[Rails] postgresql broken on windows in 2.3-stable

[snacktime]

The addition of quote_indent in the postgresql adapter has broken postgresql
support on windows.   The postgres-pr gem was the only driver working with
rails on windows, and it doesn't have quote_indent.  The newer drivers such
as ruby-pg  probably do have the quote_indent method, but rails doesn't
support them yet.

I am stopped at how to do migration from rails engine to main
application

in railscasts video they given a rake task like

but this task is not for windows environment.
-
namespace :create_subscription do
  desc "Sync extra files from create_subscription plugin."

[Rails] Days of the Week and Models

[sir ziggles]

Hi All,

Would love to hear your input on this:

I have a model called Demonstration.

A Demonstration can take place on any, some or all of the days in a
given week.

i.e. Monday, Tuesday and Friday

How should I setup my model(s) to support this relationship?  Is there a
preferred method??




Two ideas i've had:
 - Create a model named Days with a row for each day of the week.
Create a days_demonstrations table and create a HABTM relationship

 - Use the built in Date::DAYNAMES that comes with Ruby.  Create a field
in the Demonstration table called 'days' and store the supported days as
a string: 0,3,5.  Then break it up when it's time to use them as check
boxes in the view.


thanks!

[Rails] Re: Daemons causing Mysql::Error:Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

[Ram]

Ummm. Maybe I should cut the long story short.

couple of daemons, when running on server, slow down and crash my
Rails apps. Logs show me errors like

Mysql::Error:Can't connect to local MySQL server through socket '/var/
run/mysqld/mysqld.sock'
&
MySQL server has gone away

Sometimes, I also get a Passenger::Railz::ApplicationSpawner::Error.
Any ideas on what might be going wrong? Tried
"ActiveRecord::Base.connection.reconnect! " in the daemons but that
dint help.

Exactly.  Also, I recommend that you (the OP, that is) take a look at 
Authlogic, which uses a tableless model for user authentication; perhaps 
it will do what you want.

If your model isn't abstracting the DB in anyway, just don't have it

[Rails] table less model

[Craig White]

I want to have a simple model without a table for ACL purposes because
there aren't going to be many methods at all.

How could I have a Model like...

ControllerMethod securitylevel

users_list   8
reports_ar   6
ar_print_checks  7

so I can use retrieve and use these values in a before_filter in
ApplicationController.rb? The intent is to create a lightweight ACL
system.

I don't see the need to actually create a table or store the data in a
table at all.

Any suggestions on how I can accomplish this?

Craig

I think you want two separate models... where one has many of the other.

That is...

class Contact << AR..
   has_many :phone_numbers
end

class PhoneNumber << AR..
   belongs_to :contact
end

Your sql table "phone_numbers" would then have a "contact_id" field.

There's a couple of features beyond 2.3 stable that I'm keen to get my

I need to make a table (class) where one of the columns' (attributes')
type is an array of objects of another class.  In other words, I need to
know how to implement a phone-book list, where you can click on the name
of the entry and be taken to that person's, say, bank info.

Does anybody know of any guides that might walk me through this, or be
able to give me a rough picture of what needs to be done so I can figure
it out myself?

[Rails] UTF-8, AES encryption, the works - help !

[Abe Ced]

Hi,

I would like to store some sensitive data into my DB using Rails, it has
to be encrypted. I've tried a lot of methods of encryption, they all
work. Fine by now, yet when I try to store the results into my DB
(tables are UTF-8, SET NAMES UTF8; is there, server UTF-8, DB Connection
UTF-8) -- I can cmd (yeah, Windows..) and enter a UTF-8 record into the
table, so that's not where the problem is.

So after I use the encryption method (AES, Blowfish yada - all returning
UTF-8, they all work - encrypt then decrypt, strings match), I would
like to store the result in the DB -> Just using an insert with the
encrypted string fails, as it inserts only regular, Latin1-chars, the
other characters are being discarded. I have googled and tried all
options,

ic = Iconv.new('UTF-8//IGNORE', 'UTF-8')
valid_string = ic.iconv(enc + ' ')[0..-2]

raises InvalidCharacter or InvalidSequence on some strings so not
viable.. Should I convert the result of AES and so on into Latin1 ?? I'm
quite lost as you can see, spent too much on it already.

So am I beating around the bush too much (wasted a lot of time on this
already), or should I search for a non-Unicode encryption solution
(Salted base64 ?) ? Message digests like SHA1 MD5 and so on are not an
option, need to be able to recreate the message (username or email, for
instance).

