Doctrine 2.4 lezy loading loads assosiations on load in separate queries - doctrine-orm

I found strange queries in log and detected source:
echo app()->getCountSql(); // 2
$table->findAll();
echo app()->getCountSql(); // 21
$table is an autogenerated repository for page\route class
after loading routes doctrine loading page for each route in separate query.
i checked proxy genereation, i manualy created Proxy__CG__\page\page and Proxy__CG__\page\route objects and it works fine. I tested metadatas and in route assosiation "page" i found fetch = 2 (LEZY).
What can be reason for this?

i've found answer in one of open doctrine bugs http://www.doctrine-project.org/jira/browse/DDC-1390, i hope this can save some one few hours.

WSO2 IS - POST_DELETE_USER error while deleting user from IS

We have installed WSO2AM 2.6.0 with IS as KM (5.7). We deployed AM as an active-active all in one instance and IS as KM active-active too following all the directives written on the Official documentation.
Based on the documentation, we created the following databases with their respectives datasources: regdb (registry), carbondb, userdb (user store), mb-store, apimdb.
The issue that we have now is on IS side. We tried several things to check that everything was working correctly, like create users, check registry acces etc. We created a user called "test", chaged some properties, etc and after that, we proceed to delete the user.
When we deleted the user we get the following popup on the IS console:
Checking the logs we find the following:
Caused by: org.postgresql.util.PSQLException: ERROR: relation "cm_receipt" does not exist
Position: 135
TID: [-1234] [] [2020-05-11 09:00:30,062] ERROR {org.wso2.carbon.user.mgt.ui.UserAdminClient} - Error when handling event : POST_DELETE_USER
org.wso2.carbon.user.mgt.stub.UserAdminUserAdminException: UserAdminUserAdminException
We checked on the database and the user was deleted correctly and IS carbon console is not displaying it any more, so the user was correctly deleted. Checking a little bit more, the Delete user process is trying to access table "cm_receipt" on carbondb, but the table exists on apimdb.
On postgres side, we have this log during the delete:
<2020-05-08 11:49:50.452 -03:172.19.35.21(45740):wso2carbon#carbondb:[12476]:>ERROR: relation "cm_receipt" does not exist at character 135

Have you got any idea why it can be happening? There is some bug related or something?
Thanks!
There could be two reasons for this.
You've forgot to execute the D script which contains the consent management tables. /wso2is-5.7.0/dbscripts/consent/postgresql.sql.
Your wso2is-5.7.0/repository/conf/consent-mgt-config.xml configuration file is referring to the wrong datasource.
Solution
Check what's the datasource that the consent-mgt-config.xml file is referring to. By default it's like this.
<ConsentManager xmlns="http://wso2.org/carbon/consent/management" xmlns:svns="http://org.wso2.securevault/configuration">
<DataSource>
<!-- Include a data source name (jndiConfigName) from the set of data sources defined in master-datasources
.xml -->
<Name>jdbc/WSO2IdentityDB</Name>
</DataSource>
Here, it's the jdbc/WSO2IdentityDB. Then go to your wso2is-5.7.0/repository/conf/datasources/master-datasource.xml file and check the database of that datasource. If the mentioned tables are not created in that database you can execute the above mentioned postgre.sql script in that database. (If you've already created these tables in a different datasource, you might want to change the datasource defined in the consent-mgt-config.xml file.)
P.S. Never use -Dsetup argument for automatic executions of database scripts on the startup. Always manually execute the database scripts against the database.
P.S. The reason for the user deletion success is that this user consent removal process being a POST_USER_DELETION event. A failure in a POST handler won't effect the action itself.

How can I set up Sitecore Commerce Demo Site (Sitecore.Demo.Retail) to exclude configuration errors?

