Django Adding Random String In Static File Names
I have a Django (Wagtail CMS) website deployed using Apache WSGI. For some reason, the static files linked in the page source code is wrong. For example, the page's styling doesn't work because the page's HTML comes up as: <link rel="stylesheet" type="text/css" href="/static/css/styles.d0720c096b01.css"> The link /static/css/styles.d0720c096b01.css leads to a 404, but if I browse to /static/css/styles.css I can see my stylesheets. The random string d0720c096b01 is being added to all the static files. How do I fix this? -
DRF OpenAPI documentation omitting nested endpoints
In urls.py I specify a number of URLs. But only those with only one slash-separated "word" beyond api/ are actually included in the schema. E.g. an openapi schema generated from the code below will only document the /api/token/ endpoint. The (deprecated) corejson schema does include them. Is this because my endpoints are not OpenAPI compliant? urls.py urlpatterns = [ path("api/token/", auth_user_views.AuthUserView.as_view(), name="auth_user"), path( "api/token/refresh/", auth_user_views.AuthUserRefreshView.as_view(), name="token_refresh", ), url( r"^api/token/verify/$", jwt_views.TokenVerifyView.as_view(), name="token_verify" ), ] -
Django_filter: How to specify the fields from a Foreign Key using Multiple choice filter?
I have a database (django model) containing DNA sequences with certain informations (not relevant here) which are associated with a Foreign Key (species name)to species informations. I want to research the sequences via the species name using django_filter MultipleChoiceFilter. the problem is: the choices which appear to the users are the species id not the species name. I tried to define a custom class to only display species name however it does not change anything. Maybe I should specify something in the init() function ? Thank you for your help. Here are my models: Class Especes(models.Model): nom_espece = models.CharField(max_length=100,unique=True) famille = models.CharField(max_length=100) ordre = models.CharField(max_length=100) classe = models.CharField(max_length=100) embranchement = models.CharField(max_length=100) regne = models.CharField(max_length=100) pays = models.CharField(max_length=100) class Meta: verbose_name = 'especes' def _str_(self): return self.nom_espece class Sequences(models.Model): numero_sequence = models.IntegerField() sequences = models.CharField(max_length=1000000) gene = models.CharField(max_length=100) nombre_pdb = models.IntegerField()#check how to limit integer field ?? amorces = models.CharField(max_length=1000) espece=models.ForeignKey(Especes,on_delete=models.CASCADE,related_name='liste_sequence',default=None) auteurs = models.CharField(max_length=100) annee_publication = models.IntegerField() groupe_recherche = models.CharField(max_length=100) institut = models.CharField(max_length=100) class Meta: verbose_name = 'numero_sequence' def _str_(self): return self.gene` Here is my filters.py file: `class MyMultipleChoiceFilter(django_filters.ModelChoiceFilter): def label_from_instance(self, obj): return obj.nom_espece class SequencesFilter(django_filters.FilterSet): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) espece = MyMultipleChoiceFilter(queryset=Especes.objects.all(),label='Species') class Meta: model = Sequences fields … -
javascript file loading problem in a web browser, relating to mime types, context Django debug_toolbar concerning Django/debug_toolbar versions >=3.X
I have noticed, at some point last year, that the debug_toolbar is not present anymore. Now I have found the problem, but do not actually completely understand what is happening and why. The initial information is that I tried a lot of different version combinations for Django/delug_toolbar and there were no problems as the version number of both started by 2. However, the toolbar is not showing itself if a version number starts by 3. The toolbar 2.2 should work with Django version 3 or larger also. Now I have located the problem to be that toolbar.js is not loaded. There is a message in the developer tool's console: :8001/static/debug_toolbar/js/toolbar.js:1 Failed to load module script: The server responded with a non-JavaScript MIME type of "text/plain". Strict MIME type checking is enforced for module scripts per HTML spec. So I found the location of the toolbar.js under the static files folder of the debug_toolbar. The file is loaded in a template base.html (in folder env\Lib\site-packages\debug_toolbar\templates\debug_toolbar) There is a line: <script type="module" src="{% static 'debug_toolbar/js/toolbar.js' %}" async></script> I changed it to be: <script type="application/javascript" src="{% static 'debug_toolbar/js/toolbar.js' %}" async></script> And the change I made is quite obvious. But I do not understand … -
