[Rails] Re: remote_function - how to include a id of current model

[sami]

when you use remote_function the :with option actually expect
javascript code.
in your code remote_function helper is assuming "word_id + '=' + #
{word.id}" is
a javascript code.
so you can do any of the following two things
   :with=> "'word_id='+document.getElementById('word_id').value" where
word_id will be the id of that element
   or
   you can send it to with the :url option

Do you have a database table called 'platforms_weburls' with 'platform_id'

[Rails] invalid pointer in libxml xmlFreeNodeList

[Simon Macneall]

Hi,

Not sure if there is a better place to post this. The libxml-ruby mailing  
list doesn't have much activity.
We are getting occasional errors on our production box, that I can't  
duplicate in testing. It's not even reproducible on the production box  
with the same inputs, but I've managed to track down (via a lot of print  
statements into the Apache logs) that it is dying during the save of one  
of our models, and it appears to be during the native memory cleanup of  
libxml-ruby.

The following is appearing in the Apache error.log (we are running  
Passenger)


*** glibc detected *** Rails: /var/www/Liftronic: free(): invalid pointer:  
0x08884499 ***
=== Backtrace: =
/lib/libc.so.6[0x2b5e6e225cb8]

/usr/lib/libruby1.8.so.1.8[0x2b5e6d608dfa]
/usr/lib/libruby1.8.so.1.8[0x2b5e6d602cf0]

The model that is being saved has a one-many relationship with another  
model which has XML attached to it, which is being processed using libxml,  
but I can't see anything wrong in any of that code.

We are running libxml-ruby 1.1.3 and 2.6.32.dfsg-5ubuntu4.2 of libxml2,  
running on Ubuntu 9.04.

Does anyone have any suggestions on how to proceed with fixing the issue?


Cheers
Simon

[Rails] Order of Join table

[Rilindo Foster]

That was fun.

Due to some mix-up, I ended up having to rename my models. At any event, I 
managed to fix everything, except that I kept getting this message when I 
attempted to delete an entry:


ActiveRecord::StatementInvalid (Mysql::Error: Table 
'development.platforms_weburls' doesn't exist: SHOW FIELDS FROM 
`platforms_weburls`):

The way I setup my module is that platforms and weburls are connect via the 
has_and_belongs_to_many association. So I was expecting for the rails up to 
look it up like:

weburls_platforms.

But no. :(

This is the second time that happened to me and in both instances, I ended up 
having to rename the tables to get the models working (of note is that I had to 
redo the models in the first open as well - also a hbtm relation - same base 
table). Am I missing someplace as to how rails put together the join table 
names? And is there a better way of addressing it? My current tables don't look 
very consistent. >:(

Yup! You probably want two routes:

map.connect 'posts/index/:page',
:controller => 'posts',
:action => 'index',
:requirements => {:page => /\d+/ }

map.connect 'posts/index',
:controller => 'posts',
:action => 'index',
:page => nil

Or more succinctly:

map.with_options(:controller => 'posts', :action => 'index') do | 
post_index|
   post_index.connect 'posts/index/:page', :requirements => {:page => / 
\d+/}
   post_index.connect 'posts/index', :page => nil
end

You're describing client-side behavior. That means "JavaScript"  :-)

(OK, alternatively, you could use Flash or a Java applet, but ...)

[Rails] Re: Route error to Admin namespace

[Freddy Andersen]

This works fine for me in jruby:

map.namespace(:admin) do |admin|
  admin.resources :clients
  admin.resources :options, :has_many => :widgets
end

Does this not work?

Make sure its above the default routes...

[Rails] how to understand Ruby/Rails code? (noting various mixins/includes) Is there a tool to assist here?

[greghauptmann]

Hi all,

Every rails app / gem / plugin I download the code for I seem to spend
a good deal of time trying to make sense of the code due to the way
Rails / Ruby is very dynamic.  There are various code files that are
really just ready to be "mixed in" to other files (e.g. with the class
methods & instance methods ready to go).  Just trying to make sense of
the final object structure and where methods resides seems to be a
challenge.  The latest one I've been looking at are things like
AuthLogic and Paperclip.

QUESTION 1:  Is there a tool that could assist here?  I'm thinking of
one that could do things like walk the code base and then:

* Give a hierarchy structure where various files methods are loaded
into which objects

* Given sample walk throughs of methods hit in which files for a given
controller/action (e.g. like how the java IDEs can auto-sequence
diagrams)

* Perhaps something that analyses code and then added comments to the
various files highlighting where that files methods will reside in
terms of the final object structure.

QUESTION  2: Should of nothing be available for the above, and tips/
tricks people have re understanding a new plugin/gem codebase?

thanks

Re: [Rails] Route error to Admin namespace

[Paulo Coutinho]

Hum. Ok.

