I am currently testing some code from google adwords ruby api.
class CampaignController < ApplicationController
PAGE_SIZE = 50
def index()
@selected_account = selected_account
if @selected_account
response = request_campaigns_list()
if response
@campaigns = Campaign.get_campaigns_list(response)
@campaign_count = response[:total_num_entries]
end
end
end
private
def request_campaigns_list()
api = get_adwords_api()
service = api.service(:CampaignService, get_api_version())
selector = {
:fields => ['Id', 'Name', 'Status'],
:ordering => [{:field => 'Id', :sort_order => 'ASCENDING'}],
:paging => {:start_index => 0, :number_results => PAGE_SIZE}
}
result = nil
begin
result = service.get(selector)
rescue AdwordsApi::Errors::ApiException => e
logger.fatal("Exception occurred: %s\n%s" % [e.to_s, e.message])
flash.now[:alert] =
'API request failed with an error, see logs for details'
end
return result
endend
class Campaign
attr_reader :id
attr_reader :name
attr_reader :status
def initialize(api_campaign)
@id = api_campaign[:id]
@name = api_campaign[:name]
@status = api_campaign[:status]
end
def self.get_campaigns_list(response)
result = {}
if response[:entries]
response[:entries].each do |api_campaign|
campaign = Campaign.new(api_campaign)
result[campaign.id] = campaign
end
end
return result
endend
What I want to do is take the value of @campaign_count (from the
controller) and save it in a db. I tried adding the code for inserting the
value in the db, but it says that I'm missing few parameters. I want to
save this value because I want to display it in application.html.erb, or
otherwise I will have to request data from the api every time I load a page.
Campaign.create(:total_campaigns => 2)
Thank you.
