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
<h1>Keywords list</h1>
<% if @selected_account.nil? %>
<div class="notice">No account selected!</div>
<% else %>
<% if @keywords.nil? or @keywords.empty? %>
<ul><li>No keywords available.</ul>
<% else %>
<ul><li>Total number of keywords: <%= @keyword_count %></ul>
<table>
<tr>
<th>ID
<th>KeywordText
<th>CriteriaType
<% @keywords.each do |id, keyword| %>
<tr>
<td><%= keyword.id %>
<td><%= keyword.keywordText %>
<td><%= keyword.criteriaType %>
<% end %>
</table>
<% end %>
If someone can help me with some pointers, I'll be grateful.
Thank you
