form_for, need to modify the :url based on if it is persisted or not
My have a form in a partial like this: form_for @article, :url => articles_path, ..... Now currently it posts to the create action. I want it to post to comment_article_path under certain conditions, how can I do this? Can I put in a expression like: @article.persisted? comment_article_path : articles_path Is this good practice? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

It can certainly be done easy enough, but I''d question the problem you are trying to solve if you want to do something like that. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

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...

Re: 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), ...
