</div>

I am trying to implement a basic login page:

login.rhtml

1   
2 \<% form\_tag do %\>  
3 Name:  
4 \<%= text\_field\_tag :name, params[:name] %\>  
5 Password:  
6 \<%= password\_field\_tag :password, params[:password] %\>  
7 \<%= submit\_tag “Login” %\>  
8 \<% end %\>  
9

However, I’m getting the following error on line 4:

undefined method `tr’ for :name:Symbol

Am I using text\_field\_tag incorrectly? Here is my controller:

LoginController \< Application Controller

1 def login  
2 session[:user\_id] = nil  
3 if request.post?  
4 user = User.authenticate(params[:name], params[:password])  
5 if user  
6 session[:user\_id] = user.id  
7 redirect\_to(:action =\> “index”)  
8 else  
9 flash.now[:notice] = “Invalid user/password combination”  
10 end  
11 end  
12 end

No, everything looks fine. I copy / pasted your view code into a test  
view and it rendered find. Can you paste the full error output?

Thanks for your interest William. The complete versions of the pages are

Definitely odd, but based on the stack trace, the issue is with a plugin  
you have installed, krjs. I am not familiar with it, but according to  
the website:

Introducing the KRJS plugin  
[http://choonkeat.svnrepository.com/svn/rails-plugins/krjs/](http://choonkeat.svnrepository.com/svn/rails-plugins/krjs/), with less  
than 60 lines of patch to Rails’ ActionPack itself (_which probably  
means bugs are aplenty,_ would slow production sites to a crawl, and  
that its fresh from the oven too)

I would try removing this plugin or make sure you are running the latest  
version. Looks like the official site is here:  
[http://choonkeat.svnrepository.com/rails-plugins/trac.cgi/wiki](http://choonkeat.svnrepository.com/rails-plugins/trac.cgi/wiki)

Hope this helps.

Thank you very much for taking a look at this. I’ll uninstall kjrs and  
see what happens.

Thanks again,

Hi Peter

Why don;t you take a look at acts\_as\_authenticated for guidance ?

Uninstalling the kjrs plugin fixed this right up. Thanks again William.
