Django ImageField Model: Get file path on upload_to callable
I have a Django admin field for uploading images, in my model I'm using a callable to get the FileField instance and Filename. My goal is to open the file the user is trying to upload and upload it to my Dropbox account through their API and return the URL where the image is saved. How do I get the full path for the file being uploaded? Here is what I currently have in my model: def upload_to_dropbox(self, filename): return DropboxStorage.store_file(self.image, filename) image = models.ImageField(upload_to=upload_to_dropbox) I tried using the ImageField's .url property but that returns my MEDIA_ROOT path, maybe I'm going about this the wrong way? -

Distinguish API call from own app/webapp vs server
I am using Django and we are planning on opening some of our API for 3rd party usage. Till now we have been using DRF along with session authentication for our Django Web App and DRF with JWT for our Android application. What I would like to know is whether the call is from our own app (webapp/android app) or from 3rd party apps (they can call from their own applications, which can be other webapps/phone apps). Is there any way this can be distinguished? We want to count the no.of 3rd party API call to our server. -

Django: Common/Reusable ModelAdmin Class
I have some functions like: has_delete_permission, has_add_permission, get_actions, formfield_for_foreignkey get_queryset Etc are the built-in ModelAdmin functions which I am using in almost all the ModelsAdmin's in my project. How to create a common/reusable class which include these functions and reuse in the other ModelAdmin classes? How to pass the reference of the Model or the ModelAdmin class to the common class? What should be the file structure to be maintained, in case this has to be used for many apps in a project. Some direction will be great help. Thanks. -

Status Code 405 while using google oauth2
I am using Django with Angular JS to access the Google Drive API. I am following this document from Google. The FLOW.step1_get_authorize_url() gives me the URL similar to the sample URL mentioned on the page. But the problem is that after return HttpResponseRedirect(authorize_url) the browser does not redirect to the authorize_url and gives the error as shown in the picture below (Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:8000' is therefore not allowed access. The response had HTTP status code 405). But if I copy pasted the URL, it works fine. The oauth2 function looks like this. def index(request): FLOW = flow_from_clientsecrets( settings.GOOGLE_OAUTH2_CLIENT_SECRETS_JSON, scope='https://www.googleapis.com/auth/drive', redirect_uri='http://127.0.0.1:8000/oauth2callback/' ) FLOW.params['access_type'] = 'offline' authorize_url = FLOW.step1_get_authorize_url() return HttpResponseRedirect(authorize_url) And here is the oauth2callback function. def auth_return(request): credential = FLOW.step2_exchange(request.GET) return HttpResponseRedirect("/mycustomurl") I used this to enable CORS in the Django Server Side.

Unsupported SRS when saving polygon in SRID=0 field
I'm trying to save a polygon with the default GeoDjango admin widget in an SRID 0 field. It gives an SRSException. I don't get what's wrong here, must there be a SRID for polygons to be saved? If so, is there a work around as I wish to save the coordinates of the polygon in raw simple CRS given in Leaflet (image overlay giving one pixel as one unit iirc) and using the default SRID changes the coordinates. What I'm trying to do is just a fake map with markers and polygons on it. -
filter company based on category
I was doing the project on Django to get into it more deeply. I have a problem in the model part. There is a model Company, Product, Category. Company is simply the introduction part. Product model is about what product a company has and its divided into category which is ManyToManyField. I have list all the categories in a page where if certain category is clicked then the list of companies that has product of that category should be filtered. But I don't know how to access it. Here is my model class Category(models.Model): name = models.CharField(max_length=50) slug = models.SlugField(max_length=50, unique=True) class Product(models.Model): name = models.CharField(max_length=200, unique=True, blank=False, null=False) company = models.ForeignKey('Company', related_name='products', blank=True, null=True, on_delete=models.SET_NULL) website = models.URLField(unique=True) slug = models.SlugField(unique=True) categories = models.ManyToManyField(Category, related_name='products') class Company(models.Model): name = models.CharField(max_length=200, unique=True, blank=False, null=False) slug = models.SlugField(unique=True) description = models.CharField(max_length=400) editor = models.ForeignKey(User, related_name='company') # product = models.ForeignKey(Product, related_name='company') -

