As the name suggests, this view type presents the records in a calendar that can be viewed for month, week, or days periods of time. A calendar view for the To-Do Tasks could look like this:
<record id="view_calendar_todo_task" model="ir.ui.view">
<field name="model">todo.task</field>
<field name="arch" type="xml">
<calendar date_start="date_deadline" color="user_id"
display="[name], Stage [stage_id]" >
<!-- Fields used for the display text -->
<field name="name" />
<field name="stage_id" />
</calendar>
</field>
</record>
The calendar attributes are:
date_start is the field for the start date. Mandatory.date_end is the field for the end date. Optional.date_delay is the field with the duration in days, that can be used instead of date_end.all_day provides the name of a Boolean field that is to be used to signal full day events.
