Get the ratio of translation in a Django (or Python) project
Is there a simple way to get the ratio of translated messages in a Django project or by default in a Python project containing .po files? I have seen the Polib library API has a function to do that (https://polib.readthedocs.io/en/latest/api.html#polib.POFile.percent_translated) but it there and easy way to do this with adding this lib and make a script for the CI-check? -
Django migration is getting loose and is creating a separated file to add a field
I'm trying to run Django migration in my project, but something is not working fine, and I couldn't figure out what could be happening. The AuditableModelMixin entity is extended by almost all entities in my project and provides a couple of fields that are used for audit purpose. For all of than, the migrations is runing fine. Although, for the Contract model, the migration is creating the following two separated files: 0001_initial.py class Migration(migrations.Migration): initial = True dependencies = [ migrations.swappable_dependency(settings.AUTH_USER_MODEL), ] operations = [ migrations.CreateModel( name='Contract', fields=[ ('id', models.UUIDField(default=uuid.uuid4, editable=False, primary_key=True, serialize=False, verbose_name='identifier')), ('created_at', models.DateTimeField(auto_now_add=True, verbose_name='created at')), ('updated_at', models.DateTimeField(auto_now=True, verbose_name='updated at')), ('name', models.CharField(max_length=100, unique=True, verbose_name='name')), ('description', models.CharField(blank=True, max_length=1024, null=True, verbose_name='description')), ('created_by', models.ForeignKey(blank=True, db_column='created_by', null=True, on_delete=django.db.models.deletion.PROTECT, related_name='contract_created_by', to=settings.AUTH_USER_MODEL, verbose_name='created by')), ], options={ 'verbose_name': 'contract', 'verbose_name_plural': 'contracts', 'db_table': 'sacv"."contract', }, ), ] 0002_auto_20200524_1912.py (the sequence will change, that's ok) class Migration(migrations.Migration): initial = True dependencies = [ migrations.swappable_dependency(settings.AUTH_USER_MODEL), ('contract', '0001_initial'), ('jurisdiction', '0001_initial'), ('state', '0001_initial'), ] operations = [ migrations.AddField( model_name='contract', name='jurisdictions', field=models.ManyToManyField(related_name='contracts', through='jurisdiction.Jurisdiction', to='state.State'), ), migrations.AddField( model_name='contract', name='updated_by', field=models.ForeignKey(blank=True, db_column='updated_by', null=True, on_delete=django.db.models.deletion.PROTECT, related_name='contract_updated_by', to=settings.AUTH_USER_MODEL, verbose_name='updated by'), ), ] I don't know why, it is putting the updated_by into a separated file.

