I often find myself writing this:
params.delete(:controller)
params.delete(:action)
params.delete(:other_key)
redirect_to my_path(params)
The trail of deletes doesn't feel right and neither does:
[:controller, :action, :other_key].each do |k|
params.delete(k)
end
Is there anything simpler and cleaner?
Starting from Ruby 3.0, Hash#except is supported directly. This means we would not need activesupport to access Hash#except.
From documentation:
Hash#except(*keys) → hash
This method returns a new hash, which includes everything from the original hash except the given keys.
example:
h = { a: 100, b: 200, c: 300, d: 400 }
h.except(:a, :d) #=> {:b=>200, :c=>300}
