How to check if model already exists in get it before registering?

Question

I have been using get_it package a lot lately and it has been pretty useful. However sometimes i need to check if a model has been registered before as a singleton before registering. Otherwise i will get an exception saying this model is already registered. Is there anyway to do so?

Solution

First of all, you don't need to check this logic. Because if the structure is a singleton, you have to register when the application runs. However, they thought to test this feature, you can try the isRegistered function. You can view the readme file.
