* GraphQL Object constraints
Implements the GraphQL Object constraints, which allows us to filter queries results using the `$eq`, `$lt`, `$gt`, `$in`, and other Parse supported constraints.
Example:
```
query objects {
findMyClass(where: {
objField: {
_eq: {
key: 'foo.bar',
value: 'hello'
},
_gt: {
key: 'foo.number',
value: 10
},
_lt: {
key: 'anotherNumber',
value: 5
}
}
}) {
results {
objectId
}
}
}
```
In the example above, we have the `findMyClass` query (automatically generated for the `MyClass` class), and a field named `objField` whose type is Object. The object below represents a valid `objField` value and would satisfy all constraints:
```
{
"foo": {
"bar": "hello",
"number": 11
},
"anotherNumber": 4
}
```
The Object constraint is applied only when using Parse class object type queries. When using "generic" queries such as `get` and `find`, this type of constraint is not available.
* Objects constraints not working on Postgres
Fixes the $eq, $ne, $gt, and $lt constraints when applied on an Object type field.
* Fix object constraint field name
* Fix Postgres constraints indexes
* fix: Object type composed constraints not working
* fix: Rename key and value fields
* refactor: Object constraints for generic queries
* fix: Object constraints not working on Postgres
* Removes need to use babel-register
- Adds watch to watch changes when running the test to regenerate
- Tests are now pure node 8
* Adds timing to helper.js
* Update contribution guide
* Adds inline sourcemaps generation to restore coverage
* nits
* chore(package): update jasmine to version 3.0.0
Closes#4547
* Fixes failing tests for jasmine 3.0
Starting 3.0, done(something) will fail
* Update tests so they dont leverage var, but let and const
With jasmine 3.0, the randomization engine was making the test fails because of the scope of `var`
* Remove randomizer
* Use same adapter for PG tests, drop table to ensure the tests dont side effect
