I have a VERY hierchical database and am using a RESTful
approach. Normally, when users’ enter the system they’ll cascade
from
level to level in the database and thus the hierchical information
such as child.parent.grandchild_id are always available to the
RESTful
routes.
However, when I attempt to directly call a middle level table.index I
obviously fail, because the parent_id is not available to pass to the
RESTful route.
I’d like to have a ‘safety mechanism’ built into my code that handles
this by simple displaying all records irrespective of parent.id.
Here is an example of my before_filter event and the way I use it
to call my index:
def find_parent
@find_parent || @project = Project.find(params[:project_id])
end
Here is a typical table.index action:
def index
@portals = @project.portals.find :all
Would it be possible to make the INDEX code something like this;
def index
if @project.nil?
@portals = Portal.find :all
else
@portals = @project.portals.find :all,
end
Fundumentally, what 'blows my mind' is that the 'find_parent'
‘before_filter’ event ALWAYS has to fire and if no parent exists, I
can’t see how to return a ‘[email protected]’ or whatever is needed to
feed
the if, else routine (above)?
Thank you,
