rails application displaying blank space in users(venue) place - ruby

Question

I am able to post an event but when I select the user to post as, the dropdown menu shows empty spaces where the user (venue name) should be. I have tried everything that I can think of. Any ideas would be greatly appreciated.
I am on rails 4. I am using devise as well.
here are my files:
show.html.erb:
<p id="notice"><%= notice %></p>
<p>
<b>Name:</b>
<%= #gig.user.venue_name %>
</p>
<p>
<strong>Event:</strong>
<%= #gig.event %>
</p>
<p>
<strong>Date:</strong>
<%= #gig.date %>
</p>
<p>
<strong>Doors:</strong>
<%= #gig.doors %>
</p>
<p>
<strong>Showtime:</strong>
<%= #gig.showtime %>
</p>
<p>
<strong>Age:</strong>
<%= #gig.age %>
</p>
<p>
<strong>Price:</strong>
<%= #gig.price %>
</p>
<p>
<strong>Description:</strong>
<%= #gig.description %>
</p>
<%= link_to 'Edit', edit_gig_path(#gig) %> |
<%= link_to 'Back', gigs_path %>
index.html.erb:
<p id="notice"><%= notice %></p>
<div class="page-header">
<h1>All Gigs</h1>
</div>
<% #gigs.each do |gig| %>
<div class="gig">
<strong><%= gig.user.venue_name %></strong>
<p><%= gig.event %></p>
<p><%= gig.date %></p>
<p><%= gig.doors %></p>
<p><%= gig.showtime %></p>
<p><%= gig.age %></p>
<p><%= gig.price %></p>
<p><%= gig.description %></p>
<div class="meta">
<%= link_to time_ago_in_words(gig.created_at) + " ago", gig %>
<span class="admin">
| <%= link_to 'Edit', edit_gig_path(gig) %> |
<%= link_to 'Delete', gig, method: :delete, data: { confirm: 'Are you sure?' } %>
</span>
</div>
</div>
<% end %>

Answer 1

Solved it:
After running irb, I noticed that venues was null in the db. Therefore, I realized that I had to as venues in devise by creating new forms.
