如何在控制台中测试Rails类功能？

Question

I'm trying to test some functions in a Rails Class in the rails console.

class Model
  def function1
    input_1 = ...
    input_2 = ...
    function1_hash = [ ]
    ...
    m = function2(input_1,input_2)
    function1_hash += m
  end

  def function2(input_1,input_2)
    input_1.each do |value|
      function2_hash << value
    end

    temp = input_2.anotherClassFunctionCall()
    function2_hash << temp
  end
end

So in Rails console, I'm trying to see if these functions are working properly or not but I keep running into the following error.

# Rails console
> input_1 = ...
> input_2 = ...
> Model.function2(input_1,input_2)
NoMethodError: undefined method `function2' for Model:Class

Ultimately, I need to sanity check function1 (which is definitely failing in the greater workflow), but can't seem to even recognize the functions that it depends on within the same class.

BTW, the entire rails is uploaded as a Docker file in the AWS ELB instance.And I'm using eb ssh to access rails and perform above tests.

Answer 1

Your function2 is an instance method. You need to call it on instance of Model class like:

Model.new.function2(input_1,input_2)

Happy Coding!

Answer 2

You can make your method a class method

Change:

def function2(input_1,input_2)

to:

def self.function2(input_1,input_2)
