How do I read a request.FILES into DataSource in Geodjango
So, the goal is to create a webpage to load a .shp file into and get a summary of some calculations as a JsonResponse. I have prepared the calculations and everything and it works nicely when I add a manual path to the file in question. However, the goal is for someone else to be able to upload the data and get back the response so I can't hardcode my path. The overall approach: Read in a through forms.FileField() and request.FILES['file_name']. After this, I need to transfer this request.FILES object to DataSource in order to read it in. I would rather not upload the file on pc if possible but work directly from the memory. forms.py from django import forms from django.core.files.storage import FileSystemStorage class UploadFileForm(forms.Form): # title = forms.CharField(max_length=50) file = forms.FileField() views.py import json import os from django.http import Http404, HttpResponse, HttpResponseRedirect from django.shortcuts import render from django.template import loader from django.contrib import messages from django.views.generic import TemplateView from django.http import JsonResponse from django.conf import settings from .forms import UploadFileForm from . import models from django.shortcuts import redirect from gisapp.functions.functions import handle_uploaded_file, handle_uploaded_file_two from django.contrib.gis.gdal import DataSource from django.core.files.uploadedfile import UploadedFile, TemporaryUploadedFile import geopandas as gpd import fiona … -
How to Implement multiple kinds of users in Django?
I am new to Django so please bear with me if my questions seem too basic. So, I want to create a web app for a kind of a store in which I have three different kinds of users.

Using auth Groups, Profile models or anything else? Any help would be wonderful. If something is not very clear in the question, I can provide more details. Thanks. -

How to set a ManyToMany field to an existing object in a Django migration?
I'm trying to migrate a 1-to-many field to an existing many-to-many field. I'll explain. If I understood what was happening exactly, this question would be shorter. However, I'll try to give all the detail in hopes someone will spot the issue. For migrating a 1-to-many to a new many-to-many, I read this blog post (also like this question), which worked. To summarize: They started with a 1-to-many model (pizza has one topping): from django.db import models class Topping(models.Model): name = models.CharField(max_length=20) class Pizza(models.Model): name = models.CharField(max_length=20) topping = models.ForeignKey(Topping) and showed the migrations to get from one topping to multiple toppings per pizza. In the second of three migrations they add a topping to the new many-to-many toppings field in a forward method of a migration which looks like this: def forward(apps, schema_editor): Pizza = apps.get_model("pizza", "Pizza") for pizza in Pizza.objects.all(): pizza.toppings.add(pizza.topping) However, now I'm trying to migrate a different model to use the existing toppings. add isn't right, because I don't want to create new relationships, I want to use existing ones. This is stretching the pizza example, but suppose I have a note for some pizzas about their topping (I dunno, calories?). That worked when there was one … -

Using custom models.py module name with custom user account app in Django
I have a custom user account model which I use in the settings like so; AUTH_USER_MODEL = 'user_account.UserAccount' This obviously refers to user_account.models.UserAccount model class. Though, I would like to rename the models.py module to user_account_models.py, in which case django naturally complains about user_account.UserAccount not being exist. I've checked the doc, and models are stated in app.ModelName format, nothing in between to refer to where the model is "since django assumes they will always be in models.py in every app" I assume. Is there a way to make django use custom names for models.py module (or any module for that matter) for a particular app (since every app will have it's own distinctive name with the app name as prefix)? -

Bulk Create catch exceptions in Django
I'm trying to create 30,000 objects in Django but need the error response for each object.
