The model class contains the properties with its getters and setters, while the service class contains the operations to be performed with the model.
For example, if the "Account (CRM_ACCOUNT)" form from the CRM application is used, when downloading the form Java sources, an account.java file is obtained, representing the model and another accountService.java file with the available operations of the service.
Model Class Content
A form model contains:
•Model constructor.
•Getters and setters of its fields.
•Inner classes that represent the “Multiple occurrences” containers model, if any.
Specific method of the model class
In addition to the getters and setters, there are specific methods related to fields.

Examples of Use
The examples use the "Account (CRM_ACCOUNT)" form of the CRM application and each example contains the use of "Account" model class and "AccountService" service class.
1. Service creation
This service is created only once in the rule and is reused in different operations.
AccountService accountService = new AccountService(getApiClient()); |
2. Create a form instance
An instance of “Account” model class is created, values are assigned to its properties. Using the “AccountService” service class, the new account is saved with the assigned values through the create (account) method.
Account account = new Account() ; Integer accountNumber = accountService.create(account); log("Account created with account number:"+ accountNumber);
|
3. Read a form instance
To obtain data from an existing account, an "Account" model class instance is created, an identifier chosen through the corresponding setter is indicated and such instance is read using the read(account) method of the “AccountService” service class. The instance contains all its properties which can be queried using the corresponding getters. The example reads the dsCompany, dtOpening, dtStore, and dtLastUpdate properties.
Account account = new Account(); Integer readAccountNumber = 50000 ; |
4. Modify a form instance
To modify data from an existing account, an "Account" model class instance is created, an identifier chosen through the corresponding setter is indicated and such instance is read using the read(account) method of the “AccountService” service class. The dsCompany property is then modified using the corresponding setter and the update(account) method of the service is invoked to update the account.
Account account = new Account();
|
5. Delete a form instance
To delete an existing account, an instance of the "Account" model class is created, indicating its identifier by means of the corresponding setter. The delete(account) method of the service is then invoked to delete the instance.
Account account = new Account(); account = accountService.read(account);
|
6. Use of file and image type fields
To retrieve a file related to a form instance, use the corresponding get+<fieldname>+(entity) method of the "AccountService" service class.
In this example, the getFlLogo(account) method of the "AccountService" service class is invoked, which allows to retrieve the file corresponding to a logo associated with a File object.
Account account = new Account(); |
7. Use of internal objects
Internal objects represent the set of fields modeled in containers of multiple occurrences.
In this example, two new “Account.PhoneLine” internal objects are instantiated and values are assigned to their nrPhone and tpPhone properties.
A new list of “Account.PhoneLine” objects can be saved with the setPhoneLine(lsPhones) method or by adding two instances of the “Account.PhoneLine” object to the current list.
|
8. Reading of cases associated with form instances
The example retrieves the case associated with a form instance and executes that case.
To use this example in addition to the "Account" (Account) form, the "Account Registration" (Account Registration) process that uses that form must be modeled. The case can be started manually or via Deyel SDK methods.
To read cases associated with a form instance, an instance of the "Account" model class is created, indicating the identifier chosen by means of the corresponding setter. The "AccountService" service is instantiated and using the readCases(account) method, the "Cases" list is retrieved with the cases associated with the instance with identifier 10.
Having the “Cases” list, it is possible to iterate through it to retrieve some or all of its cases. The “AccountRegistration” service is instantiated and using the execute(accountRegistrationCase) method, the first associated case is executed.
Both the form instance and the case instance must be created.
Account account = new Account(); account.setId(10);
AccountService accountService = new AccountService(getApiClient()); List<Cases> listOfCases = accountService.readCases(account);
AccountRegistration accountRegistrationCase = (AccountRegistration) listOfCases.get(0);
AccountRegistrationService accountRegistrationService = AccountRegistrationService(getApiClient()); accountRegistrationService.execute(accountRegistrationCase);
|
9. Associate a case with a form instance
In the example, a case associated with an "Account" form instance is read to then associate such case to a "Contact" form instance, leaving both instances associated with the same case.
The case associated with the "Account" form instance is read with the readCases(account) method, described in example 8.
The case is associated with the "Contact" form instance, with the bind(contact,accountRegistrationCase) method.
A case can only be linked to a form instance if there is a relation between the form and the process to which the case to be associated belongs.
Account account = new Account(); account.setId(10);
AccountService accountService = new AccountService(getApiClient()); List<Cases> listOfCases = accountService.readCases(account);
AccountRegistration accountRegistrationCase = (AccountRegistration) listOfCases.get(0); AccountRegistrationService accountRegistrationService = AccountRegistrationService(getApiClient());
Contact contact = new Contact(); contact.setId(20);
ContactService contactService = new ContactService(getApiClient());
contactService.bind(contact,accountRegistrationCase);
|
10. Retrieve the code and description of the field value associated with a value list
In order to use this example, model the “States” value list in Deyel and beforehand, enter values to this list.
Code |
Descriptive Value |
|---|---|
1 |
Active |
2 |
Inactive |
It is required to relate an “Account” form field with the “States” value list.
When a field has a relation defined, the content can use its code or its descriptive value.
This example retrieves the field code associated with the value list.
String stateCode = account.getAccountState(); //Returns: 1
|
While in the following example, the description of the field associated with the value list is retrieved.
String stateDescription = accountService.getAccountSate_description(account); //Returns: Active
|
The code is retrieved through the model object and the description is retrieved through the service object.
Search
A search on a form instance can be performed using the following objects.
Criteria- represents search criteria on form data. It is made up of elements that can be fields and values, connected by operators.