Thanks a whole lot ! I can provide extra details if required, no
problem.

[Rails] Re: Model Name Conflict

[Saty Nos]

Thanks Ar Chon for the prompt response. But that runs me to another 
question.

How is Filter.find() different from ::Filter.find()?
What exactly does prefixing :: does?

I was under the impression that
Filter.find(),
self::Filter.find() and \
::Filter.find()
all the same. What is the difference between them? and how does these 
effect the Dependencies mechanism?

Hope that is not a lot to ask. Thanks in advance.

[Rails] Conditions for Multiple Columns?

[Jay Covington]

Hello,

I have a table called "Itemlist" and have multiple columns in it such as
"item1", "item2", "item3", "item4". These columns often have repetitious
data between them and I'm trying to count it. The only working code I
have so far is:

statcount = Itemlist.count(:all, :condition => {:item1 => "Apple"})

And this works fine for retrieving the count for "Apple" in all the
:item1 fields, but I need to retrieve the count for "Apple" from the
columns :item2, :item3, and :item4 as well as :item1. Any ideas? Thanks!

The association adds some helper attributes to your model.  If you
have an instance of an author you can use the products attribute to
get all of the associated products in an array:

my_author = Author.find(1)
my_author.products

Well, on Rails you can do

date_obj.to_date_time

It's part of ActiveSupport

[Rails] Convert Date to DateTime

[David]

The method I am using to convert Date objects to DateTime objects is:

date_obj = DateTime.parse(Date.to_s)

Is this an okay way to go about doing this?  Or is there a more
efficient way?

[Rails] Does has_many collection '<<' (append operator) always save/create child in DB when parent isn't new?

[Kendall Gifford]

Howdy, the title mostly asks the question.

Given the following:

class Article < ActiveRecord::Base ; has_many :comments ; end
class Comment < ActiveRecord::Base ; belongs_to :article ; end

I have an article already instantiated in the database, referenced as
@article.

Will the following code always "create" (save to DB) a new comment?

@article.comments << Comment.new :text => "Blah blah..."

I would like to be able to add comments to an article that already
already exists (and may already have comments that exist) in the
database w/out the new comment being saved to the database.

I would try this: @article.comments.build :text => "Blan blah..."

The reason I don't is because my Comment class is sub-classed using
STI. Thus, my code really looks more like this:

klass = Comment.get_class(params[:comment_type]) # get_class returns
Comment or a sub-type
@article.comments << klass.new :text => "Blah blah..."

Anyone have any ideas on how I can add STI comments to an article w/
out saving them, doing so "the right way" (I'm sure I could ugly-hack
it)?

Thanks.

[Rails] Re: multiple controllers/views for one model

[Robert Walker]

JannaB wrote:
> How does you handle this in the Rails MVC design? I already have a

The first thing I would suggest is to take a step back from Rails and 
try to focus on Model-View-Controller itself. What you are describing is 
one of the fundamental design principals that MCV was created to solve.

The model should exist entirely independently from any views or 
controllers. This is often referred to as decoupling. Any system based 
on MVC should be able to share the same model with any number of views 
and controllers.

Views and controllers are typically more tied together than are models 
to view and controllers. What you want to separate from views and 
controllers are the responsibilities. Plus there is usually not a 
one-to-one correspondence between views and controllers. Imagine a 
Graphical User Interface that contains buttons, text boxes, combo boxes, 
checkboxes, image views, etc. Each of these are typically instances of 
view classes. There is a "button" class, a "text box" class, etc.

These view are then composed into a hierarchy, and the hierarchy is 
typically managed by a single controller. The responsibility of the 
controller is to react to, and process, user input (e.g. clicking a 
button or entering text in a text box). Then the controller takes that 
input and communicates with the model (if necessary) and uses the data 
to update the views, hence providing feedback to the user.

Now back in the world of Rails, much of this still holds true. Views 
provide the interface to the user in the form of web forms with text 
boxes, submit buttons, etc. The difference is rather than an event loop 
that processes user interaction in "real time," web applications 
typically have a request-response cycle and process user input in 
"batches." The controller would typically receive all the user input 
from a web form in one chunk (the URI and parameters). Then interact 
with the model and produce a "page" as output to present back to the 
user.

An additional aspect to Rails MVC is that controllers, along with the 
routes file, serve to map URIs to resources. Keep in mind that resources 
are not equivalent to controller+model.

