Question

有两个问题。

首先，我想启用一个成功更新的操作。现在我不知道为什么我无法成功更新。

其次，我想编辑和更新现有记录的列，我发现如果我做一个动作获取并对应一个充当put动作的动作，则get动作被识别为编辑的存在，我不希望这样，所以我该如何解决？

查看split_now.html.erb

<div class="container">
 <h1>Split</h1>
 <%= form_for @currency, url: { action: 'split', controller: 'currencies'}, method: :put do |f|%>
  <% if @currency.errors.any? %>
      <div id="error_explanation" class="alert alert-danger">
        <h2><%= @currency.errors.count %>error(s) exist(s).</h2>
        <ul>
          <% @currency.errors.full_messages.each do |msg| %>
              <li><%= msg %></li>
          <% end %>
        </ul>
      </div>
  <% end %>
  <p>amount whatever you want to issue like 100</p>
  <div class="input-group">
    <%= f.number_field :amount,:class=>'form-control form-group',placeholder:"amount",min:"1",step:"1",required:true%>
  </div>
  <%= f.submit 'done', class: "btn btn-large bg-info" %>
 <% end %>
</div>

currencies_contoroller.rb

def split_now
  @currency=Currency.find_by_slug(params[:id])
end


def split
   @currency=Currency.find_by_slug(params[:id])
  if CurrencyUser.where(currency_id:@currency.id,owner:true).first.user==current_user
    issue_more(params,@currency)
  else
    redirect_to @currency,alert:"This currency wasn't issued by you"
  end
end

def issue_more(params,currency)
   result=false
   current_amount=currency.amount
  result=currency.increment("amount",params[:amount].to_i)
 currency_user=CurrencyUser.find_by(currency_id:currency.id,owner:true)
 currency_user.increment("amount",params[:amount].to_i)
 return result
end`

路由

 resources :currencies do
  member do
    put :split
    get :split_now
  end
 end

我无法更新现有记录，我希望操作不要像编辑操作那样
