Force browser to render with en locale
I am dealing with a browser rendering problem that renders decimal points using a comma, instead of a dot, in some languages. This breaks some javascript code. I tried setting lang attribute to en on the script/HTML tags and it appears not to work, and the browser still renders decimal points using a comma. My question is there a way to override the Accept-Language header, and set it to only use en? I am using Django. Otherwise dealing with this case directly in the code seems the only way. -
Execute delete() within save() in Django
I'm working on a Django/Wagtail project. I'm trying to build a very customized feature that requires an object to be deleted when hitting the Save button when certain conditions are met. I override the Save method: def save(self, *args, **kwargs): if condition: return super(ArticleTag, self).delete() else: return super(ArticleTag, self).save(*args, **kwargs) I know this looks very odd and completely anti-adviseable, but it is exactly the behavior I'm trying to achieve. Is there a better or "correct" way to do this? Are there other steps to exactly reproduce the behavior as if the user had hit Delete directly? -
ajax 500 error on adding a new field in django forms
I added a new file field in forms.py, no change in ajax- which is using form.serialize(),views- having no request.FILES attribute or any other change anywhere right now. models.py- class B(models.Model): filename = models.FileField(upload_to='files/') user = models.ForeignKey(User) class A(models.Model): ref = models.CharField(max_length=64, unique=True, blank=True) file = models.ManyToManyField(B, blank=True) forms.py class AForm(forms.ModelForm): file = forms.FileField(label='Select a file to upload', widget=forms.ClearableFileInput(attrs={'multiple': True}), required=False) class Meta: model = A fields = '__all__' and it is now giving a 500 (Internal Server Error) AJAX error, I am really not sure what the issue is since I have not done any changes. Please suggest- stuck on this for a long time now. -

Prevent form resubmission after post without redirect
Preface: I'm answering my own question, which i was stuck on for a while, but answered on another question thread. I have to start a new thread instead of commenting or voting on the answer that helped me, becasue I am not reputable (not enough StackOverflowreputation points). I guess I need to use StackOverflow more and suffer the catch 22 in the meantime. So I'd like to thank 'Eugen Konkov' for his solution here: https://stackoverflow.com/a/47247434/3588977 Sometimes Post/Redirect/Get is not possible. In my case the form is just a password used to decrypt content stored in database with a symettric AES cipher. The password is not to be stored anywhere and thrown away after decryption and render without any caching. It's simply not possible with Post/Redirect/Get. Even Django sessions are ot safe enough for my password/key or the decrypted content. With a simple javascript function to clear the history when the resultant render page is loaded, the user cannnot re-submit the form with back button and resubmit the previous post. -
Having two fields mandatory in a serializer togeather
I have a serializer which looks like this : > class MySerializer(serializers.Serializer): > lat = serializers.FloatField(required=False) > lng = serializers.FloatField(required=False) I want to make sure that if a request came with the 'lat' field, the 'lng' field will be mandatory and vice versa. I can do it with validate function but beleive there is a better way of doing that. -

Passing django url with tag to d3 js
I am trying to pass a url to d3.json and the url contains a variable. The url looks like this: url(r'my/url/(?P<tag>[0-9]{2})', some_view, name='my_url').

Incrementing a database counter concurrently
From what I read in the PostgreSQL documentation, it seems that queries like UPDATE accounts SET balance = balance + 100 WHERE account_id = 12345 are atomic and can be safely executed concurrently. Is this only the case when a single integer column is updated? In my Django app I have a query like this (generated by the ORM): UPDATE "mytable" SET "counter" = ("mytable"."counter" + 1), "owner" = NULL, "updated" = '2018-04-12T12:53:17.826257+00:00'::timestamptz WHERE "mytable"."id" = 27; args=(1, datetime.datetime(2018, 4, 12, 12, 53, 17, 826257, tzinfo=<UTC>), 27) which is executed concurrently by multiple background jobs. Will the counter be updated atomically in this case? I'm using the autocommit mode (Django default). -
Heroku Memory quota vastly exceeded in Django Project using SKLearn
I have deployed a Django application on Heroku with the goal of allowing trusted, known, internal users to upload a CSV file, click "Run", and behind the scenes, the Django app: loads a saved sklearn pipeline .pkl model (120 MB size, let's say) reads the user's CSV data using Pandas calls predict on the model using CSV data as input outputs file to S3 using Django Storages This works for small CSV files, but causes Memory quota vastly exceeded if user uploads a large CSV file... and it makes sense that larger CSV files are going to increase memory consumption. I'm not sure where to adjust. I'm wondering if someone out has experienced a similar scenario when deploying sklearn models and how they "solved" it? Ideas I have are: Identify memory leaks? No idea really even where to start on this one. Django DEBUG is set to False. Change my celery task to process the inputted file in chunks instead? Make a smaller SKLearn pipeline file somehow with joblib (I use compress=1 already)? My celery task looks like this: @shared_task def piparoo(id): instance = Upload.objects.get(id=id) model = joblib.load(instance.mlmodel.file.storage.open(instance.mlmodel.file.name)) data = pd.read_csv(instance.file) data['Predicted'] = model.predict(data) buffer = StringIO() data.to_csv(buffer, index=False) content … -

