Yes, this trick stopped working in 2.2 because the reflection
now caches its conditions SQL.
One workaround is
reflection = reflect_on_association(:current_user_vote)
reflection.options[:conditions] = "votes.user_id = #{holder}"
reflection.instance_eval { @sanitized_conditions = nil }

That's a useful trick to know. An alternative I've been using is to dynamically change the :conditions option of association reflections. The advantage is that it works for all includes rather than just the last include, but the disadvantage is that it's not thread safe, unless you put a lock around the query.

If you don't want the browser url to change, you can just call the other action like a method, passing the parameters in either an instance variable or a method parameter (that's default nil to allow it to be called externally). Or are you messing with params directly? This is assuming the other method is in the same controller. If it isn't, you'll have to make the other method available within the first controller, either through inheritance or mix-ins. -- Rails Wheels - Find Plugins, List & Sell Plugins - http://railswheels.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

That sounds like a good idea. Perhaps a
:log => :instance_variable_name option to find.
One alternative is the query_trace plugin that displays
a backtrace for each query, so that the log shows what
line of code is associated with each query.

Yes, that's the way Transactions (now) work. The correct way to handle this is to not proceed with a transaction unless all model instances being saved in that transaction have been validated.

:update changes the innerHTML of a node, so you will be inserting
the table inside the table tag.
Wrap a div around the table and update that instead.

Rails automatically wraps saves in transactions, but does not
reset the ids of successful saves within a rolled-back save,
even though those saves will themselves be rolled-back.
You'll have to do something like
@page.save_without_transactions
or save your photos outside the page save.

Perhaps something like:
module ContactService
def self.set_account(url, key)
Thread.current[:api_conn] = ApiConn.new(url, key)
end
def api_contact_add(data)
Thread.current[:api_conn].api_perform('ContactService', 'add', data)
end
end
before_filter do
ContactService.set_account(
"#{current_account.api_url}.application.com", current_account.api_key)
end

Since you're using observe_form, params[:name] will be set
in your controller action, which can be used in the view.
e.g. :foo => params[:name]

You will need to send this value as a parameter of your AJAX
call, using the :with parameter of the form helper.

Put these in Admin and OrdinaryUser sub-classes/sub-models of your
main User model. If you add an STI "type" field to this model then
both these models will still use the users table if you properly
instantiate them.

Adam, the usual way this is done is with the nested-set data structure, which effectively also uses btrees in the DB index for the "left" column. Searching by pattern match would be somewhat slower than such indexed nested-set searches. Your method does have the advantage of being able to add children without having to fix-up the tree afterwards, and for giving each node a permanent hierarchy identifier that makes it easy to do subcategory searches in search-engine indices. The nested-set method can however be tweaked to have the same properties. -- Rails Wheels - Find Plugins, List & Sell Plugins - http://railswheels.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

A non-thread-safe solution may be:
after_save 'attachment_options[:thumbnails] = Thumb.get_thumbs(style)'
has_attachment :content_type => :image,
:thumbnails => Thumb.get_thumbs('landscape')
but a better solution may be to add PortraitPhoto and LandscapePhoto
sub-classes.

Note that you want all-or-nothing DB updates, but, for purposes of form redisplay, always want both in-memory attribute updates and validity-checking done on each. Here's how: 1. Update attributes on each without saving using the attributes= method. 2. Call valid? on each, storing each result in a local variable. 3.

However that's not the problem here. You get the same behaviour if you use steps[0]. Looking at it again after some sleep, I see that the different b object is actually loaded at the "a.steps << b" line. That is, the object is added by updating the foreign key in the database, loading the collection, then folding in any new_records, which ends up giving you the different b from the database.

Yes, I would regard this as a Rails bug.
The clear method is not setting the foreign key to
nil on the in-memory object.
It's only being manifest though because of the
unnecessary saves you're doing, meaning that
the problem has probably been rarely seen.

Your MySQL session is timing-out after the default 8 hours. Either increase the timeout by adding the following line to the [mysqld] section of the /etc/my.cnf file: set-variable = wait_timeout=<#seconds> or you can instead insert a call to ActiveRecord::Base.verify_active_connections! ahead of any database queries. The verify_active_connections! method is called by Rails before every request, but your backgroundrb process will not be getting this constant hammering to keep its database connection alive. -- Rails Wheels - Find Plugins, List & Sell Plugins - http://railswheels.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Is this with a recent version of Rails?
At one time you had to do
layout proc {|controller| 'some_layout' unless controller.request.xhr?}
But if you're doing proper RJS renders, I don't think it's now necessary.

