[Rails] Helper to generate css-id from AR model. Do I have alzheimers?
On one of the many Rails projects I've worked on over the years, I seem to recall using either a helper or a method on a model to generate a css id based on the model class and id. It was very useful particularly in making views more testable in RSpec/Cucumber. I can't remember if this was part of rails, or from a plugin or something specific to the project.

The form_for needs to generate the right combination of url and http verb, and this depends on whether or not the comment is a new record. The form_for helper is designed to allow the same form to be used both for the new and edit views. Passing an array tells form_for that it's a nested resource. In this case, @post.comments.build will be a new record, it won't have an id until it's saved. Let's say that the id of @post is 42. Then the form should be set up to send a post request using the uri path 'posts/42/comments If it was the edit case then the comment would have an id, say 432, and you'd use something like form_for @post, @comment where the edit action in the controller set both instance variables, and the form would send a put request to the url 'post/42/comments/432' If you just gave form_for the single value @post.comments.build then it assumes that the comment resources isn't nested and it would post to the uri path 'comments' but the way the routes are specified this isn't going to work.

The latest, for which Sam Ruby took over the role of primary author from Dave Thomas, covers Rails 2.x and is the first to show timestamped migrations. In each of these the depot app has been brought up to the, then, current version of Rails. And there's a fourth edition in preparation which covers Rails 3.

I decided to just go with the soft copy, * It hasn't been mentioned, but the reason rails went from sequence numbered to timestamped migrations is that on projects with more than one developer it was not uncommon to have collisions over the numbering when different developers were working on different branches. Since it's highly unlikely that two developers will generate migrations at the same second, this goes a long way to alleviate the problem.

Fred,
I don't think that's the issue here. It seems to me that the problem
is the two-level STI
ShippingCharge
ContainerCharge
HandlingContainerCharge
ShippingContainerCharge
So, since ContainerCharge is an STI subclass, the association
has_many :container_charges
is going to add a where clause restricting the results to those where
the type is ContainerCharge.
I haven't tested it but perhaps
has_many :container_charges,
:class_name = 'ShippingCharge',
:conditions = {:type = %w(ContainerCharge
HandlingContainerCharge ShippingContainerCharge)}

Re: [Rails] Re: What happens when Rails 1.3.5 is installed on top of 2.3.5?
On Sat, May 22, 2010 at 2:47 PM, pepe p...@betterrpg.com wrote:
Just in case it applies here is an extract from the Pickaxe book
(Second edition, page 217):
Threre's a subtlety when it comes to installing different versions of
the same application with RubyGems. Even though RubyGems keeps
separate versions of the application's library files, it does not
version the actual command you use to run the application. As a
result, each install of an application effectively overwrites the
previous one.
That's actually not the whole story, and excerpt from the output of
gem help install:
Description:
The install command installs local or remote gem into a gem repository.
For gems with executables ruby installs a wrapper file into the executable
directory by default. This can be overridden with the --no-wrappers option.
The wrapper allows you to choose among alternate gem versions using
_version_.
For example `rake _0.7.3_ --version` will run rake version 0.7.3 if a newer
version is also installed.
The actual command you use to run the application is actually a bit
of boilerplate generated by gems which requires the gem and then calls
the executable in the bin directory of the gem. If you use that
_{version}_ option it requires a specific version of the gem.
So if you have both rails 2.3.5 and 1.2.6 installed then either
rails
or
rails _2.3.5_
will run version 2.3.5 which is the latest version installed. but
rails _1.2.6_
will run version 1.2.6
HTH
BTW, the OP gave rails version 1.3.5 as a example, as far as I know
this a fictitious version since rails went from version 1.2.6 to
version 2.0.0

Hi,
I'm on a mission to show my granddaughter how Pi can be computed. For

and precision for the moment).
bd = BigDecimal(0.141421356237)

So the extra set of parentheses I added don't capture the way I want
them to. I can do it using Ruby to generate a bunch of consecutive
\d{1,5} groups to satisfy my requirement, but some insightful Regexp
markup is preferable.
Any ideas?
Does this help?

Now rails looks for sample_log/sample.rb and finds it, and loads it, and then checks to see whether SampleLog::Sample is now defined, which it isn't because that file defined ::Sample instead.

