falkolab.ext3.direct

falkolab.ext3.direct is a server-side stack for ExtJS 3.

How do I use it?

Let's register api and views:

 >>> from zope.configuration import xmlconfig
 >>> context = xmlconfig.string("""
 ... < configure
 ... xmlns="http://namespaces.zope.org/zope"
 ... xmlns:extdirect="http://namespaces.zope.org/extdirect"
 ... >
 ... < include package="falkolab.ext3.direct" file="meta.zcml" / >
 ...
 ... < extdirect:api
 ... for="zope.app.folder.interfaces.IFolder"
 ... namespace = "my.app"
 ... / >
 ...
 ... < extdirect:view
 ... for="zope.app.folder.interfaces.IFolder"
 ... class="falkolab.ext3.direct.testing.AlbumList"
 ... permission="zope.ManageContent"
 ... name="albumlist"
 ... / >
 ...
 ... < extdirect:view
 ... for="zope.app.folder.interfaces.IFolder"
 ... class="falkolab.ext3.direct.testing.Contact"
 ... permission="zope.ManageContent"
 ... / >
 ...
 ... """)

Direct API:

 >>> print http(r"""
 ... GET /@@directapi HTTP/1.1
 ... Authorization: Basic bWdyOm1ncnB3
 ... """)
 HTTP/1.1 200 Ok
 Cache-Control: no-cache
 Content-Length: ...
 Content-Type: text/javascript;charset=utf-8
 Expires: ...
 Pragma: no-cache
 < BLANKLINE >
 Ext.namespace('my.app');
 my.app.REMOTING_API={"url": "http://localhost/@@directrouter", "namespace": "my.app", "type": "remoting", "actions": {"Contact": [{"name": "getInfo", "len": 1}], "albumlist": [{"formHandler": true, "name": "add", "len": 0}, {"name": "getAll", "len": 0}]}};

Auto add provider :

 >>> print http(r"""
 ... GET /@@directapi?add_provider HTTP/1.1
 ... Authorization: Basic bWdyOm1ncnB3
 ... """)
 HTTP/1.1 200 Ok
 Cache-Control: no-cache
 Content-Length: ...
 Content-Type: text/javascript;charset=utf-8
 Expires: ...
 Pragma: no-cache
 < BLANKLINE >
 Ext.namespace('my.app');
 my.app.REMOTING_API={"url": "http://localhost/@@directrouter", "namespace": "my.app", "type": "remoting", "actions": {"Contact": [{"name": "getInfo", "len": 1}], "albumlist": [{"formHandler": true, "name": "add", "len": 0}, {"name": "getAll", "len": 0}]}};
 Ext.Direct.addProvider(my.app.REMOTING_API);

And Direct Request hanling (for addition see ROUTER.TXT):

 >>> print http(r"""
 ... POST /@@directrouter HTTP/1.1
 ... Authorization: Basic bWdyOm1ncnB3
 ... Content-Length: 71
 ... Content-Type: application/json; charset=UTF-8
 ... Referer: http://localhost/
 ...
 ... {"action":"albumlist","method":"getAll","data":[],"type":"rpc","tid":1}""")
 HTTP/1.1 200 Ok
 Content-Length: 89
 Content-Type: text/javascript
 < BLANKLINE >
 {"action": "albumlist", "tid": 1, "type": "rpc", "method": "getAll", "result": [1, 2, 3]}
