Commit 964b3f2 fixed an issue where dbObject was returning casting helpers for
fields that were not actually DB objects, but had something in $casting config.
However, because dbObject was no longer calling DataObject->castingHelper, this
exposed a bug that the underlying function db($fieldName) was not returning
field specs for the base fields that are created by SS automatically on all
DataObjects (i.e. Created, LastEdited, etc).
This commit fixes the underlying issue that DataObject->db($fieldName) should
return the field specs for *all* DB fields like its documentation says it will,
including those base fields that are automatically created and do not appear in
$db.
Since ViewableData was returning a casting helper for Link, but DataObject was
only using $this->$fieldname to set values on that casting helper, you could
not use <% if Link %> (or <% if $Link %>) in your templates because Link is not
a field, and thus had no value to be set on the casting helper, causing
hasValue to think that there was no value. Since DataObject->dbObject says that
"it only matches fields and not methods", it seems safe to have it call db(..)
to get the field spec, and not call ViewableData->castingHelper at all.
This caused problems when duplicate() was used in the CMS UI
to duplicate a SiteTree object. Since every object of this type
has a ParentID relation, it copied this empty relation into
new "ghost page".
See https://github.com/silverstripe/silverstripe-cms/issues/689
When DataObject::update() is run with relation fields and the relationship
is new the relationship ID was not set on the DataObject. This patch fixes
this. Fixes issue 6195 in open.silverstripe.org.
$forceWrite was being ignored because it was tested in a part of the
code that is reachable if and only if there are changes to the object.
This patch adds an additional test to correct that logic error.
Also, refrain from needlessly checking for changes when $forceWrite is
true.
Fixes#1687
API: CompositeDBField::setValue() may be passed an object as its second argument, in addition to array.
These changes provide a 15% - 20% performance improvement, and as such justify an small API change in the 3.0 branch. It will likely affect anyone who has created their own composite fields, which is fortunately not all that common.
Lazy loading no longer loads fields from the versions table when querying. This could lead to incorrect data being displayed if the data on the object and the version it pointed to did not match.
API methods to allow setting of the context of the query that generated the DataObject on that object (used by the lazy loading mechanism to correctly query the Stage, Live, or Versions tables)
See https://github.com/silverstripe/sapphire/pull/1178 for context.

