This file contains the basic functions needed for this drupal module. The drupal tripal_project module maps directly to the chado general module.

Code

function tripal_project_preprocess_tripal_project_relationships(&$variables) {
  // we want to provide a new variable that contains the matched projects.
  $project = $variables['node']->project;

  // normally we would use tripal_core_expand_chado_vars to expand our
  // organism object and add in the relationships, however whan a large
  // number of relationships are present this significantly slows the
  // query, therefore we will manually perform the query
