Why makemessages generates *.html.py file from my *.html in the component (django_components) and base.html template?
I am creating my Django website and using django_components in the project. Now I'm thinking about creating a multilingual site: I created the necessary translate tags, added an i18n loader, created a locale folder in the root of the project. Now I am running the following command: $> python manage.py makemessages --locale=en Today, this command is working correctly. But yesterday, when I was doing it, an error about the inability to read the file dropped out /component/my_widget/my_widget.html.py. Initially, there was no such file at all, there was only my_widget.html and my_widget.py , but this file was created when executing the command. Inside this file there were different sets of letters X and B of different lengths, and in structure it resembled tags from a template my_widget.html . The most interesting thing is that in this file I did not use the translate tag at all. Next is an example of this strange .html.py file: BBBB BBBBBB XXXX XXXXXX XXXXXXX XXXXX XX XXXXXXX XXXXXX XX XXX XX XXXX XXX XXX XXXX XXXXXXXXXXXXXXX XXX BB BBBBBBBBBBBBBBBBB BB BBBBBBBBBBBB XXXX XXXX XX XXXX XXXXXXX XXX XX XXXXXXXXXXXXXXXXXXXXX XXXXXXXX XXXX XXXXXXXXXXXXXXXXXX XXXX XXXXXX XXX XXXXXXXXXX XXXX XXXX XX XXXXXXXXXXXXXXXXXXXXXXXXXXX XX XXXXX XXXX X XXXXXXXXXXXXX … -
Why is simply adding "_id" suffix to a ForeignKey field automatically allowed in Django Serializer?
If I had the following model, I could set foo to foo_id by supplying foo_id = serializers.PrimaryKeyRelatedField(source='foo',queryset=Foo.objects.all() in the BarSerializer. from django.db import models class Bar(models.Model): foo = models.ForeignKey(Foo, on_delete=models.CASCADE) However, I can also set foo to foo_id as follows, without that specified line of code. from rest_framework import serializers class BarSerializer(serializers.ModelSerializer): # foo_id = serializers.PrimaryKeyRelatedField(source='foo',queryset=Foo.objects.all() class Meta: model = Bar fields = ['foo_id'] Why exactly can I provide 'foo_id' rather than 'foo' in the fields list here? One difference is that attempting to save a new Bar object with the BarSerializer results in django.db.utils.IntegrityError: (1048, "Column 'foo_id' cannot be null"), even when {foo_id: 1} is provided in the request data. -

