Django app for linking to help pages with short tokens

Project description

Django app for linking to help pages with short tokens.

PyPI Travis Codecov Supported Python versions License


There are various factors that affect what help page an application should link to:

  • There may be a number of relevant books

  • The version of the application might affect which book to display

  • The application’s language might affect which book to display

This small Django app provides a means to use “help tokens” on the application pages, and then use those tokens, and various other settings, to determine the actual URL to use.


Help-tokens provides a context processor, and a redirection URL. Configuration is in a number of settings.


Help-tokens reads these Django settings to create URLs:

  • HELP_TOKENS_INI_FILE: Path to a .ini file containing help token definitions. The format of the ini file is described below.

  • HELP_TOKENS_BOOKS: a dictionary mapping book slugs to URLs. For example:

        'learner': '',
        'course_author': '',
  • HELP_TOKENS_VERSION: a string used as part of the final URL, to choose the correct version of the book. For example, “latest”.

  • HELP_TOKENS_LANGUAGE_CODE: the language code to use as part of the book URL, mapped through the [locales] section of the ini file.

INI file format

The .ini file pointed to by HELP_TOKENS_INI_FILE contains the definitions of the help tokens themselves.

The [pages] section defines the help tokens. Each help token definition consists of a book slug (defined in HELP_TOKENS_BOOKS), a colon, and a URL path. The default token is used for missing tokens. For example:

default = learner:index.html
instructor = learner:SFD_instructor_dash_help.html
course = learner:index.html

cohortmanual = course_author:course_features/cohorts/cohort_config.html#assign-learners-to-cohorts-manually
cohortautomatic = course_author:course_features/cohorts/cohorts_overview.html#all-automated-assignment

The [locales] section defines language codes, used with HELP_TOKENS_LANGUAGE_CODE to determine the language portion of the URL:

default = en
en = en
en_us = en

Context processor

The context processor is “help_tokens.context_processor”. It adds a function get_online_help_info. Call it with a help token, and it will return a dict with a doc_url entry, the help URL. You can use it like this in a template:

<a href="${get_online_help_info('visibility')['doc_url']}">...</a>

This interface is a bit verbose, but is to maintain backward compatibility with a previous implementation of this context processor.

Redirection view

The help_tokens.urls URLs define a view that redirects to a help URL. You can include it in your app:

# For redirecting to help pages.
url(r'^help_token/', include('help_tokens.urls')),

Then visiting help_token/foobar will redirect to the URL defined by the “foobar” help token.
