[Rails] insert problem with rails3

Ruby on Rails Tuesday, January 31, 2012

tran =Transaction.select("transactions.id,transactions.user_id,transactions.branch_id,transactions.customer_id,transactions.membership_type_id,transactions.bill_amount,transactions.bill_date")

treport = TransactionReport.new

puts "from report"

tran.each do |u|

bs = TransactionReport.new(

:user_id => u.user_id,

:branch_id => u.branch_id,

:transaction_id => u.id,

:customer_id => u.customer_id,

:membership_type_id => u.membership_type_id,

:bill_amount => u.bill_amount,

:bill_date => u.bill_date

)

bs.save

Here the object creation will happen in loop so this will create new object for TransactionReport with each insertion. How to avoid this in rails3.....?

Thank you

It's only failing to install the docs. Either add the option to gem
install to skip the docs, or do the actual right thing and put the gem
in your Gemfile and use bundler to install. That will automatically skip
installing the docs. The docs you probably won't use anyway.

[Rails] Devise with Rails 3

Ruby on Rails

Hi All,

Im using devise with rails 3.

My requirement in this is,

There are two scenarios.

1. User send reset password for their email id.

2. Admin send reset password for the user mail id, where the user is not
active. When this scenario is generated, the reset instruction mail
should be delivered to the admin email id and not to the actual user
mail id.

This is tricky but this is what my requirement is.

Can this be done in devise?
Or is there any other possibilities?

Can anyone share your thoughts on this?

Regards,

For what you describe, that should work. As a note, games can have
only one user. If that was not your intention, look at has_many
through and has_and_belongs_to_many.

[Rails] Unable to run rake db:create:all

Ruby on Rails

I am able to create databases (development, test, and production
databases) as follows
.................................................................

But when I try to create same databases using the command
'rake db:create:all', I am getting an error massage saying 'FATAL:

databases are created.

And also after creating databases as shown above, I created migration

Can you please help me why 'rake db:create:all' is not working?

[Rails] [Job] Washington, DC (downtown) high traffic, high performance news site seeking perm and contract RoR talent (no remote)

Ruby on Rails

I took some time to search and find if job postings are acceptable here and what format the community seems to prefer. Hope this is ok.

Confident you can design/build for high performance RoR web infrastructure that serves tens of thousands of users concurrently? Users accessing massive amounts of data?

Look into the future. You came into a world class software company three years ago to build elaborate, high traffic web products for a global media powerhouse. These are not shopping or informational websites, but complex and detailed business services delivered over the web to the most sophisticated customers. You've grown with the team and can now continue to thrive in one of the world's most advanced software development organizations or parlay the experience into a new direction.

This company offers 4 weeks vacation to start, free health insurance for your whole family, 50% 401k match, and very healthy comp among other benefits. They have carefully built a highly diverse and high performance software development organization. You will emerge a much better developer in a few years. In this company software performance is more important than anything else. This is not a punch the clock and wait for a 3% annual raise job. This is a "let's make it better than any other company in the world can" job.

The tech: we are looking serious experience on high traffic RoR customer facing sites.

Bonus for skill in Java.

Web services creation experience with SOAP or REST.

Design with HTML, CSS and JavaScript (JQuery)

It's an Agile development environment.

Rails often is. For example, a while back I was trying to do a simple

that duplicated a lot of what Rails was doing behind the scenes.
Correct solution? Don't. Just let Rails do it. No problem. Now I

That's normal behavior, it frees up memory on the server that's just
sitting around doing nothing. That's also how Passenger works by
default. It "intelligently" spawns and kills off instances.

But rest assured, if your application has more users accessing it, it
won't be suspended.

Re: [Rails] Why Heroku so slow?

Ruby on Rails

I believe this to be the root issue. That's why things like reserved instances at AWS are sometimes better because they stay up all the time.

I understand the Google App engine is the same way. Makes it unusable for Grails apps because spinning up the JVM is so slow the app startup even times out causing no load at all.

I can't be sure, but.. AFAIK

Does this only happen the first time the page is loaded?

Heroku unloads applications. Both when it's deployed, and after
periods of inactivity. The first load after it's been unloaded is
always slow.

Re: [Rails] Why Heroku so slow?

Ruby on Rails

Heroku put you app into a sleep mode when it's no accessed in a certain amount of time. Sometimes when no one visited you application in the last several minutes and whoever access it, the app will bootstrap, this process can take several minutes. But this only occurs in the first request, subsequents request should run fast.

Re: [Rails] Database level authentication

Ruby on Rails

I appreciate what you're trying to do. I've been a dba in the past and
have built apps using database credentials in the past.

