我有兩個模型,一個是customer.rb,第二個是money.rb。 關係是客戶has_many:金錢belongs_to客戶。我正在使用MySql遠程數據庫。當我嘗試在同一時間,它只是正常工作來提取單個表中的數據,但問題是,當我嘗試這樣做:Ruby on Rails ActiveRecord :: StatementInvalid在客戶中#show
<%= @customer.money.each do |m| %>
<%= m.id %>
<%= m.cid %>
<% end %>
它拋出一個錯誤的:mysql ::錯誤:未知列「money_tb。 customer_id'in'where clause':SELECT money_tb
。* FROM money_tb
where money_tb
。 customer_id
=? 這裏是我的show.html.erb的一個片段:
<h1><%= @customer.name %></h1>
<%= @customer.money.each do |m| %>
<%= @m.id %>
<%= @m.cid %>
<%= @m.customer.name %>
<% end %>
這裏是我的customers_controller:
class CustomersController < ApplicationController
def index
@customers = Customer.all
end
def new
@customer = Customer.new
end
def create
@customer = Customer.new(customer_params)
if @customer.save
flash[:notice] = "Customer Create"
redirect_to new_customer_path
else
render 'new'
end
end
def edit
@customer = Customer.find(params[:id])
end
def update
@customer = Customer.find(params[:id])
if @customer.update(customer_params)
flash[:notice] = "Customer Updated"
redirect_to customers_path
else
render 'edit'
end
end
def show
@customer = Customer.find(params[:id])
end
private
def customer_params
params.require(:customer).permit(:name, :address, :ph_no)
end
end
這是模型:
class Customer < ActiveRecord::Base
self.table_name = "cust_tb"
has_many :money
has_many :gold
end
我也想提一下貨幣表中的customer_id字段表示爲「cid」
非常感謝#Michal_Mlozinak。它的工作,謝謝你.... –
