in-layers-data 0.4.0

A data layer for In Layers Core. (in-layers-core). Part of the Node in Layers ecosystem

In Layers Data

A data layer for the In Layers Core framework.

NOTE: There are no explicit dependencies on any database. To use a specific database you must install it in your own system. These databases are "imported in" as the databases are actually used at runtime.

How To Use

1. Install in-layers-data
2. Set "in_layers_data" to the in_layers_core.models.model_backend property
3. Add in_layers_data configuration to your config
4. Install database libraries to use. Example: pymongo or boto3

Configuration Example

# config_base.py
from box import Box
def get_base_config():
    return Box(
        ...,
        in_layers_core=Box(
            ...
            models=Box(
                model_backend="in_layers_data",
            )
        ),
        in_layers_data=Box(
            default=Box(
                type="mongodb"
                # Connection information here
            ),
            # Optional: Set "domain" or "domain.ModelPluralNames" to a specific database configuration.
            # model_to_backend=Box(
            #     "domain.ModelPluralNames"=Box(
            #         type="mongodb",
            #         host="different-host"
            #     )
            # )
        )
    )

Key Features

• Drop in, Swappable Databases
• Multi-database support
• Low dependencies

Databases Supported

• Mongodb

Database Info

Mongo

Mongodb requires pymongo

Dynamodb

Dynamodb requires boto3

Important

Dynamodb is very poor at performing search queries. While this is implemented, it is not-recommended for use. Instead use the retrieve.
