Update User Info with restful_authentication plugin in Rails?

I want to give the users the ability to change their account info with restful_authentication plugin in rails.

I added this two methods to my users controller:

  def edit
    @user = User.find(params[:id])
  end

  def update
      @user开发者_Go百科 = User.find(params[:id])

      # Only update password when necessary
      params[:user].delete(:password) if params[:user][:password].blank?

      respond_to do |format|
        if @user.update_attributes(params[:user])
          flash[:notice] = 'User was successfully updated.'
          format.html { redirect_to(@user) }
          format.xml  { head :ok }
        else
          format.html { render :action => "edit" }
          format.xml  { render :xml => @user.errors, :status => :unprocessable_entity }
        end
      end
    end

Also, I copied new.html.erb to edit.html.erb. Considering that resources are already defined in routes.rb I was expecting it to work easily, but somehow when I click the save button it calls the create method, instead of update, using a POST HTTP request. Immediately after that it automatically logs out from the session.

Any ideas?

Could it be possible that the selected user could not be found in your edit method? Then @user is empty and your form thinks that you are creating a new user.

Try to add debugging output in the edit method, like this:

def edit
  @user = User.find(params[:id])
  logger.debug "Found user = #{@user.inspect}"
end

And check if your log messages shows that the user is found or not.
