更新了其他信息
我无法弄清楚如何解决这个问题。我尝试更新可卡因gem，重新启动服务器以及其他线程中描述的其他一些方法，但它们都没有工作。这是错误和下面的完整描述： MicropostsController中的ArgumentError #create 错误的参数个数（1表示0） app / controllers / microposts_controller.rb：6：在'create'
中Microposts Controller
class MicropostsController < ApplicationController
before_filter :signed_in_user
before_filter :correct_user, only: :destroy
def create
@micropost = current_user.microposts.build(params[:micropost])
if @micropost.save
flash[:success] = "Posted"
redirect_to root_path
else
@feed_items = []
render 'static_pages/home'
end
end
def destroy
@micropost.destroy
redirect_to root_path
end
private
def correct_user
@micropost = current_user.microposts.find_by_id(params[:id])
redirect_to root_path if @micropost.nil?
end
end
