Comment 4 for bug 1847800

There's already an implicit relationship between primary and secondary admin pages in the IDL, i.e., the primary class should have a link to the secondary. Would it make sense to add a "config_field" attribute to IDL links to make the relationship explicit? Then the admin page component could check for the attribute when loading the IDL class definition; if config_field = true, it could add a link to the grid directing the user to the appropriately-filtered secondary admin page.

For example, the IDL class definition for config.z3950_source has a link to config.z3950_attr. We would add a "config_field" attribute to the link field, like so:

<field reporter:label="Attrs" name="attrs" oils_persist:virtual="true" reporter:datatype="link" config_field:"true"/>

Since we have a config_field attribute, the Z39.50 Sources grid would use the other IDL attributes
to construct a link to this URL:
/eg2/en-US/staff/admin/server/config/z3950_attr?gridFilters={"source":"oclc"}

Working branch user/jeffdavis/lp1847800-secondary-admin-pages doesn't construct that link yet, but it attempts to make the config_field IDL attribute available to Angular in order to do so:
