PTVS Django Data Base Migration - django

Im testing Python Tools For Visual Studio, I create a django project, make a SyncDB and install django admin with no problems, but now Im trying to make Data Base migration like: Django 1.7 Migrations. the point is that i cant figuer out how to do that. I serched in google and find this: How to run django database migrations with PTVS?. So the migration command is not wraped. I tried using Windows Command Prompt and install C:\Python34\;C:\Python34\Scripts; PATHS but when i type a django command like python manage.py runserver appears No module named 'django'. It seems that i am not pointing to my django project virtual env, but i dont know how to do that.
Execute command in my django app env path does not work neither.

Thanks a lot!

Before using of virtual env you should activate it. Execute env\activate or env\bin\activate. Not a windows guy so I'm not sure which path virtualenv uses on Windows :-)

You have to activate virtualenv. Go to env/Scripts directory and run activate.bat. Then go to your main project directory and try again python manage.py runserver. If you still see No module named 'django' make sure that django is installed in this environment try pip install django.

how do solve import error in django project

ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable i have activated the virtualenv on many but yet I can't run the server
When you install Django on your computer all things go fine but when you install a Virtual environment it gets separated from all things.
Just reinstall Django in the virtual environment:
pip install Django
and then just run the command for testing:
python manage.py runsever

ImportError: Couldn't import Django

I've already configured virtualenv in pycharm, when using the python manage.py command, this is error shown:
E:\video course\Python\code\web_worker\MxOnline>python manage.py runserver
Traceback (most recent call last):
File "manage.py", line 17, in <module>
"Couldn't import Django. Are you sure it's installed and "
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
How should I fix it, I've installed django.
I think the best way to use django is with virtualenv it's safe and you can install many apps in virtualenv which does not affect any outer space of the system
vitualenv uses the default version of python which is same as in your system
to install virtualenv
sudo pip install virtualenv
or for python3
sudo pip3 install virtualenv
and then in your dir
mkdir ~/newproject
cd ~/newproject
Now, create a virtual environment within the project directory by typing
virtualenv newenv
To install packages into the isolated environment, you must activate it by typing:
source newenv/bin/activate
now install here with
pip install django
You can verify the installation by typing:
django-admin --version
To leave your virtual environment, you need to issue the deactivate command from anywhere on the system:
deactivate
When you install Django on your computer all things go fine but when you install a Virtual environment it gets separated from all things. You will know it's importance when you will make a final project and deploy it to any cloud or hosting.
Just reinstall Django in the virtual environment and baam:
pip install Django
and then just run the command for testing:
python manage.py runsever
and you are all done.
You need to install Django, this error is giving because django is not installed.
pip install django
You need to use both commands:
pip install django and pip3 install django
that worked for me
Check that you have installed Django; by executing import django in python.
you mustn't see ModuleNotFoundError if everything's ok.
Check that you have installed virtualenv; by executing virtualenv --version.
you must see the version number if everything's ok.
Check that you have enabled virtualenv; there's got to be the name of your virtualenv in your command prompt starting line. enable it by
source bin/activate. also, remember to deactivate it every time your job is
finished with the virtualenv.
Check that your virtualenv includes django. a virtualenv by default
has no modules installed. you either have to install django in your
virtualenv (even if you have it in your machine already) or use
virtualenv --system-site-packages when creating a virtualenv to
include system site packages in the virtualenv.
Add django to your path. open python, import django, then run
django to see django's path. then add it to your ~/.bashrc (or
~/.zshrc if you're using zsh). more info in here
Install django-admin by running pip install django-admin
find your django parent dir path and add it to PYTHONPATH
In my case, my django parent dir path is /Library/Python/3.7/site-packages,add this line into ~/.bash_profile
export PYTHONPATH=/Library/Python/3.7/site-packages
else if you have PYTHONPATH already, just append it like this
export PYTHONPATH=${PYTHONPATH}:/Library/Python/3.7/site-packages
then
source ~/.bash_profile
I was having great difficulties with this but I have solved my issue. I am on Windows 10 using Vagrant ssh in my virtualenv environment, the box I have installed is ubuntu/xenial64, Django version 2.1, python==3.6.
When I was installing packages I was using pip3 but most importantly I was using sudo and the -H flag to install these packages. When I ran sudo pip3 freeze my packages would come up, but when I ran a plain pip3 freeze there would be no packages.
Then I tried the python3 manage.py startapp <YOUR APP NAME> and it did not work same error as you.
I finally thought to try sudo python3 manage.py startapp <YOUR APP NAME> it finally worked!
Hope this was help :)
I faced the same issue, and in my case it was because I had multiple python versions on my machine, in addition to the Anaconda ones.
In my case django didn't worked well with my anaconda python.
I knew that when I run import django on each python terminal for all versions I have.
As a summary here are the steps I made to get this solved:
Run the CMD as Admin
Create a project folder.
