Hey guys,
I have a situation where I'm creating a object which have some items and
the items have a validation that need to be executed on the server side but
rails do not map these validation messages to the specific child.
A contrived example may be a invoice which have 2 items and for some reason
the product of one of these items is not allowed to be inserted:
POST
/invoices?invoice[items_attributes][0][product_id]=1&invoice[items_attributes][1][product_id]=2
The JSON response when the validation fails is something like:
{"items.product":["is not allowed"]}
But for which item the validation failed? For this JSON response, I can't
guess if it was the first or the second nor both items.
I was thinking in something like:
{"items.1.product":["is not allowed"]}
Where the 1 is the child index (can't use the id because we do not have it
for new records).
That's a proposal but we may implement something else.
Suggestions?
