Change AWS S3 File Path naming convetion Django Storage
A S3 Bucket URL format of a bucket is either of below two options: http://s3.amazonaws.com/[bucket_name]/ http://[bucket_name].s3.amazonaws.com/ I am using django storages to store files in S3.

How to make postgres database accessible to another system?
So I'm using Django and Postgres for my project. I am new to integrating database using postgres with django. I connected the django project to my postgres database on my system.However, I want another person to manage the database and hence allow access to him to my database. I can see the tables through pgadmin 4 in my system, all of it being password protected and exclusive to my system. How can another person access this database using his pgadmin and his own password? For eg-dbsqlite has a file which is stored in project folder, which when shared can be accessed by another person with whom I share the code and project folder. Is such a thing possible with postgres using pgadmin administrator? If not how would I make this possible? -

Can I use django fileds values in def functions?
I am trying to make a function to resize images before upload. I found something on interent and it is working but I want to improve it. Instead of having the output_size = (320, 560) [as default value always] I would like to have some django fields and change it every time I need from django admin. This is why I added image_height and image_width fields. In my way of thinking doing this was the solution output_size = (image_height, image_width) but it doesnt work output_size = (image_height, image_width) NameError: name 'image_height' is not defined How can I use image_height and image_width fields and use add the values to output_size My models.py from __future__ import unicode_literals from django.db import models from django.urls import reverse from PIL import Image def upload_location(instance, filename): return "%s/%s" %('image/service', filename) # Create your models here. class Services(models.Model): title = models.CharField(max_length=120) content = models.TextField(null=True, blank=True) image = models.ImageField(upload_to=upload_location, blank=True, null=True) image_height = models.PositiveIntegerField(default=320) image_width = models.PositiveIntegerField(default=560) def save(self, *args, **kwargs): super().save(*args, **kwargs) img = Image.open(self.image.path) if img.height > 320 or img.weight > 560: output_size = (image_height, image_width) img.thumbnail(output_size) img.save(self.image.path) def __unicode__(self): return self.title def __str__(self): return self.title -
Django Accessing external Database to get data into project database
i'm looking for a "best-practice" guide/solution to the following situation. I have a Django project with a MySql DB which i created and manage. I have to import data, every 5 minutes, from a second (external, not managed by me) db in order to do some actions. I have read rights for the external db and all the necessary information. I have read the django docs regarding the usage of multiple database: register the db in settings.py, migrate using the --database flag, query/access data by routing to the db (short version) and multiple question on this matter on stackoverflow. So my plan is: Register the second database in settings.py, use inspectdb to add to the model, migrate, define a method which reads data from the external db and add it to the internal (own) db. However I do have some questions: Do i have to register the external db if i don't manage it? (Most probably yes in order to use ORM or the cursors to access the data) How can i migrate the model if I don't manage the DB and don't have write permissions? I also don't need all the tables (around 250, but only 5 needed). (is … -

(Django REST Framework) Adding field to a model at creation time
I'm making a weather api. I have 2 models: Location and Parameters. Parameters are properties like humidity, temperature, etc of Location. When I added a Location, I also want to add some default Parameters to it. When the new Location is displayed, I want an Aggregation field to be shown which is the Average, Sum, Min and Max of the available parameters. My problem is I'm saving the new Location before adding default Parameters so the Aggregation field of the Location doesn't have any data about the its Parameter values. Could I do something like after creating the default Parameters, go back to Location and somehow add the Aggregation? I really appreciate any help!! Here is what I did: Models class Location(models.Model): name = models.CharField(max_length=25, unique=True) description = models.CharField(max_length=64, blank=True) longitude = models.FloatField(blank=True, null=True) latitude = models.FloatField(blank=True, null=True) class Meta: verbose_name_plural = 'locations' def __str__(self): return self.name class Parameter(models.Model): name = models.CharField(max_length=25) unit = models.CharField(max_length=10, blank=True) values = models.JSONField(default=list, blank=True) _location = models.ForeignKey(Location, on_delete=models.CASCADE, related_name="parameters" ) def __str__(self): return self.name Serializers from .helper import add_location, aggregate, get_parameter_values, add_parameter class ParameterSerializer(serializers.ModelSerializer): aggregation = serializers.SerializerMethodField() class Meta: model = Parameter fields = ('id', 'name', 'unit', 'aggregation', 'values') def get_aggregation(self, obj): return aggregate(obj.values) … -

Django generate FTP download link
I have a model which contains a FileField that is connected to a FTP server (using this doc). Files are uploaded using Django admin.
