README

Simple graviton client to help importing and exporting data.

Installation

composer require graviton/import-export

Usage

Get help:

./vendor/bin/graviton-import-export help

This will show you all available commands.

Load data to a Graviton instance through REST (using the HTTP interface)

Load from dir:

./vendor/bin/graviton-import-export graviton:import http://localhost:8000 ./test/fixtures

Load data into the core database of a Graviton instance

Besides loading data via the HTTP interface, there are core commands available that allow you to load data into the database backend (MongoDB) of a Graviton instance.

You can import a set of existing files via the graviton:core:import command:

./vendor/bin/graviton-import-export graviton:core:import ./test/data

The core commands file format is slightly different from the normal import format as we need to preserve certain class types. Thus, it's best to insert data into MongoDB and export that into the necessary format. This can be done using the export command:

./vendor/bin/graviton-import-export graviton:core:export ./test/dump-dir

This will dump all the data in the default database. The graviton:core:export has more options, refer to the --help print for more details.

Additionally, we have a purge command that allows you to easily purge (meaning delete!) all collections inside a MongoDB database. You need to pass 'yes' as an only parameter to show that you're sure about that action.

./vendor/bin/graviton-import-export graviton:core:purge yes

File format

The files to be loaded must contain yaml with additional yaml frontmatt (yo dawg...).

The frontmatter part defines what target path a file is to be loaded to.

---
target: /core/app/test
---
{ "id": "test", "name": { "en": "Test" }, "showInMenu": true, "order": 100 }

Importing Files to /file/

• Files cannot be overwritten, an attempt to update a file-dataset with the tool will throw an error.

Example for a File-Upload, i.e. swisscom.png with additional link to be added to the file dataset:

--- 
target: /file/swisscom 
file: swisscom.png 
--- 
id: swisscom 
links: 
    - 
      type: "accountType" 
      $ref: "http://localhost/entity/code/accountType-1" 

Validate Files

Files are not native YML or JSON file so using this command you can easily check if they are ok.

php ./bin/graviton-import-export graviton:validate:import /{full path to}/initialdata/data/

You can also check for any subfolder directly. Output (single error sample):

Validation will be done for: 60047 files 
 60047/60047 [============================] 100%
Finished

With: 1 Errors
/initialdata/data/param/0_general/event/action/error_file.yml: Malformed inline YAML string ("error_file) at line 1 (near "id: "error_file").

Authentication and Headers on "put" import

Some endpoints may require basic auth or some cookie or header to be sent. -a and -c can be used in combination.

-a is for "basic auth", this will do a base 64 encode header. -a{user:passw}
-c is for Customer Header(s), -c{key:value}  just add more if needed, -c is array enabled.
php ./bin/graviton-import-export graviton:import http://... /{full path to}/initialdata/data/ -ajohn:doe -cheader1:value1 -cheader2:value2

Building Docker Runtime

docker build -t graviton/import-export .

Docker Runtime

docker run --rm -ti -v `pwd`:/data graviton/import-export

Building phar package

Run phar build:

composer build

Deploying phar host

cf push <name-of-host>

Or use deploy-scripts to deploy in automated blue/green fashion.

TODO

• implement importer
• implement exporter
• build phar
