user.roles -- How do you list the role names of the user?

[Bob Sanders]

Hello,

I want to list out the role names that belong to a user. I have
user.roles as the table, so I'm interested in the "name" column on that
roles table. If I want to separate the names using a comma [ e.g. using
join(", ") ], how would I do it?

For instance:

<% for role in user.roles %><% role.name %><% end %>

displays all of the roles of the user, but without the comma. There must
be a better way to do it (a less tedious way), and also separate them
with commas?

Any idea?

What happens when you do user.roles.join( ',' ) ?

You may need to explain more about the object model. Is this part of an
ORM library? Og? Sequel? ActiveRecord?

It'll be a Rails question. Please take Rails questions to the Rails list.

The OP wants <%= user.roles.map(&:name)*',' %>

Voila

<%= user.roles.join(",&nbsp;") %>

Hi Jake, I tried that -- and ended up with a pound sign (#)

I'm guessing that brings up an array, and I'll have to incorporate the
"name" in there somehow

e.g. user.roles[name].join(",&nbsp;")

(which is probably totally wrong)

any ideas guys?

Clifford! Thank you, man!

I didn't see your solution before. You got it. Thank you, thank you,
