Pretty print django.db.models.JSONField in Django admin?
Django >= 3.1 supports a new JSONField model field. I am using one like this: from django.db import models class Example(models.Model): foobar = models.JSONField() I've also included this model in Django's admin section. However, the field is just a simple textarea with the JSON included, not pretty printed. How can I make sure the JSON displayed in Django's admin section is pretty printed, with indentation, like this: { "example": { "a": 1, "b": 2 } } -

Is updating a postgres database from an unsupported version important?
So far, I see only two reasons that make me consider an update from Postgres 9.4 (which is already an unsupported version). I want to use Django 3.1 for the development of a new web and this new version of Django does not support Postgres 9.4 anymore. I would have a new functionality and maybe an improved performance. Are there other, maybe more important reasons why to update? Should I care that it is an unsupported verion? And if yes, is it worth to update all the way to the newest stable version? -

Schema creation and migrations from Django Admin UI
I was searching about the specific need, but did not got many useful results, so i will just ask for any ideas, libraries, hints that you may have. So the idea I want to realize comes from a model that is totally unrelated to the Django app and it may change over time, based on some requirement changes. So i do not want the user to manually execute some SQL commands when changes occur, and i want him to do that over the Admin UI where he would edit some existing columns, constraints, add new ones, using the standard inputs that an admin gives (check boxes, selects etc). From the input he makes, the tables will be created (first time), altered after any change after it etc. So the schema he would work on would look something like this: Table -------------------------------- | id | table_name | table_type | -------------------------------- | 1 | table1 | type1 | -------------------------------- | 2 | table2 | type2 | -------------------------------- Column ----------------------------------------------------------------- | id | column_name | nullable | unique | primary_key | table_id | ----------------------------------------------------------------- | 1 | column1 | false | true | true | 1 | ----------------------------------------------------------------- | 2 | column2 | … -

Django Latest Timestamped Items from Many
I have a Model where there can be multiple instances of the same entry. They have their respective timestamps as I scrape the same data sources daily. I want to only receive the latest entries for each item. I wanted to approach this as grouping by the identifier of the items, which will result in groups of the same items but different timestamps, then get the latest from each group and combine this. My question is, how can this be done in Django? From what I have read I can use the "annotate()" function to GroupBy and then use "latest()" on each group. Is there any better way of accomplishing the same result or is this a proper approach? Thank you! -

Filtering Objects Using Other Objects - Queryset, Django
In my Django application, the user provides a unique product name which matches field of another object and then displays second object on the list (that the user sees). So the object's display condition looks something like this obj1.name == obj2.name It is extremely simple for one object but how to use it for get queryset (where the field of objects 1 is equal to the field of object 2)?

Django save nested data to Elasticsearch
I want to save nested data to elastic, I created model, document and serialize. Incoming Data(from twitter and parsed): {'created_at': '2020-10-26 20:00:14', 'tweetID': xxx, 'userID': xxx, 'userName': 'xxx', 'userScreenName': 'xxx', 'full_text': 'xxx', 'hashtag': ['xxx'], 'urls': ['xxx'], 'ioc': [ {'type': 'xxx', 'value': 'yyy', 'first_discovery': '2020-10-26 20:00:14', 'last_observed': '2020-10-26 20:00:14'}, {'type': 'kkk', 'value': 'mmm', 'first_discovery': '2020-10-26 20:00:14', 'last_observed': '2020-10-26 20:00:14'}]} My Model class: from django.db import models from django.utils.translation import ugettext_lazy as _ class TwitterPost(models.Model): created_at = models.DateTimeField( _('created_at'), blank=True, null=True, ) tweetID = models.CharField( _('tweetID'), blank=True, null=True, default=None, max_length=100, ) userID = models.CharField( _('userID'), null=True, blank=True, default=None, max_length=100, ) userName = models.CharField( _('userName'), null=True, blank=True, default=None, max_length=200, ) userScreenName = models.CharField( _('userScreenName'), null=True, blank=True, default=None, max_length=200, ) full_text=models.CharField( _('full_text'), null=True, blank=True, default=None, max_length=500, ) hashtag = models.CharField( _('hashtag'), null=True, blank=True, default=None, max_length=250, ) urls = models.CharField( _('urls'), null=True, blank=True, default=None, max_length=200, ) hashtag = models.CharField( _('hashtag'), null=True, blank=True, default=None, max_length=250, ) urls = models.CharField( _('urls'), null=True, blank=True, default=None, max_length=200, ) def __str__(self): return self.tweetID class TwitterPostIOCs(models.Model): ioc = models.ForeignKey(TwitterPost, related_name='tweetIOC', on_delete=models.CASCADE) type = models.CharField( _('type'), null=True, blank=True, default=None, max_length=100, ) value = models.CharField( _('value'), null=True, blank=True, default=None, max_length=100, ) first_discovery = models.DateTimeField( _('first_discovery'), blank=True, null=True, ) last_observed = models.DateTimeField( _('last_observed'), blank=True, … -
Django: More pythonic way of saving form data to existing model
I'm currently saving my new ModelForm values by iteration of each form's cleaned values after validation. Is there a better way of doing this? Note: 'Activity' model already contains data for given example record_form = AddRecordTimeFrame(request.POST) activity_form = EditRecordGeneral(request.POST) activity_form_2 = EditRecordChassisDynoTest2(request.POST) if all([activity_form.is_valid(), activity_form_2.is_valid(), record_form.is_valid()]): test_record = RecordModel.objects.get(id=1) activity_record = test_record.activity for field, value in record_form.cleaned_data.items(): setattr(test_record, field, value) for field, value in activity_form_2.cleaned_data.items(): setattr(activity_record, field, value) for field, value in activity_form.cleaned_data.items(): setattr(activity_record, field, value) I'd like to make use of the form's .save() but only change values of the model that are in the fields of the modelform.
