Dynamic Rails的强大参数 [英] Dynamic Strong params for require - Rails

问题描述

我现在有一个更新方法，不适用于所有情况。在这个强有力的参数中，这个硬编码就像这样 params.require（：integration_webhook）.permit（：filters），现在都很好，但有时可能是 integration_webhook ，其他时候它需要是 integration_slack 。基本上，有没有办法，我不需要在强大的参数中硬编码需求？

更新方法：

  def update 
 @integration = current_account.integrations.find（params [：id]）
 
 attrs = params.require（：integration_webhook）.permit（：filters）
 
 if @ integration.update_attributes（attrs）
 flash [：success] =已添加过滤器
 redirect_to account_integrations_path 
 else 
呈现：过滤器
 end 
 end 
  

您可以看到它是一种标准的更新方法。但是我需要integration_webhook参数是动态的。我想知道是否有一个模型方法，我可以调用去除integration_webhook部分？

解决方案

不完全确定如何动态这需要是，但假设我们要么得到一个 integratino_webhook 或一个 integration_slack 。

  def update 
 @integration = current_account.integrations.find（params [：id]）
 
 if @integration .update_attributes（update_params）
＃... 
 else 
＃... 
 end 
 end 
 
 private 
 def update_params 
 params.require（：integration_webhook）.permit（：filters）if params.has_key？（：integration_webhook）
 params.require（：integration_slack）.permit（：filters）if params.has_key？ ：integration_slack）
 end 
  

结帐强参数需要多个，如果这没有回答哟您的问题。

修改

更多动态需求：

  def update_params 
 [：integration_webhook，，integration_slack] .each do | model | 
 return params.require（model）.permit（：filters）if params.has_key？（model）
 end 
 end 
  

I have an update method right now that will not work for all situations. It is hard coded in the strong params like this params.require(:integration_webhook).permit(:filters) that all fine right now but sometimes it may be integration_webhook and other times it needs to be integration_slack. Basically, is there a way that I don't need to hardcode the require in the strong params? I'll show my code for clarity.

Update Method:

    def update
     @integration = current_account.integrations.find(params[:id])

     attrs = params.require(:integration_webhook).permit(:filters)

     if @integration.update_attributes(attrs)
      flash[:success] = "Filters added"
      redirect_to account_integrations_path
     else
      render :filters
     end
   end

As you can see it's a standard update method. But I need the integration_webhook params to be dynamic. I'm wondering if there is a model method I could call to strip away the integration_webhook part?

解决方案

Not totally sure how dynamic this needs to be, but assuming that we are either getting an integratino_webhook or a integration_slack.

def update
  @integration = current_account.integrations.find(params[:id])

  if @integration.update_attributes(update_params)
    # ...
  else
    # ...
  end
end

private
  def update_params
    params.require(:integration_webhook).permit(:filters) if params.has_key?(:integration_webhook)
    params.require(:integration_slack).permit(:filters) if params.has_key?(:integration_slack)
  end

Checkout Strong parameters require multiple if this didn't answer your question.

Edit

For more dynamic requiring:

def update_params
  [:integration_webhook, :integration_slack].each do |model|
    return params.require(model).permit(:filters) if params.has_key?(model)
  end
end