While it makes sense to have one controller and a set of views to manage 
a "User" resource. You are not at all limited to one controller per 
model. Maybe in your case you might have a "Friend" resource that has 
it's own controller and set of views that shows information about a 
user's friend. The friends_controller might then have a "show" action 
that displays information about the friend's whereabouts. I don't know 
if all that makes sense, but it should serve to illustrate the idea of 
resources as something separate, and in some ways more abstract, than 
controllers and models.

All controller parameters are strings, so this negation doesn't do
what you think it does (because strings are not nil and they are not
the boolean value false, any string always has the logical value true,
and its negation the logical value false). You need to compare the
parameters with whatever string you have decided represents true/false

[Rails] Simple problem of negating boolean in params-hash

[Adrian D]

Hi,

I have a simple problem. I get a boolean value in the parameter hash
and want to negate it. But somehow I missed there a fundamental
concept, because that doesn't make any sense to me:

Code:

test1 = !params[:editmode]
test2 = params[:editmode]

logger.info("Editmode: #{params[:editmode]} Test 1: #{test1} und Test
2: #{test2}")

Output:

"Editmode: false Test 1: false und Test 2: false"

or when editmode is true: "Editmode: true Test 1: false und Test 2:
true"

Thanks for your help

[Rails] Re: instance variable (conroller>view) and RESTful

[zambezi]

Hi to Colin, Jennifer and anyone else,

If nothing else, this forum serves as a sanity check.

My difficulty arose when I created an application wide template as a
container for various views and attempted to pass a title variable to
the template.  None of my fiddling raised any errors.  After reading
your replies I went back to my application and sacrificed another hour
to Ruby idiosyncracies.  Here is what I've done and the results.

# within layout/application
class LinkController < ApplicationController
def display
@title = "title (display)"
end
def index
  @title = "title (index)"
end
def foo
  @title = "title (foo)"
end
end

<%= @title %>
---
I created a view named 'display'  with the above embedded Ruby and
opened it in the browser.  The title was BLANK.
Next I renamed the view 'index' and opened it in the browser. The
title appropriately showed "title (index)"
Then I renamed the view 'foo' and again a BLANK title.
I renamed the view back to 'index' and the title reappeared.

The above was with a template, so I decided to try the same fun
experiment with a standalone view.  And things got murkier.  Views
named 'index' and 'foo' display their titles.  Views named 'display'
are BLANK.

Just on the off chance that Ruby is weirder than I think, I checked
the list of reserved words.  No conflicts there.  I also considered
there might be something bizarre about the title tags, so just stuck a
variable in the middle of the view  <@= @title %>.  This
just reproduced the earlier results.

So there is the sad story.  Help!  I suppose I can just test all of my
view names to see if they pass muster, but I am really hoping to
eventually get to where Ruby is a time saver.

Any suggestions and/or comments on the instance variable behavior will
be welcomed.

Bill

[Rails] Forcing use of gem in vendor/gems?

[Denis Haskin]

Sorta surprised this isn't a FAQ, but...

Maybe this is not good practice, but I have a gem that is both installed 
in the system and in vendor/gems.  The vendor/gems copy has some local 
mods.  Seems like the only way I could find to forced that one to be 
loaded for capistrano over the system one was to put:

$LOAD_PATH.insert 0, 
"#{File.dirname(__FILE__)}/../vendor/gems/myfavoritegem/lib"

in deploy.rb.

Is that really the best way to do it?  I guess I was sort of figuring 
that vendor/gems would be preferred over the system gem library, in the 
case of duplicates.

Thanks,

dwh

[Rails] Outlook like calendar

[CiriusMex]

Hi,

I'm working on a reservation system for a site and I would like to
display a calendar with the programation of a cine movies or the hours
of classes for a gym center...that kind of stuff.
The Outlook calendar is really great, and on the other hand I want the
calendar to be displayed for the selected day, week or month just like
in outlook...

So if anyone know of a existing component that already does this it
would be great and save me a couple of hours of development :)

Thanks for the help and have a good day ^^

[Rails] Access values with has_and_belongs_to_many assocciation

[LOUPOS KONSTANTINOS]

Hi!
I have 2 models author and product.

class Author < ActiveRecord::Base
  has_and_belongs_to_many :products
end

class Product < ActiveRecord::Base
  has_and_belongs_to_many :authors
end

I have also created the migration for the jointable authors_products
with the keys author_id and product_id.

Now, i suppose that when i have eg an author with author_id = 1 and a
product_id=4 in the join table, i should be able to access the product
title of that product and the author name of my author.

