Configuring static files in OSQA development environment - python

I am using virtual machine with Ubuntu and Bitnami OSQA stack. It works fine. But if I try to debug it under PyCharm it doesn't. Static files become inaccessible, e.g.
/osqa/m/default/media/style/style.css
Error 404. As I understand, static files should be served automatically because the django.contrib.staticfiles module is used (but not sure, how to check this?).
Project settings in PyCharm are default, but after a very long investigations I replaced DJANGO_SETTINGS_MODULE value from settings onto OSQA.settings in order to fix empty MODULE_LIST error. I suppose the problem with static files can be fixed just as easy? I am novice in Python and Django

Django: unable to locate static files folder

I am trying to setup an AS2 server using the python package django-pyas2 (https://github.com/abhishek-ram/django-pyas2)
Everything has been working fine while I was using the runserver command, but when trying to host my web app using IIS(10), I've noticed that none of my static files get loaded when loading a page.
I've been on countless forums/documentations and I know that I need to setup my IIS to serve these files, but I haven't been able to answer a rather stupid question:
Where is the /static/ folder of django-pyas2 located ???
There is no such folder on the github page.
When using the runserver command, django somehow manages to find all the static files (.css, .js, .png) from the static folder, but I am still totally clueless to where that folder is actually stored.
I've been searching in these locations to no avail: (I'm using a virtual env on Windows Server 2016)
my own project
my venv's site-packages\django-pyas2 folder
in C:\Python37\Lib\site-packages\django-pyas2
in C:\User\AppData\Roaming\Python\Python37\Lib\site-packages\django-pyas2
I've also tried to use the command collectstatic, but I first need to know where the actual /static/ folder is stored.
I've double-checked, and the files are apparently stored locally and not on a CDN. This is driving me kind of nuts, and I could definetly use some help from someone!
A big thanks in advance ❤
EDIT:
my IIS wfastcgi configuration
my IIS advanced settings
I'm not sure about how IIS(10) works but this is usually the fix.
go to settings.py and add a path for your static files.
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')#new
Next on the console (command prompt/ terminal/shell) run
python manage.py collectstatic
This should work
OK, so I finally found the static folder I was looking for in this location:
<PYTHON_PATH>\Lib\site-packages\django\contrib\admin\static
I believe the django_pyas2 package is using some default js/css already included with Django, and I couldn't find it because it was burried in Django's files.
For those encountering the same problem, here are the steps I then took to make it work with IIS(10):
copy/pasted the static folder from the django package to my project's root
went to IIS manager, right clicked on my website > Add Application
for the application alias: "static", for the path: <path_to_static_folder>
/!\ IMPORTANT /!\ left clicked on newly created "static" application, went to Mapping Manager, and then deleted the associated FastCGIModule
Didn't have to do anything in settings.py, nor execute the collectstatic command.
Works fine after that!
Thanks for trying to help.

Is Appengine dispatch.yaml file affecting a specific module version?

I am starting to use modules in my python Google Appengine app.
I managed to test my configuration locally (on the dev server) and everything is working fine.
I want to test my changes on a side version online and didn't find a place that states whether the dispatch configuration will affect only my side version or my main serving version also (that's dangerous).
I know that cron.yaml is not a version specific file, how about dispatch.yaml?
Is it safe to deploy a side version with a dispatch file?
Thanks
From Configuration Files:
Optional application-level configuration files (dispatch.yaml,
cron.yaml, index.yaml, and queue.yaml) are included in the top
level app directory.
So no, you can't test a dispatch.yaml file change without affecting all versions of all your app's services/modules since it's an app-level configuration.
To be able to test app-level config file changes I'm using an entirely separate application as a staging environment.

Deploy Django project using wsgi and virtualenv on shared webhosting server without root access