Create a new ENV for this new project INSIDE THE PROJECT Folder...
pip install virtualenv >> virtualenv new_env`
Activate it:
.\new_env\Scripts\activate`
After the env activation ⇒ Install Django:
python -m pip install Django
The python version you used here in step 5 will determine which python will to work with this installed Django.
If you are working on a machine where it doesn't have permissions to all the files and moreover you have two versions such as default 2.7 & latest 3.6 then while running the command use the python version with the command. If the latest python is installed with sudo then run the command with sudo.
exp:
sudo python3.6 manage.py runserver
after activating virtual env that error raises up on ubuntu.
and I solve this issue just by typing again :
pip3 install Django
inside the directory which is I want to create a new app.
You can use python3 to run file, if you don't want to use virtualenv.python3 manage.py runserver
To install python3 look at this page
Make sure you have Django installed by writing this command :
python -m django --version
if it's not installed you can install it by writing this command :
pip install django
I solved this problem in a completely different way.
Package installer = Conda (Miniconda)
List of available envs = base, djenv(Django environment created for keeping project related modules).
When I was using the command line to activate the djenv using conda activate djenv, the base environment was already activated. I did not notice that and when djenv was activated, (djenv) was being displayed at the beginning of the prompt on the command line. When i tired executing , python manage.py migrate, this happened.
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?
I deactivated the current environment, i.e conda deactivate. This deactivated djenv. Then, i deactivated the base environment.
After that, I again activated djenv. And the command worked like a charm!!
If someone is facing a similar issue, I hope you should consider trying this as well. Maybe it helps.
Instead of creating a new virtual environment, you just have to access to your initially created virtual environment when you started the project.
You just have to do the following in your command line:
1)pipenv shell to access the backend virtual environment that you have initially created.
2) Then, python manage.py runserver
Let me know if it works for you or not.
To create a virtual environment for your project, open a new command prompt, navigate to the folder where you want to create your project and then enter the following:
py -m venv project-name
This will create a folder called ‘project-name’ if it does not already exist and setup the virtual environment. To activate the environment, run:
project-name\Scripts\activate.bat**
The virtual environment will be activated and you’ll see “(project-name)” next to the command prompt to designate that. Each time you start a new command prompt, you’ll need to activate the environment again.
Install Django
Django can be installed easily using pip within your virtual environment.
In the command prompt, ensure your virtual environment is active, and execute the following command:
py -m pip install Django
In case you have virtual env activated, django installed, django-admin --version prints the valid version - check if there is no circular import in the file you are executing.
I faced the same problem when I was doing it on windows 10. The problem could be that the path is not defined for manage.py in the environment variables. I did the following steps and it worked out for me!
Go to Start menu and search for manage.py.
Right click on it and select "copy full path".
Go to your "My Computer" or "This PC".
Right click and select "Properties".
Select Advanced settings.
Select "Environment Variables."
In the lower window, find "Path", click on it and click edit.
Finally, click on "Add New".
Paste the copied path with CTRL-V.
Click OK and then restart you CMD with Administrator privileges.
I really hope it works!
Looks like you have not activated your virtualenv when using the runserver command.
Windows: <virtualenv dir>\Scripts\activate.bat
Linux: source <virtualenv dir>\bin\activate
You should see (name of virtualenv) as a prefix to your current directory:
(virtualenv) E:\video course\Python\code\web_worker\MxOnline>python manage.py runserver
windows :
(virtualenv dir)\Scripts\activate # this step to activate virtualenv
you should be in the dir of (project name)
python manage.py runserver
you need to go to the root directory
and run the below command
source bin/activate
Once the above command is executed, you will be able to create custom apps
I also face the same problem in windows 10 with anaconda
For me anaconda3\Scripts>activate
it's working good. What you have to do you just need to go to anaconda home
AppData\Local\Continuum\anaconda3\Scripts
and you need to open a cmd prompt and type activate.
It will activate the venv for you.
if you don't want to deactivate or activate the already installed venv just ensure you have set the pythonpath set
set pythonpath=C:\software\venv\include;C:\software\venv\lib;C:\software\venv\scripts;C:\software\venv\tcl;C:\software\venv\Lib\site-packages;
and then execute
"%pythonpath%" %venvpath%Scripts\mytestsite\manage.py runserver "%ipaddress%":8000
The problem is related to this error: Execution Policy Change
Start virtualenv by running the following command:
Command Line
C: \ Users \ Name \ yourdjangofilesname > myvenv \ Scripts \ activate
NOTE: On Windows 10, you may receive an error by Windows PowerShell that the implementation of these scenarios is disabled on this system. In this case, open another Windows PowerShell with the "Run as Administrator" option. After that, try typing the following commands before starting your virtual environment:
C:\WINDOWS\system32> set-executionpolicy remotesigned
Execution Policy Change:
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose you to the security risks described in the about_Execution_Policies help topic at http://go.microsoft.com/fwlink/?LinkID=135170.

