API reference

configure_and_or_load(table_table, db_path, load)

Given a path to a table table file (table.tsv), a directory in which to find/create a database: configure the database using the configuration which can be looked up using the table table, and optionally load it if the load flag is set to true.

Returns the configuration map back as a JSON string.

Given a config map represented as a JSON string, a directory containing the database, the table name and column name from which to retrieve matching values, return a JSON array (represented as a string) of possible valid values for the given column which contain the matching string (optional) as a substring (or all of them if no matching string is given). The JSON array returned is formatted for Typeahead, i.e., it takes the form: [{"id": id, "label": label, "order": order}, ...].

validate_row(config, db_path, table_name, row, existing_row, row_number)

Given a config map represented as a JSON string, a directory in which to find the database, a table name, a row, and if the row already exists in the database, its associated row number (optional), perform both intra- and inter-row validation and return the validated row as a JSON string.

update_row(config, db_path, table_name, row, row_number)

Given a config map represented as a JSON string, a directory in which the database is located, a table name, a row represented as a JSON string, and its associated row number, update the row in the database.
