Filtering

Short Description

Dataloy REST API uses a generic search/filtering functionality. In general all resources supports filtering on all properties of that resource and linked resources (for exceptions, see Limitations).

Long Description

Syntax

The filter query parameter has the following format:

<Base URL>/<Resource>?filter=<json property>(OPERATOR)<value>

Example that will return currency information for USD:

localhost/ws/rest/Currency?filter=currencyCode(EQ)USD

Syntax Breakdown

<Base URL>

For more information see Getting Started with Dataloy REST API

<Resource>

Can be any of the Resources available in the Dataloy API.

<json property>

Can be any json property of the resource (for exceptions, see Limitations).

<OPERATOR>

The operator is always:

surrounded by parenthesis
is always upper case

(GT)	Greater Than ONLY numeric and date values		Get all Voyages modified since 2014-01-01 00:00:00, not including 2014-01-01 00:00:00: Voyage?filter=modifiedDate(GT)2014-01-01T00:00:00
(GTE)	Greater Than or Equal ONLY numeric and date values		Get all Voyages modified since 2014-01-01 00:00:00, including 2014-01-01 00:00:00: Voyage?filter=modifiedDate(GTE)2014-01-01T00:00:00

(LKIC)	Like ignore case operator	3.3	Get all BunkerOrder with externalReferenceNo containing the string "test" regardless upper or lower case: BunkerOrder?filter=externalReferenceNo(LKIC)tEsT

<value>

Numeric Values are straight forward. Can be integers or decimal numbers using a dot as decimal point.
Dates must be specified in the format: yyyy-MM-ddTHH:mm:ss
Strings can be surrounded by double quotes, but it is generally not necessary. Even if the string has spaces.
Boolean must be specified with 0 for false and 1 for true.

Combining Filters

The filter URL parameter can be added multiple times to filter on multiple properties in one request. To do so, add a new filter parameter to the end of the URL

Syntax for Combining Filters

<Base URL>/<Resource>?filter=<json property>(OPERATOR)<value>&filter=<json property 2>(OPERATOR)<value>

Example:

<Base URL>/Document?filter=invoicingStatus.statusTypeCode(EQ)RFP&filter=invoicingStatus.statusTypeCode(IN)(INI,INO,CRI,CRO)
 
Invoices ready to be transferred to accounting will be returned.

Properties for Sub Objects

Filters can be used for sub objects by using a "dot path". Example of a sub object is commodity on Cargo:

Part of the Cargo resource as an example: 
 
{
	"cargoReference": 12345,
	"freight": 20000,
	"cargoQuantity":100000,
    "commodity": {
            "commodityName": "Steel",
            "commodityCode": "10000",
            "key": 1069734,
            "self": "http://localhost:8080/ws/rest/Commodity/1069734"
    }
}

To search for cargoes with commodity steel:

<Base URL>/Cargo?filter=commodity.commodityCode(EQ)10000

Limitations
