我的rails应用程序中有一个Quote模型,它有各种attr类型,其中一些是由db发送/保存的,有些不是,我无法理解为什么。请帮助我理解,谢谢。
quotes_controller.rb
class QuotesController < ApplicationController
def create
@quote = Quote.new(quote_params)
if @quote.save
redirect_to root_url, notice: 'Quote request created'
else
render :new
end
end
private
def quote_params
params.require(:quote).permit(:gla, :prev_cover, :co_name, :postcode, :industry, :lives_overseas,
:scheme_start_date, :payment_frequency, :commision_level)
end
end
quote.rb模型
class Quote < ApplicationRecord
validates :gla, presence: { message: "Must be selected" }
enum industry: [ :financial_services, :architect, :business_consultancy ]
enum payment_frequency: [ :annually, :monthly ]
end
schema.rb
create_table "quotes", force: :cascade do |t|
t.boolean "prev_cover"
t.string "co_name"
t.integer "co_number"
t.string "postcode"
t.string "industry"
t.boolean "lives_overseas"
t.date "scheme_start_date"
t.string "payment_frequency"
t.integer "commission_level"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.boolean "gla"
end
rails console:
Pry> Quote.last.attributes
Quote Load (0.4ms) SELECT "quotes".* FROM "quotes" ORDER BY "quotes"."id" DESC LIMIT $1 [["LIMIT", 1]]

好的堆栈跟踪和@toddmetheny帮助我理清丢失或错字的允许的attrs。现在只是枚举Quote.industries
和Quote.payment_frequencies
,其值不会被保存。
好的,所以代码改为;
这会从表单中发送attrs,但它们仍然没有在db,stack trace中创建:

所以仍然没有在数据库中保留params,它们被允许使用params!任何想法?
奇怪的是,psql select * from ..
查询显示值已保存,但是Rails控制台; Quote.last.payment_frequency
返回nil ???
啊哈,我看到对于枚举,列类型应该是整数,但它在我的模型中是字符串,这可能是问题吗?
enum'd attrs的数据类型更改为整数,并且所有数据类型都按预期运行。
答案 0 :(得分:1)
发布堆栈跟踪。 scope: true
未在允许的参数中列入白名单。这至少是该特定领域问题的一部分。其他人是...但是在日志中发布您实际看到的内容,以便我们可以看到通过表单传递的内容。堆栈跟踪中还会有消息,为您提供有关这些值未保存的原因的线索。
更新:堆栈跟踪列出了2个未经许可的参数:co_number
和co_number
(您有错误允许佣金级别且co_number不存在)
有些东西也有空白值......比如commission_level
和payment_frequency
......我会深入研究为什么这些东西不应该是空白的。表格是否具有这些东西的价值?他们没有被通过。这似乎可以解释其余的零值。