Angular routes to localhost in k8s cluster
I have a problem with my Angular 15 Frontend app inside Minikube cluster. For deploying my app in Minikube, I add the k8s services URLs to environment files and Angular/Nginx sends me back to localhost - not to desired servcice URL. environment.development.ts export const environment = { production: false, serviceURL: 'http://backend.namespace.svc.cluster.local:8000', }; service.ts import { Injectable } from '@angular/core'; import { HttpClient, HttpHeaders } from '@angular/common/http'; import { Observable } from 'rxjs'; import { User } from './user'; import { environment } from '../../environments/environment' @Injectable({ providedIn: 'root' }) export class MainService { baseUrl = environment.serviceURL+'/user/' httpHeaders = new HttpHeaders; constructor( private http: HttpClient, ) { } user(user:any): Observable<User> { return this.http.get<User>(this.baseUrl) } } With these settings Angular sends me back to localhost, where I get an 404 error where cannot find the 'http://localhost:4200/user/' When I try to curl service url ( curl http://backend.namespace.svc.cluster.local:8000 ) from frontend pod I get a correct response. Can someone advise me how to correctly connect angular frontend with django backend, please? -
How to send a file response to a user in Django application after some processing
I'm working on a solution which translates CSV/TSV files from one language to the other. I've built a Django application that accepts the file and the target/source language(s) using a form. Once the user provides the data, the file is processed (which takes some time). Now I know we can return a fileresponse to the user. However, as I mentioned it takes time for the file to be translated and a new file is created which would contain the translated contents. And in the meantime, I don't want to make the user waiting on the form...waiting for the response. The models.py file is: from django.db import models from django.core.validators import FileExtensionValidator file_type_choices = [ ('CSV', 'Comma-Separated Values'), ('TSV', 'Tab-Separated Values') ] valid_extensions = ['tsv', 'csv'] # Create your models here. class FileModel(models.Model): file = models.FileField(upload_to="files", \ validators=[FileExtensionValidator(allowed_extensions=valid_extensions)]) file_type = models.CharField("Choose your file type", choices=file_type_choices,max_length=3) source_language = models.CharField("Choose the language in which file is", max_length=30) target_language = models.CharField("Choose the language to which you want to translate the file", max_length=30) the forms.py file: from django import forms from django.core.validators import FileExtensionValidator file_type_choices = [ ('CSV', 'Comma-Separated Values'), ('TSV', 'Tab-Separated Values') ] valid_extensions = ['tsv', 'csv'] class FileUploadForm(forms.Form): file = forms.FileField(allow_empty_file=False, \ validators=[FileExtensionValidator(allowed_extensions=valid_extensions)]) … -
Database structure on unknown column length excel
I have a program which user will import an excel of product details. It must include "barcode" and "name". But other columns is unknown and the length of column is also unknown. The program will be copy and paste to many client's PC, and each client product detail excel's may contain unknown + 2 columns (2 means the barcode and name). What will the database struture be on this case? Should I create a product table will defualt like 30 columns? "null" on non-used value? Even I create a product table with ID, barcode and Name. And create a "Product Extra Table" to left join the "product Table". I also need to create 30 columns on the "Product Extra Table". As the program will need to read the excel file, this operation will be process on runtime. I am using Django, I found that Django seem not able to support modify models during runtime? If I can modify the model during runtime, I can loop the excel headers and create a same column length model same as the product excel. -
Django Customusermodel was declared with a lazy reference
I am working on an app main and I want to have a custom login, that authenticates with email, not with username as normally in Django. For that I created the following model: class User(AbstractUser): username = None email = models.EmailField(('Email-Adresse'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] and added this model to the settings.py: AUTH_USER_MODEL = 'main.User' Then I replaced the user foreign key in my database: class BrainFeedback(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, blank=True, null=True, db_index=True) Running makemigrations worked perfectly fine, but python manage.py migrate triggers the following error: The field main.BrainFeedback.brain was declared with a lazy reference to 'main.user', but app 'main' doesn't provide model 'user'. What could be the problem? I was using a online guide to do these changes and I did everything how I should. -

Adding a boolean value to a search function
I have a multi-filter function that returns Clinic results based in 5 parameters. I want to add a 6th parameter which is a BooleanField (both in model and form). I want the field to return the corresponding elements if True, but if False, return all the elements according to the other search parameters independently of this BooleanField. if request.htmx: name = request.GET.get('name') city = request.GET.get('city') ward = request.GET.get('ward') speciality = request.GET.get('speciality') english = request.GET.get('english') print(f'english: {english}') if all([len(name) == 0, len(city) == 0, len(ward) == 0, len(speciality) == 0]): qs = None else: qs = Clinic.objects.filter(Q(name__icontains=name) & Q(city__icontains=city) & Q(ward__icontains=ward) & Q(speciality__icontains=speciality)) I tried to add the english variable to the queryset as Q(english_support=english) but without success. If I print out the result, it returns None if not checked, and on if checked. How can I add the condition that if None, return all the results according to the other Q parameters and if True just add it to the other conditions? -

Any of them is required. I'm having problems with rendering results when no content is entered in a field, as it will be an empty string and therefore return all values in the database.

How can I edit the message of the email sent by Wagtail when a page is submitted for moderation?
I'm trying to edit the content of the email sent by Wagtail when a page is submitted for moderation, I've dug into the Wagtail source code and it turns out there is a function called send_mail which actually sends the emails to all the subscribers when a page is sent for moderation, this function is called by another one called send_notification which takes some notification templates (HTML and txt files) depending on the type of action (submitted, approved, rejected) of the page, those templates contain the email content and I haven't found the way to override the content of those templates from my Wagtail project. If someone has done that before, I really appreciate your help. Thank you! I'm expecting being able to edit the content of the emails because I want to add some custom fields like comments. -

Django Equivalent of JSDocs?
I've been tasked to add an automated endpoint documentation tool for our Django codebase. It needs to produce html files that we can then host in our s3 buckets for internal reference. I thought drf-spectacular would be it, but it doesn't seem to actually produce html files, but only documentation for one's local environment. Is there a tool or library that can do this? Something like JSDocs or TypeDoc, where I can run a command, and dump html documentation files into an s3 bucket. Thank you! -
