Add method "SaveChanges" on EntityAspect
It would be nice if there is a method "SaveChanges" directly on the EntityAspect, similar to "RejectChanges". This makes it easier to save this and only this entity without affecting other entities that might have been changed. I know that there is a parameter on the EntityManager.SaveChanges(...) method, but having it directly on the EntityAspect makes it a little more convenient.

breeze.js createError function can't handle datajs errors
My ODataController Post method was updating its entity's CreatedOn property with DateTime.Now value before it's saving to database.
Apparently datajs doesn't like DateTime.Now value and gives an error with "Invalid date/time value".
File: datajs-1.1.2.js - Line 2133
After datajs throws the exception, it falls to breeze.js createError function. However, since it's expecting error.response property, it fails to continue by giving "response is undefined" message.
File: breeze.debug.js - Line: 15302
I've updated the function by adding a check for response property;
function createError(error, url) {
// OData errors can have the message buried very deeply - and nonobviously
// this code…11 votes -

BreezeJS and Moongose
Hi All,
I am new to MEAN stack, I am to easily for Moongose based apps and developed rapid prototypes in less than 30 mins, but with Zaa example even though I can run the sample in 10 mins. The concept of metadata generation with respect to MEAN stack very confusing, where as for .NET MVC example I can easily understand.

Flag which navigation properties have been loaded
It's currently not possible to determine if a navigation property has been loaded.
For example a order.orderLines. There is no way of knowing whether orderLines is empty because the order has no lines or that the navigation property has been loaded.
This is a real pain when you have business logic that require the object graph to be loaded. This leads you to implement boiler plate data access related code to manually track which navigation property has been loaded - something that the breeze framework should be doing.
This feature has been asked for on SO here: http://stackoverflow.com/questions/17798514/any-way-to-tell-if-a-breeze-navigation-property-has-already-been-loaded

Breeze + Knockout validation -> new features
If App uses breeze and ko validation, I suggest to
add knockout validation rules for every fetched entity as showed in code example (here coffee code implementation for dataPropeties):
addRules = (breezeEntity) ->
return if breezeEntity.koValidationRulesAdded
entityType = breezeEntity.entityType
for property in entityType.dataProperties
continue unless property.validators.length > 0
do (property) ->
displayName = property.displayName or property.custom?.displayName or property.name
breezeEntity[property.name].extend
validation:
validator: (value) ->
if breezeEntity.entityAspect.validateProperty property.name, {displayName: displayName, entity: breezeEntity}
@message = ""
return true
else
@message = breezeEntity.entityAspect.getValidationErrors(property.name)[0].errorMessage
return false
message: ""
return
breezeEntity.koValidationRulesAdded = true
returnthis code allows:
1) to validate single property with usage of all…5 votes -
Tools for meta data creation for breeze not depending on a server-side ORM and tools for ORM-less server-code generation
For me ia server-side ORM for a web application is a wrong cut. I think business logic should go as close to the data as possible to guarantee consistency, protection, and security. This means to me using stored procedures and database functions wherever possible (in a relational environment) and reasonable. In addition, if done right it's arguably unbeatably fast. The role of the Web API should be to provide access to the data across the network but not processing it.
Let's suppose we have to query the database for all open orders for a certain customer including order items and…

Specify the version of Express to install in the Zza Example
Express v4 differs a bit and will not work with the Zza Example. One recommendation would be to change the instructions until the express code is updated to: npm install express@3.5.1
Once the code is updated to support Express v4, remove that specific version from the instructions.

Better non MS support
Compared with other data client libraries Breeze is way ahead but it is still heavily tied to MS. It says it supports most dbs out the box but this is a bit misleading as you need a .NET provider which really means Windows. I've mainly worked on MS technologies but recent requirements mean a lot of our systems run on Linux and I'd like to use Breeze for this.

Fix Navigation Property Update When Changing a Composite Foreign Key
In an entity that has a navigation property based on a composite foreign key (i.e. based on more than one foreign key properties), when setting one of the FK properties, breezejs tries to update the navigation property, however it searches for the foreign entity using a single key instead of a composite key, so it never finds the property.
To see what I mean and for a possible fix, please refer to breeze.debug.js (v.1.4.8) lines 4907 and 4908:
key = new EntityKey(relatedNavProp.entityType, [newValue]);
relatedEntity = entityManager.findEntityByKey(key);The related entity never gets found since the key consists only of a single…

Support filters for multi-level relationships with derived types
Support filters for multi-level relationships with derived types, as in the currently valid OData 3 filter syntax:
BaseModel/derivedmodel.namespace.on.server/DerivedModelPropertyCurrently this almost works if you specify the property name as above, except that it always defaults the data type of the predicate to string, even if a data type is specified. This is due in part to the syntax failing the RX_IDENTIFIER check.

optimize/compress data/bandwidth using nested arrays of values only
Instead of current JSON format used to send data from server to client, optimize it so that only values are sent in an array (or nested arrays) - no need to send field names if schema is available, otherwise send a separate mini-schema (list of fields/types) along the data. Decode it on the client back to the current structure.
This is especially important when trying to limit the data sent back using Select on the server (anonymous entities), each row includes a complete data type as a very long string - with many rows, this adds substantial overhead (almost always…2 votes -
