Question

I have some Ruby code that is putting out JSON like this:

def nearby
  #@bathrooms = Bathroom.geo_scope(:origin =>[params[:lat],[params[:lon]]], :within => 5)
  lat = params[:lat]
  lon = params[:lon]
  #@bathrooms = Bathroom.geo_scope(:within => 5, :origin => [45.580639,-122.677682], :order=>'distance')
  @bathrooms = Bathroom.geo_scope(:within => 3, :origin => [lat,lon], :order=>'distance')
  respond_to do |format|
    format.json  { render :json => @bathrooms }
    format.js   { render :nothing => true } 
  end   
end

The result is something like this:

 [{"ID":129,"access":"1","avail":"0","bathroomtype":"0","city":"PORTLAND","comment":"","country":"US","created":"0000-00-00 00:00:00","directions":"The two bathrooms are in the long hallway at the back of the restaurant, past the bar.","distance":"2.94986114636676","lat":"45.539217","lon":"-122.661795","modifed":"0000-00-00","name":"Echo","postal":"97212-3727","slug":"echo-portland170","source":"","state":"OR","street":"2225 NE Martin Luther King Jr. Blvd"},

What I don’t know how to do is to name the set? For example, after the first enclosing bracket I would like to name the set bathrooms. How can I do this is Rails?

Answer 1

It looks like @bathrooms is a list, so you can’t assign keys to elements in lists. You’ll need to make a map first. For example, if you only want the first element:

format.json { render :json => {:bathrooms => @bathrooms[0]} }

To set all list elements:

format.json { render :json => {:bathrooms => @bathrooms} }
