Ruby on Rails 错误的参数数量（给定 0 期望 1）

Question

你好，我正在尝试在 Rails 模型上使用 Ruby 创建新记录，但是我遇到了错误的参数错误。

错误信息：

config/routes.rb

Rails.application.routes.draw do

mount RailsAdmin::Engine => '/admin'，如：'rails_admin' devise_for :修改 devise_for：用户资源：user_steps 资源：divorce_steps 资源：离婚

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'

结束

divorces_controller.rb:

class DivorcesController < ApplicationController

def 新 @离婚= Divorce.new 结束

定义创建 @divorce = Divorce.new(user_params) @divorce.save 结束

私人

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

结束

new.html.erb

<div class = "container top-cont">

太好了，让我们开始约会吧！

<%= form_with(模型：@divorce，本地：真)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 %>

非常感谢任何帮助谢谢！

Answer 1

问题出在divorces_controller.rb

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

Answer 2

试试：

params.require(:divorce)

实际上强参数使用语法：

params.require(:modal)
