I need to store data from a database search in an array, but with the code below it only stores a value in the array.
@busca= Item.find(:all,:conditions=>{:codigo=>params[:codigo]})
@busca.each do|buscador|
@novamatriz=Array.new
@novamatriz.append(buscador.modelo)
end
A slightly more elegant solution. If modelo is a simple value (string, int):
@lista = Item.where(codigo: params[:codigo]).pluck(:modelo)
If it's an association:
@lista = Item.where(codigo: params[:codigo]).map(&:modelo)
In the latter case, if you are associating with a collection and generating the n + 1 problem, you can use includes :
@lista = Item.includes(:modelos).where(codigo: params[:codigo]).map(&:modelo)
I was able to identify the error, I was creating a new array all the time. I solved only by taking the creation of the array of each structure.
@busca= Item.find(:all,:conditions=>{:codigo=>params[:codigo]})
@novamatriz=Array.new
@busca.each do|buscador|
@novamatriz.append(buscador.modelo)
end
