[Rails] Re: Apply style in collection_select ?????
Hi,
Try this:
<%= collection_select(:customer, :country_id,
@countries, :id, :country, {:style => 'width:100px;', :onchange =>
"updateState('');", :id => 'country_id'}) %>
Argument list is:
name of instance variable (@customer becomes the symbol :customer),
name of attribute (@customer.country_id becomes :country_id), then the
array of objects (@countries), then the id method to send each of
these (ie send them all "id" to get the id of each object), then the
display method ("country" in this case, which seems a bit odd to me,
it'd probably be name rather than country... ), then a HASH OBJECT
(represented by {} braces) which has html options in it.
The html_options= simply assigns a temporary variable to be the
hash... so you don't need it, because you're not using it elsewhere.
Good luck!

[Rails] Re: Missing Image RoutingError = TOO SLOW
Write a helper that wraps image_tag that checks to see whether you are
on your production box. Iff you are on the production box, then
image_tag it is, otherwise, some placeholder image guaranteed to be
local in your images dir.
Will that work?

[Rails] Missing Image RoutingError = TOO SLOW
My development setup gets its data from our production database, and
this production database refers to a bunch of images that aren't
available on my local machine, thus when running development I get a
large number of Rails RoutingErrors, which I don't really mind.
What I *do* mind is that catching every one of these errors takes
about 2-4 seconds, even with my quad-core desktop. If I try to load a
page with 5 missing images, it will probably be 20 seconds before I
can visit another page.
Has anyone else experienced this and thought up a clever workaround?
I had hoped that using
rescue_from(ActionController::RoutingError) { |e| render :nothing =>
true }
in my application controller would fix it, but it just serves to make
the exception not print out its text. It still takes the regular
amount of time per image for the exception to be caught and ignored.
Thank you greatly for any insights into how I might improve this.
Bill

All applications insert their "to send" emails into the message queue (database table) and a regular job starts up and reads in the details and tries to send them. If it manages to send it, it cleans up for this record (i.e, deletes the item from the table and/ or informs someone). If it doesn't manage to send the email, it increments some sort of "retry count" in the database and waits again. If a message fails to go after a certain number of tries, it simply marks the message as undeliverable and removes it from the message queue to a "failed items" database. Now, I wonder if there is a message queue implementation in Ruby that does this?

[Rails] Re: request.env variables in an observer
> I have a scenario were I would like to inject the IP address and > UserAgent into an email when a database record is saved. You need to trap the remote_ip and user_agent from the request method in the Controller instance for that request. That is where this information is received. Then you need to have this information available in the Active Record instance where the save is happening. One way to do this is to use the Thread class since both operations are ocurring on the same thread. There is a Thread.current object that you can stuff the info you need. In your application.rb controller file: class ApplicationController < ActionController::Base before_filter :log_ips private def log_ips Thread.current['remote_ip'] = request.remote_ip Thread.current['user_agent'] = request.user_agent end end Then somewhere your rails load path, either in lib or your models directory, add an active record extension. module ArExtension def self.included(m) m.class_eval do after_save :log_ips end end def log_ips puts Thread.current['user_agent'] # do you really want to email every request? you might want to do something else puts Thread.current['remote_ip'] end end ActiveRecord::Base.class_eval do include ArExtension end Hope that helps. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: How to share tables between Ruby Apps...
> How can we share this > table(email details) across several Ruby apps? Sharing a table is straight forward. If they are in the same database, you simply call the class methods for this utility functionality. If the table exists in another database, you add that database to the database.yml file. More importantly however, you want to avoid code duplication. You do not want to duplicate the code that looks for unsent emails in all your apps. You have several options. The first ones that come to mind are: 1. Write a utility rails app that does the looking for unsent emails and sending. All your other apps simply write to the table that stores these unsent emails. With this approach you can build views that allow you to see the queue, etc of all the emails, regardless of the app. 2. If you prefer to have the methods available in each app, then you want to look at the plugins facility in rails. You can write a plugin that gets used by all your apps. Then each of your apps gets the plugin from the same repository. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

: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.

