What are you trying to do?
Couple things I'll mention now

Html5 getusermedia you can grab a users webcam and mic

If you are wanting to share vid streams youre going to need a server. Darwin qtss for mp4 or icecast2 which does theora vid.

Then one just connects the users webcam source to the broadcasting server

I do a create on an Active Record model in a controller and it's doing
something strange. It's primary key (id) is nil, created/updated are
nil as well.

A few of the columns/attributes are nil as well. The model instance
gets created but the id is nil.

Rspec fails for the model because its id is nil (because it's being
passed to other models)

Any ideas?

Thanks for your feedback Fred.

I should have added that I'm using very old Ruby (1.8.7) and Rails
(2.2.2) versions.

Also, I tried to make my example as simple as possible. In reality, it
is a little more complicated.

The error is that...

...if I invoke an action on the UserController which is implemented in
its base controller, even if the base controller has a before_filter
excluding auth_check to run for that action it will still be run unless
UserController explicitly excludes the auth_check from running for the
inherited action.

I've been debugging this and can see that the debugger first processes
BaseController.before_filter followed by UserController.before_filter
but I don't know how the filters are stored and chained. I think that is
where the problem is.

Being old(er), I'm like you. The kids all use nginx these days, often with thin as the webserver. Your mileage may vary.

Obviously, if you're using websockets, you'll need an architecture that supports that.

Thank you to Vivek and Jason.

One extra note: this is an internal restricted web site so I can't use
Heroku for this particular project but that type of information is also
interesting to me.

On a side note: in the past, I've used Apache. Sometimes with Passenger
and sometimes without. I'm curious on httpd recommendations as well.

Thank you again,

You may also want to look into recently introduced Websockets functionality on Heroku

Thanks Colin.

Another person suggested this:

resources :comedy do
collection do
get :play_quiz
end
end


class ComedyController < ApplicationController
def play_quiz

end
end

Would this be preferable?

I'm starting a new Rails project probably using 4.1 or 4.2. The project
needs the ability for user's browsers to get updates via push
notifications. I know that Rails 4 kinda sorta added that but the last
time I looked it was shaky.

To sketch out what I'd like: suppose a user is looking at a page.
Think of it as a user looking at a history of activity for a project.
Another users does an update. I want the first user's browser to get
the new update. I don't think will work in this situation so I'm
looking for the server to push the updates out.

What is the current technology? Does Rails 4.1 or 4.2 have everything
it needs or do I still need some add on gems? If so which ones? If
Rails is complete, what are some areas of the Rails documentation to
review?

Thank you for your time,

You would probably want to make a counter cache for tasks on the project (you can find out more here: http://api.rubyonrails.org/v4.1.1/classes/ActiveRecord/Associations/ClassMethods.html#method-i-belongs_to), and additional when retrieving tasks from the database, when you know you will need their project data, use eager loading (more here: http://guides.rubyonrails.org/active_record_querying.html#eager-loading-associations).

Michał.

In a todo list-style app, I have the following ActiveRecord model method:

class Task < ActiveRecord::Base
  # ...
  def project_name
    project.tasks.length > 0 ? "#{project.name} - #{name}" : project.name
  end
end

The idea is to provide additional project information if there are one or more tasks on the project.

However, when invoked regularly on views this creates performance concerns (especially with a growing data set).

What is the best way to optimize this query so that it doesn't create N+1 query type issues when invoked from "each" loops in the view?

(Feel free to post answers on StackOverflow).

I have something like this:



=========================================================================
class ApplicationController < ActionController::Base
def check_auth
# ...
end
end

class BaseController < ApplicationController
before_filter :check_auth, :except => [ :getSession ]
# more here...
def getSession()
# ...
end
end

class UserController < BaseController
before_filter :check_auth, :except => [ :getNotifications ]
# more here...
def getNotifications()
getSession()
# ...
end
end
=========================================================================

I'm was expecting wrongly that if UserController#getNotifications calls
BaseController#getSession check_auth would not called.

If I change the before_filter in my UserController to:

before_filter :check_auth, :except => [ :getSession, :getNotifications
]

it works as expected.

Isn't there a way to incorporate the before_filter settings from the
parent controller say during construction of an instance of a sub class?

Thanks for any help in advance
Pete

Ah, you could be right.
@Aspiring Student if so then copy the error out of the server terminal
window and paste it here, assuming it is in the server window.  You
may have to use Ctrl+Chift+C to copy from a terminal window.
If it only appears in the browser then just retype it if you can't
copy text out of it.

You say it is an error but it does not look like an error message, it
looks like some html generated by an image_tag or similar.  Show us
the line in your view that is generating that.  If it is not coming
from a line in your view what do you see in development.log when it
happens?

I have search tool like "Java Media Framework"

for Rails application.
Anybody knows that please suggest me.!!!
