Unit management

Manage Units

Finding units by filters with sorting and paging

get

Retrieves a list of units conforming with the given filters. Supports sorting and paging.

  • If the Accept-Language is set to * each internationalized field is returned as a map that contains all of translations in a format of key:value pairs, where the key is the language code and value is the translation.

  • The Accept-Language can contain the priority list of languages which should be returned. Always one language is returned as a single string field. Example: 'fr-CH, fr;q=0.9, en;q=0.8, de;q=0.7'

  • If the Accept-Language header is empty default language defined in the Configuration service is taken.

  • If the unit name matches none of the specified languages, an empty string is returned in the name field.

Please, see the examples below.

Authorizations
Path parameters
tenantstringRequired

The tenant name.

Example: testtenant
Query parameters
paramsstringOptional

Note: params is not a name of query param. Any API model field can be taken as a filtering parameter.

Filtering can be done by each field available in API. Filtering by multiple fields is also allowed. In that case, fields are aggregated with AND logic operator. In the case of string values, the contains approach is taken (filtering by substrings). In the case of boolean and number fields, the equals approach is taken.

Filtering query params examples:

  • type=mass - all units with type that contains mass are returned. For example, in that case all mass units will be returned.
  • type=a - all units with type that contains a are returned. For example, in that case all mass and distance units are returned.
  • factor=1 - all units with factor that equals 1 are returned.
  • baseUnit=true - all units with baseUnit that equals true are returned.
  • type=mass&name=gram - all units with type that contains mass AND name that contains gram are returned. For example, in that case kilogram, gram, decagram units are returned.

Filtering by localized fields:

  • Filtering by localized fields without language key is possible only when Accept-Language header with correct language is provided or when it is not set at all (in that case default language is taken). For example, when Accept-Language' is set to 'en', the request with parameter name=meterreturns all units withnamethat containsmeterin English. For example, in that casemeter, kilometerandmillimeter` units are returned.

  • When Accept-Language header is set to * filtering by localized fields is possible only when fields contains language key. For example, when Accept-Language is set to '*', the request with parameter name.en=meter returns all units with name.en that contains meter in English. For example, in that case meter, kilometer and millimeter units are returned.

Example:
sortstringOptional

Fields to sort the response data by following order of the parameters from left to right. Can contain multiple fields in format: field name:sort direction separated by a comma. The colon with sort direction parameter is redundant and descending order is taken only if it is equal to desc or DESC. Ascending order is considered in any other case. Sorting by name parameter works properly only if the Accept-Language header is set to a specific language or is empty with default language specified in the configuration service.

Example: name,factor:asc,metadata.createdAt:desc
pageNumbernumberOptional

The page number to be displayed.

Example: 1
pageSizenumberOptional

Number of units on a single page.

Default: 60
Header parameters
Accept-LanguagestringOptional

The Accept-Language request HTTP header defines which languages the client is able to understand, and which locale variant is preferred. If empty, English language is returned. It can be a priority list working as a fallback mechanism.

Example: fr-CH, fr;q=0.9, en;q=0.8, de;q=0.7
X-Total-CountstringOptional

Total count flag. If set to true X-Total-Count header is returned.

Example: true
