What does your newvalue.load view look like? Does it display the temp and
timet lists?
Note, your index.html view is incorrect -- it has {{=temp}} and {{=timet}},
but the dictionary returned by the index() function instead uses VA and VB
as keys, so the view should have {{=VA}} and {{=VB}} (should be the same in
your newvalue.load view). Actually, because the returned values are Python
lists, you probably want a more sophisticated display than simply {{=VA}}.
Also, note that there is no reason to have two identical functions. You can
instead have a single function and just use two different views and
extensions (i.e., index.html and index.load).
Even better, just use an Ajax component to load the data and set it to
refresh periodically:
def index():
return dict()
def get_data():
...
return dict(VA=temp, VB=timet)
In views/default/index.html:
{{=LOAD('default', 'get_data.load', ajax=True, timeout=1000, times=
'infinity')}}
In views/default/get_data.load:
{{=VA}}
{{=VB}}
Keep in mind that this is an inefficient way to get realtime updates.
First, you are polling every second, whether or not the data have changed.
Second, you are sending all the data on every request instead of just the
changes. This may be fine for your use case, but a more efficient approach
would be to use a server push pubsub method (e.g., use websockets to
publish updates to the client) -- see