It is probably best for you to handle this via a load script or a rake task. As to the file upload, if you are using a plugin like attachment_fu, then you are all set. Take a look at the plugin tests directory to see how those simulate the upload of files and create the uploaded files either in the db or in the path you specified in your models. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] ajax search feature works in FF but not IE
Hey All,
I put a simple search box on my projects/index view, via the following
observe_field call:
<%= observe_field('project_search',
:url => { :controller => "projects", :action => "index_search"},
:update => "project-list",
:loading => "Element.show('search_spinner')",
:complete => "Element.hide('search_spinner')",
:frequency => 1,
:submit => 'search') -%>
The index_search action queries out the proper set of projects & renders the
list to a partial, like so:
def index_search
min_query_length = 1
q = params[:project_search]
if q.length > min_query_length then
@projects = Project.find_by_name_fragment(q) || []
else
order_by = params[:order_by] || 'statuses.name'
@projects = Project.find(:all, :order => order_by, :include => 'status')
end
respond_to do |format|
format.js do
render :partial => "project_list.html.erb"
end
end
end
That partial renders a table w/one row per project. This works just fine from
FireFox. But from IE I don't get my table--just a blank page. So the records
that used to be in my table id="project-list" are gone, but I don't see the new
ones that index_search queried out of the db. Judging from the log, IE is
indeed making the request to index_search, passing the params it should, etc.
The log even says, e.g.,
Rendered projects/_project (0.01600)
Rendered projects/_project_list.html.erb (0.10900)
But IE doesn't seem to want to actually *display* these guys. FF's web
development toolbar tells me I'm in "standards compliance mode" when I pull up
a searched list of projects, so I believe the markup is all kosher.
What am I doing wrong?
Thanks!

What follows the sts portion in your string? Is it something like
"sts-123-foo" or "sts-123?foo" or something? You need to figure out
what that character is and then add it to the regular expression. Or
if it's nothing and that's the end of the line anchor it with '$'.

I think you are getting your associations mixed up. In addition to the has_many and belongs_to associations, you can also have a has_and_belongs_to_many. to use that one you would do this: class User < ActiveRecord::Base has_and_belongs_to_many :lists end class List < ActiveRecord::Base has_and_belongs_to_many :users end and then you have a joining table, that if you stick to conventions, you call it: lists_users - user_id - list_id That is the simplest way to handle this, assuming you do not need to store any details about the membership. Now if you need to store more details about the membership, then you would have three classes: User, List and Membership class User < ActiveRecord::Base has_many :memberships end class List < ActiveRecord::Base has_many :memberships end class Membership < ActiveRecord::Base belongs_to :user belongs_to :list end Hope that helps.

I'd go with <%=t "User" %>.
:User works in this case because t() is converting the argument to a
string and :User.to_s => "User". :User.Username won't work because
there is no "Username" method on the *symbol* "User".

I'm having trouble following your logic.
Parent < ActiveRecord::Base

Child < ActiveRecord::Base
belongs_to :parent
end
A parent has many children and each child belongs to one a parent.
parent = Parent.find_by_name("Bill")
parent.children.count

parent.children.build(:name => "Steve");
parent.children.count
=> 1
steve = parent.children.find_by_name("Steve")
steve.name
=> Steve
Database:

parents
|id|name|

children

It all make perfect sense to me.

Look up how to serialize a Hash into a :text field. If you don't need to query a database by a field, you don't need the full overhead of a field type. To give your users abstract data, let them enter keys and values into fields that expand forever, and then AR will serialize them.

[Rails] newbie testing: xml_http_request and route, route not recognised
In my view the generated html has this, and it works just fine: delete So in my functional tests I tried the following and it tells me the action isn't recognized, as if it isn't translating the :delete method to the destroy action in the controller : xml_http_request :delete, person_movie_path(movies (:one).person_id,movies(:one).id) "rake test" gets me : test_delete(MoviesControllerTest): ActionController::UnknownAction: No action responded to /people/ 520095529/movies/953125641. Actions: create, create_guid , delete_more_than, destroy, edit, edit_person_movie_path, exception, exception=, index, log_for_stats, log_login, new, redirect_loop_or_default, referrer_url, rescue_action_without_handler, save_referrer_to_cookie, store_loop, and update I'm a bit perplexed. googling didn't get me any clues. The route is correct, I think. See this pastie http://www.pastie.org/372719 if you think my movie routes may be up the spout. Any ideas?

Muchas gracias, that is close to perfect. The only problem is if I hit
"Preview Post" multiple times, it keeps adding onto body, but I can fix
that problem.
It's times like these that I realize I need to learn more javascript.

