Ruby on Rails

Hi all

I am working with the paypal recurring gem and rails 3.

I am subscribing different plans for a demo site. with "Basic" and "Premium" plans.

I am doing a refund process for test.


def refund_payment
    ppr = PayPal::Recurring.new({
      :profile_id => self.paypal_recurring_profile_token,
      :transaction_id => "#7RX73297E7023873T",
      :reference      => "1234",
      :refund_type    => :full,
      :currency       => "USD"
    })
    response = ppr.refund
    raise response.errors.inspect if response.errors.present?
    response
  end

For profie id it gets the profile id from the table for each transaction. But incase of transaction id there are no transaction id in response while getting a payment to paypal.
I just hardcoded the transaction id from the last transaction from the website. But it showing error.

[{:code=>"10004", :messages=>["Transaction refused because of an invalid argument. See additional error messages for details.", "The transaction id is not valid"]}]

You can't - the call to escape_javascript happens server side, whereas
the value of page will only be known client side, at the point where
the user clicks on something. You could load the content via ajax

I had a hunch that reinstallation or trying a different port weren't necessary. I probed a bit more and found some processes named netsession_win.exe in Task Manager. I stopped these. I then went on to uninstall some software named Akamai* from Add/Remove programs, and now all is well.

Tried a different port ?
eg: rails s -p 9001

Hi All,

A question on using javascript within a view to render a partial. Been
struggling wit this for a bit.
I've multiple partials in my views and I want to replace them within a
specific div, how do I get this variable 'page' within the
escape_javascript and replace it with 'reviews' so I can render the
other pages (Such as specials, gallery, etc) within that div.

Thanks. Appreciate the help!
Below is the code snippet.

<script type="text/javascript">

$(function(load_content) {
$("#reviews, #specials, #gallery, #location, #contact,
#about").click(function() {
var page = this.id;
//alert (page);

$.pageslide.close();
var content = "<%= escape_javascript(render(:partial =>
'reviews')) %>";
$("#content").html(content);
})
})
</script>

Hello All --

I am using jruby 1.6.7.2 with rails 3.2.11 to create a brown bag for
several other developers. I cannot get the migration to work to save my
life...

In my database yaml file I have the following:
---
development:
adapter: jdbc
driver: oracle.jdbc.driver.OracleDriver
url: jdbc:oracle:thin:@localhost:1521:xe
username: brownbag
password: brownbag
pool: 500
---

When I run:
---
rake db:create --trace
** Invoke db:create (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:create
---

when I run:
---
C:\temp\brownbag\my_workout>rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:migrate
rake aborted!
Table schema_migrations does not exist
arjdbc/jdbc/RubyJdbcConnection.java:126:in `columns'
c:/temp/brownbag/gem_home/gems/activerecord-jdbc-adapter-1.2.5/lib/arjdbc/oracle/adapter.rb:358:in
`ora_columns'
c:/temp/brownbag/gem_home/gems/activerecord-3.2.11/lib/active_record ...
----

If I switch my database.yml file to the original slite3 that rails auto
generates all is fine.

If I place the following in irb:

---
require 'rubygems'
require 'activerecord-jdbc-adapter'
require 'active_record'
require 'active_record/version'

a= ActiveRecord::Base.establish_connection(
:adapter => 'jdbc',
:driver => 'oracle.jdbc.driver.OracleDriver',
:url => 'jdbc:oracle:thin:@localhost:1521:xe',
:username=>'brownbag',
:password=>'brownbag'
)

c = a.connection
ct = "CREATE TABLE example (id INT, data VARCHAR(100) )"
d = c.exec_query(ct)
---

The table is created as expected!

Help!

Thanks,

Cris

I am unable to install RoR on a VPS running RedHat Linux with 512 MB. When I run "make" and "make install" I get the following output/error below. What can I do to resolve this memory problem? 

I have a synchronization problem that I am not sure how to solve in Ruby/Rails. I have a mental model of what I need to do and how it should work, but can't find the way to do it in Ruby/Rails. (I've learned all about Mutexes and transactions and lock! but despite my research, am still stuck). I come from the kernel programming world, so I may be framing this incorrectly. 

tl;dr Yes, you /can/ even if Colin's advice is good (AND I agree with him!)
customer = Customer.new(other_attributes_here) {|c| c.id = user.id }
customer.save

Well, what you can't do is use "mass assigment" to set the id of an ActiveRecord model.

