Array types are possible

[mhenrixon]

I was using my own hacked together solution until rails 4.2 arrived the file can be found here -> https://gist.github.com/mhenrixon/8fb6f1b8dfbd74d2f734

Allows for 2 custom types to be saved just joining and splitting on a character most likely unused for string and integer arrays

# read value from store
when :string_array then
  value.split('|')
when :int_array then
  value.split('|').map(&:to_i)

# write value to store
value = value.map(&:to_s).join('|') if value.is_a?(Array)

I haven't found a better solution than mine until I stumbled on typedstore. Happy to help if you are interested in supporting arrays as well if not I'll keep working on my own stuff.

What if one of the strings in the array contain a |? You need to escape etc. You might as well serialize to JSON or YAML. And then you can't query it anymore, so you might as well use a blob column.

I prefer not to implement features that would have such limitations. Even more since I beleive you can do it with a custom encoder.

But thanks for the heads up.

No problem at all, I'll just work on my own thing then.
