Rails为单个模型插入多条记录 [英] Rails inserting multiple records for single model

问题描述

我应该如何设置表单字段以便能够在数据库中为单个模型插入多行.

How shall I set the form fields to be able to insert multiple rows in the database for a single model.

我正在使用另一个链接更新 div，但无法使用表单助手.所以我需要手动设置字段名称.

I am updating a div with another link and cannot use the form helper. So I need to set the field names manually.

我有一个帖子模型，它有一个标题字段.我想像 post[0][title] 这样将 i 帖子插入到 db 但是当我像这样命名表单字段时，它得到 0 作为字符串并且不记录.

I have a post model and it has a title field. I want to insert i posts to db like post[0][title] But when I name the form field like this It gets 0 as string and does not record.

我还尝试从 Rails 控制台设置我自己的数组，例如

Also I tried to set the Array my self from Rails Console like

post = Array.new
post << [:title => "title 1"]
post << [:title => "title 2"]
sav = Post.new(post)
sav.save 

仍然没有保存任何内容.

And still nothing is saved.

推荐答案

posts = Array.new
posts << {:title => "title 1"}
posts << {:title => "title 2"}
Post.create(posts)
