django-amazon-price-monitor
===========================

Monitors prices of Amazon products via Product Advertising API.

Basic structure
---------------

This is a reusable Django app that can be plugged into your project. It
consists basically of this parts:

-  Models
-  Frontend components
-  Angular Frontend API
-  Amazon API component

Models
~~~~~~

-  Product

   -  representation of an Amazon product

-  Price

   -  representation of a price of an Amazon product at a specific time

-  Subscription

   -  subscribe to a product at a specific price with an email
      notification

Frontend components
~~~~~~~~~~~~~~~~~~~

The frontend displays all subscribed products with additional
information and some graphs for price history.

The features are the following:

-  list products
-  show product details
-  show product price graphs
-  add subscriptions
-  adjust subscription price value
-  delete subscriptions

Angular Frontend API
~~~~~~~~~~~~~~~~~~~~

Simply the API consumed by AngularJS, based on Django REST Framework.

Amazon API component
~~~~~~~~~~~~~~~~~~~~

Fetches product information from Amazon Product Advertising API through
several tasks powered by Celery and weaves the data into the models.

~~~~~~~~~~~~~

+--------+-----+------------+-----+
| Python | 3.3 | 3.4        | 3.5 |
+========+=====+============+=====+
| Django | 1.8 | 1.8 or 1.9 | 1.9 |
+--------+-----+------------+-----+

For additional used packages see `setup.py <https://github.com/ponyriders/django-amazon-price-monitor/blob/master/setup.py#L23>`__.

Included angular libraries
~~~~~~~~~~~~~~~~~~~~~~~~~~

-  angular-django-rest-resource (`commit:
   81d752b363668d674201c09d7a2ce6f418a44f13 <https://github.com/blacklocus/angular-django-rest-resource/tree/81d752b363668d674201c09d7a2ce6f418a44f13>`__)

Basic setup
~~~~~~~~~~~

Add the following apps to *INSTALLED\_APPS*:

::

    INSTALLED_APPS = (
        ...
        'price_monitor',
        'price_monitor.product_advertising_api',
        'rest_framework',
    )

Then migrate:

::

    python manage.py migrate

Adjust the settings appropiately, `see next chapter <#settings>`__.

Include the url configuration.

Setup celery - you'll need the beat and a worker.

Settings
~~~~~~~~

*The values of the following displayed settings are their default
values. If the value is '...' then there is no default value.*

Must have settings
^^^^^^^^^^^^^^^^^^

The following settings are absolutely necessary to the price monitor
running, please set them:

Celery
''''''

You need to have a broker and a result backend set.

::

    BROKER_URL = ...
    CELERY_RESULT_BACKEND = ...

    # some additional settings
    CELERY_ACCEPT_CONTENT = ['pickle', 'json']
    CELERY_CHORD_PROPAGATES = True

Rest-Framework
''''''''''''''

We use Rest-Framework for Angular frontend:

::

    REST_FRAMEWORK = {
        'PAGINATE_BY': 50,
        'PAGINATE_BY_PARAM': 'page_size',
        'MAX_PAGINATE_BY': 100,
    }

Site URL
''''''''
Specify the base URL under which your site will be available. Defaults to: *http://localhost:8000*
Necessary for creating links to the site within the notification emails.

::

    # base url to the site
    PRICE_MONITOR_BASE_URL = 'https://....'

AWS and Product Advertising API credentials
'''''''''''''''''''''''''''''''''''''''''''

::

    # your Amazon Web Services access key id
    PRICE_MONITOR_AWS_ACCESS_KEY_ID = '...'

    # your Amazon Web Services secret access key
    PRICE_MONITOR_AWS_SECRET_ACCESS_KEY = '...'

    # the region endpoint you want to use.
    # Typically the country you'll run the price monitor in.
    # possible values: CA, CN, DE, ES, FR, IT, JP, UK, US
    PRICE_MONITOR_AMAZON_PRODUCT_API_REGION = '...'

    # the assoc tag of the Amazon Product Advertising API
    PRICE_MONITOR_AMAZON_PRODUCT_API_ASSOC_TAG = '...'

Amazon associates
'''''''''''''''''
As the links to Amazon will be affiliate links with your Amazon associate tag (see above), you have to set your name for the disclaimer
(see `https://partnernet.amazon.de/gp/associates/agreement <https://partnernet.amazon.de/gp/associates/agreement>`__).

