Class Method Details

.has_portal(name, options = {}) ⇒ Object

Based on +has_many+, but creates a special Portal association instead.

Custom options:

  • :portal_key - The key used for the portal in the FM Data JSON portalData.
  • :attribute_prefix - The prefix used for portal attributes in the FM Data JSON.

Example:

has_portal :jobs, portal_key: "JobsTable", attribute_prefix: "Job"

Instance Method Details

#association(name) ⇒ Object
