Access django built in user
I'm currently trying to build a django application. I'm accessing django's built in user models and now want to access these to associate user input to the actual user. How would I go about accessing the user. So far I believe I would use django's ForeignKey, but I'm unsure on the correct reference? Thanks in advance -
When should I use annotations vs. model methods in Django?
I have a situation where I need to add additional data to the objects within a Queryset, and I have troubles understanding when it is really beneficial to perform queries that have annotations, over just implementing custom methods on the model class. As far as I know, when doing annotations all the work is done by the database engine and everything can be done in a single database hit (I think?). On the other hand, when implementing a method on the model class, additional queries might be performed if you need to get reverse lookups, or data from a foreign model. I just want to ask, is there any rule of thumb, or any guidance that you all consider for when to use one approach over the another? Especially if the annotations get really complex (e.g, using Q objects, Subqueries, GroupConcat, and so on) Thanks. -

How can i make my first form with a selected field prepopulate that field in a second form in Django
I'm new to Django, started learning it this week.

How to override M2M field names and models in Django with an existing database?
I'm using Django 3.1.3 and working with an existing postgresql database. Most of the models and fields names of this DB are badly chosen and/or way too long. Most of the time its easy to change them with some handy Django options like so : class NewModelName(models.Models): new_field_name = models.CharField(max_length=50, db_column='old_field_name') class Meta: managed=False db_table='database_old_table_name' But let say I want to change a M2M field name and the corresponding model name. I'd like to have something like : class Foo(models.Models): new_m2m_field_name = models.ManyToManyField('RelatedModel', blank=True, db_column='old_m2m_field_name') class Meta: managed=False db_table='foo_old_table_name' class RelatedModel(models.Models): name = models.CharField(max_length=50) class Meta: managed=False db_table='related_model_old_table_name' But if I do that, Django will throw an error stating django.db.utils.ProgrammingError: relation "foo_new_m2m_field_name" does not exist. It is like it is ignoring the db_column option. Any idea how I could get to a similar result ? Thanks! -
Where in Django can I run startup to load data?

Best theorically way to integrate some standalone apps into a web environment?
I've developed some python standalone apps that now I want to integrate into a web environment in order to make them more user friendly for my workmates, whom aren't used to CLI and the command shell. I've thought in remaking those apps as Django apps, using the Django REST framework, but I'm not sure if that way is the theoretically correct given the REST API meaning. For giving some examples, one of my apps takes some geometries from a geopackage, which is a kind of compact format for transferring geospatial information that could acts as a database for itself, and does some QA processes in order to ensure the geometries and data quality. Another of my apps takes some more geometries from the same geopackage and converts them into shapefiles or CAD files. In brief, my question is that it is theoretically correct to remake those apps as Django apps, using the Django REST framework, or maybe exists another options or framework that are more suitable to what I want to approach. -