How to write a Django test that checks whether an error occurs on a page?
I'm currently debugging a pull request that has made a certain page error out: The view is subclassed from Django's generic UpdateView, and corresponds to the check-ins tab of a URL named 'family' in the dashboard app: url( r'^families/(?P<pk>[0-9]+)/' r'(?P<tab>case-management|scheduling|family-demographics|activation-payment|check-ins)$', views.FamilyUpdate.as_view(), name='family'), As a first step, I'd like to write a test which captures what I see, namely, an error occurring, so that after I fix it I can be sure it never happens again.

what does "=" mean in a django queryset filter on a ManyToManyField?
I'm not clear from the docs what an "=" filter condition means when used directly on a ManyToManyField. For example, if I have: class Publication(models.Model): title = models.CharField(max_length=30) class Article(models.Model): headline = models.CharField(max_length=100) publications = models.ManyToManyField(Publication) What does the .filter(publications=pub) do here: pub = Publication.objects.get(id=1) # or any other Publication Article.objects.filter(publications=pub) Will it select articles that have exactly/only this publication? Will it select articles that have at least this publication, among others? And what does the .filter(publications=pubs) mean here: pubs = Publication.objects.filter(id__in=[1,2]) # or any other subset query of Publication Article.objects.filter(publications=pubs) Will it select articles that have exactly/only this subset of publications? Will it select articles that have at least all of the publications, among others? Will it select articles that have at least one of these publications? -

Store data from API-url in a SQLite database with requests-library
Is it possible to fetch data from a API-url by using the python library "requests", and then store the data in SQLite database? The goal is to fetch dynamic data (not static data) with the API-url. Because I have fetched API-url just to use the data without storing the data in a database in other applications. If you could give me a quick example or any resources to how I should do it that would be really helpful. Have been searching several days for other solutions but none of them suits what I am trying to do. -
Django in docker: ajax POST is failing csrf
I'm attempting to set up my Django 1.11 application in Docker containers. Here's a summary of what I've done so far: Set up docker-compose.yml with an image for redis, django/uwsgi, and jwilder/nginx-proxy:alpine. docker-compose build runs with no issues. Set up my Django code so the client sends an X-CSRFToken custom header with each ajax POST request. This works fine when running Django with runserver. Set up my Django code to use redis as the session cache. Added the virtual hosts defined in docker-compose.yml to my /etc/hosts. Set up the virtual host name (dev.mysite.com) in Django's ALLOWED_HOSTS setting. At this point, I run my Docker setup using docker-compose up and I access my site in my browser using the virtual host (dev.mysite.com). It works for normal GET requests, but a subsequent ajax POST request fails on CSRF verification with the following CSRF failure reason: CSRF token missing or incorrect. The original response has a SET-COOKIE header with a csrf token that matches the X-CSRFToken header that the later ajax request contains. The ajax POST request also has the csrf cookie set, and that cookie also matches the SET-COOKIE header from the first request. At this point, I have no idea why … -

How to connect existing Django app with existing react app using webpack
So I have a Django project that acts as a backend REST server, and I would like to integrate that with an existing React project that makes AJAX calls to this REST server. Again, both of these projects already exist, I just want to connect them. Let's say the root of my Django project is DJANGOROOT and that is where manage.py is located. My Django project has a couple of Django apps that are part of the project. Let's say my Django project is called "mydjangoproj", the two Django apps are called "myapp1" and "myapp2" and the React project is called "myreactproj". Each of these two projects (the Django project with the two apps, and the React project) is stored in a separate GIT repo and to connect them on my server I have the following directory structure: DJANGOROOT/ DJANGOROOT/mydjangoproj DJANGOROOT/mydjangoproj/settings.py DJANGOROOT/mydjangoproj/urls.py DJANGOROOT/mydjangoproj/static/ DJANGOROOT/mydjangoproj/templates/ DJANGOROOT/myapp1 DJANGOROOT/myapp2 DJANGOROOT/myreactproj DJANGOROOT/myreactproj/package.json DJANGOROOT/myreactproj/src DJANGOROOT/myreactproj/src/index.js etc Note that the React app root folder is inside DJANGOROOT and is parallel to my django project and app folders. The React app uses an npm module called react-scripts (see https://github.com/facebook/create-react-app/blob/master/packages/react-scripts/template/README.md#npm-run-build) that has a build script that will build all the stuff in DJANGOROOT/myreactproj/src (staring with index.js) and will … -
