Instance Method Details

#upload_column_field(object, method, options = {}) ⇒ Object

Returns an input tag of the “file” type tailored for accessing an upload_column field (identified by method) on an object assigned to the template (identified by object). Additional options on the input tag can be passed as a hash with options.

Example (call, result)

upload_column_field( :user, :picture )
  <input id="user_picture_temp" name="user[picture_temp]" type="hidden" />
  <input id="user_picture" name="user[picture]" size="30" type="file" />

Note: if you use file_field instead of upload_column_field, the file will not be stored across form redisplays.
