How to add a Model?
- Model is a logical part of application which communicate with the database entities.Our model is already created which is database entity model or entity framework model now we are just creating a RegistrationViewModel class which contains the initialization of database entities model.View Model (just like a class) is created because when multiple entities are used in a single view then we bind the view with view model.For example in patient registration page/form we want to display the patient list also then we need two things, one is patient object initialization and other is patient list.So these two patient and patient list objects are initialized in the view model and we tightly bind the view with view model.First create a model class or (view model class) by right clicking on the model folder and go to Add > Class.
- Pop-up window will appear, just select the Class and the enter the name of class RgistrationViewModel.cs and click Add button.
- Your RegistrationViewModel class is created.e.g
- Now initialize the patient entity model from the entity framework model namespace or [HIMS.Model].So we are first adding a reference of HIMS.Model project to HIMS.Patient.Registration project.
- Pop-up window will appear and under Projects > Solution check HIMS.Model project and click OK.
- HIMS.Model project reference is added to your project.Now include the namespace of HIMS.Model (using HIMS.Model) to RegistrationViewModel class and initialize the patient object by get and set property.
- In the next post we will make a patient registration form tightly bound with the RegistrationViewModel using razor engine. If you have any query the regarding the asp.net mvc, please feel free and post a comment right blow. Thank you
