How to use single inheritance in propel schema - propel

I need to make a 'Event' class and propel schema with Columns:
id
employee_id
date_start
date_end
type
How to implement the simple inheritance based on the type column.
All classes should extend the abstract Event class.
Initial sub-class:
JoinEvent
can anyone write a schema for it?
I have written schema but not sure whether it is correct or not.
<table name="event" phpName="Event">
<column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true" />
<column name="employee_id" type="integer" required="true" />
<column name="date_start" type="date" required="true" />
<column name="date_end" type="date" required="false" />
<column name="type" type="integer" inheritance="single">
<inheritance key="1" class="JoinEvent" extends="Event"/>
</column>
<foreign-key foreignTable="employee" name="FI_event_employee">
<reference local="employee_id" foreign="id" />
</foreign-key>
</table>
Please help me.

Propel2 Reverse second run has deleted columns

I am new to propel. There doesn't appear to be a version command built in, but composer shows propel2 in my description.
I reverse engineered my scheme and models from the database then took six months off the project, came back, remastered the database directly, deleted the generated-classes, and the generated-reversed-database.
I then ran
propel reverse "mysql:host=localhost;dbname=MyVanLog;user=**;password=**"
When that completed I opened my schema.xml file and visually verified that the fuel price column no longer exists.
<table name="LogEntries" idMethod="native" phpName="Logentries">
<column name="LogEntryId" phpName="Logentryid" type="INTEGER" primaryKey="true" autoIncrement="true" required="true"/>
<column name="UserId" phpName="Userid" type="INTEGER" primaryKey="true" required="true"/>
<column name="RvId" phpName="Rvid" type="INTEGER" primaryKey="true" required="true"/>
<column name="Title" phpName="Title" type="VARCHAR" size="45" required="true"/>
<column name="Description" phpName="Description" type="CLOB"/>
<column name="Longitude" phpName="Longitude" type="DECIMAL" size="10" scale="8"/>
<column name="Latitude" phpName="Latitude" type="DECIMAL" size="10" scale="8"/>
<column name="Temperature" phpName="Temperature" type="DECIMAL" size="3" scale="1"/>
<column name="Private" phpName="Private" type="VARCHAR" size="1" sqlType="bit(1)" required="true"/>
<column name="CreatedOnUTC" phpName="Createdonutc" type="TIMESTAMP" required="true"/>
<column name="ModifiedOnUTC" phpName="Modifiedonutc" type="TIMESTAMP" required="true"/>
<foreign-key foreignTable="Users" name="FK_36">
<reference local="UserId" foreign="UserId"/>
</foreign-key>
<foreign-key foreignTable="Rvs" name="FK_40">
<reference local="RvId" foreign="RvId"/>
<reference local="UserId" foreign="UserId"/>
</foreign-key>
<index name="fkIdx_36">
<index-column name="UserId"/>
</index>
<index name="fkIdx_40">
<index-column name="RvId"/>
<index-column name="UserId"/>
</index>
<vendor type="mysql">
<parameter name="Engine" value="InnoDB"/>
</vendor>
Then I run propel build to generate my models. I open my base/LogEntries file and it has all the methods to manipulate the field that is no longer there. I won't paste the entire file, but here is the get method.
/**
* Get the [fuelpriceinvalid] column value.
*
* #return string
*/
public function getFuelpriceinvalid()
{
return $this->fuelpriceinvalid;
}
Does anyone know what I missed?
I had an extra schema.xml file hanging out in the project directories that was being read instead of the one I generated causing the old fields to generate. This was likely just a mistake on my part, not a propel bug.

spring-boot with liquibase #OneToMany mapping

I have two entity Person and Address. And Person can have multiple Address.
<createTable tableName="ADDRESS">
<column name="id" type="bigint(20)" autoIncrement="true">
<constraints primaryKey="true" nullable="false" />
... //columns
</column>
</createTable>
<createTable tableName="PERSON">
<column name="id" type="bigint(20)" autoIncrement="true">
<constraints primaryKey="true" nullable="false" />
... //columns
</column>
</createTable>
<addForeignKeyConstraint
constraintName="fk_constraint_worker_phone_number"
referencedTableName="CONTACT_NUMBER" baseColumnNames="ContactNumbers"
baseTableName="WORKER" referencedColumnNames="id" />
I want 3rd table (like hibernate generate in #OneToMany mapping).
How to do this with liquibase-springboot?
If the relation is truly a OnToMany, you don't need a 3rd table. Simply, add PrimaryKeyJoinColumn.
If the address can be reused for many persons, it's a ManyToMany relation.
You can use #ManytoMany and add information about you joined table un #jointable
Well, in case of liquibase we have to create the 3rd table manually and have to apply the necessary constraints.
Create the table which manages the mapping :
<createTable tableName="PERSON_ADDRESS">
<column name="PERSON_ID" type="BIGINT">
<constraints primaryKey="true" nullable="false" />
</column>
<column name="ADDRESS_ID" type="BIGINT">
<constraints primaryKey="true" nullable="false" />
</column>
</createTable>
Apply the constraints:
1) Ensure that Persons id is unique in the mapping table
2) A foreign key relationship between ADDRESS's id and PERSON_ADDRESS's PERSON_ID
3) A foreign key relationship between PERSON's id and PERSON_ADDRESS's ADDRESS_ID
<addUniqueConstraint
columnNames="PERSON_ID" tableName="PERSON_ADDRESS"
constraintName="UK_PHONE_NUMBERS_ID" />
<addForeignKeyConstraint
constraintName="FK_ADDRESS_PERSON_ADDRESS"
referencedTableName="ADDRESS"
baseColumnNames="ADDRESS_ID"
baseTableName="PERSON_ADDRESS" referencedColumnNames="id" />
<addForeignKeyConstraint
constraintName="FK_PERSON_PERSON_ADDRESS"
referencedTableName="PERSON"
baseColumnNames="PERSON_ID"
baseTableName="PERSON_ADDRESS" referencedColumnNames="id" />

