How Can I Get An Enum's String Value Dynamically?

Question

I have a Video model with a property called aspect_ratio that is an enum:

ASPECT_RATIOS = [:four_three, :sixteen_nine]

enum aspect_ratio: ASPECT_RATIOS

The property is stored as an integer.

When I access this property, I get a string representation of the enumerated symbol

video.aspect_ratio # four_three
video.aspect_ratio.class # String

However when I iterate over the model's properties using video.attributes.each_pairthe value of aspect_ratio is an integer. I need to iterate over attributes in such a way that if the attribute is an enum I get the string value, not its integer value.

The following also return its integer value:

video.read_attribute(:aspect_ratio)
video[:aspect_ratio]

Is there another way to iterate to ensure I get the string value of the enum?

Answer 1

you could try the easiest way: video.public_send(:aspect_ratio)
