How to redirect_to index action after update

[goodieboy]

Hi,

I'm doing an update on the index page. There is a little form for each
of the items in the list. I'd like to be able to do an update on a
give item, and then have the controller redirect to the SAME index
url. How is this possible with r_c?

Thanks and thank you for such an awesome project!

Hi Matt,

I'm not totally clear on what you're asking. If you are simply asking
how to change the redirect from the update action, try this:

update.wants.html { redirect_to collection_url }

Otherwise, I'll need some more details.

Hi James,

I've got a list of products. The list has a little text fields for
entering the position number. What I want to have happen is to have
the form call update for the given product, and after the update,
display the index page again. I actually got it working by doing this:

def update
unless params[:product][:new_position].nil?
Product.find(params[:id]).new_position=(params[:product]
[:new_position])
respond_to do |format|
format.html {redirect_to collection_url}
end
else
super
end
end

Is there a cleaner way to do this? :)

Thanks,
Matt

So, the update is performed differently, depending on the params
present? If it's a totally different update, I think what you've done
is the clearest method.

Hi James,

The update is performed differently yes, but doesn't have to be. I'm
just doing a standard update, but on only one attribute. So, what I'd
really like to do is have a_r handled everything, but then just handle
the response and redirect to the index page instead. Is there a way to
do that?

Thanks,
Matt

Yes, I think that's a much better approach.

In that case:

  update.wants.html { redirect_to collection_url }

I see, but the problem I've had is that I need to check for the
presence of a certain request parameter. But I can't access the params
from within the block. Do you know how I could access the params
array?

If I could just do this:

unless params[:new_position].nil?
update.wants.html { redirect_to collection_url }
end

I'd be set! Any ideas on that?

Thanks,
Matt

You can't access the params from inside of the block? I don't seem to have any problems doing

update.wants.html {
  unless params[:something].nil?
   redirect_to collection_url
  end
}

Which version of rails/r_c are you on?

Cool, I ended up doing this:

update.wants.html {
redirect_to params[:id] ? collection_url : object_url
}

And it works great. Thank you!
