The question is, should we deal with Controller and Action logic in the RJS file? If so, is it quite "spaghetti-like"? This is actually for the Agile Web book Shopping Cart example: If the user clicks "Remove Item" and we do it the AJAX way, what if we want to first show the cart''s content as 0 x Pragmatic Version Control $0.00 and then highlight

"The no-framework PHP MVC framework" http://toys.lerdorf.com/index.php?url=archives/38-The-no-framework-PHP-MVC-framework.html Yuck! What spaghetti code. I can''t ever imagine preferring that to Rails. Joe -- Posted via http://www.ruby-forum.com/.

I''ve read AWDR and especially the part concerning adding child line_items to an order. Unfortunately I want to do my process in reverse and in doing what I thought would work I get a null object error when trying to append the children to the parent. This is a _major_ stumbling block in my Rails use as almost every one of my projects has needed this so its a pretty vital problem I need

Here is the schema that I am working with: courses -> courses_teachers <- teachers I want to ensure that a teacher is not assigned the same course more than once. In other words, if I''m in the courses_teachers table as teaching Spanish 101, if someone tries to add that same teacher/course combination to the table again, it will not be allowed. I thought I could use something

I''m currently doing all of this just to have a drop-down list of Courses for a particular student: ===== edit template ===== <%= f.select :course, @courses, :selected => @student.course.id %> =================== ===== students controller ===== def edit @student = Student.find(params[:id]) @page_title = "Edit #{@student.full_name}" @courses =

Hi all. Got a stupid-simple question about associations. I have two models - school and course. There are a fixed number of schools (set up in the migration). Each course is assigned a school and a school will be associated with multiple courses... How do I set up the associations? Do (can) I have School :has_one :course and Course :has_many :schools? Does the schools table then get a course_id

Hello Friendly Gurus, I have a volunteers table and an hours tables. I''ve edited the respective models to have: "hours belongs_to :volunteer" and "volunteers has_many :hours". My problem is, I don''t know how to set the volunteer_id column in the hours table to the appropriate value so that hours will belong to volunteers. I''ve added the

Greetings, I am new to R. Right now I'm most interested in the spaghetti plots of achievement over time by student ID associated with longitudinal analysis. How can I do a spaghetti plot of all students, but color the lines by group membership such as gender or race, and indicate this color scheme in the legend? Any advice would be much appreciated.

I''m having difficulty understanding how to make validation of facade columns consistent with validation of other active record columns. To illustrate this, I''m going to extend the facade column example discussed on pp. 284-5 of AWDR. Let''s say that there is a "rectangles" table that has width and height columns. For some unknown reason, width is stored in

I followed the sample code in AWDR 2 like this: store_helper.rb def hidden_div_if(conditions, attributes = {}) if conditions attributes["style"] = "display:none" else attr = tag_options(attributes.stringify_keys) "<div #{attr}>" end end store.html.erb <%= hidden_div_if(@cart.items.empty?, :id => "cart") %> <%=

I''m stumped on what seems like should be a fairly easy thing, so I hope someone can point out my error. I wanted to show a few things on every page, so I added an application level template in "layouts". I added my styles in there, and put the controller name and action name into the TITLE tag for my own reference. So far so good - works like expected. Then I wanted to

I''m trying to use counter_cache, but I''m not doing something right. It is unreliable and I keep having to correct it manually. Is there a good tutorial or reference on how to use it on-line? I have the AWDR book, but I need something more complete. TIA, Jeffrey
