Rails JSON using RABL, showing parent attribute? - json

Question

I have the following RABL file in my Rails 3.2 application:
collection #results.limit(5)
attributes :date, :client_id
child :client do
attributes :Surname
end
child :animal do
attributes :AnimalName
end
I would like to add the name of the user that the result belongs to. Everything I have read in the RABL documentation seem to suggest that only child and node are available.
How could I get a parents attribute within the above code? Just doing the following returns NULL, obviously!
child :animal do
attributes :AnimalName
end
Is this possible?
Current JSON output:
{
date: "2013-06-25T19:36:11+01:00",
client_id: 88172,
client: {
Surname: "Strange"
},
animal: {
AnimalName: "Ria"
}
},
Desired output:
{
date: "2013-06-25T19:36:11+01:00",
client_id: 882372,
client: {
Surname: "Summer"
},
animal: {
AnimalName: "Ria"
},
user: {
UserName: "Danny"
}
},

Answer 1

You can add a custom node that adds in the user data:
collection #results.limit(5)
attributes :date, :client_id
node :user do |report|
partial('users/show', :object => report.user)
end
This is assuming that you want the whole user/show template.
If you just want the name key/value:
node :user do |report|
{ :name => report.user.name }
end
