Doctrine inheritance. Is there an easy way to get all child classes/tables for using them in a select field in symfony forms?

문제
I just started to use symfony 1.4 and Doctrine. (Used 1.0 - 1.2 + Propel a lot before).
I thought to give Doctrine a try, because of the fast and huge Development process in the past.
Thanks to jwage ;-)
Im using Table Inheritance. This is a small portion of my schema.yml:
Articles:
columns:
id:
type: integer(4)
primary: true
notnull: true
autoincrement: true
marken_id:
type: integer(4)
notnull: false
user_id:
type: integer(4)
notnull: false
address_id:
type: integer(4)
notnull: false
...
Vehicles:
inheritance:
extends: Articles
type: concrete
Rennfahrzeuge:
columns:
stvo:
type: boolean
notnull: false
default: false
inheritance:
extends: Vehicles
type: concrete
Tourenwagen:
inheritance:
extends: Rennfahrzeuge
type: column_aggregation
keyField: type
keyValue: 1
...
Sonstige:
inheritance:
extends: Rennfahrzeuge
type: column_aggregation
keyField: type
keyValue: 6
Karts:
inheritance:
extends: Vehicles
type: concrete
TonyKart:
inheritance:
extends: Karts
type: column_aggregation
keyField: type
keyValue: 1
...
Sonstige:
inheritance:
extends: Karts
type: column_aggregation
keyField: type
keyValue: 9
Im now thinking of using a simple way to create a the right form.
The user should have to select fields at the top of the form (like you can see here : http://msm-esv.dyndns.org/frontend_dev.php/fahrzeuge/insert )
You should choose the "parent class" like Rennfahrzeuge or Karts and so on.
After that the user should choose the child class like Tourenwagen or Sonstige.
Then the page should reload and display the right form.
Is there any function in Doctrine to get the inheritated/child classes for displaying them in the second select field?
(e.g. Rennfahrzeuge has Tourenwagen,..,..., Sonstige and Karts has TonyKart,...,...,Sonstige)
After that i could create dynamically the assigned form class like:
$chooseMode = $request->getParameter('chooseMode').'Form';
$modeFormClass = new $chooseMode();
or i have thought about just setting the right model in the parent form class.
What are your thoughts? I would really appreciate any suggestions and help :-)
Thanks a lot,
Marco

아래 코드를 사용하여 항목 제목이있는 툴팁을 표시하고 있습니다.
$(document).ready(function() {
ExecuteOrDelayUntilScriptLoaded(tooltipDisplay, "sp.js");
});
var itemID = "";
var title = "";
var offset = null;
function tooltipDisplay() {
$("table.ms-listviewtable tr.ms-itmhover").hover(function(e){
var iids = $(this).attr('iid').split(',');
itemID = iids[1];
offset = $(this).offset();
showTooltip();
},
function(){
$("#tblToolTip").remove();
});
}
function showTooltip() {
var clientContext = new SP.ClientContext.get_current();
if (clientContext != undefined && clientContext != null) {
var list = clientContext.get_web().get_lists().getByTitle("MyList");
this.listItem = list.getItemById(itemID);
clientContext.load(this.listItem, 'Title');
clientContext.executeQueryAsync(Function.createDelegate(this, this.Success),
Function.createDelegate(this, this.Failed));
}
}
function Success() {
title = listItem.get_item('Title');
if (title != undefined && title != null && title != "") {
displayTooltip();
}
}
function Failed(sender, args) {
alert('Getting data failed. </br>Message: ' + args.get_message());
}
function displayTooltip() {
var tempHtml = "<table id='tblToolTip'><tr>";
tempHtml += "<td id='tdToolTip' class='toolTipDisplay'>";
tempHtml += "Title : " + title;
tempHtml += "</td></tr></table>";
$("body").append(tempHtml);
var obj = $("#tblToolTip");
obj.css({"position":"absolute", "top":(offset.top + 20) + "px", "left":offset.left + 20}).fadeIn("slow");
}
.
여기에 사용되는 toolTipDisplay
가 툴팁의 배경색을 정의합니다.클래스가 포함 된 CSS 파일은 코드에서 참조해야합니다. 또는 배경색이 인라인으로 선언 된 색상입니다.
다른 팁
If you need to find the subclasses of a Doctrine Record you could use
$yourSuperObject->getTable()->getOption('subclasses')
or
Doctrine::getTable('SuperClass')->getOption('subclasses');
