Task #1937160

Purpose
=======

Performance improvement:

The members_count computed field now uses a compute_sudo with
a read_group allowing to compute all the members_count of the recordset
in a single query.

the field from the model as it's now useless.

Task : 1908654

closes odoo/odoo#28976

On a sale order, the delivery carrier choice was done directly
on the form view. To get an estimated delivery price, the user need to
click 'add to order' to create a delivery fee line. To get the exact
delivery price on the sale order, the user needed to leave the sale
order without delivery line in order to get the exact price from the
picking at its validation.
As this flow was not so clear, this commit adds a new wizard to choose
the delivery carrier and check its commition fees. This add a line in
any case.

The wizard will be launched from a new button on the sale order

Task : 1908654

The delivery carriers get a new field to specify the invoicing
policy. The two cases are :
  - Estimated cost: the delivery price is charged directly on
the sale order based on the estimated fee
  - Real cost: the delivery price is estimated from the sale order
but not added in the delivery line (we get a line with quantity=1 and price = 0).
Once the delivery is validated, the delivery price is recomputed.
The new price depends on the integration level. If it's 'rate', the price is
the estimated one (carrier.rate_shipment()). If it's 'rate_and_ship, the price
is the one given by the carrier at the delivery

The bases carriers (fixed_on_rule and base) always use 'Estimated Cost'
as their price should not be changed between the sale order creation
and delivery validation

Task : 1908654

Purpose of this merge is to be able to sell courses [1] when using the
slides / eLearning platform.

This commit adds sale capabilities on a slide.channel. A slide.channel can
now have the 'payment' visibility, that requires a 'product_id' configured
on the channel.

When a customer purchases a product linked to a channel, he is added to the
members of the channel (see slide.channel.partner_ids) when his order is
confirmed.

This merge is linked to task ID 1937160 and PR #30914. Future tasks will
improve homepage of channels and clearly show public, private and payment
based channels [2].

[1] see task ID 1902304 (main eLearning task) PR #29876;
[2] see task ID 1936153 (new homepage for slides) PR #30770;

Purpose
=======

With the new 'website_slides_sale' module users can now sell slide.channels.

This commit adds a setting to let the user know he has to install website_sale
to be able to sell courses / documentation.

Purpose
=======

Currently, the slide_channels having a visibility configured as 'invite' could
only add members manually.

This commit adds an 'Invite' button on top of the slide channel form that opens
a wizard allowing to send emails to contacts and also make them members of the
related slide channel.

Task #1937160

Purpose
=======

This commit adds a "Attendees" stat button on the slide.channel form view
showing the members (partner_ids) count.

On click, it redirects to a tree view of slide.channel.partner. The tree
view is configured as editable to be able to administrate members
(add/update/delete).

Task #1937160

Purpose
=======

This commit adds sale capabilities to a slide.channel. A slide.channel can
now have the 'payment' visibility, that requires a 'product_id' configured
on the channel.

When a customer purchases a product linked to a channel, he is added to the
members of the channel (see slide.channel.partner_ids) when his order is
confirmed.

The feature is added in a new module 'website_sale_slides' that comes as a
bridge auto-installed between 'website_slides' and 'website_sale'.

The final goal is to be able to sell "courses" (see task #1902304).

closes odoo/odoo#24802

Purpose of this merge is to prepare eLearning feature by already modifying
channel model.

It includes

 * addition of tag and tag groups on channel, allowing to filter and search;
 * addition of statistics computation on channel, notably tracking completion
   of users;
 * removal of promoted slide feature and addition of specific image field
   on channel;

This merge is related to task ID 1936153 and closes PR #30985. More

Before this task, it was not easy to tell when a user is not available (or is on holiday)
from conversations, such as from chat windows.

With this task, a user can now tell that he is out-of-office from the user menu preferences,
by defining an an out-of-office message. This information will be displayed to other users from
chat conversations and mention suggestions (i.e. with `@`).

