tw.jqgrid documentation
=======================


tw.jqmultiselect is a tosca widget wrapper around jquery grid plugin
which can be found here :

`http://www.trirand.com/blog/`_

the version released with this package is 3.7.2

in the view controller ::

from tw.jqgrid import JqGrid
colNames = ['ID','Title', 'Synopsis']
colModel = [
{'name':'id', 'index':'id', 'width':20, 'align':'right'},
{'name':'title', 'index':'title','width':100, 'align':'left'},
{'name':'synopsis', 'index':'synopsis','width':580, 'align':'left', 'sortable':False},
]
search_options = {
"caption": "Search...",
"Find": "Find",
"Reset": "Reset",
"sopt" : ['cn', 'bw'],
"closeOnEscape":True,
}

navbuttons_options = {
"view":False,
"edit": False,
"add": False,
"del": False,
"search":True,
"refresh":True,
}

grid_local = JqGrid(id='movie_list', url='fetch', caption='Movies',
colNames=colNames, colModel=colModel,
rowList=[5,10], rowNum=5,
sortname='title',
viewrecords=True,
autowidth=True,
shrinkToFit=True,
search_options = search_options,
navbuttons_options = navbuttons_options,
)


class MoviesController(BaseRestController):

@expose('project.templates.movies.get_all')
def get_all(self):
pylons.c.grid = grid_local
return dict(page='all movies')

in the template::

${tmpl_context.grid()}

now to feed data we need a controller::

@expose('json')
def fetch(self, page=1, rows=10, sidx=1, sord='asc', _search='false',\
searchOper=u'', searchField=u'', searchString=u'', **kwargs):
offset = (int(page)-1) * int(rows)
q = Movie.query
search_bool = eval(_search.capitalize())
if (search_bool):
field = str(searchField)
field_attr = Movie.__getattribute__(Movie, field)
if searchOper == u'cn':
q = medias_q.filter(field_attr.like(u'%%%s%%' % searchString))
if searchOper == u'bw':
q = q.filter(field_attr.like(u'%s%%' % searchString))

result_count = medias_q.count()
total = 1 + result_count / int(rows)
column = getattr(Movie.table.c, sidx)
movies = q.order_by(getattr(column,sord)()).offset(offset).limit(rows)
rows = [{'id' : movie.id,
'cell': [movie.id, '<a href="/medias/%s/">%s</a>' % (movie.id, movie.title),
movie.synopsis]} for movie in movies]
return dict(page=page, total=total, records=result_count, rows=rows)

.. note:: this is written for an elixir model, adapt to your need

design it:

tw.jqgrid rely on tw.uitheme for its design, the smooth theme is the default
you can use any other theme, or roll your own `http://jqueryui.com/themeroller/`_

below a code snippet on how to do that::

from tw.uitheme import lefrog_css, peppergrinder_css
from tw.jqgrid import jqgrid_css, jqgrid_search_css

class CustomGrid(JqGrid):
css = [peppergrinder_css, jqgrid_css, jqgrid_search_css]

grid_local = CustomGrid(.....
