jquery ruby-on-rails load partial

Im curious about what the best way to load a rails partial with jquery. So far I have tried a solution not working:

$('#imagecontent').load('/newsletters/_image_gallery.html.erb', function() {
alert('Load was performed.');
});

Is the best solution to build a seperate action and/or controller for this and set up a route? Im asking because making the first solution work seems more easy, perhaps not so restful.

Thanks.

You should not be able to access Template files (.erb) from HTTP requests, this is very bad practice. I suggest you put them outside your web servers path and access them only through your application.

I'm not sure about Rails, but I suppose you need to create a separate controller (or whatever) to do this.

EDIT this is because .erb files are Embedded Ruby files, and if you try to request them you will get all unwanted data, like <%= page_title %>, that you don't want to show the users. Therefore you need to pass these .erb files through your Rails application so that they are properly interpreted into HTML.
