Hi All I''m getting the following very strange Ajax error and I''ve searched Google, this group and various other places to no avail. So I''m desperately hoping someone here can help.

I have created a controller that shows paged blog entries, and below each blog is a list of comments along with a form alowing the user to add a new comment. To create the form for the comment entry I used form_for

I am starting to play with validations as I want to catch errors before SQL rejects inserts to the table which are ugly when nulls are sent to ''Not Null'' columns, etc. If I do something in my model like... validates_format_of :first_name, :with => /^\w+$/, :message => "you moron, enter a name" I still end up

With the help of several heroes here yesterday I beat my way into a working solution to adding comments to one or more models in my application using acts_as_comentable. Great plugin, but my implementation is lame. I need enlightenment. I have users who log in. For several views I want to let them add comments. Enter act_as_commentable which does just this -- it''s polymorphic, so you

How does one deal with validation error messages on child objects of the main model object behind a page? I have the basic blog w/ comments page (only my "entry" is a "proposal"). I have the comments saving just fine, but I wanted to show an error if the user hits the submit button without typing anything in the comment. I added "validates_presence_of

In my blog a user can add comments. I want an Ajax call to add the comment to the bottom of the comments list. How to i return a comment thats is in the comment template and add it to the bottom of the page. I have gotten as far as rendering some text back to the form and the comment doesn''t display until i refresh. This is my _newcomment.rhtml form to create a new comment <div

Hi all, I want to execute certain ruby script periodically in my rails application running on windows platform.

I'm trying to write comment writer thing for zinf, because I love the program, but it doesn't fully support ogg. I've found how to read comments, but can't figure how to write them.

Hi, I am using R in one of my courses. I am trying to use R's linprog package to solve to formulate 2-class classification problem as Linear programming problem. For my formulation, I need to set to "cvec" to all 0s. I know the points are linearly separable so an optimal solution "x" does exist, which satisfies all the constraints.
