Why is this find_all method not working rails

I have a method that is suppose to iterate over an array and match any items to a string I have in my model. My method looks like this

@new_array = @old_array.find_all { |t| t.fetch('name') == "self.object_name" }

This method should look thru the array of hashes I have and match any items that have the same name as object_name. When I test the name comparison to the object_name in console it shows true but when I run the full method described above it shows no objects found, however I know the array contains multiple objects with the EXACT same name. Any idea of whats wrong?

The array looks like so...

old_array = {"id"=>"123", "account"=>"456", "name"=>"CITY"},
    {"id"=>"456", "account"=>"567", "name"=>"CITY DIR DEP"},
    {"id"=>"456", "account"=>"567", "name"=>"BUCK"},
    {"id"=>"456", "account"=>"567", "name"=>"CITY DIR DEP"},
    {"id"=>"456", "account"=>"567", "name"=>"HAPPY"},
    {"id"=>"456", "account"=>"567", "name"=>"CIRCLE"}

and the object prints out in console as

self.object_name => "CITY DIR DEP"

You don't need quotes " at all (you literally trying to compare retrieved name with string "self.object_name" instead of the value of self.object_name):

@new_array = @old_array.find_all { |t| t.fetch('name') == self.object_name }

If you are a big fan, you can interpolate with "#{}":

@new_array = @old_array.find_all { |t| t.fetch('name') == "#{self.object_name}" }

Try this:

@new_array = @old_array.find_all { |t| t['name'] == self.object_name }
