Where should I put code (let''s call it a library function, perhaps) that is to be made available in several views, even views related to different models / controllers? Is that what the "lib" directory is for? Or maybe the controllers/ application.rb file? And, how do I access this code later, in a given code? I''m guessing I have to do "require". I am wary of experimenting with such things in RoR, because I''d like to start following best practices, as viewed by the community. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Can you give an example of what you''re trying to accomplish?

For a sitewide navigation bar, you should do a shared partial.
In "views," put a file called _nav.rhtml (or whatever).
Then in your default layout, or wherever you might want to call it,
you can put
<%= render :partial=>''shared/nav'' %>
The partial should pick up any instance variables (variables prefixed
with ''@'') you send to it, but if you want to define a variable
specific to that partial, you can do it like this:
<%= render :partial=>''shared/
nav'', :locals=>{:this_section=>''articles''}
%>
Which gives you access to a variable inside the partial called
this_section with the value ''articles''.
If you''re talking about something specific to one of your models, you
should put it in the view for that model. Let''s say you want to put
user''s account info on every page. You might do something like this:
VIEW:
---------------------------------------------------
/views/user/_account_info.rhtml
---------------------------------------------------
Hi, <%= @this_user.name %>!
CONTROLLER:
---------------------------------------------------
application.rb
---------------------------------------------------
:before_filter :get_this_user
def get_this_user
@this_user = User.logged_in_user(session[:this_user_id])
end
MODEL:
---------------------------------------------------
user.rb
---------------------------------------------------
def self.logged_in_user(id)
find(id)
end
Then anywhere in your application you can put:
<%= render :partial=>''user/account_info'' %>
This may be too much info (or not enough) but I hope it helps.

I see a couple of sloppy errors in my example: The shared partial should go in views/shared (not just views), and before_filter should not have a colon in front of it. Yes before_filter :whatever No :before_filter :whatever Anyway, best of luck.

I am trying to use the :click_to_edit_text attribute for in_place_editor_field, but nothing shows up. Any trick that I need to be able to pass in a default value for an in place editor?

There are two hashes at the end of the argument list for in_place_editor_field. If all you want to change is the hover text: <%= in_place_editor_field ''person'', ''eye_color'' {}, { :click_to_edit_text => "Please click me!" } %> If you just have arguments like <%= in_place_editor_field ''person'', ''eye_color'', :click_to_edit_text => "Please click me!" %> the option will be part of the hash for the tag_options rather than the in_place_editor_options. -Rob Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
