A simple program which leverages Tableau's client server python module (TSC) [link] and slack API module (SlackClient)[link] to delivery Tableau Views to Slack.

At the end of the program you will be able to query tableau server client for a specific view. You will then download this view as a png image and post it to a specific slack channel.

1. Python3
2. Tableau Client Server (with credentials)
3. Slack API Token

1. Download the repo by running git clone https://github.com/etav/tableau_view_to_slack.git
2. Activate virtual env 3 OR install modules contained in the requirements.txt file to your local python version by running pip install -r requirements.txt in that directory.
3. Edit the "config.ini" file with the following info for Tableau: a) user: tableau username to log into the server. b) pass: tableau password to log into the server. c) server: the url for your tableau server, ie: http://tab.mydomain.com. d) view: the name of the view you'd like to send to slack. e) png_path: the desired download path for the png file.
4. Edit the "config.ini" file with the following info for Slack: a) token: A slack token you created previously. b) channel: The name of an existing slack channel.
5. Run the program & head to the slack channel to view the png.

Opening yaml config file to unpack assets for slack & tableau

with open("config.yml", 'r') as yml:
    config = yaml.load(yml, Loader=yaml.FullLoader)

Sign into tableau using authentication resources defined in the yaml file and filter for specific view name on the site's server.

with server.auth.sign_in(tableau_auth):

# initialize filter object
req_option = tsc.RequestOptions(pagesize=1000)

# filter for specific "view_name"
req_option.filter.add(tsc.Filter(tsc.RequestOptions.Field.Name, tsc.RequestOptions.Operator.Equals, view_name))
my_view, pagination_item = server.views.get(req_option)

However, we once we find the view we need to populate it with the image data, using the following: ```python # populate view image server.views.populate_image(my_view)

    file_name = 'view_image_{}.png'.format(view_name)
    with open(path+file_name, 'wb') as f:
        f.write(my_view.image)
        print('Success! PNG generated for view: {}'.format(view_name))
        print('{} file generated at {}'.format(file_name, path))
    ```
