Get a record, with specified fields.
- Syntax
- <syntaxhighlight lang="java" enclose="div">
Result result = Functions.getRecord(String objectName, String fields, String recordID
{, Parameters params} );
</syntaxhighlight>
- Parameters
-
- objectName
- An Object Identifier
- fields
- The fields to retrieve.
- A comma-separated list of field names (Use the REST API:field Resource to get a complete list of fields.)
- The asterisk ("*") wildcard specifies all fields.
- For related-record fields in a Composite Object, specify the alias of the related object and the field name, where the alias is defined in the Object Relationships:
- alias[.alias...].* or alias[.alias...].field
- When fetched, an alias becomes a virtual "field" that contains an array of records from the related object, where each record contains the specified field(s).
- alias.* specifies all fields in the aliased object.
- recordID
- A Record Id.
- params
- An optional com.platform.api.Parameters object. Use it to specify the Retrieve Record Permissions Parameter, in order to find out if the user has update or delete permissions on the record.
- Return
- Result object. If the return code is greater than zero, use the getParameters() method to get a Parameters object with the record's fields. (See the Java Code Samples for multiple examples of the getRecord API.)
- For a Composite Object relationship, the relationship alias becomes a "field" in the Parameters object. That field contains an ArrayList of embedded Parameters objects, one for each related record.
- Composite Record Example
- This example assumes that a relationship has been established between Cases and a Contacts object, where Contact records have an email field and a Lookup to Cases. With that relationship, multiple contacts can be associated with a case. (In this example, the name of the alias relationship is assumed to be "contacts", matching the name of the object.)
- <syntaxhighlight lang="java" enclose="div">
// Get the status field and two composite fields for a specified case record. // Composite fields are identified as <alias>.<field1>, <alias>.<field2>, etc. // The returned structure contains an array of Parameters for the "alias", where // each Parameters item contains the fields from a related Contact. recordID = ...; Result result = Functions.getRecord("cases", "status,contacts.name,contacts.email", recordID); if (result != null && result.getCode() == 1) {
Parameters params = result.getParameters(); if (params != null) { // Get the case status String caseStatus = params.get("status"); // The "contacts" field contains the array of Parameters for associated Contacts. // Each entry in the array contains the fields for one record. // Here we get just the first entry from the array. (Loop to get them all.) ArrayList caseContacts = (ArrayList)params.getObject("contacts"); HashMap contactParams = (HashMap)caseContacts.get(0); // Get first entry String name = (String)contactParams.get("name"); // Get the fields String email = (String)contactParams.get("email"); }
} </syntaxhighlight>
