Currently File in form does not save
I have a formset with a group model and the group members form. I want to give the option of edit the group but when I save the group, the form is not valid because it have to upload the file field even when it says there is a currently file.

Django google app engine No such file or directory
I have django (2) with python 3.6 site in google cloud, the app is in app engine flex. (my first app :) My app has an upload page, where Iam asking the user upload a JSON file (that is never keep in the site), what i do is open it and generate another file from it I know that django depending on the size of the file it goes into memory but I was never able to use this functionality, so what I did in local env, was creating a folder that I called, temp_reports, so I created the files here, uploaded them into a bucket and then delete them, from temp_reports. So I was thinking, as the site is already in gcloud, if I can directly create this files into the bucket? or do i still need to generate them in the site and then upload them? Now if it is from my site I keep getting the following error: Exception Value: [Errno 2] No such file or directory: '/home/vmagent/app/temp_reports/file_516A3E1B80334372ADB440681BB5F030.xlsx I had in my app.yaml handlers: - url: /temp_reports static_dir: temp_reports Is there something I am missing? in order to use temp_reports?

Django Inlineformset forms primary keys error
So, I have this view on my project, it is for saving a formula of a product, in it I have two forms, the Formula, and the Lines of the formula (Formula_materia). The problem is that when I try to update the inline formset it throws a form validation error. It does not recognize the primary key, and says the field is empty (It is AutoField, and it is not rendered on the form). I searched all web, but couldn't find a answer that helps me.

Django Rest Framework Serializer add elements to Meta.fields

How would changing Django's cookie domain settings cause sporadic CSRF failures?
In my Django project, until recently I had left the settings SESSION_COOKIE_DOMAIN and CSRF_COOKIE_DOMAIN unset. Recently I changed them to .mydomain.com and since then I have been seeing sporadic CSRF failures on AJAX requests for certain users. The failure manifests as a 403 with CSRF token missing or incorrect. appearing in the logs. Asking users to clear cookies seems to resolve the issue, but I'm wondering how the settings change could have caused this and why it only seems to be happening for some users and not others. -

In Django Factory Boy, is it possible to mute a specific receiver (not all signals)?
In our Django project, we have a receiver function for post_save signals sent by the User model: @receiver(post_save, sender=User) def update_intercom_attributes(sender, instance, **kwargs): # if the user is not yet in the app, do not attempt to setup/update their Intercom profile. if instance.using_app: intercom.update_intercom_attributes(instance) This receiver calls an external API, and we'd like to disable it when generating test fixtures with factory_boy. As far as I can tell from https://factoryboy.readthedocs.io/en/latest/orms.html#disabling-signals, however, all one can do is mute all post_save signals, not a specific receiver. At the moment, the way we are going about this is by defining an IntercomMixin which every test case inherits from (in the first position in the inheritance chain): from unittest.mock import patch class IntercomMixin: @classmethod def setUpClass(cls): cls.patcher = patch('lucy_web.lib.intercom.update_intercom_attributes') cls.intercomMock = cls.patcher.start() super().setUpClass() @classmethod def tearDownClass(cls): super().tearDownClass() cls.patcher.stop() However, it is cumbersome and repetitive to add this mixin to every test case, and ideally, we'd like to build this patching functionality into the test factories themselves. Is there any way to do this in Factory Boy? (I had a look at the source code (https://github.com/FactoryBoy/factory_boy/blob/2d735767b7f3e1f9adfc3f14c28eeef7acbf6e5a/factory/django.py#L256) and it seems like the __enter__ method is setting signal.receivers = []; perhaps this could be modified so that … -
Django + gunicorn + nginx: 502 bad gateway but sometimes only?

Looking into the error/var/log/nginx/error.log, I only have errors like the following: upstream prematurely closed connection while reading response header from upstream I have no clue on what it implies: why would it be my Django install, if I have no issues when running on localhost for instance? also: sometimes all pages work and display just fine; sometimes the sames pages will throw a 502 error :( how could I know what's wrong with my gunicorn install, if the issue comes from there?