When I set up the sitecore demo retail site (source - https://github.com/Sitecore/Sitecore.Demo.Retail), I encountered with several problems related to Sitecore Commerce configurations and Sitecore Engine Configurations. I will divide this issues:
I got the following error while running the install-commerce-server.ps1 script on step 5 (Commerce Server Configuration)
I got error 'HTTP Error 502.5 - Process Failure' by URL - http://habitat.commerceengine.dev.local:5000/api/$metadata
On 'reatil.dev.local' site I got error 'Could not find property 'shopName' on object of type: Sitecore.Commerce.Engine.Connect.CommerceEngineConfiguration', when I tried to go on any page with products
I encountered with some errors of Sitecore Commerce Applications (Merchandising Manager, Pricing & Promotions) in Sitecore Experience Platform
However, I have resolved this issues and I hope that this info will be useful for set up of Sitecore Demo Retail site (https://github.com/Sitecore/Sitecore.Demo.Retail).
I have repeated instuctions for install of Sitecore.Demo.Retail and fixed related issues:
This issue had discussed in https://github.com/Sitecore/Sitecore.Demo.Retail/issues/81. You need to check file 'Server2012_FeaturesRequired.txt' like it stated in issued-81. Then you must check file csconfig.xml (path for me - 'c:\Projects\Sitecore.Demo.Retail\install'). I had bad SQL connection to MSSQL Server, which was default. Here example of working variant:
By another way you can run Commerce Server Configurator manually by 'CSConfig.exe /f' (path for me - 'c:\Program Files (x86)\Commerce Server 11\'). Then you can load xml-configuration and set and test SQL connection:
This issue appeared on my environment, because i had wrong SQL connections (by default) in Commerce Engine project in Sitecore.Demo.Retail solution. You must to change all connections in the following files Global.json, Habitat.CommerceAuthoring-1.0.0.json, Habitat.CommerceShops-1.0.0.json.
!!!Don't afraid to check appropriate configs in deployed solution
This error is appeared due the wrong tags (storefront) in 'commerceEngineConfiguration' tag. You need to remove this tags in Sitecore.Demo.Retail.config file. Working variant for example in showConfig.aspx:
You should to check connection strings in file Z.Sitecore.Commerce.UX.Shared.config (path for me - c:\websites\habitat.dev.local\Website\App_Config\Include). By default I had 'localhost:5000/...'

Getting started with Alloy and SQLIte

I am very new to Appcelerator, i've got my head around using Alloy to lay the content of my apps out, and have got to grips with using the Firefox extension to create an SQLite database. I'm stuck at putting the two together though. I've tried the Ti.UI.Database.Install but I'm not 100% which JS file to add that coding to, or where to copy the DB file to. I've followed a few threads and tutorials, tried putting the .db file into the resources folder, lib folder etc but keep coming up with errors. If someone could just talk me through the basic steps that would be great.
This is about using a predefined sqlite database in your app, meaning you want to install a db with preloaded records in its tables.
app/assets is a good place for your_database.sql;
then in app/alloy.js
Ti.Database.install('/your_database.sql', 'your_database')
finally configure the adapter attribute in your alloy's models with:
type: "sql",
db_file: "your_database.sql",
db_name: "your_database",
collection_name: "your_table_name"
Anyway, if you do not need to preload a database, you only have to define your models (here, in example, app/models/foobars.js) and configure their adapter with
type: "sql",
collection_name: "foobars"
This way Alloy will take care to create and install the database (including a foobars table) for you.

Elasticsearch self.published?

I am using elasticsearch-rails gem For my site i need to create custom callbacks. https://github.com/elastic/elasticsearch-rails/tree/master/elasticsearch-model#custom-callbacks
But i really confused by one thing. What means if self.published? on this code?
i try to use this for my models
after_commit on: [:update] do
place.__elasticsearch__.update_document if self.published?
end
but for model in console i see self.published? => false but i don`t know what this means
From the document of elasticsearch-rails.
For ActiveRecord-based models, use the after_commit callback to protect your data against inconsistencies caused by transaction rollbacks:
I think it was used to make sure everything is updated successfully into database before we sync to elasticsearch server

Generate Symfony2 fixtures from DB?