Django/HTML: Pre-populating "number" input fields with decimal values from a model
I'm writing code for editing infos about a product an user has already saved in our database. So I want to pre-populate the fields of the form with the 'old' infos. Everything works fine except for the prices that I can't get to be displayed. I understand that the problem is related to the decimals since the "weight" field (whole numbers) works fine. Here's the context in my view function (working fine, I can print the prices values on the console): context["old_title"] = selected_product.title context["old_weight"] = selected_product.weight context["old_dayprice"] = selected_product.price_day_tvac context["old_weekendprice"] = selected_product.price_weekend_tvac context["old_weekprice"] = selected_product.price_week_tvac context["old_monthprice"] = selected_product.price_month_tvac context["old_description"] = selected_product.text Here's the HTML input: <div class="col-md-3 multi-horizontal" data-for="dayprice"> <div class="form-group" data-children-count="1"> <label class="form-control-label display-7 font-weight-bold" for="website" >€ / day </label > <input type="number" class="form-control" name="dayprice" data-form-field="Dayprice" id="dayprice" placeholder="5" step="any" min="0" value= "{{ old_dayprice }}" /> <p class="font-italic font-weight-light"></p> </div> and here's the model's concerned fields: price_day_tvac = models.DecimalField(verbose_name="DAY - Medium season", default=0, max_digits=9, decimal_places=2) price_week_tvac = models.DecimalField(verbose_name="WEEK - Medium season", default=0, max_digits=9, decimal_places=2) price_weekend_tvac = models.DecimalField(verbose_name="WEEKEND - Medium season", default=0, max_digits=9, decimal_places=2 price_month_tvac = models.DecimalField(verbose_name="MONTH - Medium season", default=0, max_digits=9, decimal_places=2) I tried changing the 'steps'(do different values, 'any', removing it), placing a hard-coded value (with decimal or … -
Django-tenants error redirecting to correct tenant/schema
First, I'm not sure if it's a problem of the package itself or something that I'm doing wrong (I guess it's the second option). I followed all the instructions of documentation (here https://django-tenants.readthedocs.io/en/latest/use.html) and even tho I can't figure out what I'm doing wrong. I have a app 'costumers' which is held my tenant model. This app is on 'SHARED_APPS' right under 'django_tenants'. My app 'university' is on 'TENANT_APPS'. This app contains all the logic and it has my models.py. I managed to create tenants correctly, BUT, the problem occurs when I try to use any of my Api endpoints. Example: I created a tenant called university1 and this tenant has it's own schema on my PostgreSQL database. When I do a post request using an api (using this tenant 'university1'), django is trying to use a table which doesn't exist on my schema. I really don't know what I'm doing wrong. In my models.py (in my app 'university'), do I have to add anything there? For example class Meta: managed = False and db_table=name_of_table_on_database? This is a sample of it: from django.db import models from comum.models import * from datetime import datetime from django.utils.translation import gettext_lazy as _ from … -
Controlling access to HTTP API with Django as issuer
I have Django GraphQL deployed to AWS Lambda + API Gateway using the serverless framework. For authentication I have used the django-graphql-jwt package. It is working perfectly fine using the provided queries. I would like to move to the new API Gateway HTTP API as I only proxy traffic. I was wondering if there is any advantage of validating the provided token at the API Gateway level? If so, is there any way I can achieve that by defining django with this package as the issuer? -
Using Different Redis Database for Different Queues in Celery
I have a Django application that uses Celery with Redis broker for asynchronous task execution. Currently, the app has 3 queues (& 3 workers) that connect to a single Redis instance for communication. Here, the first two workers are prefork-based workers and the third one is a gevent-based worker. The Celery setting variables regarding the broker and backend look like this: CELERY_BROKER_URL="redis://localhost:6379/0" CELERY_RESULT_BACKEND="redis://localhost:6379/1" Since Celery uses rpush-blpop to implement the FIFO queue, I was wondering if it'd be correct or even possible to use different Redis databases for different queues like — q1 uses database .../1 and q2 uses database .../2 for messaging? This way each worker will only listen to the dedicated database for that and pick up the task from the queue with less competition. Does this even make any sense? If so, how do you implement something like this in Celery? -

