How to use Tracking Key in DD4T application

Question

I am doing a POC for Personalization in DD4T, where I want to store the information of the Pages, and Components visited and to fill the Tracking_Keys table for a session user. I want to use this data to personalize the content.

I am using the below code to store the Keys

//For tracking the page and component visits           
var waiPage = new WAIPage(pgModel.Id, this.HttpContext.ApplicationInstance.Context); 
//For Storing the Tracking Key
Tridion.ContentDelivery.Web.WAI.TrackingKeys trackingKey = new TrackingKeys(waiPage.User);
trackingKey.IncrementKey(keyword);
trackingKey.SetKey(keyword, 8);
trackingKey.ExecuteUpdate();

The cd_wai_conf.xml is below here

 <?xml version="1.0" encoding="UTF-8"?>
  <Configuration Version="7.1"  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="schemas/cd_wai_conf.xsd">  
<Global>    
</Global>  
<Presentations>   
<Presentation Id="1">     
  <Host Domain="localhost" Port="3035" Protocol="http" Path="/"/>      
  <Personalization Enabled="true" Persistence="cookies">       
    <Cookie Name="TDS1234" Expires="39000"/>
    <Tracking>          
      <Timeframe Type="hourly" Multiplier="1" Autofill="true"/>          
      <Pages Enabled="true"/>         
      <Components Enabled="true" Max="10" Averaging="true"/>         
      <ComponentLinks Enabled="true"/>
      <Keys Enabled="true" Increment="50" Decrement="1" Averaging="false" ComponentLinks="true"/>          
      <Exclude>            
        <Pages></Pages>            
        <Components/>           
        <Paths/>
      </Exclude>
    </Tracking>        
    <CustomerCharacteristics PreserveWhitespace="true"/>
  </Personalization>
</Presentation>
</Presentations>
</Configuration>

Also I have added the entry in to the cd_storage_config.xml

<ItemTypes defaultStorageId="defaultdb" cached="false">
  <Item typeMapping="Personalization" cached="false" storageId="defaultdb"/>
</ItemTypes>

With this configuration whenever I am requesting a page, the Page and the corresponding Component IDs are stored in the Page_visits and the Component_Visits table for the particular session user, and the Visit_Value column value increases with every page request. In the Tracking_Keys table the Keyword the value is stored as 400 for each keyword as I have set the Key as 8 and the Increment value as 50.

Is there any class or method to fetch this information [page visit/component visit value] from the Broker in DD4T?

Update 1:
In our case the tracking_key Value is not changing on the basis of page_visit/component_visit as the Increment(50) & the Key(8) values remain same.

So by using the code trackingKey.GetKey(keyCond.Keyword.Key) I am getting only 8]. To set the Key value as dynamic (using the Page_visit/component_visit value) , I need to read the Page_visit/component_visit value.

or is there any other way to handle this functionality?

Answer 1

@Manas, What I understand from your question is you are facing issue while incrementing the value of tracking key. To increment the tracking key value, you don't need to read the component visit/Page visit value. I can see some issue in your code, which seems to be a major issue in not updating the tracking key value. No need to use trackingKey.SetKey(keyword, 8);after trackingKey.IncrementKey(keyword);. So final code you can try is:

var waiPage = new WAIPage(pgModel.Id, this.HttpContext.ApplicationInstance.Context); 
//For Storing the Tracking Key
Tridion.ContentDelivery.Web.WAI.TrackingKeys trackingKey = new TrackingKeys(waiPage.User);
trackingKey.IncrementKey(keyword);
trackingKey.ExecuteUpdate();

Please share if this is not working for you..

You can get the value using the following:

var waiPage = new WAIPage(pgModel.Id, this.HttpContext.ApplicationInstance.Context); 
//For Storing the Tracking Key
Tridion.ContentDelivery.Web.WAI.TrackingKeys trackingKey = new TrackingKeys(waiPage.User);

//retrieving cond from page.componentPresentation.Conditions 
if (cond is KeywordCondition)
{
    var keyCond = (KeywordCondition)cond;
    trackingKey.GetKey(keyCond.Keyword.Key); // getting key from the condition
}

There aren't any DD4T OOTB methods to achieve this.

you should add your publication id and host (you app url) in following

<Presentation Id="1">     
  <Host Domain="localhost" Port="3035" Protocol="http" Path="/"/>