But this is a mistake. They key to being successful with rails is to
leave behind the ways you did things before and embrace 'the rails
way'.

ActiveRecord using a single connection string to connect to the
database -- it's in the database.yml file in the /config directory.
Having it somehow use different credentials based on the user would
make things much more complicated than need be.

My advice -- forget about how you did things before and embrace the
powerful and fast tools that rails provides to do things.

In this case, use 'device' -- it's what almost everyone else uses and
you'll thank yourself later for doing so. If you proceed with the way
you're going then later on you'll kick yourself and wonder what the
hell you were thinking.

Best of luck.

[Rails] (de)serialization problem with rails 3.2

Ruby on Rails

I have a custom serializer object that I use for an attribute of
ActiveRecord as presented in this article:
http://www.edgerails.info/articles/what-s-new-in-edge-rails/2011/03/09/custom-activerecord-attribute-serialization/index.html

If I assign a value to that attribute with a form (in my case a nested
form), I don't get the deserialized value in the params hash as it used
to be with Rails 3.1, but now I get a serializer struct that contains
the custom serializer class instance and the deserialized value.

Does anybody know whether this is intentional, or is it just broken and
I have to work around that until it gets fixed...?

Sounds like you want DB to tell you the roles people play and what
permissions go with those roles.

good day try gem update

Actually, I see a similar problem on a directory where I have installed

$ rails new --edge

inside a gemset. What I have to do there is always use `bundle exec`
like this:

$ bundle exec rails console
$ bundle exec rails generate ...

For reference, this is the set-up described here

Have a look in log/development.log to give you some clues as to what
is happening.
If you still can't work it out have a look at the Rails Guide on
Debugging. In particular see how to use ruby-debug to break into your
code and inspect data and follow the flow to see what is going wrong.

I don't know much about Windows, most Rails developers use Mac or
Linux (often Ubuntu). However first you must check that your mysql
server is working, presumably there is some way of accessing mysql
from the command line to check it and to setup users and so on.
Assuming you have already done this then setup the database details in
database.yml and all should work.

Personally I advise people not to do Rails development Windows, but
others do manage this. Either use a virtual machine running, for
example, Ubuntu, using VirtualBox or VMWare or set your PC up to dual
boot Windows and Ubuntu, which is very easy.

If you must use windows then I believe using railsinstaller is
considered the best option at the moment.

Other than the above, if you have further problems while using
Windows, I am afraid I will have to leave it to others to help.

Do you mean you are trying to install a mysql server on your pc, or

Also tell us which operating system you are using.

[Rails] Instantiating a new object with a template, through an association

Ruby on Rails

class Project < ActiveRecord::Base
has_one :template
end

class Template < ActiveRecord::Base
belongs_to :project, foreign_key: "project_id"
end

When you create a new project I'd like you to select the template from
a collection of existing templates (created by an admin).

The new project.template should have all of the template's attributes
(clients, tasks etc) and these should be editable without affecting
the original template (a completely new instance).

My difficulty has been in moving all of the template's params through
the select input from a form.

My current (very poor) attempt at the form looks like this:

= simple_form_for @project do |f|
#### project stuff here #####
= simple_fields_for "project[template_attributes]",
@project.build_template do |project_form|
= project_form.input :title, collection: @templates

There is actually a way to just query the database.

You haven't said what database you're using, but the procedure should
be more or less the same once you figure out how your specific
database stores things.

In case of MySQL, you would basically have to establish a connection
with the database "mysql" from some ActiveRecord model (using
"establish_connection", search it at http://api.rubyonrails.org/),
then make sure your ActiveRecord model connects to the "user" table
(singular! so use self.table_name="user" in Rails 3 or set_table_name
in Rails 2) witin that database. Then you can just use a method like:

Rails 2.x
def authenticate(login, passwd)
self.first(:conditions => ["Login=? and Password=PASSWORD(?)",
login, passwd])
end

Rails 3.x
def authenticate(login, passwd)
self.where("Login=? and Password=PASSWORD(?)", login, passwd).first
end

This is completely untested and it's an authentication method I'm not
too fond of, but this is more or less how you could get it done.

Best regards

The only way I can think of doing that is to attempt to connect to
re-connect to the db when he logs in, using his credentials, and see
if it successful.

register in the below link to get your api key

http://www.google.com/recaptcha

put below line in your gem file

gem 'recaptcha', :require => 'recaptcha/rails'

put you api keys in config/environment.rb filr

ENV['RECAPTCHA_PUBLIC_KEY'] = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
ENV['RECAPTCHA_PRIVATE_KEY'] = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

you can verify recaptcha conditions in controller methods by verify_recaptcha varible

ex:-

if !verify_recaptcha
#do operations
end
