[Rails] Re: Versionning system

[Bosko Ivanisevic]

I rarely use GUI tools that come with git. Although gitk is really
excellent if you want to examine history, especially since feature to
use external diff viewer is added. MinGW version of Git works good on
Windows but if you need to use git-svn you'll have to work with Cygwin
because MinGW version still doesn't work well.

Nevertheless what really amazed me in Git are easy branching and
merging, git stash (put away your current, not commited work, make
changes and applying ongoing work back) and git bisect that is really
helpful in chasing bugs that occur at some point in time.

[Ferdie Ferdie]

Hi,

Anyone can helps to display a summary list instead of a details list.

Here is my code;

recgroup = eval(tablename.fieldname) if !tablename.fieldname.nil?

puts  recgroup[:textgroup] + recgroup[:countgroup].inject(0) {|sum,
room| sum + room.length}.to_s + '; ' + recgroup[:countgroup].length.to_s
if !recgroup.nil?


It was displays as a details;

textdata1 1 1
textdata2 1 2
textdata1 2 2


But I need to display as a summary;


textdata1 3 3
textdata2 1 2

 2) File uploaded sucessfully, conversion of movie file to flash file in
progress

So along with a progress bar it should display the above texts, in each
process. Please suggest me a way to do?

  Category.find( :all ).collect {|c| [ c.category_name, c.id ] }
%>

<%= submit_tag "uploadfile", :url => {:action => 'add'}, :class =>
'submit' %>

<%end %>


My controller(videos_controller)

else
   video_name=params[:image][:blob].original_filename
   video_size = params[:image][:blob].size/1024
   @video.video_size = video_size
   videoname = video_name.split('.')[0]
   videoname_type = video_name.split('.')[1]
   if videoname_type == 'flv' or videoname_type == 'swf'
  @video.video = video_name
  if @video.save
 File.open(RAILS_ROOT + "/public/videos/" + video_name ,
"wb") do |f|
 f.write(video.read)
 system "ffmpeg  -itsoffset -4  -i

[Rails] Is there any way to let the user edit the stylesheet file?

[Bob Sanders]

I'm curious how to let the user edit the public/stylesheets/site.css
file through views (e.g., http://localhost/admin/edit_stylesheet).

Do you know what steps I should take, or is there any documentation on
how to do this, or any resources I should look at?

[Rails] Re: routes.rb question

[Joshua Abbott]

Richard,

Why not just lose this line from your routes file:

map.connect '/:controller/:action'

Since map.resources came along, I always delete the default stuff that 
comes in the routes file. See if /phrases/new works the way it should 
after removing that line.

[Rails] ActiveRecord handling of obj.dup vs obj.clone

[Daudi Mogaka]

AR seems to be handling model object dup and cloning differently from
Ruby documented behavior.  I've checked out both ways (as an AR model
and not) and the behavior is different.  I don't see anything in the
RAILS documentation about this.  Am I missing something? is this a bug?
a feature? an interesting lifestyle?
I can easily hack around this difference/bug/feature but it should be
unnecessary.
---
example 1 using AR:

class Model < ActiveRecord::Base
# etc, normal model stuff, associations
  def initialize_copy(old_obj)
# do something
  end
end

obj = Model.find(1)
obj_dup = obj.dup   # does NOT yield a new object;
# does invoke obj_dup.initialize_copy(obj)
# at this point obj_dup is same object as obj;
# any changes to obj_dup will change obj
# but obj_dup changes have not been saved to DB yet

obj_clone = obj.clone  # does yield a new object;
   # does NOT invoke obj_clone.initialize_copy(obj)
# at this point obj_clone is a different object but not yet saved to DB
# which is ok and expected; NOT invoking initialize_copy is NOT ok

example 2 using pure Ruby:

class Test
   attr_reader  :name
   def initialize(str)
 @name = str
   end
   def initialize_copy(old)
  @name += ' *** COPY ***'
   end
end

a = Test.new 'john'   # a.name is now: 'john'
b = a.dup# b.name is now: 'john *** COPY ***'
c = a.clone  # c.name is now: 'john *** COPY ***'

# a, b, c are all DIFFERENT objects
# b.initialize_copy(a) was invoked per Ruby documentation #
c.initialize_copy(a) was invoked per Ruby documentation

[Rails] Re: Validating a legal subdomain

[Jeff]

I eventually settled on a regex that permits only letters, numbers and
hyphens. Close enough for my needs:

  validates_format_of :subdomain,
  :with => /^[a-zA-Z0-9\-]*?$/,
  :message => 'accepts only letters, numbers
and hyphens'

Hope that's helpful!

