Play 2.x+ Liquibase Migration Module

Runs Liquibase migrations on Play application startup.

Table Of Contents

Adding Liquibase Module to your Play Scala project

Add dependency to your build.sbt:

libraryDependencies += "com.ticketfly" %% "play-liquibase" % "<version>"

Current version is built against Scala 2.10, 2.11 and 2.12 and works with Play 2.4 and higher.

No additional code changes are necessary. It uses Play Dependency Injection to eagerly run migrations on startup.

Dependency Matrix

Play Scala play-liquibase
2.4 - 2.5 2.10 - 2.11 1.6
2.6 2.11 - 2.12 2.2

Configuration

If only one jdbc connection is defined, that is used by default, no additional configuration needed. E.g.

db.default {
    url      = "jdbc:mysql://localhost/myschema"
    driver   = "com.mysql.jdbc.Driver"
}

Otherwise add to application.conf:

liquibase {
    url      = "jdbc:mysql://localhost/myschema?logger=com.mysql.jdbc.log.Slf4JLogger"
    driver   = "com.mysql.jdbc.Driver"
    user     = "ticketfly"
    password = "bar123"
}

If you are using Slick with Play, you can reference Slick config:

liquibase = ${slick.dbs.default.db}

Supported optional liquibase configuration parameters:
changelog, contexts, defaultCatalogName, defaultSchemaName, databaseClass, driverPropertiesFile, propertyProviderClass, liquibaseCatalogName, liquibaseSchemaName, databaseChangeLogTableName, databaseChangeLogLockTableName

To disable liquibase execution set liquibase.enable=false

Note: Required parameters are: url, driver

Using Liquibase

Liquibase Module works with Liquibase 3.6+

Example changelog.xml:

<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
         http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.6.xsd">

    <changeSet id="1" author="dragisak">
        <comment>Create a table</comment>
        <createTable tableName="my_table">
            <column name="id" type="bigint" autoIncrement="true">
                <constraints primaryKey="true" nullable="false"/>
            </column>
            <column name="event_id" type="bigint">
                <constraints nullable="false"/>
            </column>
            <column name="ticket_type" type="varchar(30)">
                <constraints nullable="false"/>
            </column>
            <column name="onsale_date" type="datetime">
                <constraints nullable="false"/>
            </column>
            <column name="offsale_date" type="datetime">
                <constraints nullable="false"/>
            </column>
        </createTable>
    </changeSet>

</databaseChangeLog>

Place your changelog.xml file in the conf/liquibase directory. That will make it a part of Play distribution.

You can override name and path to changelog file by setting liquibase.changelog configuration parameter. Default is conf/liquibase/changelog.xml

For details on using Liquibase, go to: www.liquibase.org

Using include and includeAll tags

Example changelog.xml (if you place your schema changelogs in conf/liquibase/schema directory and trigger in conf/liquibase/triggers directory):

<?xml version="1.0" encoding="UTF-8"?>
<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog
         http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.5.xsd">

    <includeAll path="./schema" relativeToChangelogFile="true"/>
    <include path="./triggers/trigger-1.xml" relativeToChangelogFile="true"/>

</databaseChangeLog>

Using contexts

Liquibase contexts can be used to maintain a different set of change sets for different environments or uses. For example, you may have one set to maintain the production schema and one set to maintain the test schema, along with a small set of test data

Context is an attribute of the change set

<changeSet id="2" author="bob" context="test">
        ...
</changeSet>

To run the "test" context only, add to your liquibase configuration in application.conf

liquibase.contexts = ["test"]

Loading changes from the classpath

If your database access code is in a sub-module or library, you may want to keep your change files in, for example, src/main/resources/liquibase of that library. In this case you can choose to load your files from the classpath by specifying the changelog attribute and prepending 'classpath:' to the path. In the scenario where your master.xml file is located in src/main/resources/liquibase, add to your liquibase configuration

liquibase.changelog = "classpath:liquibase/master.xml"

Disabling Liquibase migrations

To disable running Liquibase on startup, you can set

liquibase.enable = false

You can disable Liquibase from command line with -Dliquibase.enable=false.

For details on configuring Play app, see Play Production Configuration

Testing With In-memory Database

There is a special options in H2 url to tell H2 to keep schema after Liquibase has finished: DB_CLOSE_DELAY=-1

Also, you have to make sure that it does not force table name to uppercase with DATABASE_TO_UPPER=false

Example:

  val appWithMemoryDatabase = FakeApplication(
    additionalConfiguration = {
      val driver = "org.h2.Driver"
      val url = s"jdbc:h2:mem:test${Random.nextInt()}:test;DATABASE_TO_UPPER=false;DB_CLOSE_DELAY=-1"
      Map(
        "slick.dbs.default.driver" -> "slick.driver.H2Driver$",
        "slick.dbs.default.db.driver" -> driver,
        "slick.dbs.default.db.url" -> url,
        "slick.dbs.default.db.user" -> "sa",
        "slick.dbs.default.db.password" -> "",
        "liquibase.driver" -> driver,
        "liquibase.url" -> url,
        "liquibase.user" -> "sa",
        "liquibase.password" -> ""
      )
    }
  )

  "save and query" in new WithApplication(appWithMemoryDatabase) {
        ...
        val postRequest = FakeRequest(POST, "/test").withJsonBody(Json.toJson(payload))
        val Some(saveResult) = route(postRequest)
        status(saveResult) must equalTo(OK)
        ...
  }

Logging

To show logs generated by Liquibase, add this to your app's logback.xml:

<logger name="liquibase" level="INFO" />
