How do I configure an ultisnip to override an existing snippet?

Question

I use rails.vim but would like to override one or two snippets with my own using ultisnips.

I've created the snippets but since they're already defined by rails.vim a menu now appears when triggered. I'd like my snippets to override the existing one to avoid the menu.

The solution is to use priority directive. All snippets default to a priority of 0. Therefore, adding this to the top of my custom snippets solved the issue:

# top of custom snippets file
priority 1