::

    # name of you/your site
    PRICE_MONITOR_AMAZON_ASSOCIATE_NAME = 'name/sitename'
    # Amazon site being used, choose from on of the following
        'Amazon.co.uk'
        'Local.Amazon.co.uk'
        'Amazon.de'
        'de.BuyVIP.com'
        'Amazon.fr'
        'Amazon.it'
        'it.BuyVIP.com'
        'Amazon.es'
        'es.BuyVIP.com'
    PRICE_MONITOR_AMAZON_ASSOCIATE_SITE = '<ONE FROM ABOVE>'


Images protocol and domain
''''''''''''''''''''''''''

::

    # if to use the HTTPS URLs for Amazon images.
    # if you're running the monitor on SSL, set this to True
    # INFO:
    #  Product images are served directly from Amazon.
    #  This is a restriction when using the Amazon Product Advertising API
    PRICE_MONITOR_IMAGES_USE_SSL = True

    # domain to use for image serving.
    # typically analog to the api region following the URL pattern
    #  https://images-<REGION>.ssl-images-amazon.com
    PRICE_MONITOR_AMAZON_SSL_IMAGE_DOMAIN = 'https://images-eu.ssl-images-amazon.com'

Optional settings
^^^^^^^^^^^^^^^^^

The following settings can be adjusted but come with reasonable default
values.

Product synchronization
'''''''''''''''''''''''

::

    # time after which products shall be refreshed
    # Amazon only allows caching up to 24 hours, so the maximum value is 1440!
    PRICE_MONITOR_AMAZON_PRODUCT_REFRESH_THRESHOLD_MINUTES = 720  # 12 hours

Notifications
'''''''''''''

To be able to send out the notification emails, set up a proper email
backend (see `Django
documentation <https://docs.djangoproject.com/en/1.5/topics/email/#topic-email-backends>`__).

::

    # time after which to notify the user again about a price limit hit (in minutes)
    PRICE_MONITOR_SUBSCRIPTION_RENOTIFICATION_MINUTES = 10080  # 7 days

    # sender address of the notification email
    PRICE_MONITOR_EMAIL_SENDER = 'noreply@localhost'

    # currency name to use on notifications
    PRICE_MONITOR_DEFAULT_CURRENCY = 'EUR'

    # subject and body of the notification emails
    gettext = lambda x: x
    PRICE_MONITOR_I18N_EMAIL_NOTIFICATION_SUBJECT = gettext(
        'Price limit for %(product)s reached'
    )
    PRICE_MONITOR_I18N_EMAIL_NOTIFICATION_BODY = gettext(
        'The price limit of %(price_limit)0.2f %(currency)s has been reached for the '
        'article "%(product_title)s" - the current price is %(price)0.2f %(currency)s.'
        '\n\nPlease support our platform by using this '
        'link for buying: %(link)s\n\n\nRegards,\nThe Team'
    )

    # name of the site in notifications
    PRICE_MONITOR_SITENAME = 'Price Monitor'

Caching
'''''''

::

    # key of cache (according to project config) to use for graphs
    # None disables caching.
    PRICE_MONITOR_GRAPH_CACHE_NAME = None

    # prefix for cache key used for graphs
    PRICE_MONITOR_GRAPH_CACHE_KEY_PREFIX = 'graph_'

Celery settings
~~~~~~~~~~~~~~~

To be able to run the required Celery tasks, Celery itself has to be set
up. Please see the `Celery
Documentation <http://docs.celeryproject.org/en/latest/index.html>`__
about how to setup the whole thing. You'll need a broker and a result
backend configured.

Development setup with Docker
-----------------------------
The package comes with an easy to use Docker setup - you just need ``docker`` and ``docker-compose``.
The setup is nearly similar to the one of `treasury <https://github.com/dArignac/treasury>`__ ( a project by `darignac <https://github.com/dArignac>`__), you
can read the `documentation <http://treasury.readthedocs.org/en/latest/installation/docker.html>`__ there to get a better insight.

Structure
~~~~~~~~~
There are 5 containers:

====== =======================================================================
db     Postgres database
------ -----------------------------------------------------------------------
redis  Celery broker
------ -----------------------------------------------------------------------
web    a django project containing the ``django-amazon-price-monitor`` package
------ -----------------------------------------------------------------------
celery the celery for the django project
------ -----------------------------------------------------------------------
data   container for mounted volumes
====== =======================================================================

The ``web`` and ``celery`` containers are using a docker image being set up under ``docker/web``.

Image: base
^^^^^^^^^^^
Basic image with all necessary system packages and pre-installed ``lxml`` and ``psycopg2``.
The image can be found on `Docker Hub <https://hub.docker.com/r/pricemonitor/base/>`__.

Image: web
^^^^^^^^^^
It comes with a Django project with login/logout view, that can be found under ``docker/web/project``.
The image derives from ``pricemonitor/base`` from above.

The directory structure within the container is the following (base dir: ``/srv/``):
::

	root:/srv tree
	├── logs		[log files]
	├── media		[media files]
	├── project		[the django project]
	├── static		[static files]
	└── pricemonitor	[the pricemonitor package]

Starts via the start script ``docker/web/web_run.sh`` that does migrations and the starts the ``runserver``.

Image: celery
^^^^^^^^^^^^^
Basically the same as ``web``, but starts the Celery worker with beat.

If you want to develop anything involving tasks, see the `Usage <_docker-usage-override-settings>`__ section below.

