[英]Ruby on Rails Wrong Number of arguments (given 0 expected 1)
你好,我正在嘗試使用 Ruby on Rails 模型創建一個新記錄,但是我收到了一個錯誤的參數錯誤。
錯誤信息:
配置/路由.rb
Rails.application.routes.draw do
mount RailsAdmin::Engine => '/admin', as: 'rails_admin' devise_for :modifications devise_for :users resources :user_steps resources :divorce_steps resources :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'
結尾
離婚_controller.rb:
class DivorcesController < ApplicationController
def new @divorce = Divorce.new end
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
結尾
新的.html.erb
<div class = "container top-cont">
讓我們開始約會吧!
<%= form_with(model: @divorce, local: true) do |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 %>
非常感謝您的任何幫助!
問題在於divorces_controller.rb
它應該是params.require(:divorce)
,而不是params.require.(:divorce)
嘗試:
params.require(:divorce)
實際上強參數使用語法:
params.require(:modal)
