Re: [Pydev-users] Setting up Eclipse pydev django development environment

[Fabio Z. <fa...@gm...>]

Hi Gary,

There are some ways you can setup things in your use case...

So, first, I'll explain a bit on the concepts related to then provide the
possible solutions:

Workspaces: Eclipse itself provides the concept of workspaces, so, each
workspace is completely independent from another (i.e.:
projects/configurations from one workspace are usually not visible to
another workspace).

Python Interpreter: PyDev can have multiple interpreters configured. You
can think of each interpreter as a virtualenv, where the configuration of
one is independent of the other (if you use virtualenvs, you should usually
configure an interpreter for each virtualenv).

Project: This is the place where your own source code should reside. Each
folder marked as a source folder will be set as an entry in the PYTHONPATH
(see http://www.pydev.org/manual_101_project_conf2.html).

As you said that you don't want things to be tied to system changes, you
should download a python install from python.org and keep it independent
from the computer installation (I must say I usually use miniconda to
create multiple python installations that are independent from the
system... you can see more at: http://conda.pydata.org/docs/).

As to how to map things internally, you can:

1. create a new workspace for each python/virtualenv/conda env you have
installed (and then all the projects/interpreters will be separate -- and
when launching Eclipse/PyDev, you should select with which one you want to
work -- if you want to work with multiple at the same time you have to
launch multiple instances... if you go that route, in preferences > general
> workspace you can set a workspace name to be shown in the title to help
you know which one you're working with).

2. Create a single workspace, configuring the multiple interpreters you
have in preferences > PyDev > Interpreters > Python interpreter and then,
for each project you have, go to the project properties (alt+enter with
project selected) > PyDev - Interpreter/Grammar and select which
interpreter that project should use.

To know how to deal with existing code, there's an entry in the FAQ related
to it:

Cheers,

Fabio
