Clearing Magento after testing

Question

I am currently doing a lot of tests in Magento so I can get familiar with it. Unfortunately the database is extremely cluttered with my tests. I wish to clear up the database so I can start over again. This means doing the following:

• Clearing all products
• Clearing all attributes
• Clearing all attribute sets
• Clearing all categories
• Clearing all orders, shipments, transactions etc.

I have found a post on the Magento forums for clearing the products, which is the following SQL:

SET FOREIGN_KEY_CHECKS = 0;

INSERT  INTO `cataloginventory_stock`(`stock_id`,`stock_name`) VALUES (1,'Default');
TRUNCATE TABLE `catalog_product_entity`;
SET FOREIGN_KEY_CHECKS = 1;

I would need the same for the others mentioned. Unfortunately I don't know which tables are holding all the different data, otherwise I would've done it by myself. I also don't want to clear the wrong tables by accident. I hope you can help me!

You can use this function to delete attribute sets.

 $resource = Mage::getSingleton('core/resource');
$db_read = $resource->getConnection('core_read');
 
$attribute_sets = $db_read->fetchCol("SELECT attribute_set_id FROM " . $resource->getTableName("eav_attribute_set") . " WHERE attribute_set_id<> 4 AND entity_type_id=4");
foreach ($attribute_sets as $attribute_set_id) {
    try {
        Mage::getModel("eav/entity_attribute_set")->load($attribute_set_id)->delete();
    } catch (Exception $e) {
        echo $e->getMessage() . "\n";
    }
}

And look for this table to remove attribute

catalog_eav_attribute
eav_attribute
eav_attribute_set

Check eav_attribute column is_user_defined so you can get some idea.

For Magento 2, see this Gist.

Answer 2

You can just empty the whole database and Magento will run all its install/upgrade/data scripts again on the next pageload. This will "factory reset" Magento and will destroy all your changes.

A good habit is to create a module that contains all your basic store settings inside install/upgrade/data scripts. This has the benefit that these settings are stored in version control and all the different websites you have for the store (production, staging, user acceptance testing, etc.) will be kept up to date.

If there are multiple persons working on a site, we even create a new module for every setting group so the versions don't conflict when we merge code.

In your case, I would create a module that setups all the settings you want to keep. If you wipe the database, Magento will be completely clean AND including the settings you want!

You can have a look at the install/upgrade scripts of core Magento to see how Magento installs it's initial data/settings.

Answer 3

Prior to launching a new Magento eCommerce website, at development phase, you’ll always have to carry out testing and this will require creating test orders and customers to ensure that all processes function correctly and as you would expect.

This can often end up leaving a load of test data in the system which you won’t be wanting once the site is launched. Magento is notorious for inserting data in multiple database tables so we’ve provided the SQL script below that will cleanly delete all this data from your Magento database (and reset the increment counters for sales, invoices, customers and shipping). This has been tested and confirmed working on Magento versions from 1.4.0.1 to 1.9.0.1.

#Tested on Magento CE 1.4.1.1 - 1.9.0.1

Answer 4

If you don't need anything at all - just empty the whole DB and do a clean re-install.

Running mass-truncates always worry me with any potential lasting effects of broken key relationships.

Fast DB purging

Using this script,

cd /path/to/my/magento/store
wget -O mage-dbpurge.sh sys.sonassi.com/mage-dbpurge.sh
chmod +x mage-dbpurge.sh
./mage-dbpurge.sh

Are you 100% sure you want to purge $DBNAME? [y/N]: y
Are you 110% sure you want to purge $DBNAME? [y/N]: y

MYSQL DB PURGE COMPLETE

That will completely empty and remove every single table in the database. Do not use it if you need to retain anything.

Answer 5

If you're working with EE you should also truncate the enterprise url rewrite tables, as they don't have foreign key constraints and on importing data (but not explicitly setting urls) the urls of the old products will be connected to your new imported products.

