Question

i have this

class PagesController < ApplicationController
def index
    @textos = Texto.all
    @texto_historia         = Texto.where(:title => "História").first.contents
    @texto_capas_para_sofa  = Texto.where(:title => "Capas para Sofá").first.contents
    @texto_cortinas         = Texto.where(:title => "Cortinas").first.contents
    @texto_almofadas        = Texto.where(:title => "Almofadas").first.contents
end

The SQL output is:

  ←[1m←[36mTexto Load (2.0ms)←[0m  ←[1mSELECT "textos".* FROM "textos"←[0m
  ←[1m←[35mTexto Load (1.0ms)←[0m  SELECT "textos".* FROM "textos" WHERE ("textos"."title" = 'Hist├│ria') LIMIT 1
  ←[1m←[36mTexto Load (0.0ms)←[0m  ←[1mSELECT "textos".* FROM "textos" WHERE ("textos"."title" = 'Capas para Sof├í') LIMIT 1←[0m
  ←[1m←[35mTexto Load (1.0ms)←[0m  SELECT "textos".* FROM "textos" WHERE ("textos"."title" = 'Cortinas') LIMIT 1
  ←[1m←[36mTexto Load (1.0ms)←[0m  ←[1mSELECT "textos".* FROM "textos" WHERE ("textos"."title" = 'Almofadas') LIMIT 1←[0m
  ←[1m←[35mTexto Load (0.0ms)←[0m  SELECT "textos".* FROM "textos" WHERE ("textos"."title" = 'Informa├º├╡es de Contato') LIMIT 1

What i want is to do just one query for all “textos” model and then search inside an array or anything like that to get the specific variable.

Answer 1

You will need to get the array of all ActiveRecord objects and convert it into a hash storing the data you need.

@textos = Texto.all.inject({}) {|h, obj| h[obj.title] = obj.contents; h }

Then you will be able to access your contents with @textos["title"].
