Adwords API get keywords with ruby on rails

Rails
1

Hello,

I took the ruby on rails example, and tried to add to it a view which is
displaying the keywords from an AdGroup, I am able to get the keywords,
and
the total no of keywords from a campaign but I don’t know why I can not
display them in the view.

keyword model:

class Keyword
attr_reader :id
attr_reader :criteriaType
attr_reader :keywordText

def initialize(api_campaign)
@id = api_campaign[:id]
@criteriaType = api_campaign[:criteriaType]
@keywordText = api_campaign[:keywordText]
end

def self.get_keywords_list(response)
result = {}
if response[:entries]
response[:entries].each do |api_keyword|
keyword = Keyword.new(api_keyword)
result[keyword.id] = keyword
end
end
return result
end
end

keyword_controller
class KeywordController < ApplicationController

PAGE_SIZE = 50

def index()
@selected_account = selected_account
if @selected_account
response = request_keywords_list(‘AdGroupID’)
if response
@keywords = Keyword.get_keywords_list(response)
@keyword_count = response[:total_num_entries]
end
end
end

private

def request_keywords_list(ad_group_id)
logger.debug ad_group_id
api = get_adwords_api()
service = api.service(:AdGroupCriterionService, get_api_version())
selector = {
:fields => [‘Id’, ‘CriteriaType’, ‘KeywordText’],
:ordering => [{:field => ‘Id’, :sort_order => ‘ASCENDING’}],
:predicates => [{:field => ‘AdGroupId’, :operator => ‘EQUALS’,
:values => [ad_group_id]},
{:field => ‘CriteriaType’, :operator => ‘EQUALS’, :values =>
[‘KEYWORD’]}],
:paging => {:start_index => 0, :number_results => PAGE_SIZE}
}
result = nil
begin
result = service.get(selector)
logger.debug 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
end
end

keyword/index.html.erb

Keywords list

<% if @selected_account.nil? %>

No account selected!

<% else %>

<% if @keywords.nil? or @keywords.empty? %>

  • No keywords available.

<% else %>
  • Total number of keywords: <%= @keyword_count %>




ID
 KeywordText
 CriteriaType
<% @keywords.each do |id, keyword| %>
<%= keyword.id %>
 <%= keyword.keywordText %>
 <%= keyword.criteriaType %> 
<% end %>
</table>

<% end %>

If someone can help me with some pointers, I’ll be grateful.

So I discovered what I did wrong,

def self.get_keywords_list(response)
result = {}
if response[:entries]
response[:entries].each do |api_keyword|
keyword = Keyword.new(api_keyword)
result[keyword.id] = keyword
end
end
return result
end

In my response loop I need to have something like
[keyword[:criterion][:id],
keyword[:criterion][:type],
keyword[:criterion][:text]]

but I am such a noob, that I don’t know how to implement that in my
code.

Thank you
