Tracking Specific model instances about public_activity HOT 7 CLOSED

I guess I need to use recipients somehow..
Can I have a list of recipients?

from public_activity.

It seems the best way to do this is to use 'activist' in the user model and then for each user @alice tracks to list their activities ordered by created_at.

is that a correct implementation?

from public_activity.

By

@alice wants to track everything that @bob does (on all models)

you mean that Alice would like to see the activities Bob did? This is outside of the scope of my gem. If you want to display activities of Bob you'd do something like:

PublicActivity::Activity.where(:owner => User.where(:name => "Bob").first)

It's in your application responsibility to determine whether current_user(@alice) can see activities performed by Bob.

About 'recipient': You can use this to "send" private activities. For example if userA comments one of userB's posts, the it is natural that only UserB should be the recipient of this notification. So you set recipient to userB.

Is the usage of 'activist' and doing @bob.activities (if @alice needs it) also acceptable? its not really documented...

from public_activity.

Activist is bound to "owner'. So if you do @bob.activities it's actually executing query to get all activities performed by this user:

PublicActivity::Activity.where(:owner => @bob)

acitivities is merely a has_many :activities relation. Like I said, I don't implement more complex logic, because that would interfere with custom implementations.

Let's assume you are writing a Facebook clone, where people have friends. It's obvious that I, as user, am only interested in activities performed by my friends. So you can do something like:

PublicActivity::Activity.where(:owner_id => current_user.friends.collect {|friend| friend.id}, :owner_type => "User").order("created_at DESC")

This will return the newest activities performed by current_user's friends.

ok that's exactly what I need.

note that in the code comments it says the for activist only activist needs to be added.
That didn't work for me as I needed to also add include PublicActivity::Model to the user model

Thanks for pointing it out, and mentioning your concerns. I will definitely improve the documenation based on your input 👍 We are refactoring p_a, expanding docs and adding new features so at this level not everything is documented as it should be.
