Usage is: @foreach(var item in home.ChildItems.OrderBy("catCount, colour desc"))
If you use the simple form of home.ChildItems.OrderBy("catCount") it will use a simpler/faster implementation
Only supports single pass, ascending currently, so no ThenBy implementation or Descending variants
The original query parser supports OrderBy("catCount, name desc") by nesting Expression.Call
Current implementation for DynamicNodeList supports OrderBy("catCount") only
Simplified SQL query used for property type lookup
Added cache clearing for propertyType cache when ContentType.ClearCache is called
Improves performance of new razor property lookups - most improvement on large sets
Caused user-loaded extension methods on DynamicNodeList to be pretty unreliable (would work sometimes, sometimes wouldn't find method - particularly after an iisreset)
Changed this to a return true
Replaced some API calls via Document & Property (database level, not nodefactory) with a single SQL scalar where I was getting the control type (to determine if "0"/"1" should actually be "true"/"false")
Should perform a lot better now
Already had support for YesNoType (where the string value is 1 or 0) being converted/parsed to boolean
Added some TryParse calls to int and decimal respecitvely so that if a IProperty.Value is a valid decimal or int it will be returned from DynamicNode.TryGetMember as such
This enables the .Where operator to have the correct type after property retrieval so that some numerical comparisons will work
Added support for >, >=, <, <= and %[mod] to .Where
@Model.Children.Where("catCount > 1")
@Model.Children.Where("catCount % 2 == 0")
Refactored GenerateEqual into a Factory method HandleDynamicNodeLambdas that takes an ExpressionType
Implemented Expression.NotEqual
@Model.Children.Where("shouldBeVisible != true") => children that are hidden
e.g. @Model.Children.Where("shouldBeVisible == true")
Also changed internal where implementation to handle Func<DynamicNode,bool> as well as Func<DynamicNode,object>
Both left & right side as lambda expressions should work (though I haven't tested this yet)
e.g. @Model.Children.Where("property1 == property2")
Only == (Expression.Equals) is supported currently due to the extra code required to invoke the lambda when generating the final comparison expression
e.g. @Model.Children.Where(node=>node.shouldBeVisible)
To solve this, I used the DynamicQueryable class from the Linq samples which has a parser that can take a string then modified the internals a bit so
that if your object is a DynamicObject, an additional expression tree is generated which calls the TryGetMember on it
The end result is that you can now do this [I have Random(this DynamicNodeList nodes, int max) in my bin folder]
@Model.Children.Where("shouldBeVisible").Random(2) => two nodes, randomly picked, from the ones that should be visible
*Only* Where is implemented here currently, I'll add support by OrderBy and ThenBy after I've tested some more complex scenarios.
I need to fix a small issue with my DynamicLoading of extensions - under some scenarios the class doesn't get found and i'm not sure why.
New DynamicNode .MediaById (because @Model is DynamicNode) to find a media item by id, e.g. if you are using it with @Model.Parameters.imageId
Overloads for MediaById and NodeById that take object and string to match constructors
This makes the code cleaner and also allows for the .Items (underlying initialization data for DynamicNodeList) to be exposed when you have an instance and hide all of the singular properties etc (Url, Name) that are on DynamicNode - they're not applicable for a List.
Rewrote the reflection code for calling methods on DynamicNodeList to allow mix-ins (e.g. external dlls) to have an extension method defined for DynamicNodeList (e.g. Random(nodeCount))
Lambda syntax still doesn't work (e.g. Children.Where(item=>item.shouldBeVisible)) however methods that don't take lamdas (Take, Random[external], Skip, ElementAt, First, etc) work
NiceUrlFetch now uses the new niceUrlJuno function. The result of niceUrlJuno does not include a leading slash. The old NiceUrl (used in the presentation of the URL) does include one, leading to wrong URLs.
Added a cache for the propertyType lookup (within a single DynamicNode instance) in case the razor logic needs to check the same boolean multiple times within a node.
Should improve performance if working with large trees & repeatedly checking a boolean value
