问题
How shall I set the form fields to be able to insert multiple rows in the database for a single model.
I am updating a div with another link and cannot use the form helper. So I need to set the field names manually.
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.
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
And still nothing is saved.
回答1:
posts = Array.new
posts << {:title => "title 1"}
posts << {:title => "title 2"}
Post.create(posts)
回答2:
is this what you're trying to do?
posts = []
posts << Post.new(:title => "title 1")
posts << Post.new(:title => "title 2")
posts.each do |post|
post.save
end
