ruby-on-rails - 强参数赋值：查询 params.require

Question

我有以下代码行，但不知道为什么我收到错误“ActionController::ParameterMissing in LeaguesController#create param not found:league_name”：

class LeaguesController < ApplicationController
  def new
    @league = League.new
  end

  def create
    @league = League.new(league_params)
    if @league.save
        redirect_to payments_new_url
    else
        render 'new'
    end
  end

  private

  def league_params
    params.require(:league_name).permit(:league_url)
  end
end

Answer 1

尝试要求league，因为它是对象，并允许 _name 和 _url

params.require(:league).permit(:league_url, :league_name)