I have constants defined in a Django model class. How can I access the constants in a template?
I have a model class with a choice field and its possible values defined as constants, as recommended in https://docs.djangoproject.com/en/3.0/ref/models/fields/#choices class Student(models.Model): FRESHMAN = 'FR' SOPHOMORE = 'SO' JUNIOR = 'JR' YEAR_IN_SCHOOL_CHOICES = [ (FRESHMAN, 'Freshman'), (SOPHOMORE, 'Sophomore'), (JUNIOR, 'Junior'), ] year_in_school = models.CharField( max_length=2, choices=YEAR_IN_SCHOOL_CHOICES, default=FRESHMAN, ) In regular Python code (e.g. in a view), I can easily use the constants like so: if my_student.year_in_school == Student.FRESHMAN: # do something My question is: can I do something like this in a template as well? Something like {% if student.year_in_school == Student.FRESHMAN %} Welcome {% endif %} ... this works if I hard-code the value 'FR' in the template, but that kind of defies the purpose of constants... -
How to create random slug in Django
I have a Django app that will create a contract between two people. The user creates the contract and, upon creation, a random url-safe string is generated using secrets. However, when I create more than one instance of a Contract, the slugs are the same. The only way to get a different randomly generated string is to restart my server. What am I doing wrong? Here's the part that matters in my models.py slug = models.SlugField( default=secrets.token_urlsafe(64), editable=False, blank=False ) Here are the last three Contracts I created. Changing the values of the other fields doesn't change the slug. { "model_email": "POOP@pooop.com", "shoot_location": "Atlanta, GA", "shoot_date": "2020-05-24", "model_name": "", "created_at": "2020-05-24T19:24:20.220845Z", "sent_completed_to_model": null, "sent_completed_to_photographer": null, "photographer": 1, "signed": false, "slug": "Dqyk5-kDzE219_-abRKABETRuOCGOBxzvFVrXZaUGEe8ZLva6i6tdwUYMksSvKJ_BEABV_Vt1H_ttZ6p-yzRyg" }, { "model_email": "POOP@pooop.com", "shoot_location": "Atlanta, GA", "shoot_date": "2020-05-24", "model_name": "", "created_at": "2020-05-24T19:24:21.216218Z", "sent_completed_to_model": null, "sent_completed_to_photographer": null, "photographer": 1, "signed": false, "slug": "Dqyk5-kDzE219_-abRKABETRuOCGOBxzvFVrXZaUGEe8ZLva6i6tdwUYMksSvKJ_BEABV_Vt1H_ttZ6p-yzRyg" }, { "model_email": "POOP@pooop.com", "shoot_location": "Atlanta, GA", "shoot_date": "2020-05-24", "model_name": "", "created_at": "2020-05-24T19:24:22.120845Z", "sent_completed_to_model": null, "sent_completed_to_photographer": null, "photographer": 1, "signed": false, "slug": "Dqyk5-kDzE219_-abRKABETRuOCGOBxzvFVrXZaUGEe8ZLva6i6tdwUYMksSvKJ_BEABV_Vt1H_ttZ6p-yzRyg" } -

Render errors while trying to load Django templates
I'm receiving the error "render() got an unexpected keyword argument 'renderer'" while I try to run my Django web app. When I remove the error shown, the app runs bu without some fields and looks like this.

How to "link" already uploaded images to ImageField in Django?
I have models like: class Symbol(models.Model): slug = models.SlugField(unique=True) #uniqe name = models.CharField(max_length=255, unique=True) imgslug = models.CharField(unique=False, max_length=255, blank=True) #uniqe def __str__(self): return self.name class Platform(models.Model): name = models.CharField(max_length=50, unique=True) def __str__(self): return self.name class PlatformImages(models.Model): symbol_id = models.ForeignKey('Symbol', on_delete=models.CASCADE,) platform_id = models.ForeignKey('Platform', on_delete=models.PROTECT,) class Meta: indexes = [ models.Index(fields=['symbol_id', 'symbol_id']), ] constraints = [ models.UniqueConstraint(fields=['symbol_id', 'platform_id'], name='unique_symbol_img_per_platform') ] def __str__(self): return str(self.platform_id) def get_platform_name(self): return self.platform_id I have folders per platform in media folder like: media/apple/, media/google/, media/twitter/ ,etc. Inside each folder there are ~1000-3000 images, named as "imgslug" for almost each Symbol.

Setting up a search function in my Django app
Quick question: I made a search bar in my Django app. It works if I type in first or last name. But when I try AND & it doesn't work. Here's what I have: def names(request): all_names = name.objects.all search_term = "" if 'search' in request.GET: search_term = request.GET['search'] all_name = name.objects.filter( Q(first__startswith=search_term) | Q(last__startswith=search_term) return render(request, "about.html", {'all_names': all_names, 'search_term': search_term}) This works as far as OR is concerned but when I slide the & in place of the | it looses functionality. I'm stumped. According to the Django docs, & should automatically include both. I just want to be able to type in both first and last name in the search bar. -
How to i grab data inside my database without inserting?
I am very new to django and I am just messing around to get the hang of it. When I run my POST request, my data inserts the data to database then gets the data column that was inserted. However, I am wondering, why it is inserting and only grabbing the data column that was inserted. Shouldn't my code grab all the data from Users and not insert the data? I know I can use GET request instead of POST but still, I am wondering why it is functioning like this and how I can fix my code?

