Django doesn't save all modelform fields in database
I customized the default django user model to make email required and username optional. I have a form for users to enter info and create an account. They enter email, first name, last name, password, confirmation password and check the terms/conditions box. All of these fields are required. In my view, I validate and clean the data and save the user to the database. This was working with a SQLite database and default project layout via the admin tool. Then I decided to use the project layout recommended in two scoops of django. I got the site working again except when I submit a user signup form, it saves the user in the database with an email and password but it doesn't save the first name or last name. I confirmed that first name and last name are being passed to the view. This makes sense because it was working previously. Maybe there's a setting somewhere that needs updating after the project layout change? I'm really not sure what's happening because it's saving user info to the database, just not all the user info. Any help would be greatly appreciated! This is my first real django project and I'm stumped … -

How do I write a BeautifulSoup strainer that only parses objects with certain text between the tags?
I'm using Django and Python 3.7. I want to have more efficient parsing so I was reading about SoupStrainer objects. I created a custom one to help me parse only the elements I need ... def my_custom_strainer(self, elem, attrs): for attr in attrs: print("attr:" + attr + "=" + attrs[attr]) if elem == 'div' and 'class' in attr and attrs['class'] == "score": return True elif elem == "span" and elem.text == re.compile("my text"): return True article_stat_page_strainer = SoupStrainer(self.article_stats_html_match) soup = BeautifulSoup(html, features="html.parser", parse_only=article_stat_page_strainer) One of the conditions is I only want to parse "span" elements whose text matches a certain pattern. Hence the elem == "span" and elem.text == re.compile("my text") clause. However, this results in an AttributeError: 'str' object has no attribute 'text' error when I try and run the above. What's the proper way to write my strainer? -

Are there minimal footprint ways to integrated a field into an existing model (3rd party)?
I was wondering if there was a way to take an existing model and change the default id = AutoField into id = UUIDField. I have tried injecting the UUIDField through migrations, but I get a couple of issues. It doesn't like changing from int to uuid for the id and whenever I do a makemigrations it removes the key since the model reflects different, thus removing it. This is already a lot of monkey patch, which could easily break on its own if things didn't work perfectly. Migration example: def gen_uuid(apps, schema_editor): MyModel = apps.get_model(APP_NAME, MODEL_NAME) for row in MyModel.objects.all(): row.uuid = uuid.uuid4() row.save(update_fields=['uuid']) # https://stackoverflow.com/a/29587968/1294405 class Migration(migrations.Migration): def __init__(self, name, app_label): super(Migration, self).__init__(name, APP_NAME) replaces = ((APP_NAME, __module__.rsplit('.', 1)[-1]),) dependencies = [ ('APP_NAME', '0004_auto_20190222_1551'), ] operations = [ migrations.AddField( model_name=MODEL_NAME, name='uuid', field=models.UUIDField(blank=True, null=True), ), migrations.RunPython(gen_uuid), migrations.AlterField( model_name=MODEL_NAME, name='uuid', field=models.UUIDField(unique=True) ) ] I tried a couple different variants of inheriting, in hopes to get it to function properly. It works almost, for the most part, except when it got time to doing stuff with a custom manager. Most of the methods internal dealt with its model instead of the wrapper I made. Wrapper Example: class MyModel(3rdPartyModel): uuid = models.UUIDField( … -
Python3 + Gunicon 19.9 + Django 2.0 does not print my logs, but print django.request
I added a lot of logs to my django app, but non is printed.. My logs are printed to std when I do not use gunicorn (just manage.py runserver ) python manager.py runserver log : 2019-02-22 16:36:13,973 apscheduler.scheduler #INFO 162 Scheduler started 2019-02-22 16:36:13,974 management.startup_tasks #INFO 14 Scheduling Test task, to run every 5 seconds 2019-02-22 16:36:14,029 apscheduler.scheduler #INFO 878 Added job "Test" to job store "default" The following is my Django logging setting LOGGING_CONFIG = None logging.config.dictConfig( { "version": 1, "disable_existing_loggers": False, "formatters": { "console": { # exact format is not important, this is the minimum information "format": "%(asctime)s %(name)-12s #%(levelname)-3s %(lineno)d %(message)s" } }, "handlers": { "console": {"class": "logging.StreamHandler", "formatter": "console"} }, "loggers": { "": {"level": logging.INFO, "handlers": ["console"]}, "scheduler": { "level": logging.INFO, "handlers": ["console"], # required to avoid double logging with root logger "propagate": False, }, "django.request": { "handlers": ["console"], "level": logging.INFO, # change debug level as appropiate "propagate": False, }, }, } ) and this is no command : pipenv run gunicorn scheduler.wsgi:application --log-file - yet the only log I see [2019-02-22 16:32:17 -0800] [44478] [INFO] Starting gunicorn 19.9.0 [2019-02-22 16:32:17 -0800] [44478] [INFO] Listening at: http://127.0.0.1:8000 (44478) [2019-02-22 16:32:17 -0800] [44478] [INFO] Using worker: sync … -
Use Django Migrations to delete a table
I am moving from Rails to Django and have an existing database. I created models.py via python manage.py inspectdb > models.py, made changes, and tested some endpoints. Everything seems fine. I then ran python manage.py makemigrations and migrate to make the initial django mirgation. I noticed an old Rail's specific Model / table called ArInternalMetadata / ar_internal_metadata. I figure I could easily remove the table by simply removing the model from models.py and rerun makemigrations however when I do that, django just says No changes detected. Running migrate doesn't remove the table either.
