how parse these data in ror using json how write parsing json file these data,how one

there many ways:

1. create method to_json each model

2. create view named, i.e. hotels/index.json.erb , write json code using erb templating engine

   [   <% @hotels.each |hotel| %>     { 'id': <%= hotel.id %>, 'name': "<%= hotel.name %>" },   <% end %> ] 

3. use library jbuilder (on bottom of page list of alternatives jbuilder)

   # hotels/index.json.jbuilder json.array!(@hotels) |hotel|   json.id hotel.id   json.name hotel.name end
