QUESTION
Is it possible to alter (add more fields for each record) a returned collection in onBeforeAction or similar hook?
I have InvoiceHistory collection which I am paginating through. I also want to display as part of each invoice the company name, business address, email address and VAT registration number - and these four fields are stored in another collection. So I would like to add these four fields to each record returned from InvoiceHistory. If there is another way to do it I am open to suggestions. I am using Alethes meteor pagination which loses the helper fields returned in its itemTemplate when you navigate/browse/page to the second page. Alethes pagination also relies on iron-router, is it maybe possible to achieve what I want with the help of iron-router

@Sean. Thanks. Below is the code that uses meteor publish composite:

Answered 2017-Aug-23 at 13:44If I'm understanding you correctly, this sounds like a job for a composite publication.
Using a composite publication you can return related data from multiple collections at the same time.
So, you can find all your invoices, then using the company ID stored in the invoice objects you can return the company name and other info from the Companies collection at the same time.
I've used composite publications before for complex data structures and they worked perfectly.
Hope that helps
