Re: [Reactor for CF] hasOne relationship question

Thu, 09 Aug 2007 15:04:36 -0700 

@Brian,

I would also prefer to use a gateway but how do I tell the createGateway
method to join the web_church_posts and xref_church_post_types table? Or
do I need to write a custom gateway query?

Pre-reactor I would just write:

SELECT xCP.Church_Post_Desc,wcp.Firstnames
FROM web_church_posts wcp, xref_church_post_types xCP
WHERE wcp.Church_Post_Type_id = xCP.Church_Post_Type_ID
ORDER BY xCP.Church_Post_Desc


@Chris,

Thanks for the order by syntax. This breaks the conditional loop
hasMore() method. Do I specify this within the loop?

Cheers,

Dave

You can call getQuery() on the iterator to return the underlying query. If you need to sort or do other things though, I would call the gateway for the other table and pass in whatever criteria (foreign key id or sorting) you need. However you can do this directly through the iterator if you really want to, using the Order object. Personally I think going that route makes things start to get ugly pretty fast. I've never quite understood why some folks want to do everything using the OO query syntax, as to me it quickly gets cumbersome and would have been easier just to call the gateway with a few simple arguments. Either way should work though.

    Hi,

    I have 2 tables in the db: web_church_posts and xref_church_post_types

    In my reactor.xml file I have setup this relationship:

    <object name="web_church_posts">
       <hasOne name="xref_church_post_types">
        <relate from="Church_Post_Type_ID" to="Church_Post_Type_id"/>
       </hasOne>
    </object>

    <object name="xref_church_post_types">
       <hasOne name="web_church_posts">
        <relate from="Church_Post_Type_id" to="Church_Post_Type_ID"/>
       </hasOne>
    </object>

    I need to output in a table the following:

    Church_Post_Desc (from xref_church_post_types)
    FirstName,Lastname etc (from web_church_posts)

    I have initially set up an iterator:

    <set name="chPostsRecord"
    value="#chRecord.getweb_church_postsIterator()#" />

    and then I am looping through this. This is producing the results in an
    unsorted order.

    My question is: Is there a better way to do this using a query instead
    of an iterator, if not how do I sort the iterator loop to display the
    Church_Post_Desc in the proper order?

    Any help, would be greatly appreciated.

    Cheers,

    Dave
