This doesn''t make any sense to me anymore. I have an Upload that belongs_to a Comment. Within my Upload model I expect to be able to access the associated comment with comment.foo. I can only seem to do this AFTER validation. I''m assuming before_create takes place between validation and updating the database, because when I try to access comment.foo within the validate

I''m working on a simple CMS. The main data type are "listings" a listing habtm (has_and_belongs_to_many) categories and subcategories. Subcategories belong_to categories.

I''m trying to read image data from an upload file field directly into an RMagick image object without having to temporally save the image file first. Assuming my file field param is assigned to @temp_file, i tried RMagicks from_blob method: img = Magick::Image::from_blob(@temp_file.read) But i get an error message saying that the blob is empty. I also tried feeding it the entire

I''ve been doing a lot of testing witn RMagick lately, in view of reports that it leaks memory. I''m happy to report that RMagick doesn''t seem to leak at all, when used as directed -- that is, when you remember to set the image variable to nil and call GC.start manually after you''re done with an image. BUT -- one ImageMagick format seems to be leaky! I was

Hi! I''ve got 2 tables: products and images. Product has_many images, image belongs_to product. In images table i store product_id and name of the image (not the image itself).

Hi there, I''m writing a little application that parses an image file and extracts the camera settings from the file (the EXIF data) and saves all the fields to the database.

The picture is stored on the file

Hi, I need to take a single uploaded image file and save three resized versions of it, a thumbnail, normal and large version. I was planning on doing this in my model by having an array of geometry strings and looping through them, each time saving a new image object resized to the correct geometry. I know that file column does similar stuff, but I would prefer to have a separate database row

I have two problems. I have a comment that has_many uploads. Before saving the comment, I want to be sure that the upload(s) has passed validation, but I also need to validate in other ways.