Slug regenerating it self

I'm using the sluggable behavior within Propel to work alongside my CMS/Framework.
Weird thing is, if you change something else on the page, other than the slug, the slug will automatically regenerate using what appears to be the values of the parent element, i.e.
from /slug to id-3-parentid-2-keywords-null-templateid-1-publishdate-null-slug-slug-sortablerank-2-createdat-null-updatedat-null-pagei18ns-pagei18n_0-id-3-locale-en_gb-title-tsadf-description-null-content-p-ssadf-p-page-recursion-pagei18n_1-id-3-locale-fr_fr-title-a which is rather odd.
The only solution I've found so far, is to simply call setSlug to a random value and then set the correct value afterwards.
$page->setSlug('x');
$page->setSlug($this->request->post->get('slug'));
and my schema:
<table name="page" phpName="Page">
<!-- Columns -->
<column name="id" type="integer" required="true" primaryKey="true" autoIncrement="true"/>
<column name="parent_id" type="integer" required="false" />
<column name="title" type="varchar" size="255" required="true" />
<column name="description" type="varchar" size="255" required="false" />
<column name="keywords" type="varchar" size="255" required="false" />
<column name="content" type="longvarchar" required="false" />
<column name="template_id" type="integer" required="false" />
<column name="publish_date" type="date" required="false" />
<!-- Behaviors -->
<behavior name="i18n">
<parameter name="i18n_columns" value="title, description, content" />
<parameter name="default_locale" value="en_GB" />
</behavior>
<behavior name="sluggable">
<parameter name="permanent" value="true" />
</behavior>
<behavior name="sortable" />
<behavior name="timestampable" />
<!-- Foreign Keys -->
<foreign-key foreignTable="page_template">
<reference local="template_id" foreign="id"/>
</foreign-key>
<foreign-key foreignTable="page">
<reference local="parent_id" foreign="id"/>
</foreign-key>
</table>
Note: I've tried with and without the permanent param.
Any idea's anyone?

How to configure Doctrine entities to handle compressed blobs in the database?

I'm using Doctrine 2 as an ORM to the database and i'm having an issue with compressed blobs.
I'm storing text in a compressed blob column in the database. How can i specify this in the entity mapping xml config? I'm currently using type="blob" for this column but this isn't returning a string. I could use type="text" but this returns garbage as it's not uncompressing it.
Can i specify somewhere in my entity config that this text need uncompressing on retrieval and compressing on persisting?
Here's my entity configuration:
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping
http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">
<entity name="AccountNote" table="tblAccountNote">
<id name="intAccountNoteId" type="integer">
<generator strategy="AUTO" />
</id>
<field name="intAccountId" type="integer" nullable="false" unique="no" />
<field name="bolHiddenNote" type="boolean" nullable="false" unique="no" />
<field name="binNote" type="blob" nullable="false" unique="no" />
<field name="strHash" type="string" length="32" nullable="true" unique="no" />
<field name="dtmCreated" type="datetime" nullable="false" unique="no" />
<field name="stmTimestamp" type="datetime" nullable="false" unique="no" />
<many-to-one field="objAccount" target-entity="Account" inversed-by="objNotes">
<join-column name="intAccountId" referenced-column-name="intAccountId" />
</many-to-one>
</entity>
</doctrine-mapping>
In the end we decided on handling the compression in the getter and setter and removing it from the schema.

How do I find a list of subclasses for a propel model with concrete inheritance

I'm building a mini-cms for my local charity (yes, I know I could use a floss project, but they want custom coded)
My propel schema currently looks as such:-
<?xml version="1.0" encoding="UTF-8"?>
<database name="sja" defaultIdMethod="native">
<table name="section">
<column name="id" type="INTEGER" primaryKey="true" required="true" autoIncrement="true" />
<column name="title" type="VARCHAR" required="true" />
<column name="slug" type="VARCHAR" required="true" />
</table>
<table name="page">
<column name="id" type="INTEGER" primaryKey="true" required="true" autoIncrement="true" />
<column name="title" type="VARCHAR" required="true" />
<column name="section_id" type="INTEGER" required="true" />
<foreign-key foreignTable="section">
<reference local="section_id" foreign="id" />
</foreign-key>
</table>
<table name="static_page">
<behavior name="concrete_inheritance">
<parameter name="extends" value="page" />
</behavior>
<column name="content" type="LONGVARCHAR" required="true" />
</table>
<table name="home_page">
<behavior name="concrete_inheritance">
<parameter name="extends" value="page" />
</behavior>
<column name="standfirst_title" type="VARCHAR" />
<column name="standfirst_image" type="VARCHAR" />
<column name="standfirst_content" type="VARCHAR" />
</table>
</database>
I want to be able to get a list that would include "home_page" and "static_page" - without having to create this manually whenever I add a new page type.
Is there an easy way to get a list like this, or do I have to write some magic stuff with Reflection Classes, etc?
After a poke in the right direction from #propel on freenode - I've come up with this for a base concept - haven't tested it yet though
function getSubClasses()
{
$map = $this->getDatabaseMap();
$children = array();
foreach ($map->getRelations() AS $relation)
{
$behaviours = $relation->getRightTable()->getBehaviours();
if (issset($behaviours['concrete_inheritance']['extends']) AND $behaviours['concrete_inheritance']['extends'] == $this->getDatabaseMap()->getClassName())
{
$children[] = $relation->getRightTable()->getClassName();
}
}
return $children;
}
