Ruby on rails 未定义的方法“[]'；对于nil:NilClass在联系人表单上

这很奇怪。但是我的联系方式有问题。我已经实现了很多这样的表单，这与我的推理不符，为什么我在这一行为nil:NilClass获取

未定义的方法“[]”

<%= form_for(@inquiry, :html => {:"data-validate" => 'parsley'}) do |f| %>

以及模型

class Inquiry < ActiveRecord::Base
  # attr_accessible :title, :body
  extend ActiveModel::Naming
  include ActiveModel::Conversion
  include ActiveModel::Validations
  include ActionView::Helpers::TextHelper


  attr_accessor :name, :email, :phone_number, :message, :nickname, :subject, :check

  validates :name, presence: true

  validates :email, presence: true, format: { with: /\b[A-Z0-9._%a-z\-]+@(?:[A-Z0-9a-z\-]+\.)+[A-Za-z]{2,4}\z/ }

  validates :message, presence: true, length: { minimum: 10, maximum: 1000 }

  validates :nickname,  format: { with: /^$/ }

  validates :subject, presence: true, length: {maximum: 25}

  validates :check, presence: false

  def initialize(attributes = {})
    attributes.each do |name, value|
      send("#{name}=", value)
    end
  end

  def deliver
    ContactUs.contact_us(name, email, subject, message).deliver
  end

  def persisted?
    false
  end  
end

类查询
试试这个：-

<%= form_for @inquiry, :html => {:data-validate => 'parsley'} do |f| %>
OR
<%= form_for @inquiry, :html => {:"data-validate" => 'parsley'} do |f| %>

{:data validate=>'parsley'}do | f |%>
或
{：“数据验证”=>“欧芹”}do | f |%>
我通过更改解决了联系方式问题

<%= form_for(@inquiry, :html => {:"data-validate" => 'parsley'}) do |f| %>

{：“数据验证”=>“欧芹”}）do | f |%>

到

{：“数据验证”=>“欧芹”}do | f |%>

并将控制器更改为

class InquiriesController < ApplicationController

  def new
    @inquiry = Inquiry.new
  end

  def create
    @inquiry = Inquiry.new(params[:inquiry])

    if @inquiry.deliver
      flash[:notice] = "Your inquiry has been sent and we will be in touch as soon as possible. Thank you!"
      redirect_to action: :new
    else
      flash[:notice] = "Your inquiry has not been sent Thank you!"
      render :new
    end
  end

end

类查询控制器

非常感谢。
没有真正的帮助。问题在于与控制器和模型相关的
@inquiry
。只是好奇而已。为什么要
@inquiry.deliver
？不应该是
@inquiry.save
？失败时，您的参数设置为什么？看起来params[：inquiry]为空。@Pavan，deliver用于发送邮件。
<%= form_for(@inquiry, :html => {:"data-validate" => 'parsley'}) do |f| %>

<%= form_for :inquiry, url: inquiries_path, :html => {:"data-validate" => 'parsley'} do |f| %>

class InquiriesController < ApplicationController

  def new
    @inquiry = Inquiry.new
  end

  def create
    @inquiry = Inquiry.new(params[:inquiry])

    if @inquiry.deliver
      flash[:notice] = "Your inquiry has been sent and we will be in touch as soon as possible. Thank you!"
      redirect_to action: :new
    else
      flash[:notice] = "Your inquiry has not been sent Thank you!"
      render :new
    end
  end

end
