Trigger action after file upload into server(File exist on the server path)
I hit one question below, could you please help to give some suggestions? Appreciate. I want to get duration of a videofile upload by user, then update this “duration” into database after file uploaded. I find "post_save", but it looks this execute before the file upload(before this file exist in this server path, so if I use "post_save", I will hit the error that this file is not exist). Here is my step: 1.Create Voice Model include Field: videoFile(FileField) and the duration of this video(FloatField) 2.After user upload this file into server, I will run my algorithm in the file path and calculate this duration of this file(input: filepath and this filename; output: duration) 3.After get this duration of this file, I need to update this database immediately So my question is, how to execute my algo immediately after this file already uploaded into server? And then update database. -
Is this possible to invoke the method of QGroundControl from a Django(Python) web application?
I have a Django web application hosted on Ubuntu 18.04 and on the same machine I have installed the QGroundControl. In my Django Web Application there are two buttons (Take Off & Return to Land). Is this possible that when I press the Take Off button from my Web Application, it should invoke the Take Off method of QGroundControl? How can I connect the Django (Python) Web Application & QGroundControl? There will be some API or Web Service etc? Any idea? -

Running a group of tasks from another task celery
I'm having some trouble solving how to call tasks from another task in celery. Lets say I have the following tasks @shared_task def task_1(arg1, arg2): return @shared_task def task_2(arg1, arg2): return @shared task def task_3(arg1, arg2): return At the moment I'm calling tasks the following way. def task_caller(): task_1.apply_asyng(args=[arg1,arg2], queue='queue_1') task_2.apply_asyng(args=[arg1,arg2], queue='queue_1') task_3.apply_asyng(args=[arg1,arg2], queue='queue_2') I know i can check whether a task has finished or not with something along the lines of res = AsyncResult('task_id') res.ready() But, can this be done from inside another celery task? This way I can create custom tasks that call another tasks without stopping execution. I think about something like this @shared_task def super_task(arg1, arg2): task_1 = task_1.apply_async(args=[arg1,arg2], queue='queue_1') res_1 = AsyncResult(task_1.id) if res_1.ready(): # .... task2 and task3 But i'd have to check if each task has finished individually this way. Can tasks be grouped in some way and be called from another task? In my case task_2 does not need info from task_1 but I'd want to know if both tasks have finished. -

Why Is Django Creating Blank Text File With Project Name As Filename?
Python 3.8.2 Django 3.0.9 Ubuntu 20.04 I've been away from coding for a couple years & I went through the tutorial again to refresh my memory. After starting a new project, I wanted to rename the directory that contains asgi.py, settings.py, urls.py, & wsgi.py, so I can organize my project better. So I renamed that dir to config, & then changed the appropriate code in manage.py, asgi.py, settings.py, & wsgi.py, so it refers to "config.settings" & not "projectname.settings", since that dir is no longer called projectname. Now, when I run the server, it runs fine but it mysteriously creates a blank text file in the directory with manage.py, & the filename is the project name. Why is this happening? How do I stop it? -

How to test if it is a list or a value in a Django template?
In a template in Django I am importing a list of dicts and in one of the keys (tested) I can have either a single value or a list of values depending on the case. My context dict in the template looks something like this: context_dicts.append({'url': p.url, 'type_': p.type, 'error': error, 'tested': p.tested}) In the html template I want to if test the tested key to do something if it is a single value and something else if it's a list. So when looping through the dicts, if I use {% if value|length > 1% } it will give me the string size of the value when it's just a value and the length of the list when it's a list. How can I test the if to tell me if it's a "list of one value" or more? -

Django, how to group models by date?

Adding A Section To Admin Page
Ive changed certain parts of my admin page and played around extending the templates (so I have the file structure set up and working). I now want to go a bit further. I want to add a column next to the 'recent activity' column on the admin page which would list all the most recent django-notifications the admin has received. I am guessing I'd extend the base.html and add my notifications there. My first question is is this the best place to do this? The next, bigger thing is that I would need to modify the original views.py file to do this. Surely this isnt a good idea? Poking around in the Django Admin views.py sounds like a terrible idea and makes me think that this kind of thing shouldnt be done, however id still like to know for sure before I give up on it. I can find information on adding views to Django Admin, but nothing on adding content like this to the admin front page. Thank you. -
How to pass in variable into Django Form?
I've been reading lots of questions like this on stackoverflow but none seem to work. All I want to do is make a filtered form dropdown. I'm not sure how do go about doing it.

My form code looks like this: class AssignForm(ModelForm): class Meta(): model = Address fields = ['overseer','publisher', 'status'] def __init__(self, *args, **kwargs,): super(AssignForm, self).__init__(*args, **kwargs) self.fields['publisher'].queryset = Publisher.objects.filter(service_group=main) Here is my View: def assignment(request, pk_a): assign = Address.objects.get(id=pk_a) num = request.user.overseer.publisher_set.first() main = num.service_group.id print(main) I would like to use the variable: main inside my form dropdown so I can limit the dropdown relative to the overseer.

Storing and rewriting a constant variable (session key) in Django
Need advice. I have a program that sends a request for getting data to an external service. In order to receive data from this service, I must have a session key that is valid for 24 hours. A prerequisite for this service is to receive the key once a day. I created a constant in settings.py for key storage AUTHENTICATION_KEY = "" I created a task that makes a request for a key clock.py from apscheduler.schedulers.blocking import BlockingScheduler import os from django.conf import settings from clients.authentication import get_session_id # session key request function sched = BlockingScheduler() os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'my_project.settings') @sched.scheduled_job('cron', hour=0, minute=0, timezone='Europe/Kiev') def sess_id(): settings.AUTHENTICATION_KEY = get_session_id() return settings.AUTHENTICATION_KEY sched.start() Then I execute this program on Heroku. Of course, at first I performed this task at intervals and checked that the request for the key was successful, but when I call this key in another part of the program (where the request for data is received, session key comes with a request), the key variable (settings.AUTHENTICATION_KEY) is empty. As I understand it, rewriting a constant variable does not occur? Any suggestions on how to rewrite this variable globally? Perhaps there are other options how to get the key once a … -

Django shell_plus: How to access Jupyter notebook in Docker Container
I am trying to access a Jupyter Notebook created with the shell_plus command from django-extensions in a Docker container. docker-compose -f local.yml run --rm django python manage.py shell_plus --notebook My configuration is based on the answers of @RobM and @Mark Chackerian to this Stack Overflow question. I.e. I installed and configured a custom kernel and my Django apps config file has the constant NOTEBOOK_ARGUMENTS set to: NOTEBOOK_ARGUMENTS = [ '--ip', '0.0.0.0', '--port', '8888', '--allow-root', '--no-browser', ] I can see the container starting successfully in the logs: [I 12:58:54.877 NotebookApp] The Jupyter Notebook is running at: [I 12:58:54.877 NotebookApp] http://10d56bab37fc:8888/?token=b2678617ff4dcac7245d236b6302e57ba83a71cb6ea558c6 [I 12:58:54.877 NotebookApp] or http://127.0.0.1:8888/?token=b2678617ff4dcac7245d236b6302e57ba83a71cb6ea558c6 But I can't open the url. I have forwarded the port 8888 in my docker-compose, tried to use localhost instead of 127.0.0.1 and also tried to use the containers IP w/o success. It feels like I am missing the obvious here … Any help is appreciated.
