Oh, I see -- the "extra" quotes and backslashes are the output of =
inspect. Note the difference in irb:

2.0.0-p247 :013 >=20
The second one is the actual value of TECHS.
Let's take another stab at this.
TECHS is a hash with only one key: 'platform':
2.0.0-p247 :019 > TECHS.class
=3D> Hash=20
2.0.0-p247 :020 > TECHS.keys
=3D> ["platform"]=20
which contains an array of 1 item:
2.0.0-p247 :021 > TECHS['platform']
=3D> [{"AssignedName"=3D>"P1", "ExportPrice"=3D>"USD", "Id"=3D>"1", =
"Delivery"=3D>"Y", "RegisteredMembers"=3D>[{"Name"=3D>"Admin", =
"Id"=3D>"3", "AvailablePosts"=3D>[{"Seat"=3D>"2", "Colour"=3D>18}, =
{"Seat"=3D>"3", "Colour"=3D>19}, {"Seat"=3D>"4", "Colour"=3D>181}, =
{"Seat"=3D>"5", "Colour"=3D>183}]}]}]=20
2.0.0-p247 :022 > TECHS['platform'].class
=3D> Array=20
2.0.0-p247 :023 > TECHS['platform'].count
=3D> 1=20
That one item is the thing you actually want to convert to pass to you =
model, yes? So without all the hoopla, try:
2.0.0-p247 :027 > params =3D Hash[TECHS['platform'].first.map{|k,v| =
[ActiveSupport::Inflector.underscore(k.to_s),v]}]
=3D> {"assigned_name"=3D>"P1", "export_price"=3D>"USD", "id"=3D>"1", =
"delivery"=3D>"Y", "registered_members"=3D>[{"Name"=3D>"Admin", =
"Id"=3D>"3", "AvailablePosts"=3D>[{"Seat"=3D>"2", "Colour"=3D>18}, =
{"Seat"=3D>"3", "Colour"=3D>19}, {"Seat"=3D>"4", "Colour"=3D>181}, =
{"Seat"=3D>"5", "Colour"=3D>183}]}]}=20
I'm not sure what you want to be doing with the registered_members =
value, and the AvailablePosts key underneath that. Are these nested =
parameters for going in other tables with relationships? If so, you'll =
need to run those through the same method above. It would probably be =
very worthwhile to make that an actual method, that could be called =
recursively if v is something you want to work on (Hash, Array, Object).
