带有自定义参数的Rails URL助手

Question

There is the following code:

before { get user_posts_path(user) }

As you can see I'm trying to make a 'GET' request, but this helper (user_posts_path) doesn't work, because I need to use user.login insteaf of user.id for this helper. How can I fix it? Thanks.

Answer 1

If user.login is just a value, you should be able to use the helper as

user_posts_path(user.login)

If you only ever need user.login in the url (instead of id), you can override the method to_param on User to return the login instead of the id. The ActiveRecord::Base version is deprecated (moved to another module), but this page lists the other versions:
