Message-ID: <4AC4FC04.4040608@indra.com>

I have a spare office available if anyone is looking for some space. 
Nice office, conference room and kitchen use, parking, and lots of 
bandwidth (we're an ISP).  I'm the lone developer here and it would be 
nice to have peers around.

Details: http://boulder.craigslist.org/off/1392135704.html

I'll throw in a couple of Us in our data center as well.

Hey everyone, I'm either blind to the obvious, or I'm being overly  
complicated.

I created a site that tracks events.  Originally (out of ease and  
speed) I created a text field for the location of the event.  My  
users (rightly) got tired of doing the copy/paste shuffle every time  
they wanted to create a new event.  As there were only a handful of  
locations being used I figured it would be nice to break out the  
locations into their own model/controller and create a one-to-many  
association (event has one location, location has many events).  This  
way, I can switch the location selection in the event form to a drop- 
down.  Easy!

The events table now has a location_id foreign key and there's a  
"belongs_to :location" in the events model.  The locations model has  
a "has_many :events" but it doesn't seem really necessary; there's no  
need or desire from the users to list the events by location.  I've  
added it simply because every single example of a one-to-many  
association is built that way, though from what I' can tell  
"has_many" does not require anything in the locations table, it only  
generates a method that runs through the events table looking for a  
matching id in the locations_id foreign-key column. (eg:  
@location.events Follow? :) )

So to just to get things rolling, in views/events/show.html.erb I  
have the following section:
<p>
   <%= @event.location.name %><br />
   <%= @event.location.address1 %><br />
   <%= @event.location.address2 %><br />
   <%= @event.location.city %>, <%= @event.location.state %><br />
   <%= @event.location.zip %><br />
   <%= @event.location.other %><br />
</p>
(there is also a location.label, which is a short nickname used in  
the location drop-down)

Anyway, I figured it would be much more DRY to just call the "show"  
view/action in the Locations controller from within the "show" view  
for an event.  IE, when I "show" and event, it "show"s the location.   
Nice and OO right?

It's either not so easy, or I'm off in left field.

The closest I can get is <%= render 'locations/show' %> but of course  
@location isn't set, so that does nothing.  I tried adding "@location  
= Locations.find(@event.location_id)" to the show action in the  
Events controller, so that the above render would have a @location  
when it got to the view, but I get the error "uninitialized constant  
EventsController::Locations".  (also tried find_by_id)

Not sure what to do, but since I've been banging my head against this  
for two days, I'm a bit numb.  Overload a 'find' method in my  
Location model (not the controller, the model)?  I hate leaving it as  
above, but I since the ugly works, I'll just put white-out on my  
screen whenever I edit that file.

All thoughts welcome!

Bob:

Not sure that I follow what youare looking for here, but either way I  
interpret it, you are looking for a shared partial.

Do this... in the app/views directory create a 'shared' directory, if  
one doesn't already exist.  Make it something like:

shared/location.rhtml (sorry, too old school to do the .erb thing)

In it, place a simple block:

<p><%= location.name %><br/>
  	<%= location.address1 %><br/>

... etc ...

</p>


Then, in a view that comes from the event controller, you can do:

<h2>Event</h2>
<%= @event.name %><br/>
<%= @event.contact_info %><br/>
<%= render :partial => "shared/location", :object => @event.location  
(or :locals => {:location => @event.location}) %><br/>

... etc ...

In the location controller, you can also use it, pushing @location  
into :object (or whatever).

There is more info here:  http://api.rubyonrails.org/classes/ActionView/Partials.html

and here:

If you have any questions, feel free to shoot me an email.

Thanks,

Just a nit... You will need to start the file name with an underscore 
for Rails to recognize it as a partial. shared/_location.html.erb (I'm 
definitively not old school) would work.

Ha!  That worked. :)

Right, and I'll probably shift to partial, but the catch when using  
render is that it does not execute the other controller's action  
code.  So, if you have controller XYZ with action 'show' and a  
show.html.erb, "render XYZ/show" will choke if it depends on a  
variable set in action XYZ.show.  So even a partial would have choked.
The secret above is that "@location = @event.location" needs to be  
set in the show action of the Events controller, which i suppose is  
fine since I've defined the one-to-many association (an event must  
have a location) but it doesn't seem to me to be cleanly OO. (?)


Of course, as soon as I get the answer, I discover something else  
that works.  From http://guide.rails.info/layouts_and_rendering.html:
----
Every partial also has a local variable with the same name as the  
partial (minus the underscore). You can pass an object in to this  
local variable via the :object option:

<%= render :partial => "customer", :object => @new_customer %>

Within the customer partial, the customer variable will refer to  
@new_customer from the parent view.
----
:|
I swear I read that section twice and didn't see that little tidbit.

So!  What I've got now is,
  <%= render :partial => 'locations/location', :object =>  
@event.location %>

after copying show.html.erb to _location.html.erb, and changed all  
the "@location.xyz" refs to "location.xyz" (eg: location.name, etc).   
That works!


I can actually feel myself getting smarter.  You guys are awesome.
Thanks!
