I have the following ActiveModel serializer which parses the following data:
class CarSerializer < ActiveModel::Serializer
attributes :brand, :wheels, :events
def brand
{ id: object.id, brand_name: object.brand_name }
end
def wheels
object.wheel_details
end
def events
object.car_events
end
end
and the following is the data shows up:
{
"car_info": [
{
"car": {
"id": 1,
"brand_name": "opel"
},
"wheels": [
{
"id": 2,
"size": "23.4"
},
{
"id": 1,
"size": "22.3"
}
],
"events": [
{
"id": 1,
"event_place": "america"
},
{
"id": 1,
"event_place": "asia"
}
]
However, i want the data to look like the following:
{
"car_info": [
{
"car": {
"id": 1,
"brand_name": "opel"
},
"wheels_and_events": [
{
"id": 2,
"size": "23.4"
"event_place": "america"
},
{
"id": 1,
"size": "22.3"
"event_place": "asia"
}
]
I'm using has_many through associations for 3 tables and one table for the relation.

I run
Post.search("daniel")
I get 60+ results
Post.where(archive: true)
I get 60+ results
Post.search("daniel", where: { archive: true }

I get 0 results

I looked at the searchkick gem doc and I am following exactly what they have listed to do. The normal search works fine and it only returns 0 posts when I add the where clause.
Without the where clause it shows all the posts which have "daniel" in the and it breaks when the where clause is added.
What am I doing wrong here? Is more information needed?
require 'elasticsearch/model'
class Post < ApplicationRecord
searchkick text_start: [:title]
I have a few conditions where don't want to serialize the current object and want to skip it. But i haven't found a way to do that so I am ignoring attributes on attribute :foo, if: :condition. And this is generating empty {} in my serialized object inside arrays. How do I fix this?