You can, however, set the id on a new record and it will be honored if the database doesn't forbid it. (For example, if that primary key value already existed.)

There's even a block form of ActiveRecord.new that passes in the newly initialized object.

customer = Customer.new(:name => user.name) {|c| c.id = user.id }
customer.save(:validate => false)

Since you already have a "user_type", it seems like you're at least halfway to being STI (Single-Table Inheritance) anyway.

Couldn't you have:

class Customer < User
end

Then you'd have a `type` attribute (column) in the users table which would hold the class name represented by that row of data. (which could be "User" or could be "Customer")

Then you can say:
r = User.find_by_name('ccc')
and r will hold an instance of the Customer class.

I'm migrating an app from rail 2 to rails 3 and hitting several instances of strings that need to be code html_safe to prevent the default processing from breaking the html.  Are there tools or techniques to easily identify all such instances in the source code or is the only option to discover each instance one at a time?  Thanks

So your system is basically broken. Seriously, I think it's time for an
OS reinstall - preferably with some version of Linux :-)

Unless you can find someone who knows Windows who can help
you troubleshoot this, but that's not me; sorry!

Best of luck, though.

Are you sure you want to do it that way? It may well be simpler to
keep one table with flags to indicate the type of the user.
Alternatively you could use STI (though again this may be more complex
than just flags). Also there is the cancan gem that allows users to
have various roles (user and customer in this case). Remember that
you can have multiple relationships between the same tables with
different association names for the different cases. Also remember
that you can have self-referential associations so that if you want
relationships between users and customers that can still be done even
if they are in the same table. See the Rails Guide on ActiveRecord
Associations.

If you can't see how this would work post the proposed relationships
between users, customers and the rest for suggestions on how to
achieve the same thing with a single table.

I don't think you use the assets part of the path in Rails 3.1+. Try it with just /videos/video.mov and see what happens then.

I am converting/migrating an app from rails 2 to rails 3.  Along with other things that must be changed, I am encountering scattered instances of string literals and strings returned by helpers in templates that are being automatically html escaped on rails 3.  Are there any tools or techniques to identify and perhaps automatically correct these instances or is continuing to find them piecemeal the only way to proceed?  Thanks

I'm migrating the tables with existing data
I've users table and all other tables contains the user_id column and
now i need seperate the users into two (users & customers) tables
So i need to migrate the new customers table with existing users records
where the user type with customer

I need to create a customers table and set the id of users records with
user type as customer,
which will be easy instead of migrating many of other tables(which is
used only by customers) by checking every record with user's user type
and assign the new id of customers table.

My tables should looks like

users table:

id | name | ...
------------------------------
1 | aaa | ...
2 | bbb | ...
4 | ddd | ...
6 | fff | ...

customers table

id | name | ...
-------------------------------
3 | ccc | ...
5 | eee | ...
7 | ggg | ...

When i'm migrating users existing data, I can't assign the id of user as
customer's primary id

In my migration file

def up
create_table(:customers) do |t|
t.string :name
end

User.joins(:user_type).where(:user_type => {:type_name =>
'customer'}).find_in_batches(:batch_size => 100){ |users|
users.each {|user|
customer = Customer.new
customer.id = user.id
customer.name = user.name
customer.save(:validate => false)
}
}
end

Also tried

Customer.create!(:id => user.id) instead of save method

And

INSERT INTO customers(id, name) VALUES("#{user.id}", "#{user.name}")

Finally all ended with same error

Error: Called id for nil, which would mistakenly be 4 -- if you really
wanted
the id of nil, use object_id

Is this correct?

Is there any way to assign the primary id ?

Please anyone explain how to do this?

I tried running msconfig, chose selective startup, then rebooted. Thereafter, I could browse with IE, Firefox, but once I stop browsing for a while, and then try again, they fail again. No, I do not have a firewall. I'm very concerned as I have developed the rails app on the machine and desperately need to get the app back up and running. Can you tell me the name of the process that runs Webrick on Windows?

?! It's been years since I've touched a Windows machine, but that
sounds like your system is totally b0rk3d. Do you have a firewall
of some sort that might be affecting networking?

Try using basic networking tools like ping, traceroute, telnet, etc.;
if your system crash was extremely ungraceful, you might have an
OS reinstall ahead of you...

