Creating and Updating Custom Entities

Custom entities can be created and updated with

create_or_update_custom_entity(self, entity_name: str, folder_id: str, schema_id: str, registry_id: str, author_id=None, custom_entity_fields=None, if_exists="fail")

Here is an example of creating a custom entity from the columns of a dataframe. If the entity already exists, the method will update it if if_exists = "update".

from ganymede_sdk.api.benchling import Benchling
from ganymede_sdk import Ganymede


REGISTRY_ID = "src_"
FOLDER_ID = "lib_"
ENTITY_SCHEMA_ID = "ts_"
AUTHOR_ID = "ent_"

g = Ganymede()
b = Benchling(g.ganymede_context)


for entity_name, entity_var in df[["entity_name", "entity_var"]].itertuples(
    index=False
):
    entity_dict = b.get_models_to_map(
        b.get("custom_entities", benchling_filter={"name": entity_var})
    )

    custom_entity = b.create_or_update_custom_entity(
        entity_name,
        FOLDER_ID,
        ENTITY_SCHEMA_ID,
        REGISTRY_ID,
        author_id=AUTHOR_ID
        if_exists="update",
        custom_entity_fields={
            "Some Other Entity": entity_dict.get(entity_var, None),
        },
    )

    custom_entities.update({**entity_dict, **custom_entity})

df[["entity_name", "entity_var"]] = df[["entity_name", "cell_entity_var"]].replace(custom_entities)

Data Retrieval from Benchling

The Benchling object contains methods to retrieve data from Benchling. The methods are

get(self, service: str, *args, as_dict: bool = True, benchling_filter: Optional[Dict] = None, **kwargs)
get_assay_result_schema_table(self, assay_result_id: str)
get_fields_data(self, service: str, *args, benchling_filter: Optional[Dict] = None, **kwargs)

Retrieve data (IDs, names, ...)

The get method is used to retrieve data from Benchling such as custom_entities, assay_results, schemas, plates, etc. To see available services, use

from ganymede_sdk.api.benchling import Benchling
from ganymede_sdk import Ganymede

g = Ganymede()
b = Benchling(g.ganymede_context)
b.list_available_services()

Example of using this method to get custom entities and plates information

from ganymede_sdk.api.benchling import Benchling
from ganymede_sdk import Ganymede

g = Ganymede()
b = Benchling(g.ganymede_context)

# retrieve all custom entities
custom_entities = b.get('custom_entities')

# retrieve custom entities with names "ent1" and "ent2"
custom_entities = b.get('custom_entities', names_any_of=['ent1', 'ent2'])

# retrieve custom entities by Benchling IDs
custom_entities = b.get('custom_entities', ids=['bfi_1234', 'bfi_5678'])

# retrieve plate named "my_plate_name"
test_plate = b.get('plates', benchling_filter={'name': 'my_plate_name'})[0]

Retrieve Schema Table

The get_assay_result_schema_table method retrieves the schema table for an assay result using its ID. This method can be used to see which columns to keep in your dataframe or how to name them.

from ganymede_sdk import Ganymede
from ganymede_sdk.api.benchling import Benchling

g = Ganymede()
b = Benchling(g.ganymede_context)

result_id = "example_result_id"
schema_table = b.get_assay_result_schema_table(result_id)

You can validate your dataframe against the schema using

validate_assay_result_schema_names(self, df: pd.DataFrame, assay_result_id: str)

Retrieve Data in Entities and Results

get_fields_data gets a Pandas DataFrame of Benchling service field results such as custom_entity and assay results data. For assay results, you must pass the schema ID starting with assaysch_.

from ganymede_sdk.api.benchling import Benchling
from ganymede_sdk import Ganymede

g = Ganymede()
b = Benchling(g.ganymede_context)

# Get data frame of fields returned from custom entities and assay_results
df_custom_entity_fields = b.get_fields_data("custom_entity")
df_assay_result_fields = b.get_fields_data("assay_results", "assaysch_1234")

Data Upload to Benchling

The Benchling object contains methods to upload to Benchling. The methods are

create_assay_results_from_dataframe(self, data: Union[pd.DataFrame, List[pd.DataFrame]], schema_id: str, project_id: str, replace_special_characters: bool = True, ignore_na: bool = True, upload: bool = True, **kwargs)
create_benchling_ids_from_files(self, files: Dict[str, bytes], process_file_names: bool = False)

Uploading Files - create_benchling_ids_from_files

This method can be used to upload files to Benchling and return the IDs of the files. The returned object is a dictionary mapping the file name to the ID. You can use this dictionary to link / associate values in your data to the created files.

from ganymede_sdk.api.benchling import Benchling
from ganymede_sdk import Ganymede
import pandas as pd

g = Ganymede()
b = Benchling(g.ganymede_context)

# Get the IDs for two files that are uploaded to Benchling

file_ids = b.create_benchling_ids_from_files(
    {"Filename1.csv": file1, "Filename2.csv": file2}, process_file_names=True
) # where file_ids.keys() = ['filename1csv', 'filename2csv']"

file_ids = b.create_benchling_ids_from_files(
    {"Filename1.csv": file1, "Filename2.csv": file2}
) # where file_ids.keys() = ['Filename1.csv', 'Filename2.csv']"

Uploading Assay Results - create_assay_results_from_dataframe

This method can be used to upload assay results to Benchling. You can use create_ids_from_files to associate rows in your dataframe with uploaded benchling files.

from ganymede_sdk.api.benchling import Benchling
from ganymede_sdk import Ganymede

g = Ganymede()
b = Benchling(g.ganymede_context)

# Create or update the entity
custom_entity_id = b.create_or_update_custom_entity(
    entity_name, folder_id, schema_id, registry_id,
    author_id=None, custom_entity_fields=None, if_exists="fail",
)

# Create file IDs and get dropdown IDs
file_ids = b.create_benchling_ids_from_files({"filename1": file1, "filename2": file2})
dropdown_ids = {dropdown["name"]: dropdown["id"] for dropdown in b.get("dropdowns")}

# Use pandas.DataFrame.replace to link entries in your dataframe with Benchling IDs
# or manually add IDs to the dataframe.
dataframe = dataframe.replace({**custom_entity_id, **file_ids, **dropdown_ids})

# Upload dataframe to Benchling as Assay Results
assay_results = b.create_assay_results_from_dataframe(
    dataframe, schema_id, project_id, drop_na=True, upload=True
)
