I figure that I'll start with an array of size 3,000. Then I would probably want to iterate over it, possibly saving the result of the operation of each row to a new array but this area is a little foggy. Any suggestions? Assuming you want to calculate something like percent change for each day, you could load the entire result set into an array, and then do something like: changes = @stock_data.each_with_object([]) do |data, array| last_value = array.last.value change = (data.value - last_value) / last_value * 100 unless last_value.zero? array [data.transaction_date, change] end -- 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] Re: I need a lot of advice here - let's start from the beginning
For IDE, I would suggesst Aptana's RadRails (http://www.aptana.com/ rails). It is based on Eclipse and designed well to implement/deploy RoR applications (it has a nice feature called AptanaCloud which lets you deploy RoR applications in the cloud in minutes). One thing to remember, building RoR applications is just one part of the equation, with the other being deployment. There are several solutions around for this (mongrels+rails, apache+phusion-passenger+rails, etc.) and they all require certain level of Linux expertise. That is what makes an IDE like RadRails sweet: it will take care of the deployment part for you so you can focus on building the application and not have to configure a Linux Box with server capabilities.

Hi all,
I am seeing a behavior for which I can't find documentation. I am
posting a form to a url with query params formatted in the Rails manner:
/controller/action?foo[bar]=3 # Of course, the brackets are properly
encoded
When doing this, the actual form fields get lost, e.g.
params[:foo] # This gives {:bar = 3}
even though the form has other fields for foo.
Any ideas?

so params[:foo] is being populated partially from parameters in the

to see if this is a regression.

[Rails] Is there a rails equivalent of body onload=do_stuff()
Hi,
I want to call a javascript function after my page has loaded.
Currently I am using:
body onload=do_stuff()
Is there a neater / tidier way to do this using any rails specific
commands?
I found this:
document.observe('dom:loaded', function() {
$('state_field').hide();
$('person_country_id').observe('change', countrySelected);
});
which is part of a tutorial for creating dynamic drop down menus, but
when I, for example, try:
document.observe('dom:loaded', function() {
alert('hello');
});
this has no effect, rather it is output as html, as though I had witten
pdocument.observe('dom:loaded', function() {alert('hello');});/p
Grateful for any help.

[Rails] Generating and authenticating by API keys
I'm trying to get my head round offering up an API for a RESTful app; is it just a matter of; 1. adding an api_key column to the resource on which incoming requests will made (the app has a User model but I think the API authentication will need to be done on the Site model to which Users belong), 2. generating the API key using Digest::SHA1 or similar (the last dev used SHA1 for the passwords), 3. authenticating via API keys in a filter (perhaps something along the lines of option 2 here http://www.whatcodecraves.com/articles/2008/11/25/how_to_make_an_api_for_a_rails_app/). Unfortunately, the authentication lib is custom (I would much prefer to be working with one of the community adopted plugins such as Authlogic, which appears to have API key authentication anyway).

[Rails] Ruby and RoR Setup Frustrations
Okay, I'm starting to get a headache (mostly because I refuse to give up) and continue to try to get ruby and ruby on rails configured. Let me explain my issues... I'm running Windows Vista with Ruby 1.9.1 and MySql 5.0.x It took me awhile to get this setup to work but I managed to do it. In order to get Ruby 1.9.1 to work I had to use a ming compiled version. In order to get mysql to work, I had to build the binary locally. The good news is I can create a new rails project, start it, and the about your rails environment shows the following: Ruby version 1.9.1 (i386-mingw32) RubyGems version 1.3.3 Rack version 1.0 bundled Rails version 2.3.2 Active Record version 2.3.2 Action Pack version 2.3.2 Active Resource version 2.3.2 Action Mailer version 2.3.2 Active Support version 2.3.2 Application root D:/ncaastatpages Environment development Database adapter mysql Database schema version 0 So, it sees mysql, everything is golden and throws no errors. That's the good part. Now the headache begins. Issue 1: Because of the way I had to compile mysql to work and using ruby -e to require it, there's no gem listed. If I require 'mysql' everything works just like a gem is installed. However if I do gem list it does not show up. While this is just a trivial issue (for me), it's a bigger issue with some IDEs like Aptana Studio which tried to install a different mysql gem and screw up my entire setup. Issue 2: Here are the gems I have currently (that work 100%): All Rails Gems (2.3.2) --action..etc.. capistrano (2.5.5) cgi_multipart_eof_fix (2.5.0) gem_plugin (0.2.3) highline (1.5.1) net-scp (1.0.2) net-sftp (2.0.2) net-ssh (2.0.11) net-ssh-gateway (1.0.1) rails (2.3.2) rake (0.8.7) rspec (1.2.6) rubygems-update (1.3.3) test-unit (2.0.2) Notice that mysql does not show up under the list but it's there because I used: ruby -e 'require mysql' With IDEs like Aptana Studio, they want to install mongrel, linefeed, etc. but they keep installing the wrong versions that require msvcrt-ruby18.dll instead of the msvcrt-ruby191.dll. So, my questions are in order: 1. What gems must I have working and operable to run a full rails development project? 2. Is there a way to tell Aptana Studio to not mess up my current rails installation by attempting to install gems that are outdated or the wrong kind? 3. Is there another IDE I should consider? (I tried Jedit but it felt clunky) - I previously used Scite which didn't give me any issues but again, it lacked a lot of features that I might need. 4. What am I missing here? My frustrations with Ruby and RoR isn't the programming! It's the installation! The programming, MVC concepts are wonderful! I've never experienced (working with any programming language) where the installation would be a 9 out of a 10 difficulty rating and the programming would be a 2 out of 10 difficulty rating for ease of use. I run a windows box and a virtual box with linux but I refuse to give up on the windows end. I want to be able to program with both systems. I'm not afraid to test the waters and go through hoops and hurdles to get them both working 100%. My issues are that the hoops seem to be surrounded by fire where windows is concerned.

