我的应用程序上有评论家和电影，我正在添加crtics功能，以便将电影添加到他们的收藏夹中。 现在，添加或删除都不起作用。 在尝试添加时，它会尝试发布补丁请求而不是帖子。 当试图删除时，它无法使用delete方法，因为我认为它没有找到要删除的对象。 不知道为什么会这样。 我将在下面添加所有代码和一些服务器日志。 真的需要一些帮助来解决这个问题。

更新：我刚刚在控制台中测试了最喜欢和不喜欢的方法，它们都有效; 然而，一些奇怪的事情正在发生，其中id似乎没有增加一个而是一个看似随机的数字。
I have Critics and Movies on my app and I am adding the function for crtics to add movies to their favorites. Neither add nor remove is working right now. When trying to add, it's trying to issue a patch request rather than a post. When trying to remove, it's not able to use the delete method, because I don't think it's finding the object to delete. Not sure why this is happening. I'll add all code and some server logs below. Really need some help going over this.

If any other code will be helpful let me know.
UPDATE: I just tested both the favorite and un_favorite methods in the console, and they both work; however something odd is happening where the id's don't seem to be incrementing by one but instead by a seemingly random number.
最满意答案
出现第一个RoutingError是因为您在视图中使用current_critic.favorites.create ，它返回一个已经有id的记录，因此form_for会将其解析为update而不是create 。=>解决方案：用current_critic.favorites.new替换
发生第二个RecordNotFound是因为您传递了Favorite的ID但用于查找Movie=>解决方案：
def destroy favorite = current_critic.favorites.find(params[:id]) favorite.destroy redirect_to current_critic end The first RoutingError occurs because you use current_critic.favorites.create in your view, which returns a record already had an id, so the form_for will resolve it to update rather than create.=> Solution: replace with current_critic.favorites.new
The second RecordNotFound occurs because you pass an id of Favorite but used to find a Movie=> Solution:
def destroy favorite = current_critic.favorites.find(params[:id]) favorite.destroy redirect_to current_critic end更多推荐
