Connection error with Django and PostgreSQL in Ubuntu Server
I have a virtual machine running ubuntu server and I want to set a connection using Django in my pc and a postgre's database in ubuntu server. This is mi first time developing a database in server and I don't know if this is the correct way.

DJANGO JSON filtering nested value
I am trying to figure out how to filter out JSON in DJANGO when the structure looks like this: some random ID is like random generate id like pad1g12312-421df-2131 "data": { "steps":{ "some random ID":{ "name":"name1" } }, "process":{ "some random ID":{ "name":"PROCESS #1", } } I am trying to figure out how to get the name under execution and operation I tried follow with this post: Django JSONField filtering_ object.filter(data__steps__0__name='name1') object.filter(data__process__0__name='PROCESS #1') but it isn't working. I am assuming it's because the Random ID part doesn't work with the 0. Is there a way to do this? Also, I would like to combine the two in the same filtering, like object.filter(data__steps__0__name='name1' or data__process__0__name='PROCESS #1') Is it possible to do that? Thank you -
Add a FileField path to django
I have a map in my app and im trying to 'paint' some territories with kml files. I can get the outlined version if i hardcode the absolute path but since i have multiple kmls im trying to do it with a for loop with a field.kml.path (kml being the Filefield in my model) as per django instructions but it doesnt work .

Microservices framework for Django?
There are quite a few these frameworks for enterprise level players like Java (and Golang) It's a well known knowledge that many people use Django to implement each service within microservices architecture, but I am looking for something that sits on top of this, a framework of frameworks. Like cookiecutter type. Exposing data We all know to commonly expose a model over rest API is to use DRF, but setting it up is a chore, eg. manually creating ModelViewSet and setting up routers. In an non-public facing environment that assuming no auth needed, for the most basic setup, I just want to use decorator on the model, and it will do all the manual work behind the scene, eg. dynamically creating the viewset and register to urls, similar concept to viewflow's rest framework support. # in accounts app @soa_data_provider(...) class User(models.Model) .... which will default exposes the data in /api/accounts/models/user/ Consuming data Could potentially utilise django-rest-models like @soa_data_consumer(...) class User(models.Model): field = models.IntegerField() ... class Meta: # basic django meta Stuff verbose_name = 'Users' class APIMeta: pass Syncing data Referring to the @soa_data_provider decorator mentioned above, maybe using tools like rabbitmq to publish changes automatically over some convention naming/routes/etc etc, … -
Cannot alter tables after Django migration in posgres DB
I really need to know why in the world we cannot change the column types after we do the migrations to Postgres DB. I already created my models by python manage.py makemigrations then do migrate. Everything looks fine and tables are created on the postgres DB. class test_API(models.Model): IDnumber = models.IntegerField(unique = True, primary_key = True, null=False, editable = False, blank=True) State = models.CharField(max_length = 256, null = True) Exlcludmethod = models.CharField(max_length=256, null=True) class test_API_2(models.Model): Idnumber = models.Foreignkey(test_API, max_length = 256, blank=False, null = False) value = models.CharField(max_length=128, default="") last_updated = models.DateTimeField(auto_now=True) Lets say we want to make change to IDnumber column from Integerfield to Charfield. class test_API(models.Model): IDnumber = models.CharField(null=False, blank=False) State = models.CharField(max_length = 256, null = True) Exlcludmethod = models.CharField(max_length=256, null=True) and run the python manage.py makemigrations again return self.cursor.execute(sql) psycopg2.errors.DuplicateTable: relation "test_API" already exists How can we modify/change column types and do migrations.

Custom labels - Django auth user model - ModelForm
I'm trying to set custom labels for a UserCreationForm in Django. I've tried to follow the docs and searched on here. Only the first label changes via the labels dictionary I created. org.label at the top has been tested just to see if changes are made by setting a label outside of the dictionary. from django import forms from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User from django.utils.translation import gettext_lazy as _ class SignUpForm(UserCreationForm): email = forms.EmailField(required=True) org = forms.CharField(required=True) org.label = 'test org label' class Meta: model = User fields = ["username", "email", "org", "password1", "password2"] labels = { "username":_("xx-Username"), "email":_("xx-Email"), "org": _("xx-Organisation"), "password1":_("xx-Password"), "password2":"xx-Confirm Password" } The output I get is linked as an image. https://i.stack.imgur.com/7kGUY.png Many thanks. -

Hi guys! simple error with AUTH_USER_MODEL

django-exiffield: can't upload picture due to different format of 'CreateDate' and 'DateTimeField'
I'm a Django newbie, I hope you could help me. I'm developing a photo gallery app, and right now I'm trying to implement EXIF data extraction. It's working pretty well with pictures that were uploaded before the model migration, however, whenever I try to upload a new picture, I get this error: ValidationError at /admin/picture/picture/add/ ['“2021:11:12 15:26:56” value has an invalid format.

Is there an efficient way to add a csv file with many columns to a Django model?
I have a data frame with over 150 columns that I want to add to my Django database.

How to dynamically construct a hyperlink using Django named url
In my Django application I am using an ajax function to send some field values, do some processing (in views.py) and in the event of some exception (data mismatch etc), trying to construct a url for the user to use and navigate to the intended page (for further activities). Now, in the event of the exception (as described above), I am sending a pre-configured exception message (var_err) and a url (var_err_url) that would be constructed into a hyperlink for the user to make use of. Presently I am using the following scenario: Passing the two variables as json data bits (to display message text and dynamically creating a hyperlink, respectively) to the template and using jQuery to display the message along with the hyperlink (as shown hereunder): $('#id_err_message').html(var_err + ' <a href=" ' + var_err_url + '">Check</a>'); My set up works if I pass the url (variable var_err_url) as shown below: '/movement/planning/tpt_tenders/create/' i.e. the complete path. What I am trying to find out is: Is there a way to, instead, pass (Django) url name and dynamically create the hyperlink to have the same effect as shown under (as is done in Django templates), i.e.: <a href="{% url 'tpt_tender_add' %}">Add Tpt … -
Django JWT auth without migration
I have 2 projects written by Django : 1- Authentication(P1) and my_API(P2). in P1 I use DRF-simplejwt and 'dj-rest-auth' to register,login,logout,reset password ,... for P2 I need authentication. My opinion is that JWT does not use database for checking access token so It does not need to connect my users db to P2. But now I have error saying that I should migrate auth_user for rest_framework_simplejwt. What should I do now for checking permissions of P2 end points? Thanks for your attention :) -
Using Django's cache to store a model property
I have an image model with a foreign key back to the parent model. class MyImage(models.Model): parent = models.ForeignKey(ParentModel, related_name='images', on_delete=models.CASCADE) image = models.ImageField(upload_to='images') I am also using django-s3-storage to have these images served from a private S3 bucket. When I ask for the image url in a template using (this is a class based detail view, I also get the images in a class based list view): {% for image in object.images.all %} <img src="{{image.image.url}}" alt=""> {% endfor %} the value returned from url is a signed url and that's fine. I'd prefer not to make my bucket public. The problem is that this signed url is generated every time I get the url from the image model, which prevents the image from being cached in the browser as the signature changes on every request. This isn't ideal since these images will rarely change and I'd like them browser cached to reduce S3 costs. I am currently also using Django's built-in caching (in my case, I'm using database caching for the time being). The built-in caching will let me cache template fragments like so: {% for image in object.images.all %} {% cache 1440 object_image object %} <img src="{{image.image.url}}" alt=""> …