|---|---|
eq |
Equal |
neq |

SearchCriteria: object that groups search criteria (Criteria object), it also allows parameterizing the order of the result, the size of the reading page and the number of pages to be retrieved. Reading by pages is used since the data volume on a form can be very large.
Form Service: service class of the form on which the search is being carried out. Contains the search(searchCriteria) operation that must receive the SearchCriteria object as a parameter and returns the SearchResult object.
Example:
SearchResult searchResult = accountService.search(searchCriteria);
SearchResult: object that contains the search results. Contains a list of form instances, which are instances of the corresponding model, for example "Account". This object allows to know the total number of reading pages resulting from the search, the size of each page and the number of pages to retrieve.
Examples
1. Search
This example retrieves a list of active state accounts, where such state corresponds to code "1". A quantity of 15 lines per reading page and the number of pages to retrieve are defined. The results are sorted by company name in ascending order.
|
2. Constructor types for search criteria
This example creates a Criteria object and defines different search conditions using the equal, different, greater, greater equal, less, less equal, between, among, and allows equals, out of range, and contains operators.
// Equal cdStatus= 1 corresponds to an active account
|
Deyel uses the data type java.sql.Date for "date" type fields, so the transformation from java.util.Date to java.sql.Date must be done, when it is required to create an object with this type of data.
// Contains |
3. Operations on the results object
The SearchResult object is an iterative object and as such can be scrolled through in different ways.
The example uses a FOR statement to iterate over each of the instances that meet the search conditions of the dsIndustry and qtScore properties, retrieving the idAccount and dsCompany properties.
SearchCriteria searchCriteria = new SearchCriteria(); |
Navigation between Related Entities
In the CRM application, the “Contact (CRM_CONTACT)” form has a relation with the “Account (CRM_ACCOUNT)” form and the related account can be retrieved from a business rule, from a contact.
An instance of the “Contact” model class is created and the account identifier is retrieved using the corresponding getter.
Next, an instance of the "Account" model class is created indicating the identifier retrieved from the contact in the setter and the account instance is read using the read(myAccount) method of the "AccountService" service class.
Contact contact = new Contact() ;