It isn't wrong, it's the right way to do it. You just have to
assign a category object when building a new Product.

In this case you may need validates_associated or write your own
validation by def validate.

[Rails] Re: Issue with scaffolding with rail 2.2 and mySQL

I think that's crap. The scaffold should create the table if it does
not exist but if the table already exists then inspect the table and
generate the appropriate stuff. What a pain in the ass.

[Rails] Re: Validating a legal subdomain

[scottmotte]

I think what Jeff meant is how to validate the subdomain as a normal
combination of letters and integers without a bunch of strange keys.
He's not talking about authentication, he's talking about validation.

I'll post here if I get this going Jeff. I'm also working on a way. It
looks like it will have to be a regular expression.

[Rails] routes.rb question

[Richard Schneeman]

I'm trying to go to localhost/phrases/new

where 'phrases' is my controller and 'new' is my action which will
simply show my new.html.erb

In my routes i have:
  map.connect '/:controller/:action'

Yet every time i go to phrases/new, I get redirected to my show action

http://pastie.org/356249

I can get around this if i use:
  map.connect '/:controller/:action.'

But i find it distasteful to have that period at the end of my URL. Any
clue why everything gets redirected to :action => 'show'

[Rails] Binary Data over JSON/XML?

[Jörg Battermann]

Hello there,

I am currently putting together a rails-based web application which
will only serve and receive data via json and xml. However, some
requirements contain the ability to upload binary data (images). Now
to my understanding JSON is not entirely meant for that... but how do
you in general tackle the problem of receiving binary files/data over
those two entrypoints to your application?


Cheers and thanks,

[Rails] What is wrong with validates_presence_of :my_association ?

[Ben Johnson]

Category.has_many :products

Let's say a product must belong to a category. I know it is recommended
to do the following:

class Product
validates_presence_of :category_id
end

But, as we all know, this is a pain for new records, meaning what if the
associated category is a new record?

I've been meaning to ask this, but what's wrong with doing the
following:

class Product
validates_presence_of :category
end

I never understood why that was so wrong. So I wanted to ask and see if
I am missing something. What do you think? Thanks for your help!

[Rails] Re: NEWBIE: How come I don't see new database records?

[Tom Nen]

Ben, Thanks for the reply. Do you know how I can toggle to "production 
mode"? I see 3 databases in the database.yml file (development, test, 
production).

Thanks for your help.

[Rails] Re: NEWBIE: How come I don't see new database records?

[Ben]

Look in your config/database.yml file to see how your databases are
configured.

You should be in production mode on your server.  I'm guessing you are
looking at the wrong db.

[Rails] NEWBIE: How come I don't see new database records?

[Tom Nen]

I just inherited a Ruby on Rails web site. I don't know anything about
this topic (I do VB.NET normally). I'm so confused that I'm about to
either throw my laptop out the window or throw myself out the window

I connected to MySQL Query Browser and added a record using an INSERT
command. But then on the web site, I don't see the new record anywhere.

And vice versa... I add a record into the web site's CMS program but
then I don't see it anywhere in MySQL.

I don't know anything about Ruby on Rails apps. Do I need to compile it
before seeing changes? or run some sort of deployment utility?

Any help would be very helpful...