The last solution doesn't work, so i think that i'll have to make a route to
each controller :(

Do you make one route by controller? Can you post an example about how i can
redirect all from "admin/clients" to correct controller/action/id ?

[Rails] captcha

[RubyonRails_newbie]

Hi all,

I want to implement a captcha on my register page to help weed out any
'non-human' visitors.

I was told to check out http://expressica.com/simple_captcha/ but the
site isnt responding.

Does anyone have any other reccomendations that are tried and tested &
successful?

Many Thanks

I have an application with something like 20 controllers and make all
routes explicit for each controller.

You could probably do

map.with_options(:namespace => "admin") do |admin|
 admin.connect ':controller/:action/:id'
end

[Rails] routing requirements quick question

[Clarice]

Hi everyone, first e-mail here :)

I have the following in my routes.rb file.

map.connect 'posts/index/:page',
:controller => 'posts',
:action => 'index',
:requirements => {:page => /\d+/ },
:page => nil
end

Does :requirements => {:page => /\d+/ } mean that if the :page
parameter is empty this rule should not work?

Thanks in advance!

Hi,

[Rails] Re: hpricot on mac os 10.6

[Rick]

Not sure about why-hpricot but hpricot (0.8.2) runs under ruby 1.9.2

$ ruby --version
ruby 1.9.2dev (2009-10-18 trunk 25393) [powerpc-darwin9.8.0]

As you can see from the above, I'm running ppc / osx 10.5.8 so no
guidance specific to intel/10.6.

You might try ...gem install hpricot

Also, don't know if you're aware but here are some links from the
hpricot README:

-
First, here are all the links you need to know:

* http://wiki.github.com/hpricot/hpricot is the Hpricot wiki and
  http://github.com/hpricot/hpricot/issues is the bug tracker.
  Go there for news and recipes and patches. It's the center of
activity.
* http://github.com/hpricot/hpricot is the main Git
  repository for Hpricot. You can get the latest code there.
* See COPYING for the terms of this software. (Spoiler: it's
absolutely free.)

If you have any trouble, don't hesitate to contact the author. As
always, I'm
not going to say "Use at your own risk" because I don't want this
library to be
risky. If you trip on something, I'll share the liability by repairing
things
as quickly as I can. Your responsibility is to report the
inadequacies.

good luck

First off, you could just include word_id in the :url options. If you do want 
to use :with then the value needs to be a fragment of javascript that evaluates 
to an appropriate bit of query string - I've got some examples here:

[Rails] remote_function - how to include a id of current model

[analogue40]

Hi all,

Hope someone can help me out with this weird problem, I'm sure it's
something simple.

All I want to do is send the ID of the current model from the view
into the controller via a remote_function call

basiclaly I'm adding a word to a list using a check box:

check_box_tag "list_ids[]", list.id, list.words.include?(word),
{ :onchange => remote_function(:url => { :controller =>
"list", :action => "add", :id => list.id }, :with => "word_id + '=' + #
{word.id}" ) }

The part which isn't working is specifically this:

:with => "word_id + '=' + #{word.id}"

If I remove it the code works but obviously I need that word.id in the
controller so I know which word to add to the list.

Thanks in advance!

Dave

Re: [Rails] Re: link_to_function or button_to_function memory usage

[Chris Habgood]

It is all ajax and it never complete out.  It looks like it is in a loop
generating each partial over and over again.  when it finally times out it
says it cannot allocate memory.  Is there any way around this so I do not
have to make ajax calls for those 2 actions as it is not really necessary?

yes - it is generating the partials and including them in the page -
if you look at the source of the page you'd see something like

Element.update('showcontact', 'long html string here')

[Rails] Re: link_to_function or button_to_function memory usage

[Me]

ok maybe not enough detail.

When a user selects a person from a drop down selection  it shows the
user below with 2 options, to edit the user or delete the user

<%= link_to_function 'Edit Contact' do |page|
   page[:showcontact].replace_html :partial => '/contacts/
ajaxshoweditcontact'
 end %>

Inside the ajaxshoweditcontact there is this link top cancel the edit:

<%= button_to_function 'Cancel' do |page|
  page[:showcontact].replace_html :partial => '/contacts/
ajaxshowcontact'
end %>

Is it generating the partials for both links when I go to the show
page above?

You should be able to generate them yourself - run rake doc:guides
from a rails app (it should put the output in doc/guides) or clone the
rails source and run the doc task from there (if you want the most up

Ruby uses both = and => as assignment operators, depending on the

[Rails] view to pdf with pdf::writer

[isabel]

Hello,

I would like to send a view to a pdf file.
To do that I have choosen the tool "pdf::writer", I have tested it and
I found a problem when I do:

 pdf.text render :layout => "my_layout"

it sends the whole html code to the pdf file.

