Redirect_to results in "syntax error" for <!DOCTYPE HTML...>

Rails
1

Hi there,

I have a strange error:

In a controller, I have a…

redirect_to :action => ‘show’

…at the end. But upon code execution, Firebug tells me:

syntax error

(It says that for Line 0)

Does anyone have a clue what this means and where the problem lies?

Just in case:

  • I have also tried to use the “loose” version in the HTML code:

But it didn’t change anything.

  • redirect_to a different :action works.

Thank you for any help with this!

Sounds like you redirected to an html page but your stuff on the page
was expecting to get some javascript back (ie you were using
link_to_remote etc… without an :update option)

Thanks for your (actually super-quick) reply, Fred!

To paraphrase it (correct me if I’m wrong):

Whenever an Ajax request is sent (i.e. using submit_to_remote) the
“rendering part” in the controller can NOT use “redirect_to :action =>
…” or “render :action => …”.

Rendering the response can in this case only be done using:

render :update do |page|
page.replace_html ‘whatever’, :partial => ‘whatever’
end

“redirect_to” and “render” can only be used after “regular” requests.

It depends on whether link_to_remote, submit_to_remote etc… have
been passed the :update option.

  • if they have then they are updating an element on the page and you
    need to generating a normal html fragment
  • if they are not then they are expecting javascript, so using
    render :update and so on is compulsory.
