Hi, rails newb here.
I'm trying to make a photo album app with rails. I'm using paperclip,
because I need to upload multiple images at the same time. But when I
upload a picture, paperclip isn't saving it. I'm not getting any errors,
it just doesn't save it. I've gone through multiple tutorials trying to
get one to work, but all of them end up with the same result. All the
functionality that I want without the pictures being uploaded :(
Album Model:
[code]
class Album < ActiveRecord::Base
attr_accessible :name
validates_presence_of :name
has_many :photos, :dependent => :destroy
accepts_nested_attributes_for :photos
end
[/code]
Photo Model:
[code]
require 'paperclip'
class Photo < ActiveRecord::Base
belongs_to :album
has_attached_file :data, :styles => { :medium => "300x300>", :thumb =>
"100x100>" },
:url =>
"/images/photos/:id/:style_:basename.:extension",
:path =>
":rails_root/public/images/photos/:id/:style_:basename.:extension"
validates_attachment_content_type :data, :content_type =>
'image/jpeg', :message => "has to be in jpeg format"
end
[/code]
albums_helper
[code]
<div class="photo">
<p>
<% form.fields_for :photos, photo, :child_index => (photo.new_record?
? "index_to_replace_with_js" : nil) do |photo_form| %>
<%= photo_form.file_field :data %>
<%= link_to_function "delete", "remove_field($(this), ('.photo'))"
%><br/>
<% end %>
</p>
</div>
[/code]
_form.html.erb in views/ablums
[code]
<% form_for @album, :html => { :multipart => true } do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :name %><br />
<%= f.text_field :name %>
</p>
<div id="photos">
<% if @album.new_record? %>
<%= render :partial => 'photo', :locals => { :form => f, :photo
=> @album.photos.build } %>
<% end %>
</div>
<%= add_object_link("New Photo", f, @album.photos.build, "photo",
"#photos") %>
<p><%= f.submit "Submit" %></p>
<% end %>
[/code]
_photo.html.erb in views/albums
[code]
<div class="photo">
<p>
<% form.fields_for :photos, photo, :child_index => (photo.new_record?
? "index_to_replace_with_js" : nil) do |photo_form| %>
<%= photo_form.file_field :data %>
<%= link_to_function "delete", "remove_field($(this), ('.photo'))"
%><br/>
<% end %>
</p>
</div>
[/code]