My last post was wrong. The only place we need to define the
relationships is in the join model, the other models can be blank. It
is even cleaner now!!!
One problem I still have is the "destins" (addresses ,phones ,emails,
etc.) can belong to many "origins". I need to make this work as a
has_one instead of a has_many.

git submodule add git://github.com/fauna/has_many_polymorphs.git
vendor/plugins/has_many_polymorphs
git submodule init
git submodule update

ruby script/generate model User name:string
ruby script/generate model Business name:string
ruby script/generate model Charity name:string

ruby script/generate model Address street:string street2:string
city:string state:string zip:string
ruby script/generate model EmailAddress address:string
ruby script/generate model Website address:string
ruby script/generate model PhoneNumber number:string

ruby script/generate model Linkage

class CreateLinkages < ActiveRecord::Migration
  def self.up
create_table :linkages do |t|
  t.references :origin, :polymorphic => true
  t.references :destin, :polymorphic => true
  t.timestamps
end
  end
  def self.down
drop_table :linkages
  end
end

Origins
--
class User < ActiveRecord::Base
end
class Business < ActiveRecord::Base
end
class Charity < ActiveRecord::Base
end

Double Polymorphic Join Model
--
class Linkage < ActiveRecord::Base
  # id:int
  # origin_id:int
  # origin_type:string
  # destin_id:int
  # destin_type:string

  belongs_to :origin, :polymorphic => true
  belongs_to :destin, :polymorphic => true

  acts_as_double_polymorphic_join(
:origins => [:users, :businesses, :charities],
:destins =>
[:addresses, :email_addresses, :phone_numbers, :websites]
  )
end

Destins

class Address < ActiveRecord::Base
end
class EmailAddress < ActiveRecord::Base
end

[Rails] remote_form_for not passing form values

[Allen Walker]

I have the following:

<% form_remote_for :role, :method => :put, :url => {:controller =>
"roles", :action => "update", :id => @role.id\
}  do |f| %>
  
<%= select("role", "default_view", Account::ROLES) %>
<%= submit_tag("Update"); %> 

  
  

  
<% end -%>


Controller code:
 def update
role = Role.find(params[:id])
role.update_attributes(params[:role])
render :update do |page|
  logger.info "update: " + debug(params)
 end


the "debug(params)" outputs:

update: --- !map:HashWithIndifferentAccess
_method: put
action: update
id: "6"
controller: roles



There is no "default_view" field from my drop down. Just the params
passed on the URL string. Not sure why this is happening.

Thanks for any help

Sort it in the controller or model, wherever the find() is.  Often:

@upcoming_tour_requests = TourRequests.find(:all, :order => 'date')

Anything SQL accepts can go in the :order value, 'date DESC', 'id', etc.

Another point, blank? is for strings, empty? is standard Ruby for arrays.

I couldn't find a complete example of a double polymorphic

this using Google. It seems to be working so far, but I don't know if
I have everything setup correctly yet.

You'll want to do that when the data is marshalled, not in the view or 
parital code... look into the controller to see how your data is 
retrieved.

Then, the model whose is being displayed should be able to provide the 
data in the desired order...

[Rails] Making display options sort

[Ryan Ororie]

I'm doing some editing on an existing rails app and this view;
_tour_listing.html.erb looks like this:

<% if @upcoming_tour_requests.blank? %>
No upcoming tour requests.
<% else %>


  Group Name
  Contact Name
  Status
  Date
  Actions

<%= render :partial => "tour_listing", :collection =>
@upcoming_tour_requests %>

<% end %>
Other Active Tour Requests
Tour requests not scheduled to take place within the next two weeks,
but still having a status of initial, received, or confirmed:
<% if @tour_requests.blank? %>
No other active tour requests.
<% else %>


  Group Name
  Contact Name
  Status
  Date
  Actions

<%= render :partial => "tour_listing", :collection => @tour_requests %>

<% end %>

My question is with the render :partial => etc... line. I need to find
away to sort the data that is getting spit out by a specific field, how
would I do that?

[Rails] Problem with migration number

[Michael Satterwhite]

I have recently had to reload my computer. I don't know if this if
relevant at all to this problem, but wanted to mention it.

I have an application that I'm needing to make some changes to. To
prepare for it, I'm doing a new migration. In the db/migrate directory,
the last migration was 019_... My new migration is 020_...

The problem that I'm having is that rake seems to want to rerun
migrations beginning with 001. This causes it to error off. I've looked
at schema_info and schema_migrations in the database. Both have their
version set to 19.

