[ANN] Wee 0.8.0

ruby-talk
1

Hi,

Wee 0.8.0 is out. Have fun!

Major changes are:

  • Ajax support (live updates). See examples/ajax/ajax.rb.

  • FastCGI adaptor (working but not fully tested)

  • Fixed bug in callback processing.

For example, you can update a field with Ajax like this:

def render
r.div.id(‘field’)
r.anchor.onclick_update(‘field’) { update_field }.with(‘Click here’)
end

def update_field
send_render_response {
r.text “Live update works!”
}
end

More? http://rubyforge.org/projects/wee

Regards,

Michael

That is great news. Is there some configuration needed? When I tried the
ajax.rb I got the 1st page fine, but when I click on the "Helloooo" I got:
undefined method `+' for
nil:NilClassC:/ruby/lib/ruby/gems/1.8/gems/wee-0.8.0/examples/ajax/ajax.rb:2

Great news too!

For example, you can update a field with Ajax like this:

  def render
    r.div.id('field')
    r.anchor.onclick_update('field') { update_field }.with('Click here')
  end

Does this block-form of callback assume continuations? Is the other form:
     r.anchor.onclick_update('field', :update_field }.with('Click here')
the non-callback version?

Thanks!

Any idea what might be causing my wee rdoc to not appear (alongside the rdoc
for other gems in gem_server) in this version? It was there for previous wee
gems. It could be I did something foolish (I did remove some wee directories
I found in my regular non-gem ruby lib directories prior to gem-installing
0.8.).

Thanks.

How does one update multiple DOM nodes in a single liveUpdate?

Thanks.

Oops, sorry. @live_updates is not initialize... use this patch:

--- ajax.rb (revision 602)
+++ ajax.rb (working copy)
@@ -20,7 +20,7 @@

   def update

     r.anchor.onclick_update('field', :update_field }.with('Click here')
the non-callback version?

No, both do not involve continuations! The non-block form (:update_field) is
only for people that want to marshal the component state... blocks can't be
marshalled whereas symbols can.

Good question. No problem from the Wee side, but I am not good enough in
Javascript to implement this. What I thought is, that Wee would generate a
document like:

.... content ....
..... content ....

This would update the DOM nodes id1 and id2 with the content.

Anyone willing to hack this in javascript?

Michael

Simply because I did not generate the rdoc files for 0.8.0 (I had some not yet
ready-to-commit files in my tree that I did not want to show up). You can do
this yourself if you like with "rake rdoc".
