 This option adds the SQL directly to the Fieldmapper. This is the easiest approach to code and the reporter (and most other parts of Evergreen) will be able to make use of it, but it does have limitations. For example, it will not be available to a direct database query. Also, other fieldmapper classes cannot link to this class as they would be able to with option 2.
+Tasks:
+  * Create new fieldmapper class (this will include the SQL query)
 Example Code: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/mccanna/newdevs-sample-create-view-via-fieldmapper
-. Scroll to the bottom of the fieldmapper. You're going to insert your new class below the last closing </class> tag, and above the <!--- *****> tag.
-**NOTE:** The Fieldmapper cares about indentation. Make sure to follow the indentation examples from other classes.
+===== Option 2: Create a Database View =====
+This option creates a view on the database side which is then referenced by the fieldmapper as if it were a normal table. There are a few more steps to this than there are to option 1, but it is more flexible as well.
+Tasks:
+  * Create new database view.
+    * Decide whether this should be added to an existing schema or if a new schema should be created. (In this example, a new schema is created.)
+    * Create or modify the appropriate schema file under Open-ILS/src/sql/Pg/ (this will be used by new Evergreen installations)
+    * Create an upgrade script under Open-ILS/src/sql/Pg/upgrade/ (this will be used by Evergreen upgrades)
+  * Create new fieldmapper class (this will reference the new view as if it were a table)

+===== Making This a Core Report Source =====
-**Class id** --
+If unspecified, the new source will be listed alphabetically in the long list of "other" report sources. If you wish to bump it up to the list of "core" sources, add this to the class tag in the fieldmapper:
-**Controller** -- You have options for what this should be, and you can combine several.
+<code>reporter:core="true"</code>
-  * open-ils.cstore
-  * open-ils.reporter-store
-  * open-ils.pcrud
-**oils_object:fieldmapper** --
+For example:
+<code><class id="auj" controller="open-ils.cstore open-oils.pcrud"
+oils_obj:fieldmapper="actor::activejuv" reporter:core="true"
+reporter:label="ILS User - Active Juvenile Accounts"></code>
-**oils_persist:readonly**
