It doesn't convert to enum in case of "in" and "out" queries.

And exception as a result:

Create a rql sort api parser

Implements converters from rsql-parser to Querydsl sets of Path types such as DatePath, DateTimePath, StringPath, EnumPath, NumberPath, BooleanPath, CollectionPath, TimePath,etc.

Hi,

Is it possible to have an expression like employee.company_id == company.id ?

i.e. having a path on both sides of the expression?

Provide support of rql select for mongodb

Integration Spring Data Pageable with querydsl page and sort modules

rql syntax that supports jpa aggregation, having ang groupby

Provide rql select,, filter, page and sort api support for Querydsl Mongodb

Using a generic DSL API, this shields users from internal implementations and any future refactoring.
Also refactor querydsl modules. split into major modules such as mongodb and jpa implementations.

Querydsl implementation for rql select using querydsl projection

Waiting for OSSRH approval to be able to publish 1.0.0.M1 milestone release to maven central.

Is it possible to query by relationship (using spring-data-mongodb)?

I've an Item Model and an Item belongs to a Category. I would like to query the items by category.id=={id}.

I already added these path mappings but the results are always empty.

.put("category", QProduct.item.category)
.put("category.id", QProduct.item.category.id)

Hello,

You have here a very interesting project that I would like to use. My question is, does it work with last version of QueryDSL SQL 4.1.0?

Thank you.

Create a querydsl integration with rql page api

I always need to map type -> QEntity.entity.type, type.value -> QEntity.entity.type.value, etc.
Is there a way to not explicitly specify all mappings as I want this to work for all class properties and paths and I have many entities. I can easily create a method that generates from a string a class path through reflection but I'll need the mapping object to be a closure that takes (String path, Class qclass ) and return the Path object instead of a static Map.

First of all, great job!

The spec in http://doc.apsstandard.org/2.1/spec/rql/ mandate dates to be in ISO UTC format. This also is the date format on the JSON spec and the format returned by JS Date.toJSON. This means the DateUtil class should not fail on strings like 2016-07-17T02:59:59.999Z.

The thing, though is how that it converts to a LocalDateTime. I'm not sure if dropping the time zone info (the Z in the string) is always the correct solution since some masochists developers might use something different than UTC for their timezone.

Hello
It seems like the PathConverterContext con't be extened to supprot other path types, like UUID for example. My filter looks like this : uuidField=='CED17E16-78AF-47F6-8ACB-CF5CEEBBF8DB' where uuidField field is defined as private UUID uuidField.
The QuerydslRsqlVisitor::visit method fails with NullPointerException because PathConverterContext.getOperator(path) return null for UUID type.
Is there any workaround to overcome this ?
Thanks

This looks like a nice library. Could you please add a license file or statement indicating what the licensing of this code is. For example, the RSQL project on which this is based is MIT License.

Thanks.
