Using django-twilio package forgery protection is creating forbidden 403 error
I am using django-twilio package for forgery protection django-twilio forgery protection docs I have a django texting app that is being used to both send automated messages directly through my cellphone messenger and also from my website while logged in. When DJANGO_TWILIO_FORGERY_PROTECTION = False, both platforms using my django texting app work. When DJANGO_TWILIO_FORGERY_PROTECTION = True, only cellphone messenger works, and website gets 403 Forbidden. How can this be fixed while maintaining as much security as possible and keeping the same app as functional for both cellphone messenger and website.

One model to have children and parents objects in Django
I am trying to create a tool that replicates the use of an EXCEL sheet. The ideal use is to have: -Sections (Parent objects) -Fields to be filled (Children objects of given section) Ideally, I am looking for this to be in one Model class called Car specifications (for example). A typical object of this would have a one-to-one relationship with model Car. Each Car Specification object would have Sections, e.g Car Headlights, and there are a number of fields to be filled for Car Headlights section (e.g type, size, manufacturer..etc). It can be text, date, file.. or even another model object(s). My question is: What would be the best way to approach this? I apologies if my terminology usage is wrong, I'm still a python-django beginner :) Thank you in advance! An example Excel sheet might look like this: 1.0 Car Headlights 1.1 Headlight type: 1.2 Headlight shape: 1.3 Compatible models: this is a list/one to multi relationship 2.0 Windows# 2.1 Glass type: 2.2 Country of origin: 2.3 Tint level: And so on -
Django model for table with foreign keys to multiple tables in one column
I have inherited a table that has data that has foreign keys to different tables that share a column. The dedupe_sig column is a virtual column with a uniqueness constraint where the place names are sorted. It's used to ensure that you don't try to store both Toledo S Ann Arbor and Ann Arbor N Toledo: the table with the directions says that S and N are opposites. location_type place1 relation place2 dedupe_sig --------------- ------------- ---------- -------------- ---------------------------------- city Youngstown SE Cleveland city Cleveland Youngstown neighborhood Campus S Clintonville neighborhood Campus Clintonville region Midwest NW The South region Midwest The South city Cincinnatti NE Lexington city Cincinnatti Lexington state Ohio E Indiana state Indiana Ohio state Illinois S Wisconsin state Illinois Wisconsin What I'd like to know is if there's a sane way for me to add this table to my Django models? It seems like it should be a ManyToManyField, but I'm not sure how to handle implementing it without changing the schemata (either by making separate join tables for the different location types or by moving all the location data into a single table that links to itself for arbitrary nesting hierarchy). -
Boolean condition doesn't work in django template
i'm trying to add in my template a simple "s" to a string depending on the number of answers : The house contains {{nb_results2}} {% if nb_results2 >= 2 %}rooms{% else %}room{% endif %} {{nb_results2}} appears in my page (it's a str of a count), but whatever the number is, only "room" is displayed. Is it something related to the string nature of my nb_results variable ? Thanks for your help ! -
How to delete a kwargs argument if it is empty?
I am working with arguments, variables that I go through GET and I receive in my view to do my queryset, the problem is, if I receive an empty argument does not work, I explain more with code. My url example: http://127.0.0.1:8000/my_view/?val1=xd&val2=lol&sox= My view.py val1 = request.GET.get('val1', None) val2 = request.GET.get('val2', None) foo = request.GET.get('lol', None) filters = { 'code_field': val1, 'tiempo_field__lte': val2, 'code_id__exact': foo, } my_query = Babies.object.filter(**filters) In this example sox is empty, that's why it doesn't work for me I think, what would be the elegant way if an argument comes empty is not taken in the query. -
Image getting saved twice in media folder django Imagefiled PIL
I am trying to resize the image in form's save method that extends modelform. I open the image and resize it then saves it using PIL in the save method of form. But in the media folder that has all the save images it saves two images one that is resized and other that was original. I guess that must be because of the form's save getting called after PIL's save has been called. Is there a way to save only the resized image. def save(self): mymodel = super().save(commit=False) checkpath = mymodel.picture1 image = Image.open(checkpath) image = image.resize((33,33), Image.ANTIALIAS) image.save(checkpath.path) mymodel.save() It saves two images in media folder first is a.jpg that is the orignal name of the image and other is akjdsfj.jpg random name. The second must have been formed when model's save got called. Is there a way to stop this behaviour and save only one image that is resized. -

How can I block calls from unknown domains/IP to my REST API?
I want to block calls to my Django REST API (www.backend_django.com) from unknown origins, for example, I have a website under the domain "www.example.com" I want to allow only to this site to be able to do request to my API. In order to do this, I have configured Django-Cors-Headers in the following way: DEBUG = False ALLOWED_HOSTS = ["www.backend_django.com", "backend_django.com"] CORS_ORIGIN_ALLOW_ALL = False CORS_ORIGIN_WHITELIST = ( 'https://backend_django.com', 'https://www.backend_django.com', 'https://example.com', 'https://www.example.com', ) CSRF_TRUSTED_ORIGINS = [ 'backend_django.com', 'example.com'] In order to test it, I have done a call from Postman using my computer and have successfully done a request still to the API. Did I set up something bad in the settings? How can I archive this? -
Github Oauth Web Flow CORS
I have a project that consist of a Django rest server back-end and a vue js front end. I am trying to authenticate with GitHub using their oauth2 web flow. So far I seem to get blocked by CORS or Github returns not found. I have tried a different couple approaches but so far have had the best results with the following: In my front end I authenticate with GitHub which returns an temporary code. I then post the code to my back-end which then makes a request to get an access token from GitHub which returns a CORS error. I am assuming this is because the front-end and back-end servers are on different domains which is causing problems. The interesting thing to me is if I copy the code and then make the call in postman it works fine and returns the access code. Why does it work in postman which isnt on the same domain and what I am doing wrong? Some points that maybe of interest: I have Django CORS installed my GitHub callback points to my front-end I tried making all the calls from the front end but still get blocked by CORS The CORS error … -

Is there documentation for class option for Django fieldset?
In the Django admin docs, it mentions fieldsets. The example they specify a class collapse. This class will make the fieldset collapsible in the admin page. I found 2 other examples of a classes one could use. I found looking for a list of other classes I can use is wide or extrapretty. Other than these examples I have not been able to find anything else about the class option in the fieldset.