I would trust the three of those guys before anyone who endorses Cucumber, any day of the week. I'm not a fan of dogmatism on either side. A few observations though: 1) I own every edition of AWDWR, including the latest version covering Rails 3. Each edition is an evolution of its predecessor. It started with test/unit and fixtures since that's what came with Ruby and was baked into rails. Although alternatives have appeared, the book has tended to stay there, probably because a) it's talking about what comes with rails, and b) it's easier not to rewrite sections when you don't have to. There are also pedagogical concerns. AWDWR is primarily an introduction to rails. Just like they teach physics in high school without recourse to calculus, doesn't mean that calculus isn't a very useful tool when you really start to practice Physics, some advanced topics are best left to later courses. 2) Rails 3 has refactored rails so that test/unit isn't closely coupled. If you install the rspec-rails and cucumber plugins, for example the rails3 generators will automatically produce rspec specs and cucumber features. Since the 4th edition of AWDWR is in an early beta form, I don't know how much Sam will cover this. Again, there's a certain amount of inertia. For one thing he has made and effort to bring testing earlier in the depot example, which I like. However he hasn't changed the flow to use test driven design, which is and should be standard practice for rails developers whether they are using test/unit, rspec, shoulda ..., I understand that just breaking up the testing chapter and reshuffling the chapters. It's better but it still comes across as fostering code first then test, which I doubt the authors fully endorse. 3) Fixtures. There are lots of experience Rails developers who have come to the conclusion that fixtures really s*ck. Hence all the fixture replacement plugins. In my experience, these days fixture replacements tend to be used much more than the built-in rails fixtures in real-world rails projects, not that there's much of consensus on which one is best. If fixtures work for you find, if not... 4) RSpec and Cucumber are seen as very powerful tools by a wide range of Rubyists and Rails app developers.

Re: [Rails] How to match dynamic named routes in Rails 3
On Tue, Apr 27, 2010 at 6:06 PM, Jury jurew...@gmail.com wrote:
Hi everyone,
I've been digging pretty deeply into the new routing capabilities in
Rails 3 and have been very impressed by what I've seen so far.
However, in my exploration I haven't been able to figure out one final
piece — it's a bit complicated to summarize, so here's a short example
of what I would like to do:
Let's say I've got a simple set of forums software, with a controller
named Forum. In the data model that Forum uses, there are a bunch of
topics with subtopics:
Foo
|--- Bar
|--- Baz
|--- Rick
|--- Astley
Although that's the way the structure looks today, there's nothing
that would prevent an admin from adding topics under Bar at a
moment's notice — so the main point is that the structure could
change.
I'd like to be able to write a routing rule such that I could match
http://example.com/Foo/Baz/Rick; to a specific action in the Forum
controller and know the order of the parameters that were passed in.
In a perfect world, I'd really only like to forward the request on to
the Forum controller if the path is sensible. I have some feeling
that I might be able to do something creative with :constraints, but
I'm not quite sure if I can pass in an appropriate method or proc that
would have access to the necessary data to do that check.
Can anyone out there with some better insight point me in the right
direction?
Well in Rails 2.x you could use something like this (from the rails
guide example):
map.connect 'photo/*other', :controller = 'photos', :action = 'unknown'
this would set params[:other] to an array of the path segments following photo.
I applied this thinking to Rails 3 routing, and added a route to a
version of the AWDWR depot app (I'm once again following that example
through the new beta version of the 4th edition). I put this at the
end.
match '*path' = 'products#forum'
I then added a forum action to the products controller which just
raises an exception so that I can see what the params are, and I get
this:
{path=products/forum/a/b/c}
So instead of breaking it down to an array it just gives you the whole string.
Some caveats.
1) Although the existing routes still work since I put this at the end
of the routes, unless this is the only controller you have you might
want to 'anchor' such urls with a first path component (e.g. forum).
2) Whether or not the fact that a 'globbed' route produces a string
rather than an array, might or might not be a bug in Rails 3.0.0.beta3
so it might change before release 1.

Don't you want :visits (with an s?)
has_many :visits, :conditions = year =
SQL_FUNCTION_THAT_RETURNS_CURRENT_YEAR,.
Replacing SQL_FUNCTION...YEAR with whatever works for your database.
If you want to specify the year, look into using a lambda for the
conditions...
I don't think you can use a lambda on the :conditions option to find/has_many...
but you can do it with a named scope
has_many :visits, :dependent = destroy
named_scope :this_year, lambda { { :conditions = { :year =
Date.today.year } }}
Then to get the visits this year for a model referred to by the variable model
model.visits.this_year
Alternatively, you could have a slightly different named scope which
would let you specify the year at run-time, assuming that @today might
not always Date.today, e.g. if you are using the user's timezone.
named_scope :in_year, lambda { |year| {:conditions = {:year = year}}
Then you could use
model.visits.in_year(@today.year)
The reason you need to express this a a lambda is twofold:
1) has_many and named_scope are evaluated in the context of the active
record class, so @today is not an instance variable but a class
instance variable, which is probably why it is nil.
2) more importantly, @today is being evaluated at the time the
association declaration is executed (during class definition time). If
you want to use the value at the time you make the query, it needs to
be a lambda so that the value gets evaluated each time.

