kandi X-RAY | eventdispatcher Summary
An event dispatcher framework inspired by the [Kivy project] Property instances are monitored and dispatch events when their value changes. The event callback handler name defaults to on_PROPERTY_NAME and is called with two arguments: the dispatcher instance and the value of the property.

Good morning, in our project we have a REST controller looking like this (it's only pseudocode and not the exact case; here I am giving a simple example showing the overall concept):
...ANSWER
Answered 2022-Mar-23 at 11:27How to ensure composite commands including persisting to db and dispatching events are atomic?
"Outbox Pattern": write the events to the database as part of the transaction; worry about publishing the events separately.
See Reliable Messaging without Distributed Transactions, by Udi Dahan
Either everything is persisted and all events are dispatched or nothing is persisted and no events are dispatched.
Because we have physical constraints (ex: a finite speed of light), all or nothing isn't a guarantee that we can make. We can manage weaker claims, like "at most once" or "at least once".
"At least once" is the weaker claim that is actually useful, but it does mean that subscribers have to be able to recognize repeat messages - in other words, you need idempotent message handling.

I tried to run the fixture below on Symfony 5 using the command php bin/console d:f:l

The same code logic is working fine for Post entities when creating them manually through the CRUD. Are fixtures not compatible with subscribers (events) or did i make a mistake?

QUESTION
I'd like to encode a given class of type T: EventData
with Kotlinx Serialization encodeToString
.
This is my code:
...ANSWER
Answered 2021-Dec-08 at 14:39For Json.encodeToString(event)
to work, it needs the type information for T
. But, this type information is lost at runtime due to the way how generics work in Kotlin/Java.
One way to retain the type information would be by making dispatchEvent
an inline function with T
as a reified type parameter.
However, this also raises the question how you want to serialize event
. You could also use polymorphic serialization of EventData
, rather than trying to serialize T
. This will include an additional class discriminator in your serialized output (it necessarily has to for polymorphic serialization/deserialization to work).
If you serialize the concrete type T
, this class discriminator wouldn't be included, which is questionable; how would whoever will deserialize this know what type it is?
In short, I think you need polymorphic serialization.

Install eventdispatcher
You can use eventdispatcher like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
