我想更新帖子(方坯),我发现此错误:Unpermitted parameters: contenu, type_de_billet
class BilletsController < ApplicationController
def billet_params
params.require(:billet).permit(:title, :contenu, :user_id, :type_de_billet, :image)
end
end
所以parameters: contenu, type_de_billet
已经允许&#39;
这是一个日志

我不得不说我有一个名为Photo

def edit
render layout: "amabiblio_blog"

@billet = current_user.billets.build(billet_params)

if params[:images]
params[:images].each { |image|

答案 0 :(得分:4)
您在update
方法中有下一行:
if @billet.update(params[:billet].permit(:title,:description))
您应该更改为create
中的相同内容:
if @billet.update(billet_params)
现在,您仅在contenu, type_de_billet
操作中使用允许的参数create
。
