extra 'field_' prepended to fieldnames in views $rows (Drupal 7) I created a field "myfield".  I then created a Drupal 7 view and selected the field 'field_myfield'.  (As expected the system prepended 'field_' to my fieldname.)  When I call dsm ($rows) to look at the row data that gets passed to my custom template, I see that the field is now called 'field_field_myfield'.  Why is a second 'field_' prepended to the fieldname?  Should I assume all fieldnames in $rows will have 'field_field_' prepended?
The drupal field api enters fields in the database with the field_ prefix (to avoid conflicts with other existing tables). If you use field in your name as well, it will become field_field_... in the database. 

And since views loads the fields directly from the database, the prefix is there as well.
