How to have a Python Django map with a satellite view using from django.contrib.gis.db import models?
I know python and I know a bit of Django. Lately I have been trying to upgrade my maps that I use in my app to a satellite view. Right on my map I am able to draw multiple polygons and save it to the database (postGres). I am using the following to draw the map: from django.contrib.gis.db import models ... ... myMap = models.MultiPolygonField(verbose_name="Boundaries Map", null=True, blank=True, srid=4326) The only thing I wanted to do is instead of having the map View have a Satellite view. Does anyone know any way of doing it? -

Django Templates vs React - Already started down the templates route
I'm currently in the process of learning Django to make a web application for my workplace. I initially had the thought of just learning Django first to get the hang of it, then once I had the core logic in place I would then move over to a React for the UI (also need to learn how to use React), instead of templates. I'm now at the point where I could switch, but I've now only just discovered that I should be developing the backend with the Django REST framework to provide APIs for React (and other front ends). Is this something I can easily transfer to? Or is there a way to use React with my existing Django setup? I'm on a slightly tight timeframe and don't exactly need the core features of React right now. Is it better to get the main web application online sooner with Templates (continuing development down that route) or transition now to React and the REST API and finish the rest of the features after? Will it become too big of a task down the track to transition? -

How to make graphql query that can find "latest" or "min" or "max"
I'm trying to use graphql with python to retrieve the latest item added to a temperature table. The temperature table has 2 columns: timestamp and value. My models.py is: from django.db import models class Temperature(models.Model): timestamp = models.DateTimeField(auto_now=True) value = models.FloatField() def __str__(self): return f"the value:time is {self.value}:{self.timestamp}" and schema.py is: import graphene from graphene_django import DjangoObjectType from temperature import models class Temperature(DjangoObjectType): class Meta: model = models.Temperature class Query(graphene.ObjectType): temperature = graphene.Field(Temperature, id=graphene.Int()) def resolve_temperature(self, info, **kwargs): id = kwargs.get("id") if id is not None: return models.Temperature.objects.get(pk=id) return None schema = graphene.Schema(query=Query) I want to make one query thatt returns the latest temperature added, like this: query { currentTemperature { timestamp value } } And another query that returns the min and max temperatures over a timespan, like this: query { temperatureStatistics(after: "2020-12-06T12:00:00+00:00", before: "2020-12-07T12:00:00+00:00") { min max } } I am having a lot of trouble finding documentation on how to accomplish this. I've looked at these graphql docs and this stackoverflow post. I've looked at other things as well but these are the only things that came close to helping. -
Using graphene-django to get "max" from DB
How do you implement an SQL "max" equivalent with graphql? The query should return the object from the database with the max value in a certain column. I have tried things like this from this stackoverflow post with no success: query { table_name(limit: 1, order_by: {time: desc}) { data time } } Where is tells me: { "errors": [ { "message": "Unknown argument \"limit\" on field \"table_name\" of type \"Query\".", "locations": [ { "line": 2, "column": 15 } ] }, { "message": "Unknown argument \"order_by\" on field \"table_name\" of type \"Query\".", "locations": [ { "line": 2, "column": 25 } ] } ] } I have also looked at these graphql docs that didn't tell me anything. Am I supposed to implement this in the schema.py file with a resolver? -

Showing derived value in ModelForm's generated HTML Django
I want to display a ModelForm field with a derived value (from a JS script) in its "row", something like this: /budgetsheet/ Expenses Value Percentage foo 30 0.3 Where the value in bold is the one derived. Here's how I imagined it in HTML: budgetsheet.html ... <head> ... <script> function get_val() { ... document.getElementById("derived_val").value = val } </script> </head> <body> ... <form> <p> {{ expenses }}</p> <p id="derived_val">&nbsp</p> <p>{{ percentage }}</p> ... </form> <body> Where the value in bold is the derived value not in the model fields: models.py class BudgetSheet(models.Model): ... foo = models.FloatField(...) def get_val(self): ... return val While typing this I figured the easy way out is to just add the derived value as a field in the model itself, but it'll still be a problem in terms of restricting it to be not editable (doesn't use input field or is in greyed out input field). It will also add a repetitive field in the model, too. Just wanted to see if there are other solutions to this that are better, or if this solution can get over these problems, and others that may come. Thanks! -
Pylance & Docker - Import "somepackage" could not be resolved
How to deal with this issue when the packages are all inside Docker? For now I have to install the packages locally to enable the intellisense. P.S. The packages DO WORK without installation on local machine. Just wonder how to enable the intellisense like file locating and autocomplete. I feel like I am working on Notepad++ instead of VS Code without intellisense. -

