How to merge a JSON-object in Jbuilder - ruby-on-rails

Question

I am creating a rails app with Backbone/Marionette frontend.
I want to take the JSON-object below and transform it.
This is how it looks now
[{
"total_entries": 4
},
{
"entries": [{
"user": {
"id": 1,
"fullname": "Paul Paulsen"
},
"reports": [{
"id": 1,
"name": "Anna Pearson",
"relation": "wife",
"phone": "2232",
"email": "adsas#sss.se"
}
]
},
{
"user": {
"id": 2,
"fullname": "Anna Palmgren"
},
"reports": [{
"id": 3,
"name": "Mika",
"relation": "Andersen",
"phone": "12312321",
"email": "aas#sss.se"
}]
}
]
}
]
I want to make it look like this
[{
"total_entries": 4
},
{
"entries": [{
"id": 1,
"fullname": "Paul Paulsen"
}, {
"id": 1,
"name": "Anna Pearson",
"relation": "wife",
"phone": "2232",
"email": "adsas#sss.se"
}, {
"id": 1,
"fullname": "Anna Palmgren"
}, {
"id": 3,
"name": "Mika",
"relation": "Andersen",
"phone": "12312321",
"email": "aas#sss.se"
}
]
}
]
This is the Rabl file/code I use
json.array! [0,1] do |index|
if index == 0
json.total_entries #total
else
json.entries #reports.group_by(&:user) do |user, reports|
json.user user, :id, :fullname
json.reports reports do |report|
json.extract! report, :id, :name, :relation, :phone, :email
end
end
end
end

Answer 1

Try this ruby snippet.
x= [{
"total_entries": 4
},
{
"entries": [{
"user": {
"id": 1,
"fullname": "Paul Paulsen"
},
"reports": [{
"id": 1,
"name": "Anna Pearson",
"relation": "wife",
"phone": "2232",
"email": "adsas#sss.se"
}
]
},
{
"user": {
"id": 2,
"fullname": "Anna Palmgren"
},
"reports": [{
"id": 3,
"name": "Mika",
"relation": "Andersen",
"phone": "12312321",
"email": "aas#sss.se"
}]
}
]
}
]
x[1][:entries] = x[1][:entries].map{|p| [p[:user], p[:reports]]}.flatten
