Outputting a rails url to javascript

Rails
#1

Hi,

I’m working on a rails/google maps app, where makers on the map show
‘places’. I would like to be able to put a link into each marker’s
infowindow that will take the user to the ‘show’ action for that place
(ie. /places/[place_id]), and am looking for ways to output the
appropriate url so it can be incorporated into my /public/javascripts/
map.js file. I’m using json to output the latititude, longitude, name
etc of each place to the map…is there a way to extend this to urls?

Any help would be much appreciated, thanks in advance!

FYI: Rails 3beta4, Ruby 1.8.7 and using jQuery with my map.

Of course! URLs are just strings. Stick 'em in the JSON packet with
everything else.

Any help would be much appreciated, thanks in advance!

Awesome, I hoped it would be that easy! Thanks for your help

I’ve found a solution - instead of adding a ‘link’ column to my
‘places’ table, I can just use the place id value to create a link in
my js file:

Show more!"

Hope that sounds okay, it seems to work fine!

Hi,

I’m struggling a bit to get an appropriate url to save - I’ve added a
‘link’ column to my ‘places’ table, and am populating the hidden form
field automatically using @place.link = places_path(@place.id) in the
‘new’ action of the places controller. This seems to output just /
places however - am I going about this the wrong way? I’m also
struggling to incorporate the /places link I’ve exported to JSON into
my javascript code…thanks for your help!

A minor observation:
I suppose you are taking care of nil objects here: place.id. Otherwise
the link will crash if “place” object is nil. I would propose doing
something like:

place_id = place.id rescue “” # or you put your rescue sub-link here
“Show more!”
