Channels

One-way broadcast channels: create, subscribe, publish posts.

Data models (app/models.py)

• Chat — for channels chat_type='channel', with id, title, description, avatar, created_by, is_verified, created_at, subscribers_count.
• ChannelMember — id, channel_id, user_id, role (‘owner’ | ‘admin’ | ‘subscriber’), joined_at.
• ChannelBind — id, channel_id, group_id, created_at (links a discussion group).
• Posts reuse the Message model with chat_id pointing at the channel.

Endpoints (app/routes/spav2/channels.py)

All under V2 + '/api' → /api.v2/api/channels/...:

• POST /api/api/channels/create — create a channel (title, description, avatar).
• GET /api/api/channels/info — channel metadata + subscriber count.
• GET /api/api/channels/subscribers — list subscribers.
• POST /api/api/channels/subscribe / POST /api/api/channels/unsubscribe — toggle membership.
• POST /api/api/channels/set-title / POST /api/api/channels/set-avatar — update metadata.
• POST /api/api/channels/verify — mark channel verified (admin only).
• Publishing posts goes through messages/send with the channel chat_id.

Frontend module (static/js/k/)

• channels.js — channel browsing, subscribe buttons, post composition.

Notes

• ChannelMember.role distinguishes owner/admin from plain subscriber.
• Only owner/admin can publish; messages/send checks the sender’s role in the channel.
• Verification is restricted to @admin_required.
