Query returning just one value

Rails
1

I am using INNER JOIN and it is supposed to return more than one results
but it only returns first element.
How do I get all elements in an array?
Also, in the same query I am using another INNER JOIN that is supposed
to return one value only which is does.

Thanks.

It’s hard to help you if you don’t show any code.

@dest = Destination.find_by_id(params[:id], :joins => “INNER JOIN cities
ON cities.id = city_id
INNER JOIN destination_images ON destination_images.destination_id =
destinations.id AND destination_images.is_primary_photo = 1
INNER JOIN destination_tags ON destination_tags.destination_id =
destinations.id”,
:select => ‘destinations.*, cities.name as city_name,
destination_images.url as image_url, destination_tags.tag_id as
tag_id_list’ )

pretty messy though!

tag_id_list is supposed to return an array

Yeah, any help would be appreciated :slight_smile:

First you need to explain what you do want returned and your database
structure.
