This commit fixes two critical bugs in the trade system and adds a new
feature for automatic channel updates.
## Bug Fixes
### 1. Trade Channel Creation Permission Error (Discord API 50013)
**Issue**: Trade channels failed to create with "Missing Permissions" error
**Root Cause**: Bot was attempting to grant itself manage_channels and
manage_permissions in channel-specific overwrites. Discord prohibits bots
from self-granting elevated permissions in channel overwrites.
**Fix**: Removed manage_channels and manage_permissions from bot's
channel-specific overwrites in trade_channels.py. Server-level permissions
are sufficient for all channel management operations.
**Files Changed**:
- commands/transactions/trade_channels.py (lines 74-77)
### 2. TeamService Method Name AttributeError
**Issue**: Bot crashed with AttributeError when adding players to trades
**Root Cause**: Code called non-existent method team_service.get_team_by_id()
The correct method name is team_service.get_team()
**Fix**: Updated method call in trade_builder.py and all test mocks
**Files Changed**:
- services/trade_builder.py (line 201)
- tests/test_services_trade_builder.py (all test mocks)
## New Features
### Smart Trade Channel Updates
**Feature**: When trade commands are executed outside the dedicated trade
channel, the trade embed is automatically posted to the trade channel
(non-ephemeral) for visibility to all participants.
**Behavior**:
- Commands in trade channel: Only ephemeral response to user
- Commands outside trade channel: Ephemeral response + public post to channel
- Applies to: /trade add-team, /trade add-player, /trade supplementary, /trade view
**Implementation**:
- Added _get_trade_channel() helper method
- Added _is_in_trade_channel() helper method
- Added _post_to_trade_channel() helper method
- Updated 4 trade commands to use smart posting logic
**Files Changed**:
- commands/transactions/trade.py (new helper methods + 4 command updates)
## Documentation Updates
Updated comprehensive documentation for:
- Trade channel permission requirements and troubleshooting
- TeamService correct method names with examples
- Smart channel update feature and behavior
- Bug fix details and prevention strategies
**Files Changed**:
- commands/transactions/README.md
- services/README.md
## Testing
- All 18 trade builder tests pass
- Updated test assertions to match new error message format
