问题 I was wondering if it is possible to have multiple models all using one central model for its images using paperclip.. So for example I would have a photo model which would use paperclip to store its urls etc In my case I have 2 models, portfolio and post, both of which have a form which allow you to upload images and other attributes to the model. So can both models have a has_many :photos, :dependent => :destroy accepts_nested_attributes_for :photos or would i need to create separate models

问题 We have to create a request system which will have roughly 10 different types of requests. All of these requests will belong to the 'accounting' aspect of our application. Therefore we've called them "Accounting requests". All requests share maybe only a few columns and each has up to 20 columns individually. We started to wonder if having separate tables for each request type would be practical in terms of speed when we start to have to do very complicated joins or queries, for example,

问题 I'm a Rails 3 beginner, but have experiences with other MVC web frameworks and need a starting hint about how to setup my routing in Rails. The application should allow users to register and after that the users data should be available at URLs like: http://domainname/username/xyz The common and user independent part should be available at http://domainname/abc To distinguis between both routes, I would force usernames to have at least 6 characters and all "abc"-routes will have 5 or less.

问题 I'm grateful to the folks who helped me meander my way through a diagnostic process here. I rewrote the code that i am hoping will continue to work through future versions of jQuery. I am concerned, though, about two things: Have i coded something else that is going to come back and bite me in the tail? Quite a few clients complete part of the questions, close the browser and expect their work to be there when they came back to finish. So the entire form is submitted every time a radio button

问题 I have a rails app that was built using foundation 3 (not using the gem. It is located in vendor/assets/stylesheets/foundation.min.css). And I want to gradually convert my styling code to Bourbon/Neat. One thing I have to have in mind is not to break the previous layouts while I'm not done with the recoding. Is it possible to do this? rails version: 3.2.13 ruby: 1.9.3 回答1: For any given page in your app, you can include whatever styling you want by including the stylesheets on that page. So
