问题 I have a legacy database that I'm working on getting ActiveRecord to work with. I've run into a problem with join tables. I have the following: class TvShow < ActiveRecord::Base set_table_name "tvshow" set_primary_key "idShow" end class Episode < ActiveRecord::Base set_table_name "episode" set_primary_key "idEpisode" end And then I have a table called tvshowlinkepisode that has 2 fields: idShow, idEpisode So I have 2 tables and a join between them (so a many to many relationship), however the

问题 After working on several large web applications, and seeing gigantic style sheets with no clear structure, I'd really love to know if people have found ways to keep their css clean for large and complicated web apps. How do you move from a legacy, mess of css to cleaned up, nicely cascading, DRY stylesheets? The app I'm currently working on has 12000 lines of css. It's grown to this size organically as early on there were no standards or review of the css, the only rule was to make the app

问题 Its being a few months since I am working with java legacy code, this are some of the things I am dealing with: 0% test coverage. Huge functions in occasions I even saw some with more than 300 lines of code. Lots of private methods and in occasions static methods. Highly tight coupled code. At the beginning I was very confused, I found difficult to use TDD in the legacy. After doing katas for weeks and practicing my unit testing and mocking skills, my fear has decreased and I feel a bit more

问题 For legacy reasons, I'm using CVS on a project. Recently I committed some changes which broke our code and I needed to revert them. What's CVS's analog of git revert -r <old_revision> ? Looking at past questions like How to revert big change, CVS commits don't group the files that were changed. Is the only way to revert by using dates? Also, what's the best way to view past changes? CVS log outputs too much info, most of which is unnecessary. I want to see commit messages and changed files.

问题 I am adding MVC to a project that has MANY legacy webform pages. This works fine. However, I currently have a separate masterpage for MVC and for the webforms. The two master pages produce essentially identical output. I'd really like to kill the webforms one and just use the MVC master page with all my pages and stay DRY. Not being DRY has already bitten me a couple times when I forgot to change both. I tried doing the obvious way and just pointing the webform content page's MasterPage

问题 I have a legacy application written in .Net. No sources available. It uses vb scripting to extend it inner logic via events handling. So it's a mix of com and .net. I used SpyUI app and observed that UI is written with Windows Forms. Controls are titled in .Net style & it looks like windows forms one (vc++ and vb UI looks completely different). I want to extend application UI by achieving System.Windows.Forms.Form instance for the main form and modify controls tree. So i write code in vb
