Executing a model from two different controllers - one contr

Rails
1

My appllication uses a “Video” table. I have a video_controller and
associated video model

The video_controller requirs the user to login to the system.
class VideoController < ApplicationController
before_filter :login_required

When I initially wrote code for the Video model, I assumed that only
authenticated users would read, write Video records. Hence, I’ve got
code in the model such as:
@dir = ‘public/uploaded_videos’ + “/” + User.current_user.id

The above works fine when a logged in user accesses video functions on
the site.

Now, I want to display a list of videos on the Index/home page of the
web application. Users who access the web page don’t need to log in to
the system.

I created a home_controller with an index method.
def index
@videos = Video.find(:all, :conditions => [“public = 0”], :select =>
[‘id, file_name, file_size,thumbnail’])

end

Whenever, this method is executed, RoR makes a call to the video.rb
file and fails on the following line:
@dir = ‘public/uploaded_videos’ + “/” + User.current_user.id

It’s failing because User.current_user.id is null. This value is only
populated when a user logs into the system.

How can I get around this particular issue?

not that it makes any difference (you’ll still solve the problem
regardless, but for general knowledge, where is the @dir statement being
called … ?

either way, just add a ‘unless User.current_user.nil?’

@dir = 'public/uploaded_videos' + "/" + User.current_user.id

@dir = 'pub … + User.current_user.id unless User.current_user.nil?

should solve the problem, no?

I just want to point out something, the code above should not be in the
model, but in the helpers.

Thank you. That worked perfectly.

I had previsouly tried using an if statement with the same condition:

if !(User.current_user.nil?)

DIRECTORY = ‘public/uploaded_videos’ + “/” + User.current_user.id

end

It seemed like the if statement was being ignored.

@dir is being called from other methods within the model. I’m using it
ti define the destination file path for encoded video files.
