DynamicDiscriminatorMapBundle
DynamicDiscriminatorMapBundle simplifies the use of Doctrine Single Table and Class Table Inheritance mapping strategy in Symfony 5.3
With this bundle you can adds dynamically all classes of a hierarchy to the options of DiscriminatorMap using a config file. This way you can apply the methodology of 'decoupling'
