 Besides simplified construction of queries and views, it also facilitates keyless (=implicit) constraints e.g. in CRUD forms and XML imports:

 For simple components, it is sufficient to specify the foreign key as join:
 
-{{{
-s3db.add_component("org_office", org_organisation="organisation_id")
+{{{#!python
+s3db.add_components("org_organisation", org_office="organisation_id")
 }}}
 
 This assumes that the component alias is the same as the name of the component table without prefix, e.g. {{{tablename = "org_office" => component alias = "office"}}}. If you want set the alias explicitly, you can instead describe the join in a dict:
 
-{{{
-s3db.add_component("org_office", org_organisation={
-                                        "name": "headquarter",          # the component alias
-                                        "joinby": "organisation_id"     # the foreign key
-                                 })
+{{{#!python
+s3db.add_components("org_organisation", 
+                    org_office={"name": "headquarter",       # the component alias

+                               })

 Component joins can be filtered, so that only a subset of the records in the component table forms the actual component:
 
-{{{
-s3db.add_component("org_office", org_organisation={
-                                        "name": "headquarter",          # the component alias

-                                        "filterfor": 4,                 # the value(s) to filter for

 This requirement is often called "singe-record component" or "subtable", and can be defined in the join dict:
