Access Tokens

In order to be able to access your Trello's boards, first you need to generate an access token.

1. Go to https://trello.com/app-key, and retrieve your application key.
2. Run ./bin/generate_access_token.py as described below and open the link it prints.

$ python bin/generate_access_token.py -h
usage: generate_access_token.py [-h] -c CLIENT_API_KEY -a APP_NAME
                                [-e EXPIRATION] [-w]

optional arguments:
  -h, --help            show this help message and exit
  -c CLIENT_API_KEY, --client-api-key CLIENT_API_KEY
                        your app's client api key
  -a APP_NAME, --app-name APP_NAME
                        your app's name
  -e EXPIRATION, --expiration EXPIRATION
                        the token's expiration, defaults to 30days
  -w, --write-access    the token has write access


$ python ./bin/generate_access_token.py --client-api-key <my_app_key> --app-name TEST
Access the following link to generate your access token:
https://trello.com/1/authorize?key=my_app_key&name=TEST&expiration=30days&response_type=token&scope=read

3. Copy the generated token to a place safe!

Available Transformers

• Markdown
• AsciiDoc
• Atlassian Confluence

Sample

The following will retrieve all Trello lists from a given Trello board, and print it to stdout using a specific transformer:

trello = TrelloApi(args['client_api_key'])
trello.set_token(args['token'])
extraction = TrelloExtraction(trello, args['board_id'])
print(extraction.apply_transformer(MarkdownTransformer()))

Jinja2 Templating

You can also apply a Jinja2 template to render the board items.

The rendering is called with the following context:

• {'title', board_name, 'board_lists': board_lists}
  • board_lists is a list of List = namedtuple('List', ['id', 'name', 'cards'])
  • cards is a list of Card = namedtuple('Card', ['id', 'name', 'comments', 'voters'])
  • comments is a list of Comment = namedtuple('Comment', ['text', 'author'])
  • voters is a list of strings containing the full name of each voter

An example is given in bin/jinja_template.py.

extraction = TrelloExtraction(trello, args['board_id'])

template = '''
# {{ title }}

{% for board_list in board_lists %}
## {{ board_list.name }}
    {% for card in board_list.cards %}
- {{ card.name }}
        {% if card.comments %}
            {% for comment in card.comments %}
    - comment by {{ comment.author }}: {{ comment.text }}
            {% endfor %}
        {% endif %}
        {% if card.voters %}
    - {{ card.voters|length }} vote(s), by: {{ card.voters | join(', ') }}
        {% endif %}
    {% endfor %}

{% endfor %}
'''
extraction.apply_template(jinja2.Template(template,
                                          trim_blocks=True,
                                          lstrip_blocks=True))
