package org.casbin.adapter;

import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoClients;
import com.mongodb.client.MongoDatabase;
import org.casbin.jcasbin.main.Enforcer;
import org.casbin.jcasbin.persist.Adapter;
import org.jim.jcasbin.MongoAdapter;

import java.util.ArrayList;

public class Test {
    public static void main(String[] args) {
        // Use MongoDB connection string and database name to initialize a MongoAdapter.
        String connectionString = "mongodb://localhost:27017/";
        MongoClient mongoClient = MongoClients.create(connectionString);
        MongoDatabase database = mongoClient.getDatabase("casbin");

        // Check and create a collection
        if (!database.listCollectionNames().into(new ArrayList<>()).contains("casbin_rule")) {
            database.createCollection("casbin_rule");
        }

        Adapter adapter = new MongoAdapter(mongoClient, "casbin");
        Enforcer enforcer = new Enforcer("examples/rbac_model.conf", "examples/rbac_policy.csv");

        // Check the permission.
        enforcer.enforce("alice", "data1", "read");

        // Modify the policy.
        // enforcer.addPolicy(...);
        // enforcer.removePolicy(...);

        // Save the policy back to DB.
        adapter.savePolicy(enforcer.getModel());

        // Close the MongoDB client.
