Hi, 1. How to resize an image uploaded by a web form before saving it to the disk? (i need all uploaded images to have similar size) 2. How to create thumbnails? Is it enough if i specify small size of the image in html or would the image look horrible? Can i do it somehow in ''realtime'' using javascript?

Hi! File_column plugin saves uploaded files to "public/model/image/model_id/filename", if i understand it correctly. Does it mean that it creates new folder for every image?

Hi! The topic can be a bit misleading, because it may suggest that i want to change css style.

Hi! I''ve got a form for creating news and i''d like to keep formatting of the text in the textarea - if user presses enter twice, or presses space ten times it should be visible when editing or showing the news. Probably i should add before_save filter and some regexps for adding html tags, but i know almost nothing about regexp. Maybe there''s a simpler way also.

Hi! Is there anywhere on the net a sample of some basic app (with actions like create, edit etc.) that uses single table inheritance? I''m trying to create (my first) app with 2 different types of users and while it basically works, my code is quite messy. I.e. i''ve got 2 forms, each for different type of user.

Hi! If i have an object it''s easy. But i''m making a simple contact form and i check if email address is correct.
