I’ve been studying the web this morning and trying to find examples  
where someone has imported photo ‘test data’ using attachment\_fu?  
I’ve tried this in many was using a traditional data migration like  
I’ve done hundreds of times and nothing comes in? Attachment\_fu put a  
record to the database, but there is so supporting file behind it.  
I enclose what my migration looks like for one record.

newrecord = Vendphoto.create(  
:vendor\_id =\> ‘1’,  
:title =\> ‘Add Test Vendphoto 1’,  
:content\_type =\> ‘image/jpeg’,  
:size =\> ‘38414’,  
:width =\> ‘230’,  
:height =\> ‘200’,  
:geo\_lat =\> ‘27.9686’,  
:geo\_long =\> ‘-97.0943’,  
:filename =\> ‘KathyTest.jpg’)  
newrecord.save!  
I ‘presumed’ some of this information by manually adding a photo and  
then looking at the MySQL record that was created. I experimented  
putting the photo in question ‘KathyTest.jpg’ in the \public\images  
and many other places. I load the ‘Vendphoto’ record in the database  
BUT the actual photo doesn’t exist in my \Public\Images\Vendphoto (as  
if I had done this manuall).  
Thank you,  
Kathy

here’s an example of loading images in a migration.

```
 filename = "#{some_path}some_file.gif"
 image = Image.create(:uploaded_data =>

```

ActionController::TestUploadedFile.new(filename, ‘image/gif’))

the trick is using the ActionController:TestUploadFile to simulate a  
file upload request.

Cheers,  
Jodi

Jodi,  
I’m so excited about having the ability to load photos with  
migrations! Thank you for responding. I took your code and modified my  
original routine as shown:

def self.up  
down  
filename = “#{‘c:/temp/’}MollyTest.gif”  
newrecord = Ephoto.create(  
:uploaded\_data =\>  
ActionController::TestUploadedFile.new(filename, ‘image/gif’),  
:eitem\_id =\> ‘1’,  
:title =\> ‘Add Test Ephoto 1’,  
:size =\> ‘1536’,  
:width =\> ‘100’,  
:height =\> ‘69’,  
:geo\_lat =\> ‘27.9686’,  
:geo\_long =\> ‘-97.0943’)  
newrecord.save!  
end

The problem is a I get a "rake aborted! uninitialized constant  
ActionController::TestUploadedFile " message when I try to run the  
migration. Any suggestions are greatly appreciated.  
Kathleen

I just put this here since couldn’t find it anywhere else on the net:

require “action\_controller/test\_process”

def self.up  
…  
end
