基本上，我想在app/database/migrations文件夹中放置两个不同的文件夹，只从其中一个加载迁移
- migrations
- folder 1
- folder 2
当我运行php artisan migrate时，我希望它查看我的config/app.php并确定需要执行哪些文件。有可能吗？

是的，您可以从特定文件夹迁移。只需在运行迁移时添加 --path 。
喜欢：php artisan migrate --path='database/migrations/folder1'

不确定我们是否可以使用您的 Laravel 版本 (5.1)，从 5.3 Laravel 开始支持 // here's the function that decreases playerEnergy, which is triggered by a button
// Game.tsx
const [playerEnergy, setPlayerEnergy] = useAtom(playerEnergyAtom);
const decreaseEnergy = () => {
setPlayerEnergy(playerEnergy <= 0 ? 0 : playerEnergy - 10);
};
// then I watch playerEnergy and set the an event state to NO_ENERGY if it is 0
// EnergyLevel.tsx
const [, setEventTriggeredOfType] = useAtom(eventTriggeredOfTypeAtom);
useEffect(() => {
if (playerEnergy <= 0) setEventTriggeredOfType(EventType.NO_ENERGY);
}, [playerEnergy, setEventTriggeredOfType]);
// here is the EndGame component that is only rendered when
// shouldTriggerEndGame returns true
// Game.tsx
const [shouldTriggerEndGame] = useAtom(shouldTriggerEndGameAction);
if (shouldTriggerEndGame) return <EndGame />;
// here is the shouldTriggerEndGame atom that checks the event state
// gameActions.ts (this file holds all the atoms)
export const shouldTriggerEndGameAction = atom((get) => {
// this is what returns stale atom value SOMETIMES
const eventTriggeredOfType = get(eventTriggeredOfTypeAtom);
return [
eventTriggeredOfType === EventType.NO_ENERGY
].some((triggerState: boolean): boolean => triggerState === true);
});
// here is the "Start Over" button handler that resets the EventType above:
// EndGame.tsx
const goBackToMainMenu = () => {
setEventTriggeredOfType(EventType.NONE);
// triggers a return to the main screen (always works)
setActiveScreen(Screen.NONE);
};
// these are triggered by UI buttons from the user
// gameActions.ts
export const startNewGameAction = atom(null, (_get, set) => {
set(resetDefaultGameState, null);
set(isLoadingGameOfTypeAtom, LoadType.NEW);
});
export const loadLastGameAction = atom(null, (_get, set) => {
set(resetDefaultGameState, null);
set(isLoadingGameOfTypeAtom, LoadType.SAVED);
});
// isLoadingGameOfType is being watched from within <Game />
// Game.tsx
const loadSavedGameRef = useRef(loadSavedGame);
const createNewGameRef = useRef(createNewGame);
useEffect(() => {
if (isLoadingGameOfType === LoadType.SAVED) loadSavedGameRef.current();
if (isLoadingGameOfType === LoadType.NEW) createNewGameRef.current();
}, [isLoadingGameOfType]);
// these are triggered by <Game />'s useEffects when the appropriate
// eventTriggeredOfType values are true
// gameActions.ts
export const loadSavedGameAction = atom(null, async (get, set) => {
const playerData = get(playerDataAtom);
set(playerEnergyAtom, playerData.lastGameState.playerEnergy);
});
export const createNewGameAction = atom(null, (_get, set) => {
set(playerEnergyAtom, 100);
});
方法。
通过向 loadMigrationsFrom 类的 boot 方法添加以下行，我注册了自定义迁移路径以放置所有触发器定义。
