Question

I have an array:

array1 = [1,2,3,4,5,:value => 'value']

I want to create second array, who is the copy of first array minus :value element (addition: i don’t know position of element exactly)

#expected result
array1 = [1,2,3,4,5,:value => 'value']
array2 = [1,2,3,4,5]

#my failure attempt
array2 = array1.delete(:value) # => nil

How can i do this?

Answer 1

You can try this

array2 = array1.reject{|a| a.is_a?(Hash) && a[:value]}

as @mu is too short said this will be safer:

array2 = array1.reject{|a| a.is_a?(Hash) && a.has_key?(:value)}

Or

array2 = array1 - {:value => "value"}
