Lightning: Create a URL button in case object which opens up custom object create new page with pre-populated values from case

Question

We are migrating our code to lightning. We have a javascript button in case object which opens up a custom object create new record page with pre-populated values from case. How can i do the same thing in lightning?.

We tried multiple ways but the values are not getting populated. The custom object got 2 lookup fields for case and contact. Which i need to pre-populate.

srcUp('/{!$Setup.customSetting.Prefix__c}/e?{!$Setup.customSetting.Case_Field__c}={!Case.CaseNumber}&{!$Setup.customSetting.Case_Field__c}_lkid={!Case.Id}&{!$Setup.customSetting.Contact_Field__c}={!Contact.Name}&{!$Setup.customSetting.Contact_Field__c}_lkid={!Contact.Id}') 

field IDs we have saved in the custom setting in the above.

You would typically create a Quick Action that calls a controller method, which in turn fires off a force:createRecord event. The example in the documentation provides the necessary code:

var createAcountContactEvent = $A.get("e.force:createRecord");
createAcountContactEvent.setParams({
    "entityApiName": "Contact",
    "defaultFieldValues": {
        'Phone' : '415-240-6590',
        'AccountId' : '001xxxxxxxxxxxxxxx'
    }
});
createAcountContactEvent.fire();

All you need to do is create a new component that serves as a Quick Action to initialize your component, then fire off this event. The platform will take care of the rest for you.

Note that you can now use the standard API names, instead of maintaining custom settings that keep track of the field ID. You may need to combine this with force:recordData in order to bring in current record information.

There's other (recent) examples of this if you just search for the term here on the Salesforce StackExchange.
