Sugar ORM

Insanely easy way to work with Android databases.

Official documentation can be found here - Check some examples below. The example application is provided in the example folder in the source.

Features

Sugar ORM was built in contrast to other ORM's to have:

  • A simple, concise, and clean integration process with minimal configuration.
  • Automatic table and column naming through reflection.
  • Support for migrations between different schema versions.
  • Automatic modification of tables when changing fields.
  • Automatic creation of tables during app installation.

Installing

In order to install Sugar:

Add it in your root build.gradle at the end of repositories:

	allprojects {
		repositories {
			...
			maven { url 'https://jitpack.io' }
		}
	}

Step 2. Add the dependency

	dependencies {
	        implementation 'com.github.mohammadaminha:sugar:v1.0'
	}

	Properties properties = new Properties()
	properties.load(new File(rootDir.absolutePath + '/local.properties').newDataInputStream())
	return properties.getProperty(prop, '')
}

project(':sugar').projectDir = new File(getLocalProperty('sugar.dir'))

include this in your local.properties

sugar.dir=/path/to/sugar/library

add sugar project to the dependencies of your main project (build.gradle)

You should also comment this line just comment this line (library/build.gradle): https://github.com/satyan/sugar/blob/master/library%2Fbuild.gradle#L2

===================

After installing, check out how to set up your first database in official documentation. Check examples of 1.0 and master below:

Examples

SugarRecord

public class Book extends SugarRecord {
  
  String isbn;
  String title;
  String edition;

  // Default constructor is necessary for SugarRecord
  public Book() {

  }

  public Book(String isbn, String title, String edition) {
    this.isbn = isbn;
    this.title = title;
    this.edition = edition;
  }
}

or

public class Book { ... }

Save Entity

Book book = new Book("isbn123", "Title here", "2nd edition")
book.save();

or

SugarRecord.save(book); // if using the @Table annotation 

Load Entity

Book book = Book.findById(Book.class, 1);

Update Entity

Book book = Book.findById(Book.class, 1);
book.title = "updated title here"; // modify the values
book.edition = "3rd edition";
book.save(); // updates the previous entry with new values.

Delete Entity

Book book = Book.findById(Book.class, 1);
book.delete();

or

SugarRecord.delete(book); // if using the @Table annotation 

Update Entity based on Unique values

Book book = new Book("isbn123", "Title here", "2nd edition")
book.save();

// Update book with isbn123
Book sameBook = new Book("isbn123", "New Title", "5th edition")
sameBook.update();

book.getId() == sameBook.getId(); // true

or

SugarRecord.update(sameBook); // if using the @Table annotation 

Bulk Insert

List<Book> books = new ArrayList<>();
books.add(new Book("isbn123", "Title here", "2nd edition"))
books.add(new Book("isbn456", "Title here 2", "3nd edition"))
books.add(new Book("isbn789", "Title here 3", "4nd edition"))
SugarRecord.saveInTx(books);

When using ProGuard

# Ensures entities remain un-obfuscated so table and columns are named correctly
-keep class com.yourpackage.yourapp.domainclasspackage.** { *; }
