Raspberry Pi validate function

_default/raspberry_def

This validate function is used only in the rapsberries subsystem. As consistent with all validation functions, it is run as well as the [default validation function]Default nEDM validate function. The purpose of this validation function is to allow users to only submit code/documents corresponding to a particular Raspberry Pi. See here for more information on how Raspberry Pis are used in the nEDM systems.

Security

This validation function simply checks to see if the user is a limited user, meaning the user has the role: "raspberry_lmtd". (The user must also have "raspberries_writer" to save in the database, but this is handled by the default validation function.)

In the raspberry database, documents have types corresponding to the mac id of the device, e.g.

{
  "type" : 202481600141232,
  // ..
}

or

{
  "type" : "202481600141232_cmd",
  // ..
}

If a user has the "raspberry_lmtd" role, then it is also required that this MAC ID is present in the user roles. In other words, in this case, the user would need to have the user role "202481600141232" to be able to edit/post/delete the documents.