Django template tags + using fabric.js
I've set up a reasonable Django site to test and play around with, but I'm having an awful time including fabric.js Ultimately I want to use fabric.js to take small images from a database and display them on a canvas, but I digress. The issue I'm having is that I cannot use a local png image within my html using fabric.js - I mean, fabric is included (because I can do very basic tricks with fabric, like create rectangles) However, the tutorial isn't clear on including local images. Here's my awful code: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>This is using render</title> {% load staticfiles %} <script scr="{% static "js/fabric.js" %}" type="text/javascript"></script> </head> <body> <script type="text/javascript"> var canvas = new fabric.Canvas('c'); canvas.setHeight(480); canvas.setWidth(640); var imgElement = fabric.Image.fromURL('../static/images/pitch.png', function(oImg) { canvas.add(oImg); }); var imgInstance = new fabric.Image(imgElement, { left: 100, top: 100, angle: 90, opacity: 0.85 }); canvas.add(imgInstance); </script> </body> </html> Probably doing something noobish, so apologies in advance. -
Image Downsizing and Upsizing in React Native like Instagram
Instagram changes image pixels when user posts it. I think Instagram resizes image on the Front-End. When we uploads image, how can we downsize or upsize the image in React Native? For instance (I've done little a bit of research), 1. 192 x 263 image -> 320 x 400 fixed image (upsized by width 320) 2. 250 x 220 image -> 320 x 282 fixed image 3. 183 x 276 image -> 320 x 400 fixed image 4. 2048 x 1152 image -> 1080 x 608 fixed image (downsized by width 1080) 5. 683 x 1024 image -> 683 x 853 fixed image (downsized by width 683) if the width of the image is greater than 1080 or lower than 320, it resizes the image. About my app, I'm using Django REST framework for Backend and React Native for Front-End. I'm sending image using http gzip compression. If I'm not wrong, apps downsize or upsize image from Front-End and send it to Backend. I think this way is the most efficient. -

gunicorn for chat bot
I have a chat bot written in python django and deployed with gunicorn. I started 12 workers on cpu with 2 cores. More than 12 I do not run, because the documentation is not recommended, but my cpu is loaded 7 percent maximum. Why I can not run 20 processes and more? Maybe I need run worker with multiple threads? I tried, but bot send many responce on one request. How can I start using all the resource of the processor? Maybe it's worth deploying the application to a different technology instead of gunicorn? Gunicorn i'm running so: nohup gunicorn --workers=12 --max-requests=5000 --bind 127.0.0.1:8000 exgirlbot.wsgi:application & Maybe i just need to set confugiratio? Thank you. -
Architectural design of an SQL & Document Database based Web Application
I am designing a web application with Django as the backend. Overview of the system is as follows Data is collected from user related to different entities. Example : Plant, Project, Machine, Test, etc. Configuration Blocks (consolidated, fully self contained, dated & versioned JSON files) are created by user by selecting different instances of above entities into a package. The config block is sent to an automated API server, which generates an API for the said block on the fly. I am trying to model the database structure the step 1. Known details Different classes of entities. Ex. Plant, Project, Machine, etc are known before hand and are fixed. Everything else is unknown. I don't know the data in the entities, the links between them, etc. I plan to user Postgres for a searchable relational data and a document database, CouchDB to handle the unknown data schema part. Envisaged Architecture I plan to have template tables for different entities, in a Postgres database, where, the administrator defines a set of templates for data required to be filled by the user. The template is a JSON document, with a protocol for defining different fields the user will fill out. My UI … -
Using For-Variables for Django Model coloumn
Dunno if its possible. Hopefully u guys knows what I try to do. I wanna do the model changes in a FOR loop cause the keys of the values have always the same name as the model coloums. My currently code: sites = DataModel.objects.all() for site in sites: d = self.getDataBySoup(soup) site.title = d['title'] site.text = d['text'] site.facebook = d['facebook'] site.twitter = d['twitter'] site.save() As you can see, the keys are always the same as the django coloumns. So I thought its maybe possible to do it with less code. What I tried (But not working): sites = DataModel.objects.all() for site in sites: d = self.getDataBySoup(soup) for key, value in d.items(): site.key = value site.save() I use Python 3.6
