A tested document ¶

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

>>> from lino import startup
>>> startup('lino_book.projects.min9.settings.doctests')
>>> from lino.api.doctest import *

A course is when a "teacher" meets more or less regularily with a group of "pupils". The pupils can be any model (e.g. a contacts.Person). When a pupil participates in a course, we create an enrolment.

A course can automatically generate calendar entries for the meetings of that course according to recurrency rules. It helps with managing these meetings: schedule exceptions and manual date changes. It can fill the guests or participants of the meetings, and the teacher can register their presence. Courses can be grouped into course lines* (series), series into topics.

The internal name "courses" is for historic reasons. There was a time when I planned to rename "courses" to "activities". Some table names remind this time. In Lino Welfare they are called "workshops", in Lino Tera they are called "dossiers", in Lino Voga they are called "activities".

The `Course` model ¶

class lino_xl.lib.courses.Course¶

Database fields:

start_date¶: The start date of the first meeting to be generated.

end_date¶: The end date of the first meeting to be generated. Leave this field empty if the meetings last less than one day.

max_date¶: Don't generate meeting having their start date beyond this date.

enrolments_until¶

max_places¶: Available places. The maximum number of participants to allow in this course.

free_places¶: Number of free places.

requested¶: Number of requested places.

trying¶: Number of trying places.

confirmed¶: Number of confirmed places.

class lino_xl.lib.courses.Courses¶

Base table for all activities.

Filter parameters:

show_exposed¶

Whether to show or to hide courses in an exposed state.

That is, all courses in a state that has CourseState.is_exposed set to True.

This parameter is ignored if the state parameter is also specified.

state¶

class lino_xl.lib.courses.MyCourses¶: Show the courses authored by me (i.e. where I am the responsible manager). Compare MyCoursesGiven.

class lino_xl.lib.courses.MyCoursesGiven¶

Show the courses given by me (i.e. where I am the teacher). Compare MyCourses.

This requires the partner field in my user settings to point to me as a teacher.

For users whose partner field is empty, this list shows all courses without teacher.

class lino_xl.lib.courses.CoursesByLine¶: Show the courses per course line.

class lino_xl.lib.courses.CoursesByTopic¶: Shows the courses of a given topic.

The `Enrolment` model ¶

class lino_xl.lib.courses.Enrolment¶

An enrolment is when a given pupil plans to participate in a given course.

course_area¶

course¶

pupil¶

request_date¶

start_date¶

end_date¶

state¶: One of lino_xl.lib.courses.EnrolmentStates.

places¶

option¶

remark¶

confirmation_details¶

pupil_info¶: Virtual HtmlBox field showing the name and address of the participant.

class lino_xl.lib.courses.Enrolments¶: Base class for all tables that show Enrolment.

class lino_xl.lib.courses.AllEnrolments¶: Show global list of all enrolments.

class lino_xl.lib.courses.PendingRequestedEnrolments¶: Show all requested enrolments.

class lino_xl.lib.courses.PendingConfirmedEnrolments¶: Show all confirmed enrolments.

class lino_xl.lib.courses.EnrolmentsByPupil¶: Show all enrolments of a given pupil.

class lino_xl.lib.courses.EnrolmentsByCourse¶: Show the enrolments of a this course.

Notes about automatic calendar entry generation:

When an automatically generated entry is to be moved to another date, e.g. because it falls into a vacation period, then you simply change its date. Lino will automatically adapt all subsequent entries.
Marking an automatically generated event as "Cancelled" will not create a replacement event.

Enrolment workflow ¶

The state of an enrolment can be one of the following:

>>> rt.show('courses.EnrolmentStates')
======= =========== =========== ============= ============= ==============
 value   name        text        Button text   invoiceable   Uses a place
------- ----------- ----------- ------------- ------------- --------------
 10      requested   Requested                 No            No
 11      trying      Trying                    No            Yes
 20      confirmed   Confirmed                 Yes           Yes
 30      cancelled   Cancelled                 No            No
======= =========== =========== ============= ============= ==============

class lino_xl.lib.courses.EnrolmentStates¶

The list of possible states of an enrolment.