How can i access these values???

Thanx in advance for your time!

[Rails] smart data loading

[Greg Donald]

I need something to load my seed data when I stage my app for
milestone releases.  I'm using fixtures currently but maintaining the
foreign key relationships is getting more difficult as the app grows

I'd like something that's aware of my foreign keys constraints and
knows to load the data in the proper order.

I've looked at FactoryGirl and seed_fu so far but would love to hear
of any alternatives.

[Rails] Model Name Conflict

[Saty Nos]

I have a model by the name Filter but due to the changes in reorganizing
the filters from 2.0.3, it is conflicting with the

ActionController::Filters::Filter (class)

In my filters_controller.rb when I try to find the filter

Filter.find(:id)

as rails is infering the ActionController::Filters::Filter class rather
than my model class Filter. Is there any work around other than renaming
my model?

BTW: If I use ActiveRecord::Base::Filter.find(:id) to load my filter
object, its working, but I am not quite sure if there are any unforseen
implications by doing this, when rails try to unload/reload constants.

Thanks in advance.

Is the title declared unique?  Then Rails queries the DB to check that there

[Rails] Updated Tutorials?

[J. D.]

Summary:

Every book I've purchased has either been a) outdated using rails 1.x or
b) outdated using rails 2.x where there are issues working through some
of the books.

A good example is a book that others said was wonderful.  It's called
Foundation Rails 2.

I started going through the book and everything is being taught the
exact way I like to learn.  So, I'm thinking "alright this is great!".
Then, I get to the first partial tutorial involving "clients".  I'm
supposed to add the unfinished clients (that I downloaded) and work from
that.

I download it, place it in my projects directory, fire up netbeans 6.5
and add it and encounter a rake error.  I try to get more information so
I drop down into a command prompt and run rake -D on the directory
called Clients and receive the following error:

rake aborted!
undefined method 'new!' for Rational:Class
C:/Ruby/lib/ruby/gems/1.9.1/gems/rake-0.8.7/lib/rake.rb:2383:in
'raw_load_rakefile'

I spent hours finally getting both mysql and sqlite3 up and running on
1.9.1 on a windows environment and I'm able to create new projects in
either DB platform on rails using netbeans 6.5.

However, it seems that every tutorial I find (other than the 10-minute
weblog tutorial for netbeans) has failed or is outdated and contains
errors.  I wouldn't be bothered by this so much if it wasn't for the
fact that I've paid money for these books and many of them have some
nice concepts but nothing to work with or through.

So, my frustration is not with rails and it's ever changing environment.
It's that people are selling books that are stating they work fine with
rails 2.x and they aren't.

Are there any tutorials out there that work for rails 2.3.2 that I can
follow along with and where?  I'd love to learn more about the model
transitioning with databases..  I've learned a great deal already but
I'm missing tutorials that interact with databases.

Many thanks in advance.

[Rails] rendering layouts/views from plugins

[wbsurf...@yahoo.com]

 I am wondering if there is an easy way to render layouts and views
from the plugin directory, as well as javascript and css ?

 I know I could have a rake task copy them from the plugins to where
they would normally go, but they may change from time to time within
the application and then need to go back into the plugin. If I cause
them to function as a plugin, then as I develop my app, the plugin
changes as well. This is just a plugin that I use for myself only and
would not get used alot except shared between a few apps, though if I
updated it, I would update it in one app and then copy the changes to
the other apps by copying that plugin from one app to another.

 The other possibility is I could have a rake task copy them from the
app back into the plugin dir, but that seems sort of strange.

 I'm not sure if there are some better approaches ...

That looks like it was trying to find a class called FreakProject and
you only have Freak_Project. Use the :class_name option to belongs_to/
has_many.

[Rails] Re: process request and redirect to another url with all params

[Mk 27]

The key issue here is that this will need to be send as a POST request, 
whereas I assume the default of redirect_to is GET.

You will have to put the params onto to the end of the url string 
yourself, eg.

param1=this¶m2=16¶m3=that

[Rails] why the cult-like adherence to the One True Way of Agile works...

[Phlip]

 From else-net, here's the results of an informal survey why professional 
testers who actually help do all the developer- and customer-testing we authors 
advocate feel about the results:

Here's my final top ten list, with responses from this list, twitter, and 
coworkers. Thanks for all your contributions!

