rails array include another array
To check if one array is included in another array in Ruby on Rails, you can use the include?
method. Here are the steps to do it:
Start by defining two arrays, let's call them
array1
andarray2
.Use the
include?
method onarray1
and passarray2
as an argument. This will return a boolean value indicating whetherarray2
is included inarray1
.If the return value of
include?
istrue
, it means thatarray2
is included inarray1
. Otherwise, if the return value isfalse
, it means thatarray2
is not included inarray1
.
Here is an example code snippet that demonstrates the above steps:
array1 = [1, 2, 3, 4, 5]
array2 = [3, 4]
if array1.include?(array2)
puts "array2 is included in array1"
else
puts "array2 is not included in array1"
end
In this example, the output will be "array2 is included in array1" since array2
[3, 4] is indeed included in array1
[1, 2, 3, 4, 5].
