Creating a database
Database classes are used to persist key/value pairs in a database. Values can be a complex object such as an array or a dictionary.
The class has three mandatory methods,
connect should initialise a connection to a database and store that connection object as a property of the database module instance.
put stores an object for a given key.
get returns an object for a given key. The object which is returned should be equivalent to the object which was stored.
# We recommend you use the official library # for your database and import it here import databaselibrary # Import opsdroid dependencies from opsdroid.database import Database class MyDatabase(Database): async def connect(self, opsdroid): # Create connection object for database self.connection = await databaselibrary.connect() async def put(self, key, value): # Insert the object into the database response = await self.connection.insert(key, value) # Return a bool for whether the insert was successful return response.success async def get(self, key): # Get the object from the database and return it return await self.connection.find(key)
