Kolumbus allows you to explore your Realm database from within your Android application.

Note: This library is still under heavy development and a lot of improvements has to done. It was made available to collect feedbacks and feature requests.

Installation

In your root build.gradle file, add the Jitpack url to the list of repositories, if you don't have it yet:

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

In your module build.gradle file, add the Kolumbus dependency:

dependencies {
    compile 'com.github.MGaetan89.Kolumbus:kolumbus:v0.9'
}

If you only want to use Kolumbus in your debug build, you can use the following configuration instead:

dependencies {
    debugCompile 'com.github.MGaetan89.Kolumbus:kolumbus:v0.9'
    releaseCompile 'com.github.MGaetan89.Kolumbus:kolumbus-no-op:v0.9'
}

Usage

Check the demo application to see how to use Kolumbus.

The following example assumes that you have two classes named Category and Product in your project, which both inherits from io.realm.RealmModel.

// Kotlin
import io.kolumbus.Kolumbus
import io.kolumbus.KolumbusModule
import io.realm.Realm
import io.realm.RealmConfiguration

// Register the Kolumbus module when defining your Realm configuration
val realmConfiguration = RealmConfiguration.Builder(context)
    .modules(KolumbusModule())
    .build()
Realm.setDefaultConfiguration(realmConfiguration)

// Configure Kolumbus
Kolumbus.explore(Category::class.java)
    .explore(Product::class.java)
    .navigate(context)

// Java
import io.kolumbus.Kolumbus;
import io.kolumbus.KolumbusModule;
import io.realm.Realm;
import io.realm.RealmConfiguration;

// Register the Kolumbus module when defining your Realm configuration
RealmConfiguration realmConfiguration = new RealmConfiguration.Builder(context)
    .modules(new KolumbusModule())
    .build();
Realm.setDefaultConfiguration(realmConfiguration);

// Configure Kolumbus
Kolumbus.build()
    .explore(Category.class)
    .explore(Product.class)
    .navigate(context);

Customization

Override resources

One way to customize the behavior/display of Kolumbus is to override the public resources in your application.

Create a custom Architect

Kolumbus provides a basic way to customize how the content of a table is displayed. To use this feature, you have to extends from Architect and override the desired methods.

// Kotlin
import android.widget.TextView
import io.kolumbus.Architect

class MyArchitect: Architect() {
    override fun displayEmpty(textView: TextView) {
        textView.text = "Field is empty"
    }
}

// Java
import android.widget.TextView;
import io.kolumbus.Architect;

public class MyArchitect extends Architect {
    @Override
    public void displayEmpty(@NonNull TextView textView) {
        textView.setText("Field is empty")
    }
}

Then, you need to pass an instance of your Architect to Kolumbus, as follow:

// Kotlin
import io.kolumbus.Kolumbus

Kolumbus
    // All `explore()` calls you might need
    .withArchitect(MyArchitect())
    .navigate(context)

// Java
import io.kolumbus.Kolumbus;

Kolumbus.build()
    // All `explore()` calls you might need
    .withArchitect(new MyArchitect())
    .navigate(context)

Compatibility

The following table presents the compatibility matrix between Kolumbus versions and Realm versions.

Kolumbus version	Realm version
