Usage Example
class GreenhousesViewModel(
private val greenhousesRepository: GreenhousesRepository
) : ViewModel() {
private val _greenhouses = MutableStateFlow<List<Greenhouse>>(emptyList())
val greenhouses: StateFlow<List<Greenhouse>> = _greenhouses.asStateFlow()
private val _error = MutableStateFlow<String?>(null)
val error: StateFlow<String?> = _error.asStateFlow()
fun loadGreenhouses(tenantId: Long) {
viewModelScope.launch {
greenhousesRepository.getGreenhousesByTenantId(tenantId)
.onSuccess { _greenhouses.value = it }
.onFailure { _error.value = it.message }
}
}
fun createGreenhouse(
tenantId: Long,
name: String,
location: Location?,
areaM2: Double?
) {
viewModelScope.launch {
greenhousesRepository.createGreenhouse(
tenantId = tenantId,
name = name,
location = location,
areaM2 = areaM2,
timezone = "Europe/Madrid",
isActive = true
)
.onSuccess { loadGreenhouses(tenantId) }
.onFailure { _error.value = it.message }
}
}
fun updateGreenhouse(
tenantId: Long,
greenhouseId: Long,
name: String? = null,
isActive: Boolean? = null
) {
viewModelScope.launch {
greenhousesRepository.updateGreenhouse(
tenantId = tenantId,
greenhouseId = greenhouseId,
name = name,
isActive = isActive
)
.onSuccess { loadGreenhouses(tenantId) }
.onFailure { _error.value = it.message }
}
}
}
Dependency Injection
Inject the repository using Koin in your Composables:
import org.koin.compose.viewmodel.koinViewModel
@Composable
fun GreenhousesScreen(tenantId: Long) {
val viewModel: GreenhousesViewModel = koinViewModel()
val greenhouses by viewModel.greenhouses.collectAsState()
LaunchedEffect(tenantId) {
viewModel.loadGreenhouses(tenantId)
}
// UI implementation
}
