I must be missing something, because I don''t get a clean way how to
do this.
I have a page which when you change the contents of a select, changes
the contents of a div by calling an action.
How do I have the contents of the div be the results of calling the
action on the initial page load? I understand if I wanted to render
just the template I could use partials, but I also need to have the
action function called.
NOTE: the main action should not depend on whether the updatable
piece is included on the page.
ie,
controller:
def main
...stuff...
# should not care if page has a change_piece on it, so should not
need to do change_piece stuff
end
def change_piece
...stuff that must happen...
when called by ajax:
render :update do |page|
page.replace_html :bob, :partial => "piece"
end
when called as part of initial page load:
render :partial => "piece"
end
view (main):
<html>
...stuff...
<div id="bob"> <%= render :action "change_piece"
%></bob>
...
</html>
I tried using render_component, with a respond_to block in the
action, but it just renders the first thing in the respond_to block.
IE, if I have format.html first it renders that first. If I have
format.js first, it renders that. (the respond_to block works
correctly otherwise)
Thanks,
Michael Johnston
