|
||||
|
||||
## API Setup (For Mobile Apps)
|
||||
|
||||
### Step 1: Configure JWT Settings
|

2. **Add to DbContext** in `Infrastructure/Data/ApplicationDbContext.cs`
|
||||
3. **Create Migration**:
|
||||
```bash
|
||||
dotnet ef migrations add YourFeatureName --project src/PowderCoating.Infrastructure --startup-project src/PowderCoating.Web
|
||||
```
|
||||
4. **Update Database**:

||||
"AI": {
|
||||
"OpenAI": {
|
||||
"ApiKey": "sk-your-key-here",
|
||||
"Model": "gpt-4",
|
||||

|
||||
## Troubleshooting
|
||||
|
||||
### "Cannot connect to database"
|
||||
- Verify SQL Server is running
|
||||
- Check connection string is correct
|
||||
- Try connecting with SSMS first
|
||||
- Check Windows Firewall settings
|
||||
|
||||
### "The entity type 'X' requires a primary key to be defined"
|
||||
- Run migrations: `dotnet ef database update`
|
||||
- If persists, delete database and recreate
|
||||
|
||||
### "Port already in use"
|
||||
- Change ports in `Properties/launchSettings.json`
|
||||
- Or kill the process using the port
|
||||
|
||||

|
||||
dotnet restore --force
|
||||
dotnet clean
