Question

So in my model a user has many roles through assignments and a role can have many users through assignments. I’ve managed to get the function for creating new assignments up and running but I want to display all the roles a user can perform on the user index page (which lists all the users).

My code for the users stub view thus far is:

  <td><%= user.email %></td>
    <td><%= user.phone %></td>
    <td><%= user.roles.select("description")%></td>

The problem here is that instead of displaying the description for the role the output is:

Any pointers would be much appreciated. Thank you in advance!

Answer 1

Map the relation into an array of the strings, so that:

<td><%= user.roles.select("description")%></td>

becomes:

<td><%= user.roles.select("description").map &:description %></td>

or:

<td><%= user.roles.select("description").map(&:description).join(", ") %></td>

to join it into a single comma-separated string.
