You have an array of hashes and want to check if all elements are satisfying a condition.
You might want to do this in Ruby:
objects.all? { _1[:amount] > 10 }
In this case, you should remember according to with the documentation .all? might return true in this case:
[].all?
# returns true
So this thing might happen
array = []
array.all? { _1[:amount] > 1}
# will return true
array.all? { _1[:this_key_does_not_exists] > 1}
# will return true
Use
array.present? && array.all? { _1[:key_does_not_exist] > 1}
Explanation:
First check if the array is not empty and then try to apply the condition to all elements.
