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.
We need contributors to help maintain this project, ask @satyan for repo permission
Otherwise you can use another ORM, like https://github.com/requery/requery or https://realm.io/
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.
There are four ways to install Sugar:
This is the preferred way. Simply add:
compile 'com.github.satyan:sugar:1.5'to your project dependencies and run gradle build or gradle assemble.
Declare the dependency in Maven:
<dependency>
<groupId>com.github.satyan</groupId>
<artifactId>sugar</artifactId>
<version>1.5</version>
</dependency>Download the source code and import it as a library project in Eclipse. The project is available in the folder library. For more information on how to do this, read here.
Visit the releases page to download jars directly. You can drop them into your libs folder and configure the Java build path to include the library. See this tutorial for an excellent guide on how to do this.
First, download sugar repository
git clone [email protected]:satyan/sugar.git
include this in your settings.gradle
include ':app' // your module app
include ':sugar'
def getLocalProperty(prop) {
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)
dependencies {
compile project(':sugar')
}You should also comment this line just comment this line (library/build.gradle): https://github.com/satyan/sugar/blob/master/library%2Fbuild.gradle#L2
// apply from: '../maven_push.gradle'===================
After installing, check out how to set up your first database and models here Outdated. Check examples of 1.4 and master below:
public class Book extends SugarRecord {
@Unique
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
@Table
public class Book { ... }Book book = new Book("isbn123", "Title here", "2nd edition")
book.save();or
SugarRecord.save(book); // if using the @Table annotation Book book = Book.findById(Book.class, 1);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.Book book = Book.findById(Book.class, 1);
book.delete();or
SugarRecord.delete(book); // if using the @Table annotation 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(); // trueor
SugarRecord.update(sameBook); // if using the @Table annotation 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);# Ensures entities remain un-obfuscated so table and columns are named correctly
-keep class com.yourpackage.yourapp.domainclasspackage.** { *; }Instant-Run seems to prevent Sugar ORM from finding the "table" classes, therefore it cannot create the DB tables if you run the app for the first time
When running your app for the first time Turn off Instant run once to allow for the DB tables to be created You can enable it after the tables have been created.
To disable Instant-Run in Android Studio:
(Preferences (Mac) or Settings (PC) -> Build, Execution, Deployment -> Instant Run -> Untick "Enable Instant Run..." )
