Rails - Mar 2006 - How to handle errors - HELP

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?

Here''s my controller:


def comments
    content = Content.find(params[:id])
    @comment = Comment.new(params[:comment])
    content.comments << @comment
    content.save
    @comment.save
    @comment_count = Comment.count("content_id=#{params[:id]}")
    render_without_layout
end



If the comment is blank, then do I want to rescue the nil, then "render 
:text => ''Please fill out the fields.''"?  Then in my
remote form
options, on the :update, I could have:

:update => {:success => ''the_right_div'',:failure =>
''error_div''}

????

This is how I interpret the overall process, but I don''t know the 
correct syntax on how to do this with the resue, and what I check for.

I just want nothing to happen when the user clicks the "submit
comment"
button when there''s nothing to submit.

Please HELP!

Thanks in advance for any tips - this forum has really helped me out!

Hi !

> def comments
>     content = Content.find(params[:id])
>     @comment = Comment.new(params[:comment])
>     content.comments << @comment
>     content.save
>     @comment.save
>     @comment_count = Comment.count("content_id=#{params[:id]}")
>     render_without_layout

#save returns true if it was able to save.  So, you need to do
something like this instead:

if @comment.save then
  # what you have above
else
  # render another view, saying there was one or more errors
end

Hope that helps !
