Rails - 保存到數據庫時，是否有一種方法可以從所有字段中去除HTML？

Question

或者你真的需要單獨清理每個領域？謝謝

Answer 1

您可以使用列元數據遍歷每列。

（從http://blog.hulihanapplications.com/browse/view/10-strip-html-in-ruby-on-rails）：

class Product < ActiveRecord::Base 

before_save :strip_html 
def strip_html # Automatically strips any tags from any string to text typed column 
    include ActionView::Helpers::SanitizeHelper 
    for column in Product.content_columns 
    if column.type == :string || column.type == :text # if the column is text-typed 
     if !self[column.name].nil? # strip html from string if it's not empty 
     self[column.name] = strip_tags(self[column.name]) 
     end 
    end 
    end 
end
