Exception: can't dup Symbol

Rails
1

Hey everybody,

I’m trying to test a little piece of code I wrote, and I get the
following error:

Exception: can’t dup Symbol

It happens in the following line: try_to_login @valid_user, :remember_me
=> “1”,
where the function try_to_login is:

def try_to_login(user, options = {})
user_hash = {:screen_name => user.screen_name, :password =>
user.password}
user_hash.merge!(options)
post :login, :user => :user_hash
assert logged_in?
end

I can’t isolate the error, can anybody throw some light on it?

Thanks a lot in advance!

Hi,

It looks like maybe issue with passing the remember_me as part of
params[:user] … can you post your controller’s action handling this
request ?

You meant to write :user => user_hash
