CakePHP is an MVC based framework and facilitates unlimited flexibility. A model in cake PHP is used for the data source and all the logics that require to gather the data.
Later we use a Model functions to get these formatted data in Controllers and send them to view using the set function.
Here we are going to learn in how many ways we can use a Model or data source in CakePHP applications.
The naming convention followed in CakePHP help us to reduce our effort and to make the development process rapid.
Since Model is used as a logical unit and data source we can use it in any Controller where we need the data, irrespective the name of model and controllers.
A Controller with name “Users” can access the functions written in Model User without any manual initialization. But the question is how to use another Model and its functions in Users Controller?
When we are developing a complex application we usually need to access data from many tables or we can say from many Models in a single controller.
If there is no association then we need to initialize the other Models manually. Once we initialize these models we can use any functions in these models in the Controller. We can use any data source in any controller.
Even we can use the Model in our plugins Model, in the same way, we use in our standard models.
There are different ways to initialize a model in any Controller:
- Initialize at the start of Controller and use it in any action of Controller.
- Initialize in the particular action of Controller.
- Initialize and Using in Another model.
Initialize at the start of Controller and use it in any action of Controller
There are many such situations when we need to use any model continuously in all the functions, then we need to initialize a model that can be used from anywhere.
Here we once initialize the model is available anywhere in a controller to use. We should not use this method when we are using the Model in only a few functions.
This may create overhead to the application when each time a data source is being loaded without reason.
Initialize in a particular action of Controller
When we have limited usage in a controller then it is not a good practice to initialize a model at the start.
We should initialize when we need only.
There may be some particular function that needs to access data from another model.
Initialize and Using in Another model
There are many such situations arrived when you need to use another model functions in your model, then you need to import that model in your model.
When we need additional data apart from association we need to fetch data from a model that is not the current model. CakePHP provides flexibility to use a number of existing model functions in your model.
This facilitates code reusability and improves the maintainability of application and at the same time reduce overhead and development time.
Hope this article will help you in using a model in Cake PHP in different ways.
Happy Learning 🙂
