Ruby on Rails: how can I make a form/controller for a model which holds a key/value pair?

Question

I have a model called configurations which holds key value pairs in my database to store options for the website. The schema looks like this:

create_table "configuration", force: :cascade do |t|
  t.string "key",   limit: 255
  t.string "value", limit: 255
end

I would like to create a page in the website, so as an admin, I can edit the values on the configurations without the need to enter the database and change them manually.

However some of the values are strings, some are integers and some are Boolean, and I would like that to be reflected in the page, so a particular key might have a drop down of true/false for a Boolean value or a text box for a string etc.

Would this be possible, and if so, how do I write a controller/form to implement this please?

Have you tried something? There is a lot of tutorial and guides in the internet, what have you tried so far? — Roman Kiselenko, Mar 28 '17 at 08:43

You can do above by standard Scaffold

rails g scaffold Configuration key:string value:string

then execute rake db:migrate

& allow this page only for admin

Scaffold will generate rails standard model, view & controller for the same.
