Sorry for not answering the question, but I cannot contain my
curiosity to know why you need to do this.

[Rails] Re: Re: How install libv8 (therubyracer) Windows 7

Hi Everaldo,

[Rails] Scaling challenge

[PierreW]

Hi guys,

Our app has been getting traction recently, and we struggle to cope with 
the traffic. I was hoping you guys could point me in the right direction.

For each request, the app does some heavy calculations. They are not done 
in Ruby, we use a compiled, shared lib for this. Our current architecture 
is:

- user request triggers 2 background jobs (via Workling/Starling)
- the first worker does some pre-processing (including polling the DB), 
call the shared lib, and loop. It sends results along the way to the second 
worker.
- the second worker does some post-processing and sends results back to the 
app.

I think the key problem is the call to the shared lib is blocking, so when 
we get lots of calls at once, it seems to me all the workers are stuck on 
this lib and nothing else happens (there are a limited number of workers).

I have a couple of options in mind, but I have no idea which one should 
give better results:

- upgrade to Ruby 1.9.3 (from 1.8.7)
- migrate from DL/Load to FFI (but I don't believe it sorts the blocking 
issue)
- consider another Ruby implementation
- consider a different architecture. For instance I could run this shared 
lib on a separate instance without anything else (just Ruby processes) but 
I am not sure how to do this considering speed will be key.


Thanks!
PJ

Dear Tyler

I don't want to store password in plain text in database. I just want to 
send an email to user that your login & password is this. Devise will 
store password in encrypt form in database.

I understand the use case, but still doesn't make sense to store the 
password in plain text in the database.  It's actually even more pointless 
if all the users are admins... then they call all just see each others' 
passwords.  And it gives the illusion of security, when in actuality it's 
one params vulnerability away from giving all-encompassing access to any 
hacker that wants it

[Rails] retrieve model name from table name rails 3

[VIKRAM KUMAR MISHRA]

Hi All,

 I want to derive the model name from table name. 

One method i got is using table_name.classify. But this does not give 
actual model name. The scenario is

Class User < ActiveRecord::Base

   self.table_name = "abc_xyz"  

end

Now i want to retrieve the model name from table name "abc_xyz" which 
should be User.

Any help is highly appreciated.

Thanks
Vikram

I think you need a separate model that will aggregate data from others.

strip removes ONLY leading and trailing whitespaces, see:
http://www.ruby-doc.org/core-1.9.3/String.html#method-i-strip

Basically, PHP's trim() works the same.

If you want to remove whitespaces inside the string, you need to use
`String#gsub` or `String#squeeze` (depending on what you want to
achieve).

He disallows users to register. So only admin can create a user
account, so he wants the system to send a message to the user that his
account was created with such and such login and pass.

How is the initial pwd being setup?  If the admin is providing a
password then put that in the email.

[Rails] Re: How to get password from database using devise

[Tyler]

Why do you want the password in "readable" form?  That goes against the 
most basic point of even having a password...

There should be very little logic in the controller, but logic in the
controller is usually best moved to the models.  Helpers can be used
to remove logic from the view.  Can you give an example of the sort of
logic you are talking about?

[Rails] help with design issue

[Shalini Sah]

Hi,

I am a newbie in rails. I am creating a rails app where I query an existing 
database consisting of multiple tables. I created a model file 
corresponding to each database in the model folder. Now the problem is I 
want a consolidated view for all the models. My app will basically take 
some inputs from user and generate a summarized view based on the  given 
inputs by querying multiple tables (and thus interacting with many models). 
So shall i create just one controller and put the entire logic in it?? or 
can i transfer some logic to helpers? What would be the ideal design in 
this case?

Any help is really appreciated!!

Thanks & Regards,
Shalini Sah

The way that I handle this in my applications is to use Devise Invitable, and 
then restrict the invitation privilege to admins. You don't get to know the 
password, because the user sets it herself when she accepts the invitation. But 
everything else just works. Since you aren't using registerable, you will need 
to provide your own "Update my Profile" method in a controller if you want to 
allow the user to update his profile, but that's covered in the Wiki.

mail is

Because the author forgot about find_by_id, which would accomplish the

If you're looking to grab all the queries, check out the Notification

the 'sql.active_record' notification will be fired every time there's a

[SOLVED]  assigns(:blog)  is OK because @blog is created in the test

You have not explained well what you are trying to do, but possibly
you want to loop through the cardlevels instead of the cards, then for
each cardlevel you can obtain the card aswell as the other data, so
something like

<% @user.cardlevels.each do |cl| %>
<%= cl.card.name %>
<%= cl.other_data %>
<% end %>

You might need to check for cl.card nil though.

[Rails] Re: Associations join

[Timen E.]

Still got one(Hopefuly last for now) question, guys.

I've got the above data now and i can access my cards through users that 
are joined by the cardlevel. I'm trying to loop through all the cards a 
user has as such:
<% @user.cards.each do |c| %>
  <%= c.name %>
<% end %>

And this works great. However i'd like to get some extra info about this 
card from my cardlevel array, but i can't seem to access it like this. I 
can however loop it in a seperate each, but i don't want that obviously.

Any ideas?

Thanks

aaah i see, nonetheless i noticed that i turned it around. I need to get 
the user with it's cards, haha!

What you mentioned did work but it doesn't seem to 'associate' the right 
way around because i'm getting the error SQLite3::SQLException: no such 
column: cards.user_id: SELECT "cards".* FROM "cards"  WHERE 
"cards"."user_id" = 1"".
Shouldn't he query through cardlevels instead of cards?

You would have been better to put @cards = Card.all as the result will
be be an (effectively) an array of cards not a single one.

The clue is in the error message, as is often the case, it says that
@card is an Array and the Arrray class does not have a method user.
You can only call user on an individual card.

@card is a collection of cards (that's how you populate it in the
"show" action. If it needs to be a single card, you need to find it by
ID (or some other attribute), if it's supposed to be a collection of
every card, you need to iterate it in the view and print the user for
each card.

I've just got a really basic setup to see if i got it working:


card.rb
class Card < ActiveRecord::Base
attr_accessible :attack, :defense, :name
has_many :cardlevels
  has_many :users, :through => :cardlevels
end

cardlevel.rb
class Cardlevel < ActiveRecord::Base

belongs_to :user
  belongs_to :card

user.rb
class User < ActiveRecord::Base
attr_accessible :name
has_many :cardlevels
  has_many :cards
end
-

card_controller.rb
class CardController < ApplicationController
  def show
@card = Card.all
  end
end

User & cardlevel are empty for now
-

Card#show
Find me in app/views/card/show.html.erb
<%= @card.user %>
Where i tried eaching the @card, tried @card.users, @card.user.name etc. 
etc.

Do you know the html that you want to generate?  If not then this is
not a Rails question but an html question, in which case the best
thing to do would be to work through some html tutorials.
