The button to skip an operation is only implemented for the pick
operation (not for the put or for the inventory ones) but it was
shown in the screens for all the operations, yielding to a stack
trace when it was pressed from the wrong operationg. The button
has been moved now to the screen for the pick operation, only.
In the screen for the vertical lift shuttles, accessible through
Inventory > Operations > Vertical Lift Shuttles, a new button has been
added to allow to skip an operation. This button can also be triggered
by scanning the barcode O-BTN.skip.svg that is inside the folder
'images'.
When a skip is done, the next stock.move.line to pick is chosen and
shown to the operator. A skipped move line is added to the end of the
list of pending move lines to be picked, so they will be shown again
in the future as soon as the other move lines have been successfully
processed.
This option was added because, sometimes, the operator can not process
a move line for whatever reason. Right now, the only way of proceeding
is to wait until he/she can effectively process it, which involves a
delay in the operations. With this new skip operation, the operator
can continue processing the rest of move lines.
If there is two move lines for the same product in the vertical lift
(stored in2 differents trays for instance), the pick scenario was
failing when the user was processing the first line.
To circumvent this, instead of validating directly the move, we put the line
in its own stock move, then we put the stock move in its own transfer and
validate this one.
Methods used to do that have been copied from the `shopfloor` module,
they probably deserves their own module as they are quite generic.
If we have several goods to put in the same tray, it is inefficient to
release (close) the tray between each line if we reopen the same tray.
Release the tray only when the last line is reached.
There is no such action as 'ir.actions.do_nothing', it kinda works,
until you look into the js console and stares at the errors.
There is a nice OCA module that serves this purpose (more or less,
because it reloads the window, this is not an issue).
Namely, the pick/put/inventory operations are now split in
different models.
Pick and Put share a model and customize their behavior, which is pretty
similar. The inventory operation will have a different view and
different workflow.
This changes will ease a lot the customization of the different
workflows and views.
* Add vertical_lift_shuttle_id field on stock.location, help to find the
shuttle for a location
* Add StockLocation.fetch_vertical_lift_tray(), that needs to be
implemented in addons to send commands to the hardward to fetch a tray,
and if existing show a cell (laser pointer, ...)
* Add helpers on stock.move.line fetch_vertical_lift_tray_source() and
fetch_vertical_lift_tray_dest() that fetch the tray directly from a move
line's source or destination location
