Hi,

 

You can not create custom object and its field by apex. You can only retrive object and field information using apex.

Hi,

 

Yes, You can create custom object and custom object fields using Apex code.

 

Step 1: You have to first insert MetadataService and MetadataServiceTest controller in your organization.

Link for That classes are as below In developer console.

MetadataService controller

MetadataService Test controller

 

Step 2: Then execure below code.

see below example.

 

Create Object using apex Code:

MetadataService.MetadataPort service = new MetadataService.MetadataPort();  
service.SessionHeader = new MetadataService.SessionHeader_element();
service.SessionHeader.sessionId = UserInfo.getSessionId();

List<MetadataService.Metadata> fields = new List<MetadataService.Metadata>();
MetadataService.CustomObject  customobject = new MetadataService.CustomObject();
customobject.fullName = 'custom_create__c';
customobject.label = 'Custom created object';
customobject.pluralLabel = 'Custom created objects';
customObject.nameField = new MetadataService.CustomField();
customobject.nameField.type_x = 'Text';
customobject.nameField.label = 'Custom created field';
customobject.deploymentStatus = 'Deployed';
customObject.sharingModel = 'ReadWrite';
fields.add(customobject);

MetadataService.AsyncResult[] results = service.create(fields);

 

 

Create Field using apex Code:

MetadataService.MetadataPort service = new MetadataService.MetadataPort();  
service.SessionHeader = new MetadataService.SessionHeader_element();
service.SessionHeader.sessionId = UserInfo.getSessionId();

List<MetadataService.Metadata> fields = new List<MetadataService.Metadata>();
MetadataService.CustomField customField = new MetadataService.CustomField();
customField.fullName = 'custom_create__c.custom_create_field__c';
customField.label = 'Custom created field';
customField.defaultvalue = 'false';
//customField.sharingModel = 'ReadWrite';
customField.type_x = 'Checkbox';
fields.add(customField);

MetadataService.AsyncResult[] results = service.create(fields);

Hi

i am getting below mentioned error, when try to use above steps to create a Custom Object

Compile error at line 15 column 41 Method does not exist or incorrect signature: [MetadataService.MetadataPort].create(List<MetadataService.Metadata>)


Please suggest me what kind of setting is required to execute above steps and please note i am using Eclipse 3.6 force.com IDE.

Regards
Sumit

The method should not be 'create' change it to createMetadata and it should work fine. Also you may get an error for IO Exception and will need to do Remote Site Settings to enable it.

Hi All...
Just referred this thread for creating custom settings automatically on sandbox refresh, and it runs perfectly using below code-

For custom Settings- 
List<MetadataService.Metadata> fields = new List<MetadataService.Metadata>();
MetadataService.CustomObject  customobject = new MetadataService.CustomObject();
customobject.fullName = 'custom_settings1__c';
customobject.label = 'Custom settings1';
customobject.customSettingsType='List';
fields.add(customobject);

MetadataService.SaveResult[] results = service.createMetadata(fields);
system.debug(results);
For custom object- 
List<MetadataService.Metadata> fields = new List<MetadataService.Metadata>();
MetadataService.CustomObject  customobject = new MetadataService.CustomObject();
customobject.fullName = 'custom_create__c';
customobject.label = 'Custom create object';
customobject.pluralLabel = 'Custom created objects';
customObject.nameField = new MetadataService.CustomField();
customobject.nameField.type_x = 'Text';
customobject.nameField.label = 'Custom created field';
customobject.deploymentStatus = 'Deployed';
customObject.sharingModel = 'ReadWrite';
fields.add(customobject);

MetadataService.SaveResult[] results = service.createMetadata(fields);
system.debug(results);

Hi yarram,

For creating Object and field using apex code firstly you have to insert  MetadataService controller and MetadataService Test controller
in your organization.

If you find your Solution then mark this as the best answer.

Thank you!
