I am making a waitlist application. I'd like to be able to send applications a unique confirmation code - and later on be able to find a user either by confirmation code or by username.
Will Symfony be able to call Models to say either:
Code->findUser($code_string);
User->getCode();
I believe that the below schema has the relationships, but I'm not sure if this is the Symfony way of tying these relationships together.
Thank you for your time,
user:
id:
last_name: varchar(255)
first_name: varchar(255)
email: varchar(255)
code:
id:
secret: varchar(255)
user_code:
id:
user_id:
code_id:
course:
id:
title: varchar(255)
quarter:
id:
title: varchar(255)
wait_list:
id:
user_id:
course_id:
quarter_id:
Symfony uses Propel by default, and supports Doctrine as a plugin.
Example querying through a many-to-many relationship where table Bugs
is related to table Products
through an intersection table BugsProducts
:
[Bugs] <-- [BugsProducts] --> [Products]
Solution using Propel:
schema.xml
:
<table name="Bugs">
<column name="bug_id" type="INTEGER" required="true"
primaryKey="true" autoIncrement="true" />
</table>
<table name="Products">
<column name="product_id" type="INTEGER" required="true"
primaryKey="true" autoIncrement="true" />
<column name="product_name" type="VARCHAR" size="50" required="true" />
</table>
<table name="BugsProducts">
<column name="bug_id" type="INTEGER" required="true" primaryKey="true" />
<column name="product_id" type="INTEGER" required="true" primaryKey="true" />
<foreign-key foreignTable="Bugs">
<reference local="bug_id" foreign="bug_id" />
</foreign-key>
<foreign-key foreignTable="Products">
<reference local="product_id" foreign="product_id" />
</foreign-key>
</table>
Example query: look up bug #1234, get related products through many-to-many query, and report.
$bug = BugsPeer::retrieveByPK(1234);
$bugProducts = $bug->getBugsproductsJoinProducts();
foreach ($bugProducts as $bp) {
$product = $bp->getProducts();
print "bug id #".$bug->getBugId().": product ".$product->getProductName()."\n"
;
}
Solution using Doctrine:
class Bugs extends Doctrine_Record
{
public function setUp()
{
$this->hasMany('Products', array('local'=>'bug_id',
'foreign'=>'bug_id',
'refClass'=>'BugsProducts'));
}
}
class Products extends Doctrine_Record
{
public function setUp()
{
$this->hasMany('Bugs', array('local'=>'product_id',
'foreign'=>'product_id',
'refClass'=>'BugsProducts'));
}
}
Example query: look up bug #1234, get related products through many-to-many query, and report.
$bugsTable = Doctrine::getTable('Bugs');
$bug = $bugsTable->find(1234);
foreach ($bug->Products as $product) {
print 'Bug #'.$bug->bug_id.': product '.$product->product_name."\n";
