在Rails中创建新模型时,是否有一种在所有上使用strip的干燥方法:params?

我有一个表单来创建一个新的Contact模型。

我通过切割和粘贴手工输入值。

有时我最终会在左右两侧添加空白区域。

这是创建控制器中的内容(我有一个循环,检查我是否上传了一个vcard,显然,通常不会出现问题(尽管可能) – 但我的大问题是我自己输入它。

def create @contact = Contact.create(params[:contact]) unless @contact.vcard.path.blank? paperclip_vcard = File.new(@contact.vcard.path) @vcard = Vpim::Vcard.decode(paperclip_vcard).first @contact.title = @vcard.title @contact.email = @vcard.email @contact.first_name = @vcard.name.given @contact.last_name = @vcard.name.family @contact.phone = @vcard.telephone @contact.address.street1 = @vcard.address.street @contact.address.city = @vcard.address.locality @contact.address.state = @vcard.address.region @contact.address.zip = @vcard.address.postalcode @contact.company_name = @vcard.org.fetch(0) end @contact.user_id = current_user.id # makes sure every new user is assigned an ID if @contact.save #check if need to update company with contact info @contact.update_company @contact.new_todos #create the todos for the newly created contact flash[:notice] = "Successfully created contact." redirect_to @contact else render :action => 'new' end end