How could I send the result of the html file to the pdf file?

Thanks and let me know if you do not understand it.

Isabel

[Rails] Re: Business logic against model records

[Andrew Edwards]

I had be contemplating a STI solution but it still involved account
types in the database.

I can see a number of problems being solved with your suggestion,
hadn't thought of it this way. My initial thought though is that
potentially there are around 10-15 account types, would this start to
look ugly with so many models extending this single feature?

I've also got to check how STI influences AR performance. Potentially
I've got around a million records in the accounts table as each
product will have multiple accounts based on batches. Each time a
delivery arrives it creates a new batch for that product which in turn
creates a new account(s).

Every product has around 10 accounts, and every product creates a new
set when a new batch of stock arrives, approx. 24 times a year. So you
can see each product may spawn around 240 accounts a year at worst
case scenario. It's a little heavy but storage is cheap and it allows
a fantastic level of visibility of inventory progress and history.
Just got to watch performance. Indexes and caching will likely be
first ports of call.

Once an account reaches zero it is essentially dead and no longer
used, however I need to keep it on hand for audit trail purposes. I
will likely implement an accounting period function which archives
older accounts out of the live accounts table.

[Rails] Business logic against model records

[Andrew Edwards]

Hi,

I have a small architectural decision to make.

I'm modeling double entry accounts to handle product inventory. An
account is a combination of a product, storage location. Accounts also
have sub-types such as "Available" and "Reserved".

Therefore it is possible to have more than one account for the
combination of ProductA and LocationA, one account with type
"Available" and another with type "Reserved". Accounts contain entries
which add or subtract against the account balance. Entries then belong
to transactions which ensure every addition to one account has a
subtraction from another, essentially that product inventory is
preserved.

class InventoryAccount < AR::Base
   belongs_to :inventory_account_type
   belongs_to :product
   belongs_to :storage_location
   has_many :inventory_account_entries
end

My issue is with InventoryAccountType, currently this is a AR model
and a simple database table holding around 10 rows with a column for
the type name (Available, Reserved etc). I populate this as seed data
at application setup.

InventoryAccountTypes don't necessarily need to be in the database
although each account will need to be identified as one or the other
some how (currently via foreign key to the types table). They are also
fairly static and may only change with application feature updates.

I now need to define posting rules which are basically business logic
for whenever a particular entry is made to an account of a certain
type. Each account type has it's own set of posting rules.

I have considered creating an AR model for the posting rules and
associating them with the account type. However I'm not sure about
leverage the database layer to hold so much hardcoded business logic
and relationships?

I also don't like relying on seed data to put business logic
relationships in place.

I feel like I should place the business logic and available account
types firmly in ruby code. What do people think? Has anyone tackled
anything similar?

Thanks, Andrew.

Re: [Rails] Secure receipt generation

[Niels Meersschaert]

Why not just scope the find to the user?

class User
has_many :receipts
end

Then in your controller you can do something like

def show
file_ref = current_user.receipts.find(params[:id])

#Read file code
end

[Rails] Secure receipt generation

[icke]

Has anyone got any ideas on how to approach the following:

I generate a pdf receipt and store it in a directory "outside" of
public since I do not want users to be able to just mess about with
URLs and look at other users receipts.  However, I do want users to be
able to download and see their own receipt.  I am struggling to come
up with a way of the browser showing the pdf but denying access to
other pdf's.

I had thought of using some sort of md5 generated id on a resource
called "receipt" to do a show but in the end there is always some
URL.  Is there a way of creating some sort of "one-time-use" URL by
forming the headers accordingly and then simply using a file-read to
serve up the file.  To me this seems a bit weird as the whole point of
webservers is doing precisely this.

I must be thinking along the wrong lines.

Thanks.

O.

Could you not just test @posts directly, presumably it will be nil or
empty or something, or am I missing something?  I am a bit confused as
I would expect a variable called @posts to be an array of Post objects
but since you are using :id => posts that suggests it is just one.

Oh my mistake ... :)

map.with_options(:namespace => "admin") do |admin|
  admin.clients_index 'clients', :controller => 'clients', :action => 'index'
  admin.clients_edit 'clients/:id/edit', :controller => 'clients',
:action => 'edit'
  admin.clients_insert 'clients/insert', :controller => 'clients',
:action => 'insert',  :conditions => { :method => :post }
end

Hint: Your actions looks to match the resource-pattern

[Rails] Re: Problem installing RoR Ubuntu 9.04

[T_P]

Hi, Luiz!

