learning how to navigate dhis2 sourcecode and flow

Support - Assistance technique
1

Hi Guys

I have picked interest in the DHIS2 project, currently am trying to learn the code flow so that i can get actively involved in the development process and contribute towards the development of some modules at a later stage.

this is my understanding of the code flow using struts mvc

···

when a user logs in, execution goes to the InitAction.java action class.
but then in the action class i cant find the code that generates the objects sent to velocity pages.(main.vm&mainForm.vm)

here is the mapping in the struts xml file

/main.vm 
  <param name="page">/dhis-web-dashboard-integration/mainForm.vm</param>
  <param name="hideMenu">true</param>
  <param name="stylesheets">style/dashboard.css</param>

  <param name="javascripts">javascript/dropdown.js</param>
</action>

please could some one let me know where the code generating the objects sent to velocity is located!

thanks in advance!

Hi Morten

i have looked in the InitAction.java file and main.vm respectively, but i dont see how the “maintenanceModules” list in the code snipet below is passed to the file main.vm from InitAction.

Note: am looking at the dhis-web-dashboard-integration module

#if( $maintenanceModules.size() > 0 )

#end

···

Look at XWorkPortalModuleInterceptor (and follow the thread from there).
