Paperclip don't generate styles and original image appears as broken - ruby-on-rails

Question

I having a big issue here. I really tried, but I can't solve this problem by myself, so I hope people can help me here.
Before talk about my problem, I must say I'm using Paperclip and IMGKit in my Project, but I think the problem is with Paperclip.
I create a Rails Task to take snapshots from the home page of some sites. Sometime ago everything is working fine, but now everything goes down. I import my real database from Heroku to localhost (without any images and migrations of paperclip), run the migrations, delete all old files from 'public/system' and run my task again (to take snapshot of all websites).
So, now I have:
The paths and original images are generated, but when I try to load them in View, this just show as a broken image.
Paperclip doesn't generate the path and converted images of :styles.
Sites that don't have image, I can see my default image correctly.
ImageMagick seems to be working, I try convert some images and worked like a charm.
Let's take a look at the code. Assume that I'm running a task that will perform this task to all sites in my database. The sites are called "items" in my architecture.
Development.rb
#config/environments/development.rb
# "which convert" give me this path
Paperclip.options[:command_path] = "/usr/local/bin/"
Item.rb (model)
My task just call "object.save" of every site in the DB, so my code starts on before_save.
has_attached_file :image,
:styles => { :small => "200x147#" },
:convert_options => { :small => "-quality 75 -strip" },
:default_url => '/images/:style/bitcoin-earth.jpg'
before_save :generate_data
def generate_data
self.image = get_image(self.id, self.url_original)
end
# Take snapshot of the website
def get_image(filename, link)
kit = IMGKit.new(link.to_s, :quality => 100, :width => 1024, :height => 768)
file = Tempfile.new(["template_#{filename}", 'png'], 'tmp',
:encoding => 'ascii-8bit')
file.write(kit.to_img(:png))
file.flush
return file
end
View
<%= image_tag store.image.url %>
Gemfile
gem "paperclip"
If I try to run rake paperclip:refresh:missing_styles, the task finish very fast without any error. But if I try to run rake paperclip:refresh CLASS=Item I got:
Image Paperclip::Errors::NotIdentifiedByImageMagickError
And yes, I already search for it and I didn't found a solution for my case.
A little tip?
When I "inspect element" in my project and try to see the source of the item image, I saw:
http://localhost:3000/public/system/items/images/000/000/216/original/template_21620140109-14507-1c0yszzpng?1389305824
But if I go to my project folder, I just see a image called template_21620140109-21209-1yls03opng. Note that doesn't exist any "?1389305824" there. See the image above.
Well, I think that's it. What can be the problem? I really need solve this issue, please, help me :/

Item.rb (model):
before_save :generate_data
def generate_data
file = File.open(get_image(self.id, self.url_original))
self.image = file
file.close
end
def get_image(filename, link)
kit = IMGKit.new(link.to_s, :quality => 100,
:width => 1024, :height => 768)
file = Tempfile.new(["template_#{filename}", '.png'], 'tmp',
:encoding => 'ascii-8bit')
file.write(kit.to_img(:png))
file.flush
return file
end
Now I don't have any error on console while getting images and saving on DB, but Paperclip still don't generate my :styles. When I go to log/development.log, I can see this error, but I don't know what I can do to solve:
Command :: file -b --mime 'tmp/template_24320140110-17577-80zj1c.png'
Command :: identify -format '%wx%h,%[exif:orientation]' '/tmp/template_24320140110-17577-80zj1c20140110-17577-mqa2q3.png[0]'
[paperclip] An error was received while processing: #<Paperclip::Errors::NotIdentifiedByImageMagickError: Paperclip::Errors::NotIdentifiedByImageMagickError>
I think we're getting closer, please, keep helping me :)

Answer 1

I think your problem is here:
template_21620140109-14507-1c0yszzpng?1389305824 #-> should have .png (not a valid image)
Image
This might not be the problem, but maybe you could streamline your method to exclude the temporary file:
# Take snapshot of the website
def get_image(filename, link)
kit = IMGKit.new(link.to_s, :quality => 100, :width => 1024, :height => 768)
file = kit.to_file("system/temp/template_#{filename}")
return file
end
I think the issue is that ImageMagick is not being passed a "real" file, and consequently you're getting the unrecognized image issues
