Extend column_for_attribute to work with form helpers (simple_form, etc)

[peck]

Any interest in adding this to the gem itself? I find myself using using the following function in my models that I pass into simple_form builders to have the fields show up as the correct type, and not just default to text after receiving nil.

    def column_for_attribute(attr)
     atr = hstore_metadata_for_properties[attr]
     if attr
       OpenStruct.new(type: atr)
     else
       super(attr)
     end
    end

This seems useful. Can you create a PR with some tests?

[peck]

Will do, have to work through some things downstream in the process for updating attributes and making sure all is good there, but yes, Ill put it on my to-do list and see what I can come up with.

Shouldn't use OpenStruct here, just create a regular Struct somewhere to avoid method cache busting every time an hstore class is used in a form build.

[jhirn]

+1 for no OpenStruct. In fact, it should respect the original return type of column_for_attribute as closely as possible. While Struct/OpenStruct might meet the needs of simple_form, it could be surprising to someone expecting a different object.

@peck, are you still hacking on this?
