The explanation from api.rubyonrails.org is rather baffling for a newbie like me,
collection_select(object, method, collection, value_method, text_method, options = {}, html_options = {})
Still managed to get the dropdown menu working for my application after searching through the web. There are already quite a few useful resources available in the net for helper method collection_select.
But I seem to lost in the code again looking back at it after a while. And am too lazy to look through all the stuff again. So I try to make a diagram to put down what I already understand from those resources. Might not be the best or complete explanation, but just try to help myself to be able to view it and quickly get a grasp of it.

Have to say this is not the most comprehensive collection_select post out there BUT it is straight to the point and illustrates the theory perfectly. Good job

You just saved my life. The ‘method” thing was killing me. Read this and it works.
Thank you. Ben
