Re: Dreamhost Virtualenv Question

[Andre Terra]

A few more important things to note:

Your projects shouldn't live within your virtualenv directory. You can
create projects and virtualenvs with the same name (I often do), but it's
not mandatory.

So here's an example setup

~/virtual/djangotrunk
~/virtual/socialwebzone

~/projects/socialwebzone
~/projects/polls
~/projects/csvimporter

The projects listed can run in any of the virtual environments, although
their behavior would probably vary (for example, if you have django 1.1 in
~/virtual/socialwebzone).

What you *must do* is customize the PYTHONPATH variable upon activating an
environment. This can be done in many ways. For example, by manually editing
the activate script[1] in each virtualenv. Or, if using
virtualenvwrapper[2], by creating a postactivate hook script[3]. This is
where having the same name for a project and virtualenv can come in handy,
because then you can programatically add ~/projects/ to the
PYTHONPATH.


Cheers,
André Terra

The two most important things to concern yourself with regarding
starting developing with virtualenv (which is a must):

- source /path/to/venv/bin/activate: this command tells the shell
(bash, zsh, etc) to use the python interpreter located at
/path/to/venv/bin/python instead of the system python interpreter (eg.
/usr/bin/python)

- the pythonpath for your virtualenv is going to be
/path/to/venv/lib/python/site-packages. I usually maintain a separate
directory containing packages I need (either at ~/libraries for global
libraries, third-party apps, etc on my dev box) and
/path/to/venv/libraries on production boxes. Then I symlink python
modules that I need to the /path/to/venv/lib/python/site-packages
directory. Then they'll be on your PYTHONPATH.

The above applies to developing on a *nix box. If you are developing
on windows, stop what you are doing and install virtualbox and ubuntu
or go fully over to a *nix box. You'll appreciate it this.

Re: Dreamhost Virtualenv Question

[i...@webbricks.co.uk]

Jeremy,

there's a concept you need to understand to progress here. its on that
took me while to properly understand, but which i think is natural to
someone in a foss development role, which i hadn't previously been.

the python path is the all important config item. it defines where
python look sfor modules. its important because if you "pip install
django-zinnia -E envname" then you'll install the module to the site-
packages directory inside djangos modules. however its also (usually?
someone correct me if im wrong) equally valid to download the source,
read through the docco and then copy the module to the root of your
site ("envname/projectname"). you'll need to import the module
manually where you need to use it, but you'll have worked that out
already.

any help?

Re: Dreamhost Virtualenv Question

[Jeremy]

AHHH, that makes a little more sense.  I'm trying to install apps from
Github.  Things like Pinax, and different individual blogging apps so
that I can "plug" them into one Django project to give it multiple
bits of social functionality.  Obviously I'm having a lot of trouble
(some of it being that it sounds like I don't even know what I'm
saying).  I've tried to install these apps through PIP and other forms
on Dreamhost, but it keeps saying that I don't have permission.  The
way that I believed to get around this is to set up virtualenv on my
shared server space, and create the project inside of that, correct?
But if I do this, how can I view the project that I creating live?

Again, if this all sounds foolish, keep in mind I'm incredibly new to
all these concepts and my not understand them enough.  I've been
looking for someone locally to give me some Django lessons, but I keep
coming up dry.

Let me know if anyone can assist me.  Thanks guys.

I can only second Shawn here. FWIW, virtualenv is just a way to have

Please define "third party app" and "virtualenv project."

You can install a Python package in virtualenv using pip. "Viewing a
virtualenv project as a webpage" is nonsense.

I could guess at what you mean, but if you can clarify a bit it would help.

Dreamhost Virtualenv Question

[Jeremy]

Hello, I'm completely new to Django and the concept of virtualenv.
I'm trying to set up a web site and add in third party applications
such as the zinnia blogging app, but having some issues.  I believe
that I've set up the virtualenv correctly, but could someone walk me
through detailed steps as to install a third party app in the
virtualenv, then VIEW this virtualenv project as a webpage in a
browser?  Forgive me if I'm speaking non-sense, but I really need help
with this.  Thank you.