Image: data
^^^^^^^^^^^
The ``data`` container mounts several paths:

+--------------------------+----------------------------------+----------------------------------------------------+
| Folder in container      | Folder on host                   | Information                                        |
+==========================+==================================+====================================================+
| /var/lib/postgresql/data | <PROJECTROOT>/docker/postgres    | * Postgres data directory                          |
|                          |                                  | * Keeps the DB data even if container is removed   |
+--------------------------+----------------------------------+----------------------------------------------------+
| /srv/logs                | <PROJECTROOT>/docker/logs        | Django logs (see project settings)                 |
+--------------------------+----------------------------------+----------------------------------------------------+
| /srv/media               | <PROJECTROOT>/docker/media       | Django media files                                 |
+--------------------------+----------------------------------+----------------------------------------------------+
| /srv/project             | <PROJECTROOT>/docker/web/project | * the Django project                               |
|                          |                                  | * is copied on Dockerfile to get it up and running |
|                          |                                  | * then mounted over (the copy is overwritten)      |
+--------------------------+----------------------------------+----------------------------------------------------+
| /srv/pricemonitor        | <PROJECTROOT>                    | * the ``django-amazon-price-monitor`` lib          |
|                          |                                  | * is copied on Dockerfile to get it up and running |
|                          |                                  | * then mounted over (the copy is overwritten)      |
+--------------------------+----------------------------------+----------------------------------------------------+

Usage
~~~~~

.. _docker-usage-override-settings:

Override settings
^^^^^^^^^^^^^^^^^
To override some settings as well as to set up the **required AWS settings** you can create a ``docker-compose.override.yml`` and fill with the specific values
(also see `docker-compose documentation <https://docs.docker.com/compose/extends/>`__).

Please see or adjust the ``docker\web\project\settings.py`` for all settings that are read from the environment. They can be overwritten.

A sample ``docker-compose.override.yml`` file could look like this:
::

	version: '2'
	services:
	  celery:
		command: /bin/true
		environment:
		  PRICE_MONITOR_AWS_ACCESS_KEY_ID: XXX
		  PRICE_MONITOR_AWS_SECRET_ACCESS_KEY: XXX
		  PRICE_MONITOR_AMAZON_PRODUCT_API_REGION: DE
		  PRICE_MONITOR_AMAZON_PRODUCT_API_ASSOC_TAG: XXX
		  PRICE_MONITOR_AMAZON_PRODUCT_REFRESH_THRESHOLD_MINUTES: 5
		  PRICE_MONITOR_SUBSCRIPTION_RENOTIFICATION_MINUTES: 60

It will avoid the automatic startup of celery (``command: /bin/true``) and set the required settings for AWS (in fact they are only needed in the celery
container). You can then manually start the container and execute celery which is quite useful if you develop anything that includes changes in the tasks and
thus requires the celery to be restarted (execute from the ``docker`` folder!):

Start/Stop/Build
^^^^^^^^^^^^^^^^
Use the make file to execute the most common tasks. It will execute ``docker-compose`` with the project name ``pm`` resulting in the container's name pattern
``pm_*``.
::

	docker-build-base: - builds the base docker image
	docker-build-web:  - builds the web docker image
	docker-up:         - uses docker-compose to bring the containers up
	docker-stop:       - uses docker-compose to stop the containers
	docker-ps:         - runs docker-compose ps

A fixture with a Django user ``admin`` and the password ``password`` is loaded automatically.

Templates
---------
As the fronted is done by Angular, there is only a single template with very limited possibilities to adjust, ``price_monitor/angular_index_view.html``. You
can extends the template and adjust the following blocks.

footer
~~~~~~
Is rendered on the very bottom of the page. You have to use Bootstrap compatible markup, e.g.:
::

	{% block footer %}
		<div class="row">
			<div class="col-md-12">Additonal footer</div>
		</div>
	{% endblock %}

Management Commands
-------------------

price\_monitor\_batch\_create\_products
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A management command to batch create a number of products by providing
their ASIN:

::

    python manage.py price_monitor_batch_create_products <ASIN1> <ASIN2> <ASIN3>

price\_monitor\_recreate\_product
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Recreates a product with the given asin. If product already exists, it
is deleted. *Only use in development!*

::

    python manage.py price_monitor_recreate_product <ASIN>

price\_monitor\_search
~~~~~~~~~~~~~~~~~~~~~~

Searches for products at Amazon (not within the database) with the given
ASINs and prints out their details.

::

    python manage.py price_monitor_search <ASIN1> <ASIN2> ...

Loggers
-------

price\_monitor
~~~~~~~~~~~~~~

The app uses the logger "price\_monitor" to log all error and info
messages that are not included within a dedicated other logger. Please
see the `Django logging
documentation <https://docs.djangoproject.com/en/1.6/topics/logging/>`__
for how to setup loggers.

price\_monitor.product\_advertising\_api
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Logger for everything related to the ProductAdvertisingAPI wrapper class
that accesses the Amazon Product Advertising API through bottlenose.

price\_monitor.utils
~~~~~~~~~~~~~~~~~~~~

Logger for the utils module.
