I''m having trouble with my Ajax comments, but only when someone clicks the submit button when there''s no comment. How can I handle this in my code? Do I use "rescue nil" or something?

I know that you can do "redirect_to :action => ''index''", but the page is located at this URL: /posts/2006/02/01/individual_post/ So, the action is "individual" which is in the "posts" controller, but there is a custom URL mapped for the URL shown above. How can

I''m trying to post comments using Ajax. It seems that I have an infinite loop somewhere, because it hangs on the return from the Ajax call. The comment does get saved to the DB, but I have to refresh the page for it to show. The reason I know it''s some sort of infinite loop, is because I''m showing a "loading.gif" image, and it never goes away. Plus, if

I''m working on uploading my site to dreamhost. I just setup my production database, and gave it a host name. It said that it was successfully created.

I have implemented the standard blog and comments app from the screencast. However I am trying to extend the functionality. I want to be able to display a list of posts and order them by the total number of comments

Ok, my site is setup like pretty much every other blog out there. A list of the most recent 5 posts, then by clicking one, you go to an individual post page, displaying the full context of that post. Now, what I would like to do is to display the related entries in the side column, which is part of the layout, based on the tags belonging to that specific entry. Here''s my coding so

How do I include all incoming URL parameters (i.e. list_content.rhtml?content_id=23) in my link_to statements?

After I attempted to add ActionMailer functionality, it gave the "Application error (Rails)" and now, everything on my site works, except for the part where the Actionmailer ''would have'' sent the email. I took that out now, re-uploaded the file, and ran "killall -USR1 dispatch.fcgi" and still nothing. Everything else works, except that. Any idea what

I haven''t had a chance to upload my app and configure dreamhost, but I did log in and create the folder using the "rails app_name" command. Now, my question is, I read online to do this: > cd domain.com > rails my_app_name So, I did just that. Rails will know what to do even though my application is in a sub-directory under "domain.com"? Essentially,

When someone comments on my site, I would like to store the user''s name as a cookie, and display it the next time they return. I really don''t know how to do this. Does this use the cgi library?
