我試圖根據數據庫中的集合返回一組單選按鈕,但我沒有多少運氣。集合中的單選按鈕
查看代碼
- @merchant_type.each do |mt|
= form.radio_button mt, mt.name
控制器代碼
def new
@merchant_type = MerchantType.all
@merchant = Merchant.new
@states = State.form_selector
@products = Product.order(:name => 'asc')
@properties = Property.where(property_set_id: 1)
@merchant.trading_hours.build
end
錯誤

'MerchantType.all'顯然是觸發了錯誤......但我無法推斷出可能觸發錯誤的原因。我假設你能夠在你的滑軌控制檯中運行'MerchantType.all'嗎? – angkiki
你試過這個「form.radio_button:merchant_type,mt.name」嗎? – Jayaprakash
@Jayaprakash不,我沒有,似乎已經工作 –
