Rails API-无法将符号转换为整数

时间：2013-10-01 09:32:37

标签： ruby-on-rails api

我在rails应用程序上处理api测试时遇到此错误。

错误是; 

can't convert Symbol into Integer

app/controllers/api/v1/xml/messages_controller.rb:5:in `[]='
app/controllers/api/v1/xml/messages_controller.rb:5:in `create'

和

{"username"=>"info@skylinesms.com",
 "password"=>"[FILTERED]",
 "to"=>"256776582036",
 "from"=>"acacia",
 "message"=>"hello acacia",
 "format"=>:xml}

我怀疑问题是"format" => :xml参数。我如何阻止它被传入？

控制器是：

    def create
    @user = current_user
    @message = Message.new(params[:message])
    @message.user_id = current_user.id
    @message.status = 'Queued'
    if @message.save
        MessageWorker.perform_async(@message.id, lists, current_user.id)
        render json: {status: "success", to: @message.count, from: @message.from, 
                      balance: @user.balance, message: @message.message, 
                      time: @message.created_at} 
    else
        render status: 400 
    end
end

第5行是

@message = Message.new(params[:message])

回溯是

快速解决了这个问题

    def create
    @user = current_user
    @message = Message.new(params[:message])
    @message.message = params[:message][:text]
    @message.user_id = current_user.id
    @message.status = 'Queued'
    if @message.save
        MessageWorker.perform_async(@message.id, lists, current_user.id)
        render json: {status: "success", to: @message.count, from: @message.from, 
                      balance: @user.balance, message: @message.message, 
                      time: @message.created_at} 
    else
        render status: 400 
    end
end

现在收到此错误

undefined method `[]=' for nil:NilClass

答案 0 :(得分：2)

当您传递字符串时，无法创建消息，而不是散列。

您的params[:message]来电返回'hello acacia'，因此您实际致电第5行：

 @message = Message.new('hello acacia')

无效。

Message是一个ActiveRecord :: Model，因此它的初始化程序需要一个哈希值。
