我试图根据数据库中的集合返回一组单选按钮,但我没有多少运气。集合中的单选按钮

查看代码

- @merchant_type.each do |mt| 
    = form.radio_button mt, mt.name 

控制器代码

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 

错误

ActionView::Template::Error (undefined method `#<MerchantType:0x007fd16b55ac50>' for #<Merchant:0x007fd16c481468>): 
    6:  p 
    7:  b Type 
    8:  - @merchant_type.each do |mt| 
    9:   = form.radio_button mt, mt.name 
    app/views/admin/merchants/_type.html.slim:9:in `block in _app_views_admin_merchants__type_html_slim___3402008222164699688_70268702644260'

'MerchantType.all'显然是触发了错误......但我无法推断出可能触发错误的原因。我假设你能够在你的滑轨控制台中运行'MerchantType.all'吗? – angkiki

你试过这个“form.radio_button:merchant_type,mt.name”吗? – Jayaprakash

@Jayaprakash不,我没有,似乎已经工作 –

试试这个

- @merchant_type.each do |mt| 
    = form.radio_button :merchant_type, mt.name