Django ModelForm non-required CharField giving errors
I have a ModelForm for a model that has a couple of files and with every file, a type description (what kind of file it is). This description field on the model has CHOICES. I have set these file uploads and description uploads as hidden fields on my form, and not required. Now the file upload is working, but the description is giving field errors, the placeholder in the dropdown is not a valid choice, it says. That's true, but since it is not required, I would like it to just be left out of the validation and I am stuck on how. My codes, shortened them up a bit to keep it concise. models.py class Dog(models.Model): FILE_TYPE_CHOICES = [ ('SB', 'Stamboom'), ('RB', 'Registratiebewijs'), ('SJP', 'SJP-diploma'), ('CDD', 'CDD-diploma'), ('WT', 'Workingtestdiploma'), ('MISC', 'Overig'), ] dog_id = models.UUIDField(unique=True, default=uuid.uuid4) file_1 = models.FileField(upload_to=user_directory_path, blank=True, validators=[extension_validator]) desc_1 = models.CharField(choices=FILE_TYPE_CHOICES, blank=True, max_length=5) forms.py (I excluded all these fields from the model-code above to keep it more clear, but this is to demonstrate that these fields are not required.

Check how many users answered keeps returning first value
I am trying to see how many users answered each option however it will give me the result of how many people answered the first option. Result object is where all answered are saved to. Do I need to make a loop in the html? Would this not work as you cant call Result in to html and filter it ? How would I go around doing this. I see the counter is staying to the first value and keeps looping for each option, but I am confused on a fix for this.

How to create a report showing revenue by product by year in Django?
Starting with this model: class LineItem(models.Model): created = models.DateTimeField(default=timezone.now) price = models.DecimalField(max_digits=8, decimal_places=2) product = models.CharField(max_length=15) From this, I want to create a report like this: Product. | 2020 | 2021 | 2022 ProdA | $10,000.00 | $9,500.00 | $3,200.00 ProdB | $110,000.00 | $98,000.00 | $35,300.00 ProdC | $119,500.00 | $54,000.00 | $25,300.00 To do this, I could use multiple queries to create a sequence of dictionaries, something like this: [ { "product": "ProdA", 2020: 10000.00, 2021: 9500.00, 2022: 3200.00, }, { "product": "ProdB", 2020: 110000.00, 2021: 98000.00, 2022: 35300.00, }, { "product": "ProdC", 2020: 119500.00, 2021: 54000.00, 2022: 25300.00, }, ] But I'm wondering if there's a better way (e.g, with one query). I'd appreciate any ideas. -

This is what I managed to do so far The Profile module: from django.db import models from django.contrib.auth.models import User from PIL import Image # Create your models here. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') bio = models.CharField(max_length=225, blank=True, default='') def __str__(self) -> str: return f"{self.user.username}'s Profile" def save(self): super().save() img = Image.open(self.image.path) if img.height > 300 or img.width > 300: img.thumbnail((300,300)) img.save(self.image.path) The Post module: from django.db import models from django.utils import timezone from django.contrib.auth.models import User from django.urls import reverse # Create your models here. class Post(models.Model): title = models.CharField(max_length=50) content = models.TextField() date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self) -> str: return self.title def get_absolute_url(self): return reverse('post-detail', kwargs={'pk':self.pk}) The view: class UserProfileView(ListView): model = Post template_name = 'blog/user_profile.html' context_object_name = 'posts' paginate_by = 5 def get_queryset(self): user = get_object_or_404(User, username=self.kwargs.get('username')) return Post.objects.filter(author=user).order_by('-date_posted') The blog/user_profile.html: {% extends 'blog/base.html' %} {% block title %}{{ view.kwargs.username }}'s … -

Django migration OperationalError: index [name] already exists
I hope someone can help me. I have three environments as part of my django development lifecycle, dev, uat and live. Django 3.2.6 with python 3.9.6. I'm trying to add a couple of fields to two of my models but I'm getting an error when I try to migrate the live database, the dev and uat database migrations worked fine. Here is the migration code, generated by makemigrations # Generated by Django 3.2.6 on 2022-01-26 21:33 from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ('tasks', '0015_activity_next'), ] operations = [ migrations.AddField( model_name='activity', name='delegated', field=models.BooleanField(default=False), ), migrations.AddField( model_name='activity', name='notified', field=models.BooleanField(default=False), ), migrations.AddField( model_name='adviser', name='digest', field=models.BooleanField(default=True, verbose_name='Send digest of assigned activities once per day?'), ), migrations.AddField( model_name='adviser', name='email', field=models.EmailField(default='i.pigney@tpio.co.uk', max_length=254), ), ] Nothing complex, just adding two fields to my Activity Model and another two fields to my Adviser model. I wasn't expecting any problems but... here is the error traceback: $python manage.py migrate ...