I have a Django project which I would like to run on my shared webspace (1und1 Webspace) running on linux. I don't have root access and therefore can not edit apache's httpd.conf or install software system wide.
What I did so far:
installed squlite locally since it is not available on the server
installed Python 3.5.1 in ~/.localpython
installed virtualenv for my local python
created a virtual environment in ~/ve_tc_lb
installed Django and Pillow in my virtual environment
cloned my django project from git server
After these steps, I'm able to run python manage.py runserver in my project directory and it seems to be running (I can access the login screen using lynx on my local machine).
I read many postings on how to configure fastCGI environments, but since I'm using Django 1.9.1, I'm depening on wsgi. I saw a lot about configuring django for wsgi and virtualenv, but all examples required access to httpd.conf.
The shared web server is apache.
I can create a new directory in my home with a sample hello.py and it is working when I enter the url, but it is (of course) using the python provided by the server and not my local installation.
When I change the first line indicating which python version to use to my virtual environment (#!/path/to/home/ve_tc_lb/bin/python), it seems to use the correct version in the virtual environment. Since I'm using different systems for developing and deployment, I'm not sure whether it is a good idea to e.g. add such a line in my djangoproject/wsgi.py.
Update 2016-06-02
A few more things I tried:
I learned that I don't have access to the apache error logs
read a lot about mod_wsgi and django in various sources which I just want to share here in case someone needs them in the future:
modwsgi - IntegrationWithDjango.wiki
debug mod_wsgi installation (only applicable if you are root)
mod_wsgi configuration guide
I followed the wsgi test script installation here - but the wsgi-file is just displayed in my browser instead of beeing executed.
All in all it seems like my provider 1und1 did not install wsgi extensions (even though the support told me a week ago it would be installed)
Update 2016-06-12: I got a reply from support (after a week or so :-S ) confirming that they dont have mod_wsgi but wsgiref...
So I'm a bit stuck here - which steps should I do next?
I'll update the question regularly based on comments and remarks. Any help is appreciated.
Since your apache is shared, I don't expect you can change the httpd.conf but use instead your solution. My suggestion is:
If you have multiple servers you will deploy your project (e.g. testing, staging, production), then do the following steps for each deploy target.
In each server, create a true wsgi.py file which you will never put in versioning systems. Pretty much like you would do with a local_settings.py file. This file will be named wsgy.py since most likely you cannot edit the apache settings (since it is shared) and that name will be expected for your wsgi file.
The content for the file will be:
#!/path/to/your/virtualenv/python
from my_true_wsgi import *
Which will be different for each deploy server, but the difference will be, most likely, in the shebang line to locate the proper python interpreter.
You will have a file named my_true_wsgi to have it matching the import in the former code. That file will be in the versioning systems, unlike the wsgi.py file. The contents of such file is the usual contents of the wsgi.py on any regular django project, just that you are not using that name directly.
With this solution you can have several different wsgi files with no conflict on shebangs.
You'll have to use a webhost that supports Django. See https://code.djangoproject.com/wiki/DjangoFriendlyWebHosts. Personally, I've used WebFaction and was quite happy with it, their support was great and customer service very responsive.

Restarting Python to show changes

I am new to the python script. How do you restart a python script with Django through SSH?
I believe that you project is django based.
Django framework has a project directory, where static files are initially placed. And when you run your project for development purposes, django takes all static from the project static directory.
But for the production django deployment usually get runned command manage.py collectstatic to copy all static into another place. And sometimes there are another command - compress. To compress that static.
This is done to make webserver (apache or ngingx) respond static files without asking django process requests like "five me that static file" and gives ability to cache static files. And it speed-up all work.
So, if you serveer is setted up to take static files from static dir (looks like DOMAIN/public/static/main/ is the static dir) it will have no idea about changes in the project dir (looks like DOMAIN/project_book/main/static/main/ is a project dir).
But I agree with #Sause, looks like you have to be very carefull and have exact understanding of what you're doing with killing any process on the production server.
I think it could be useful for you to read Django documentation about static files too. https://docs.djangoproject.com/en/1.9/howto/static-files/
running pkill python in the ssh works.

What are the problems with loading CSS and JS from Django to IIS7?

I successfully deployed my Django site to IIS7 but I still have problems about how to configure IIS to serve the static files. I tried many many things from the internet but nothing seems to work. Everything is working fine on Django server (manage.py runserver) and with debug = True, but as soon as I turn off debug (debug = False) and open it on IIS, the bootstrap css and js are not loaded.
Do you have any ideas about why I'm experiencing this behavior? Perhaps you could point me to a step-by-step guide to help me?
Right click on your website in IIS7 manager and
add a virtual directory
name it with the same name of your folder you want IIS to handle. lets say static
add the path to your real static folder in your application mine was in myproject/static then ok
and here you go :)
If you are using django >= 1.3 and following the doc you are probably using the 'staticfiles' app.
First, you must configure your II7 to serve static files from the chosen path, by default URL: /static/ and PATH /staticfiles/ (I have no experience with II7 but the conf should be straightforward)
Then run ./manage.py collectstatic to move the static files into the correct path
and you should be done...
More info on production settings here.
You also need to insert a web.config file into the static directory for IIS to serve the files.
