breeze.js：如何从微风元数据集合中排除表/实体？

Question

I have a Single-Page application using Entity Framework on the backend and Breeze.js on the client. I'm also using the breeze .Net EF classes. In order for the breeze client to create breeze entities on the client, it calls a controller method named "MetaData". This method returns a collection of all the entities in the database, even those that may not be used on the client.

Even though there is no coding logic in the metadata, it does contain a complete schema of the database. Some of these entities are used for security and business logic, and I wish to not have this entire structure open to the world.

Is there a way to exclude entities (not just individual properties) from the breezejs metadata collection?

Thanks

The easy way is to create a DbContext that has only those classes and relationships that you want to expose. Use the fluent interface to shrink it down and cauterize relationships that you don't want.

Then create an instance of an EfContextProvider based on this limited DbContext .

You can use this cut-down DbContext exclusively for metadata generation if you wish. You can switch to something more robust (wrapped in a different EfContextProvider ) if you must.

See the documentation chapter "EF as a Design Tool" .
