    <p>I have created a BETA Invitation system by following this tutorial. <a href="http://railscasts.com/episodes/124-beta-invitations" rel="nofollow">http://railscasts.com/episodes/124-beta-invitations</a>. Users can also follow one another in my Rails app.</p> <p><strong>Currently, I have two methods:</strong></p> <ol> <li><p>Allows the User to follow all ADMIN USERS on Sign up.</p></li> <li><p>Allows the User to follow INVITER on sign up.</p></li> </ol> <p><strong>The problem I am having is:</strong> </p> <pre><code>no such column: TRUE: SELECT DISTINCT "users".* FROM "users" INNER JOIN "invitations" ON "invitations"."id" = "users"."invitation_id" WHERE (invitations.recipient_email = 'spedroza@usc.edu' OR users.admin IS TRUE) </code></pre> <p>Is there anyway to fix the second method so it wont follow the inviter if he is an ADMIN USER?</p> <p><strong>MODEL</strong></p> <p>USER</p> <pre><code>class User &lt; ActiveRecord::Base attr_accessible :name, :email, :password, :password_confirmation, :invitation_token has_many :relationships, foreign_key: "follower_id", dependent: :destroy has_many :followed_users, through: :relationships, source: :followed has_many :reverse_relationships, foreign_key: "followed_id", class_name: "Relationship", dependent: :destroy has_many :followers, through: :reverse_relationships, source: :follower has_many :sent_invitations, :class_name =&gt; 'Invitations', :foreign_key =&gt; 'sender_id' belongs_to :invitation after_create follow_inviter_and_admins #--------HERE!! def follow_inviter_and_admins #--------HERE!! return true if admin? users = User.joins(:invitation).where('invitations.recipient_email = ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
