ruby-on-rails - Ruby on Rails 参数数量错误（给定 0 预期 1）

Question

您好，我正在尝试使用 Ruby on Rails 模型创建新记录，但是我收到了错误的参数错误。

错误信息：

配置/路由.rb

Rails.application.routes.draw do

mount RailsAdmin::Engine => '/admin', as: 'rails_admin' devise_for :modifications devise_for :users 资源 :user_steps 资源 :divorce_steps 资源 :divorces

root 'nav_pages#home'
get '/home', to:'nav_pages#home'
get '/wwd', to:'nav_pages#wwd'
get '/about', to:'nav_pages#about'
get '/contact', to:'nav_pages#contact'
get '/blog', to:'nav_pages#blog'
get '/are_you_married', to: 'qualifier#are_you_married'
get '/want_a_divorce', to: 'qualifier#want_a_divorce'

结尾

离婚控制器.rb：

class DivorcesController < ApplicationController

def new @divorce = Divorce.new 结束

def create @divorce = Divorce.new(user_params) @divorce.save end

私人的

def user_params
  params.require.(:divorce).permit(:marriage_date, :seperation_date, :state_of_mariage, :child_support, :address, :childrens_address, :contact_with_other, :telephone)
end

结尾

新的.html.erb

<div class = "container top-cont">

太好了，让我们开始约会吧！

<%= form_with(model: @divorce, local: true) 做 |f| %>

  <%= f.label :marriage_date %>
  <%= f.text_field :marriage_date, class: 'form-control' %>
  
  <%= f.label :seperation_date %>
  <%= f.text_field :seperation_date, class: 'form-control' %>
  
  <%= f.label :state_of_marriage %>
  <%= f.text_field :state_of_marriage, class: 'form-control' %>
  
  <%= f.label :child_support%>
  <%= f.text_field :child_support, class: 'form-control' %>
  
  
<%= f.label :child_support %>
  <%= f.text_field :child_support, class: 'form-control' %>
  
      <%= f.label :address %>
  <%= f.text_field :address, class: 'form-control' %>
  
      <%= f.label :childrens_address %>
  <%= f.text_field :childrens_address, class: 'form-control' %>
  
<%= f.label :contact_with_other %>
  <%= f.text_field :contact_with_other, class: 'form-control' %>
  
      <%= f.label :telephone %>
  <%= f.text_field :telephone, class: 'form-control' %>
  
  <%= f.submit "Create my account", class: "btn btn-primary" %>
<% end %>

非常感谢您的帮助，谢谢！

问题出在divorces_controller.rb

应该是params.require(:divorce)，不是params.require.(:divorce)
