rails jbuilder getting Called id for nil -

i'm trying utilize jbuilder gem format json output.

controller

class locationscontroller < applicationcontroller def tree @locations = location.all end

tree.json.jbuilder

jbuilder.encode |json| json.id @location.id json.name @location.name end

test using url:

http://localhost:5000/locations/tree.json

results:

called id nil, mistakenly 4 -- if wanted id of nil, utilize object_id extracted source (around line #2): 1: jbuilder.encode |json| 2: json.id @location.id 3: json.name @location.name 4: end

you don't seem define @location in code have posted. should iterate on locations, jbuilder lets illustration this:

jbuilder.encode |json| json.locations @locations |location| json.id location.id json.name location.name end end

see docs if want flat array instead.
