Ich habe ein Zitat-Modell in meiner Rails-App, die verschiedene Attr-Typen hat, von denen einige von der DB gesendet/gespeichert werden, einige nicht und ich kann nicht verstehen, warum. Bitte kannst du mir helfen zu verstehen, danke.Warum einige Modellattribute nicht in der Datenbank gespeichert?
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 Modell
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.string "payment_frequency"
t.integer "commission_level"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.boolean "gla"
end

Ok Stack-Trace und @toddmetheny helfen mir, die fehlenden oder typo't zulässigen attrs zu sortieren. Jetzt nur noch die enums Quote.industries und Quote.payment_frequencies, deren Werte nicht gespeichert werden.
Ok, also Code geändert zu;
Und dies sendet die attrs aus der Form, aber sie immer noch in der db, Stack-Trace werden nicht erstellt:

So noch die params aren Da sie nicht in der DB gespeichert sind, sind sie erlaubt Params! irgendwelche Ideen?
Seltsam, eine psql select * from .. Abfrage zeigt, dass die Werte gespeichert wurden, aber Rails-Konsole; Quote.last.payment_frequency gibt null zurück ???
Aha, ich sehe, dass für eine Enumeration der Spaltentyp Integer sein sollte, aber es ist String in meinem Modell, könnte dies das Problem vielleicht sein?
Der Datentyp von enum'd attrs wurde in Integer geändert und alle verhalten sich wie erwartet.
