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
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
Added a new DynamicMedia class that wraps umbraco.cms.businesslogic.media.Media which caches GetProperty calls (while DynamicMedia is instantiated)
Added method to DynamicNode to retrieve a property as DynamicMedia: @Model.Media("catPicture"); or @Model.Media("catPicture").umbracoFile;
Added overload to DynamicNode Media method for shorthand if you only want one property; @Model.Media("catPicture","umbracoFile");
@Model.catPicture will still return the nodeId of the media item because we can't easily check the propertyType (no propertyType on IProperty)
var someNode = new umbraco.MacroEngines.DynamicNode(1046) in your template, it instantiates a DynamicNode like you'd expect, but then it doesn't function as a dynamic object
because it wasn't initialised as a dynamic variable [dynamic someNode = new umbraco.MacroEngines.DynamicNode(1046)]
Added a method to DynamicNode called NodeById which returns a new DynamicNode with the ID you pass, so you can call it off @Model
e.g. var item = @Model.NodeById(1046) will still function as a dynamic, even though it was defined as var
Also fixed post-build rule on umbraco.MacroEngines which had an incorrect path for copying umbraco.MacroEngines to presentation (allows debug without manual file copy, I think)
Added AncestorOrSelf overload which doesn't require a Func<DynamicNode,bool> argument
Both changes modify DynamicNode.Parent so that if there is no parent, it returns itself instead of null, (you can't new DynamicNode(null) as it throws exception)
and then in the AncestorOrSelf checks, the loop makes sure that it won't get stuck by continually returning itself (because this.Parent returns this)
