Model error_messages_for

Rails
1

I have this in my form view:

<%= error_messages_for ‘post’ %>

I’m not using form_for, just a regular form_tag:
<% form_tag :action => ‘save_requirement’ do %>

The error messages do not pop up, any suggestions?

Thanks!

is @post an instance of an activerecord object with some errors?

Yes,

controller:

def new_requirement
@post = Post.new
end

def save_requirement
@post = Post.new(params[:post])

  if @post.save
    redirect_to_index("Thank you for your post!")
  else
    redirect_to :action => :new_requirement
  end

end

Ah! Great David!

Thanks so much, it works!

In the failure case, you don’t want to redirect; you want to render.
Redirecting triggers a completely new request cycle, with a new
controller instance, and all instance variables are reset to nil. So
@post will be back to being a new Post instance, which will not have
any errors, so no errors will be displayed.

If you render, on the other hand, you’ll just be rendering the
new_requirement template with the existing @post object, which does
have errors.
