I have just installed paperclip into my ruby on rails blog application. Everything is working great...too great. I am trying to figure out how to tell paperclip not to output anything if there is no record in the table so that I don't have broken image links everywhere. How, and where, do I do this?
Here is my code:
class Post < ActiveRecord::Base
has_attached_file :photo, :styles => { :small => "150x150"}
validates_presence_of :body, :title
has_many :comments, :dependent => :destroy
has_many :tags, :dependent => :destroy
has_many :ugtags, :dependent => :destroy
has_many :votes, :dependent => :destroy
belongs_to :user
after_create :self_vote
def self_vote
# I am assuming you have a user_id field in `posts` and `votes` table.
self.votes.create(:user => self.user)
end
cattr_reader :per_page
@@per_page = 10
end
View
<% div_for post do %>
<div id="post-wrapper">
<div id="post-photo">
<%= image_tag post.photo.url(:small) %>
</div>
<h2><%= link_to_unless_current h(post.title), post %></h2>
<div class="light-color">
<i>Posted <%= time_ago_in_words(post.created_at) %></i> ago
</div>
<%= simple_format truncate(post.body, :length => 600) %>
<div id="post-options">
<%= link_to "Read More >>", post %> |
<%= link_to "Comments (#{post.comments.count})", post %> |
<%= link_to "Strings (#{post.tags.count})", post %> |
<%= link_to "Contributions (#{post.ugtags.count})", post %> |
<%= link_to "Likes (#{post.votes.count})", post %>
</div>
</div>
<%
end %>
