errors creating thumbnails

[shenry]

I'm having trouble creating thumbnails ... I've got whiny_thumbnails
set to true (if I don't explicitly set this it doesn't complain when
the thumbnails fail) and <%= f.error_messages %> in my form.

When I attempt an upload/resize I get the following error:

ActionView::TemplateError (can't convert Array into String) on line #2
of photos/_form.html.erb:
1: <% form_for @photo, :html => { :multipart => true } do |f| -%>
2: <%= f.error_messages %>

Any ideas on how to get the error messages to display so I can figure
out why it's not resizing the thumbnails?

Thanks,

Stu

You could try f.error_messages.inspect, but it won't be as pretty.

That returns the same "can't convert array to string" error

[Jonathan Yurek]

Really? Then something else is wrong, because #inspect on an Array
returns a String.

Thanks for your help on this, Jon. It seems like it's hanging up
before it even hits the #inspect, here is the stacktrace:

ActionView::TemplateError (can't convert Array into String) on line #2
of photos/_form.html.erb:
1: <% form_for @photo, :html => { :multipart => true } do |f| -%>

2: <%= f.error_messages.inspect %>

am I correct in believing that the + method in validations.rb is
throwing the error as it's building the array of errors? This error is
happening while running on heroku which has RMagick and ImageMagick
installed on their system, so I'm not sure if paperclip knows how to
find those resources and therefore not creating thumbnails and
throwing the exception?

Also, I only get these exceptions if I explicitly set whiny_thumbnails
=> true or validates_attachment_thumbnails :photo ... shouldn't
paperclip default to whiny_thumbnails => true? I've got the plugin v.
2.1.5

Thanks again,

Stu

I believe the error causing the thumbnail failure is:

/tmp/stream.24992.0 is not recognized by the 'identify' command

any ideas? Thanks,

Stu

from the console of the heroku app:

>> identify /tmp/stream.24992.0
SyntaxError: compile error
/home/heroku_rack/lib/init.rb:1: unknown regexp options - tra
/home/heroku_rack/lib/init.rb:1: no .<digit> floating literal anymore;

/home/heroku_rack/lib/init.rb:1: syntax error, unexpected tFLOAT

Not sure if this is helpful or not in figuring out where the issue
might be... any help is appreciated.

That's... weird. Is it trying to run the identify command as ruby?
That's what it looks like it's trying to do.

Have you contacted heroku support about this at all?

[Josh Schairbaum]

FWIW, I am receiving this same error on my Mac. I followed the
directions on the RMagick page to install ImageMagick from ports, and
I believe I've had it work before w/ paperclip. My app is running
passenger.

[paperclip] Paperclip attachment picture on Photo initialized.
[paperclip] Assigning #<File:/tmp/CGI.57760.2> to picture
[paperclip] Writing attributes for picture
[paperclip] Post-processing picture
[paperclip] Processing medium #<File:0x5791224> in the thumbnail
processor.
[paperclip] An error was received while processing:
#<Paperclip::NotIdentifiedByImageMagickError: /tmp/stream.57760.0 is
not recognized by the 'identify' command.>

Running the identify command on the original file returns the proper
value.

Josh

I'm running on OS X with Passenger and it works fine. Don't have full
thread history, so it's probably been mentioned before by me or
someone else, but did you try configuring the full ImageMagick path?
Has been mentioned several times before on the list, search for more
info.

Happy new year!

[shenry]

Thanks for the replies, everyone.

Ive got this working fine on my mac, it's just on the heroku deploy
that the problem arises. I've contacted them regarding to problem too.

Happy new year!

Henrik,

I can set it explicitly, but I was trying to set it dynamically and it
was failing. For example, in RAILS_ROOT/config/initializers/
paperclip.rb:

image_magick_path= `/usr/bin/which identify`.strip.chomp("/identify")
Paperclip.options[:command_path] = image_magick_path

Passenger chokes on the `which` command, of course it works from the
console, and I would assume also mongrel, which I think runs as me.
It's not a public project, so I can just set it explicitly.

Regards,
Josh

No big wonder -- `which` searches the PATH :) And the reason you need
to set the IM path explicitly is that it wasn't there.