Image not saved to storage when loading with picasso
I have an application that syncs it's database with a Django server using the Django rest framework. I am able to upload images to the server. The problem is if an image is uploaded from another device or through the web app directly. When I try to re-sync using the "since" filter it shows that it is calling to GET the image (not made on the current device), but it is never saved. The only way that I found to fix it is to clear android cache and start an initial sync with the server. I am using Picasso to load images into a new Target: private void saveImage(final String url){ Picasso.get().load(url).into(new Target() { @Override public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) { try { String root = Environment.getExternalStorageDirectory().toString(); File directory = new File(root + "/instrumentImages"); if (!directory.exists()) { directory.mkdirs(); } String fileName = url.substring( url.lastIndexOf('/')+1, url.length() ); //String fileNameWithoutExtn = fileName.substring(0, fileName.lastIndexOf('.')); directory = new File(directory, fileName); FileOutputStream out = new FileOutputStream(directory); bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out); out.flush(); out.close(); } catch(Exception e){ Log.v("ActionSync", "Failed to save or load image."); } } I do not understand why it wouldn't be able to save the image if I am getting the URL.

Django queryset where a field values are in a list
I need to make a query that returns all rows where the field subject values exist in a list. I don't matter with sensitive case, but the values should be exact with the ones in the list.

I've been asked to implement as a group project a Django web app for a Scrum Board and I'm not familiar to Django nor Python. How can I do it? Do you have exhaustive guides? Which views/models I have to implement? Thanks in advance. -
Django using has_change_permission to determine owner
I want to restrict other user to change object instance other then owner user. For that I am using has_change_permission admin model function but It is not working. My model: class Book(models.Model): author = models.ForeignKey(User, related_name = 'book_author') ... In my admin.py class BookAdmin(admin.ModelAdmin): def has_change_permission(self, request, obj): if request.user.is_super_user(): return True elif request.user == obj.author: return True else: return False if obj is None: return False In my views.py class BookUpdate(generic.UpdateView): model = Book form_class = BookUpdateForm template_name = 'accounts/book_update.html' def get_object(self, *args, **kwargs): return Book.objects.get(id=self.kwargs.get('id')) In my urls: url(r'^update_book/(?P<id>[\w-]+)/$', views.BookUpdate.as_view(),name='update_book') Now when any one goes to this url pattern can edit book, but I need that only author can edit this book. Is has_change_permission right way to do so, or any other better way ? -
Python Requests Deployment
In on of my Django view´s I am making a request to another webserver via requests, this code works perfect when I run the code with the development server. It looks like that: import requests r = requests.post('http://www.example.org') return r.text But when I Deploy this an apaches www-data user is running it it throws this error: ConnectionError HTTPConnectionPool(host='www.example.com', port=80): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f23e917ba58>:Failed to establish a new connection:[Errno -2] Name or Service not known')) But I can run the code as root user from a seperate script on the Deployment server without a problem this is why i think it is a permission problem. But i have no Idea how to solve this. Thanks in advance! -
How to set up OrientDB PyOrient OGM with Django?
I am having difficulties in connecting Django with Orientdb PyOrient OGM. I have set the following connection strings and initialisation methods in my settings.py file in Django. # PYORIENT DB SETTINGS DJANGORIENT_SETTINGS = { 'host': 'localhost', 'port': '2480', 'username': 'xxxx', 'password': 'xxxxxxxxxx', 'name': 'authdb' } from pyorient.ogm import declarative Node = declarative.declarative_node() Relationship = declarative.declarative_relationship() but I am unable to connect to the database via my models.py file from pyorient.ogm.property import * from .settings import Node class Car(Node): registration = String(unique=True) colour = String() Any advice on how to connect the two technologies? -
have django setup to use /django/ path from http://localhost/django/
I have this WSGIScriptAlias /django/ /path/to/app in my Apache2 virtualhost config. I used django-admin startproject myapp to create the project. But when I go to http://localhost/django/ I get a 404 error via Django If I change the virtualhost config to just / and restart apache2. It works but I use that for other things hence the reason for virtualhost and /django/ sub-path. But it seems that Django is working just not from the correct path. Page not found (404) Request Method: GET Request URL: http://localhost/django/ Using the URLconf defined in djangoexamplecom.urls, Django tried these URL patterns, in this order: ^admin/ The empty path didn't match any of these. You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page. I am guessing when running django-admin startproject it expects the app to run at default URL i.e. http://localhost/ no sub-path? Do I need to edit url.py or settings.py to use /django/? -
