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]

Try creating a photo manually, so in script/console type:
Photo.create(:data => File.new("/path/to/a/file"))
Also check the rails log file for any warning/error message, beware it
can be hard to spot in all the lines that get printed.

Photo.create(:data =>
File.new("/home/kaspir/Pictures/backgrounds/bg.png")
didn''t return anything.
this is my development log error, although I''m not exactly sure what it
means.

There is a WARNING message in the log. Can''t see it? I told you it was hard to spot. So to solve your problem or at least move a step forward, change Album so that it reads: attr_accessible :name, :photos_attributes -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
