A modeling method and terminal of state machine based on laravel framework

Abstract

The present invention relates to a modeling method and terminal of a state machine based on a Laravel framework, comprising: S1, creating a state machine characteristic, the state machine characteristic includes multiple functions, and using the state machine characteristic in the model of the Laravel framework; S2, in The model state set and migration event set are defined in the model. The model state set configures different state types of the model, and the migration event set configures the state of the model at different stages of the migration event; S3, instantiate the model, and register the migration event set as a model For custom events, the state machine feature will execute the function adapted to it when the model is instantiated and after the model is instantiated; S4. After calling the migration event in the migration event set, the functions in the state machine feature will be executed along with the migration event Different stages execute the functions that adapt to it. With the execution of migration events, different stages will set the state of the model according to the configuration in the migration event set. The invention can quickly create a model with the characteristics of a state machine, and quickly expand the function of the model.

Description

technical field [0001] The invention relates to the field of computer software, in particular to a modeling method and a terminal of a state machine based on a Laravel framework. Background technique [0002] Laravel is an open source PHP web framework created by Taylor Otwell, which aims to implement the MVC architecture of web software. Laravel's features include: support for user authentication and authorization, a modular package system and a dedicated package library, providing It connects many types of relational databases, provides tools to assist in the deployment and maintenance of applications, and develops many syntactic sugars. It is a more popular development framework in the field of PHP application development. [0003] Elocquent in Laravel, an object-relational mapper (ORM) that makes interacting with databases very convenient. When using Elacutent, each database table has a corresponding "model" that is used to interact with that table. In addition to retr...

AI Technical Summary

Problems solved by technology

[0006] Laravel's data model does not support native state machine programming. If it is used to develop relatively complex, multi-state and multi-process business models such as orders and task classes, it usually needs to judge and process business logic in multiple places. , there are often problems such as redundant business code, difficult maintenance and poor readability

In addition, Laravel's model default events only have a few simple data such as post-query events, creating events, post-creating events, updating events, post-updating events, pre-save events, post-save events, pre-delete events, and post-delete events. Operational events cannot effectively and simply register custom events in complex business models, so that the functions of the model cannot be quickly expanded, and the readability of business codes cannot be effectively guaranteed
