Paperclip Geometry NoMethodError

[Marc]

Hi,

I sometimes get an NoMethodError "undefined method `[]' for
nil:NilClass" in vendor/plugins/paperclip/lib/paperclip/thumbnail.rb:
18:in `initialize' when uploading an image.

If uploading works the content of options are:

---
:whiny: true
:quality: 60
:convert_options: ""
:processors:
- :thumbnail
:geometry: 150x150>

and if not:

---
:whiny: true
:quality: 60
:convert_options: ""
:processors:
- :thumbnail

My model configuration is:

has_attached_file :source, :styles => {
:small => {
:geometry => "150x150>",
:quality => 60,
},
:mini => {
:geometry => "35x35>",
:quality => 40,
},
:list => {
:geometry => "64x64>",
:quality => 40,
}
}

I don't know why it somethings works and somethings not trying the
same image.

Please help.

Thanks

Marc

I've got the same problem. It looks like the Paperclip::Style object
is not getting the geometry string on some requests, and I'm having
difficulty tracking down why.

The problem is exaggerated when I try to upload multiple files at
once.

I'm not sure how/why styles are reloading, but I changed style.rb:
18..21 and it's maybe fixed? The original code uses Hash delete to
retrieve values from the definitions.

@geometry = definition[:geometry]
@format = definition[:format]
@processors = definition[:processors]
@other_args = definition.reject {|key,value|
[:geometry, :format, :processors].include?(key)}

I'm uncertain on tests or I'd work on that...

Hi,

Further to this.

I was having the same difficulty when reprocessing files either through the rake task or using reprocess! directly.

Your patch solved that. Thank you.

This was only the case with the new style Hash based styles:

  has_attached_file :file, :styles => { 

      :medium => { :geometry => "300x300>", :format => :png },

      :thumb => { :geometry => "100x100>", :format => :png },

      :page => { :geometry => "800", :format => :png, :source_file_options => '-density 288', :convert_options => '-append' }

    }

Working w/ the legacy styles style worked fine:

has_attached_file :file, :styles => { :medium => ["300x300>", :png], :thumb => ["100x100>", :png], :page => ["800", :png] }

As of the 15th of August 2010 this bug is still present and terribly
painful! paperclip is not suitable for a production environment! Or
devs have to make it clear in the documentation that one should use
the "legacy" styles definition mentioned by Tim.

The fix to clone the hash proposed earlier kinda fixed the problem for
me. I had no time to debug depper into paperclip, but after some
extensive testing I can say, that this is working now.
