Errors.each_key throws undefined method error

I’m trying to create custom error messages and in doing so I thought I
could access the validation errors each_key method. I know each_key
isn’t listed as a method for errors object but errors object is a hash
right? When I look at the source of each method

def each
@errors.each_key { |attr| @errors[attr].each { |msg| yield attr, msg }
}
end

each_key is being used but when I access it directly, it barfed with
undefined method error. Anyone knows why? Thanks in advance for your
help.

@errors is an instance variable on the model - I doubt you’re
accessing that from the controller…

I’m also not clear what’s wrong with @model.errors.each - it gets you
exactly the same results as iterating with each_key on the underlying
array…

There isn’t anything wrong with @model.errors.each, I was experimenting
with different ways to get at the unique keys since there may be more
than 1 error message per key (field). I ended up creating a local hash
variable to get the functionality I want. Thanks for your insight.
