resolved by adding a slash in the reviews/urls.py path section like this: "int:review_id/". My question is: why does the feeds URL work without the trailing slash in the urlpatterns, but for reviews I have to include the trailing slash to make it work? here is the main urls.py from django.contrib import admin from django.urls import path,include urlpatterns = [ path("admin/", admin.site.urls), path("feeds/", include('feeds.urls')), path("users/", include('users.urls')), path("reviews/",include('reviews.urls')) # path("boards/", include('boards.urls')) ] # feeds/urls.py from django.urls import path from . import views urlpatterns = [ path("", views.Feeds.as_view()), path("<int:feed_id>",views.FeedDetail.as_view()) ] # reviews/urls.py from django.urls import path from . import views urlpatterns = [ path("", views.Reviews.as_view()), path("<int:review_id>/", views.ReviewDetail.as_view()) ] -

Why doesn't DataDog show BEGIN queries?
I am using DataDog with a Django site running on gunicorn with a Postgresql database. We have atomic DB transactions enabled by default. Postgres and Python traces are both configured per the DataDog documentation. In DataDog we can see the Postgres spans for the transaction COMMIT queries, but the transaction BEGIN queries are missing. I am trying to debug some performance issues with our site and would like to see if the BEGIN queries are somehow at fault, but it's nearly impossible to confirm this when they aren't showing up in DataDog. How do I get the transaction BEGIN queries to show in DataDog? This is a screenshot of a trace from the /health endpoint, which executes zero SQL queries but is still wrapped in a DB transaction. You can see that most of the response time is a black hole where I cannot see what is happening. This trace was only 9ms, but sometimes this delay can take up to 10 seconds which is totally baffling. -
Is there an way to go around the "Field 'id' expected a number" when dealing with a queryset?
I am working on a learning platform. I want to be able to track user progress of the chapters completed. I cerated a new model and inserted it into the html using a form. However when I submit, I keep getting a TypeError with the specifics that "Field 'id' expected a number but got <QueryDict: {'csrfmiddlewaretoken': ['YMvOO6ZYGWVVfxfgoFLVEanZ9zK70CrqlRIx5Y2LOkbzH8Mx3UHPlQYczqLbq1Qt'], 'chapter': ['2'], 'completed': ['on'], 'student': ['1']}>" I tried converting all the variables I was using to identify the user, student and chapter to their primary keys but I got even more complicated error. If there is an easier way to track the progress or a tutorial on a way to do it, please share.

How to fix Constant Errors When Implementing Google OAuth Sign-in with Django

Django: subclass, separate class or entirely separate classes
I'm building a forum app in Django as a learning project. I'm unsure of how to approach the creation of Post objects. I want users to be able to post threads (i.e. new topic), I want users to be able to post replies to those threads as well as replying to other replies. I want to include features like reactions to posts, and replies. I'd appreciate some feedback on the different approaches I'm considering: My thinking is that, since the two types of posts are so similar, they should inherit common fields/methods from a parent class. I'm unsure how Django would represent that in the DB tbh. Intially this was an abstract class class Post(models.Model): post_body = models.TextField(max_length=2000) publish_date = models.DateTimeField("date posted") author = models.ForeignKey(User, on_delete=models.CASCADE) class ThreadPost(Post): post_title = models.Charfield(200) is_solved = models.BooleanField("is_issue_solved", default=False) class ReplyPost(Post): is_solution = models.BooleanField("is_this_the_solution", default=False) thread_post = models.ForeignKey(ThreadPost, on_delete=models.CASCADE) Later I started using this, based on a stackoverflow response. However, I'm finding it a bit clunky to work with, as I often have to filter by whether a post is a thread or a reply, and have to find the thread which a post replies to. In that case, just having seperate classes seems … -

