I want to create an executable file with various commands that run a project in django along with a virtual environment. The commands I want to run are:
d:
cd Python/projects
myvenv\Scripts\activate
cd web
python manage.py runserver
You can chain those commands like this in Windows machine:
Python\projects\myenv\Scripts\activate && python web\manage.py runserver

I am a student and my profesor needs me to install Django on PyCharm.
I made a big folder called PyCharmProjects and it includes like everything I have done in Python.
The problem is that I made a new folder inside this PyCharmProjects called Elementar, and I need to have the Django folders in there but it's not downloading.
I type in the PyCharm terminal django-admin manage.py startproject taskmanager1 (this is how my profesor needs me to name it)
After I run the code it says:
No Django settings specified.
Unknown command: 'manage.py'
Type 'django-admin help' for usage.
I also tried to install it through the MacOS terminal but I don't even have acces the folder named Elementar (cd: no such file or directory: Elementar) although it is created and it is seen in the PyCharm.
Manage.py its python file after you start your project, you cant call this file until this command:
django-admin startproject mysite
Then run:
python manage.py runserver
And if you want apps in your project run:
python manage.py startapp my_app
First of all, you can't create a project using manage.py because the manage.py file doesn't exist yet. It will be created automatically in the folder taskmanager1 if you run the command below.
You can create a project with the command
django-admin startproject taskmanager1
After that you can change the directory to the taskmanager1 folder with the cd taskmanager/ command.
When you changed the directory you can use the python manage.py commando for example if you want to run your migrations or creating an app.
python manage.py migrate
I downloaded a folder with multiple python files in the form of a Django project for a course and I am unable to run it. Usually, when you create a Django project it is created within the terminal with the line django-admin startproject web_project . and then python manage.py migrate is used and then the line python manage.py runserver to start a server.
How do I start a server to run my project?
When I use django-admin startproject web_project ., it creates a new project which I don't want. When I use python manage.py migrate or python manage.py runserver it says:
Command 'python' not found, did you mean:
command 'python3' from deb python3
command 'python' from deb python-is-python3
But even when I used python3 manage.py migrate or python3 manage.py runserver instead and it returned:
python3: can't open file 'manage.py': [Errno 2] No such file or directory
At first make sure you opened command prompt or terminal in right directory(in projects directory) when you are running the runserver command.
If you are on windows open the project folder(the folder that contains files like manage.py), then right click and press open PowerShell window here.
first of all I recommend creating a virtual environment using the following command
python3 -m venv .env
then activate it
source .env/bin/activate
"django-admin statproject" its for initalite a new project for running an excited Django app you should just install Django - if there is now "requirements.txt" file- , migrate and run.
pip install Django
python manage.py migrate
python manage.py runserver
I am having an issue via an apache Nearly Free Speech server (I have been following the NFS guide via this link: https://blog.nearlyfreespeech.net/2014/11/17/how-to-django-on-nearlyfreespeech-net/. I have created a run-django.sh file to properly run the application which also opens a virtualenv (I have named the folder 'venv'). These are the contents of my run-django.sh file:
#!/bin/sh
. venv/bin/activate
exec python3 manage.py runserver
On the current step of the guide I am attempting to run the run-django.sh as follows:
[questionanswer /home/protected]$ ls
question_answer run-django.sh venv
[questionanswer /home/protected]$ cd question_answer/
[questionanswer /home/protected/question_answer]$ ../run-django.sh
.: cannot open bin/activate: No such file or directory
How is this not detecting my directory of 'venv/bin/activate' ?
I'm trying to run a Python script I've uploaded as part of my AWS Elastic Beanstalk application from my development machine, but can't figure out how to. I believe I've located the script correctly, but when I attempt to run it under SSH, I get an import error.
For example, I have a Flask-Migrate migration script as part of my application (pretty much the same as the example in the documentation), but after successfully SSHing to my EB instance with
> eb ssh
and locating the script with
$ sudo find / -name migrate.py
when I run in the directory (/opt/python/current) where I located it with
$ python migrate.py db upgrade
at the SSH prompt I get
Traceback (most recent call last):
File "db_migrate.py", line 15, in <module>
from flask.ext.script import Manager
ImportError: No module named flask.ext.script
even though my requirements.txt (present along with the rest of my files in the same directory) has flask-script==2.0.5.
On Heroku I can accomplish all of this in two steps with
> heroku run bash
$ python migrate.py db upgrade
Is there equivalent functionality on AWS? How do I run a Python script that is part of an application I uploaded in an AWS SSH session? Perhaps I'm missing a step to set up the environment in which the code runs?
To migrate your database the best is to use container_commands, they are commands that will run every time you deploy your application. There is a good example in the EBS documentation (Step 6) :
container_commands:
01_syncdb:
command: "django-admin.py syncdb --noinput"
leader_only: true
The reason why you're getting an ImportError is because EBS installs your packages in a virtualenv. Before running arbitrary scripts in your application in SSH, first change to the directory containing your (latest) code with
cd /opt/python/current
and then activate the virtualenv
source /opt/python/run/venv/bin/activate
and set the environment variables (that your script probably expects)
source /opt/python/current/env
When I was developing and testing my project, I used to use virtualenvwrapper to manage the environment and run it:
workon myproject
python myproject.py
Of course, once I was in the right virtualenv, I was using the right version of Python, and other corresponding libraries for running my project.
Now, I want to use Supervisord to manage the same project as it is ready for deployment. The question is what is the proper way to tell Supervisord to activate the right virtualenv before executing the script? Do I need to write a separate bash script that does this, and call that script in the command field of Supervisord config file?
One way to use your virtualenv from the command line is to use the python executable located inside of your virtualenv.
for me i have my virtual envs in .virtualenvs directory. For example
/home/ubuntu/.virtualenvs/yourenv/bin/python
no need to workon
for a supervisor.conf managing a tornado app i do:
command=/home/ubuntu/.virtualenvs/myapp/bin/python /usr/share/nginx/www/myapp/application.py --port=%(process_num)s
Add your virtualenv/bin path to your supervisord.conf's environment:
[program:myproj-uwsgi]
process_name=myproj-uwsgi
command=/home/myuser/.virtualenvs/myproj/bin/uwsgi
--chdir /home/myuser/projects/myproj
-w myproj:app
environment=PATH="/home/myuser/.virtualenvs/myproj/bin:%(ENV_PATH)s"
user=myuser
group=myuser
killasgroup=true
startsecs=5
stopwaitsecs=10
First, run
$ workon myproject
$ dirname `which python`
/home/username/.virtualenvs/myproject/bin
Add the following
environment=PATH="/home/username/.virtualenvs/myproject/bin"
to the related supervisord.conf under [program:blabla] section.
