How to use it
-------------

First of all we have to specify where is allocated our config.
To do that we have to pass the following argument:

.. code-block:: python

--config=/path/of/my/config
..

If you do not provide a configuration path, by default the config is expected in the config folder.

In the configuration we are going to specify the following parameters to

.. code-block:: python

[oceandb]

enabled=true # In order to enable or not the plugin
module=bigchaindb # You can use one the plugins already created. Currently we have mongodb and bigchaindb.
module.path= # You can specify the location of your custom plugin.
db.hostname=localhost # Address of your bigchaindb nodes.
db.port=9985 # Port of your bigchaindb database.

# Bigchaindb specific config:
secret= # A secret that serves as a seed.
db.namespace=namespace # Namespace that you are going to use in bigchaindb
db.app_id= # App id of your bigchaindb application.
db.app_key= # App key of your bigchaindb application.
..

Once you have defined this the only thing that you have to do it is use it:

.. code-block:: python

oceandb = OceanDb(confPath)
tx_id = oceandb.write({"value": "test"}) #Write a new transaction in bdb.
oceandb.read(tx_id) #Read the content of this transaction
oceandb.update({"value": "update"},tx_id) #Update value of the transaction.
oceandb.delete(tx_id) #Delete transaction
..
