I apologize, but it must be to weariness, I do not see the error: (

the driver:

class MaximosController < ApplicationController
  before_action :set_maximo, only: [:show, :edit, :update, :destroy]

  # GET /maximos
  # GET /maximos.json
  def index
    ver_datos
    @maximos = Maximo.all
  end
....

UPDATE MODEL (same error)

the model:

class Maximo < ApplicationRecord
end

Private
  def ver_datos
    puts 'dentro de ver datos'
  end

the error:

In your Maximo model, the ver_datos method is defined as the instance method, that means you should have a maximum object and then call the method, something like:

maximo = Maximo.find(params[:id])
maximo.ver_datos

Now, if the logic of ver_datos is not related to an instance, maybe what you need is a class method, for which you should define your method as def self.ver_datos instead of def ver_datos , then then from your controller you call it with:

Maximo.ver_datos

Note that Maximo starts with a capital letter, which means that the class is called, not the instance as in the previous example.