Is it possible to generate fixtures from an existing DB in Symfony2/Doctrine? How could I do that?
Example:
I have defined 15 entities and my symfony2 application is working. Now some people are able to browse to the application and by using it it had inserted about 5000 rows until now. Now I want the stuff inserted as fixtures, but I don’t want to do this by hand. How can I generate them from the DB?
There's no direct manner within Doctrine or Symfony2, but writing a code generator for it (either within or outside of sf2) would be trivial. Just pull each property and generate a line of code to set each property, then put it in your fixture loading method. Example:
<?php
$i = 0;
$entities = $em->getRepository('MyApp:Entity')->findAll();
foreach($entities as $entity)
{
$code .= "$entity_{$i} = new MyApp\Entity();\n";
$code .= "$entity_{$i}->setMyProperty('" . addslashes($entity->getMyProperty()); . "'); \n");
$code .= "$manager->persist($entity_{$i}); \n $manager->flush();";
++$i;
}
// store code somewhere with file_put_contents
As I understand your question, you have two databases: the first is already in production and filled with 5000 rows, the second one is a new database you want to use for new test and development. Is that right ?
If it is, I suggest you to create in you test environment two entity manager: the first will be the 'default' one, which will be used in your project (your controllers, etc.). The second one will be used to connect to your production database. You will find here how to deal with multiple entity manager : http://symfony.com/doc/current/cookbook/doctrine/multiple_entity_managers.html
Then, you should create a Fixture class which will have access to your container. There is an "how to" here : http://symfony.com/doc/current/bundles/DoctrineFixturesBundle/index.html#using-the-container-in-the-fixtures.
Using the container, you will have access to both entity manager. And this is the 'magic': you will have to retrieve the object from your production database, and persist them in the second entity manager, which will insert them in your test database.
I point your attention to two points:
If there are relationship between object, you will have to take care to those dependencies: owner side, inversed side, ...
If you have 5000 rows, take care on the memory your script will use. Another solution may be use native sql to retrieve all the rows from your production database and insert them in your test database. Or a SQL script...
I do not have any code to suggest to you, but I hope this idea will help you.
I assume that you want to use fixtures (and not just dump the production or staging database in the development database) because a) your schema changes and the dumps would not work if you update your code or b) you don't want to dump the hole database but only want to extend some custom fixtures. An example I can think of is: you have 206 countries in your staging database and users add cities to those countries; to keep the fixtures small you only have 5 countries in your development database, however you want to add the cities that the user added to those 5 countries in the staging database to the development database
The only solution I can think of is to use the mentioned DoctrineFixturesBundle and multiple entity managers.
First of all you should configure two database connections and two entity managers in your config.yml
doctrine:
dbal:
default_connection: default
connections:
default:
driver: %database_driver%
host: %database_host%
port: %database_port%
dbname: %database_name%
user: %database_user%
password: %database_password%
charset: UTF8
staging:
...
orm:
auto_generate_proxy_classes: %kernel.debug%
default_entity_manager: default
entity_managers:
default:
connection: default
mappings:
AcmeDemoBundle: ~
staging:
connection: staging
mappings:
AcmeDemoBundle: ~
As you can see both entity managers map the AcmeDemoBundle (in this bundle I will put the code to load the fixtures). If the second database is not on your development machine, you could just dump the SQL from the other machine to the development machine. That should be possible since we are talking about 500 rows and not about millions of rows.
What you can do next is to implement a fixture loader that uses the service container to retrieve the second entity manager and use Doctrine to query the data from the second database and save it to your development database (the default entity manager):
<?php
namespace Acme\DemoBundle\DataFixtures\ORM;
use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Acme\DemoBundle\Entity\City;
use Acme\DemoBundle\Entity\Country;
class LoadData implements FixtureInterface, ContainerAwareInterface
{
private $container;
private $stagingManager;
public function setContainer(ContainerInterface $container = null)
{
$this->container = $container;
$this->stagingManager = $this->container->get('doctrine')->getManager('staging');
}
public function load(ObjectManager $manager)
{
$this->loadCountry($manager, 'Austria');
$this->loadCountry($manager, 'Germany');
$this->loadCountry($manager, 'France');
$this->loadCountry($manager, 'Spain');
$this->loadCountry($manager, 'Great Britain');
$manager->flush();
}
protected function loadCountry(ObjectManager $manager, $countryName)
{
$country = new Country($countryName);
$cities = $this->stagingManager->createQueryBuilder()
->select('c')
->from('AcmeDemoBundle:City', 'c')
->leftJoin('c.country', 'co')
->where('co.name = :country')
->setParameter('country', $countryName)
->getQuery()
->getResult();
foreach ($cities as $city) {
$city->setCountry($country);
$manager->persist($city);
}
$manager->persist($country);
}
}
What I did in the loadCountry method was that I load the objects from the staging entity manager, add a reference to the fixture country (the one that already exists in your current fixtures) and persist it using the default entity manager (your development database).

DoctrineFixturesBundle
How to work with Multiple Entity Managers
you could use https://github.com/Webonaute/DoctrineFixturesGeneratorBundle
It add ability to generate fixtures for single entity using commands like
$ php bin/console doctrine:generate:fixture --entity=Blog:BlogPost --ids="12 534 124" --name="bug43" --order="1"
Or you can create full snapshot
php app/console doctrine:generate:fixture --snapshot --overwrite
The Doctrine Fixtures are useful because they allow you to create objects and insert them into the database. This is especially useful when you need to create associations or say, encode a password using one of the password encoders. If you already have the data in a database, you shouldn't really need to bring them out of that format and turn it into PHP code, only to have that PHP code insert the same data back into the database. You could probably just do an SQL dump and then re-insert them into your database again that way.
Using a fixture would make more sense if you were initiating your project but wanted to use user input to create it. If you had in your config file the default user, you could read that and insert the object.
The AliceBundle can help you doing this. Indeed it allows to load fixtures with YAML (or PHP array) files.
For instance you can define your fixtures with:
Nelmio\Entity\Group:
group1:
name: Admins
owner: '#user1->id'
Or with the same structure in a PHP array. It's WAY easier than generating working PHP code.
It also supports references:
Nelmio\Entity\User:
# ...
Nelmio\Entity\Group:
group1:
name: Admins
owner: '#user1'
In the doctrine_fixture cookbook, you can see in the last example how to get the service container in your entity.
With this service container, you can retrieve the doctrine service, then the entity manager. With the entity manager, you will be able to get all the data from your database you need.
Hope this will help you!