Before this was only possible for some specific ones, like onBeforeWrite.
This excludes any callbacks with augment*() or update*() naming,
since these are assumed to be on extension only, with a corresponding
base method available on the class itself (e.g. "updateCMSFields()"
vs "getCMSFields()").
This causes a 'Fatal error: Call to a member function hasMethod() on a non-object'.
This can happen when displaying a field in a gridfield on a belongs_to relationship.
In 3.0 there was some confusion about whether DataLists and ArrayLists
were mutable or not. If DataLists were immutable, they'd return the result, and your code
would look like
$list = $list->filter(....);
If DataLists were mutable, they'd operate on themselves, returning nothing, and your code
would look like
$list->filter(....);
This makes all DataLists and ArrayList immutable for all _searching_ operations.
Operations on DataList that modify the underlying SQL data store remain mutating.
- These functions no longer mutate the existing object, and if you do not capture the value
returned by them will have no effect:
ArrayList#reverse
ArrayList#sort
ArrayList#filter
ArrayList#exclude
DataList#dataQuery (use DataList#alterDataQuery to modify dataQuery in a safe manner)
DataList#where
DataList#limit
DataList#sort
DataList#addFilter
DataList#applyFilterContext
DataList#innerJoin
DataList#leftJoin
DataList#find
DataList#byIDs
DataList#reverse
- DataList#setDataQueryParam has been added as syntactic sugar around the most common
cause of accessing the dataQuery directly - setting query parameters
- RelationList#setForeignID has been removed. Always use RelationList#forForeignID
when querying, and overload RelationList#foreignIDList when subclassing.
- Relatedly,the protected variable RelationList->foreignID has been removed, as the ID is
now stored on a query parameter. Use RelationList#getForeignID to read it.
Avoid PHPUnit throwing "test didn't run any assertions"
notices in PHP. If nothing else, it keeps test output
looking less broken by default, making it more likely
that actual errors do get noticed.
In a usual CMS request, DataObject::db() is called potentially
thousands of times, calling Config::get() constantly for the same
uninherited statics, which is slow. This improves performance
by caching those into DataObject::$_cache_db
On sites with lots of modules, and pages with plenty of database
queries, DataObject::custom_database_fields() can be called
thousands of times, and slow down page render times. This fixes
it so the fields are cached by class in a static variable, and
are cleared when reset() is called on the DataObject.
In cases where a getter on a DataObject calls getComponent() or
other relational getter, $this->model won't have been set at
this point, and a fatal error is triggered.
This fixes it so $this->model is set *before* populateDefaults()
in DataObject::__construct() and the getters can operate normally.
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
We know the subclass of a record by its ClassName value, but code changes
might have meant that class no longer exists. We used to just break,
but this patch overrides the apparent value of ClassName to be
one that exists in that situation
When publishing to live, DataObject#forceChange is called, which wasnt correctly loading
in fields that were lazy (unloaded) if those fields were from composite fields
like Money. The end result is that any Money values would be forced to null on
publish to live
Also changes the API of the (internal, protected) loadLazyFields method so that
not passing a class argument just unlazys all lazy fields regardless of source table
In getField we check if the field we are getting is currently lazy (unloaded), and
load it if it is. This was only working for simple fields though - composite
fields like Money werent working
When querying DataObjects by a generic parent class (like SiteTree for instance), fields added via $db
set on child classes wouldnt appear.
This is because Object::__construct wasnt called early enough in DataObject::__construct, so
extensions werent initialised when $db was first accessed
DataObject::__construct()
The database adapter uses smallint instead of the boolean datatype,
which works around the issue instead of converting the value.
MySQLDatabase::enumValuesForField() - Added stripslashes because backslashes are escaped in the type description
DataObject::requireTable() - Added double quotes to column names in automatically generated indexes for many_many relationships
DataObject::write() - Escaped class name for DB query
DataQuery::getFinalisedQuery() - Escaped class names for DB query
MINOR Use injector for creating many many list objects
MINOR Use injector for creating objects from within the DataList
MINOR Use Injector::inst() for creating objects; cannot rely on this->injector being present due to many classes being created with 'new', so use inst() directly
MINOR Remove injector autoset property for now; automatically setting it breaks a few test cases that don't know about it for now, and it's not needed just yet
Unify the usage across the class. Since the intention is to have a
single site-wide cache, calling via DataObject seems to be a better
option - self could theoretically end up calling a redefined field from
a subclass.

This allows DataList::create(SiteTree) as equivalent to Object::create(DataList, SiteTree), without
having to have a create() function on DataList.
Required for E_STRICT compliance, as child classes cant override create() if they change the arguments.
DBField::create() is also renamed to DBField::create_field(), as this does not just call the constructor, which all other cases of create() do.
Conflicts:

This allows DataList::create('SiteTree') as equivalent to Object::create('DataList', 'SiteTree'), without
having to have a create() function on DataList. Required for E_STRICT compliance.
BUGFIX Don't create new version on related VirtualPage records in SiteTree->onAfterWrite() when the write was triggered through writeWithoutVersion(). Use a new $_nextWriteWithoutVersion flag replacing the -1 Version number for this purpose (AIR-97)
API CHANGE: Add DataList::newObject(), which creates a new object on that DataList.
API CHANGE: RequestHandler::handleRequest() now needs to handle a $model argument, if you override it.
API CHANGE: augmentSQL is now passed a DataQuery object from which query parameters can be extracted.
API CHANGE: DataObjectDecorators that manipulate the query can now define augmentDataQueryCreation().
API CHANGE: The container class argument for DataObject::get() is deprecated.
API CHANGE: DataObject::buildSQL() and DataObject::extendedSQL() are deprecated; just use DataObject::get() now.
API CHANGE: DataObject::instance_get() and DataObject::instance_get_one() are deprecated, and can no longer be overloaded.
API CHANGE: DataObject::buildDataObjectSet() is deprecated.
API CHANGE: Cant't call manual manipulation methods on DataList such as insertFirst()
