Not part of this problem but it should be flash not falsh

else
falsh[:notice] = ‘Problem update.’

Same again

end

Can you post the section of db/schema.rb that shows the users table.
Also post user.rb (cut out any methods that are not relevant here, if
there are any)

I think the issue is here

def update

@user = User.find(params[:user])
^
if you make it

def update
  @user = User.find(params[:id])
                                          ^

Does that fix it?

Basically I think the way you have it now has two issues
A) is trying to find the user based on the new attributes before
they’ve been updated in the db
B) more importantly, treating the user’s attributes like options sent
to the ‘find’ method.
I think you can do this but you would have to specify User.find(:all,
params[:user]) or User.all(params[:user])

Hope that helps,