The default implementation has the following values:

requested¶

confirmed¶

cancelled¶: The enrolment was cancelled before it even started.

ended¶: The enrolment was was successfully ended.

abandoned¶: The enrolment was abandoned.

The `Slot` model ¶

class lino_xl.lib.courses.Slot¶

The `Line` model ¶

class lino_xl.lib.courses.Line¶

An activity line (or series) groups courses into a configurable list of categories.

We chose the word "line" instead of "series" because it has a plural form (not sure whether this idea was so cool).

name¶

The designation of this activity line as seen by the user e.g. when selecting the line.

One field for every language.

excerpt_title¶

The text to print as title in enrolments.

See also lino_xl.lib.excerpts.mixins.ExcerptTitle.excerpt_title.

body_template¶: The body template to use when printing an activity of this line. Leave empty to use the site's default (defined by body_template on the lino_xl.lib.excerpts.models.ExcerptType for Course)

course_area¶: Pointer to CourseAreas. This is used only when an application defines several variants of EnrolmentsByPupil.

Course areas ¶

TODO: rename "course area" to "activity layout"?

The CourseAreas choicelist is a place for defining different layouts of courses. The area of a course determines how this course is being show on screen and whether presences of the participants are being managed or not.

The default configuration contains only one choice:

>>> rt.show(courses.CourseAreas)
======= ========= ============ =================
 value   name      text         Table
------- --------- ------------ -----------------
 C       default   Activities   courses.Courses
======= ========= ============ =================

Usage examples see Activities in Lino Voga and Therapies.

class lino_xl.lib.courses.CourseAreas¶: The global choicelist of course areas. Every choice is an instance of CourseArea.

class lino_xl.lib.courses.CourseArea¶

courses_table¶: Which table to use for showing courses in this course area.

The state of a course ¶

>>> rt.show(courses.CourseStates)
======= ========== ========== ========= ========== ============= =================
 value   name       text       Exposed   Editable   Invoiceable   Update calendar
------- ---------- ---------- --------- ---------- ------------- -----------------
 10      draft      Draft      Yes       Yes        No            No
 20      active     Started    Yes       No         Yes           No
 30      inactive   Inactive   No        No         No            No
 40      closed     Closed     No        No         No            No
======= ========== ========== ========= ========== ============= =================

class lino_xl.lib.courses.CourseStates¶

draft¶

active¶

inactive¶

closed¶

Every course state has itself some additional attributes that are used to group them at certain places.

class lino_xl.lib.courses.CourseState¶

is_editable¶

is_exposed¶

is_invoiceable¶

auto_update_calendar¶

For example you can retrieve a list of course states that are to be considered "exposed" (Courses.show_exposed):

>>> courses.CourseStates.filter(is_exposed=True)
[<CourseStates.draft:10>, <CourseStates.active:20>]

>>> courses.CourseStates.filter(is_exposed=False)
[<CourseStates.inactive:30>, <CourseStates.closed:40>]

As an application developer you can redefine the items of CourseStates in order to adapt it to the needs of your application.

TODO: Write a tutorial about redefining choicelists.

Actions ¶

class lino_xl.lib.courses.ConfirmAllEnrolments¶

Plugin configuration ¶

class lino_xl.lib.courses.Plugin¶

teacher_model = 'contacts.Person'

pupil_model = 'contacts.Person'

pupil_name_fields = "pupil__name"

The value to use as quick_search_fields for Enrolment.

Note that this remains a text string while quick_search_fields is resolved into a tuple of data elements at site startup.

Presence sheet ¶

The presence sheet of a course is a printable document For example Presence sheet.

presence_sheet.weasy.html¶: The template used for printing a presence sheet of an activity (both versions pdf and html)