SET FOREIGN_KEY_CHECKS = 0;
TRUNCATE TABLE `catalog_product_entity_url_key`;
TRUNCATE TABLE `catalog_category_entity_url_key`;
TRUNCATE TABLE `enterprise_url_rewrite`;
TRUNCATE TABLE `enterprise_url_rewrite_product_cl`;
TRUNCATE TABLE `enterprise_url_rewrite_category_cl`;
TRUNCATE TABLE `enterprise_catalog_category_rewrite`;
SET FOREIGN_KEY_CHECKS = 1;

Answer 6

One thing no one has mentioned is clearing tax tables. If you don't, you'll get repeat order Id entries in the tax table (when you place orders again at the starting Order Id, you'll have the same Id showing up multiple times). The multiple items will show up on invoices/memos as multiple line items, on both the admin and client side. After testing / clearing using the methods in the above posts (and not clearing the tax tables), after a while I had 10 different tax line items showing up for a single order.

Note - tax was/is still charged correctly, but on memos and invoices it was showing all of the items. Very confusing if a client was to see that.

So to add to the above:

TRUNCATE `sales_order_tax`;
TRUNCATE `sales_order_tax_item`;
ALTER TABLE `sales_order_tax` AUTO_INCREMENT=1;
ALTER TABLE `sales_order_tax_item` AUTO_INCREMENT=1; 

And for good measure:

TRUNCATE `sales_payment_transaction`;
ALTER TABLE `sales_payment_transaction` AUTO_INCREMENT=1; 

Answer 7

You should have separate db for tests. See magento test framework. All ideas to clear db after tests are wrong.

Answer 8

I setup a repository for maintaining simple SQL scripts to run before launching a new Magento site. So far they can help:

1. empty test data from Mage; orders, customers, reports, logs etc.
2. empty test data from various extensions
3. set desired IDs for next order, invoice, shipment and creditmemos

https://github.com/ccondrup/mage-reset
Help improve them!

Answer 9

Just my 2 cents...

Rather than figuring out what to delete, and only realising what I have missed later, I run a few VMs, and I use snapshots at various stages, plus I have two separate sites - one live and one test.

It's easy then to have a script to "restore" test from live when I need it. Also, if the customer has access to the test system, they can play with it too before doing anything with live - no need to restore from a backup and losing orders and other changes in the process (though it does test your backup strategy...)

I think this a much better and "safer" process than running a custom (outdated?) script to delete (too much?) stuff...

(Also, feel free to downvote this as I can't comment yet!)

Answer 10

MYSQL Drop and create the DB then add the user privileges and magento admin user.

DROP DATABASE <dbname>;
CREATE DATABASE <dbname>;
GRANT ALL PRIVILEGES ON <dbname>.* TO <dbusr>@localhost IDENTIFIED BY '<dbusr_pass>';
FLUSH PRIVILEGES;

Add Magento admin user:

USE DB_NAME;
LOCK TABLES `admin_role` WRITE , `admin_user` WRITE;
SET @SALT = "rp";
SET @PASS = CONCAT(MD5(CONCAT( @SALT , "ADMIN_PASSWORD") ), CONCAT(":", @SALT ));
SELECT @EXTRA := MAX(extra) FROM admin_user WHERE extra IS NOT NULL;
INSERT INTO `admin_user` (firstname,lastname,email,username,password,created,lognum,reload_acl_flag,is_active,extra,rp_token_created_at) VALUES ('Firstname','Lastname','[email protected]','USER_NAME',@PASS,NOW(),0,0,1,@EXTRA,NOW());
INSERT INTO `admin_role` (parent_id,tree_level,sort_order,role_type,user_id,role_name) VALUES (1,2,0,'U',(SELECT user_id FROM admin_user WHERE username = 'USER_NAME'),'Firstname');
UNLOCK TABLES;

Answer 13

This is a late answer, but it could be helpful.

I'm developing an e-commerce website based on Magento 1.7 and I tend to TDD.

I think we should not bother by cleaning up database manually while we can use Magento beginTransaction and rollback methods.

Here is an example

public function setUp()
{
    parent::setUp();
    /** @var Mage_Core_Model_Resource $core */
    $core = Mage::getSingleton('core/resource');
    $core->getConnection('default_write')->beginTransaction();
}

public function tearDown()
{
    parent::tearDown();
    /** @var Mage_Core_Model_Resource $core */
    $core = Mage::getSingleton('core/resource');
    $core->getConnection('default_write')->rollBack();
    Mage::reset();
}