Top Ten Reasons I Love Agile Testing:

10. No more manual test scripts!

9. I don't have to work in a cubicle.

8. I'm allowed to think about stuff and learn stuff.

7. Developers don't hide when they see me coming!

6. I investigate and solve complicated, interesting problems every day - and 
they pay me to do this!

5. I can impact quality, instead of just documenting it.

4. Customers actually like the product.

3. No more death marches!

2. There's always time for testing, because testing happens first.

And the number one reason I love agile testing...

1. I get to hear people say "this is the best project I've ever worked on in my 
life!"

[Rails] override finders?

[Michal Burak]

Hi,

1.
I have my model for e.g. "Car".
I used this model in lots of places.

2.
In a migration I added Car.is_visible default => false.

3.
Now I wan all of the finder methods to take this flag under
consideration. So initaly none of the Cars will be displayed on my site.
I will have to look for the places where I want to display "not visible"
cars and there add the special condition to the finder method (whitelist
pattern).

Any help appreciated.

[Rails] process request and redirect to another url with all params

[Doug Mathews]

I am trying to do the following:
process a request containing form data. Once I my app has successfully
completed its processing, I would like to redirect_to a totally
different site and pass along the parameters that came in with the
original request.

This is how I am currently handling it in the controller:
[code=]def create
  @subscription = Subscription.new(params[:subscription])

  @subscription.user_id = current_user.id

  @subscription.subscribe

  respond_to do |format|

  if @subscription.save
parms2 = params

format.html {redirect_to
"http://www.someothersite.com/process",parms2}
  else
   #handle the problem
  end
end

  end[/code]
Everything up to the redirect is happening correctly. Then I am
redirected to www.someothersite.com but it is behaving as though the
parms2 are missing. I am new to Ruby and Rails and am probably missing
something very easy here.

Thanks in advance.

[Rails] multiple controllers/views for one model

[JannaB]

I am wondering how to handle this: I have a model, 'users'. The table
can be edited. So far, so good, standard CRUD on a given model,
standard views, etc.

One of the fields in the users table is a text field for their
whereabouts, with info put in by the users themselves. I want a
different, separate view in my application, that shows only ther
whereabouts of a select user. So, in this second view, a user picks a
different user to see where he or she is.

How does you handle this in the Rails MVC design? I already have a
controller and a view for users (where you CRUD on the user). How do
you handle different required functionality/view like this? Thanks,
Janna

[Rails] IE6 CSS and Rails Routes

[bhan...@hcinsight.com]

I dont know if anyone has come across this issue.

I have 2 different layouts for my app. both contain the same partial
with the same CSS files in the head.

in that i also have a IE6 CSS Hack file. Pretty standard.

The Problem in IE6
My issue is this. on any of my main pages that have named routes like
so
  map.privacy 'privacy-policy', :controller => "information", :action
=> "privacy_policy"
  map.admin 'dashboard', :controller => "admin", :action =>
"dashboard"
  map.home 'home', :controller => "information", :action => "home"
  map.search 'search', :controller => "information", :action =>
"search"

the CSS is picked up fine. but if i go to an action like /information/
home (this is in the url vs just home), where the controller is
listed. The CSS breaks and doesnt render the page correctly. But...
The file is still listed in the source(view source)..

very strange. any help would be great.

Thanks

[Rails] [ANN] ri_cal 0.5.3 Released

[Rick DeNatale]

ri_cal version 0.5.3 has been released!

* 
* 

A new Ruby implementation of RFC2445 iCalendar.

The existing Ruby iCalendar libraries (e.g. icalendar, vpim) provide
for parsing and generating icalendar files,
but do not support important things like enumerating occurrences of
repeating events.

This is a clean-slate implementation of RFC2445.

A Google group for discussion of this library has been set up
http://groups.google.com/group/rical_gem

Changes:

### 0.5.3 - 1 June, 2009
 * Improved performance of time zone enumeration, TimeZonePeriod now
caches occurrences
 * Added a profiling directory which contains ruby programs which
benchmark and/or profile performance
### 0.5.2
 * Fixed http://rick_denatale.lighthouseapp.com/projects/30941/tickets/11
   Export folding is not UTF-8 Safe

