Low code and no code development are handy for developing a website without a technical background. Liferay came with the Object concept, which is able to generate the persistence and service layers by just defining the required fields from the Liferay control panel. In this blog, here are some essential points from the objects.
- 1. Notification for an object entry
- 2. Mappings between objects
- 3. Working with Liferay Object Actions
- 4. Liferay Objects With Collections
Mapping between object definitions
With Liferay Objects we can map two or multiple Objects together, Right now we will map Invoice and Loan object, One Invoice can have a multiple Loans.
Add Object 1 : Invoice
- Navigate to the Control panel > OBJECT > Objects.
- Click on Add Object.
- Give Label, Plural Label, and Object Name
- Click on save button
- Now navigate to the new Object and go to the Field section.
- Add required fields
Add Object 2 : Loan
- Create one more object for Loan
- Now navigate to the Loan Object and go to the Field section.
- Add required fields
Its Time To Map The Objects
As we want to map one Invoice with multiple Loans Mapping will be added in Invoice Object
- Navigate to the Invoice Object
- Now navigate to the Relationship Tab
- Click on Add Relationship button
- Enter details and save it
Great!! Now publish both objects and that's it.
