Subject [jira] Closed: (CLK-690) Common ORM layer/package
Date Tue, 15 Jun 2010 05:58:23 GMT

     [ https://issues.apache.org/jira/browse/CLK-690?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bob Schellink closed CLK-690.
-----------------------------

    Resolution: Won't Fix

A common ORM layer might be useful for demo's but I can't see this working in real world apps.
Even the existing ORM support has a number of limitations leading to leaky abstractions and
overly complex pages. I think good examples are about as far as we should push ORM integration.

>                 Key: CLK-690
>                 URL: https://issues.apache.org/jira/browse/CLK-690
>             Project: Click
>          Issue Type: Improvement
>          Components: extras
>            Reporter: George Stan

> Please introduce a common ORM layer/package. Something like  "org.apache.click.extras.orm"
.
> Just too much of the various Click ORM code look the same, so it could be in this package.
> If there would be a "generic"(common) ORM implementation:
>  * the Click Pages would be really ORM independent, allowing to simply switch the ORM
just by changing the filter in web.xml.
>  * support for many more ORMs could come: lot of code wouldn't be duplicated. Click could
be listed in more places.
>  * a tutorial about Click+ORM would be 95% usable for any ORM with such a functionality
- no need for extra documentation.
> <pre>
> CayenneForm   \
> HibernateForm  | -> org.apache.extra.orm.EntityForm
> JPAForm             |
> BatisForm          /
>  PropertySelect    -> org.apache.extra.orm.PropertySelect
>  QuerySelect        -> org.apache.extra.orm.QuerySelect
> </pre>
