问题 I'm writing a SPA in Durandal 2.1. So far so good. However, I'm having great difficulties in selecting the right Data Persistence library to communicate with my PHP (Laravel) REST API. The number one library for Durandal is BreezeJS. It is said that it supports API's without oData / ASP.NET Entity framework. I've searched for many days now, but I can't find any decent resource telling me how to use BreezeJS with my basic PHP REST API. The wish-list is as follows: Persist data between views

问题 According to the breeze api, when setDeleted is called, it will remove the entity from all the related entities. This is true, but the behavior is flawed when importing a deleted item using the entity manager's importEntities function. The deleted entity will have it's navigational properties emptied, but other entities that have navigational properties containing the deleted item will keep that item in their nav lists. If setDeleted is called on the entity, even though it is already deleted,

问题 I have a web application with an Angular / Breeze client side calling into a Breeze Web API, which uses an Entity Framework code first model. I have a datacontext (Angular service) responsible for all communications with server. I would like to completely separate the server development from the client side development so developers need not even have .NET installed on their system. I would like the solution to require very little coding in way of creating fakes, because the app is changing

问题 I use getEntityGraph extension and it works fine except in the following scenario: add a new entity don't save it and call setDeleted on the entity call getEntityGraph by passing the entity and a np collection as parameters When makePathSegmentFn is called, it crashes on this line : grps.forEach(function(grp) { vals = vals.concat(grp._entities.filter(function (en) { return en.getProperty(fkName) === keyValue; })); }); en is null so it raises an exception. I've worked around the problem by

问题 I'm a beginner in Breeze and have a problem with the following situation I have the following model. A Person entity, can have multiple Projects assigned. A project can have multiple Tasks. And each Task has a Priority. I would like to get all the Persons which have at least one Project which has at least one Task with a Priority code 'High'. I found I can use the 'any' or 'some' for working with 2nd level children. var p1 = new breeze.Predicate.create('projects', 'some', 'client.code',

问题 is there a way to create a breeze predicate for a property that its type is Edm.Decimal? because the datatype in next expression is always double and I don't find a way to say to breeze that I just need create a predicate for a decimal type and not double type, because in final url request I got '10.53 d ' value instead '10.53 m ' value, then the server answer me with an error. var p = new breeze.Predicate( 'UnitPrice' , '>=', 10.53); Thanks in advance. 回答1: You can always explicitly state

问题 How do I go about sorting a set of entities in a breeze entity? For example if I have an order with many items, how do I sort the items by orderDate? <div databind="ko with: order"> <ol databind="foreach: items"> <li/> </ol> </div> Also, I can't use items.sort() in the data-bind, because I am making the list items sortable. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CDYQFjAA&url=https%3A%2F%2Fgithub.com%2Frniemeyer%2Fknockout-sortable&ei

问题 Please anyone suggest me, it's good idea to use Durandal and JuqueryMobile for mobile based application (Browser). I am planning to develop an application using Durandal, Jquerymobile, MVC4, KnockoutJs, and BreezeJs. Thanks 回答1: I wouldn't recommend using jQuery mobile because it has a lot of overlapping features w/ durandal. Unless you want to just use jQuery mobile for the controls. I asked on the google group forums and ratchet was suggested instead. Not exactly the answer your looking for
