Defined in:
lib/record_select/helpers/record_select_helper.rb

#record_select_observer(options = {}) ⇒ Object

Assists with the creation of an observer for the :onchange option of the record_select_field method. Currently only supports building an Ajax.Request based on the id of the selected record.

options should be a hash with all the necessary options except :id. that parameter will be provided based on the selected record.

Question: if selecting users, what’s more likely?

/users/5/categories
/categories?user_id=5
