Indifferent access for array of hashes

[23tux]

Hi,

I have the following model:

class Run
  include Mongoid::Document
  include Mongoid::Extensions::Hash::IndifferentAccess

  field :results, type: Array, default: []
end

I'm storing hashes inside the :results array. Is it possible to have indifferent access here? For example, when I try to

Run.create! results: [{foo: "bar"}]
Run.first.results.first[:foo] # is nil, doesn't work
Run.first.results.first["foo"] # is "bar", works

[mindscratch]

Perhaps, although I'm a little skeptical because of having to interrogate the values of a field (i.e. look into an array and make each element a Hash with indifferent access if its a regular Hash to begin with).

You probably already know, but just to be explicity you could do:

Run.first.results.first.with_indifferent_access[:foo]

It's a bit more verbose, but still gets the job done.

I am in need of this feature, too. It would be consequent to apply this to arrays as well. Obviously, as you pointed out @mindscratch it can be done manually, but I do not see the point if it cannot be delegated to the model which is supposed to support this. Hashes and Arrays belong together.

My initials thoughts are that I'd have to check for Array fields and enhance the Array so as you access the elements in it I could check if the element was a Hash, then turn it into a hash with indifferent access. I'm not a fan of that, do either of you (@platzhirsch or @23tux) have ideas? I'm open to pull requests 😺
