similar to: Creating multiple rows with one form

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). I''ve created a single form, where user can add any number of images for a product he/she is creating (new fields are created using javascript). The images that are uploaded are saved to public/images

does anyone know much about resizing different versions of images with file_column? i tried it and everything works fine, but my question is can you do more than just make sizes with a version of image? i''m working on a photo album and i would like to resize the image to a medium size, but create a thumbnail as well and crop anything left to make the thumbnail a perfect square. --

Hi! Previously i had ruby 1.8.2 (One-Click Ruby Installer) installed, but the rdoc and plugindoc didn''t work, so i decided to install ruby 1.8.4. I had uninstalled ruby 1.8.2 (uninstaller deleted the whole ruby folder with radrails and everything, just great) and installed One-Click Ruby Installer 1.8.4-16 preview3. Then installed rails, rmagick, radrails, created docs for trunk

Below every page in the browser i get: "Loaded suite dispatch.cgi Started Finished in 0.000225 seconds. 0 tests, 0 assertions, 0 failures, 0 errors" I''m not sure if i changed something or someone else did it, but now i don''t know how to get rid of it. It has something to do with testing, right? How to switch it off? -- Posted via http://www.ruby-forum.com/.

Hi! I''m struggling with it for a week. I posted a few similar posts that cleared up few things (thanks Mark!), but i still don''t know how to do it properly. What i''m trying to do is to create parent object and its many children (images - i tried using file_column, but it''s a topic for another post)using data from a single form. I''ve got a working

I''m trying to provide our customers with a page where they can add up to 20 items to their cart in one form. The form simply has 20 rows with each row containing a text input for product code and a text input for quantity. I''ve tried having the controller create an array that has an object for each row by looping through something like: @new_items[1] = Cart.new and the

I have a form that I want to use to update multiple objects. In the controller, @grades = Grade.find(params[:grade].keys) @grades.each_with_index do |grade, i| grade.update_attribute(params[:grade][i]) end all_valid = @grades.inject(true) {|memo, c| c.valid? && memo } this doesn''t update the attributes as I would expect. (I would just use

I am trying to implement the uploading of a file to a remote server I get error while trying to write the file on the server. The error I get is the following: undefined method `rewind'' for #<String:0x2aaaad062eb8> It seems to be treating my file as a string instead of a File object. --------- Code is below ------------------ VIEW: <%=

This is simple (I am sure) but how do you get the id of the inserted element after the element has been save? I thought it was something like this: @product = Product.new(params[:product] if @product.save add_image(product.id, params["image"]) flash[:notice] = ''Product was successfully created.'' redirect_to :action => ''list_products'' end

I just put this up on the wiki, and thought I''d share in case it''s useful to anyone else. This is handy if you don?t want to wrap your input elements inside a div when an error occurs, but instead want to add some sort of CSS style to fields with errors: ActionView::Base.field_error_proc = Proc.new do |html_tag, instance| msg = instance.error_message error_style =

Dear R users, do you know an easy way (other than star plot) of making several points laying one over another visible? Is it any simple way of increasing such "multipoint" symbols - or shifting their positions randomly to make several points in one place visible?

Hi! Uhm are attributes just something like additional members of a class, other than those that come from the names of columns in the table? I''ve got images table, which has ''name'' column. I''ve added support for creating thumbnails out of uploaded pictures and i''d like to have an easy way of accessing them in my views. How to do it? I.e. my image

Does anyone have a good working e-mail validator? or even some regexp to make the validates_format_of work right... that would be awesome. Also, maybe an online tutorial for regexp. i''ve always been afraid of it but i think it''s time to face the fears. thanks! -- Posted via http://www.ruby-forum.com/.

Hi! What is the easiest way to restrict access to some part of the page? In php i just put .htaccess and .htpasswd files in /admin folder and it worked. Now i''ve got one admin folder for controllers, one for views, public folder and i''m not really sure if it''s still possible. So what is the easiest way? I don''t have any user logging features on my site,

I''m trying to use the file_column plug-in to attach a file to a newsletter posting. It works fine if I get the form right the first time, but if I get an error, such as not typing in a required field, and the form re-displays, my file selection box reverts to "no file selected." Here''s my relevant controller code: def new @newsletterpost = Newsletterpost.new
