### `regex_match(value: Any, regex: str) -> bool`
|
|
|
|
Check if `value` matches Regular Expression `regex`.
|
|
|
|
Example:
|
|
|
|
```python
|
|
return regex_match(request.user.username, '.*admin.*')
|
|
```
|
|
|
|
### `regex_replace(value: Any, regex: str, repl: str) -> str`
|
|
|
|
Replace anything matching `regex` within `value` with `repl` and return it.
|
|
|
|
Example:
|
|
|
|
```python
|
|
user_email_local = regex_replace(request.user.email, '(.+)@.+', '')
|
|
```
|
|
|
|
### `list_flatten(value: list[Any] | Any) -> Optional[Any]`
|
|
|
|
Flatten a list by either returning its first element, None if the list is empty, or the passed in object if its not a list.
|
|
|
|
Example:
|
|
|
|
```python
|
|
user = list_flatten(["foo"])
|
|
# user = "foo"
|
|
```
|
|
|
|
### `ak_call_policy(name: str, **kwargs) -> PolicyResult`
|
|
|
|
:::info
|
|
Requires authentik 2021.12
|
|
:::
|
|
|
|
Call another policy with the name _name_. Current request is passed to policy. Key-word arguments
|
|
can be used to modify the request's context.
|
|
|
|
Example:
|
|
|
|
```python
|
|
result = ak_call_policy("test-policy")
|
|
# result is a PolicyResult object, so you can access `.passing` and `.messages`.
|
|
# Starting with authentik 2023.4 you can also access `.raw_result`, which is the raw value returned from the called policy
|
|
# `result.passing` will always be a boolean if the policy is passing or not.
|
|
return result.passing
|
|
|
|
result = ak_call_policy("test-policy-2", foo="bar")
|
|
# Inside the `test-policy-2` you can then use `request.context["foo"]`
|
|
return result.passing
|
|
```
|
|
|
|
### `ak_is_group_member(user: User, **group_filters) -> bool`
|
|
|
|
Check if `user` is member of a group matching `**group_filters`.
|
|
|
|
Example:
|
|
|
|
```python
|
|
return ak_is_group_member(request.user, name="test_group")
|
|
```
|
|
|
|
### `ak_user_by(**filters) -> Optional[User]`
|
|
|
|
Fetch a user matching `**filters`.
|
|
|
|
Returns "None" if no user was found, otherwise returns the [User](/docs/user-group/user) object.
|
|
|
|
Example:
|
|
|
|
```python
|
|
other_user = ak_user_by(username="other_user")
|
|
```
|
|
|
|
### `ak_user_has_authenticator(user: User, device_type: Optional[str] = None) -> bool` (2021.9+)
|
|
|
|
:::info
|
|
Only available in property mappings with authentik 2022.9 and newer
|
|
:::
|
|
|
|
Check if a user has any authenticator devices. Only fully validated devices are counted.
|
|
|
|
Optionally, you can filter a specific device type. The following options are valid:
|
|
|
|
- `totp`
|
|
- `duo`
|
|
- `static`
|
|
- `webauthn`
|
|
|
|
Example:
|
|
|
|
```python
|
|
return ak_user_has_authenticator(request.user)
|
|
```
|
|
|
|
### `ak_create_event(action: str, **kwargs) -> None`
|
|
|
|
:::info
|
|
Requires authentik 2022.9
|
|
:::
|
|
|
|
Create a new event with the action set to `action`. Any additional key-word parameters will be saved in the event context. Additionally, `context` will be set to the context in which this function is called.
|
|
|
|
Before saving, any data-structure which are not representable in JSON are flattened, and credentials are removed.
|
|
|
|
The event is saved automatically
|
|
|
|
Example:
|
|
|
|
```python
|
|
ak_create_event("my_custom_event", foo=request.user)
|
|
```
|
|
|
|
## Comparing IP Addresses
|
|
|
|
To compare IP Addresses or check if an IP Address is within a given subnet, you can use the functions `ip_address('192.0.2.1')` and `ip_network('192.0.2.0/24')`. With these objects you can do [arithmetic operations](https://docs.python.org/3/library/ipaddress.html#operators).
|
|
|
|
You can also check if an IP Address is within a subnet by writing the following:
|
|
|
|
```python
|
|
ip_address('192.0.2.1') in ip_network('192.0.2.0/24')
|
|
# evaluates to True
|
|
```
|
|
|
|
## DNS resolution and reverse DNS lookups
|
|
|
|
:::note
|
|
Requires authentik 2023.3 or higher
|
|
:::
|
|
|
|
To resolve a hostname to a list of IP addresses, use the functions `resolve_dns(hostname)` and `resolve_dns(hostname, ip_version)`.
|
|
|
|
```python
|
|
resolve_dns("google.com") # return a list of all IPv4 and IPv6 addresses
|
|
resolve_dns("google.com", 4) # return a list of only IP4 addresses
|
|
resolve_dns("google.com", 6) # return a list of only IP6 addresses
|
|
```
|
|
|
|
You can also do reverse DNS lookups.
|
|
|
|
:::note
|
|
Reverse DNS lookups may not return the expected host if the IP address is part of a shared hosting environment.
|
|
See: https://stackoverflow.com/a/19867936
|
|
:::
|
|
|
|
To perform a reverse DNS lookup use `reverse_dns("192.0.2.0")`. If no DNS records are found the original IP address is returned.
|
|
|
|
:::info
|
|
DNS resolving results are cached in memory. The last 32 unique queries are cached for up to 3 minutes.