That's how Rails keeps up with what migrations exist, and whether it's done them all. Running rake db:migrate:down VERSION=XXX should remove the entry. Otherwise rake db:migrate wouldn't run the migration again. A normal use case for migrate down is: rake db:migrate #oops something was wrong in migration 123456 rake db:migrate:down VERSION=123456 edit db/migrate/123456_whatever_it_does rake db:migrate On Tue, Apr 6, 2010 at 10:10 PM, GoodGets goodg...@gmail.com wrote: What exactly does rake db:migrate:down VERSION=XXX do? I understand that it runs the down migration, completely removing any columns/ tables that migration may have created, Well it does whatever YOU told it to in the down part of the migration. It's up to you (or whatever you use to edit/generate the migration) to write the correct code there. I tend to use Textmate snippets from the rails bundle to do migrations, and the table/column migration snippets will generate 'undo' code in the down migration when you expand them in the up migration. But YMMV depending on what tools you use. but does this mean that I can can delete these migration files as well? I'd like for Rails to have no knowledge of their existence. (I was allowing user profile pics with Paperclip, but have since decided to just use their Gravatars.) I know you can delete a migration, and even delete those columns from the schema, but Rails still remembers these changes and just updates them the next time you rake db:migrate. So, I'd like to completely rid my app of a particular migration, is rake db:migrate:down then deleting that migration from the migrate folder the way to do it? When you do rake db:migration the rake task looks for migrations under db/migrate which don't have entries in the schema_migrations table, and runs those (actually I think it's a bit more subtle than that, there's been discussion of a 'bug' which can make the task ignore migrations with a timestamp older than the newest one in schema_migrations, which can keep migrations merged from another branch NOT to be run. But... If you run rake db:migrate:down version=XXX and then remove the file db/migrate/XXX_whatever from your source, the rake task won't see it and it will be gone. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Github: http://github.com/rubyredrick Twitter: @RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Did you add the association declaration:
belongs_to :code, :foreign_key = activity_type
to the Activity class?
That says that the activities table has a foreign key field called
activity_type which is the key of a record in the codes table.
And it creates the association called code which the error message is
complaining about.

Re: [Rails] Upgrading rails project - version 1.2.6 to current (2.3.5)

The project is pretty much vanilla code and does not use plugins. Are there scripts that can do the job (or pull out incompatibilities).

Reason for wanting to upgrade is that I now do want to add features and start using plugins and of cause a lot of the plugins that I would like to use require rails 2.3+ First, I'd recommend doing this in steps, first upgrade to Rails 2.0, then 2.1, then 2.3.5 Why? Rails 1.x to 2.0 was a pretty big change, for some apps 2.0 to 2.1 was even bigger because of some subtle and significant changes to ActiveRecord.

Googling for rails upgrade, flushed out this article on the first step, more specific searches are likely to find articles on the others: http://www.sitepoint.com/blogs/2008/01/25/upgrading-to-rails-20-a-recipe/ It includes a pointer to a rake task written by Geoffrey Grossenbach (of Peepcode fame) which find stuff deprecated in 2.0.

AR will generate:
SELECT pages.id, pages.no FROM pages INNER JOIN books ON books.id

So the join has already been done. Wouldn't :include make a redundant

Then just change the joins to include:
Page.all(

:conditions = [books.library_id = ?, 1]
)
Which will both allow you to refer to the books fields in the where

I've tried with class_eval in the plugin, but can't get it working.
I'm calling acts_as_item(options), and that method can see the options
passed from a model. Then inside the class_eval, I'm adding a method
(def self.configuration) which returns the options hash. I thought from
an instance, I'd be able to do instance.class.configuration which would
then return said options hash.
Any ideas?
thanks for reading.

def self.included(base)
base.extend ClassMethods
end
module ClassMethods
def acts_as_item(options = {})
configuration = {:option=:value}

I think you want this to be
def configuration
Since this is in a module extended by the class.

