无法弄清楚如何更新邮箱 is_read [英] cannot figure out how to update mailboxer is_read

问题描述

我正在使用邮箱管理器 gem 并且我正在尝试使用它，以便在我查看对话后(通过访问对话#show)，我希望收据的 is_read 属性变为真.但是，在我发送回复之前，该属性不会变为真.我尝试使用以下行:

I am using the mailboxer gem and I am trying to make it so that after i look at a conversation (by accessing conversations#show), I want the is_read attribute of the receipt to turn true. However, the attribute will not turn true until I send a reply. I tried using the following line:

receipt.update_attributes(is_read: true) 

但返回以下错误:

Error (ActiveRecord::ReadOnlyRecord)

我想我理解错误.我认为这是说该属性只能读取而不能更新.我的问题是，如果我转到对话#show 页面，如何实现让 is_Read 变为真的功能?

I think I understand the error. I think it is saying that the attribute can only be read and not updated. My question is, how do I implement the functionality to have is_Read turn true if i go to the conversations#show page?

推荐答案

不要更新 is_read 属性试试这个

Instead of updating the is_read attribute try this

#conversations_controller.rb
def show
  @receipts = mailbox.receipts_for(conversation).not_trash
  @receipts.mark_as_read
end

private

def mailbox
    @mailbox ||= current_user.mailbox
end

def conversation
    @conversation ||= mailbox.conversations.find(params[:id])
end

您还可以将整个对话标记为已读

You can also mark a entire conversation as read with

conversation.mark_as_read(current_user)
