ActiveRecord serialize method not returning YAML array in test environment.

[Marcin Seroczyński]

Hello,

I've got a problem with deserialization of AR "serialize" method
(http://apidock.com/rails/ActiveRecord/Base/serialize/class) in my
tests.
It just gives me pure String instead of my data Array.

Example:
User > AR::Base
serialize :roles, Array
end

Console:
u = User.new
u.roles = ["admin", "support"]
u.save
# => true

User.first.roles
# => ["admin", "support"]


In test environment:
User.first.roles
# => "--- \n- admin\n"

it is a String. It seems that YAML serialize is not working there but
I have no idea what to do to get it working.

I was already trying to figure it out with these, but with no luck.

Any advice would be greatly appreciated.

After all to bypass this I needed to call the data in database
directly without involvement of "serialize" AR method.

YAML::load(User.first.roles_before_type_cast)

And now test environment also directly parses the data and give me
correct roles Array.
