Re: Warning about creating a product and reusing its variable
Ooh, thanks for that warning.
I would have said bug for the resulting recordset to have context values left over from its own needs...
Good luck getting that sorted, though, without proposing the fix yourself....
Cheers

Subject: Warning about creating a product and reusing its variable
Hi everyone,
A small tip to avoid an headache :
If you create a new product
item_a = self.env["product.product"].create({"name": "ItemA"})
And then copy it
item_b = item_a.copy({"name": "ItemB"})
You will have the surprise to see that "item_b" is en empty recordset.
Why ? Simply because a context key is set by odoo (create_product_product=False) when creating a `product.product`
So to avoid this issue, simply re-browse your newly created record to have a clean context:
item_a = self.env["product.product"].create({"name": "ItemA"})
item_a = self.env["product.product"].browse(item_a.id)
item_b = item_a.copy({"name": "ItemB"})
item_a = self.env["product.product"].browse(item_a.id)
item_b = item_a.copy({"name": "ItemB"})
I don't know if it should be considered a bug or not but I believe that if a context key is set from create/copy/etc. to fix some recursion issue, the context should be cleaned after
super() before returning the final value

Re: Warning about creating a product and reusing its variable
I finally made a PR about this issue but without being sure that the fix is the way to go.--
