Passing value params from one method to another method rails

I have a method: index that gets the value of the checkbox per post

def index
  session[:post] = params[:checkbox_array]
end

The value of params[:checkbox_array] is:

{"2m"=>"1", "2"=>"2", "3m"=>"3", "3"=>"4", "4"=>"5", "4a_5d"=>"6", "5"=>"7", "6m"=>"8", "6"=>"9", "7m"=>"10", "7"=>"11"}

When I click on button to make the post I am redirect to page interval_identification.html

I want to get the variable value @post on method interval_identification on controller.

I can not call the index method inside the interval_identification method because I'm going to do a get in the interval_identification and the value of the @post variable should be the same when the post was done in the index.

I was researching and saw that the solution would be to save the @post value of the method index in the session, and then reading that value and assigning it to a variable in the interval_identification method, but I do not know how to do that, can you help me?

def interval_identification
  @post = session[:post]
end

I tried to do it. but when I show the @post value on interval_identification view, the value is blank

interval_identification.html.erb:

<a><%= @post %></a>

Accessing the session is pretty straight forward:

def index
  session[:post] = params[:checkbox_array]
end

def interval_identification
  #session[:post] should be here waiting for you!
end
