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](http://adress/employee_public/pictures/0000/0010/not.gif)” it takes the  
uri “[http://adress/pictures/0000/0010/not.gif](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](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:

module Backends

74. end

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.
