yawp's Issues

Problem when has an method in Action

Hello,

Apply the attached file and run tests.
diff-yawp.txt

One solution would be to not scan methods that don't have any annotation.
io.yawp.repository.EndpointScanner.scanActions() - L 154, before add

private void scanActions() {
        Set<Class<? extends Action>> clazzes = endpointsPackage.getSubTypesOf(Action.class);

        for (Class<? extends Action> actionClazz : clazzes) {
            Class<?> objectClazz = ReflectionUtils.getGenericParameter(actionClazz);

            if (objectClazz == null) {
                continue;
            }

            for (Method method : actionClazz.getDeclaredMethods()) {
                if(method.getAnnotations() != null && method.getAnnotations().length > 0) {
                    addAction(objectClazz, method);
                }
            }
        }
    }

Create a "static import API" for yawp Java client

Swagger definition Scaffolder

Add an options in the yawp-maven plugin to scaffold endpoints and actions from a Swagger definition file:

mvn yawp:swagger -Dfile=swagger-api.json

A nice test would be to scaffold this API: http://petstore.swagger.io/v2/swagger.json

Allow Hook hierarchy on user code

Today it is not possible.

Example: ValidationHook extends Hook

Then: PersonValidationHook extends ValidationHook

Isolate appengine dependency to support different environments

Support multi-part paths for Endpoints

For example:

@Endpoint(path = "/store/orders")
public class Order

This will be useful to organize APIs into a tree-like structure.

Stop adding extra attributes to user defined HttpException

Use as the response body the user defined text/object (json serialized) without any modifications.

Think about add an option for mime-type.

Automated test for an archetype project creation

Check if the right driver is always loaded.

Create a Hook transaction model

Today it is possible to create your own model using hooks in a specific way.

This issue is to think about another approach, more fluent and specific.

Improve API Javadoc documentation

Improve Action signature support

Think about allowing parameters such as Objects (parsed from json body), Request Json, Request Context.

@matheusmr13 ;)

Add support for patch in yawp.js

Shielding every method of an endpoint action

invalid json query using boolean

yawp('/entity').where(['availble', '=','true']).list(function(l){console.log(l)})

Support generic superclass @Id for composed endpoints

Provide an public EndpointTestCase as base class for tests

IdRef.compareTo(IdRef<T>) bug when using id creating using name

How to reproduce:

User john = new User();
john.setId(IdRef.create(yawp, User.class, "[email protected]"));
john = yawp.save(john);

john.getId().compareTo(mary.getId());//Mary is other user created using the same process

Support all verbs in Actions

Today it is only possible to use @put and @get...

Create an API for transactions in Repository to use in custom actions

Descritive error messages when dev

Eg: "404 sent by shield"

Create a way to customize kind names for a project

Maybe a env variable defining a handler class. Don't like the idea of having an attribute in the @endpoint.

Composed Transformers

Bug in method frist() or limit(1)

When executing:

yawp(Extrato.class).where("contaCorrenteFisicaId", "=", contaCorrenteFisica).and("data", "=", LocalDate.now().minusDays(1).toDate())
.first()

Returns null.

yawp(Extrato.class).where("contaCorrenteFisicaId", "=", contaCorrenteFisica).and("data", "=", LocalDate.now().minusDays(1).toDate()).limit(1)
.list()

Returns empty list.

yawp(Extrato.class).where("contaCorrenteFisicaId", "=", contaCorrenteFisica).and("data", "=", LocalDate.now().minusDays(1).toDate())
.limit(2).list()

Returns a list with one Extrato.

In the datastore, I have saved two Extrato's instances, with same "data" (java.util.Date), and diferents "contaCorrenteFisicaId" (IdRef).

Apply parent shield on childreen/grandchildreen (...) routes

Json parser (in transformers) is getting private fields

Use a JavaBean JSON parser instead would be more secure.

Support Void Actions

This is not well thought yet. But we may need to be able to create APIs like:

GET /store/inventory

This actions does not have an explicit endpoint model, although it could be something associate with an product model, like:

GET /products/inventory

Some ideas:

Allow route re-write or alias for action routes (think about the API)
Allow Actions for "None" endpoints: extends Action<Void>

Add simple attribute filter to Index/Show Rest Actions

Imagina an Endpoint:

public class Person {
  @Id
  IdRef<Person> id;

  @Index
  String name;

  @Index
  IdRef<Address> addressId;
}

We can have an automatic API like this: /api/people?name=john.

Finally, if it is an IdRef attribute, we can convert it automatically: /api/people?addressId=10

Today it is possible to achieve those simple APIs with the aid of a Hook.

Defaults shield

If I have an Endpoint with an Action, and all but one method has the same permisson to data, it would be usefull to have and default method in the shield, that will be called whenever an especific shield is written.

Support cross domain setup via yawp.yml and/or servlet init options

We need a way to fully customize the cross domain behavior. Today we have only this (EndpointServlet):

if (enableCrossDomain) {
    resp.setHeader("Access-Control-Allow-Origin", "*");
    resp.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
    resp.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT, OPTIONS, DELETE");
}

Create a "beforeShield" phase in hooks

Composed Hooks

Cache API

Think about: for transformers, single entities, actions, uri based?

Composed Actions

Support json array for update/patch

Example:

PUT /people [ { id: '/people/1', name: 'x' }, { id: '/people/2', name: 'y' } ]

All objects must have an id and they must be of the same endpoint type.

Real PATCH behaviour

Fetch entity before update (when method=patch), merge changes only for fields present in json, follow the update flow as normal.

Tutorial & Further Documentation

Hello,

Could you create a short tutorial from setting up to developing a simple API using YAWP? In addition, is it possible to customise the GET/POST/etc. of a POJO or even disable specific ones to only allow GET for example?

Thanks,
Daniel

Support params as application/x-www-form-urlencoded

The request handler is trying to parse the body as JSON.

Query using "IN" condition returns null cursor

Checkout the test bellow:

@Test
    public void testQueryUsingINCursorReturnsNull() {
        Child child = yawp.save(new Child("xpto1", yawp.save(new Parent()).getId()));
        Child child2 = yawp.save(new Child("xpto2", yawp.save(new Parent()).getId()));

        DatastoreQuery<Child> query = yawp(Child.class).limit(1);
        List<Child> list = query.list();
        Assert.assertEquals(1, list.size());
        Assert.assertNotNull(query.getCursor());

        DatastoreQuery<Child> query2 = yawp(Child.class).where(c("id", "in",Arrays.asList(child.getId(), child2.getId())));
        List<Child> list2 = query2.list();
        Assert.assertEquals(2, list2.size());
        Assert.assertNotNull(query2.getCursor());///fail
    }

Create a blob API to allow file upload

Support file upload and blob storage for models.

Allow different Date/Timestamp formats

Allow for the whole API.
Think about allowing for specific endpoints and/or fields.
