Question

I have some basic search implemented and I am trying to match multiple attribute to the 1 set of keywords.

I have this:

listings = Listing.order(:headline)
listings = listings.where("headline like ?", "%#{keywords}%") if keywords.present?

I have multiple attributes for listings that I would like to check to see if the keywords appear in – e.g. say listing.neighborhood.name or listing.type.name.

How do I write all of that in 1 statement? I tried:

listings = listings.where("headline like ? or neighborhood.name like ?", "%#{keywords}%")

But that returned this error:

ActiveRecord::PreparedStatementInvalid: wrong number of bind variables (1 for 2) in: headline like ? or neighborhood.name like ?

One obvious solution is just to add "%#{keywords}%" again…but that hardly seems DRY.

How do I add check both the neighborhood.name and type.name and others in that 1 query? Or should I be approaching this another way?

Thanks.

Edit 1:

When I try the non-DRY way of simply adding another {keywords} parameter, this is the error I get:

ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: neighborhood.name: SELECT "listings".* FROM "listings"  WHERE (headline like '%sterling place%') AND (headline like '%sterling place%' or neighborhood.name like '%sterling place%') ORDER BY headline.

Which I think is because neighborhood is a foreign_key on my listings model, and not an attribute in and of itself. There is a simple association between the listings & neighborhood model.

Answer 1

Try this (still a non-DRY way) :

key = "%#{keywords}%"
listings = Listing.includes(:neighborhood).where("headline like ? or neighborhoods.name like ?", key, key)