What would be causing this? It would be a snap to go into mysql and just
do the migration manually, but I'd rather stay in the rails framework.

Thanks in advance

Git syntax for everyday tasks is so simple it really does not warrant a 
GUI.  Looking at past branches and merges, well there a gui like gitk 
has real value.

Create a new repository:
$ git init

Add files to stage:
$ git add 

Commit staged files to repository:
$ git commit -m"commit message"

Copy a repository:
$ git clone [://] 

Update and merge from a remote repository:
$ git pull ://

Update local commits to remote:
$ git push

Check local against remote:
$ git fetch

Look at local changes against remote
$ git diff

Unwind a local commit and preserve subsequent work:
$ git reset --merge

Abandon all local changes and reset to remote:
$ git fetch; git status; git pull
#all steps required in that order to place index in known state

Ignore files and directories:
$ vi .gitignore

The rest of it, and there is a great deal of material in the rest of it, 
is rarely used.  The supported protocols are git://, ssh:// and 
http(s)://.

[Rails] Re: Problem with disable_with

[Walter Lockhart]

Hi Klaus,

now I'm really confused.  When I remove the validation and use return
true:





It posts, no problem.

Any ideas?

Walter

[Rails] Using dom_id to localize testing.

[James Byrne]

I am trying to test a rails app using webrat.  I have this sort of
construct:

  

  

  Short Name
...


  Legal Name

  

  

<% for entity in @entities %>
  
<%=h entity.entity_name.titlecase -%>
...

   <%= link_to 'Show Entity', entity -%>

   <%= link_to 'Edit Entity', edit_entity_path(entity) -%>

   <%= link_to 'Destroy Entity', entity,
:confirm => 'Are you sure?',
:method => :delete -%>
  

I am trying to test the destroy link using this webrat code:

  my_entity = Entity.find_by_entity_name(
"my entity number #{row.hll_words_to_i}")
  within("body > table > tbody > tr#" + dom_id(my_entity, :list) +
 " > td#" + dom_id(my_entity, :delete)) do
click_link "Destroy Entity"
  end

This fails with a nil exception error:

  You have a nil object when you didn't expect it!
  The error occurred while evaluating nil.to_html (NoMethodError)
  /usr/lib64/ruby/gems/1.8/gems/webrat-0.3.4/lib/webrat/core/scope.rb:176:in
`scoped_dom'
...


I have tried with other variants of the selector.  If I check for the
selector using have_selector("td#" + dom_id(my_entity, :delete)) then it
passes.  If I use the long form above it also passes.  I test for a
missing selector then have_selector fails as expected. Therefore, I am
reasonably certain that the selector is indeed being found on the page.

Any ideas as to what I am doing wrong?

I guess you are using the has_many_polymorphs plugin.

[Rails] Re: Problem with disable_with

[Klaus Paiva]

You can always return false and inside the else block, add this
javascript that will submit the form:
document.forms["myForm"].submit();

[Rails] Re: How do I solve/debug "gem update" problem?

[LRaiz]

I am not sure what to look for in the output of "gem env" but here it
is
RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.1
  - RUBY VERSION: 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]
  - INSTALLATION DIRECTORY: C:/InstantRails2.0/ruby/lib/ruby/gems/1.8
  - RUBY EXECUTABLE: C:/InstantRails2.0/ruby/bin/ruby.exe
  - EXECUTABLE DIRECTORY: C:/InstantRails2.0/ruby/bin
  - RUBYGEMS PLATFORMS:
- ruby
- x86-mswin32-60
  - GEM PATHS:
 - C:/InstantRails2.0/ruby/lib/ruby/gems/1.8
 - C:/Documents and Settings/Leonid/.gem/ruby/1.8
  - GEM CONFIGURATION:
 - :update_sources => true
 - :verbose => true
 - :benchmark => false
 - :backtrace => false
 - :bulk_threshold => 1000
  - REMOTE SOURCES:
 - http://gems.rubyforge.org/

The only thing that appears a bit strange is the second line in GEM
PATHS because it points to my documents folder while I expected RoR
installation to be entirely self contained under C:/InstantRails2.0. I
have already tried deleting everything (is that the right way to
uninstall RoR?)  and unzipped everything again from
InstantRails-2.0.zip. Then I run "gem update --system" again and it
upgraded rubygems to 1.3.1. I also observed that this gem update
command added the second path to GEM PATHS (is it OK?). Now I am back
hitting the same wall; still can not update rails and at a loss.

