Django ORM - Primary key not available after save while using UUIDField and RandomUUID In Postgres
For a project I'm working on, in one of the models i am using models.UUIDField for primary key with the default value set to django.contrib.postgres.functions.RandomUUID Here's my model. from django.contrib.postgres.functions import RandomUUID from django.db.models import JSONField class NewsItem(models.Model): id = models.UUIDField(primary_key=True, default=RandomUUID()) title = models.ForeignKey(RichText, models.DO_NOTHING, related_name='+', null=True) subtitle = models.ForeignKey(RichText, models.DO_NOTHING, related_name='+', null=True) excerpt = models.ForeignKey(RichText, models.DO_NOTHING, related_name='+', null=True) text = models.ForeignKey(RichText, models.DO_NOTHING, related_name='+', null=True) image = models.ForeignKey(ImageObject, models.DO_NOTHING, related_name='+', null=True) priority = models.IntegerField(null=True, default=0) frequency = models.IntegerField(null=True, default=1) text_effects = JSONField(blank=True, null=True, default=dict) scroll_speed = models.IntegerField(null=True, default=1) scroll_direction = models.IntegerField(null=True, default=0) created_at = models.DateTimeField(blank=True, null=True, auto_now_add=True) updated_at = models.DateTimeField(blank=True, null=True, auto_now=True) class Meta: managed = True db_table = 'news_items' The issue here is that i need to immediately access the primary key after the object has been inserted into the database, however trying to access pk or id after calling save simply returns a literal string RandomUUID() In [1]: from media.models import NewsItem In [2]: n = NewsItem() In [3]: n.save() In [4]: n.id Out[4]: RandomUUID() In [5]: str(n.id) Out[5]: 'RandomUUID()' However, if i issue a query like model.objects.first() or model.objects.last() and then access the id or pk of the returned instance, it works as expected.

Creating Dynamic Form Fields in Django ModelForm
I am looking to search the instance, check a value in a specific field and then return a list for the field to Meta but it doesn't appear the __init__ can return anything. How can I make a dynamic form that based on a value in a field, shows only a predetermined other fields.

I have over 100 fields that I would need to make visible and do not want to do this in a hack way in the template. It seems like JS is the best approach but I have 0 experience in JS. class Inspection_ResultForm(forms.ModelForm): #work on this tomorrow def __init__(self, user, *args, **kwargs): super( Inspection_ResultForm,self).__init__(*args, **kwargs) #if user.groups.filter(name='Operations Manager').exists(): fields_list = ["subgrade_00_title", "subgrade_00_weight", "subgrade_00_1_star", "subgrade_00_2_star", "subgrade_00_3_star", "subgrade_00_4_star", "subgrade_00_5_star", "subgrade_01_title", "subgrade_01_weight", "subgrade_01_1_star", "subgrade_01_2_star", "subgrade_01_3_star", "subgrade_01_4_star", "subgrade_01_5_star" ] if self.instance.inspection_request.sample.order.specification.subgrade_02_weight != None: fields_extends = ["subgrade_02_title", "subgrade_02_weight", "subgrade_02_1_start", "subgrade_02_2_star", "subgrade_02_3_star", "subgrade_02_4_star", "subgrade_02_5_star"] fields_list.extend(fields_extends) print(fields_list) fields = fields_list return fields class Meta: model = Inspection_Result fields = ('subgrade_00_title', 'subgrade_01_title',) #would like this to be equal to field list calculated in __init__ -

Django <div>{% block content %}
This is probably a silly question, but can you put a <div> stage around Django's {% block content %}? <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Title</title> {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'property/style.css' %}"> {% block head %} {% endblock %} </head> <body> <div class = "row"> <div class = "column left"> {% block left %} {% endblock %} </div> <div class = "column center"> {% block center %} {% endblock %} <div class = "column right"> {% block right %} {% endblock %} </div> </div> </body> <HTML> and my CSS * { box-sizing: border-box; } body { color: var(--text_color); background-color: var(--background_color); font-family: var(--font); font-size: var(--font_size); } .column { float: left; padding: var(--padding); height: 300px; } .left, .right { width: 25%; } .center { width: 50%; } .row:after { content: ""; display: table; clear: both; } I am trying to make each {% block %} be a column without having to write the <div> for each template. However, my HTML output is stacking them on top of each other instead of side by side. -
Many to many relationship does not work with django-safedelete as i want
I am using a library called django-safedelete to avoid permanently deleting records from the database, the technique is called "safedelete". Here is the documentation of the library https://django-safedelete.readthedocs.io/en/latest/managers.html I have a problem and it is that when I softdelete a record in the intermediate table between Actor and Film (Participation) the QuerySet ignores it completely, I mean when I execute a query to know in which film an actor has been, the Queryset ignores that the intermediate register that links the actor and the film is softdelete and shows in any case the films in which the actor has participated. here is an example of what happens: >>> Actor.objects.get (pk = 1) <Actor: Actor object (1)> >>> Film.objects.get (pk = 1) <Film: Film object (1)> >>> Participation.objects.all_with_deleted (). Values ('id', 'actor', 'film', 'deleted') <SafeDeleteQueryset [{'id': 1, 'actor': 1, 'film': 1, 'deleted': datetime.datetime (2021, 9, 4, 0, 43, 50, 125046, tzinfo = <UTC>) }]> >>> Actor.objects.get (pk = 1) .films.all () <SafeDeleteQueryset [<Film: Film object (1)>]> As you can see, it ignores that the participation record is softdelete and also shows the film in which the actor participated, what I need is not to show that the actor participated in that … -
