Configuration
Doctrine controls configuration of features and functionality using attributes. In this section
we will discuss how to set and get attributes as well as an overview of what attributes exist
for you to use to control Doctrine functionality.
Levels of Configuration
Doctrine has a three-level configuration structure. You can set configuration attributes at a
global, connection and table level. If the same attribute is set on both lower level and upper
level, the uppermost attribute will always be used. So for example if a user first sets default
fetchmode in global level to Doctrine_Core::FETCH_BATCH and then sets a table
fetchmode to Doctrine_Core::FETCH_LAZY, the lazy fetching strategy will be used
whenever the records of that table are being fetched.
• Global level - The attributes set in global level will affect every connection and
every table in each connection.
• Connection level - The attributes set in connection level will take effect on each
table in that connection.
• Table level - The attributes set in table level will take effect only on that table.
In the following example we set an attribute at the global level:
Listing
4-1
// bootstrap.php
// ...
$manager->setAttribute(Doctrine_Core::ATTR_VALIDATE,
Doctrine_Core::VALIDATE_ALL);
In the next example above we override the global attribute on given connection:
Listing
4-2
// bootstrap.php
// ...
$conn->setAttribute(Doctrine_Core::ATTR_VALIDATE,
Doctrine_Core::VALIDATE_NONE);
In the last example we override once again the connection level attribute in the table level:
Listing
4-3
// bootstrap.php
// ...
$table = Doctrine_Core::getTable('User');
