View Full Instructions

Create a new file called models/.hdinamespace under src.

Although there is no need to use namespaces in general, calculation views work best with namespaces

Use the following code in the file

{
    "name":    "db.models",
    "subfolder": "ignore"
}

Save and close the file.

If you do not see the file, go to View-> Show hidden files.
