# Polling
`unicorn:poll` can be added to the root `div` element of a component to have it refresh the component automatically every 2 seconds. The polling is smart enough that it won't poll when the page is inactive.
```python
# polling.py
from django.utils.timezone import now
from django_unicorn.components import UnicornView
class PollingView(UnicornView):
current_time = now()
```
```html
{{ current_time }}
```
A method can also be specified if there is a specific method on the component that should called every time the polling fires. For example, `unicorn:poll="get_updates"` would call the `get_updates` method instead of the built-in `refresh` method.
To define a different refresh time in milliseconds, a modifier can be added as well. `unicorn:poll-1000` would fire the `refresh` method every 1 second, instead of the default 2 seconds.
```html
{{ update }}
```
## Disable poll
Polling can dynamically be disabled by checking a boolean field from the component.
```python
# poll_disable.py
from django.utils.timezone import now
from django_unicorn.components import UnicornView
class PollDisableView(UnicornView):
polling_disabled = False
current_time = now()
def get_date(self):
self.current_time = now()
```
:::{code} html
:force:
current_time: {{ current_time|date:"s" }}
:::
````{note}
The field passed into `unicorn:poll.disable` can be negated with an exclamation point.
```python
# poll_disable_negation.py
from django.utils.timezone import now
from django_unicorn.components import UnicornView
class PollDisableNegationView(UnicornView):
polling_enabled = True
current_time = now()
def get_date(self):
self.current_time = now()
```
:::{code} html
:force:
current_time: {{ current_time|date:"s" }}
:::
````
## PollUpdate
A poll can be dynamically updated by returning a `PollUpdate` object from an action method. The timing and method can be updated, or it can be disabled.
```python
# poll_update.py
from django.utils.timezone import now
from django_unicorn.components import PollUpdate, UnicornView
class PollingUpdateView(UnicornView):
polling_disabled = False
current_time = now()
def get_date(self):
self.current_time = now()
return PollUpdate(timing=2000, disable=False, method="get_date")
```
:::{code} html
:force:
