CREATE CUSTOM METADATA USING APEX

Question

I wrote a little code that creates metadata custom type:

public class CreateUpdateMetadataUtils implements Metadata.DeployCallback {

public void handleResult(Metadata.DeployResult result, Metadata.DeployCallbackContext context) {
    if (result.status == Metadata.DeployStatus.Succeeded) {
        System.debug(' success : '+ result);
    } else {
        System.debug(' fail : '+ result);
    }
}

public static void createUpdateMetadata(String fullName, String label, Map<String, Object> fieldWithValuesMap){
    Metadata.CustomMetadata customMetadata =  new Metadata.CustomMetadata();
    customMetadata.fullName = fullName;
    customMetadata.label = label;

    for(String key : fieldWithValuesMap.keySet()){
        Metadata.CustomMetadataValue customField = new Metadata.CustomMetadataValue();
        customField.field = key;
        customField.value = fieldWithValuesMap.get(key); 
        customMetadata.values.add(customField);
    }

    Metadata.DeployContainer mdContainer = new Metadata.DeployContainer();
    mdContainer.addMetadata(customMetadata);
    CreateUpdateMetadataUtils callback = new CreateUpdateMetadataUtils();
    Id jobId = Metadata.Operations.enqueueDeployment(mdContainer, callback);
}}

I ran it via "execute anonymous window" with this code:

Map<String, Object> maptest = new Map<String, Object>();
maptest.put('Is_Admin__c',true);
maptest.put('Profile_Full_Name__c','Admin');
maptest.put('Profile_Name__c','Admin');
maptest.put('Updated__c',false);
CreateUpdateMetadataUtils.createUpdateMetadata('Profile_Setting.TEST_SARA','TEST_SARA',maptest);

but nothing happened! :(

here is my log:

Using Apex Metadata API, one can create two metadata types: page layouts and the records of custom metadata types. You can create Custom Metadata Type records NOT the Custom Metadata Type Metadata.

Firstly, one has to go to Salesforce Setup to create the Custom Metadata Type with all its fields. Then using Apex MetaData API one can create the records of newly created Metadata Type. I created a Custom Metadata Type named Profile_Setting__mdt in my org before calling the Apex Metadata API.

To verify whether the Custom Metadata Type Records are created or not, Please go to Setup->Develop-> Custom Metadata Type. Then click on the Manage Records to see newly created records.

The Trailhead module https://trailhead.salesforce.com/content/learn/modules/apex_metadata_api explains the concept very clearly.

The problem with the original code provided by the user is not in the modular pattern defined by the Salesforce. The below code is easy to understand and modular. The user was not getting any output because he did not create the **Custom Metadata Type declaratively using Salesforce Setup

Here is the working pattern based on the Salesforce Trailhead module on Apex Metadata Type.

Class Name - createUpdateMetadata

        public class createUpdateMetadata{

    public Metadata.CustomMetadata createCustomMetadata(){
       Metadata.CustomMetadata customMetadata =  new Metadata.CustomMetadata();
       customMetadata.fullName = 'Profile_Setting__mdt.TEST_SARA'; 
       customMetadata.label = 'Master Label' ;

       Metadata.CustomMetadataValue customField1 = new Metadata.CustomMetadataValue();   
       customField1.field = 'Is_Admin_c__c';
       customField1.value = true;
       customMetadata.values.add(customField1);

       Metadata.CustomMetadataValue customField2 = new Metadata.CustomMetadataValue();  
       customField2.field = 'Profile_Full_Name_c__c' ;
       customField2.value = 'Admin';
       customMetadata.values.add(customField2);

       Metadata.CustomMetadataValue customField3 = new Metadata.CustomMetadataValue(); 
       customField3.field = 'Profile_Name_c__c' ;
       customField3.value = 'Admin';
       customMetadata.values.add(customField3); 

       Metadata.CustomMetadataValue customField4 = new Metadata.CustomMetadataValue(); 
       customField4.field = 'Updated_c__c' ;
       customField4.value = false;
       customMetadata.values.add(customField4);

       return customMetadata;
    }

}

Class Name-DeployCustomMetadata

public class DeployCustomMetadata {

    // Create metadata container 
    public Metadata.DeployContainer constructDeploymentRequest() {

        Metadata.DeployContainer container = new Metadata.DeployContainer();

        // Add components to container 
        Metadata.CustomMetadata cust = new createUpdateMetadata().createCustomMetadata();        

        container.addMetadata(cust);
        return container;
    }

    // Deploy metadata
    public void deploy(Metadata.DeployContainer container) {
        // Create callback. 
        PostInstallCallback callback = new PostInstallCallback();

        // Deploy the container with the new components. 
        Id asyncResultId = Metadata.Operations.enqueueDeployment(container, callback);
    }
}

Execute Anonymous Code

DeployCustomMetadata cc = new DeployCustomMetadata();
Metadata.DeployContainer container =cc.constructDeploymentRequest();
cc.deploy(container);
