I'm pretty new to rails and seem to be having an issue with the paperclip gem. I installed the gem and it works well in development (localhost:3000) but when I'm running it on the heroku server, for some reason it does not want to attach files, and the app breaks (error 500 page).
Here is the process i ran... I pushed my file to heroku, heroku ran rake db:migrate (to add paperclip migrations), and then I ran heroku restart (to restart the app with new migrations). This did not seem to help.
Here is the code that I have for paperclip:
user.rb model:
has_attached_file :avatar,
:styles => {:small => "70x70>"},
开发者_如何学运维 :url => "/users/:attachment/:id/:style/:basename.:extension",
:path => ":rails_root/public/users/:attachment/:id/:style/:basename.:extension"
validates_attachment_size :avatar, :less_than => 500.kilobytes
validates_attachment_content_type :avatar, :content_type => ['image/jpeg', 'image/png']
edit_form.html.haml view:
= form_for (@user || User.new), :html => { :multipart => true } do |f|
...
.profile_picture.text_field
= image_tag current_profile.avatar.url(:small)
%br
= f.file_field :avatar
Again, for some reason it runs great in development, but breaks down in production. Any pointers would be greatly appreciated... I just cant seem to figure this out and it's pretty frustrating. Thank you so much for your time and any help!
In your model.
has_attached_file :picture,
:styles => {:large => "275x450>"},
:storage => :s3,
:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
:path => "appname/:attachment/:style/:id.:extension"
In s3.yml in your config dir:
development:
bucket: bucketname
access_key_id: key
secret_access_key: key
production:
bucket: bucketname
access_key_id: key
secret_access_key: key
Then go signup for a bucket at Amazon S3: http://aws.amazon.com/s3/
You could be having a few problems. However, the first is that you can not write to the file system on Heroku. You will have to implement a different storage mechanism such as s3. You can read about this limitation here: http://devcenter.heroku.com/articles/read-only-filesystem
