this is the bit of code i''m having a problem with.. the odd thing..
if
i remove all the code in the def login, reload the page so the view
actually shows up put the code back in the def login and submit the
form.. it works just fine... but if i start with the code for the
login in the controller then it''s broken and starts giving me the
errors
posted below.
def login
if session[:user] = User.authenticate(params[:user][:login],
params[:user][:password])
redirect_to :controller => ''user'', :action =>
''pist''
else
redirect_to :controller => ''user'', :action =>
''mane''
end
end
because it is producing this.
NoMethodError in UserController#login
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.[]

When you submit the form however the parameters will be there and so there''s no problem. One way to deal with this would be to surround the relevant parts with if request.post? ...