[Rails] saving ActiveRecord/Form data changes??
Greetings everyone,
This post has been moved (on suggestion) from the Ruby forum.
I can't pass updated/changed values from the form elements to the
ActiveRecord. However something is going through because the table's
update_when column is registering the date/time of the update, but
otherwise no data revisions to other columns transpire. Have tried
using form_for helper as well, but the same results.
This is all new to me, so not sure what additional info will be
relevant. But am using Ruby 1.8.6 with a local MYSQL 5.1 database thru
a Radrails IDE. My apologies for whatever info I have ommitted. Any
suggestions on where I have gone astray will be most appreciated.
Thanks, Bill
CONTROLLER:
class FileController < ApplicationController
def edit
@file = File.find(params[:id])
end
def update
@file = File.find(params[:id])
if @file.update_attributes(params[:file])
redirect_to :action => 'show', :id => @file
else
render :action => 'edit'
end
end
end
VIEW:
<% form_tag (:action => 'update', :id => @file.id) do %>
Description
<%= text_area 'file', 'description'
<%= submit_tag 'Save changes' %>
<% end %>
<%= link_to 'Back', {:action => 'list'} %>

has_many :foo, :class => 'User' only says "find a model called User, and expect
it to have a user_list_id pointing to us".
To distinguish moral relevance, use:
has_many :naughty, :class => 'User', :conditions => { :morality => 'naughty }
Less mind-reading on AR's part - it was not going to guess that User.naughty
had
a relationship with UserList#naughty, unless you specify that.

[Rails] Re: How to pass current value of form field in link_to?
Man, maybe I am making this more complicated than it should be.
I just need to pass whatever is in the text_field to a "preview" action
when I click a "preview" link. So I don't really need to dynamically
update anything, but when "preview" is clicked, I want to get what is in
the text_field and pass it to my "preview" action.
To make it clearer, when someone clicks "Preview Post", I want @body to
be set to whatever is in the text_field.
<%= link_to "Preview Post", {:action => :preview, :id => @topic.id,
:body => @body}, {:id => 'link', :target => "_blank"} %>
Any ideas?

[Rails] ActiveRecord: Least surprise? Really?
OK I AM new to RoR, and I have more experience with Java and straight SQL. So maybe I'm just so used to thinking in a way that is anticipating more than "least" surprise. Anyway, here's what surprised me: If I have an object that belongs to another object, I would expect the parent to have the FK to the child, not the other way around. Why? Because if I were to do it in memory (forget about persistence for a minute), it would like kinda like this: p = Parent.new p.children << Child.new Now in this example, p has an array of children (as in, it HAS MANY). If I wanted to do a two-way relationship, I would do: p = Parent.new c = Child.new p.children << c c.parent = p In this case, the parent has an array of children (literally a list of many references to its children), and the child has a single reference to a parent (assuming an xml-like hierarchy here, not a family-tree type hierarchy). Anyway, when I create a "has_one" association, I would expect this object's table to literally have a FK column for the "child" object. When I create a "belongs_to" association, I would expect the same thing. When I create a "has_many" association, I would expect a fact table "parent_child" to be created (with id, parent_id, and child_id columns), and if I wanted a two-way relationship, I would add "belongs_to" to the Child. What's my point? Glad you asked. If I wanted to create a class that maintains various user lists: class UserLists < ActiveRecord::Base has_many :naughty, :class => "User" has_many :nice, :class => "User" has_many :absent, :class => "User" end I would expect some fact tables to be created: naughty_users (with columns id, userlist_id, user_id), nice_users (with id, userlist_id, user_id), and absent_users (again with id, userlist, and id). - Could someone set my thinking straight here?

[Rails] Re: Keeping separate lists of parent objects
I think I've figured it out. Sorry for posting what amounts to an architectural question here, I'm guessing that's not really what this board is for. For anyone curious about what I decided to do: I haven't totally decided yet. I might trash the idea of a "Verification" class, and instead opt for a Vote class: Vote: type user Then it would be a polymorphic association like this: class Vote < ActiveRecord::Base belongs_to :voteable, :polymorphic => true end class Post < ActiveRecord::Base has_many :votes, :as => :voteable end class Product < ActiveRecord::Base has_many :votes, :as => :voteable end Otherwise if I stick with my verification class, I think I'll need to do some sort of HMABT relationship, and I honestly don't see the point. So yeah. I'll probably just do the Vote thing. Cheers! On Jan 27, 12:55 am, Steve H wrote: > OK here's the deal.