I had the same problem as you. Namely, I struggled with installing RoR
development environment on my Ubuntu box.
I found a nice and EASY solution: use BitNami RubyStack, which is
available at http://bitnami.org/stack/rubystack. Everything
is included, and it works out of the box. I highly recommend it.

It has a very clear user guide as well, at
http://bitnami.org/files/stacks/rubystack/2.0-0/rubystack.pdf.

HTH.

Assuming that you are on Rails 2.3 or higher, I would use a rack  
middleware for that. You have an example at 
http://www.hokstad.com/rewriting-content-types-with-rack.html

Keep in mind that the Rack config file in Rails is replaced by adding  
the rack middleware to environment.rb instead with:

config.middleware.use NameOfMiddleWareClass

[Rails] Cucumber and general Ruby question

[Gintautas Šimkus]

Hello,

I have this cucumber step definition:

Given /^the site has pages "(.+)" and "(.+)"$/ do | page_1, page_2 |
Page.create :title => page_1 if Page.find_by_title(page_1).nil?
Page.create :title => page_2 if Page.find_by_title(page_2).nil?
end

This works, but obviously I would like to DRY it up. I was thinking along
the lines.

Given /^the site has pages "(.+)" and "(.+)"$/ do | *args |
args.each { |page| Page.create :title => page if
Page.find_by_title(page).nil? }
end

The code is not syntactically correct that is what my question is about: how
to implement this concept right?

Thanks.

[Rails] Ubuntu + RoR + Firebird OR Ubuntu + RoR + PostgreSQL ?

[LuisRuby]

Dear friends,
I am starting to build a system for an university using RoR. I would
like to use Firebird because I worked with it for a long time and I
love it! In this new project I will use a lot of stored procedures,
data referential integrity and so on. But when I looked for the
Firebird adapter for Ruby and the activerecord for Firebird adapter,
it seems to have so few support and so few users, that I am afraid
about its future.
This is one of the most important e-mails I've sent on my life! If
I have to start using Postgre the time is now. But with a great pain
on my heart for the Firebird.
Could someone give me a good advice?
Thank you very much!

[Rails] Re: Problem installing RoR Ubuntu 9.04

[rtacconi]

Usually when you export the path it should work. Check again that the
path corresponds to the gems path where you have the Rails gem. You
can use this command:

gem env

to gather more info about the gem environment and you should be able
to see the GEM_PATH, so check if in that path you have the Rails gem.
It is a boring problem but it is usually a path issue.

Have you installed another version of Ruby? Reply with you gem env
output to get more help.

Tim, the most recent version of hpricot is 0.8.2.  Thus, if you're
reinstalling
things, you might want to begin by making gemcutter.org your primary gem
repository by doing the following:

sudo gem install gemcutter
gem tumble
sudo gem install hpricot

Next, let's poke around your environment a bit by executing the following
commands:

which gem
gem environment
which ruby

Please give that a try and report back.

Good luck,

-Conrad

[Rails] problem starting rails (hobo) app with passenger

[Edward Samokhvalov]

Dear All!

I've set up my apache, passenger and configs, the passenger works, but
the app can't be started. the erros are the following

These are the possible causes:

*
  There may be a syntax error in the application's code. Please
check for such errors and fix them.
*
  A required library may not installed. Please install all
libraries that this application requires.
*
  The application may not be properly configured. Please check
whether all configuration files are written correctly, fix any
incorrect configurations, and restart this application.
*
  A service that the application relies on (such as the database
server or the Ferret search engine server) may not have been started.
Please start that service.

Further information about the error may have been written to the
application's log file. Please check it in order to analyse the
problem.

[Rails] Re: Problem installing RoR Ubuntu 9.04

[LuisRuby]

OK but... I forgot to ask... before any try to solve my problem, I
think I have to uninstall RoR and then reinstall. How to do that? I
found something but as I'm a novice, it's difficult to choose a path.
Thank you for all that gently replied!

Because this is Ruby, not C?

Use = for assignment, not ==

Surely?

[Rails] accepts_nested_attributes_for + paperclip + polymorphic + problem

[Abhishek shukla]

Hello Friends,


I am not able to retrieve the value form page

controller
  offices_controller
def new
 @office = Office.new
end

def create
 @office = Office.new(params[:office])
 @office.save
   end
 end

VIEW
  <% form_for @office do |f| %>
<%= f.text_area :office_name %>
<% f.fields_for :images_attributes do |i| %>
 <%= i.file_field :avatar %>
<%end%>
<%= f.submit "Submit" %>
  <%end%>

Model

Office.rb
accepts_nested_attributes_for :image

Image.rb
 belongs_to :imagable, :polymorphic => true

PROBLEM
 When I press submit, the params[:office] only contain :office_name and
avatar is getting lost? I don;t know where excatly I am getting wrong.

Thanks for any suggestion

Abhis
