ResDB-ORM¶
ResDB-ORM is a Python module designed to simplify interactions with ResilientDB's key-value store database by providing an Object-Relational Mapping (ORM) interface. This library allows developers to use basic CRUD functionalities with ease.
Prerequisites¶
Before using this repository, ensure that the following services are running:
-
kv_server: This is the key-value store server that forms the backend for ResilientDB. Follow the instructions in the ResilientDB repository to set it up and start it.
-
ResilientDB-GraphQL: This provides a GraphQL interface to interact with ResilientDB. Follow the instructions in the ResilientDB-GraphQL repository to set it up and start it.
Setting up Prerequisites¶
You can use the provided INSTALL.sh script to automatically install and set up both the kv_server and ResilientDB-GraphQL services. The script will clone the necessary repositories, build the services, and start them.
To use the INSTALL.sh script:
git clone https://github.com/ResilientEcosystem/ResDB-ORM.git
cd ResDB-ORM
./INSTALL.sh
Installation¶
ResDB-ORM is also available on PyPI and can be installed using pip:
pip install resdb-orm
Once the above services are running, follow the steps below to set up and use ResDB-ORM.
1. Clone this Repository¶
git clone https://github.com/ResilientEcosystem/ResDB-ORM.git
cd ResDB-ORM
Note: The script may require sudo privileges to install dependencies and set up services.
2. Create and Activate a Virtual Environment¶
Set up a virtual environment to manage dependencies:
python3 -m venv venv
source venv/bin/activate
3. Install Dependencies¶
Ensure that you have all necessary dependencies installed:
pip install -r requirements.txt
4. Configure config.yaml
¶
Update the config.yaml
file to point to the correct Crow endpoint. After running ResilientDB-GraphQL, you should see output similar to the following:
(2024-08-17 00:03:53) [INFO ] Crow/1.0 server is running at <CROW_ENDPOINT> using 16 threads
(2024-08-17 00:03:53) [INFO ] Call `app.loglevel(crow::LogLevel::Warning)` to hide Info level logs.
<CROW_ENDPOINT>
in the config.yaml
file with the actual endpoint URL from the above output.
5. Verify Installation¶
Run the provided test.py
script to verify that everything is set up correctly:
python test.py
6. Import the Module in Your Own Code¶
You can now import and use the ResDBORM
module in your own projects:
from resdb_orm.orm import ResDBORM
Initialize the ORM¶
orm = ResDBORM()
# Example usage: Create a new record
data = {"key": "value"}
record_id = orm.create(data)
print(f"Record created with ID: {record_id}")`
