## Give a try

On a Debian-based host - running at least Debian Stretch:

```
$ sudo apt install python3 virtualenv git make
$ git clone https://forge.april.org/siteweb/drupal2spip_lal
$ cd drupal2spip_lal/
$ make init

A configuration will be created interactively; uncomment
ENV=development

$ make test # optional
$ make serve
```

Then visit [http://127.0.0.1:8000/](http://127.0.0.1:8000/) in your web browser.

## Installation
### Requirements

On a Debian-based host - running at least Debian Stretch, you will need the
following packages:
- python3
- virtualenv
- make
- git (recommended for getting the source)
- python3-mysqldb (optional, in case of a MySQL / MariaDB database)
- python3-psycopg2 (optional, in case of a PostgreSQL database)

### Quick start

It assumes that you already have the application source code locally - the best
way is by cloning this repository - and that you are in this folder.

1.  Define your local configuration in a file named `config.env`, which can be
    copied from `config.env.example` and edited to suits your needs.

    Depending on your environment, you will have to create your database and the
    user at first.

2.  Run `make init`.

    Note that if there is no `config.env` file, it will be created interactively.

That's it! Your environment is now initialized with the application installed.
To update it, once the source code is checked out, simply run `make update`.

You can also check that your application is well configured by running
`make check`.

### Manual installation

If you don't want to use the `Makefile` facilities, here is what is done behind the scene.

It assumes that you have downloaded the last release of drupal2spip_lal,
extracted it and that you moved to that folder.

1.  Start by creating a new virtual environment under `./venv` and activate it:

        $ virtualenv --system-site-packages ./venv
        $ source ./venv/bin/activate

2.  Install the required Python packages depending on your environment:

        $ pip install -r requirements/production.txt
        ... or ...
        $ pip install -r requirements/development.txt

3.  Configure the application by setting the proper environment variables
    depending on your environment. You can use the `config.env.example` which
    give you the main variables with example values.

        $ cp config.env.example config.env
        $ nano config.env
        $ chmod go-rwx config.env

    Note that this `./config.env` file will be loaded by default when the
    application starts. If you don't want that, just move this file away or set
    the `READ_CONFIG_FILE` environment variable to `0`.

4.  Create the database tables - it assumes that you have created the database
    and set the proper configuration to use it:

        $ ./manage.py migrate

That's it! You should now be able to start the Django development server to
check that everything is working fine with:

    $ ./manage.py runserver

## Deployment

Here is an example deployment using NGINX - as the Web server - and uWSGI - as
the application server.

The uWSGI configuration doesn't require a special configuration, except that we
are using Python 3 and a virtual environment. Note that if you serve the
application on a sub-location, you will have to add `route-run = fixpathinfo:`
to your uWSGI configuration (from
[v2.0.11](https://uwsgi-docs.readthedocs.io/en/latest/Changelog-2.0.11.html#fixpathinfo-routing-action)).

In the `server` block of your NGINX configuration, add the following blocks and
set the path to your application instance and to the uWSGI socket:

```
location / {
    include uwsgi_params;
    uwsgi_pass unix:<uwsgi_socket_path>;
}
location /media {
    alias <app_instance_path>/var/media;
}
location /static {
    alias <app_instance_path>/var/static;
    # Optional: don't log access to assets
    access_log off;
}
location = /favicon.ico {
    alias <app_instance_path>/var/static/favicon/favicon.ico;
    # Optional: don't log access to the favicon
    access_log off;
}
```

## Structure
### Overview

All the application files - e.g. Django code including settings, templates and
statics - are located into `drupal2spip_lal/`.

Two environments are defined - either for requirements and settings:
- `development`: for local application development and testing. It uses a
  SQLite3 database and enable debugging by default, add some useful settings
  and applications for development purpose - i.e. the `django-debug-toolbar`.
- `production`: for production. It checks that configuration is set and
  correct, try to optimize performances and enforce some settings - i.e. HTTPS
  related ones.

### Local changes

You can override and extend statics and templates locally. This can be useful
if you have to change the logo for a specific instance for example. For that,
just put your files under the `local/static/` and `local/templates/` folders.

Regarding the statics, do not forget to collect them after that. Note also that
the `local/` folder is ignored by *git*.

### Variable content

All the variable content - e.g. user-uploaded media, collected statics - are
stored inside the `var/` folder. It is also ignored by *git* as it's specific
to each application installation.

So, you will have to configure your Web server to serve the `var/media/` and
`var/static/` folders, which should point to `/media/` and `/static/`,
respectively.

## Development

The easiest way to deploy a development environment is by using the `Makefile`.

Before running `make init`, ensure that you have either set `ENV=development`
in the `config.env` file or have this environment variable. Note that you can
still change this variable later and run `make init` again.

There is some additional rules when developing, which are mainly wrappers for
`manage.py`. You can list all of them by running `make help`. Here are the main ones:
- `make serve`: run a development server
- `make test`: test the whole application
- `make lint`: check the Python code syntax