serializer looks something like this-
class BoardSerializer < ActiveModel::Serializer
#some code
class GradeSerializer < ActiveModel::Serializer
has_many :subjects
#some code
class SubjectSerializer < ActiveModel::Serializer
attribute :id, if: :condition
attribute :name, key: :subject, if: :condition
def condition
#some code
#returns true or false
#will not return both :id and :subject if false- I want to
#skip this current object if condition fails. (returns {})
end
end
end
end
How do I simply skip the current object in the serializer or remove empty hashes? Thanks
Please, check if this is the expected result:
input.transform_values { |v| v.map {|e| e.transform_values { |vv| vv.class == Array ? vv.select { |ee| ee unless ee.empty? } : vv } } }
# => {:grades=>[{:id=>333938, :name=>"1", :subjects=>[{:id=>571671, :subject=>"Math"}, {:id=>742980, :subject=>"Science"}, {:id=>186926, :subject=>"English"}, {:id=>658224, :subject=>"Social_Studies"}]}]}
EDIT: to meet changes in OP question.
input.map { |e| e.transform_values { |v| v.is_a?(Array) ? v.map {|ee| ee.transform_values { |vv| vv.is_a?(Array) ? vv.select { |eee| eee unless eee.empty? } : vv } } : v } }
# => [{:id=>392027, :name=>"ISC Board", :grades=>[{:id=>333938, :name=>"1", :subjects=>[{:id=>571671, :subject=>"Math"}, {:id=>742980, :subject=>"Science"}, {:id=>186926, :subject=>"English"}, {:id=>658224, :subject=>"Social_Studies"}]}, {:id=>333943, :name=>"2", :subjects=>[{:id=>571671, :subject=>"Math"}, {:id=>742980, :subject=>"Science"}, {:id=>186926, :subject=>"English"}, {:id=>658224, :subject=>"Social_Studies"}]}]}, {:id=>666627, :name=>"NY Board", :grades=>[{:id=>333938, :name=>"1", :subjects=>[{:id=>571671, :subject=>"Math"}, {:id=>742980, :subject=>"Science"}, {:id=>186926, :subject=>"English"}, {:id=>658224, :subject=>"Social_Studies"}]}, {:id=>432943, :name=>"2", :subjects=>[{:id=>571671, :subject=>"Math"}, {:id=>742980, :subject=>"Science"}, {:id=>186926, :subject=>"English"}, {:id=>658224, :subject=>"Social_Studies"}]}]}]
You can use #select! for this matter:
input = {
"grades":
[
{
"id": 333938,
"name": "1",
"subjects":
[
{
"id": 571671,
"subject": "Math"
},
{
"id": 742980,
"subject": "Science"
},
{
"id": 186926,
"subject": "English"
},
{
"id": 658224,
"subject": "Social_Studies"
},
{},
{},
{}
]
}
]
}
input[:grades].first[:subjects].select! { |i| !i.empty? }
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
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
I have two models related :
class Item < ActiveRecord::Base
belongs_to :carousel
end
And
class Carousel < ActiveRecord::Base
has_many :items
end
I trying to open API to carousels using the JSON API Resources gem, i need to show carousel attributes and some items attributes, something like this:
{
"data": [
{
"id": "1",
"type": "carousels",
"links": {
"self": "http://localhost:3000/api/v1/carousels/1"
},
"attributes": {
"name": "primary",
"items": [
{
"title": "first item",
"file-url": "url",
"index": 0
},
{
"title": "second item",
"file-url": "url",
"index": 1
}
]
}
}
]
}
My carousel resource:
module Api
module V1
class CarouselResource < JSONAPI::Resource
immutable
attributes :name, :items
def self.records(options = {})
user = options[:context][:current_user]
user.carousels
end
end
end
end
My result:
{
"data": [
{
"id": "1",
"type": "carousels",
"links": {
"self": "http://localhost:3000/api/v1/carousels/1"
},
"attributes": {
"name": "primary",
"items": [
{
"id": 3,
"carousel_id": 1,
"file": {
"url": "url"
},
"title": "first item",
"kind": 0,
"index": 0,
"created_at": "2017-02-23T10:31:53.592-03:00",
"updated_at": "2017-03-01T10:30:52.533-03:00"
},
{
"id": 5,
"carousel_id": 1,
"file": {
"url": "url"
},
"title": "second item",
"kind": 0,
"index": 1,
"created_at": "2017-03-01T10:30:07.011-03:00",
"updated_at": "2017-03-01T10:30:07.011-03:00"
}
]
}
}
]
}
I'm attempting to take a JSON API response, with nested associated resources, and reverse the associations in a Rails app.
So, imagine I get a response like this:
{
"spenders": [
{
"id": 1,
"name": "John Doe",
"accounts": [
{
"id": 1,
"name": "Account One"
},
{
"id": 2,
"name": "Account Two"
}
]
},
{
"id": 2,
"name": "Jane Doe",
"accounts": [
{
"id": 1,
"name": "Account One"
},
{
"id": 3,
"name": "Account Three"
}
]
}
]
}
My goal is to convert this into structure like this:
{
"accounts": [
{
"id": 1,
"name": "Account One",
"spenders": [
{
"id": 1,
"name": "Stephen Margheim"
},
{
"id": 2,
"name": "Greg Barendt"
}
]
},
{
"id": 2,
"name": "Account Two",
"spenders": [
{
"id": 1,
"name": "Stephen Margheim"
}
]
},
{
"id": 3,
"name": "Account Three",
"spenders": [
{
"id": 2,
"name": "Greg Barendt"
}
]
}
]
}
Now, I can do this fairly well with iteration over the hash and building a new hash:
spenders_hash = {}
accounts.each do |account|
account.spenders.each do |spender|
if spenders_hash.key? spender.id
spenders_hash[spender.id][:accounts] << account
else
spenders_hash[spender.id] = hash_from_spender_and_account(spender, account)
end
end
end
spenders_hash
def hash_from_spender_and_account(spender, account)
{
id: spender.id,
name: spender.name,
accounts: [account],
}
end
I'm hoping to find [1] a more flexible solution that isn't reliant on knowing the key names in advance and [2] hopefully more efficient.
Thoughts?
