python - Trouble with Tornado and JavaScript Libraries -

-

i'm trying write simple python web application using tornado web server , having trouble using javascript libraries need. wanted use protovis javascript plotting library, added following 'hello world' code snippet template.html:

<script type="text/javascript" src="/protovis-d3.2.js"></script> <script type="text/javascript+protovis"> new pv.panel()     .width(150)     .height(150)     .anchor("center")     .add(pv.label)         .text("hello, world!")         .root.render(); </script>

whenever run webserver, however, , try accessing page, following error @ console:

warning:root:404 /protovis-d3.2.js (127.0.0.1) 0.46ms

the protovis.js file in same directory server.py file, , permissions set correctly. same error when trying src , javascript file know there isn't problem protovis.js file, tornado server's routing.

does know how can src javascript code, thanks.

you should read documentation static files.

in particular, standard way to:

  • create 'static' directory in root of application

  • add following application settings:

    "static_path": os.path.join(os.path.dirname(file), "static")

  • put protovis-d3.2.js in static directory

  • refer file /static/protovis-d2.2.js in html

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
