help on session in Ruby

hi all,
i have one issue after entering username and password on login popup and clicking login button the user is logged in but i have to refresh the url
i have check the log but nothing is there,i have set the session key and secret in ‘session_store.rb’, i am running my local app on ip on 3006 port

Without showing us the relevant code we have no hope of helping. We
have no idea of how you are handling login or what code is executed
when the login button is clicked.


i am using ruby 1.8.7 and rails version 2.3.11 with ruby gem 1.6.2 i am setting the key and secret value in session_store.rb with following code

ActionController::Base.session = {

:key => ‘_myapp’,
:secret => ‘071a1167c4870bfff95a61835288f9fa9eb158298e1c5623e8d7223fa7a68c9d485b4e27a8e705c2485631bfc28f48b895c486536c8f53856ce3480f0d9ea8b’
#:domain => :all


def validate_user

    login_details = params[:login_details]
    user_name = login_details['username']
        user_password = login_details['password']

I think you had better have a look at the Rails Guide on Debugging.
That will show you how to use ruby-debug to break into your code to
inspect data and follow the flow. Then you should be able to work out
what is going wrong.

I would also say that code looks incredibly complex and should be
refactored to make it simpler. Personally I would not even attempt to
debug code as complex as this, but would refactor it into simpler
chunks first, there is a good chance it will then work. Sending email
and rendering inside a method called validate_user, for example, is
ridiculous (IMHO).


hi colin,
i debug the code(method) but method giving the right values.My problem is that as i said when user logs in
it is done in that method but i have to refresh the url to take the user on to new page if it valid user.

I don't fully understand what you mean and as I said I have not looked
in detail at the code, you say that it is following the correct flow,
at the end does it instruct it to render or redirect to an appropriate
page? If so does the log say that it is doing that correctly?
