loginGenerator - getting logged in username

Rails
1

i am working on a site taht uses loginGenerator…

it’s a great little package, but i am running into one little problem…

i would like to have something that says:

"logged in as " in the site, but i am not quite getting it…

what i am using is:

You are logged in as: <%= @session[:user] %>

but i have tried:

You are logged in as: <%= session[:user] %>

anyone have any ideas?

also…

is there a way to get a list of all the current session variables?

in php, it would be something like:

print_r($_SESSION);

but i dunno how to do it in rails.

thanks!

try session[:user].login, or whatever your username column is called.
session[:user] contains the user object.

p session or puts session.inspect if you want it dumped to the
console, <%= session.inspect %> if you want it in a webpage.

Can you post the schema of your user table?

Can you post the schema of your user table?

martin

yes:

CREATE TABLE users (
id int(11) NOT NULL auto_increment,
login varchar(80) default NULL,
password varchar(40) default NULL,
PRIMARY KEY (id)
) ENGINE=MyISAM DEFAULT CHARSET=utf8

i might also note that i tried:

You are logged in as: <%= @session[:login] %>

too…

thanks!

<%= @session[:user].login %> should work fine

i don’t know why, but i also installed the LoginGenerator (and the ACL
system) and for some unexplanitory reason, @session[‘user’] (as apposed
to @session[:user]) worked for me.
don’t know why, but i hope it helps.
either way, the best way at it seems to do @session.inspect and see what
name the username/login variable is listed under.

good luck,

<%= @session[:user].login %> should work fine, then, assuming that
session[:user] itself is getting set correctly.

@session[‘user’] is not the same as @session[:user] - it just happens
that for many (but NOT all) of the Hash-like objects that Rails
creates, they have been tweaked to not care if you’ve given a symbol
or a string as the key (HashWithIndifferentAccess is the class of
these critters).

Try this to prove it to yourself:

h = {} # new Hash
h[‘a’] = ‘hello’
h[:a] = ‘asta la vista, baby’
puts h.inspect

For whatever reason, session is a regular Hash and not at
HashWithIndifferentAccess, so you need to know the exact keys
(including whether or not it was a String - ‘user’ - or a Symbol -
:user). This might help in your views:

<%= debug session %>

<%= debug session %>

there is still something stumping me here…

i tried this, and got the stuff at the bottom of this post… which looks
ok…

@session.inspect gives me the second set of output (on bottom of
post)…

but @session[:login] still gives me nothing…

thanks for the help so far.
