I have a model where I have a two entities, a "Parent" and a "Child". The relationship should be obvious but goes: Parent has zero or more Child entities. The Parent has a navigation property called "Children" with a collection of Child entities. The Child does NOT have a navigation property back to the parent. It only has a foreign key leading back to the parent. When I load these models into my EntityManager, the "Children" navigation property collection is only ever populated with 1 child, even though the given Parent entity in fact have several. I have tried adding a "Parent" navigation

How to force breeze to load the real Node data instead of something like Object {$ref: "5"} ? This happens all the time except for one of my extended properties that I created in my Client side code. The raw JSON has this part: CurrentUserAssignments: [ { $ref: "5" } ], which never gets referred to the node 5, which is also included in raw JSON results. Here is part of my EF Entity: public class Task { public Guid Id {get; set;} private ICollection<Assignment> _assignments; public virtual ICollection<Assignment> Assignments { get { return _assignments ?? (_assignments = new Collection

I am using Entity Framework and Breeze. For an Entity, there is a bit of associated data I would like to provide with the entity. Getting this data is most efficiently done by querying the Entity table and joining to other tables; this query includes a group by sub-query. I am attempting to tack this extra data on by adding it as a [NotMapped] field to the entity: [NotMapped] public string NotMappedField { get; set; } So then I basically want to replace this webapi controller method [HttpGet] public IQueryable<MyObject> MyObjects() { return _contextProvider.Context.MyObjects; } With something

Let's say I have a list of Product entities. Then I want to edit one of these products, so I'm going to call getEntityByKey to get it from the cache. However on the edit screen, it is likely that I'm going to display more properties than in the grid, and in my case I actually need to do an expand() on some of the Product properties. So how do I handle that regarding caching ? If I use getEntityByKey, it's not going to do the expand(). I could execute a query, but then I don't take advantage of cached entities (in case I had already edited the Product before). What strategy should I opt for in

A friend asks "Do you have examples or docs on how to inspect the Breeze change-set data on the server and perform server side validation and security checks before committing the data to the database?" My answer follows. See the " Custom EFContextProvider " topic in the documentation which describes the Breeze.NET facilities for this purpose. Although this topic targets the EFContextProvider<T> specifically, most of the points apply to the base class, ContextProvider<T> , which is helpful when saving to any kind of data store (see the "NoDb" sample for example). The app produced by the

I am trying to use the "any" operator in Breeze to query a many table and I am getting the following error - TypeError: Unable to get value of the property 'isAnonymous': object is null or undefined The only stackoverflow question I can find that seems related is this one, but there is no solution to the isAnonymous issue because the poster did not provide more code: breeze projection : error selecting non scalar navigation properties I am using Breeze 1.4.11 with Entity Framework 5 The query I am trying to run is var getEntities = function (entitiesObservable) { var whereClause = "";
