Missing terms_accepted in user attributes about keycloak-extension-playground

[zalavaari]

Okay, my mistake. I've forgot to add the user.attributes prefix to my attributes.

Thanks for taking the time to get back to me.
The first part was the problem for me. I was missing the link between your comment about prefixing the attribute and the problem I was seeing.
Here's something close to what I did to get it working:

public void success(FormContext context) {
   MultivaluedMap<String, String> formData = context.getHttpRequest().getDecodedFormParameters();
   formData.add("user.attributes.my_terms_attr", String.valueOf(System.currentTimeMillis()));
   super.success(context);
}

This is the full code that is working for us:

package xxx;

import com.google.auto.service.AutoService;
import org.keycloak.authentication.FormActionFactory;
import org.keycloak.authentication.FormContext;
import org.keycloak.authentication.ValidationContext;

import org.keycloak.models.utils.FormMessage;
//import org.jboss.logging.Logger;

import javax.ws.rs.core.MultivaluedMap;
import java.util.List;
//import java.util.Map;

@AutoService(FormActionFactory.class)
public class CustomRegistrationUserCreation extends RegistrationUserCreation {
	//private static final Logger LOG = Logger.getLogger(CustomRegistrationUserCreation.class);

    public static final String ID = "xxx-registration-user-creation";

    public static final String TERMS_FIELD = "user.attributes.termsAccepted";
    public static final String TERMS_ACCEPTED_ATTRIBUTE = "user.attributes.termsLastChangeTimestamp";
    public static final String TERMS_IP_ADDRESS_ATTRIBUTE = "user.attributes.termsLastChangeIpAddress";
    public static final String TERMS_REQUIRED = "termsRequired";
    public static final String TERMS_REQUIRED_MESSAGE = "termsRequiredMessage";

    public static final String MARKETING_FIELD = "user.attributes.marketingAccepted";
    public static final String MARKETING_ACCEPTED_ATTRIBUTE = "user.attributes.marketingLastChangeTimestamp";
    public static final String MARKETING_IP_ADDRESS_ATTRIBUTE = "user.attributes.marketingLastChangeIpAddress";

    @Override
    public String getId() {
        return ID;
    }

    @Override
    public String getDisplayType() {
        return "Custom: Registration User Creation with Terms and Conditions";
    }

    @Override
    public void validate(ValidationContext context) {

        //MultivaluedMap<String, String> formData = context.getHttpRequest().getDecodedFormParameters();
        //LOG.debugf("\n\n\n\n\ntermsAccepted formData" + formData);
        //LOG.debugf("\n\n\n\n\ntermsAccepted field" + TERMS_FIELD);

//boolean termsAccepted = formData.containsKey(TERMS_FIELD);
        String termsAccepted = formData.getFirst(TERMS_FIELD);
        //String termsAccepted = formData.get(TERMS_FIELD);
        //LOG.debugf("\n\n\n\n\ntermsAccepted" + String.valueOf(termsAccepted));

        if (! termsAccepted.equals("1")) {
            context.error(Errors.INVALID_REGISTRATION);
            formData.remove(TERMS_FIELD);

            List<FormMessage> errors = List.of(new FormMessage(TERMS_FIELD, TERMS_REQUIRED_MESSAGE));
            context.validationError(formData, errors);
            return;
		} else {
			String termsTimestamp = String.valueOf(System.currentTimeMillis());
			//LOG.debugf("\n\n\n\n\ntermsAccepted" + String.valueOf(termsTimestamp));
            formData.add(TERMS_ACCEPTED_ATTRIBUTE, termsTimestamp);

			String termsIpAddress = context.getConnection().getRemoteAddr();
			//LOG.debugf("\n\n\n\n\ntermsAccepted" + String.valueOf(termsIpAddress));
            formData.add(TERMS_IP_ADDRESS_ATTRIBUTE, termsIpAddress);

			boolean marketingAccepted = formData.containsKey(MARKETING_FIELD);
			//LOG.debugf("\n\n\n\n\ntermsAccepted" + String.valueOf(marketingAccepted));

			String marketingTimestamp = String.valueOf(System.currentTimeMillis());
			//LOG.debugf("\n\n\n\n\ntermsAccepted" + String.valueOf(marketingTimestamp));
			formData.add(MARKETING_ACCEPTED_ATTRIBUTE, marketingTimestamp);

			String marketingIpAddress = context.getConnection().getRemoteAddr();
			//LOG.debugf("\n\n\n\n\ntermsAccepted" + String.valueOf(marketingIpAddress));
			formData.add(MARKETING_IP_ADDRESS_ATTRIBUTE, marketingIpAddress);
		}
        super.validate(context);
    }

    @Override
    public void buildPage(FormContext context, LoginFormsProvider form) {
        form.setAttribute(TERMS_REQUIRED, true);
    }
}

Same here. (with KeyCloak 16.1.1)

The code is wrong.

In the success function keycloak has already inserted data into database. If you add attribute to userModel there that attribute will never be saved into database.

I have changed the approch, i removed the success function and changed the validate function like:

    public void validate(ValidationContext context) {
        MultivaluedMap<String, String> formData = context.getHttpRequest().getDecodedFormParameters();
        // Now i use a radio instead of checkbox
        String termsAccepted = formData.getFirst(TERMS_FIELD);

        if (! termsAccepted.equals("1")) {
            context.error(Errors.INVALID_REGISTRATION);
            formData.remove(TERMS_FIELD);

            List<FormMessage> errors = List.of(new FormMessage(TERMS_FIELD, TERMS_REQUIRED_MESSAGE));
            context.validationError(formData, errors);
            return;
        } else {
	    String termsTimestamp = String.valueOf(System.currentTimeMillis());
            formData.add(TERMS_ACCEPTED_ATTRIBUTE, termsTimestamp);
	}
        super.validate(context);
    }

Thank you for sharing!

[zalavaari]

Hmm... are you sure formData.add(TERMS_ACCEPTED_ATTRIBUTE, termsTimestamp); is the correct line here?

[redbaron09]

Thanks for sharing!
I'm experiencing a similar issue with custom attributes not saving during registration.
However, I'm unable to get it working with the example validate function you've provided.
Can you provide a more complete example?

[zalavaari]

Hi!

Two things I learned here:

1. The custom atttibutes must begin with the user.attributes. prefix.
2. As @dvlpphb mentioned the current success(FormContext context) not works, but it can be fixed:

public void success(FormContext context) {
   MultivaluedMap<String, String> formData = context.getHttpRequest().getDecodedFormParameters();
   formData.add(TERMS_ACCEPTED_ATTRIBUTE, String.valueOf(System.currentTimeMillis()));
   super.success(context);
}
