ruby on rails - Undefined method 'errors' for nil:NilClass -
i'm following this tutorial on authentication in rails , i'm encountering issue on html signup form :
undefined method
errorsnil:nilclass
to line : <% if @user.errors.any? %>.
i searched lot on internet , tried lot of things, cannot make work.
here view :
<%= form_for(:user, :url => {:controller => 'users', :action => 'create'}) |f| %> <input class="col-lg-4 col-lg-offset-4" type="text" placeholder="email" size="6"></br> <input class="col-lg-4 col-lg-offset-4" type="password" placeholder="password" size="6"></br> <input class="col-lg-4 col-lg-offset-4" type="password" placeholder="password confirmation" size="6"></br> <%= f.submit %><div id="valid"><input class="col-lg-4 col-lg-offset-4" type="submit" value="sign up"/></div> <button type="button" class="btn btn-link col-lg-4 col-lg-offset-4"><%=link_to "already registered ?", home_path%></button> <% end %> <% if @user.errors.any? %> // error line <ul class="signup_errors"> <% message_error in @user.errors.full_messages %> <li>* <%= message_error %></li> <% end %> </ul> <% end %> my controller :
class userscontroller < applicationcontroller def new @user = user.new end def create @user = user.new(params[:user]) if @user.save flash[:notice] = "you signed successfully" flash[:color]= "valid" else flash[:notice] = "form invalid" flash[:color]= "invalid" end render "new" end end and route :
rails.application.routes.draw root :to => 'users#home' 'home' => 'users#home' 'signup' => 'users#signup' resources :users post :create end
you need rename new action signup. in current state - rails sees template signup , assumes corresponding controller action empty, nil in instance variable, because new not being called.