This behavior seems incorrect as the voucher should only be listed once.its only happening journal Vouchar entry for eg: - as you can see the 100 rs transaction effects on both dr and cr side its journal Vouchar entry rest of the vouchar types working perfectly def get_sundry_creditors_coa_response(coa, start_date, end_date, user): invoices = Invoices.objects.filter(date__range=[ start_date, end_date], invoice_type='Purchase', company__users__email=user.email).order_by('date') respone = [] res_obj = {} for invoice in invoices: cost_entrys = CostEntry.objects.filter( invoice__id=invoice.id, is_included=True) for cost_entry in cost_entrys: res_obj = { "account": invoice.client_name.name if invoice.client_name else "", "date": invoice.date, "currency": invoice.currency_sar, "invoice_number": invoice.invoice_number, "vat_percent": 0, "fcy_amount": 0, "vat_amount": 0, "amount": 0, "dr_amount": 0, "cr_amount": 0, "net_amount": 0, "type": "Invoice", "voucher": "", "party_account": invoice.party_account.name if invoice.party_account else "", "job_no": invoice.job.job_number if invoice.job.job_number else "", "narrations": invoice.narration if invoice.narration else "", "branch": invoice.branch if invoice.branch else "", "language_name": coa.language_name if coa.language_name else "" } fcy_amount = float( cost_entry.fcy_amount if cost_entry.fcy_amount else 0.0) amount = float(cost_entry.amount if cost_entry.amount else 0.0) vat_percent = float( cost_entry.tax_group_code if cost_entry.tax_group_code else 0.0) vat_amount = float((vat_percent * … -
How to override queryset for newly added fieldset in Django Admin Panel
I have added "permissions" fieldset in my User model on Admin Panel, but when I try to add a User it takes a lot of queries due to permissions (500) in my case, I am not able to optimize the code because get_queryset is not executing while adding an object. I want to know how can I fetch all related permissions in add user form, so it should fetch all select related permissions to optimize the admin panel interface. -
Get values from request
I am trying to write values from a request.POST to a string format. By default, these always start with "epochs-NUMBER-". Therefore, I should draw a For loop so that a new line is created for each number. The complete request looks like that. But I only need the 'epochs-NUMBER-' values csrfmiddlewaretoken=hJmSuP3O6GmtwBeJhfqb99LaCVOKxgngGNIEqoqhQQR7tQELUVGHeXRXxfnRE1Ah&base-TOTAL_FORMS=1&base-INITIAL_FORMS=0&base-MIN_NUM_FORMS=0&base-MAX_NUM_FORMS=1000&base-0-time=25.06.2024+13%3A36%3A00&base-0-show_differences=on&base-0-show_null=1&source=Manual&epochs-TOTAL_FORMS=3&epochs-INITIAL_FORMS=3&epochs-MIN_NUM_FORMS=0&epochs-MAX_NUM_FORMS=1000&unit_selector=m&unit_selector=m&unit_selector=m&unit_selector=m&epochs-0-target_name=250.01.G&epochs-0-easting=55555&epochs-0-northing=5555&epochs-0-height=555&epochs-0-azimuth=&epochs-0-zenithangle=&epochs-0-slope_dist=&epochs-1-target_name=170.01.G&epochs-1-easting=44646&epochs-1-northing=6554&epochs-1-height=544&epochs-1-azimuth=&epochs-1-zenithangle=&epochs-1-slope_dist=&epochs-2-target_name=150.01.G&epochs-2-easting=78979878&epochs-2-northing=4645&epochs-2-height=455&epochs-2-azimuth=&epochs-2-zenithangle=&epochs-2-slope_dist= The request looks like that: def nmea_string(self, request, target_name): my_dict = {} keys = [] values = [] target_raw_string = ("PTER," + self.short_name + "_TRG," + target_name + "," + self.time.strftime("%Y-%m-%d %H:%M:%S") + "," + str(self.status_target)) for key, value in request.POST.items(): keys.append(key) values.append(value) for i in range(len(keys)): my_dict.update({keys[i]: values[i]}) for k, v in my_dict.items(): if k.startswith('epochs-0-'): if v == '': v = '-9999.999900' if k.startswith('epochs-0-target_name'): target_raw_string += "," + v else: target_raw_string += "," + v + ",0.000000" tg_checksum = self.get_checksum(target_raw_string) tg_nmea_string = "$" + target_raw_string + "*" + tg_checksum + "\n" nmea_string += tg_nmea_string return nmea_string The end result should look a bit like this: $PTER,TS_TRG,TP-008,2024-04-22 23:00:00,129,675666.252000,0.000000,252132.398000,0.000000,412.137000,0.000000,-9999.999900,0.000000,-9999.999900,0.000000,-9999.999900,0.000000*1F $PTER,TS_TRG,TP-009,2024-04-22 23:00:00,129,675704.440000,0.000000,252162.055000,0.000000,412.341000,0.000000,-9999.999900,0.000000,-9999.999900,0.000000,-9999.999900,0.000000*1A