For a selection criteria say I wanted to search for every title starting on Monday, Wendsday and Friday where each day on the selection screen would be checkbox representing the days Monday - Sunday and Everyday (clicking everyday would remove the checkboxes should someone select everyday and a day of the week) What would the active record query look like to dynamically pass in the days of the week selected should say mon, wed and fri get selected given that what they selected is past to the controller in a days_of_week variable. I'm not totally tied to the idea of storing the day as a number so if anyone has any better implementations of this I'm listening. Something like # get weekdays_selected to be an array of the numbers corresponding to the checked boxes plus 0 # For example if you wanted to find events on Mondays and Wednesdays, weekdays_selected should be: # [0, 2, 3] Items.all(:conditions = [weekday IN ?, weekdays_selected]) or if you're using Rails3 Items.where(weekday IN ?, weekdays_selected) If it were me I might think about tweaking this a bit and use 7 instead of 0 for any day, since Ruby's Date and Time use 0 for Sunday through 6 for Saturday.

Re: [Rails] Re: how to validate uniqueness across multiple columns in ActiveRecord?
On Mon, Feb 22, 2010 at 4:54 PM, Grary grary.sti...@gmail.com wrote: Thanks Fred. What do you mean by 'use a unique index'? What I am concerned about is logical uniqueness, i.e., persist only data objects with a unique combination of attributes. So if I understand correctly, lets say there are two attributes a, and b You want to make sure that no two models have the same COMBINATION of values for a and b, so having two models with: a = 1, b = 2 a = 1, b = 3 would not be a conflict If that's the case then the standard validation class Widget ActiveRecord::Base validates_uniqueness_of :a, :b end wouldn't work since it tries to prevent saving two models with the same value of a, OR with the same value of b And even if that's not what you're trying to do, and you're ok with the example being a conflict, Fred's point is that validates_uniqueness_of doesn't guarantee uniqueness if two users try to save conflicting records simultaneously. The validation works by first trying to find a record with the value, and if it doesn't find it inserting the 'new' record, and this can fail due to a concurrency hole. To fill this hole requires leaning on the database server, and the way to do that in SQL is by having a unique index on the table which covers the column or columns you want to be unique. This assume you are using a database which supports it, e.g. MySql. To create an index you can create a migration which includes a statement like add_index :widgets, [:a, :b], :unique = true) Assuming that the table name for the model is 'widgets' Now if you do this, you also need to be aware that if you try to save a record with a uniqueness conflict the save will raise an ActiveRecord::StatementInvalid exception, which you'll need to rescue and do something like telling the user of the conflict so that he can resolve it. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

No. You don't really want any code in your view, other than the very
bare minimum. Sounds like you want to put a l lot of this in a view
helper
Thanks for prompt reply, I don't want to put any more code than that.
Just want a simple change of CSS style depending which page is being
displayed at the moment.
Well you already have WAY too much code in the view, and that code
deals with stuff like urls/routing which really shouldn't be the
business of a view.
The way I approach the issue of highlighting the active tab (which it
looks like is what this code is trying to do, would be to have a
helper to generate the html, which uses either the controller name (if
there's a one-one correspondence between controllers and tabs) or a
current_tab instance variable set by the controller. And the helper
should use path/url helpers rather than coding absolute uris.
So something like this.
First make sure that routes.rb has a sensible routing for the various
urls. Just an example:
map.home '/', :controller = 'welcome', :action = 'show'
map.how_we_work '/how_we_work', :controller = 'welcome', :action =
'our_process'
map.contact_us 'contact_us', :controller = 'contacts', :action = 'index'
Note that these route are just for example purposes, I'd probably do
it quite differently, but that's not relevant to the current problem.
In fact, the whole point is that the routing is something which might
well change over the life of the app, and that's one of the things
which makes view code like your starting point fragile.
Then in the controller(s) in the action methods which handle the
various end points
class WelcomeController ApplicationController
def show
@current_tab = 'Home page'
end
def our_process
@current_tab = 'How we work'
end
end
class ContactsController ApplicationController
def index
@current_tab = 'Contact Us'
end
end
in a helper, probably application_helper.rb
def tab_link(tab_name, target)
link_to(tab_name, target, :class = tab_name == @current_tab ?
'current_tab' : 'jtab')
end
def navigation_bar
[
['Home page', home_path],
['How we work',how_we_work_path],
['Contact Us', contact_us_path ]
].map {|tab_name, target | tab_link(tab_name, target)}.join(\n)
In the view:
%= navigation_bar %
Again this is probably not exactly the code I'd come up with, but it's
close to what you started with and adheres much better to what the
responsibilities of routes, controllers, and views should have in a
Rails app. IMHO

Unlike some of the other responders, I'm going to take your arbitray
objects to mean that they aren't necessarily ActiveRecord models, and
therefore SQL solutions don't apply. Assuming that each of these Ruby
objects has a method date which returns either a Date, DateTime, or
Time object then something like
@things.group_by {|thing| thing.date.to_date.beginning_of_month }
while return a hash whose keys are the dates which have at least one
thing, and whose values are arrays of things whose dates fall within
the month.
If you know that the things all will return a Date from .date then you
can leave out the to_date in the expression.
def initialize(date)
@date = date
end
attr_reader :date

No. Strictly speaking, helper methods ought to be called helper functions as they are not attached to specific objects. No, helper methods are indeed methods.