[Rails] Extending AR to write audit columns
Rails 2.2.2
Ruby 1.8.5
I am attempting to extend AR with a generalized audit attribute setter.
I have written this code, which does not work for reasons unknown to me.
Perhaps someone here can explain why it does not.
# Put this in config/initializer as active_record_addins.rb
module ActiveRecord
module HLLAuditStamps
def self.included(base)
super
# alias_method_chain :create,:audit
# is the same as:
# alias_method:create_without_audit, :create
# alias_method:create,:create_with_audit
base.alias_method_chain :create,:audit
base.alias_method_chain :update,:audit
end
private
def create_with_audit
write_audit_fields
# Now we call our alias to the original method
create_without_audit
end
def normal_time_now
if base.class.default_timezone == :utc
return DateTime.now.utc
else
return DateTime.now
end
end
def update_with_audit
write_audit_fields
update_without_audit
end
def write_audit_fields
write_attribute('accessed_at', normal_time_now) if \
respond_to?('accessed_at')
write_attribute('accessed_on', normal_time_now) if \
respond_to?('accessed_on')
end
end
end
What I intend is that whenever the AR create or update method is called
then the attributes specified in write_audit_fields are set to the value
provided by normal_time_now. They are not and I cannot tell why.
Any suggestions as to what I am doing wrong?

[Rails] Multi table inheritance problem with has_one relationship
Here is my issue class TransactionProduct < ActiveRecord::Base has_one :product, :class_name => 'Product' end class Product < ActiveRecord::Base set_inheritance_column :class_name end class ProductVT < Product def self.base_class ProductVt end end So when I do Product.find(:first) I got an instance of ProductVT with only the columns of Product, which is ok. Then when I do reload like this : Product.find(:first).reload I do have a complete instance of ProductVT. But When I do nagivate on Product from TransactionProduct and I do reload on the instance of ProductVT it does not reload the ProductVT, it does it on Product TransactionProduct.find(:first).product.relaod (reload the product instance instead of ProductVT) Even if I see in the console that is a ProductVT it reloads Product. I checked in development.log and in performs the query on Product. Any idea.

[Rails] Re: Is there a "touch" method for associated records?
Thanks, Denis. The project in question is actually a periodic email pull for marketing purposes, which is why I'm taking pains to model a "one email per user" expectation, something that current project does not have. (I'll work them into an actual login/password protected profile later...) The reason that the updated_at is important is the nature of the marketing message, which will be one of those "Since you visited the site 2 days ago" sorts of things. If a user registered for the first time (and created a User object) 3 days ago, but then came back in today, registered again (and thus linked to but did not create a User object), I would not want to send that message to that person. So I need some way to touch the User object at each registration. I think the option to create a different dedicated field on User, like maybe last_registered_at, works best - it clearly defines the meaning of the field for the next developer who comes along.

[Rails] Re: How to pass current value of form field in link_to?
Where is the value in the text field coming from? If it's coming from your app (e.g. from the database or from a user passing parameters), then you can do this on the Rails side of things, and it seems most likely that you want to set an instance variable in the controller (e.g. @text_field_value = [value]), which you can then use in both your link_to and text_field. If you want the text field to dynamically update as the value of the text field is changed, then you should use Javascript, such as something along these lines: Default text Best of luck, Greg On Jan 27, 12:54 pm, Joe Peck wrote: > FWIW, I'm opening "preview" in another window. > > For right now, I plan on passing the current value of the text_field by > setting params[:body] equal to it, but that doesn't seem to be the best > idea.

You should look into AR Mailer: http://seattlerb.rubyforge.org/ar_mailer/ The basic idea is that rather than actually sending emails, your app saves emails to the database.

hi
I have an RSS feed on my page and if the rss source is not aviable it
prints out an error.

How can I tell ruby only to use the rss feed if the rss source is
aviable?
something like unless? or so?