### 0.0.4
 * Fixed a bug in imported timezones reported by paulsm on github
### 0.0.3
 * Added tzid method to Ruby Time and DateTime instances, and to
ActiveRecord::TimeWithZone if it is defined this method is used to
determine the desired
timezone when an instance of one of these classes is given as the
value of a datetime property.  If the tzid is nil then the default
tzid is used,
if it is set to :floating then the property will be a floating time.
 * Removed the ability to pass an array with a tzid string and a
date-time since the above made it unnecessary
 * The ruby datetime property returned from the ruby_value method on
the DateTime property will return an instance of ::DateTime with:
   ** The proper utc offset
   ** The tzid set to the right tzid
 * Made exdate/rdate building possible
 * Added a default_tzid attribute to the Calendar component, if this
attribute is not set for a particular calendar it will delegate to the
default set
for the DateTime property class.
 * Added fix patches from
   ** http://github.com/kjwierenga/ri_cal
   ** http://github.com/wesmaldonado/ri_cal

### 0.0.2
 * Fixed gemspec
## 0.0.1

[Rails] Specific exceptions for database errors: please speak up

[Michael Schuerig]

With ActiveRecord as it currently is, you get the same error for 
anything that might go wrong in the database, 
ActiveRecord::InvalidStatement. That's rather undistinctive, considering 
that there are some problems only the database server can recognize, in 
particular violated uniqueness and foreign key constraints.

If specific exceptions for these tow latter error conditions would help 
you in your code, or if you are interested in the topic in general, 
please review the following ticket and patch

https://rails.lighthouseapp.com/projects/8994/tickets/2419-raise-
specific-exceptions-for-violated-database-constraints

Please state your opinion and/or support, for otherwise the issue might 
be delayed interminably.

Thanks,
Michael

[Rails] Engine Yard Adds JRuby Support -- http://bit.ly/MALvT

[LJMecca]

Today at Java One, Engine Yard is announcing support for JRuby. This
means that people will soon be able to select JRuby as a runtime
option in the Engine Yard Cloud, and subsequently on the Engine Yard
private cloud for cluster and slice customers. Engine Yard is excited
to partner with Charlie Nutter and Tom Enebo and the broader JRuby
team to make this happen.

[Rails] Re: Ruby and RoR Setup Frustrations

It's not an IDE, but I really like the 'e' text editor for ruby/rails

textmate clone (or started out that way anyway).

Jruby is not for me - it looks more like a pre-packaged version that is not

work with 1.9.1.

[Rails] Re: ruby 1.9.1, cygwin & rails 2.3.2: undefined method camelize

[danmack-gmail]

Thanks for the tip.  I already have that package installed so the
problem might be that my private (/opt/ruby.../)  copy of ruby didn't
see or detect the iconv stuff when I built it from the source code.

I don't see the ruby-iconv package on cygwin so there must be another
package or build option I'm missing there.

[Rails] Re: nested forms with select lists

[anrake]

Thanks. Somewhat edited, it basically looks like this.

MODEL:

class Cpicture < ActiveRecord::Base
  belongs_to :historicsite
  has_many :tags, :dependent => :destroy
  accepts_nested_attributes_for :tags, :allow_destroy => true,
  :reject_if => proc { |attrs| attrs.all? { |k, v|
v.blank? }}
end


VIEW: part of edit.html.erb
<% cpform.fields_for :tags do |tag_form| %>
<%= tag_form.select('tag', 'tag_group', [["value_1","value1"],
["value_2","value2"], ["value_3","value3"]]) %>
<%= tag_form.select('tag', 'tag_name', [["value_1","value1"],
["value_2","value2"], ["value_3","value3"]]) %>

<% unless tag_form.object.nil? || tag_form.object.new_record? %>
  <%= tag_form.label '_delete', 'Remove:' %>
  <%= tag_form.check_box '_delete' %>
<% end %>
<% end %>

CONTROLLER:

  def edit
@cpicture = Cpicture.find(params[:id])
2.times {...@cpicture.tags.build}
  end

  def update
@cpicture = Cpicture.find(params[:id])
if @cpicture.update_attributes(params[:cpicture])
  flash[:notice] = 'Cpicture was successfully updated.'
  redirect_to :action => 'show', :id => @cpicture
else
  render :action => 'edit'
end
  end

[Rails] Re: how to use fusion charts in ror

[diegocal...@gmail.com]

Are you still having problems?

There are many ways to display the chart but the one I've used and
works fine for me is to create dinamically the XML using a builder and
then to render it in the view. You just need to include the js file
under /public/javascript/ and to include the SWF file under public/

[Rails] Re: Calendar in Rails

[Joao Silva]

Check out http://github.com/p8/table_builder/tree/master. It works 
similar to form_for. It requires objects with a method that returns a 
date.