Thanks for trying to help,
- LR

[Rails] Re: hashed password, send reminder email...impossible?

[mikhailov]

sure, you can't send the forgotten password. So, more secure way is to
store hashed password instead uncrypted one.
I usually send a password's reset link via e-mail.
I just publish an article with using before_on_create callback,
because is more useful way, which declare principe: Skinny
controllers, fat models.

[Rails] Strange Session Issue

[EddM]

Hey Everyone,

This is tricky. I'm having a very strange issue with a particular app
which, we think, is related to sessions. I'm afraid it's very hard to
explain, so if you would like anything elaborated on then please let
me know.

A user registers at my site, and activate their account. They attempt
to log in, and the system rejects their password, even if it's
correct. But, if the user then clears their cache/cookies (we're not
entirely sure which, because we can't replicate the error ourselves),
and then attempts with the same password they are logged in without a
problem.

It's possible that this issue is isolated only to IE users, as we have
only received complaints from them - although we have tried ourselves
in multiple flavours of IE with no problem.

I understand this isn't very well explained, so if you would like to
see any particular code please ask.

I thank you all in advance,

Edd :)

[Rails] Re: Versionning system

[Bobnation]

I haven't used the GUI that much, but I might take a look in the
future.

Personally, I happen to like CLI tools overall for many things. Even
though Textmate is still one of my favorite editors, there is
something nice about opening up VIM and using that for quick edit
jobs.

My opinion: try both! ;)

Awesome.  The ":include" option wasn't something I was aware you could 
use in a find for the model.  I knew this could be handled using a nice 
rails-like convention without having to code some convoluted sorting 
method.

That makes life much easier.  Thank you very much!

Okay. Looks like, you have config.plugins in your
RAILS_ROOT/environments/production.rb and hence backgroundrb isn't
getting loaded. If not that, are you using config.plugins in
environment.rb??

OK finally I got it sorted out.

[Rails] Re: Versionning system

[pepe]

Thank you to all of you.

I have been reading up about different tools and I was leaning towards
Git, among other things because of Github, as Robert mentioned. I
don't know much about the tool yet and I know there are 2 sides to it,
the shell screen and the GUI version. Is the same functionality
available in both areas, which one should I go with?

Thanks a lot again.

Got it. But if I were you, I'd create a new temporary rails projects, just
using sqlite3,. and try running your migrations there as a test. If they
work there, then there's something peculiar to your original config.

Caveat: I know zero about MS SQL Server so...

[Rails] Problem with disable_with

[Walter Lockhart]

Hi Group,

I have a registration.html.erb page with the following JavaScript at
the top which I use to validate form fields:





further down the page I have the form:

<% form_tag({:action => 'sendregistration'}, {:name =>
"myForm", :onSubmit => "return validate()"}) do -%>

Project Name: *<%= text_field 'email', 'projectname', :size => 30 %>
Project Type: *<%= collection_select 'email', 'projecttype_id',
@projecttypes, :id, :name, { :include_blank => true } %>
Region: *<%=
collection_select 'email', 'region_id', @regions, :id, :name,
{ :include_blank => true } %>

etc.

<%= submit_tag "Send", :class => "submit", :id =>
"mysubmit", :disable_with => "Please wait..." %>

<% end -%>

When I click 'Send' without the required fields the 'Send' button is
disabled and the text is replaced with 'Please wait...' which is as I
expected.  It also performs the 'validate' JavaScript function and
discovers that the required fields are not provided and displays a
popup window with the text 'You must fill in all of the required
fields!'

When I click 'Send' with the required fields the 'Send' button is
disabled and the text is replaced with 'Please wait...' which again is
as I expected.  However, the form does not Submit / Post, it just
hangs.

What am I doing wrong?  Would someone please help.