[Rails] Re: Is there a "touch" method for associated records?
I can see why you'd want to do this, but I'd leave User.updated_at alone and track this 'dirtiness' in some other way. There's no reason you can't do it, but as you say you'd have to accomplish it with an AR callback on Registration, not User. The default way automatic timestamping is implemented in AR implies that the semantics of the updated_at timestamp are when the object *itself* was updated. If you change this behavior, you run some risk of a future developer (or yourself in the future) not realizing that updated_at *also* means the user's registrations had changed. (As you said: "but User isn't technically changing".) You also then lose the ability to know when the User object itself was changed, as opposed to the list of registrations (but maybe you don't need to be able to make that differentiation). If I were convinced I needed to do it this way, I would probably add a method User#registrations_changed and have the Registration callback call that, so that this behavior is explicit (and, as you desired, visible in the User class). And would this be better on after_save, not before_save? And what events in the association would update the user? Adds, deletes, modifies? My approach on this would also depend on why I needed to have the user's update date be updated like this; how are you going to use that fact, and could it be done by coming into the association via registrations? E.g. "show me the users whose registrations changed yesterday" could still, I think, be done fairly efficiently even without what you're proposing. dwh Duane Morin wrote: > I'm sure I can whip something up to do this, but I'm wondering an > elegant solution already exists.

[Rails] Is there a "touch" method for associated records?
I'm sure I can whip something up to do this, but I'm wondering an elegant solution already exists. I will have any number of Registration objects coming in through web form, but I wish there to be only one User object per unique email address. So far this works fine. So Registration belongs_to User, User has_many Registrations. (This, by the way, is because the site does not have a persistent profile/logged in session and thus the same person could fill out the registration form multiple times.) What I'd like is if a person comes in a second time, creates a Registration object using an email address that already has an associated User, then update the User.updated_at field. In other words, the clean/dirty status of User is based on the most recent Registration object that was added. Does such a feature already exist in the association? I figure I could get around it altogether by defining User.updated_at as the max of registrations.updated_at, but that's pretty inefficient. My other option is just to put in some sort of before_save filter on Registration. But it seems better placed on User - but User isn't technically changing during this operation, right?

On second thought this might be a better approach:
class Project < ActiveRecord::Base
before_destroy :protect_no_project
private
def protect_no_project
!name.eql?("No project")
end
end
It sounds like overriding the callback directly may not be the best
approach.

[Rails] Migration Broken??
I've created a migration to create a new table. I'm noting that the format of the migration name created by the generator has changed. Up until now, the migration names were of the form "00n_" ... now the form is _. The problem that I'm having is that rake db:migrate is trying to rerun all my migrations from "001" forward. the schema tables in the database show the schema to be at 19. I would have expected the new migration to be 020_, but the name format has changed as shown above. Obviously, something has changed in this area. I've tried googling, but I haven't found the right search terms. How do I get migrations to run again. I'd be happy to reset everything to the current state of the database, then move forward with the new migration. I'd be happy just to get it working again. Can anyone offer any help -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] manipulating "params[:some]" with ActiveRecod::Find on ":select" method
Hello all,
I trying to pass the params from a form to the :select (field list) in
my controller
like this => Processo.find :all,:conditions => {
:tipo_acao_id =>
params[:tipo_acao_id],
:fase_id =>
(params[:fase_id]),
:resultado_id =>
(params[:resultado_id]),
:situacao_id =>
(params[:situacao_id]),
:justica_id =>
(params[:justica_id])
}, :select =>
params[:some]
So, the SQL returns an error, the fields are going together w/o spaces
or comma!
How to convert the params[:some] into a formatted string to make sql
works:?:
tnks a lot!!!

Wouldn't this make all records of the table read only? I don't think
that's what the OP wanted.
I'd say use the the before_destroy callback to validate the deletion:
def before_destroy
!project_name.eql?("No project")
end

That means that what you pasted: development: adapter: mysql database: web host: localhost username: root password: is very different from development: adapter: mysql database: web host: localhost username: root password: Also have all three environments set to use the same database is a very bad thing (unless you want all of them to get wiped everytime you run the unit tests).

[Rails] format.atom w Rails 2.2
in Rails 2.1, this works.. but I am stuck w Rails 2.2
class PostsController < ApplicationController
def show
..
respond_to do |format|
format.html
format.atom { render :action => 'changes', :layout =>
false, :content_type => 'application/atom+xml' }
end
end
def changes
respond_to do |format|
format.xml { render :layout => false, :content_type =>

I have a view, changes.xml.builder, building the xml code, but I got
a missing template as an error, when executing
http://localhost:3000/posts/show/5
ActionView::MissingTemplate (Missing template posts/changes.erb in
view path .../Projects/franchising/app/views:):
If I set a changes.erb, the xml code is sent...
