Uvicorn running with Unicorn, how?
While reading the docs of running Uvicorn: Gunicorn is a mature, fully featured server and process manager. Uvicorn includes a Gunicorn worker class allowing you to run ASGI applications, with all of Uvicorn's performance benefits, while also giving you Gunicorn's fully-featured process management. Is doc wrong or i didn't understand correctly? from my understanding, Gunicorn has a master slave structure to allow Uvicon class(async sever) to run in separate worker classes using command: gunicorn example:app -w 4 -k uvicorn.workers.UvicornWorker why the doc says: Uvicorn includes a G unicorn worker class allowing you to run ASGI applications Someone could explain? thanks in advance! -
django raised 'function' object is not subscriptable but local python doesn't
I got a strange thing I can't handle and understand.

django-import-export: instance data not updated after save
I've got a model which allows imports via django-import-export. After the Event instances are imported I need to create related objects so I'm using after_save_instance to kick off celery tasks which reference the objects by ID. But in those tasks, when I retrieve the object from the database using the ID passed from the Resource class, I get old data. For example, the imported data changes the date value on an existing Event object and during after_save_instance the data is updated, but once the celery task retrieves the data it's different. Here's the stripped down resource class; class EventImportResource(resources.ModelResource): """ Admin importer for Events """ date = fields.Field( attribute='date', column_name='date', widget=LocalisedDateWidget( format=get_format('UK_DATE_INPUT_FORMATS') ) ) class Meta: model = Event fields = [ 'id', 'date', 'name', 'city', 'state', 'country', 'url' ] def after_save_instance(self, instance, using_transactions, dry_run): """ Override to add additional logic. Does nothing by default. """ if not dry_run: create_categories.delay(instance.id) # debugging at this point shows the new value # >>> instance.date # webapp_1 | datetime.date(2020, 10, 25) In the celery task I need to get the object from the database & perform some additional object creation etc. At this point, attributes on the instance are different to the instance … -

Sending files via AJAX; Request.FILES is empty?
As per title. I've created a function that would allow me to upload a file, parse it through AJAX to a Python function which then processes the file. I can either upload just an image file, or a zip file or a docx file et al. HTML: <input type="file" onchange="ProcessData(this)" id='theUpload' name='theUpload' accept="image/*,application/vnd.ms-excel, application/pdf,application/vnd.ms-word.document.macroEnabled.12,application/vnd.ms-word.template.macroEnabled.12,application/zip " style="display:none;" /> JavaScript ProcessData function(partial) function ProcessData(thisData){ thisCurrentAttachment = thisData; var formData = new FormData(); var filesizeLimit = 2097152; //2MB * 1024 * 1024 /* * Check if there is a file selected */ if (thisData.files.length==0) { document.getElementsByName("theUpload")[1].value = ""; return } underLimit=(thisData.files[0].size<=2097152); formData.append('theUpload', thisData.files[0], "Test"); if (underLimit) { $.ajax({ url: "{% url 'userProcessData' %}", type: "post", async: true, data: formData, contentType: false, processData: false, (....)

uwsgi + nginx... mistake after mistake in options
I think it's a second week started since I'm trying to start the server for Django app, first with Apache, second with gunicorn and now uwsgi + nginx... I'm very thankful for the help on my previous post... nginx with gunicorn and django on centos 7 It pushed me into the right direction... I don't know why, but most of guides for the django and server are incomplete and don't include settings tuning for the engines like gunicorn and nginx... there are some... and I tried to follow them, but end up with bunch of mistakes. I followed: http://michal.karzynski.pl/blog/2013/06/09/django-nginx-gunicorn-virtualenv-supervisor/ and https://youtu.be/DzXCHAuHf0I . Very good guides, but I ended up with the bunch of mistakes, which I'm trying to fix. Any help guys?

How to make a reusable "BooleanDate" field in Django?
For fields like "Accepts terms and conditions", "Authorizes newsletter sending" and so on, what I do is to use a DateTime field with null=True, but then only show a checkbox. If is null, the checkbox is unchecked. If it goes from unchecked to checked, the current date is stored. I know how to make it work, my question is: how should I approach the idea of making a custom model field that handles everything just by setting up this? newsletter_auth = BooleanDateTime("title") So then it works like I described in the admin panel, and provides the HTML representation for the front-end. Well now I realize that maybe that the right place for that is a custom widget, and in the model just set a normal DateTime field, and in the Form, specify the custom widget..? In any case, I'll appreciate recommendations to some tutorial, or some git with a clear example (I mean: if the example is too complex or is tangled amongst a thousand files' project it's probably going to be too much for me) Thanks a lot in advance! -
how to show maplotlib graph directly using django without showing it as an image?
I am trying to plot the graph using Django and matplotlib. So while plotting the graph on the Django template, I am converting matplotlib figure in png format and passing that png file to Django template. My requirement is as follows: I want to place the vertical lines on the graph, that vertical lines should be able to move left and right side horizontal on the graph. As we are passing the image on the Django template, it doesn’t seem possible to drag the vertical lines on the graph and to get the x value corresponding to it. Please suggest a way how we should be able to drag the lines and get its x axes value. Is there any direct way to plot matplotlib figure without passing it as an image? This is the code added in views.py: buffer = BytesIO() fig.savefig(buffer, format='png') buffer.seek(0) image_png = buffer.getvalue() buffer.close() graphic = base64.b64encode(image_png) graphic = graphic.decode('utf-8') Html code: <img src="data:image/png;base64,{{ graphic|safe }}"> I want to do similar to this on webpage. please refer image and reference link for more detail: Draggable lines select one another in Matplotlib I want to add red marker like this which should be drag-gable. -
