Hi everyone,
I'm trying to update attributes in a collection passed to form_tag.
However my syntax for extracting values from the params hash results
in this exception:
undefined method `keys' for ["Vanilla", "Rose", "Cranberry"]:Array
So it appears I am trying to call keys on an array of "flavor"
attribute values, rather than extracting "Candle" object id keys from
the params hash. I have included the code from the view and controller
below.
Thanks for taking the time to read this. I appreciate any specific
suggestions, as well as any resources that explain the intricacies of
params.
Thank You!