Is Model.clean() being called before form_valid()?
I'm new to Django and I'm trying to make use of the CreateView CBV. I have the following Model: class Child(models.Model): # one of user and session must be populated user = models.ForeignKey(settings.AUTH_USER_MODEL, models.CASCADE, 'children', null=True, blank=True) session = models.ForeignKey(Session, models.CASCADE, 'children', null=True, blank=True) ... def clean(self): super().clean() if (self.user is None) and (self.session is None): raise ValidationError('Either user or session must be populated.') Then I have the following CreateView: class ChildCreateView(CreateView): model = Child fields = ['name','gender','age'] ... def form_valid(self, form): form.instance.user = self.request.user form.instance.session = self.request.session return super(ChildCreateView, self).form_valid(form) However, when I navigate to the view in my browser and try to create a new Child using the form, I see "Either user or session must be populated" after pressing submit. Based on what I've read in the Django documentation it seems that the right place to assign Model.user is in ChildCreateView.form_valid(), but I don't seem to be getting the chance to do so. Instead, ChildCreateView.form_invalid() is getting called, evident from a print() statement I put in there. What am I missing here? I thought Form.save() gets called in ChildCreateView.form_valid(), so is Child.clean() getting called before ChildCreateView.form_valid()? Thanks very much! -

Django: Couldn't import JavaScript files from static directory. (Jinja2)
I just started Django and I'm trying to import JavaScript Files from static directory. So basically I was working on a Flask project for some time, so to import javascript file I was always using - {{ url_for('.static', filename='js/js_file1.js' }}. Now I realized that I need to use other methods as - {% static 'main/js/js_file1.js' %}. So after some time, I was able to import my css files with - <link rel="stylesheet" href="{% static 'main/css/styles.css' %}">, they are in static/main/css/files..., although my js files are in static/main/js/files.... But for some reason, the JavaScript files won't import themselves. I'm importing them with - <link rel="application/javascript" href="{% static 'main/js/bootstrap.min.js' %}">. Here's the network log from Developer console, as I can see there are no JS files on their way to import themselves. And here's the Server Log from the running server on cmd. Developer Console Log. My settings.py file has this static_url, which I guess specifies the static folder. # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/3.0/howto/static-files/ STATIC_URL = '/static/' My whole HTML File. -

Should the data from API be saved to the database or just call API everytime when data is needed for a website
Please assume I have no experience in developing the structure of websites. I am currently working on a website that displays data fetched from an API. (I use Django and python for the web app) I want to display the current Covid-19 data and analyze the trend in graphs and charts. I am able to grab the data from the API, but question is for a site like that needs an update on the numbers on a daily basis, what is the best practice for retrieving data. Should I be saving the api data to my database for easier access or should I just call the API everytime when the web page is visited (which is already a necessity due to the day to day update) and process data? (Performance wise or easily of processing data.) I would appreciate if anyone would share their experience. -

While in the development environment, I had to run three commands to run Django server, celery and celery beat python manage.py runserver celery -A qcg worker -l info celery beat -A qcg worker -l info Where qcg is my application. My Dockerfile has following uwsgi configuration EXPOSE 8000 ENV UWSGI_WSGI_FILE=qcg/wsgi.py ENV UWSGI_HTTP=:8000 UWSGI_MASTER=1 UWSGI_HTTP_AUTO_CHUNKED=1 UWSGI_HTTP_KEEPALIVE=1 UWSGI_LAZY_APPS=1 UWSGI_WSGI_ENV_BEHAVIOR=holy ENV UWSGI_WORKERS=2 UWSGI_THREADS=4 ENV UWSGI_STATIC_MAP="/static/=/static_cdn/static_root/" UWSGI_STATIC_EXPIRES_URI="/static/.*\.[a-f0-9]{12,}\.(css|js|png|jpg|jpeg|gif|ico|woff|ttf|otf|svg|scss|map|txt) 315360000" USER ${APP_USER}:${APP_USER} ENTRYPOINT ["/app/scripts/docker/entrypoint.sh"] The entrypoint.sh file has exec "$@" I have created the ECS task definition and in the container's command input, I have uwsgi --show-config This starts the uwsgi server. Now I'm running 1 EC2 instance in the cluster and running one service with two instances of the task definition. I couldn't figure out how to run the celery task and celery beat in my application. Do I need to create separate tasks for running celery and celery-beat?
