Solution 1

You can use the with_role method with a User class to find all users who has a role in version 3.1.0.

User.with_role :admin

Solution 2

I'd ask the role for it's users

admins = Role.find_by_name('admin').users

the with_role method is for a particular user instance, not at the class-level for all users. If you want to implement that you'd have to do something like this:

#not 100% on this code, haven't tested it, but you get the idea.
User < ActiveRecord::Base
  def self.with_role(role)
     my_role = Role.find_by_name(role)
     where(:role => my_role)
  end
end

Solution 3

Have you mentioned resourcify in the models in order to put roles on

class User < ActiveRecord::Base
  resourcify
end

With this you can use with_role and find_roles class methods.

How can i get all users with specific role when using rolify? I've tried the following but it didn't help:
```
User.with_role :admin
```
I get the following error:
```
NoMethodError: undefined method `with_role' for #<Class:0x0000000743f9c0>
```
Couldn't find any way to do this.

Trying to do it like this gives the following: User Load (0.3ms) SELECT users.* FROM users` INNER JOIN "roles" ON "roles"."resource_type" = 'User' WHERE (roles.name = 'user' AND roles.resource_type = 'User') => #<ActiveRecord::Relation:0x36e47c4>`

This was an issue which has been fixed, just check this github.com/EppO/rolify/commit/…

Using resourcify in user model breaks succh methods as all, first etc. When i call User.all i get NoMethodError: undefined method find_or_create_by' for #<Rolify::Adapter::ResourceAdapter:0x00000005ed3870>`
