  1. Which libraries for Java on Github

    Hi,

    I see 3 branches of Breeze support Java on github. What is different?
    The Json-UriBuilder Branches is look fully. I'm intergrating breezejs with java spring and hibernate to use with AngularJS.

    Thanks

      • Northwind example with Java Spring & Hibernate

        Hi,

        I have downloaded java northwind example from github (https://github.com/Breeze/breeze.js.samples/tree/master/java/NorthBreeze)
        Then i create northwind database and deploy server with Java. The server return data and metadata json look good.
        But when i deploy client and call server, i received error:

        "Metadata query failed for: http://localhost:8081/NorthBreeze/breeze/northbreeze/Metadata. Unable to either parse or import metadata: Error configuring an instance of 'NavigationProperty'. The 'foreignKeyNamesOnServer' parameter is optional or it must be an array where each element must be a 'string'; [object Object]"

        Here is my Medata JSON return, please see this file in URL:

        https://onedrive.live.com/redir?resid=17269D19CFD14BB3!3861&authkey=!AIm0ajxNBoSCFyY&ithint=file%2ctxt

        Can anyone help me?

        Thanks very…

        • Fire event on metadata FETCHING (not just fetched

          There is a helpful event for metadataFetched. However, it would be even more helpful to also add an event right BEFORE the metadata request is sent out.

          My use case for this is I am showing textual progress updates on screen, and I would like to update the message when metadata is fetching. I can use the "Fetched" event to show that we are done, but would need a "Fetching" event to indicate when we start.

            • Include Navigation Properties in BeforeSaveAllEntities save maps

              Currently passing entity with navigation properties to the client. Once client modifies the entity or the navigation property entities they come back to the server during save separated making us write more code to perform validation and server side business logic.

              EXAMPLE: I have a class called WorkOrder, Payment and Customer. The structure of the class is as follows:

              WorkOrder
              - WorkOrderID int
              - WorkOrderNumber guid
              - CustomerID int
              - PaymentID int
              - ExclationLvl int

              Payment
              - PaymentID int
              - PaymentType int : reference lookup table called PaymentTypes which has the payment types (ie: Credit Card, Check, Paypal)
              - Amount…

              • Restore foreign keys in dependent entities in rejectChanges()

                When an entity is marked as deleted, and it has dependent child entities, it is removed (set to null) from child entities (even if the foreign key is not nullable). If the delete is cancelled with rejectChanges, the entity is restored to 'unchanged' state, but child entities in cache are not restored. Even requerying the server doesn't fix this (I haven't yet tried specifying overwriteChanges in query options).

                  • NamingConvention for EntityType names

                    The current `NamingConvention` can translate between client and server property names but there is no facility in Breeze to translate between client and server **EntityType** names.

                    For example, if the class on the server is known as `PersonDto`, my client-side EntityType name must also be `PersonDto`. I probably want `Person` on the client.

                    • Support for collections of navigational properties

                      When generating the bundle to be sent to the server on saving of entities I suggest we use this method, I've been using it in the past and haven't seen any issues (yet)

                      function unwrapInstance(structObj, transformFn) {
                      if (!structObj.unwrapped) {
                      structObj.unwrapped = true;
                      var rawObject = {};
                      var stype = structObj.entityType || structObj.complexType;
                      var serializerFn = getSerializerFn(stype);
                      var unmapped = {};
                      stype.dataProperties.forEach(function (dp) {
                      if (dp.isComplexProperty) {
                      rawObject[dp.nameOnServer] = __map(structObj.getProperty(dp.name), function (co) {
                      if (!co.unwrapped) {
                      return unwrapInstance(co, transformFn);
                      }
                      });
                      } else {
                      var val = structObj.getProperty(dp.name);
                      val = transformFn ? transformFn(dp, val) : val;
                      if (val === undefined)…

                      • EntityQuery.withParameters to inject variables into resource name

                        Much like it injects querystring parameters to the request using the object passed to it - it would be nice if it could first look for replacement tokens in the resourceName property of the query.

                        for example:

                        var qry = breeze.EntityQuery
                        .from("Studies/{StudyID}/Sites/{SiteID}/People")
                        .withParameters({StudyID: 123, SiteID: 555});

                        instead, currently, I am doing this:

                        var resourceName = String.format("Studies/{0}/Sites/{1}/{2}", pStudyID, pSiteID, referralName.APIName);
                        var query = breeze.EntityQuery.from(resourceName);
                        ....

                          Thank you very much for TypeScript support for Breeze.js, could I please suggest TypeScript definition for breeze-mongodb for developing with BreezeJS on the MEAN stack (specifically Node.JS)?

                          Again, thanks for all the hard work, this feature will definitely help with adoption for Breeze in enterprises that are developing on the MEAN stack with large scale applications.

                            • Support Paging natively

                              I'm using .take() and .skip() for paging with a table.

                              When I "insert" an entity into the database, I reload my table (new query). Now I would like to jump to this new object inside the table and highlight it.

                              I need an elegant solution to find on what page the new object is and then use skip/take to jump to the correct page.

                              My Suggestion:

                              Maybe Breeze could natively support paging by allowing to specify a page-size in the query and which page to deliver (instead of using take and skip and calculating it on the client).

                              If this…

                                The current implementation of withParameters() only sends those parameters to the XHR implementation, but it does not pass them to the OData provider. The fix is simple, but it's not supported yet. Please implement!

                                • Data Visualualizer

                                  There is no tool unlike SQL Server or EF to help you see what data you are getting back from Breeze. There is no entity inspector. So when you are in javascript and you write repositories it can be a bit of a black hold. Even if the BreezeController.cs has rich annotation and XML comments to show what request are being made.

                                  • Breeze Web API components should support async

                                    Both the Web API and EF 6 support async. All Breeze .NET server components should support async signatures and perhaps should deprecate the synchronous signatures.

                                    • Remove ALL recursive object graphs

                                      Recursive object graphs are extremely bad form, and create havoc for libraries that observe object changes, such as AngularJS. Just try to bind more than a trivial number of entity objects to a control like ng-grid, and you'll instantly hate the performance.

                                      • Create linq like syntax for use with typescript

                                        In jaydata it is possible to generate d.ts files for the entities. It is then possible to write queries like :

                                        northwind
                                        .Products
                                        .filter( product => product.Unit_Price < 50 )
                                        .orderBy ( product => product.Category.Category_Name )

                                        Note that full autocompletion is available for properties.

                                        It would be great to have such a feature in breeze as well.

                                        • Allow for recursive expand and select.

                                          Allow to query recursively on an object type. See https://issues.oasis-open.org/browse/ODATA-38. To take the example from the OData implementation you could query a manager and return the recursive tree of all employees under that manager to a specified number of levels.
