Breeze js requests metadata without needing to make a second call to the server

Currently, I am developing an Angular application that utilizes Breeze JS and ASP.NET OData controller. While testing, I encountered an issue where Breeze JS successfully makes the initial call to retrieve metadata from the server but fails to make the second call to fetch the actual data. In Chrome's developer tools, I can see the following XHR request:

XHR finished loading: GET "http://localhost:31549/Odata/ClientInvestments/$metadata".

This request returns an XML response detailing the structure of the data entities.

However, subsequent calls for the data itself seem to be unsuccessful. My Web API configuration includes routes for various OData services along with specific formatters and message handlers to process the requests efficiently.

In my JavaScript code, I have configured Breeze JS to work with the OData service endpoint related to Client Investments. Using an EntityManager and querying the 'ClientInvestments' entity set should ideally return the desired data, but currently, it does not. The corresponding OData controller for Client Investments is structured according to authorization rules and query methods to fetch the necessary information securely.

Answer №1

When using the EntityManager's executeQuery method, it's important to remember that it operates asynchronously and returns a promise. To properly handle the response, you should invoke it in the following manner:

manager.executeQuery(query).then(function(data) {
  var results = data.results;
}

Answer №2

If you're unsure about the effectiveness, consider testing the query in different ways:

var query = breeze.EntityQuery
    .from("CustomerOrders"); 
manager.executeQuery(query);

Alternatively, you can try it like this:

new breeze.EntityQuery()  
    .from("CustomerOrders")
    .using(manager)
    .execute();

It's important to note if OData is the appropriate dataservice, or if webApiOData would be a better fit.

Answer №3

It's important to review your CORS settings occasionally as Breeze may encounter silent failures if the configuration is incorrect.
