The Plan model has an objects field, which is stored in the database in json format.

  def new @plan = Plan.new @restaurant = Restaurant.find(params[:restaurant_id]) @plans = @restaurant.plans respond_to do |format| format.html format.json { render json: @plans.distinct.pluck(:objects) } end end def plan_params params.require(:plan).permit(:restaurant_id, objects: [ :width, :height, :fill, :radius, :blendMode, :rotate, :strokeWidth, :stroke, :type, :x, :y]) end

When I deduce object that turns out an array in an array:

 {"objects":[[{"width":308,"height":248,"fill":"#fff","radius":0,"blendMode":"normal","rotate":0,"strokeWidth":1,"stroke":"#b9b9b9","type":"rectangle","x":84,"y":46},{"width":260,"height":150,"fill":"white","blendMode":"normal","rotate":0,"strokeWidth":1,"stroke":"#b9b9b9","type":"circle","x":497,"y":104},{"width":69,"height":51,"fill":"#fff","radius":0,"blendMode":"normal","rotate":0,"strokeWidth":1,"stroke":"#b9b9b9","type":"rectangle","x":149,"y":112}]]}

How can I output to be only 1 array?

 {"objects":[{...}]}
  • And what type of result is this @plans.distinct.pluck(:objects) ? - Mikhail Vaysman
  • What kind of JSON do you have in the database? Is it an array of an hour? - D-side
  • @MikhailVaysman is obtained [[{...}]] - Silentium
  • @ D-side Well, yes, the array - Silentium
  • @ D-side can do something like @plans.distinct.pluck(:objects) different way, not an array, but something like @plans.objects , when I do something like that in the console, it displays what it needs - Silentium