  <% calendar_for(@tasks, :year => @year, :month => @month) do |t| %>
<%= t.head('mon', 'tue', 'wed', 'thu', 'fri', 'sat', 'sun') %>
<% t.day(:day_method => YOUR_DATE_METHOD) do |day, tasks| %>
  <%= day.day %>
  <% tasks.each do |task| %>
  <%= h(task.name) %>
<% end %>
  <% end %>
<% end %>
  <% end %>

[Rails] radio_button_tag checked='checked'

[Chetan Thorat]

Hello,


I have 3 radio buttons,

<%= radio_button_tag('method', 'auto', checked = 'checked',
options = {:onclick => "Element.show('avsAutoWrapper');
Element.hide('avsCustomWrapper'); Element.hide('avsLocalWrapper');"})
%>Auto

<%= radio_button_tag('method', 'custom', checked = false,
options = {:onclick => "Element.hide('avsAutoWrapper');
Element.show('avsCustomWrapper'); Element.hide('avsLocalWrapper');"})
%>Custom

<%= radio_button_tag('method', 'local', checked = false,
options = {:onclick => "Element.hide('avsAutoWrapper');
Element.hide('avsCustomWrapper'); Element.show('avsLocalWrapper');"})
%>Local

Every radio button has its respective text field.
I want radio button Auto to be checked default.

And these are their 's


<%= render(:partial => "a_b_auto", :object => @product_build) %>



<%= render(:partial => "a_b_custom", :object => @Product_build) %>



<%= render(:partial => "a_b_local", :object => @product_build) %>




Now when the application starts and the page containing this three radio
buttons display at the very first time,I can see all the three text
fields of all of these radio buttons,which I don't want.

Just the text field of respective radio button must be displayed.
But this is not happening..
I had also tried the following format of radio buttons

<%= radio_button_tag('method', 'local', checked = true,
options = {:onclick => "Element.hide('avsAutoWrapper');
Element.show('avsCustomWrapper'); Element.hide('avsLocalWrapper');"})
%>Custom


and

<%= radio_button_tag('method', 'local', true,
options = {:onclick => "Element.hide('avsAutoWrapper');
Element.show('avsCustomWrapper'); Element.hide('avsLocalWrapper');"})
%>Custom

but it wont work.


Please help me.

Thanks

Chetan.

[Rails] Re: using attachment fu in masse

[holden]

nevermind found this lurking in the documentation... i suppose i
should have read it better before looking else where... ;-(

#!/usr/bin/env ./script/runner

# required to use ActionController::TestUploadedFile
require 'action_controller'
require 'action_controller/test_process.rb'

path = "./public/images/x.jpg"

# mimetype is a string like "image/jpeg". One way to get the mimetype
for a given file on a UNIX system
# mimetype = `file -ib #{path}`.gsub(/\n/,"")

mimetype = "image/jpeg"

# This will "upload" the file at path and create the new model.
@attachable = AttachmentMetadataModel.new(:uploaded_data =>
ActionController::TestUploadedFile.new(path, mimetype))
@attachable.save

[Rails] Re: Routing Error with Passenger for Images and stylesheets

With thanks to Hongli Lai over on the Phusion Passenger Google Group, I 
got this sorted out. And for completeness and to help others this is 
what I did.

I set up a new directory under /var/www:

/var/www/myapp

and created a symlink from there to my app's public folder:

ln -s /home/me/public_html/myapp/current/public myapp

and changed my apache vhost file to be:


  ServerName myserver.com
  DocumentRoot /var/www/myapp
  
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
  
  RailsBaseURI /myapp


and made sure to include:

config.action_controller.relative_url_root = '/myapp'

in my environment.rb file.

Hongli's description:

> /var/www/myapp should be a directory. Inside this
> directory there should be a 'myapp' symlink. Like this:

Hope this helps someone else!

[Rails] ArgumentError - Unable to rectify please help

[Aslam Syed]

Hello,

I am stuck in a problem which I am unable to understand. I am trying to
send an email, which I have done before, after user registers himself on
a website. User provides email address which he has to confirm before
getting any further communication. I have to do three things before the
user object is saved, like creating some other records and sending email
to confirm email, in a transaction. But, rails is throwing some error
(ArgumentError (interning empty string)) while calling
Mailer.deliver_confirm(email, code).

The stack trace is at http://pastie.org/496446

Please provide suggestions as where I am going wrong. I am using
Rails-2.3.2 and Ruby-1.8.7 this time.

[Rails] Quick question - access attributes through form helper?

