I have a jQuery table plugin (that is given data from a python script) that I want to add to my pyramid template, although when I run my instance and view the rendered webpage from the template my widget does not show up. I the only thing I can imagine to do is to use deform to make sure that the jQuery can get the correct resources that are linked in the header of the template. Except I am unsure of how I integrate deform to solve my problem.

Here is my init.py: 

from pyramid.config import Configurator
from sqlalchemy import engine_from_config

from .globals import Session, Base

def main(global_config, **settings):
    """ This function returns a Pyramid WSGI application.
    """
    engine = engine_from_config(settings, 'sqlalchemy.')
    Session.configure(bind=engine)
    Base.metadata.bind = engine
    Base.metadata.reflect()

    config = Configurator(settings=settings)
    config.add_static_view('static', 'static/', cache_max_age=3600)
    #config.add_static_view('static', 'deform:static')
    config.add_route('Building', '/Building')
    config.add_route('home', '/')
    config.scan()
    return config.make_wsgi_app()

Here is my template file 'mytemplate.pt':

    <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" >
<head>
    <link rel="stylesheet" href="../static/pylons.css" type="text/css" media="screen" charset="utf-8" />

</div>
<div id="rightcolumn">

<script type="text/javascript">
$(".table_id").flexigrid({
    url: '',
    dataType: '',
    colModel : [
        {display: 'ID', name : 'id', width : 40, sortable : true, align: 'center'},
        {display: 'Name', name : 'name', width : 180, sortable : true, align: 'left'},
        ],
    searchitems : [
        {display: 'ID', name : 'id'},
        {display: 'Name', name : 'name', isdefault: true}
        ],
    sortname: "id",
    sortorder: "asc",
    usepager: true,
    title: 'Buildings',
    useRp: true,
    rp: 15,
    showTableToggleBtn: true,
    width: 700,
    height: 200
});   
</script>
<table class="table_id">
<div id="datacolumn" tal:replace="structure data" />

</table>



<script type="text/javascript">
   deform.load()
</script>
</div>
</body>
</html>

Here is my view.py:

我看不出 Deform 与您的问题有何关系 - 看起来您只需要修复模板中 JS 文件的路径即可。

<head>
    <link rel="stylesheet" href="/static/pylons.css" type="text/css" media="screen" charset="utf-8" />
    <link rel="stylesheet" href="/static/JQueryPlugins/Flexigrid/css/flexigrid.pack.css" type="text/css" media="screen" charset="utf-8" />

    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
    <script type="text/javascript" charset="utf-8" src="/static/JQueryPlugins/Flexigrid/js/flexigrid.pack.js"></script>

</head>

使用 Firebug 或其他工具检查所有资源是否正确加载
