similar to: Current date/time - how to store with comments?

I want to append "#comment-1" or whatever, depending on the id to the end of my xml.link(" ... /#comment-1") attribute in my generated xml. Well, when I put: xml.link(" ... /#comment-" + comment.id) I get an Application error (rails) message when I look at the generated XML. This is what I''m doing without the id on the comments (its working fine):

How can I have the page redirect_to the same page after someone posts a comment? 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

If I were to figure out how to develop an RSS feed for my blog, I should be able to test that locally right? If I go to http://mydomain.com/posts/feed/, what should I see? The XML output? Thanks! -- Posted via http://www.ruby-forum.com/.

Does anyone know how to get going with the flickr api WITHOUT using the ''flickr.rb'' gem? I''m wanting to just use the REXML and ''net/http'' stuff.

When a user posts a comment on my site, is there a way for me to be notified via email? I know this is pretty easy in php, i.e. mail() function, but I''m looking for the equivalent in Rails. Thanks! -- Posted via http://www.ruby-forum.com/.

I''m trying to automatically fill a "posted_by" text by with whoever is logged into the session. How do you set the value attribute using "<%= text_field ... %>"??? I''ve tried: <%= text_field ''post'', ''posted_by'', ''value'' => User.find(session[:user_id]).name.capitalize) %> But I get

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.

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

This is how I''m posting comments currently. This works, but I read somewhere that I shouldn''t inject params right into my sql query, because it makes it easy for people to hack in and ruin the db. I''m not sure if this even makes sense, but I''ve tried other things, and can''t get anything else to work. #currently def comments content =

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,

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?

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?

Hi!

With a has_one/belongs_to relationship, what''s the best way to guarantee that the belongs_to object gets created and is accessible alongside the has_one object? I *think* the after_create callback is a good choice, but I discovered an oddity while trying it.

Anyone have an idea on this? Got a weird situation where on a specific model I can not create an instance using params, yet it works fine on other models.
