Schematic

Schematic allows you to synchronize your Craft setup over multiple environments. It does this by exporting information about assets, database (fields, sections, users), locales and plugins to a YAML file that can be imported in other environments.

Installation

This tool can be installed using Composer. Run the following command from the root of your project:

composer require nerds-and-company/schematic

This will add nerds-and-company/schematic as a requirement to your project's composer.json file and install the source-code into the vendor/nerds-and-company/schematic directory. Composer will also create the executable vendor/bin/schematic.

Usage

Basic usage

The most common usage pattern of this tool, to synchronize from a development to a production environment, would be:

Create a Craft project locally
Set up all of the desired plugins, sections, templates, etc.
Run a Schematic export locally
Optionally, if a revision control system is used, commit the schema file to the local repository
Deploy the Craft application to a prodcution environment
Run a Schematic import remotely

Or, to synchronize from a production to a development environment:

Run a Schematic export remotely
Pull the schema file locally
Optionally, if a revision control system is used, commit the schema file to the local repository
Run a Schematic import locally

Exporting

An export can be created by running:

./vendor/bin/schematic export

To skip exporting a specific of data type, exclusions can be specified in the following form:

./vendor/bin/schematic export --exclude=assetSources

Multiple exclusions can also be specified:

./vendor/bin/schematic export --exclude=assetSources --exclude=categoryGroups

Here is a list of all of the data types and their corresponding exclude parameter values:

Data Type	Exlude Parameter
Asset Sources	assetSources
Asset Transforms	assetTransforms
Category Groups	categoryGroups
Element Indexes	elementIndexSettings
Fields	fields
Global Sets	globalSets
Locales	locales
Plugins	plugins
Plugin Data	pluginData
Sections	sections
Tag Groups	tagGroups
Users	users
User Groups	userGroups

When craft is in a different directory than ./craft/app, set the path with an environment variable. For example:

export CRAFT_APP_PATH=./vendor/craft/app; ./bin/schematic export

This will generate a schema file at craft/config/schema.yml. The file path can be changed using the --file flag, for instance schematic export --file=path/to/my-schema.yml

If Craft is not installed yet, Schematic will run the installer for you. Make sure the following environment variables have been set:

CRAFT_USERNAME
CRAFT_EMAIL
CRAFT_PASSWORD
CRAFT_SITENAME
CRAFT_SITEURL
CRAFT_LOCALE

Optional environment variables (similar to the PHP constants):

CRAFT_BASE_PATH
CRAFT_APP_PATH
CRAFT_VENDOR_PATH
CRAFT_FRAMEWORK_PATH
CRAFT_CONFIG_PATH
CRAFT_PLUGINS_PATH
CRAFT_STORAGE_PATH
CRAFT_TEMPLATES_PATH
CRAFT_TRANSLATIONS_PATH
CRAFT_ENVIRONMENT

Importing

To run an import with schematic, a schema file needs to be present. An import can be created by running:

./vendor/bin/schematic import

By default schematic will look at ./craft/config/schema.yml. To change the path where schematic will look for the schema file, use the --file flag.

Optionally the --force flag can be used to make the import delete any items which are not mentioned in the import file.

WARNING!! This will also delete any related content.

To skip importing a specific of data type, exclusions can be specified in the following form:

./vendor/bin/schematic import --exclude=assetSources

Multiple exclusions can also be specified:

./vendor/bin/schematic import --exclude=assetSources --exclude=categoryGroups

Here is a list of all of the data types and their corresponding exclude parameter values:

Data Type	Exlude Parameter
Asset Sources	assetSources
Asset Transforms	assetTransforms
Category Groups	categoryGroups
Element Indexes	elementIndexSettings
Fields	fields
Global Sets	globalSets
Locales	locales
Plugins	plugins
Plugin Data	pluginData
Sections	sections
Tag Groups	tagGroups
Users	users
User Groups	userGroups

Keys in the schema file can be overridden by passing an override file to schematic using the --override_file flag, for instance: vendor/bin/schematic import --override_file=craft/config/override.yml.

Overrides

Specific keys can be overriden by adding a key in craft/config/override.yml and setting the corresponding environment variable. The key name in the override.yml needs to be the same as the key you want to override from schema.yml, including any parent key names. The value has to start and end with a % (percentage sign). The correspending environment value will be SCHEMATIC_{value_without_percentage_signs}.

Example

If the following override.yml is defined:

parent:
    key_name: %key_value%

Then the environment variable SCHEMATIC_KEY_VALUE needs to be set. The value of this environment variable will override the key key_name. If the environment variable is not set Schematic will throw an error.

Hooks

This tool has three hooks that extending code can plug in to. An example of a project using some of these hooks is the Schematic plugin for AmNav.

registerMigrationService

Called by	`NerdsAndCompany\Schematic\Services\Schematic::importFromYaml()`, `NerdsAndCompany\Schematic\Services\Schematic::exportToYaml()`
Return	An array where the keys are a name and the values are a Migration Service.

Gives plugins a chance to register their own Migration Services to Schematic in order to import or exports their own data.

public function registerMigrationService()
{
    return [
		'amnav' => craft()->schematic_amNav
	];
}

registerSchematicSources

Called by	`NerdsAndCompany\Schematic\Services\Sources::getSource()`
Return	An array where the keys are mapped to a value depending on the indexFrom param of the source, id or handle.

Gives plugins a chance to register their own Migration Services to Schematic in order to import or exports their own data.

public function registerSchematicSource($indexFrom)
{
    $mapping = [
        'createSomething:handle1' => 'createSomething:1'
    ];
    return $indexFrom == 'handle' ? $mapping : array_flip($mapping);
}

registerSchematicFieldModels

Called by	`NerdsAndCompany\Schematic\Models\FieldFactory::build()`
Return	An array where the keys are a the name of the fieldtype the mapping is for and the values are the fully qualified name of the custom field model class.

Gives plugins a chance to add custom mappings to Schematic for custom field types.

public function registerSchematicFieldModels()
{
    return [
		'fieldType' => Plugin_CustomSchematicFieldModel
	];
}

A plugin that want to make use of this functionality needs to extend NerdsAndCompany\Schematic\Models\Field, for example

<?php

namespace Craft;

class Plugin_CustomSchematicFieldModel extends \NerdsAndCompany\Schematic\Models\Field
{
    //…
}
