Merb devel - Dec 2006 - What does js partial(...) do?

In the example application named "sample_app", comment.jerb contains
the following line:

$(''comments'').update(<%=js partial(:comments) %>);

What does the ''js'' method do to/with, if anything at all,
''partial(:comments)''?

Merb is quite fun to use and I''m starting to get a feel for it and
ruby. I''m surprised at how quickly it enables me to create my little
application. Are there plans to make Merb more visible as some other
mini-framework projects have done (thinking of Camping as an example)?

This file in the track holds all a few Java Script goodies:
http://merb.devjavu.com/projects/merb/browser/lib/merb/mixins/javascript_mixin.rb

You should check that file out!

But in there it says:

"calls .to_json on data."

Hence it converts converts the output of partial into JSon from what
"I"
understand...

Hope that helps!

Also, what do you mean by, "make Merb more visible" ?

Chino

P.S.

Come hang out in merb at freenode !

Hey Ed-


	partial(:comments) just renders the _comments.herb partial template.  
The js method calls .to_json on that partial content to properly  
escape the text for the browser so it doesn''t choke on unescaped  
html. .jerb templates set the content type to javascript so that the  
browser executes it. Similar to rjs except .jerb you just write your  
javascript yourself and then use erb tags to make parts of the js  
dynamic.

	Merb is fun, I''m glad you like it. I do plan on making a merb wiki  
or site soon. I am just super busy so I am not sure when I will get  
the time. Also Ed I think you were the one asking about ActiveRecord  
sessions and reading the rails sessions in merb. Last night I  
commited this functionality. I made an ActiveRecord sessions store  
that can use the same sessions table as your rails app. You can also  
pass the session_id in the query styring when you redirect to merb  
from rails. Merb will pick up the sessions_id from the query string  
and find the proper sessions from the rails sessions table. You can  
modify and save the sessions and rails will pick up those changes ion  
its side as well.

	To use this you just need to make sure you have a sessions table 
(look at the sample app for a migration to create one) and then you  
must set a config option in your dist/conf/merb.yml

---
:host: 0.0.0.0
:port: "4000"
:allow_reloading: true
:sql_session: true

^^ the sql_session is set to true and then merb will take care of  
setting up the AR sessions.

Ahh, very helpful info.

That''s super news Ezra! Thanks for implementing that option - it
really helps what I''m doing with Merb.

Thanks again,

Ed
