Re: [Rails] Re: form_for, need to modify the :url based on if it is persisted or not

Thanks.

When you add something to a helper like articles_helper, does it have the request object in there also?

How does it get the @articles object when I call it like:

form_for @article, correct_post_path, ...

I would have though it would be:

form_for @article, correct_post_path(@article), ...

You can create a helper method (in helpers/articles_helper.rb):
 def correct_post_path

   @article.persisted? comment_article_path : articles_path

 end

And then use this helper in your form builder
 form_for @article, correct_post_path do ... end

That helps ? Maybe you can tell us under what conditions you need to
change post url, maybe you over-engineer somewhere...
