State_models plugin and file_column?

Rails
1

I was looking at Kyle Mawell’s extremely nifty-looking StateModels
plugin

http://www.kylemaxwell.com/articles/2006/02/06/fun-with-single-table-inheritance

and before I go down the road with it, I was wondering if anyone has
used it with file_column.

The way file_column deals with an uploaded file – by storing it to the
filesystem in a path that employs the model name and id – sounds like
it might break against this.

Thanks.

You can hardcode the path in the base class.

class MyModel < ActiveRecord::Base
file_column :my_field, :store_dir => :some_method
def some_method
“my_model/my_field”
end
end

Hi Kyle,

I too am interested in doing this for my application, so I created a new
rails app, loaded the database schema, added the changes to
conf/environment.rb and generally followed your instructions to the
letter. When I post a page (or do anything other than render HTML, for
that matter) I get the error below. What have I done wrong? :frowning:

I am using Rails 1.1.2 with Ruby 1.8.4, if that helps…

TIA,

Matt

I was curious about whether you knew if a file_column field filled on
page one of a multipage form would still be there and save properly when
page 3 was submitted.

I don’t think this below is quite what I meant unless this is a fix you
already found you needed to make yourself, but I guess it won’t hurt
for me to set up a test app and see if StateModels and FileColumn play
well together myself. Either you have indeed got it working or you’re
pretty confident it will. These are Good Signs. :slight_smile:

Thanks.

Someone told me that Rails 1.1 wants the models to be in different
files, I believe. If you require_dependency “model_file_name” (no
.rb) in your config/environment file, you should be fine. Tell me
if that doesn’t work and I’ll look into it in detail.

File_column will still be able to find the previously saved file, but
updating it will do funny things, unless you follow the hard-coding
suggestion in the previous email.
