module to deserialize a dictionary back into an object. Here's a simple example:
python
import json
# Assuming `dict_obj` is your dictionary
json_str = json.dumps(dict_obj)
block_instance = json.loads(json_str)
However, this will only work if the class of the object you're trying to deserialize is known and available in your current Python environment. If the class isn't available, you'll need to recreate it manually.
If you're working with custom classes (like a block instance in Prefect), you might need to write a custom deserialization function. This function would take a dictionary as input and return an instance of the desired class.
Remember, deserialization is the process of converting a serialized format - in this case, a dictionary - back into an object. It's the opposite of serialization, which is the process of converting an object into a format that can be easily stored or transmitted.

, how can I retrieve a block instance from that?Marvin

is the unique identifier of the block instance.
To retrieve the block instance, you can use the load
method of the Block
class in Prefect. Here's an example:
python
from prefect.blocks.core import Block
# Assuming `dict_obj` is your dictionary
block_document_id = dict_obj['$ref']['block_document_id']
block_instance = Block.load(block_document_id)
This will load the block instance with the given block_document_id
from Prefect's database.
Remember, blocks are a primitive within Prefect that enable the storage of configuration and provide an interface for interacting with external systems. They can securely store credentials for authenticating with services like AWS, GitHub, Slack, and any other system you'd like to orchestrate with Prefect.

SELECT block_name FROM blocks WHERE block_id = 'your-block-id'
Please replace 'your-block-id' with your actual block id.
