initial site
modify the discontinued attribute of all the products in one breath modifying index view of the product action
select which products to update an update them in one step
redisplay the edit_multiple form only with the invalid products if some products failed to update
another approach is to craft a form with a single set of fields to modify attributes of multiple products to the same values in one straw
now we have the ability to select no discontinued value and no category value if we don't want to change them, in previous instance these attributes were modified every time
catch error validation in the edit multiple form, but we lost all data we send to the form
persist the data we send to the form if some products failed to update
edit the price attribute relatively for example -20%
