Define a new view displaying events in an interactive visualization
chart.
The widget is based on the external library

Configuration
=============
You need to define a view with the tag <timeline> as base element. These
are the possible attributes for the tag:
+------------------+-----------+-------------------------------------+
| Attribute | Required? | Description |
+==================+===========+=====================================+
| date_start | **Yes** | Defines the name of the field of |
| | | type date that contains the start |
| | | of the event. |
+------------------+-----------+-------------------------------------+
| date_stop | No | Defines the name of the field of |
| | | type date that contains the end of |
| | | the event. The date_stop can be |
| | | equal to the attribute date_start |
| | | to display events has 'point' on |
| | | the Timeline (instantaneous event). |
+------------------+-----------+-------------------------------------+
| date_delay | No | Defines the name of the field of |
| | | type float/integer that contain the |
| | | duration in hours of the event, |
| | | default = 1. |
+------------------+-----------+-------------------------------------+
| default_group_by | **Yes** | Defines the name of the field that |
| | | will be taken as default group by |
| | | when accessing the view or when no |
| | | other group by is selected. |
+------------------+-----------+-------------------------------------+
| zoomKey | No | Specifies whether the Timeline is |
| | | only zoomed when an additional key |
| | | is down. Available values are '' |
| | | (does not apply), 'altKey', |
| | | 'ctrlKey', or 'metaKey'. Set this |
| | | option if you want to be able to |
| | | use the scroll to navigate |
| | | vertically on views with a lot of |
| | | events. |
+------------------+-----------+-------------------------------------+
| mode | No | Specifies the initial visible |
| | | window. Available values are: 'day' |
| | | to display the current day, 'week', |
| | | 'month' and 'fit'. Default value is |
| | | 'fit' to adjust the visible window |
| | | such that it fits all items. |
+------------------+-----------+-------------------------------------+
| margin | No | Specifies the margins around the |
| | | items. It should respect the JSON |
| | | format. For example |
| | | '{"item":{"horizontal":-10}}'. |
| | | Available values are: |
| | | '{"axis":<number>}' (The minimal |
| | | margin in pixels between items and |
| | | the time axis) '{"item":<number>}' |
| | | (The minimal margin in pixels |
| | | between items in both horizontal |
| | | and vertical direction), |
| | | '{"item":{"horizontal":<number>}}' |
| | | (The minimal horizontal margin in |
| | | pixels between items), |
| | | '{"item":{"vertical":<number>}}' |
| | | (The minimal vertical margin in |
| | | pixels between items), |
| | | '{"item":{"horizont |
| | | al":<number>,"vertical":<number>}}' |
| | | (Combination between horizontal and |
| | | vertical margins in pixels between |
| | | items). |
+------------------+-----------+-------------------------------------+
| event_open_popup | No | When set to true, it allows to edit |
| | | the events in a popup. If not |
| | | (default value), the record is |
| | | edited changing to form view. |
+------------------+-----------+-------------------------------------+
| stack | No | When set to false, items will not |
| | | be stacked on top of each other |
| | | such that they do overlap. |
+------------------+-----------+-------------------------------------+
| colors | No | Allows to set certain specific |
| | | colors if the expressed condition |
| | | (JS syntax) is met. |
+------------------+-----------+-------------------------------------+
| dependency_arrow | No | Set this attribute to a x2many |
| | | field to draw arrows between the |
| | | records referenced in the x2many |
| | | field. |
+------------------+-----------+-------------------------------------+
Optionally you can declare a custom template, which will be used to
render the timeline items. You have to name the template
'timeline-item'. These are the variables available in template
rendering:
- ``record``: to access the fields values selected in the timeline
definition.
- ``formatters``: used to format values (see available functions in
``@web/views/fields/formatters``).
- ``parsers``: used to parse values (see available functions in
``@web/views/fields/parsers``).
You also need to declare the view in an action window of the involved
model.
See ``web_timeline/demo/ir_cron_view.xml`` for a very basic timeline
view example added onto cron tasks.
More evolved example, from ``project_timeline``:
.. code:: xml
<?xml version="1.0" encoding="utf-8"?>
<odoo>
<record id="view_task_timeline" model="ir.ui.view">
<field name="model">project.task</field>
<field name="type">timeline</field>
<field name="arch" type="xml">
<timeline date_start="date_assign"
date_stop="date_end"
string="Tasks"
default_group_by="project_id"
event_open_popup="true"
colors="white: user_ids == []; #2ecb71: state == '1_done'; #ec7063: state == '1_canceled'"
dependency_arrow="depend_on_ids"
>
<field name="user_ids" />
<field name="allocated_hours" />
<templates>
<t t-name="timeline-item">
<div class="o_project_timeline_item">
<t t-foreach="record.user_ids" t-as="user" t-key="user.id">
<img
t-if="record.user_ids"
t-attf-src="/web/image/res.users/#{user}/image_128/16x16"
t-att-title="record.user"
width="16"
height="16"
class="mr8"
alt="User"
/>
</t>
<span name="display_name">
<t t-esc="record.display_name" />
</span>
<small
name="allocated_hours"
class="text-info ml4"
t-if="record.allocated_hours"
>
<t
t-out="formatters.get('float_time')(record.allocated_hours)"
/>
</small>
</div>
</t>
</templates>
</timeline>
</field>
</record>
<record id="project.action_view_task" model="ir.actions.act_window">
<field
name="view_mode"
>kanban,tree,form,calendar,timeline,pivot,graph,activity</field>
</record>
</odoo>
Usage
=====
For accessing the timeline view, you have to click on the button with
the clock icon in the view switcher. The first time you access to it,
the timeline window is zoomed to fit all the current elements, the same
as when you perform a search, filter or group by operation.
You can use the mouse scroll to zoom in or out in the timeline, and
click on any free area and drag for panning the view in that direction.
The records of your model will be shown as rectangles whose widths are
the duration of the event according our definition. You can select them
clicking on this rectangle. You can also use Ctrl or Shift keys for
adding discrete or range selections. Selected records are hightlighted
with a different color (but the difference will be more noticeable
depending on the background color). Once selected, you can drag and move
the selected records across the timeline.
When a record is selected, a red cross button appears on the upper left
corner that allows to remove that record. This doesn't work for multiple
records although they were selected.
Records are grouped in different blocks depending on the group by
criteria selected (if none is specified, then the default group by is
applied). Dragging a record from one block to another change the
corresponding field to the value that represents the block. You can also
click on the group name to edit the involved record directly.
Double-click on the record to edit it. Double-click in open area to
create a new record with the group and start date linked to the area you
clicked in. By holding the Ctrl key and dragging left to right, you can
create a new record with the dragged start and end date.
Known issues / Roadmap
======================
- Implement a more efficient way of refreshing timeline after a record
update;
- Make ``attrs`` attribute work;
- When grouping by m2m and more than one record is set, the timeline
item appears only on one group. Allow showing in both groups.
- When grouping by m2m and dragging for changing the time or the group,
the changes on the group will not be set, because it could make
disappear the records not related with the changes that we want to
make. When the item is showed in all groups change the value
according the group of the dragged item.
- When an item label does not fit in its date-range box: ✅ the label
correctly overflows the box; ✅ clicking anywhere on the label allows
moving the box; ❌ double-clicking the label outside of the box does
not open that item.
