You would need a separate controller to handle the sign-in part, with its own views. When it's successful, it should redirect you to the A controller. This is how most apps do it.

First make sure your OpenSSL is working fine, then make sure you've
the SSL headers installed and recompile Ruby. Also, see if the
simplest form of connection works:

require "net/https"
Net::HTTP.get(URI.parse("https://us1.api.mailchimp.com/2.0/helper/ping"))

Please don't top post, it makes it difficult to follow the thread.
Insert your reply inline in the previous post. Thanks.

Have you got a column in the db called frozen? If so then it is
warning you that the name conflicts with an ActiveRecord method.

We are not telepathic so without knowing what you are doing it is
impossible to say.  Post the full error and stack trace  (if any) and
the section of code causing the problem.  Not your whole app just a

[Rails] Re: Puma fails when it restarts itself - SOLVED

Ruby on Rails

FIXED
I had the restart_command in puma.rb trying to run 'puma.sock restart', I pointed it to my init.d file and it no longer has an issue when it boots workers

restart_command '/etc/init.d/puma restart'

I still occasionally get a 504 timeout under very heavy load, but i have the god gem monitoring too and it recovers from that quickly




On Thursday, August 29, 2013 5:51:24 PM UTC-4, Rob Daniels wrote:
I'm having an issue with Puma, it fails when it tries to restart itself. When this happens it kills all the Puma processes, resulting in nginx delivering a 502 Bad Gateway to our users. I'm able to start, stop & restart it with my /etc/init.d/puma script (it runs /usr/local/bin/run-puma),  it just has issues when it restarts itself. The puma.log file doesn't show anything just useful for troubleshooting, just

Puma starting in single mode...
* Version 2.5.1, codename: Astronaut Shoelaces
* Min threads: 16, max threads: 32
* Environment: production
* Listening on unix:///home/deploy/app/shared/sockets/puma.sock

and my workers. Any help would be greatly appreciated.

Also - i have whats probably a pretty dumb question. Is there a way for me to allocate more resources to Puma so it doesn't need to restart itself so frequently? I'm currently only using around 25% of the server's memory.

Thanks for the help

[Rails] how to retrieve an aray of only specific attributes in rails 2.3

Ruby on Rails

I have a scenario where I need to retrieve an array of specific
attributes from a table. I have a TransportAttendanceBlock table. In the
table I have blocked(boolean) and blocked_date attributes. From a
controller I am fetching this table by passing params of date and
boolean value.

Controller code:
@blocked_date =
TransportAttendanceBlock.by_blocked_date_and_blocked(@today,1)
Model
named_scope :by_blocked_date_and_blocked, lambda{|date,status|
{:conditions=>
{:blocked_date=>date.beginning_of_month..date.end_of_month,
:blocked=>status}}}

Here in the controller I am getting the entire objects of
TransportAttendanceBlock table.
But I need to just pass any array of dates only in the @blocked_date
variable as json.
So how do I extract only blocked_date attributes and assign it to
@blocked_date variable. Please help. I am using rails2.3 and ruby 1.8.7

Re: [Rails] Why is the behaviour of ActiveRecord method_missing different between rails 3.2 and 4.0 ?

I have been working on updating a rails application to 4.0 and spent some time getting to the bottom of why it wasn't working.

What I found was, if a model has a method_missing definition then it is called instead of any accessors. This causes any model set-up to fail.


As far as I am aware, the accessors for attributes have always been generated using method_missing (the method missing hook then actually defines the accessors, so after that method missing is not used).

What might possibly have changed is when this gets triggered. Regardless if you do override method_missing it's a good idea to call to the superclass as other aspects of active record may rely on this.

Which bit don't you know how to do?
Where to put the code?
How to determine the id of the row?
How to find the record in the second table?
How to change the value in the second table?
How to save the value in the second table?
Something else?

But before that the more important question is whether you should have
a belongs_to, has_many (or similar) association between the tables so
that rails will do most of the work for you.

That means you can use it as a means of saying "All the methods defined below are module functions":


Module M

def foo
end

module_function

def bar
end

def baz
end

end

and so you can then call M.bar and M.baz, but not M.foo.

This is identical to:

Module M
def foo;end
def bar;end
def baz;end
module_function :bar, :baz
end

It is *also* identical to:

Module M
def foo;end
def self.bar; end
def self.baz; end
end

So, "restarts itself"? Do you have any idea why? I've never seen any
of my own Puma instances spontaneously restart.

Have you looked in the system logs for anything relevant? Is there
a mismatch between you-the-user-manually-starting-it and the user
that the process is normally running as/restarting as?