Sentry Performance Monitoring for Django per Request

Django Form does not load MultipleChoiceField data from POST request

Why my exclude filter remove different objects from the "same" django query applied to a foreign key?
The following queries and classes are simplified. The final objective is to look for the best selling products, providers, categories and other types of infos that would be useful in reports. Let's start by (trying) to find the sum of all products that have been sold, i.e, where the sales note is not None: >>> Product.objects.exclude( ... orderitem__order__salesnote__isnull=True ... ).aggregate(quantity_sum=Sum("orderitem__quantity"))["quantity_sum"] 9507578 Now, let's look for the providers: >>> Provider.objects.exclude( ... product__orderitem__order__salesnote__isnull=True ... ).aggregate(quantity_sum=Sum("product__orderitem__quantity"))["quantity_sum"] 8849003 If I remove the exclude filter, both queries returns the same amount: 9835691 Right now the db only have one order without a sales note: >>> for order in Order.objects.filter(salesnote__isnull=True): ... for item in order.orderitem_set.all(): ... print(item.product, item.quantity) ...

Django FileField unable to save file
I'm currently trying to upload a file to my Django backend using the model InteractorFile, which has a FileField. This is the view I have written to do so: class FileView(APIView): parser_class = (FileUploadParser,) def post(self, request, format=None): # Get bytes from received file receivedFile = request.FILES['fileField'] my_bytes = receivedFile.file.read() f = open('./example.jpg', 'wb+') f.write(my_bytes) f.close() f = open('./example.jpg', 'rb') myFile = File(f) interactorFile = InteractorFile.objects.create(name='pepe', owner=request.user, fileField=myFile) return Response(status=status.HTTP_201_CREATED, data=FileSerializer(interactorFile).data) This is working correctly and saving the received content in a file called 'example.jpg'. However, I want to avoid creating a file and writing to it, because this is very slow. This is why I wanted to use the Django ContentFile class, given that it supposedly does the same as the File class, but can be supplied directly with bytes from the HTTP request. def post(self, request, format=None): # Get bytes from received file receivedFile = request.FILES['fileField'] my_bytes = receivedFile.file.read() myFile = ContentFile(my_bytes, name="example.jpg") interactorFile = InteractorFile.objects.create(name='pepe', owner=request.user) interactorFile.fileField.save(name="example.jpg", content=myFile) return Response(status=status.HTTP_201_CREATED, data=FileSerializer(interactorFile).data) This is saving the data in a file called 'None'. This should mean that I'm not passing the name to the FileField correctly. This has been driving me crazy and I would appreciate any help. It … -
psycopg2.errors.UndefinedTable: relation "functie" does not exist (table DOES exist)

I've set up an APIView for this, which for 1 table actually does work, but the same thing doesn't work for the other.

However, both tables 'user' and 'functie' do exist in my Postgres DB. Why does psycopg2 keep saying the relation doesn't exist? I've checked everywhere on spelling mistakes.

Python generate a message with number between each word
I have coded something that allows me to generate a text. My message is my input and it returns me a new message with numbers instead of spaces. Here is an example : The problem is that some words like "goal" are cut at the end of the line (it's a website so the size is never the same). Is there a way to adjust the number of numbers between each word so that it displays correctly? Here is the code : def generate_grid(message): final_message = [] message_split = message.split(" ") words = [] for word in message_split: words.append(list(word)) # if I want to use letter insstead of numbers upper_case_alphabet = string.ascii_uppercase lower_case_alphabet = string.ascii_lowercase for word in words: final_message.append('<strong>') for i in range(len(word)): final_message.append(word[i].upper()) final_message.append('</strong>') random_number = random.randint(1, 3) for _ in range(random_number): random_char = random.randint(0, 9) final_message.append(str(random_char)) return mark_safe(" ".join(final_message)) -
Cannot import Javascript file in other Javascript file
For a project, I'm using Django for my backend, HTML/CSS/JS for frontend. For one HTML page, I use two JS files: dom_creator.js and console_page.js. I would like to use the functions of dom_creator in console_page, but whatever I try, I cannot find the right statement to import (and many of the ES6 import statements even make my console_page.js to stop working). I also have a module imported to my HTML (console_module.js). In that file, I have no issue importing dom_creator.js with import {function1, function2} from "./dom_creator.js" How would I be able to import functions from dom_creator in console_page.js (which is not a module)? I've tried all suggestions on Stack Overflow, but none of them seem to work. -
