How do I format Django form CharFields to be next to each other one the same line?
Currently, I'm using a the Django Form class to create a form. I'm trying to make it so that all of the CharField fields have their own row, except for a few specific one's that I would like to share a row. These are the CharFields I currently have: class ExampleForm(forms.Form): example_1 = forms.CharField(max_length=20, required=False) example_2 = forms.CharField(max_length=20, required=False) example_3= forms.CharField(max_length=20, required=False) def __init__(self, *args, **kwargs): super(MetadataForm, self).__init__(*args, **kwargs) self.fields['example_1'].widget.attrs['style'] = 'width:15%;' self.fields['example_2'].widget.attrs['style'] = 'width:15%;' self.fields['example_3'].widget.attrs['style'] = 'width:15%;' Here is how they're rendered in the HTML: <label for="id_example_1">Example 1:</label> <input type="text" name="example_1" maxlength="20" style="width:15%;" id="id_example_1"> <label for="id_example_2">Example 2:</label> <input type="text" name="example_2" maxlength="20" style="width:15%;" id="id_example_2"> <label for="id_example_3">Example 3:</label> <input type="text" name="example_3" maxlength="20" style="width:15%;" id="id_example_3"> In an attempt to format example_1 and example_2 on the same line, I tried floating the labels to the left and then adding space between them by increasing the margin: #example_1, #example_2, #example_3 { float: left; margin-left: 100px; } However, while this formats the boxes very oddly: It also doesn't do anything for the labels. I'm not sure how to reference the labels since they don't have id values I can use. If there's a way that I can have example 2 and 3 formatted on the … -
How to make queries to remote Postgres in different views in Django?
I'm making a project where I need to access to remote databases and get data from it. I'm connecting to remote postgres database and getting list of all tables in my class-based view like so: try: # connect to the PostgreSQL serve conn = psycopg2.connect( host='host', database='db_name', user='username', password='password', port='port', ) # create a cursor cursor = conn.cursor() cursor.execute("select relname from pg_class where relkind='r' and relname !~ '^(pg_|sql_)';") rows = cursor.fetchall() # close the communication with the PostgreSQL cursor.close() except (Exception, psycopg2.DatabaseError) as error: print(error) Now, in another view I want to make other queries (like retrieving specific rows from specific table). How am I able to do that? The goal is to take all credentials from user's input in template to connect to db. Then on another template choose which table and which rows to use to get certain data. -

Exclude auto-generated files by Django within pre-commit-config.yaml using REGEX
Since the auto-generated Django files don't fulfill numerous pylint-requirements, my pre-commit checker fails: The files look usually like so: They seem to be located automatically in a sub-folder called "migrations": Now, I tried to leverage the pre-commit exclude expressions with a proper REGEX. This one seemed to work on an online REGEX-tester: [\w-]+\d+[^\\]*.py Here is the proof: Now, putting this into my pylint pre-commit checker does unfortunately nothing: I also tried to just exclude the "migrations" folder, but I could not find a working expression either. How can I make this work? -

How to use default logger and custom logger in django but avoid duplicate logs
I have two sets of APIs in a Django project that I want to use my custom logger. So in every viewset I will be doing logger.info(...) or logger.error(...) before the responses. Everywhere else in the project, like Admin pages and other tools, I'd like to leave the logging as it is for now. This is how I have defined my LOGGING in settings.py. LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'formatters': { 'standard': { 'format': 'ts=%(asctime)s level=%(levelname)s caller=%(filename)s:%(funcName)s:%(lineno)s %(message)s', 'datefmt': '%Y-%m-%d %H:%M:%S', }, }, 'handlers': { 'console': { 'class': 'logging.StreamHandler', 'formatter': 'standard', }, }, 'loggers': { 'django': { 'handlers': ['console'], 'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'), }, }, } The problem is that the way it is, the logging in the APIs is duplicated for every request, my logger and the existing django logger. How can I "disable" the default django logger in the APIs but keep it everywhere else? -
Testing a django `post_save` signal that includes function calls that occur after db transaction is committed
When django tests are running, database transactions are not committed. How do I test an event triggered by object creation but that happens after the db transaction has been committed? I have a Campaign model and the below post_save signal. Using Django TestCase it is difficult to assert that the functions within transaction.on_commit are called in the case when a new Campaign object is created. When the signal runs in the test context, it always thinks that an existing campaign object is being edited, not that one has been newly created. Therefore I cannot test the else branch of the if statement. How could I test the case when Campaign.objects.filter(pk=instance.pk).exists() is False? Signal: @receiver(post_save, sender=Campaign, dispatch_uid="apps.writing.signals.create_handwriting") def create_handwriting(sender, instance, **kwargs): """Whenever a campaign is created or updated, trigger the handwriting cloud function to (re)generate the handwriting image.

Share Django authentication for FastAPI
I have working Django project. Now i want to add FastAPI so at existing django templates i can make API requests to refresh data without reloading whole template (like tables for example). The question is how to connect FastAPI to existing django authentication system, so it can use sessions from db, so that user authenticate only once, when logging in to django project. Here some options i have investigated: Change django base authentication to oauth2, also set fastapi to oauth2 (though i desire to configure fastapi, not changing django) Fetch django sessions from db on each api request and verify user Both django and fastapi on the same server and can share the same db. Maybe some better options are possible. Please advice what would be the best approach to use django already authenticated user data with fastapi? Thx -

Why in DJANGO the Templates are not updated when I refresh the page with new data in the DB?
The problem is that when I change data through a form or by the django admin if it is saved in the database, but when redirecting to another view or refreshing the screen with f5 it does not show the changes in the user views unless I start session again or delete the cookies, something that for each change you have to perform this operation, however in the django admin views if everything is updated normally with a simple f5. This is very rare since the page has been working for more than 1 year without this problem and suddenly this happened. I'm using: Stevedore Nginx gunicorn 20.0.4 Django 3.1.4 python 3.9 sqlite 3 and bootstrap 4.6 for user views I thought it was just the update of my browser but in any browser the same thing happens I did not find a similar problem in any forum, I hope you can help me or give me an indication of what is causing this -