If this were not the case then the helpers couldn't reference view/controller instance variables, which they can. The OPs question was why duplicated method names weren't resolved according to some perceived inheritance hierarchy. The resolution just follows standard ruby semantics. 1. First look for a singleton method in the receiver object. 2. If that fails look for an instance method defined by any modules which the object extends, in the reverse chronological order of extension. 3, If that fails set the class to examine to the class of the object 4. look for an instance method in the class to examine 5. If that fails look for an instance method defined by any modules which the class to examine includes, in the reverse chronological order of inclusion. 6. If that fails and the class to be examine has a superclass, set the class to examine to that superclass and go to step 4, otherwise send a method_missing to the receiver object. Now normally, a controller will include the helper(s) associated with it's superclass (usually ApplicationController and therefore ApplicationHelper), and the helper associated with itself in that order. But this default can be change using the ActionController::Base#helper method (which in Rails 2.x is actually defined in the module ActionController::Helpers.

No, I don't think that this will work given the database schema described.
Widget belongs_to :owner
Owner has_one :widget
means that the widgets table has an owner_id colum , the owners table
doesn't have a widget_id field.
The has_one relationship is really just a has_many which adds a limit
of 1 to the query.
@owners = Owner.all.reject{|o| o.widget.nil? }
Would also do it. This has the drawback that the DB is going to return
*all* the owners and then filter them in ruby. Won't be as speedy as the
first option.
This will work, but as you point out it can be inefficient if there
are a lot of owners.
While it's possible to get this down to a single SQL query with the
given db design, using an outer join and a carefully crafted
conditions clause, it might be simpler just to reverse the
relationship, as long as there is really a 1-1 cardinality
relationship, it could just as well be
Owner belongs_to :widget
Widget has_one :owner
with the concommittant db table changes.
Then
@owners = Owner.all(:conditions = 'widget_id IS NULL')
would work.

Re: [Rails] Pure, OpenID-only (password not a choice) Authentication?
On Sat, Jan 9, 2010 at 5:32 AM, Audrey A Lee audrey.lee.is...@gmail.com wrote: Hello list, Are any of you using OpenID to register and authenticate your users? I have found 2 projects on github which mix Rails with OpenID: http://github.com/tsechingho/authlogic_bundle http://github.com/binarylogic/authlogic_openid Both projects seem suited for providing a choice to the end-user: - Vanilla password based authentication - OpenID based authentication I want to implement the use-case where the end-user is allowed only OpenID based authentication. Some end-users are completely confused by the idea of having 2 ways to authenticate. And even the smart ones bump into a problem. They register, and then return in a month and forget if they were using a password or OpenID. So, I want to make it easy for them. They use OpenID or nothing. Actually, I want to make it even simpler: Yahoo-OpenID or nothing. Anyway I did the obvious thing. I tried to remove Vanilla password based authentication from each of the above projects. I ended up with 2 piles of broken software. So my question is, do you know of any projects or Rails starter kits which implement OpenID-only authentication? No I don't. And I believe that the openid advocates don't recommend this. The problem is that if the user's open id server is unavailable for whatever reason, he/she can't log in. Providing a password option for authentications is the openid equivalent of a 'forgot my password' mechanism. Just some food for thought. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Twitter: http://twitter.com/RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Re: [Rails] Re: fields_for

I am just learning how to use 'fields_for' so forgive me if I sound
like I don't know what I'm talking about.
My understanding is that 'fields_for' will iterate through the
collection, hence working with one element/object of the collection in
each iteration. If I need an attribute from the element/object at each
iteration, how would I know which element to access with
@my_object.my_collection? I don't even know if there is an index I can
use to get to the element I need as in @my_object.my_collection
[my_index], hence allowing me to do something like:
No fields_for doesn't do any iteration. It's used for setting up a
scope for one or more form fields for a different object than the one
which scopes an outer form_for
From the doc:
% form_for @person, :url = { :action = update } do |person_form| %
First name: %= person_form.text_field :first_name %
Last name : %= person_form.text_field :last_name %
% fields_for :person do |permission_fields| %
Admin?: %= permission_fields.check_box :admin %
% end %
% end %
So just like form_for doesn't do any iteration, neither does fields_for.
Since you haven't told us any more about what you want to do, I don't
know how to help any further.
