I have a table called JOBS, and a XRef table called xExpertstoJobs, this XRef has two Joomla User type fields

On a JOBS collection view, I want to pull in the names from BOTH of these fields, however they are not rendering with the correct name and I can only pull in one

In the table view the fields are called expert_id and referrer_id

In the FIELD view at the side to drag them in they are called

Hi Jamaza,

I am not sur your Table design is correct in order to use Xref but if i anderstand what you want to do, you should have 3 Tables involved.
- JOBS: (id, title, ...)
- EXPERTS: (id, title, FK [ JUser, ... ]
- xExpertstoJobs (job_id, expert_id, ...)

So with this N:m Pivot Table :
- A Job can needs One or Many Experts Features,
- An Expert can cover One or Many Jobs.

Then, in the Jobs View Layout, you could drag :
- job_title
- - Xref [ExpertstoJobs (on Job)]
- - - Expert_title
- - - FK [Juser]
- - - - Name
- - - - UserName
- - - - etc, etc,

And, in the Experts View Layout, you could drag :
- expert_title,
- FK [Juser]
- - Name
- - UserName
- Xref [ExpertstoJobs (on expert)]
- - FK [job]
- - - job_title

Hoping that can help you ...

I had a look on your database design

Context I understood :
The 2 FK references to users are located in the EXPERTSTOJOBS table. N:1 relation
You want to list the users from the Jobs table.

Since ORM, this is incredibely simple to achieve.
This should work to grab the datas.

$this->orm(array(
	'relation' => array(

		'xexpertstojobs' => array(
			'select' => array(

				'expert_id.username',
				'expert_id.name',
				
				'referrer_id.username',
				'referrer_id.name',
			)
		)
	)
));

Then dump the loaded datas, and you will see the list of users behind the N:1 relation.

Need more explanation ?

EDIT : You need to download again because I fixed something on the ORM engine that was required for this operation.

Coding is now a piece of cake

This is what you call a component builder. I was able to master using this in a very short time and the resulting component works like a charm. Not just a basic component builder but a fully working component builder with forms fields tables all ready to go. You can make the list and item views to display in the front and back end. Also there is a great forum just starting to evolve and I'm sure this will grow very rapidly when you all realise how good this tool is.
