using attachment fu in masse

rubyonrails-talk

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

Something like this almost work...

Discussion.new (:name=>"test2", :location_id=>"1036", :image_attributes=> [{ :uploaded_data=> File.new("/Users/holden/Desktop/pictures/ LionsFW.jpg") }], :website=>"testdsfdf", :geo=>"", :phone=>"test", :blurb=>"testdsfsdfsdf", :address=>"test", :hwID=>"test", :email=>"test@aol.com")

undefined method `' for #<File:/Users/holden/Desktop/pictures/ LionsFW.jpg

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!

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I also found an example of exactly what I want to do in the Practical Rails Plugins book, but which is outdated using "temp_data =" It looks simple and perfect, what am I missing?

You can try with the example in the attachment_fu home (http:// github.com/technoweenie/attachment_fu/tree/master):

i.uploaded_data = ActionController::TestUploadedFile.new(file_path, mimetype)

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
