json - Rabl / Will Paginate setting name of root child -

i wonder if can help. i'm trying migrate our old rails model#to_json our api make versioning easier in longer term. i'm struggling @ first hurdle because of rabl , paginate.

we override willpaginate::collection#as_json

module willpaginate   class collection      alias :as_json_without_paginate :as_json         def as_json(options = {})        # rabl seemingly passing json::ext::generator::state as_json       unless options.is_a?(hash)         options = {}       end        json = {         :page => current_page         :per_page => per_page,         :total_entries => total_entries,         :entries => as_json_without_paginate(options)       }     end    end end 

so @collection.to_json return like

{   "total_entries": 1,   "page": 1,   "entries": [     {       "follow": {       "id": 1,       "name": "test"       }     }   ],   "per_page": 10 } 

however when try following in rabl

node(:page) {|m| @follows.current_page } node(:per_page) {|m| @follows.per_page } node(:total_entries) {|m| @follows.total_entries}  child(@follows => :entries)   # extends 'follows/show'   attributes :id, :name end 

the name of child automatically set 'entry', want set 'follow' consistent our current api having no luck whatsoever.

{   "total_entries": 1,   "page": 1,   "entries": [     {       "entry": {       "id": 1,       "name": "test"       }     }   ],   "per_page": 10 } 

can give me pointers. i've been trying trace through source , seems name of root object name child implied.

i've encountered same exact bug, problem seems setting object_root false. here same solution proposed in response stackoverflow question: wrong child root name in rabl , can't set child root name

child( {@follow => :entries}, {:object_root => false} )    # extends 'follows/show'    attributes :id, :name end 

note both round parentheses "()" , braces "{}".

hope helps. worked in case.
