Hi!
I would like to create a table via the Table.Meta.model with some columns
that are non-queryset data. I manage to populate those columns manually in
the view (see below), but it's impossible to sort the table with those
columns: Cannot resolve keyword u'name' into field.
What is the proper way to mix queryset and non-queryset data in the same
table?
models.py:
class WMS(models.Model):
alias = models.SlugField(max_length=50)
date_created = models.DateTimeField(auto_now_add=True)
date_updated = models.DateTimeField(auto_now=True)
url = models.URLField()
forms.py:
class WMSListTable(tables.Table):
alias = tables.LinkColumn('editWMS', args=[A('pk')])
name = tables.Column()
type = tables.Column()
version = tables.Column()
valid = tables.BooleanColumn()
class Meta:
model = WMS
fields = ('alias', 'url', 'date_created', 'date_updated')
views.py:
from owslib.wms import WebMapService
def listWMS(request):
wms_list = WMS.objects.all()
for wms in wms_list:
try:
instance = WebMapService(wms.url)
wms.name = instance.identification.title
wms.type = instance.identification.type
wms.version = instance.identification.version
wms.valid = True
except:
wms.valid = False
wms_table = WMSListTable(wms_list)
RequestConfig(request).configure(wms_table)
return render(request,"basqui/manage_layer_wms_list.html",
{'wms_list':wms_table},context_instance=RequestContext(request))
Thanks a lot!
