help : Make local help pages

The lino.modlib.help plugin adds functionality for loading extracted help texts at startup and optionally adding a Help button to all data views. See Help texts for a topic overview.

It defines some startup hooks and the django-admin command makehelp.

It also defines a database model for storing site contacts.

This is a tested document. The following instructions are used for initialization:

>>> import lino
>>> lino.startup('lino_book.projects.cms1.settings')
>>> from django.utils import translation
>>> from lino.api.doctest import *
>>> from django.db.models import Q
>>> from atelier.sheller import Sheller
>>> shell = Sheller()

The help button

As a site maintainer you can activate the Help button by setting help.make_help_pages to True.

Having a Help button requires the site to generate local help pages. So when this is True, call makehelp generate the help pages.

Site contacts

When help.use_contacts is set to True, the server administrator can edit a table of site contacts.

>>> rt.show(help.SiteContacts)
=================== =============== ==================== ================================= ================================= =================================
 Site contact type   Organization    Represented by       Remark                            Remark (de)                       Remark (fr)

The Site contact type field of a site contact points to the SiteContactTypes choicelist, which can be modified by the server administrator.

>>> rt.show(help.SiteContactTypes)
