Trouble with text_field_tag

Rails
1

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
here:

login_controller.rb

login.rhtml

Here is my full error output:

NoMethodError in Login#login

Showing app/views/login/login.rhtml where line #8 raised:

undefined method `tr’ for :name:Symbol
Extracted source (around line #8):

5: <% form_tag do %>

7: Name:
8: <%= text_field_tag :name, params[:name] %>

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/, 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

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.