[Mark Dixon]

So within a form_for/fields_for can I access the field attributes.
[code=ruby]<%= form.text_field :name %>#gives me a text box with the
value of :name %>
<%= form.label :name %>#gives me a label with 'name' when I need the
value of :name %>
  # Can I also do something
<%= form.text_field :category %>#gives me a text box with true or false
%>
 <% if :category %> # access an attribute in this way in order to affect
condition??[/code]

[Rails] Re: Model structure based on unavailable data

[Matt Jones]

This is the more typical Rails idiom - it's how ActiveRecord generates
all kinds of things, from dynamic finders (find_all_by_foo) to
attribute methods.

Can you verify if following things are in proper place.

1. Are you able to connect to mysql otherwise on your system.
2. Have you done $gem install mysql
3. Copy libmySQL.dll from MYSQL_INSTALL/bin  forlder to RUBY_INSTALL/
bin folder
3. Verify database.yml has your password

Yea, for some reason I erroneously added "@" to @listhub and was too 
tired to see it. The removal of this worked fine. Thanks!

This is basically rails not knowing about inverse associations (which
it will do in the next version).
If you do do itself you should use increment_counter rather that doing
what you show above (which has a race condition).

[Rails] Re: counter_cache is making a redundant SELECT before UPDATE

[Fernando Perez]

Hmm, actually I just watched the railscasts about the counter_cache, and 
in his log he also has this redundant SELECT that he didn't even spot.

So I guess this could be an additional feature added to Rails to save 1 
DB query.

[Rails] counter_cache is making a redundant SELECT before UPDATE

[Fernando Perez]

Hi,

I have the following code:

Message, belongs_to :topic, :counter_cache => true

topic = Topic.find_from_permalink(params[:id])

topic.messages.create(params[:message])

When the message gets created, then AR issues a supplemental SELECT to
retrieve the message's topic and then updates its messages_count. Why is
that happening?

If I do it manually:

if topic.messages.create(params[:message])
  topic.messages_count += 1
  topic.save!
end

Then I don't get this additional SELECT. Does the sql cache only work
when I do Topic.find(2) ?

[Rails] Re: using attachment fu in masse

[holden]

I tried using ActionController::UploadedStringIO.new( data )

and it does create the files... but the images don't work.

Is data supposed to be the filepath?  ie. photos/joe.jpg ?

I also found an example of exactly what I want to do in the Practical
Rails Plugins book, but which is outdated using "temp_data ="  It
looks simple and perfect, what am I missing?

[Rails] Form validation on non-CRUD activities

[Tom R]

Hi there,

I'm relativity new to Rails (I've been eying it for some time,
though). I'm reasonably familiar with Ruby's syntax.

When I pick up a new language, I like to make a simple blog. I'm
focusing on the authentication at the moment. I am well aware of the
existing plugins out there, but since this application will never see
the light of day and I learning by rolling my own.

Now, let's say I have a login form, how do I validate that? I'm not
saving into  a model, or anything like that. At this stage, I'm just
using a form_tag, and doing simple if params[:username] == '' in the
controller. Very ugly indeed.

What is the best way to validate a form (and get the nice error
messages, like when you are scaffolding) when you are not necessarily
saving data?

Cheers.
Tom.

if you're guarenteed that the format you get in the controller is
going to be dd.mm. then strptime is probably the easiest way
(although just tearing the string up with a regexp wouldn't be hard
either)

[Rails] Nested models and forms

[Sahil Dave]

Hi,

I have been trying to use the new nested models & forms feature in rails 2.3

#helper

def add_job_profile_link(name, form, vacancy)
link_to_function name do |page|
  profile = render(:partial => 'job_profile', :locals => { :f =>
form, :job_profile => vacancy.job_profiles.build })
  page << %{
$('job_profiles').insert({ bottom: "#{ escape_javascript profile }"});
  }
end
end

#view


   <%= render(:partial => 'job_profile', :locals => { :f => f,
:job_profile => @vacancy.job_profiles.build }) %>


   <%= add_job_profile_link("Add a job profile", f, @vacancy) %>


The above code is displaying the fields, but on submission picks up values
for just 2 nested models. I tried removing the default rendered partial, and
then it picks up just 1 set of values.
Am i doing something wrong over here?
Does @vacancy.job_profiles.build has different meanings in view and helper?


Regards

Well yes, I already do so (calendar_select_date), but I get in the 
controller-function as params the dd.mm. format. So 
update_attributes convert the date automaticly, but it do it wrong 
(mm.dd.), therefor I "repair" the Date.parse-Function.
