    text
    copied!<p>I'm working on a website that allows people who run bed and breakfast businesses to post their accommodations.</p> <p>I would like to require that they include a "profile image" of the accommodation when they post it, but I also want to give them the option to add more images later (this will be developed after).</p> <p>I thought the best thing to do would be to use the Paperclip gem and have a Accommodation and a Photo in my application, the later belonging to the first as an association.</p> <p>A new Photo record is created when they create an Accommodation. It has both id and accommodation_id attributes. However, the image is never uploaded and none of the Paperclip attributes get set (image_file_name: nil, image_content_type: nil, image_file_size: nil), so I get Paperclip's "missing" photo.</p> <p>Any ideas on this one? It's been keeping me stuck for a few days now.</p> <h2>Accommodation</h2> <p><strong>models/accommodation.rb</strong></p> <pre><code>class Accommodation &lt; ActiveRecord::Base validates_presence_of :title, :description, :photo, :thing, :location attr_accessible :title, :description, :thing, :borough, :location, :spaces, :price has_one :photo end </code></pre> <p><strong>controllers/accommodation_controller.erb</strong></p> <pre><code>class AccommodationsController &lt; ApplicationController before_filter :login_required, :only =&gt; {:new, :edit} uses_tiny_mce ( :options =&gt; { :theme =&gt; 'advanced', :theme_advanced_toolbar_location =&gt; 'top', :theme_advanced_toolbar_align =&gt; 'left', :theme_advanced_buttons1 =&gt; 'bold,italic,underline,bullist,numlist,separator,undo,redo', :theme_advanced_buttons2 =&gt; '', :theme_advanced_buttons3 =&gt; '' }) def index @accommodations = Accommodation.all end def show @accommodation = Accommodation.find(params[:id]) end def new @accommodation = Accommodation.new end def create @accommodation = Accommodation.new(params[:accommodation]) @accommodation.photo = Photo.new(params[:photo]) @accommodation.user_id = current_user.id if @accommodation.save flash[:notice] = "Successfully created your accommodation." render :action =&gt; 'show' else render :action =&gt; 'new' end end def edit @accommodation = Accommodation.find(params[:id]) end def update @accommodation = Accommodation.find(params[:id]) if @accommodation.update_attributes(params[:accommodation]) flash[:notice] = "Successfully updated accommodation." render :action =&gt; 'show' else render :action =&gt; 'edit' end end def destroy @accommodation = Accommodation.find(params[:id]) @accommodation.destroy flash[:notice] = "Successfully destroyed accommodation." redirect_to :inkeep end end </code></pre> <p><strong>views/accommodations/_form.html.erb</strong></p> <pre><code>&lt;%= form_for @accommodation, :html =&gt; {:multipart =&gt; true} do |f| %&gt; &lt;%= f.error_messages %&gt; &lt;p&gt; Title&lt;br /&gt; &lt;%= f.text_field :title, :size =&gt; 60 %&gt; &lt;/p&gt; &lt;p&gt; Description&lt;br /&gt; &lt;%= f.text_area :description, :rows =&gt; 17, :cols =&gt; 75, :class =&gt; "mceEditor" %&gt; &lt;/p&gt; &lt;p&gt; Photo&lt;br /&gt; &lt;%= f.file_field :photo %&gt; &lt;/p&gt; [... snip ...] &lt;p&gt;&lt;%= f.submit %&gt;&lt;/p&gt; &lt;% end %&gt; </code></pre> <h2>Photo</h2> <p>The controller and views are still the same as when Rails generated them.</p> <p><strong>models/photo.erb</strong></p> <pre><code>class Photo &lt; ActiveRecord::Base attr_accessible :image_file_name, :image_content_type, :image_file_size belongs_to :accommodation has_attached_file :image, :styles =&gt; { :thumb=&gt; "100x100#", :small =&gt; "150x150&gt;" } end </code></pre>