What Ruby are you running?

Re: [Rails] Re: Re: Concatenate two arrays

Ruby on Rails

The arity should be -1, not 2. See the docs here: http://www.ruby-doc.org/core-1.9.3/Method.html#method-i-arity

I read the pickaxe book about three years ago, when I first started with Ruby 1.9.2. It was quite beginner friendly, and very useful. I haven't read more recent editions.

[Rails] Puma fails when it restarts itself

Ruby on Rails

I'm having an issue with Puma, it fails when it tries to restart itself. When this happens it kills all the Puma processes, resulting in nginx delivering a 502 Bad Gateway to our users. I'm able to start, stop & restart it with my /etc/init.d/puma script (it runs /usr/local/bin/run-puma),  it just has issues when it restarts itself. The puma.log file doesn't show anything just useful for troubleshooting, just

Puma starting in single mode...
* Version 2.5.1, codename: Astronaut Shoelaces
* Min threads: 16, max threads: 32
* Environment: production
* Listening on unix:///home/deploy/app/shared/sockets/puma.sock

and my workers. Any help would be greatly appreciated.

Also - i have whats probably a pretty dumb question. Is there a way for me to allocate more resources to Puma so it doesn't need to restart itself so frequently? I'm currently only using around 25% of the server's memory.

Thanks for the help

Thanks Colin!

The "issue" was on HTML code: each faulty HTML tag was being wrapped

I have added "display:inline-block" in the CSS class and everything is
working perfect now.

Hi Colin and Dheeraj,

First off thanks for your help. It is actually quite funny, I ordered
that exact book a few days ago :). I also worked through Chris Pine's
book, which was very nice. I always think i get the ideas, practice the
items that they show, but when it comes to solving problems I freeze up.
Guess it will come with a ton more practice and reading.

thanks for taking the time to help

Hello again ruby community!

I just learned how to add two arrays(I know, i know).

My program looked like this

array1=[1,2,3]
array2=[4,5,6]
array_sum=array1+array2

I thought pretty simple stuff, they are combined. However, now i am
looking to define that code as a method and I do not understand how to
create the correct number of arguments, so when the method is called
back it gives me my array_sum.

I have been trying many different variations, but it has now come down
to I am not sure if my defining is wrong or my code in the method is
incorrect.

I want to say it is something such as

def please_work()
array1=[1,2,3]
array2=[4,5,6]
array_sum=array1+array2
end
puts please_work(array_sum)

i ended up fiddling around and getting it to output [1,2,3,4,5,6], but
my syntex said i did not have the correct number of arguments. Also,
sometimes i get array_sum is not a defined variable. If I am defining it
in the method, shouldn't it be defined if i call the method again?

thanks taking a look at my question

Re: [Rails] Concatenate two arrays

def array_sum(array1 = [], array2 = [])

end

array_sum([1,2,3], [4,5,6])

I thought pretty simple stuff, they are combined. However, now i am

I have been trying many different variations, but it has now come down

I want to say it is something such as

puts please_work(array_sum)

i ended up fiddling around and getting it to output [1,2,3,4,5,6], but
my syntex said i did not have the correct number of arguments. Also,
sometimes i get array_sum is not a defined variable. If I am defining it

Using Firebug in Firefox you can inspect the css and see what is going
on. Also inspect the html and see what has changed there.

[Rails] Error layout

Ruby on Rails

Hi all,

I have created a form to insert new records (see "Selección_001.png")
with two mandatory fields ("name" and "surname") but if I try to insert
a blank record (so it is invalid) I get the two errors (that is correct)
but the page layout is modified (see "Selección_002.png"), which is not
correct.

As you can see "Name" label, "name" text box, "Surname" label, and
"surname" text box are moved each one to a new line (which is different
from to original layout)

I have tried to delete ALL css files on the folder but without success
("Selección_003.png"), the red color disappears but the layout is still
modified ;-(

Does anybody know what file I have to update to avoid this change in my
layout?

Thanks!

Jorge

Very likely a problem with routes.rb. Post it here (after removing
all comment lines, we don't need to see those).

[Rails] RIA4: Having an issue with my sign_in_as! helper method I've defined in my integration tests

Ruby on Rails

I'm having a frustrating issue where my sign_in_as! helper will not fill out the password in my seeds_spec test. However all other integration tests using the helper still pass which is very confusing for me.

I put a call to sleep in for the method, and ran the test with webdrive to fill in the password manually, and the test completed as it should.

I tried different solution as suggested by folks for changing routes.rb but not getting right one.. 
Can anyone tell what's wrong..??