Thanks.

Regards

Walter

[Rails] SMF Forum + Rails - any experience?

[Mohit Sindhwani]

Hi, I'm trying to see if I can get Simple Machines Forum (SMF) coexist 
with a Radiant CMS site.  So far, I have only found this: 
http://railsforum.com/viewtopic.php?pid=49374 which gives some idea.  
Also, SMF exports out some data such as 'Recent Posts' that I should be 
able to parse and create some pages on that basis.

Now, my Radiant site needs login - not to manage the content, but to 
possibly post comments.  I was wondering if anyone has any experience in 
sharing user logins, etc. between SMF and Rails?

Any general experience with both?

Thanks,
Mohit.

Hi Franz,

Thanks, ive got a comments controller being used now, along with a 
partial link,

<% for message in @messages %>
<%= render :partial => @comment = Comment.new, :locals => { :button_name 
=> 'Post'}%>
<% end %>

this creates commments but without a message_id

so I need to somehow pass the message_id to the partial so that it goes 
into the database.

any ideas?

[Rails] Re: Trying to sort results of one-to-many relationship find

[Harold]

This is a plain association, no join table involved.

Try this in script/console and see if it solves your problem. The DB
can easily take care of the sorting:

orders = Order.find(:all, :conditions => '...', :include
=> :payee, :order => 'payees.last_name')

Then,

orders.each { |o| puts o.payee.last_name }

Hi Peter,

Many thanks for your extensive help on this one. I now have

@project_file = ProjectFile.new(params[:project][:uploaded_data])

in my projects controller.


  <%= f.file_field :uploaded_data %>

but it still says

 ActiveRecord::UnknownAttributeError in ProjectsController#create

unknown attribute: uploaded_data

[Rails] Re: polymprphic == confusion

[scott]

It looks like that is an option that might work, but is there a way to
do this without using single table inheritance?

Is it possible to do something like this in rails?

Owners
--
class User < ActiveRecord::Base
  has_many :contact_items, :through => :contact_links
  has_many :addresses, :through? => :contact_links?, :as?
=> :contact_items?
  has_many :...
end
class Business < ActiveRecord::Base
  has_many :contact_items, :through => :contact_links
  has_many :...
end
class Charity < ActiveRecord::Base
  has_many :contact_items, :through => :contact_links
  has_many :...
end

Double Polymorphic Join Model???
--
class ContactLink < ActiveRecord::Base
  # id:int
  # owner_id:int
  # owner_type:string
  # contact_item_id:int
  # contact_item_type:string

  belongs_to :owners, :polymorphic => true
  belongs_to :contact_items, :polymorphic => true
end

Contact Items
--
class Address < ActiveRecord::Base
  has_one :owner, :through => :contact_links
end
class EmailAddress < ActiveRecord::Base
  has_one :owner, :through => :contact_links
end
class PhoneNumber < ActiveRecord::Base
  has_one :owner, :through => :contact_links
end

[Rails] Re: There is already an object named 'schema_migrations' in the database

[Martin Hawkins]

Yes, I agree that the second migration seems to be trying to re-create
the schema table.

The database is a legacy SQL Server db with over 100 tables already in
existence.
I've noticed that db/schema.rb contains no information re the table
that was built, hence rake trying to re-create the schema_migrations
table.
The first migration created a searches table:
class CreateSearches < ActiveRecord::Migration
  def self.up
create_table :searches do |t|
  t.date :start
  t.date :end
  t.integer :team_id
  t.integer :match_id
  t.integer :innings_id
  t.integer :over_id
  t.integer :ball_id
  t.integer :match_session_id
  t.integer :bowler_id
  t.integer :delivery_type_id
  t.integer :extra_type_id
  t.integer :appeal_id
  t.integer :shot_type_id
  t.integer :runs_id
  t.integer :batter_id
  t.integer :umpire_id
  t.integer :validity_id
  t.integer :decison_id
  t.integer :height_id
  t.integer :extra_runs_id
  t.timestamps
end
  end

  def self.down
drop_table :searches
  end
end
 and the second migration tried to rename one of the columns:

class RenameTeamId < ActiveRecord::Migration
  def self.up
rename_column :searches, :team_id, :home_team_id
  end

  def self.down
rename_column :searches, :home_team_id, :team_id
  end
end

Dropping the whole DB is really not an option.

