Gi,

Im attempting to use the file column plugin, but having a few problems.

In quote.rb I have  
class Quote \< ActiveRecord::Base  
file\_column :image

has\_one :project  
end

then In my \_form.rhtml, I have

Quote file  
\<%= file\_column\_field "quote", "image" %\>

However im gaining this error message, is there somthing I hneed to  
place in quotes\_controller to get this to work? or any other suggestions  
to what could be going wrong?

NoMethodError in QuotesController#new

undefined method `file\_column’ for Quote:Class

well fixed that error by re-starting the server!!

but when i submit the form with a url I now get this error

TypeError in QuotesController#create

Do not know how to handle a string with value ‘tests.doc’ that was  
passed to a file\_column. Check if the form’s encoding has been set to  
‘multipart/form-data’.

Also make sure you have a :string/varchar field called “image” in the  
quotes table of your database.

yeah thanks, got it set a text field, but seems to work

looks like i was forgetting to set the multipart

\<%= form\_tag ({:action =\> ‘create’}, :multipart =\> true) %\>
