When you execute the slug method on a virtual record (not yet
saved, virtualid/newid) the slugs obviously fails as it needs
an id and a display_name.

This issue happens when there's a depends on a function field
using the slug method: just after the create and during the
onchanges, they'll raise.

This patch makes the slug method returns None in these case,
anyway the depends are re-triggered after the write and at
this time they have an id and everything is working fine.

Stock account is sufficient for Point of Sale. No need to set sale_stock as
dependency, as it installs Sales Management but is not required for running
the POS.

This commits adds the check W0101 to test_pylint and fixes the errors.

The index in sequence.py was added in rev 1381ac13 and cancelled a day later in 83fdc271
so i guess it is safe to remove it.

A new field `create_variant` has been added on `product.attribute`.
If unchecked, the attribute will not create variant.

These attributes will be added on the sale order description if bought from the shop.
The lines of a product with these attributes will be splitted to keep the description.

Fp request: In the user preferences menu, remove "About Us" and put the version number in the Settings dashboard somewhere, as well as the link to switch to developer mode. Odoo is not a desktop application anymore.

For the need of the next commit, we have to know when making a request from an RPC call in which debug mode we are. Previously, the value was always 'true' if we were in debug mode. Now it will return 'true' if we are in simple debug mode and 'assets' if we are in the other one. (this is the current behavior for the simple WebRequest).

Why do we need to know that? When loading the settings dashboard, an rpc request to /web/dataset/call_kw to load the view is accessing the odoo.debug @property method. This value is used in the template to decide which buttons to display to activate or deactivate the debug mode.

Specifications
==============

Add an option in the settings to use the surveys or not
By default : do not use interview forms.
If the option is false : on the job application, hide the Interview form field

A ticket whose seats_availability is unlimited,  is not shown on saleorder line. Fixed it.
It should show all the ticket whose seats_availability is unlimited or seats_available is greater than 0.

========
Purpose
========

The graphs on the accounting dashboard give the impression that we had $0 in the bank because the graph is at the bottom of the kanban kard.

==========
Specification
==========

The bottom should be zero, the top should be the maximum of the visible period, and the rest of the graph should be proportionate.

=======
PURPOSE
=======

In list view, when handling in mass the opportunities and mark it as lost, it
should be possible to set the lost reason.

The reason would be the same for all the selected opportunities.

=============
SPECIFICATION
=============

On clicking of 'Mark as Lost', ask user the lost reason through wizard. and then
set that lost reason to all the opportunities selected.

[IMP] website: better dialog when clicking on a menu in edit mode
	(less options is easier)

Show number of members found in the searchbox

Task 20251

Now you have the option to show the number of product found after one search.

Now you can sort products by lst_price, name, ... via the UI

In some case the price list or b2b/b2c mode can altered the price
and the sort on lst_price can be sometimes wrong.
Eg: if price is displayed vat in (b2c), and mix rate of 6% and 21%, the sort
will be done on the htva price.

Before this commit, if a partner was NOT company, but have 1 or more
contacts (delivery, invoice, ...), the nameget of the contact was empty.

Now we display the "<parent partner name>, <type contact>"

* web_editor, website, mass_mailing

This menu allowed to scroll to the snippets sections by clicking on
their corresponding icons. It was useless as the sections are not
taking a lot of height. This also appeared buggy as clicking on the
last icon highlighted only the second one as this second one was still
the first section visible on the screen when the last section was
fully visible.

This also added fours buttons to the interface which contains already a
lot of them. Now this is replaced by a title "Add blocks" which makes
the editor cleaner and also improved the performance to enter the edit
mode.

* Isolate website_blog style
* Simplify/Correct the cover option JS
* Allow to modify the cover from the blog list page
* Change cover layout (use a more conventionnal odoo design with a
div which is full width, which contains a container(-fluid) then its
content) -> easier to customize.
* Refactore code to be understandable
* Change behavior of opacity filter: before this commit the cover
filter was not intuitive and did not work on IE or Edge, it mixed
the color of the bg-image and the bg-color in a complex way and the
opacity was just controlling if the image was visible clearly or not
(which led in general to ugly style if the opacity was used). Now, the
color in applied *on top* of the image so that its color changes the
hue of the underlying image. The opacity value controls only the
opacity value of the color to mix.

[MIGRATION] Note: as the opacity behavior has changed, the exact same
behavior is not reproductible at all. But for the change to make a bit
of sense in old databases, this should be applied for the field
"cover_properties" of blog posts (with changes in layout):

if cover_properties.background-color != "oe_none":
    cover_properties.opacity = 0.6
else:
    cover_properties.opacity = 1.0 - cover_properties.opacity

It is better because it then proposes to add a page, a product, a blog,
a forum, a job offer, ... (not only a page).

Splitting the summernote colorpicker into bg colorpicker and foreground
colorpicker seems to have been a bad idea as people tend to click on
the recent color button thinking it will open a dropdown.

This commit keeps the design that had been decided for colorpicker
template and do not change the "background-color" snippet option.
However, the colors for background and foreground text changes are
now displayed in an unique dropdown again, with reviewed style.
