I couldn''t

What am I doing wrong here: select_tag(''website_ids[]'', options_from_collection_for_select(Website.find_all, ''id'', ''name'', params[:website_ids]), {:multiple => true, :size => 5}) It works fine except that it does not display the selected options once the form is submitted (it submits to the same page). The

Hi, I found it a while ago, an add-on to Rails for supporting movable select boxes, but I searched through the wiki and the mailing list and couldnt find what I was looking for. I was hoping someone might know of or remember something about the project. Thanks, Dylan.

I''ve tried the following line in ruby script/console require ''digest/md5'' Both my Mac (Intel iMac) and my Windows box return "false"... Any ideas what could be wrong? I was trying to do the RoR Recipe on page 54 of Chad Fowler''s new (beta) book. -Mark -- Posted via http://www.ruby-forum.com/.

Ok, a bit of a possibly dumb question here. When working on Rails apps and I want to add a few custom class rb files to the project, where exactly should I put them? What folder is the best to place them in that things in the model and controller folder can see and use them? Thanks, - Mark -- Posted via http://www.ruby-forum.com/.

Hi, I know that to make a dropdown box automatically submit when you change the value, you do this: <select ..... onchange="this.form.submit();"> BUT i''ve got an ajax form, and if i do the above trick, it simply reloads the ajax partial into the whole screen, rather than into the div where it is meant to go. I''ve already got it all working so that if you click

I am using nested forms with multiple instances of various of the forms. The problem I cant figure out is how to maintain state for the select between postbacks. I am using ''options_from_collection_for_select'' and in this the last param is to be the selected value, but given the dynamic nature, the value is going to depend on the iteration of the form builder. If I manually force

Hi, I''ve got a form where I change and update the @cost values, I wanted to see a select tag showing all the clients names instead of inserting manually the code in the textbox... to do so I''ve used options_from_collection_for_select on another var @client (setted to find_all on the controller calling this viewer). <select name="client">

image_tag(source, options = {}) Ok, when I want to use an image I added the following code: <%= image_tag "dsf.jpg" options = {[align="right", style="padding-right: 10px; padding-top: 5px;"]} %> However, this doesn''t seem to work, it doesn''t like how I have the "options" part setup.

Hello, I have a page where user can register him/herself to the site. If the user enters something wrong, or leaves blank textboxes, I want to reload the page and tell the user what went wrong. Also the textbox-values the user already entered, should be kept in the textboxes. For example, in my user-controller: if @username.length == 0 redirect_to :action =>

Anyone know of a good (fast) way to encrypt/decrypt uploaded files in RoR? I''ve seen this project: http://ezcrypto.rubyforge.org/ but it only seems to encrypt strings and such.