The mighty alias_method_chain (which is really just 2 calls to  
alias_method) can work here


class Plugin
   def do_something_else_with_rescue
 begin
   do_something_else_without_rescue
 rescue ...
 end
   end
   alias_method_chain :do_something_else, :rescue

That was the issue, I had "defaults" instead of :defaults.

[Rails] Re: How do I solve/debug "gem update" problem?

[Martin Hawkins]

I've had problems with upgrading gem in the past but they have
involved gem itself and not running it once installed.
Have a look at http://rubyforge.org/forum/forum.php?forum_id=28071 and
try re-installing.

Does 'gem env' give you anything out of the ordinary?

[Rails] Re: Problems with SQL Server 2008 and migrations using activerecord-odbc-adapter gem

[Ben]

Once I figured out how to use it, it usefully tells you its only
supported for SQL Server 2000 and 2005 databases.

rake db:migrate
rake aborted!
Currently, only 2000 and 2005 are supported.

So it looks like I'm on my own to try and fix activerecord-odbc-
adapter joy!

Unless any else knows of yet another adapter...?

It sounds like your second migration is trying to create the schema table
which already exists.

Maybe you could post your migrations, or at least the failing one?

Yes, the whole DB -- if you're wanting to fix a bad migration and run
it all from the beginning. That's not a bad thing early in a project.

[Rails] monkey patches to a method that exists in a plugin

[Tom M]

Say I have a plugin like so:

class Plugin
  def do_something
 do_thing :one
 do_something_else
 do_thing :two
  end
end

If I want to wrap the call to do_something_else in a begin/rescue
block, then it would seem that I need to either hack the plugin in
vendor/ or put a patch in lib/ that copies a portion of do_something.
Either way, it seems I lose on maintainability.


Is there a convention/method for monkey patching existing methods in
plugins in these situations?

Hassan,
Thanks for the reply.
No, I didn't edit an existing migration - I created a new one for the
rename.

I understand what you are saying about dropping the table (not the
entire db surely :-0). While that would work, I wouldn't get to
understand what the problem is!!

It sounds like you edited an existing migration -- if so, don't :-)

Create a new migration to change the column, or drop the entire DB
and start from scratch.

[Rails] Trying to sort results of one-to-many relationship find

[Corey Murphy]

Assuming I have two models:

Order "belongs_to :payee"
Payee "has_many :orders"

In the orders table, I store the payee_id.

If I want to pull all orders and display the list alphabetically by the
payees last name, what would be the best way to do it?

Would I need to setup a true "join" table and then run my find on it?  I
can't do this through the view using a sort plugin since that simply
changes the finders SQL and doesn't include the association logic needed
here.

Since I'm accessing the payee's name through the association
"order.payee.last_name" what is the best way to accomplish what I need
or do I need to write some convoluted method that breaks down the
recordset and orders it manually?

[Rails] There is already an object named 'schema_migrations' in the database

I've created a table in a SQL Server database using a migration,
successfully.
I've tried to change the name of a column in the table and got the
error message above when running 'rake db:migrate'.
Previously I have developed using MySQL and Sqlite and migrations have
worked successfully. This is an error I have not seen before.
Has anybody seen this and worked around it?

It is better practice to have a CommentsController to operate on your

of using the Messages controller.  I highly suggest that you then use

[Rails] Re: Dumb problem using BackgroundRb

[huard.el...@gmail.com]

hi,

the invocation in your controller should go
Middleman.worker(:my_worker).my_method(:arguments)
see documentation: http://backgroundrb.rubyforge.org/

btw I'm not using backgroundrb anymore, i got fed up with unclear
error messages and relative instability.  I'm now using workling-
starling for any new projects.

We use Mercurial because back in time the support of Git on Windows was 
bad. On Mac and GNU/Linux, Mercurial and Git are both excellent choices, 
so you won't be wrong. Don't use SVN, it's out of the game for new 
commers.
