topics : topics and partner interests

The lino_xl.lib.topics plugin adds the notions of "topics" and "interests" of a "partner" in a topic.

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

>>> import lino
>>> lino.startup('lino_book.projects.lydia.settings.doctests')
>>> from lino.api.doctest import *
>>> from django.db.models import Q


A topic is something a partner can be interested in. An interest is the fact that a given partner is interested in a given topic.

Users can see a panel "Interests" (InterestsByPartner) in the detail window of a partner.

They can add a row in that panel to specify that this partner is interested in a topic. They can open the panel in a window to delete interests.

A site administrator can configure the list of available topics.

>>> show_menu_path(topics.AllTopics)
Configure --> Topics --> Topics

The detail window of a topic has a panel "Interests" (InterestsByTopic) which shows the partners for which this topic is interesting.

A site administrator can see a global list of all interests. This might be useful e.g. for exporting the data.

>>> show_menu_path(topics.AllInterests)
Explorer --> Topics --> Interests


The application developer can decide what a "partner" means for the topics plugin by setting the Plugin.partner_model.

For example in Lino Tera the "partner" who can be interested in a topic is not Partner but Course.

>>> print(dd.plugins.topics.partner_model)

Because Topic defines a database field Topic.description the virtual field lino.core.model.Model.description is hidden:

>>> sorted(rt.models.topics.Topic._meta.private_fields, key=lambda f: str(f))
[lino_xl.lib.topics.models.Topic.description, lino_xl.lib.topics.models.Topic.name_column, lino_xl.lib.topics.models.Topic.navigation_panel, lino_xl.lib.topics.models.Topic.overview, lino_xl.lib.topics.models.Topic.workflow_buttons]
