TextCritical.net

h1. Setup And Install

Below are instructions for how to run your own instance of TextCritical.

h2. Install Prerequisites

To run TextCritical, you will need:

* "Django 1.8+":https://www.djangoproject.com/download/ 1.5.*":https://www.djangoproject.com/download/
* "Python 2.7":http://www.python.org/getit/
* "Grappelli":http://django-grappelli.readthedocs.org/en/latest/quickstart.html#installation
* A database (you can use SQLite to avoid extensive database setup)

You will need to install "Genshi":http://genshi.edgewall.org/wiki/Download and lxml.

h2. Install TextCritical App Code

Check out the source code from http://svn.lukemurphey.net/textcritical.com using a "Subversion client":http://en.wikipedia.org/wiki/Comparison_of_Subversion_clients.

Copy start_here_settings.py to settings.py (under the src directory). Update the settings.py file per your host.

h2. Configure and Initialize Database

Specify a database in settings.py unless you intend to use SQLite.

After configuring the database, run syncdb (from the src directory):

<pre>
python manage.py syncdb
</pre>

h2. Import Works

You will need to import the works into the library in order to have something for the site to provide access to. The easy way to do this is to use a prebuilt library. The more difficult way is to import the works yourself.

h3. Using Existing Library

To use an existing library, copy the library.sqlite file to the server. By default, it should be placed in the src directory.

h3. Importing Works

If you want to import works manually, then following the steps below.

First, initialize the library database.

<pre>
python manage.py syncdb --database=library
</pre>

Next, download the relevant works. The Perseus works can be obtained from "Perseus.tufts.edu":http://www.perseus.tufts.edu/hopper/opensource/download. Make sure to get the classics library. Decompress the archive.

Start the import process by running the following command, substituting "/Users/Luke/Perseus_Directory" with the location where you placed the files:

<pre>
python manage.py batch_import_perseus -d "/Users/Luke/Perseus_Directory"
</pre>

The import process may take a while (it takes about 70 minutes on a Core i7 with 8 GB of RAM). *Make sure to set DEBUG to False* before running the import. Otherwise, memory consumption will grow until the import completes.

h3. Indexing Works

You'll need to index the works for the search engine to work properly.

After importing the works, run the following:

<pre>
python manage.py make_search_indexes -c
</pre>

h2. Start Web Server

For production installs, you ought to use a production web-server like Apache. For development, you can use the built in Django web-server:

<pre>
python manage.py runserver 0.0.0.0:8080
</pre>

Alternatively, you can use the included CherryPy server which should be good enough for production use. To use it, start "run_server.py" after setting WEB_SERVER_ADDRESS and WEB_SERVER_PORT in settings.py; example below:

<pre>
<code class="python">
# The address and port to use when using the built-in web-server
WEB_SERVER_ADDRESS = '0.0.0.0' # Use '127.0.0.1' to serve content to localhost only
WEB_SERVER_PORT = 8080
</code>
</pre>

You can use lighttpd to serve as a reverse proxy to CherryPy. Below is a lighttpd config that will proxy to CherryPy or the Django web-server:

<pre>
# Define the location of text critical here:
var.textcriticalpath = "/Users/lmurphey/Documents/SP/Workspace/TextCritical.com"

# This is IP of the web-server:
var.proxyserver = "127.0.0.1"

# This is the port that Django server is running on:
var.proxyport = 8080

# This is the port to run the web-server on:
var.serverport = 8081

server.modules = ( "mod_proxy" )

$HTTP["url"] !~ "^/media/" {
proxy.server = ( "" =>
( (
"host" => var.proxyserver,
"port" => var.proxyport
) )
)
}

server.document-root = var.textcriticalpath + "/src"

server.port = var.serverport

mimetype.assign = (
".html" => "text/html",
".txt" => "text/plain",
".jpg" => "image/jpeg",
".png" => "image/png",
".css" => "text/css",
".js" => "application/javascript"
)
</pre>

h2. Upgrading

If you are upgrading an existing install from one of the older versions that supported Django 1.5, then you will need to do several things.

First, install Django 1.8:

<pre>
pip install Django==1.8.6
</pre>

Next, migrate the database:

<pre>
python manage.py migrate
</pre>

h2. Common Setup Issues

h3. Syncdb Fails Saying it couldn't create "django_content_type"

This has something to do with database routing. It can be solved by adding the following to the settings.py file and re-running syncdb:

<pre>
DATABASE_ROUTING = []
</pre>

Once syncdb succeeds, delete this line.

h3. Syncdb Fails When Creating Superuser

<pre>
You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yes

</pre>

You may need to set your locale by running the following before running syncdb:

<pre>
export LC_ALL="en_US.UTF-8"
</pre>

Delete the auth_users table and do another syncdb to try again.

h3. "__init__() keywords must be strings" when running Perseus Importer

This is caused by a "known bug in Python 2.6":http://bugs.python.org/issue2646 in which unicode arguments are not handled correctly. Upgrading to Python 2.7 resolves the issue.
