未定义局部变量或方法`availability_params‘用于#<AvailabilitiesController>

Question

我试图在程序中创建新的可用性对象，突然之间我就找不到availabilities_params了。不知道到底是怎么回事。

class AvailabilitiesController < ApplicationController

def create
    @availability = Availability.new(availability_params)
    @availability.save

    if member_signed_in?
      redirect_to member_path(current_member)
    elsif provider_signed_in?
      redirect_to provider_path(current_provider)
    end

end

def new
    @availability = Availability.new
end

def show
    @availability
end

private

def availabilty_params
    params.require(:availability).permit(:time, :date, :provider_id, :user_id)
end


end

下面是创建可用性的表单

= form_for(@availability) do |f|
   =    f.date_field :date, :min=> "2014-11-00", :value => "2015-01-01"
   = f.time_field :time, :placeholder => "Available Time"
   -if member_signed_in?
     = f.hidden_field :member_id, value: current_member.id
   -elsif provider_signed_in?
     = f.hidden_field :provider_id, value: current_provider.id
= f.submit

Answer 1

方法名中有一个错误。它应该是def availability_params而不是def availabilty_params。

Answer 2

在你的创造行动中，你有

 @availability = Availability.new(availability_params)

在您的availability_params方法中，您有以下内容

def availabilty_params
    params.require(:availability).permit(:time, :date, :provider_id, :user_id)
end

请将availabilty_params更改为availability_params