Good luck,

Today i've tried to update a site because of the latest security
problems.
But this older app breaks as soon i install anything newer than 2.3.5

When switching to 2.3.6 or later in environment.rb (same with the latest
2.3.16) everything gets rendered as text/plain so all i see is the html
source (which is supposed to be UTF-8) as ISO-8859-1.

I'm also not seeing any errors in the logs nor on console.
At most i get some deprecation warnings about rake tasks in
vender/plugin.

What could cause such a weird behavior?
Does anyone know?

But you don't need .includes,
@test = Product.all
will work fine (though I would prefer @products =Product.all since
that is what they are).

If you inspect @test you will not see the prices, but as soon as you
ask for the prices it will fetch them. Such is the magic or Rails.

I am sure readers here are bored with me suggesting to beginners that
they work right through a good tutorial such as railstutorial.org,
which is free to use online, but it is definitely a good idea as it
would give you a good introduction to the basics of rails. Also look
through the Rails Guides.

For some reason I am rarely thanked for offering this advice. :(

[1] http://stackoverflow.com/questions/13061836/getting-this-error-in-rails-actionviewtemplateerror-code-converter-not-fo

Hello,

I'm trying to join 2 tables with ruby on rails 3.2.

rails generate model product name:string
rails generate model price product_id:integer price:integer
date:datetime

product.rb:
class Product < ActiveRecord::Base
has_many :prices
end

price.rb:
class Price < ActiveRecord::Base
belongs_to :product
end

What is the most efficient way to get all products including the latest
price into the View.

Some tries didnt work for this:

@test = Product.includes(:prices).all
I didnt find anything about the prices in @test.

Thanks for help!

First have a look at the docs and then come back with your best atempt
and explain what does not work about it.
However, are you sure you want to use select_tag rather than using
form_for and f.select? There are occasions when using form_tag and
select_tag is appropriate but if possible then use form_for.

If you have not already done so then work right through a tutorial
such as railstutorial.org which is free to use online and will show
you the basics of rails.

First don't store the total in the database, provide a method of the
model called total which works it out when you need it. If you store
it then you add all sorts of complications making sure you keep the
total correct when you change the other fields, and there is no need
to add the complexity.

Second, if you want the total and tax value displayed on screen as
they are entered then that must be done by javascript so that is not a
RoR issue. Some tutorials on javascript and probably jQuery are in
order.

I don't understand what you mean by the last sentence.

If you have not been able to work right through a tutorial so far then
I suggest railstutorial.org which is free to use online. There is
nothing like actually working through a tutorial, doing the exercises
and so on, to get a grasp of the basics.

Being new to rails and ruby I'm a bit lost.

Have a data entry scaffold, Details, which has name, string,
cost1:integer cost2:integer cost3: Total:integer
The user inputs puts a value into each of 3 fields.

The totals field should ideally be automatically updated as each value
is entered or changed. Then Save stores all 4 values into the database.
One of the values cost3 should display a tax value of 10% of that
particular entry beside the entry.

Is this possible to do this or should I have something like a cart and
display the calculations in that?

I have read the Agile Web Development books, Enterprise Recipes,
Advanced Rails, Why's Poignant, Head First Rails which is for rails2 so
some scripts fail.
None explain how to do some of the more simple things like the above or
taking a value from a select list and using it to update a field in
another view.
I've been searching for days with no luck,
Thank you in advance

If you are new to rails there are probably many other basic features
that you are not aware of. I suggest you work right through a good
rails tutorial such as railstutorial.org, which is free to use online.
That will introduce you to the basics. Also look through the Rails
Guides, the one called Active Record Validations and Callbacks should
cover what you are looking for. Also look through the others.

Thanks, Jordon. I already tried that, there's no Webrick or Ruby process listed.

hi dude i'm also new to ror, two days back i struggled for the same problem but in my case when i select an item from dropdown in my view. based on the selection another dropdown in the view should be update automatically without touching database...

Hello everyone,

Hi Hassan,

There was a sudden power outage and therefore Webrick couldn't be
shutdown gracefully. On machine restart, I got the exact same error as
Gordons, however, my Ruby is 1.8.7 and I'm on a WinXP machine.
Additionally, I found that none of my browsers (IE/Firefox) can connect
to any website.

I would be thankful if you can explain step-by-step how to find out
whether another instance of Webrick is running and how to shut it down.
Of course, I tried browsing to 127.0.0.1:3000, but my browsers have been
affected, so the page cannot be displayed.

Thanks in advance.
