I'm learning about Paperclip: Attaching Files in Rails
I place these code to display image on show.html.erb
<%= image_tag @user.photo.url %>
<%= image_tag @user.photo.url(:thumb) %>
On new page, I browse a file (.png) from my computer and click create. Then I got the error
We're sorry, but something went wrong.
How to solve this problem? Please help!
When I check on development.log. I found these errors:
>Status: 500 Internal Server Error
The system cannot find the path specified

I've been using the paperclip gem for quite awhile, and I think its awesome - So don't lose heart!
Here's a couple of things I can think of:
(1) Could you show us your User model code?
(2) Did you accept PNG files as a valid image file? Something like this:
validates_attachment_content_type:avatar, :content_type => ['image/jpeg', 'image/png', 'image/gif']
Good luck!
It appears that your upload directory is not valid. The message you get is a Windows error message. You need to specify a correct upload path for you pictures in your model. For example:
has_attached_file :photo,
:url => ":style/:basename.:extension",
:path => ":style/:basename.:extension",
:storage => :filesystem
I hope it helps.
