我是Rails的新手，一直遇到这个错误。我已经仔细检查了我的语法，一切似乎都很好。我已经包括了我认为是相关的文件，但让我知道，如果你需要更多的信息。
controllers/users_controller.rb：

class UsersController < ApplicationController

def index
    @users = User.all
    render json: @users, status: :ok
end

def show
    render json: @user
end

def create

    @user = User.new(user_params)
    @user.save
    render json: @user, status: :created
end

def update
    if @user.update(user_params)
      render json: @user
    else
      render json: @user.errors, status: :unprocessable_entity
    end
end

def destroy
    @user = User.where(id: params[:id]).first
    if @user.destroy
        head(:ok)
    else
        head(:unprocessable_entity)
    end
end

private 

def set_user
    @user = User.find(params[:id])
end

def user_params
params.require(:user).permit(:name, :email, :password)
