语法错误，意外的keyword_end，期望')‘结束

Question

我正在打开一个API，当没有返回时，它抛出了一个“NoMethodfornilClass”错误。因此，我添加了一组if/else语句来处理这个问题。下面是我的密码。

现在我收到了一个错误：

syntax error, unexpected keyword_end, expecting ')' end

因为它起作用了，我觉得我的路线很好。我在下面的视图中标记了导致错误的行。当我删除那个end时，它仍然会抛出错误：

main_controller.rb

def money
    @first = params[:first_name]
    @last = params[:last_name]
    @politician = JSON.load(open("http://..."))
        if @politician.empty?
            @politician = "Enter a politician's name."
        else
            @year = params[:year]
            @pol_id = @politician[0]["id"]
            @breakdown = JSON.load(open("http://..."))
                if (@breakdown["Individuals"]).nil? 
                    @individuals_money = 0
                    @individuals = 0
                else 
                    @individuals_money = (@breakdown["Individuals"][1]).to_f 
                    @individuals = @breakdown["Individuals"][0]
                end
                if (@breakdown["PACs"]).nil?
                    @pacs_money = 0
                    @pacs = 0
                else
                    @pacs_money = (@breakdown["PACs"][1]).to_f
                    @pacs = @breakdown["PACs"][0]
                end
            @total_money = @individuals_money + @pacs_money
            @top_contributors = JSON.load(open("http://..."))
     end
   end

Answer 1

我想我看到了这行的语法错误：<p><%= number_to_currency(@pacs_money + " from " + @pacs + " PACs" %></p>

对于number_to_currency，没有结束括号。它应该是：

<p><%= number_to_currency(@pacs_money) + " from " + @pacs + " PACs" %></p>
