Hi folks,
i''m new to ROR. My Application works fine on my local machine, but if i
deploy my application the pictures and files are not shown correctly.
Instead of taking the right uri
"http://adress/employee_public/pictures/0000/0010/not.gif" it takes
the
uri "http://adress/pictures/0000/0010/not.gif" like on my local
machine,
where the paths looks like this:
http://localhost:3000/pictures/0000/0010/not.gif
I use attachment_fu for handling uploads.
Everything in the application works fine, except the images and files.
Where is the problem. My server runs Apache/2.2.3 (Debian) mod_jk/1.2.26
Phusion_Passenger/2.0.3 PHP/4.4.4-8+etch6 mod_ssl/2.2.3 OpenSSL/0.9.8c
My file_system_backend.rb:
1. require ''ftools''
2. module Technoweenie # :nodoc:
3. module AttachmentFu # :nodoc:
4. module Backends
5. # Methods for file system backed attachments
6. module FileSystemBackend
7. def self.included(base) #:nodoc:
8. base.before_update :rename_file
9. end
10.
11. # Gets the full path to the filename in this format:
12. #
13. # # This assumes a model name like MyModel
14. # # public/#{table_name} is the default filesystem path
15. # RAILS_ROOT/public/my_models/5/blah.jpg
16. #
17. # Overwrite this method in your model to customize the
filename.
18. # The optional thumbnail argument will output the
thumbnail''s filename.
19. def full_filename(thumbnail = nil)
20. file_system_path = (thumbnail ? thumbnail_class :
self).attachment_options[:path_prefix].to_s
21. File.join(RAILS_ROOT, file_system_path,
*partitioned_path(thumbnail_name_for(thumbnail)))
22. end
23.
24. # Used as the base path that #public_filename strips off
full_filename to create the public path
25. def base_path
26. @base_path ||= File.join(RAILS_ROOT, ''public'')
27. end
28.
29. # The attachment ID used in the full path of a file
30. def attachment_path_id
31. ((respond_to?(:parent_id) && parent_id) || id).to_i
32. end
33.
34. # overrwrite this to do your own app-specific
partitioning.
35. # you can thank Jamis Buck for this:
http://www.37signals.com/svn/archives2/id_partitioning.php
36. def partitioned_path(*args)
37. ("%08d" % attachment_path_id).scan(/..../) + args
38. end
39.
40. # Gets the public path to the file
41. # The optional thumbnail argument will output the
thumbnail''s filename.
42. def public_filename(thumbnail = nil)
43. full_filename(thumbnail).gsub
%r(^#{Regexp.escape(base_path)}), ''''
44. end
45.
46. def filename=(value)
47. @old_filename = full_filename unless filename.nil? ||
@old_filename
48. write_attribute :filename, sanitize_filename(value)
49. end
50.
51. # Creates a temp file from the currently saved file.
52. def create_temp_file
53. copy_to_temp_file full_filename
54. end
55.
56. protected
57. # Destroys the file. Called in the after_destroy
callback
58. def destroy_file
59. FileUtils.rm full_filename
60. # remove directory also if it is now empty
61. Dir.rmdir(File.dirname(full_filename)) if
(Dir.entries(File.dirname(full_filename))-[''.'',''..'']).empty?
62. rescue
63. logger.info "Exception destroying
#{full_filename.inspect}: [#{$!.class.name}] #{$1.to_s}"
64. logger.warn $!.backtrace.collect { |b| " > #{b}"
}.join("\n")
65. end
66.
67. # Renames the given file before saving
68. def rename_file
69. return unless @old_filename && @old_filename
!full_filename
70. if save_attachment? && File.exists?(@old_filename)
71. FileUtils.rm @old_filename
72. elsif File.exists?(@old_filename)
73. FileUtils.mv @old_filename, full_filename
74. end
75. @old_filename = nil
76. true
77. end
78.
79. # Saves the file to the file system
80. def save_to_storage
81. if save_attachment?
82. # TODO: This overwrites the file if it exists, maybe
have an allow_overwrite option?
83. FileUtils.mkdir_p(File.dirname(full_filename))
84. File.cp(temp_path, full_filename)
85. File.chmod(attachment_options[:chmod] || 0644,
full_filename)
86. end
87. @old_filename = nil
88. true
89. end
90.
91. def current_data
92. File.file?(full_filename) ? File.read(full_filename) :
nil
93. end
94. end
95. end
96. end
97. end
And my helper function for showing the pictures looks like this:
1. def picture_for(employee, display_height = nil, img_size = :small)
2. if employee.picture
3. picture_image = employee.picture.public_filename(img_size)
4. link_to(image_tag(picture_image, :height => display_height),
employee.picture.public_filename)
5. else
6. image_tag("employee_portrait.gif", :height =>
display_height)
7. end
8. end
If you need more infos, write me please. I''ll appreciate any help.