Whoops, you'd need to add the prefix /path/to on these

Yes, you could use a recursive (tree) or batch (nested-set) traverse.
Or could actually do it in one statement, like
os = sanitize("/#{old_name}/")
ns = sanitize("/#{new_name}/")
Person.update_all "key = replace(key, #{os}, #{ns})",

What you really need to look at is not the params hash,
but the string posted by the browser. See this by adding
"logger.info request.raw_post" to your controller action.
If the parameters are indeed posted out of order, then the
problem was with the missing td tags. However a correct
order would instead suggest a bug in Rails' parameter processing.

It does require maintenance: whenever a name changes you have to
update the string in all children and all ancestors.

First-generation children are efficiently retrieved in both
better_nested_set and acts_as_tree via the parent key.
better_nested_set also allows you to efficiently retrieve all
generations of children using the all_children method.
So your current method will be making one DB call per
generation. And you should put the name match into the
SQL conditions rather than in a Ruby loop.
But have a look at the code in my last post. It can find
the correct Bart using only one DB call by matching
up the unique ancestors chain.

Put something like this in a file in the lib directory:
class ActiveRecord::Base
def self.blacken_attrs(*attrs)
before_validation <<-END
#{attrs.inspect}.each do |attr|
if v = send(attr)
v.strip!
v.squeeze!(' ')
end
end
END
end
end
Then in the Phrase model write
blacken_attrs :word, :second_word, :third_word

Efficient retrieval of all descendants or all ancestors
of a record requires the addition of nested-set capability.
One alternative is to make the ancestor array a string key
to each record ("abe|homer|bart"), allowing instant retrieval.
Another would be to build the sql iteratively:
ancestors = %w(abe homer bart).reverse
conds = {"people.name" => ancestors.shift}
joins = nil
ancestors.each_with_index do |name, i|
joins = joins.nil? ? :parent : {:parent => joins}
conds.update("#parents_people#{'_' + (i+1).to_s if i!=0}.name" => name)
end
bart = Person.find(:first, :conditions => conds, :joins => joins)

The test I did was to post from the following view.
On Rails >= 2.1 I got the correct
"recipe"=>{"ingredient_lines"=>[{"ingredient"=>{"name"=>"hhh"}}]}
on 2.0.2 I got what you're seeing:
"recipe"=>{"ingredient_lines"=>[{"ingredient"=>{}}]}
You may like to run the same test.
If you see the same, perhaps the problem manifests when extra
parameters are added. You can try adding fields until you
are posting your complete form. Please post what you find out.

I believe this is a limitation of Rails' parameter parsing.
It can't handle more that one level below an array parameter.
A solution is to create an ingredient_name accessor in
IngredientLine, and arrange to have this rendered and posted.

You have to make sure Ruby sees two separate hash arguments:

:class => 'monthSelect' %>

I don't think what you need can be formulated into normal has_manys.
You'll either have to use the has_many :finder_sql option that
includes joins to the players and teams tables, allowing you to
add the appropriate SQL conditions, or you can keep visitor_stats
and home_stats as methods, but have them call find:
def home_stats
player_stats.find :all, :select => 'player_stats.*',
:joins => {:player => :team},
:conditions => "teams.team_code = #{home_team_code}"
end

You can try
require 'socket'
REAL_PRODUCTION = Socket.gethostname == 'mysite.com'
or
hostinfo = Socket.gethostbyname(Socket.gethostname)
hostnames = hostinfo[1] << hostinfo[0]

All the date_days fields will be selected by default,
the "date" field being available in each result as
event_date[:date].
You're in trouble if this conflicts with an EventDate
attribute, because Active Records has ignored the
find :select option when eager loading is used (though
I'm not sure whether this is still the case for Rails 2.2).
A patch is available for Rails 2.0.2 that allows :select
to be used in these circumstances.
Are you sure you want to use a right join? This could
give Active Record trouble.

Integer hash values aren't stored as object references.
Perhaps your problem is that you're not re-initializing
video to {} each time around the loop, so you're always
updating a common video object.

Tricky, but investigate something like:
class Phrase < ActiveRecord::Base
has_one :top_ranked_definition, :class_name => 'Definition',
:conditions => <<-END
definitions.rank =
(select max(rank) from definitions where phrase_id = phrases.id)

Like you, I've used the sleep hack, because ActiveRecord doesn't currently have after_commit callbacks. The only other solution would be to move the remote call to your controller, after the transaction block or save call. You can still leave the details of the remote call in the model, but just call it from the controller. -- Rails Wheels - Find Plugins, List & Sell Plugins - http://railswheels.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If the email sender is common to all mailer methods

Yes, it's possible to eliminate the explicit validity checks and jump straight into the transaction, allowing the validations to happen automatically during calls to save! or update_attributes!. The disadvantage of this is that if the second object saved is invalid, the save of the first object has to be rolled-back, which is significantly slower than checking the validity of both before hitting the database. You also have to add that rescue block to ensure that the validity of the second object is checked for purposes of form error display. -- Rails Wheels - Find Plugins, List & Sell Plugins - http://railswheels.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
