Hi all, I have a really really annoying problem that''s driving me nuts with file_field and paperclip and having to upload images everytime a form is edited even though the user is quite happy with the currently uploaded image or loose the previously uploaded image. This seems to be caused by the rails file_field helper not storing the data that has been read in from the db in the sa...

Hi, The documentation doesn''t make it clear why both file_field and file_field_tag are both useful. What is the reason for having two instead of just one of these? Thanks, Peter

All, I have a page where I am allowing the user to specify multiple image files that are related to one HTML document. I want to end up with an array of image files that I can then assign into an array within the controller. I''m trying to set up my file_field correctly but am having trouble. I''m not clear on how "the multiple input tags with the same name turning into an array of parameters" thing works? I''ve tried: <%= file_field(''document'', ''image[]'') %> <%= file_field('&...

Hi! Im developing a simple prototype of an application. It fills an oracle db with data about a file in the filesystem, and save the entire file in a blob along with some metadata. To get the file in the db i use a file_field form helper. All goes well with the radrails-integrated browser, but it doesnt work anymore in firefox. The problem is, firefox seems to cut the pathname from the file. Here is the right hash from radrails: "upload"=> "C:\\Documents and Settings\\All Users\\Documenti\\Web...
