问题 At work I have several pages, each with buttons in the same places, and with the same properties. Each page also has minor differences. To that end, we created a userControl Template and put all the buttons in it, then applied that user control to all the pages. However, now it's rather hard to access the buttons and modify them from each page's xaml, because they are inside a UserControl on the page..... How do I elegantly access the buttons from each page? What I've tried: Currently, we

问题 I have a rails4 app with rspec + factory_girl. I would like to test the validation that makes sure the product has at least one feature, competition, usecase and industry. The first 3 must belong to a product, but industry can exist on its own. I haven't tried to put industry in the test yet since I can't even make work the first 3. I tried the approach below in which I create a product factory that has product_feature, product_competition and product_usecase. For some reason it's not working

问题 I'm trying to make a nested form with form_for and fields_for . After much research and in-success, not working on my project anymore. I'm just trying to recreate a railscast to see what have I done wrong. I'm trying to re-create the example found at http://railscasts.com/episodes/196-nested-model-form-part-1 which shouldn't be that hard since the code is there, but I can't manage to create questions from the survey. Here is my code until now: rails new surveysays rails g scaffold survey name
