Realm for React-native. reset database

问题

I'am new in realm with react-native.

I change schema often, but get migration error everytime I change.

How do I reset realm database when I change schema?

回答1:

You can just delete the app from the device or the simulator to reset the Realm.

回答2:

It depends, if you are using Genymotion (for ANDROID simulation) you would use a different approach. Please note that for both approaches (XCODE & GENYMOTION) you will be reseting the simulator to factory settings...

Here are the steps I used to do this for Android :

1. Open GenyMotion Manager

2. Select the Virtual Device (e.g. Samung Galaxy S6).

3. If you are on OSX. Press CMD + F (reverts to factory setting)

4. If you are on WINDOWS. Press CTRL + F (reverts to factory setting)

5. You can also do this by RightClick action on the item and selecting (Reset this virtual device to factory state) on your device.

6. Enjoy!

Using Android Emulator Genymotion

In your app

const realm = await getRealm();
console.log(realm.path);

copy the result from console.log () which will be the path of your .realm file.

In (Cmd or Terminal)

adb shell rm /data/data/com.example.package/files/default.realm
