I am trying to make a very simple login page that has light-box like
features. The only thing I cannot get to work is the behavior of the
actual login button.
When you click on it it does nothing. I simply want to submit the info
given by the client and redirect either to a private page or make the
client log in again. Here is the code for my log in box view:
<tr>
<td>User name:
<%= text_field("userform", "user_name",:size=>"20" ) %></td><br>
<td>Password:
<%= password_field("userform", "password",:size=>"20" )
%></td><br>
<td> <%= javascript_include_tag :defaults %>
<%= submit_tag 'LOG IN', :onclick =>remote_function(:url =>
{:action => :authenticate, } ) %></td><br>
<td><input type='submit' value=' Close me! '
onClick='document.getElementById("loginpopup").style.display = "none"'>
</td>
</tr>
And here is the code from my controller for the authentication action I
am calling on:
class UserController < ApplicationController
def authenticate
@user = User.new(params[:userform])
valid_user = User.find(:first,:conditions => ["user_name = ? and
password = ? ",@user.user_name, @user.password])
if valid_user
session[:user_id]=valid_user.user_name
redirect_to :action => 'private'
else
flash[:notice] = "Invalid User/Password"
redirect_to :action=> 'login'
end
end
def login
end
def private
if !session[:user_id]
redirect_to :action=> 'login'
end
end
def logout
if session[:user_id]
reset_session
redirect_to :action=> 'login'
end
end
end
When I tried typing the code
submit_tag 'LOG IN', :onclick =>remote_function(:url =>
{:action => :authenticate, } )
into irb, I got this error message:
NoMethodError: undefined method `remote_function' for main:Object
There may be a simple error that I am making, as I am pretty new to the
ruby language. Also, if anyone knows another way to do this that will
work with the partial rendering I use to display the login box, that
would be fine, too.
