metabase-api 0.1.2

A Python Wrapper for Metabase API

Installation

pip install metabase-api

Initializing

from metabase_api import Metabase_API

mb = Metabase_API('https://...', 'username', 'password')  # if password is not given, it will prompt for password

Functions

REST functions (get, post, put, delete)

Calling Metabase API endpoints (documented here) can be done using the corresponding REST function in the wrapper.
E.g. to call the endpoint GET /api/database/, use mb.get('/api/database/').

Custom Functions

There are several custom functions such as move_to_archive, get_collection_id, get_db_id, .... the main custom function is the create_card function which is described below.

create_card function

• You need to provide a name for the card, tell the function which table to use as the source of data and optionally say in which collection to save the card (if no collection is given the card is saved in the root collection).

mb.create_card(card_name='test_card', table_name='mySourceTable')

• Using the column_order parameter we can specify how the order of columns should be in the created card. Accepted values are 'alphabetical', 'db_table_order' (default), or a list of column names.

mb.create_card(card_name='test_card', table_nam='mySourceTable', column_order=['myCol5', 'myCol3', 'myCol8'])

• All or part of the function arguments and many more information (e.g. visualisation settings) can be provided to the function in a dictionary (using the custom_json parameter).

mb.create_card(custom_json=myCustomJson)

It's very helpful to use the Inspect tool of the browser (network tab) to see what Metabase is doing. You can then use the generated json code to build your automation. To turn the generated json in the browser into a Python dictionary, you can copy the code, paste it into triple quotes (''' '''') and apply the function make_json:

raw_json = ''' {"name":"test","dataset_query":{"database":165,"query":{"fields":[["field-id",35839],["field-id",35813],["field-id",35829],["field-id",35858],["field-id",35835],["field-id",35803],["field-id",35843],["field-id",35810],["field-id",35826],["field-id",35815],["field-id",35831],["field-id",35827],["field-id",35852],["field-id",35832],["field-id",35863],["field-id",35851],["field-id",35850],["field-id",35864],["field-id",35854],["field-id",35846],["field-id",35811],["field-id",35933],["field-id",35862],["field-id",35833],["field-id",35816]],"source-table":2154},"type":"query"},"display":"table","description":null,"visualization_settings":{"table.column_formatting":[{"columns":["Diff"],"type":"range","colors":["#ED6E6E","white","#84BB4C"],"min_type":"custom","max_type":"custom","min_value":-30,"max_value":30,"operator":"=","value":"","color":"#509EE3","highlight_row":false}],"table.pivot_column":"Sale_Date","table.cell_column":"SKUID"},"archived":false,"enable_embedding":false,"embedding_params":null,"collection_id":183,"collection_position":null,"result_metadata":[{"name":"Sale_Date","display_name":"Sale_Date","base_type":"type/DateTime","fingerprint":{"global":{"distinct-count":1,"nil%":0},"type":{"type/DateTime":{"earliest":"2019-12-28T00:00:00","latest":"2019-12-28T00:00:00"}}},"special_type":null},{"name":"Account_ID","display_name":"Account_ID","base_type":"type/Text","fingerprint":{"global":{"distinct-count":411,"nil%":0},"type":{"type/Text":{"percent-json":0,"percent-url":0,"percent-email":0,"average-length":9}}},"special_type":null},{"name":"Account_Name","display_name":"Account_Name","base_type":"type/Text","fingerprint":{"global":{"distinct-count":410,"nil%":0.0015},"type":{"type/Text":{"percent-json":0,"percent-url":0,"percent-email":0,"average-length":21.2916}}},"special_type":null},{"name":"Account_Type","display_name":"Account_Type","base_type":"type/Text","special_type":"type/Category","fingerprint":{"global":{"distinct-count":5,"nil%":0.0015},"type":{"type/Text":{"percent-json":0,"percent-url":0,"percent-email":0,"average-length":3.7594}}}}],"metadata_checksum":"7XP8bmR1h5f662CFE87tjQ=="} '''
myJson = mb.make_json(raw_json, prettyprint=True)
mb.create_card('test_card2', table_name='mySourceTable', custom_json={'visualization_settings':myJson['visualization_settings']})

Notes

• There are also two other Python wrappers for Metabase API here and here.
