How to append to models errors collection?

Rails
1

I want to append to my models error collection from another models
errors
like:

@user.errors each do |e|
@post.errors << e
end unless @user.valid?

But it says:

'undefined method << for activemodel post …

What is errors then, a hash?

puts, awesome print, pry, ruby-debug are all great tools you might try
before bringing this up on the list:

Try:
@user.errors each do |e|
puts @post
puts @post.errors
puts @post.errors.class
@post.errors << e
end unless @user.valid?

then run your test again.

Have a google rails merge errors - Google Search

You don’t say what version of Rails you’re using, but historically I
have posted up a solution for 2.3.x

Assuming both instance vars have bene instantiated correctly
previously…

@user.errors.each { |k,v| @post.errors.add(k, v) } if
@user.errors.any?

should do it.
