SmarterAdminWebView

class smarter.lib.django.views.SmarterAdminWebView(*args, **kwargs)[source]

Bases: SmarterAuthenticatedNeverCachedWebView

An admin-only optimized web view that is never cached.

This class uses the @staff_member_required decorator, applied via Django’s method_decorator to the dispatch method. The @staff_member_required decorator ensures that only users who are marked as staff in Django’s authentication system can access any HTTP method (GET, POST, etc.) on this view. Non-staff users are redirected to the admin login page.

In addition, this view inherits from SmarterAuthenticatedNeverCachedWebView, which itself applies both the @login_required and @never_cache decorators. This means: - Only authenticated staff members can access the view. - Every response is generated fresh for each request, with no caching at any layer.

This combination makes the view ideal for admin pages that display sensitive or frequently changing data, ensuring both strict access control and cache prevention.

Bug Fix:

Fixed a bug where Django method decorators were raising exceptions for unauthenticated users instead of redirecting them to the login page. Replaced the decorators with explicit checks in the dispatch method.

This is used to cache the chat request thread. The key is a combination of: - the class name, - authenticated username, - the chat name, - and the client UID.

Currently used by the ApiV1CliChatConfigApiView and ApiV1CliChatApiView as a means of sharing the session_key.

Parameters:

  • name – A generic object or resource name.

  • uid – UID of the client, assumed to have been created from the machine MAC address and the hostname of the client.

Returns:

A unique cache key string.

Example:

Parameters:

data (Union[dict, str]) – The data to convert, either a dict or a JSON/YAML string.

Returns:

The data as a dictionary.

Return type:

dict

Raises:

SmarterValueError – If the data cannot be converted to a dictionary.

eval_chatbot_url()

If we are a chatbot, based on analysis of the URL format then we need to make a follow up check of the user and account.

Examples

1.) For named urls, we extract the account number from the url,

then we load the account and admin user for that account.

2.) For smarter api urls, we would extract the chatbot id from the url,

then we would load the chatbot, account, and admin user for that account.

3.) For cli api urls, we would extract the chatbot name from the url,

then we would load the chatbot, account, and admin user for that account.

find_session_key()

Returns the unique chat session key value for this request.

The session_key is managed by the /config/ endpoint for the chatbot. The React app calls this endpoint at app initialization to get a JSON dict that includes, among other info, this session_key, which uniquely identifies the device and the individual chatbot session for the device.

For subsequent chat prompt requests, the session_key is intended to be sent in the body of the request as a key-value pair, e.g. {“session_key”: “1234567890”}.

This method will also check the request headers and cookies for the session_key. The session key can be found in one of the following:
