Textbox to session

Rails
1

Can anyone help me out with storing a user’s location to session to be
used several times by a user during a login ? I need to create a
textbox where the user enters there zip code and then I need to hold
that zip code value in session to be used for several queries
throughout the user’s time within the site. I also would like to
return the user’s actual town and state after the zip is submitted but
that is of lesser importance. I think I almost have the controller
code but not quite there yet

def store_location
session [:location] = params[:location]
end

I think its close although I am new and not totally sure what it is
doing. The view code I don’t even know how to start though and I
assume it is only the controller and the ‘store location’ view that I
need to code for?

Thanks

The code you have there will do what you expect – it will store
exactly what is on the form submitted to that controller into the
session.

right now, horrible at html,css…

I’ll paste a simple controller and an associated view (which includes
a form). That might help.

Here is my login form, in app/views/session/new.rhtml

<% form_tag(:controller => "session", :action => "create") do -%>
Login
<%= text_field_tag 'login' %>
Password
<%= password_field_tag 'password' %>
<%= submit_tag 'Log in' %>
<% end -%>

And here is the part of my controller which handles it:

class SessionController < ApplicationController
def new
end

def create
if using_open_id?
open_id_authentication(params[:openid_url])
else
password_authentication(params[:login], params[:password])
end
end

def destroy
# self.current_user.forget_me if logged_in?
cookies.delete :auth_token
reset_session
flash[:notice] = “You have been logged out.”
redirect_back_or_default ‘/’
end

def password_authentication(login, password)
self.current_user = User.authenticate(login, password)
if logged_in?
successful_login
else
failed_login
end
end

def failed_login(message = “Authentication failed.”)
flash.now[:error] = message
render :action => ‘new’
end

def successful_login
redirect_back_or_default(’/’)
flash[:notice] = “Logged in successfully.”
end
end

“Your location is #{params[:location]}” would work.

Note that it is subject to XSS attacks if it is displayed to 3rd
parties. You’d need to escape the HTML in it if it was.

OK I think I have the view working, textbox is there
here is my method in the controller:

def store_location
session[:location] = params[:location]
redirect_to :action => ‘list’
flash[:notice] = "your location is "
end

so right now you enter a zipcode and it should be storing it to the
session, the redirect keeps me on the same page and the flash notice
seems to work as well. What I would like to do now is add to that
flash notice the actual value I just stored in the hash…something
like …flash[:notice] = "your location is " + [session value]

can anyone help with the syntax on this?

BTW does that session code look correct for actualy getting the zip
stored in the session? I have not been able to verify yet becasue I
cant get the flash to return it.

here is my view code just in case you need it…

<%= start_form_tag :action => ‘store_location’%>
<%= text_field ‘location’, nil %>
<%= submit_tag ‘your location’ %>
<%= end_form_tag %>

look ok?
