Hi,

I have a form for creating users …

\<% form\_tag ‘userconfirm’ do -%\>

Username  
\<%= text\_field 'user', 'login' %\>

Password  
\<%= password\_field 'user', 'password' %\>

Confirm Password  
\<%= password\_field 'user', 'password\_confirmation' %\>

\<% end -%\>

My question is, on the controller end, how do I access the parameter  
for login and password? I thought it would be params[:login] and  
params[:password], but that is not right. Any help is appreciated, -  
Dave

My code now:

```
    def userconfirm
            @user = User.new(params[:user])
            if @user.save
                    # Create session
                    if (log_user_in(params[:login],

```

params[:password], nil))  
redirect\_to :controller =\>  
‘order’, :action =\> ‘new’  
else  
flash[:notice] = “You are not logged  
in.”  
redirect\_to :action =\> “start”  
end  
else  
render :action =\> ‘userinfo’  
end  
end

Just take a look in your log files and you’ll see that they arrive as  
params[:user][:login], params[:user][:password]

Add the following if you are unsure in the controller method of  
interest:

puts params.inspect

it will dump the values to the console as another option to check…

Thanks for your help. It was indeed params[:user][:login]. I didn’t  
know I could use the log file so I’m grateful also for that info, -

If you are using rails 2, you can also use the debugger which is a TON  
of  
help. start script/server with --debugger and put “debugger” on the  
line  
you want it to stop on. Then you can inspect variables, step, and even  
evaluate routines. WAY cool!!
