Rendering potentially 1000s of nodes can exceed the CPU and memory constraints
of a normal PHP process, as well as the rendering capabilities of browsers.
Set a hard maximum for the renderable nodes, deferring to a "show as list" action
in the main CMS tree. For TreeDropdownField, we don't have the list fallback option,
so ask the user to search for the node title instead.
Also makes both the "node_threshold_total" and "node_threshold_leaf" values configurable
Strictly speaking, no longer required since we auto-quote simple
field names in DataQuery now, but since the majority of sorts in core is
already quoted we should stay consistent.
- Renamed $minNodeCount to more accurate $nodeCountThreshold
- The $minNodeCount attribute wasn't properly respected
during actual querying, so SilverStripe would always traverse
the entire tree (and load all objects into memory),
before then marking nodes as "unexpanded", which prevents
them from actually being rendered.
- Fixes nodes on search results to be expanded by default
- Fixes nodes on search results to correctly ajax-expand
This is to fix a bug that caused CheckboxSetFields to throw an error
when trying to call this function when editing a new DataObject. This
occurred when using the advancedworkflow module.
Thanks to simonwelsh for the majority of the work on this fix.
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.
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.
+ has a special meaning in the URLs so overall it's a good idea to
strip them out. Otherwise they would need to appear in their ugly url
encoded form "%2B".

BUG Issue with deleted records not being queried properly.
API DataQuery::expressionForField no longer requires a second parameter. Rather the query object is inferred from the DataQuery itself. This should improve consistency of use of this function.
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.
Session is not initialized by the time we need to use
the setting in DB::connect(). Cookie values get initialized
automatically for each request.
Tightened name format validation to ensure it can only
be used for temporary databases, rather than switching
the browser session to a different production database.
Encrypting token for secure cookie usage.
Added dev/generatesecuretoken to generate this token.
Not storing in YML config directly because of web access issues.
Enables more generic use of the fixture facilities
without dependency on the YAML format, for example
when creating fixtures from Behat step definitions.
Note: The YamlFixture class needs to be created via
Injector::inst()->create('YamlFixture') now,
direct instantiation is no longer supported.
This bug will surface when using the ORM and adding an join to DataList
where a DataObject inherits another DataObject.
If you for example want to restrict the number of pages that only have a
related Staff object:
$list = DataList::create('Page')
->InnerJoin('Staff', '"Staff"."ID" = "Page"."StaffID");
This will create a SQL query where the INNER JOIN is before the
LEFT JOIN of Page and SiteTree in the resulting SQL string. In MySQL
and PostgreSQL this will create an invalid query.
This patch solves the problem by sorting the joins.
