breeze

We are using WebAPI 2.2, with OData v3 and BreezeJS and are having an issue when using inheritance, we have a setup along the following lines (simplified obviously for this issue) We have a Vehicle abstract class and then two other classes (Bus and Car) which inherit from Vehicle, such as: public abstract class Vehicle { public int Id { get; set; } public string Name { get; set; } } public class Bus : Vehicle { public int NumberOfSeats { get; set; } } public class Car : Vehicle { public string Colour { get; set; } } We then have an Activity class which can have a single Vehicle (either a Car

I tried different ways of loading a list of items using breeze and the API Controller, using filters (partly using a custom object and another part using ODataQueryOptions), but none of them turn out to be really successful. Test code in javascript: function test() { EntityQuery .from("Products") /* .withParameters({ filters: [ { column: "Name", value: "12" } ]}) */ .orderBy("Name desc") .skip(30) .take(15) .inlineCount(true) .using(manager) .execute() .then(success) .fail(fail); function success(data) { console.log(data.products); console.log(data.inlineCount); } function fail(error) {

I have a breeze controller that adds an entity during the save changes that the client did not submit. protected override bool BeforeSaveEntity(EntityInfo entityInfo) { if (entityInfo.Entity.GetType() == typeof(User)) { if (entityInfo.EntityState == EntityState.Added) { User user = entityInfo.Entity as User; OrganizationUser orgUser = new OrganizationUser() { Enabled = true, OrganizationId = User.OrgId, User = user }; user.OrganizationUsers.Add(orgUser); } return true; } throw new InvalidOperationException("You can not use this service to modify an entity of type: " + entityInfo.Entity.GetType

Using this: https://genericunitofworkandrepositories.codeplex.com/ and the following set of blog posts: http://blog.longle.net/2013/05/11/genericizing-the-unit-of-work-pattern-repository-pattern-with-entity-framework-in-mvc/ We are trying to use those repositories with Breeze since it handles client side javascript and OData very well. I was wondering how we could use these with Breeze to handle overriding the BeforeSaveEntity correctly. We have quite a bit of business logic that needs to happen during the save (modifying properties like ModifiedBy , ModifiedTime , CreatedBy , etc) but when we

have very simple relationship between two entities and I am trying to expose them with asp.net webapi odata controllers but it seems that something is wrong with $metadata. When I run jaydatasvcutil.exe on the $metadata I get warning: inverseProperty other side missing. When I use breezejs loadNavigationProperty I get similar error. I have the problem even with official example. http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/working-with-entity-relations You can observe the $metadata here http://sdrv.ms/Z5Klfw Please help. When we are generating navigation properties we

I am getting a single entity by using a method fetchEntityByKey , after that I am loading navigation property for the entity by entityAspect.loadNavigationProperty . But loadNavigationProperty always make a call to the server, what I am wondering if I can first check it from cache, if it is exist then get it from there otherwise go the server. How is it possible? Here is my current code return datacontext.getProjectById(projectId) .then(function (data) { vm.project = data; vm.project.entityAspect.loadNavigationProperty('messages'); }); Here is a function that I encapsulated inside datacontext

I work on a project with Entity Framework Code First + Durandal + Breeze. I have these entities models: public class Packing { [Key] public int Id { get; set; } public string PackingDescription { get; set; } ... public virtual List<Isotope> Isotopes { get; set; } public virtual List<PhysicalForm> PhysicalForms { get; set; } public virtual List<ChemicalForm> ChemicalForms { get; set; } } public class Isotope { [Key] public int Id { get; set; } public string Name { get; set; } ... public int PackingId { get; set; } public virtual Packing Packing { get; set; } } public class ChemicalForm { [Key]
