I’m trying to use attachment fu to add a large number of images at  
once using a script but i can’t even get it to add an image from the  
console… the other documentation i’ve found no longer seems to work.

Something like this doesn’t work properly

c = Image.new  
c.content\_type = ‘image/jpeg’  
c.filename = ‘test.jpg’  
c.discussion\_id = 7330  
c.uploaded\_data = File.open(’/Users/holden/Desktop/pictures/  
LionsFW.jpg’)  
c.save

It does save… but the file doesn’t get populated.

All the previous documentatio circa 2007 says :temp\_file but this is  
no longer available to i tried switching it to :uploaded\_data, but  
that doesn’t seem to work either…

also it want’s the size and is a required field, but shouldn’t this be  
automatically deduced… providing it doesn’t help either…

Any suggestions would be a great help,

Thanks,

holden

Here’s how I’m doing it:

```
    file = ActionController::UploadedStringIO.new( data ) #this is

```

the real data  
file.instance\_variable\_set( ‘@original\_filename’,  
“#{rand(1000)}\_#{filename}” )  
file.content\_type = i.content\_type

```
    i.uploaded_data=( file )
    i.save!

```

You can try with the example in the attachment\_fu home (http://  
[GitHub - technoweenie/attachment\_fu: Treat an ActiveRecord model as a file attachment, storing its patch, size, content type, etc.](http://github.com/technoweenie/attachment_fu/tree/master)):

i.uploaded\_data = ActionController::TestUploadedFile.new(file\_path,  
mimetype)

I tried using ActionController::UploadedStringIO.new( data )

and it does create the files… but the images don’t work.

Is data supposed to be the filepath? ie. photos/joe.jpg ?

I also found an example of exactly what I want to do in the Practical  
Rails Plugins book, but which is outdated using “temp\_data =” It  
looks simple and perfect, what am I missing?

nevermind found this lurking in the documentation… i suppose i  
should have read it better before looking else where… ;-(

#!/usr/bin/env ./script/runner

# required to use ActionController::TestUploadedFile

require ‘action\_controller’  
require ‘action\_controller/test\_process.rb’

path = “./public/images/x.jpg”

# mimetype is a string like “image/jpeg”. One way to get the mimetype

for a given file on a UNIX system

# mimetype = `file -ib #{path}`.gsub(/\n/,"")

mimetype = “image/jpeg”

# This will “upload” the file at path and create the new model.

@attachable = AttachmentMetadataModel.new(:uploaded\_data =\>  
ActionController::TestUploadedFile.new(path, mimetype))  
@attachable.save