After selection Y(es), close the Powershell admin window, and then go back to the Powershell Window(where you got the error) and run the command again.
> myenv\Scripts\activate and then python manage.py runserver 8085 ,
(8085 or any number if you want to change its default port to work on otherwise you dont need to point out anything. )
I had same problem, I installed all dependencies with root access :
In your case:
sudo pip install django
In my case, I had all dependencies in requirements.txt, So:
sudo pip3 install -r requirements.txt
Just sync your pipenv environment with:
pipenv sync
I had this problem with Django 3.
On manage.py detail the execute_from_command_line import.
You should have:
from django.core.management import execute_from_command_line
Instead of
from django import execute_from_command_line
I had the same problem and my solution was not posted here:
How I got the error
My error came whenever I was installation the requirements.txt file with pip (let's say from cloning a git repository).
Solution
I manually installed each of the modules in the requirements.txt + any other module needed for the installation of those modules (e.g: I got errors and some modules where missing to install other modules so I had to add them too).
If there is anyone who faced with the same problem when using virtual environment and running on MacOS, just try
sudo python manage.py startapp <project_name>
instead of
python manage.py startapp <project_name>
It will solve the problem suprisingly!
I had to install django using the virtual environment pip3 executable directly:
cd [virtual environment folder]/bin
sudo ./pip3 install django
If you already installed Django / configured virtualenv and you still having the error:
ImportError: Couldn't import Django. Are you sure it's installed and
available on your PYTHONPATH environment variable?
Try to run the command pipenv shell before start the server with py manage.py runserver

No module named 'chartit';

I am trying to use chartit in django and in its documentation it says add chartit to INSTALLED APPS in "settings.py".
When I try to do that, it gives this error:
ImportError: No module named 'chartit'
How do I import it?
Thank you.
PS-Sorry, it's a silly question.
You missed installing it with pip install django_chartit.
EDIT:
The error you described is thrown by python if a module is not found in the running environment. You need to make sure, that you've installed it in the environment that is used by your django.
Try typing pip list in the shell you usually use to kick your django with python manage.py runserver to figure out what is installed there.
If your django lives inside of a IDE like PyCharm - you need to check the project settings there for the environment used to launch django.
As you don't use virtualenv (which is highly recommended) you install your modules system wide. If you are on linux there might be python3 and python (which is python 2). If your pip belongs to python2 and you have installed django in python3 or vice versa this might be the issue.
from chartit import DataPool, Chart

Pinax on Webfaction - manage.py syncdb not finding virtualenv

(pinax09)[user#web213 social]$ python manage.py syncdb
Error: Can't import Pinax. Make sure you are in a virtual environment that has
Pinax installed or create one with pinax-boot.py.
I'm obviously in pinax09 virtualenv which has pinax installed hence I could create a social project with setup_project. However, once I run the syncdb it complains it can't import Pinax. What could be the problem?
Might be a problem with Python versions - I've had that on Webfaction before. Try just ./manage.py syncdb, without the python, which should run the correct version.

Is there a way to install Django 1.2 and 1.3 side by side?

I need to use Django 1.2 for one of my projects.
I also already have several projects running on Django 1.3 on the same server, and I need to keep them running.
Is there a way to only use 1.2 for a specific project?
Both sites run on Apache via mod_wsgi.
Consider installing Django inside a virtualenv. This will make the installation of python modules, including Django, completely independent of the rest of the system. This way, if you have multiple virtualenvs, you can have as many versions of Django installed (one per env).
To use a virtualenv, you shold edit your index.wsgi and add the following two lines before any other line that imports or references Django:
activate_this = '/path/to/env/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
This is assuming that you are not using different version of the python interpreter itself, which is possible using virtualenv, but would make things quite a bit more complicated.
Yes. Django is just a regular Python module living in your site-packages. So when you import django.something, the way Python decides which version to load is by walking down the Python path (import sys; print sys.path) in order and looking for a directory called django (with something.py or something/_init_.py inside). It loads the first one it finds. So the quickest method is to modify this Python path before starting your project, which can be conveniently done with an environment variable named PYTHONPATH.
So for your Django 1.2 project, install Django 1.2 in site-packages/django-1.2 and then:
# run Django 1.2 for old app that I don't have time to update
cd ~gaearon/src/old-django-project
env PYTHONPATH=/Library/Python/2.6/site-packages/django-1.2 ./manage.py runserver
For all other (Django 1.3) projects, simply install Django as normal, which makes it the default:
# all other projects use the system default Django 1.3
cd ~gaearon/src/current-django-project
./manage.py runserver
For production servers you won't use runserver, but the PYTHONPATH will work wherever you invoke Python (i.e. flup, or manage.py runfcgi). If invoked from mod_python there is an Apache configuration directive to modify the Python path (see mod_python documentation).
Or you could use virtualenv.
When I need to do stuff like this I have found that virtualenv combined with virtualenvwrapper helps a lot.
> mkvirtualenv django1.2
> cd django-1.2-dist-dir
> python setup.py install
> mkvirtualenv django1.3
> cd django-1.3-dist-dir
> python setup.py install
Now both Django versions are installed in their own virtual environments. To use a specific one do:
> workon django1.2
or
> workon django1.3
