Question

I’m looking for a good way to return xml or json from a controller including multiple variables. For example:

def index
    @ad = Ad.some_annoying_ad
    @map = Map.some_map_for_something
    @articles = Articles.trending

    respond_with @articles
end

How would I best add the @ad and @map var to the @articles array? I have seen people using the merge function, but I am not sure if that’s what I’m looking for. Just want to know which way is most standard, flexible, DRY. Thanks!

Note: I am aware that respond with will automatically format the results in xml or json depending on the file extension added to the url. Thanks!

Answer 1

Instead of merging @ad, @map, just create create a new hash then put add the arrays to it, like

respond_with({:ad => @ad, :map => @map, :article => @article})

It just render all the datas with groups.
