Ruby on Rails parse api to save to db - ruby-on-rails

Question

I am practicing with apis in RoR. I am trying to save only a few items from the api call id, length, dip, name but how do I parse it and save the fields that I need and do they need to be in params? Currently the api call data is not in params.
On button click I want to have those fields listed above save into the db
routes
root 'welcome#index'
post 'search_campaigns', to: 'campaigns#search_all_campaigns'
my model
class Campaign < ApplicationRecord
def self.get_your_campaigns
uri = URI.parse("https://example.site/api/v2/users")
request = Net::HTTP::Get.new(uri)
request.content_type = "application/json"
request.basic_auth("example#email.com", "238urfs393kmdsb2189aead01")
req_options = {
use_ssl: uri.scheme == "https",
}
response = Net::HTTP.start(uri.hostname, uri.port, req_options) do |http|
http.request(request)
end
return JSON.parse(response.body)
end
end
controller
class CampaignsController < ApplicationController
def search_all_campaigns
#campaigns = Campaign.get_your_campaigns
redirect_to root_path
end
end
view
<%= button_to 'Get All Campaigns', search_campaigns_path %>
This how the api call data looks
[{"id"=>2758, "dip"=>"2.0", "length"=>10, "name"=>"Cereal", "total_remaining"=>100, "status"=>6, "is_retarget"=>false}, {"id"=>278563, "dip"=>"1.25", "length"=>2, "name"=>"Pizza", "total_remaining"=>123, "status"=>6, "supplier_link"=>"http://www.developingmedia.com/adhoc.php?id=", "incidence"=>50, , "days_in_field"=>5, "max_daily_completes"=>nil, "is_retarget"=>false}, {"id"=>278564, "dip"=>"4.25", "length"=>25, "name"=>"California", "days_in_field"=>5,}]

Answer 1

You say the API and therefore you Campaign.get_your_campaigns method returns a Hashthat looks like this:
[
{
"id" => 2758,
"dip" => "2.0",
"length" => 10,
"name" => "Cereal",
"total_remaining" => 100,
"status" => 6,
"is_retarget" => false
},
{
"id" => 278563,
"dip" => "1.25",
"length" => 2,
"name" => "Pizza",
"total_remaining" => 123,
"status" => 6,
"supplier_link" => "http://www.developingmedia.com/adhoc.php?id=",
"incidence" => 50, ,
"days_in_field" => 5,
"max_daily_completes" => nil,
"is_retarget" => false
},
{
"id" => 278564,
"dip" => "4.25",
"length" => 25,
"name" => "California",
"days_in_field" => 5,
}
]
You can use Hash#slice to extract only the attributes you are interested in. And then pass those attributes one after the other to the create method:
campaigns_hashes = Campaign.get_your_campaigns
campaigns_attributes = campaigns_hashes.map { |hash| hash.slice(:id, :name, :length, :dip) }
campaigns = campaigns_attributes.each { |attributes| Campaign.create(attributes) }
Note: You will very likely need to add some error handling to this, for example, to deal with invalid data returned from the API or the handle records that have already been imported to avoid duplicates.