Also, the computation of the user `im_status` has been changed when he has an active leave:
an out-of-office message can be set on the leave, and this will be displayed on conversations
instead of the user's out-of-office message from the user menu preferences.

Task #1908673

Purpose
=======

The "invoice" modal is too complex to use for new users and has a lot of useless options for
the most simple use cases.

The goal here is to remove 2 options of the 'advance_payment_method' field:
* Invoiceable lines
* Invoiceable lines (deduct down payments)

And combine them into a new one: "Standard invoice".

If there are any down payments to deduct, another checkbox field appears under this
one: "Deduct down payments".

This keeps all the invoicing features while simplifying the modal.

Spec
=======
* Remove "invoiceable lines, deduct down payment" and replace by a checkbox
  (checked by default, only visible if down payments to deduct)
* Rename "Invoiceable lines" into "Standard invoice"
* tooltip on radio buttons: A standard invoice is issued with all the order lines ready for invoicing,
  according to their invoicing policy (based on ordered quantity or on delivered quantity).

Purpose of this commit is to clean a bit channel model. Promoted slide
feature is removed as people can already choose an order for a given
channel. Moreover promoted slide will not be used when having a eLearning
display of a channel.

Image field on channels is added as it is not depending on promoted slide
anymore.

To simplify future additions a search-specific template is removed to
have a unique template to display a channel content. It will ease future
merge.

This commit is linked to task ID 1936153 and PR #30985.

Purpose of this commit is to add some statistics computation on slide.channel
model. We want notably to have a count of views and votes (likes and dislikes)
on channels. Completion is also computed.

Purpose is to be able to search and order channels based on those statistics.
Having stored computed fields for some statistics help achieving that purpose.

Tests are added.

This commit is linked to task ID 1936153 and PR #30985.

Purpose is to be able to filter, search and categorize channels. Notably
with eLearning in mind there will be more channels as a channel will also be
used to hold lessons.

For that purpose we add a model of tag linked to channels. Those tags are
organized by groups in order to be able to display them using a menu or
a small hierarchy of tags. Displaying a tag group as a specific navigation
element is controlled by a specific field.

Those models will be used to display a new and improved home page for
channels / courses.

This commit is linked to task ID 1936153 and PR #30985.

`channel_info` can be called on multiple channels especially during
the init_messaging. The current implementation will perform read and
other queries in the loop. This commits aims to refactor `channel_info`
in order to read all informations in database out of the loop.

Computation of members informations is now the same as for `direct_partner`
As a side effect direct partner will have an email adress and members will have
im_status and out_of_office message if the partner is in a
channel of type chat. It would be easier to compute im_status in all case but
this could create performances issues when calling channel info on channel with
hundreds of users.

channel_fetch_preview will make a query in database in any case but seems to work ok
in api multi. We can put it out of the loop.

44ac7903 fix shouldn't be broken by this refactoring since we are no longer using the many2many to find direct_partners.

The IAP logo is an svg file, and contains a text tags with font
specified in it. It leads to wrong display in some browser and/or
operating systems when the font is not installed.

To avoid this wrong display we changed the text into a path in the svg.

Purpose
=======

The method named "action_invoice_create" in the sale_order model did not make sense:
  - this method is not an action (it returns the ids of created invoices)
  - it is not used as an action on any xml buttons
  - it has no reason to be private

This was probably a "real" action somewhere in the past but now it's just too confusing.

(The method in repair.order was also renamed for the same reasons).

Improve the User Interface of the Calendar mobile view.

- The "today" button should be aligned (both size and position) with the
view switcher icon.
- Extract mobile calendar styling into dedicated SCSS file.

This commit changes decorated many2many between slides and participants
recently introduced [1]. It was done between slide and users as people have to
login to have slide information.

Another many2many between channel and partners to store notably completion
and soon add statistics has been added [2]. It has been done between
channels and partners.

In this commit we choose to have the same relationship for slides, aka a link
between slides and partners. It allows to easily compute statistics and find
information based on partner_id.
