在我的应用中，我有users和board_games。每个对象都有多个对象，因此我制作了一个称为user_board_games的：through表，可以在其中存储board_game_id和user_id，以便用户可以建立自己拥有的棋盘游戏库。
我有前往user_board_games的路线，如下所示：
Rails.application.routes.draw do
mount_devise_token_auth_for "User", at: "api/auth"
namespace :api do
resources :board_games do
resources :game_sessions
resources :users
end
resources :users do
resources :board_games
resources :friends
put '/get_board_games', to: 'board_games#get_board_games'
end
end
get "*other", to: "static#index"
end
（看跌期权是一种可能的解决方案，我将在稍后提到）。
我的axios呼叫看起来像这样：
componentDidMount() {
const userId = this.props.user.id
axios.get('/api/board_games')
.then(res => {
console.log(res.data)
this.setState({games: res.data});
})
axios.get(`/api/users/${userId}/board_games/`)
.then(res => {
console.log(res.data);
this.setState({user_games: res.data});
} )
}
由于某些原因，这些调用都在我的board_games控制器中命中了我的index方法。 console.log提供的棋盘游戏数组与所有棋盘游戏都在用户库中相同，但是我没有在用户库中添加任何棋盘游戏，因此第二个数组应为空。
我的friends表也存在此问题，该表仅属于该用户，并保留其他用户的名称或ID的字符串。当我通过表单将朋友添加到一个用户，然后切换用户和axios.get朋友时，它的作用就像所有朋友都属于所有用户并在user2下显示user1的朋友。
当我检查sqlectron来查看user_board_games中没有什么时，什么都没有，因此它并不是将所有board_games实际添加到该表中，它只是对board_games进行了两次索引，而与路径无关。
昨晚，有人在帮助我，并建议在我的board_games控制器中创建另一个方法，该方法告诉它在获取user_id时应如何处理，以便在正确的表中进行发布和获取。
感谢您提供的任何帮助。让我知道是否需要查看更多代码以提供帮助。
