Sida loo isticmaalo nidaamka Poll Voting

The voting logic enforces:

Only one vote per user per poll
Creators cannot vote on their own polls
Haku waxay ku salaysan tababarka dhismaha
Results are displayed and updated in real time

Sida loo isticmaali karaa in ay loo isticmaali karaaViewPoll.tsxHaku:

Fetch the Logged-In UserWe need the current user’s ID to determine voting eligibility and record their vote.

import { createClient } from "@/utils/supabase/component";
import { User } from "@supabase/supabase-js";

const ViewPoll = () => {
  const [user, setUser] = useState<User | null>(null);

  const supabase = createClient();

        data: { user },
      } = await supabase.auth.getUser();
      setUser(user);
    };

    fetchUser();
  }, []);

Load Poll Details and Check Voting StatusOnce we have the user, we fetch:

Qalabka dhismaha (ka mid ka mid ka mid ka mid ka mid ka mid ka mid ka mid ah)
Whether this user has already voted

Waxaan sidoo kale soo xiriir in uu ku saabsan updates real-time.

        .single();

      setPoll(data);
      setPollLoading(false);

      checkUserVote();
    };

    fetchPoll();

Listen for Real-Time Updates

Waayo, waxaan ka soo bandhigay in ay ka mid ah wax soo saarka.votes table, scoped to this poll. When a new vote is cast, we fetch updated poll data and voting status.

        () => {
          fetchPoll();
          checkUserVote();

      )
      .subscribe();

    return () => {
      supabase.removeChannel(channel);
    };
  }, [query.id, user]);

Handle the Vote Submission

If user has not voted and is allowed to vote (we’ll add a permission check later), we’ll insert his vote.

  const handleVote = async (optionId: string) => {
    if (!user) return;

    try {
      const { error } = await supabase.from("votes").insert({

      if (!error) {

Assigning per-resource roles (like “creator” for a specific poll)

Waayo, waxaa loo yaqaan 'Relationship-based permissions', waxaan u isticmaali karaa ReBAC iyo Permit.io.

ReBAC (Relationship-Based Access Control) waa mid ka mid ah

In this tutorial, we apply ReBAC to a polling app:

A user who created a poll is the only one who can manage (edit/delete) it
Waxaa la heli karaa in la soo bandhigiisa.
Muuqaalka macaamiisha waxaa laga heli karaa 1 toddobaad per poll

By modeling these relationships in Permit.io, we can define fine-grained access rules that go beyond Supabase’s built-in Row Level Security (RLS). We’ll enforce them at runtime using Supabase Edge Functions and Permit’s policy engine.
