I released Amrita2-1.9.3. Get it from
http://rubyforge.org/projects/amrita2
This release contains Ajax Demo -- Ajax version of Todo tutorial.
Running demo: http://www.brain-tokyo.net:3000/todo/json_list

This is a new feature of Amrita2. Amrita2 now generates a JavaScript
Code as well as Ruby code from HTML template.
So the code can be used by any client-side JavaScript code including
Ajax. I think this is good for making UIs with JavaScript.
Here is a sample
def json_list_script
#path =
File::expand_path("~/amrita2/sample/rails/todoajax/views/todo/json_list.a2html")
#tmpl =Amrita2::JS::TemplateFile.new(path)
tmpl = Amrita2::JS::TemplateText.new <<-END
<div>
Not done:
<div id=''not_done''>
<input id="item_done" name="item[done]"
type="checkbox" value="1" />
<span> </span>
<span id=''description'' />
<span> </span>
<a id=''edit_link''
href="/todo/edit/">Edit</a>
<span> </span>
<a id=''destroy_link''
href="/todo/edit/">Destroy</a>
</div>
Done:
<div id=''done''>
<input checked="checked" id="item_done"
name="item[done]" type="checkbox" value="0" />
<span> </span>
<span id=''description'' />
<span> </span>
<a id=''edit_link''
href="/todo/edit/">Edit</a>
<span> </span>
<a id=''destroy_link''
href="/todo/edit/">Destroy</a>
</div>
<span id=''now'' />
</div>
END
# compiling the template to JavaScript functions
js = Amrita2::JS::CodeGenerator.new
tmpl.js_template(''tmpl'', js)
Amrita2::JS::RUNTIME_SRC + js.results.join("\n")
end
The HTML template is compiled to JavaScript function using DOM
methods. And it will be embeded to another HTML template.
And I have a question.
In this sample, the TEMPLATE is embeded in helper method. But this can
be separated.
In RoR, what directory is best for this template and how should the
view logic get the path of it?
