Tutorial: App Buttons

Let's learn how to add App Buttons for running your script.

Usecase: Count Cards

In this tutorial, we'll add a button that counts the number of cards in a board, and adds the count to the board name.

Enter the following code into your script:

Python

import trello_app

def count_cards():
    # get old board name
    board = trello_app.get_current_board()
    old_board_name = board.get_name().split(" [")[0]

    # get all open cards
    card_count = len(board.get_cards(filter="open"))

    # set board name with card counts
    board.set_name("%s [%s]" % (old_board_name, card_count))

Run the script from your editor

We can test this script by clicking the Run button as follows.

Using an App Button

Rather than only use the Run button in the editor, we can also close the editor and use an App Button.

Go back to the app. Rather than clicking the Blockspring leaf to open the editor, hover and click on your function name (in this case count_cards).
