4D for Mobile Tutorial – Using Formatters

A data formatter allows you to map a data type from your database to a specific display on the mobile side. For example, you can define a date, percentage, or currency format. Data formatters can also call some code to create intelligent interfaces.

For example, you can attach a data formatter to phone numbers that open an action menu on the mobile app when the user touches the number (e.g., to call the person or save them in contacts).

You have three formatter types:

4D for Mobile Tutorial – Define filter queries

For a mobile application, data is usually filtered to preserve storage space and provide direct and quick access to essential data.

With 4D, you have two types of filters.

  • A static filter to filter the data for a table. For example, limit to tasks with the status ‘in progress.’
  • A dynamic filter depends on the user’s information. For example, return only the user’s tasks.

 

This tutorial will show you how to use and combine these two filters.

Create your Native Mobile Application with 4D

4D for Android and 4D for iOS allow you to configure, design, build, and deploy native Android and/or iOS apps based on a 4D database. Once generated and deployed, mobile clients can connect to the 4D Server and interact with new or existing data without additional requirements.

4D for Android and 4D for iOS are included in a single integrated 4D component. You can create a mobile project and decide to build it for Android, iOS, or both.

4D handles the complexity and generates an Xcode project in Swift or an Android project in Kotlin. Then, you can reopen them with Xcode and Android Studio and continue to work on them.

This blog post is a compilation of features available in our mobile solution that enables you to build a complete app that goes all out!

Build your Compiled Structure or Component with Build4D

With the introduction of the project mode, it’s pretty easy to manipulate the components of your projects.

In the last few feature releases, we have added several functionalities that allow you to create your own build chain adapted to your team, your working methods, and your needs.

For example:

 

To help you create your own build chain or integrate 4D into a continuous integration tool, we have developed a component named Build4D, available on GitHub with the sources.

For this first step, Build4D allows you to create a compiled structure and a component. We will continue to enrich it to enable you to manage a single-user application, client application, or server application.
