Question

I am using Ruby on Rails 3 and I would like to implement something that works like params.

Normally in a RoR application you can use params[:name] to access the ‘name’ value. In my case I need to have “something” like my_function_params[:name] that works like params[:name].

I don’t need all features of the params method because I will use that like a variable statement and only internally my methods. This is because I would like to work on that instead of local variables.

Example:

# What I would like to do

my_function_params[:name] = "Test name"
if my_function_params[:name] == "Test name"
  ...
end

instead of

# What I would not do

name = "Test name" == "Test name"
if name
  ...
end

How can I do that?

You can use a Hash:

my_function_params = {name: "Test name"}
my_function_params[:attribute] = "Another attribute"

if my_function_params[:name] == "Test name"
  puts "hi"
end

=> hi