[Rails] Re: Would ROR be a good choice to build my site?
Jack Jackson wrote: Would ROR be a good choice to build my site? Hi Gang, I'm in the process of developing a social media-ish site built around WordPress and VBulletin forum. A site where a visitor has a username and password and their own page on the site where various site interactions take place. I need a CMS framework to tie them all together along with other features like multimedia, video uploading/severing/, news/articles/information as well as user/visitor created content ala/ wiki's. I'll need a user-friendly backend to control the functionality. (aside from Wordpress and VBulletin's existing backends) Would ROR be suited for this sort of development? I'm going to be hiring a developer very soon and would like to have some honest opinions from those that know the platforms best. My current direction has me leaning toward Joomla or Drupal but I've heard so much about ROR lately, I want to find out more about it and if it's the best choice for my project. I hope to hear some good opinions. Thanks. I'm new here, especially with rails - but understanding the MVC concepts I would distinctly say no. A CMS system tied around Vbulletin will not work with rails because vbulletin was never designed with MVC in mind. It would not mesh well with rails mainly because of the following: 1) It's PHP and not MVC driven. 2) It utilizes hooks and plugins to modify code areas to your site (which would not be rails compatible). You are better off going with a completely new rails project environment from scratch or if you must use vbulletin then go with a vbulletin based CMS like VBadvanced.. -- 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] Re: Ruby and RoR Setup Frustrations
Pre-packaged version? JRuby is just a pure ruby interpreter writen in Java that is faster than the current 1.8 branch and is almost as fast as 1.9. And IDEs shoudn't really care about which Ruby version you're using, at least NetBeans and RubyMine don't, maybe it's time for you to change your tools. JRuby also has a compatibility mode to run as if it was a Ruby 1.9 interpreter, you should research and use it before making your mind. - Maurício Linhares http://alinhavado.wordpress.com/ (pt-br) | http://blog.codevader.com/ (en) On Sat, May 30, 2009 at 9:40 AM, J.

JRuby also has a compatibility mode to run as if it was a Ruby 1.9 interpreter, you should research and use it before making your mind. I will download and test Jruby to see how it functions firsthand. I'm not overly worried about deploying to a 1.9 environment right this minute. I just want to work with 1.9 locally, develop my apps locally, view them and test them locally. Once I feel comfortable with all of that (perhaps a few months down the road) I'll worry about the deployment phase then. Programming in the latest environment is critical to my way of thinking. I learn the latest and am not backtracking and having to adjust. Because I'm new to rails, in my opinion it is better to start with the latest version. When you say not supported you really mean not supported by some gem developers. 1.9.1 works fine on both windows and linux. Some gems though, do not. I've spoken with Luis about this and he's given me a lot of information as to why gems are not working properly, and I understand the frustrations firsthand. I'm really not here to argue or create issues at all. I'm generally a very helpful person, love assisting others, and am the type that will give to the community more than I take. However, I'm still learning the ropes so if you see any teeth in my comments (they are not meant for you). It is simply me dealing with the many frustrations of trying to get up and running. Again, I still need the other questions answered. If someone has answers to those questions, I would greatly appreciate it. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Mauricio, Thanks for the input with netbeans. I actually installed netbeans and tried to configure with jruby but had a lot of issues with trying to get jruby to work well with a test project. However, when I used netbeans with my current 1.9.1 and created a test project, rake created the DB, and then ran it through netbeans, it worked 100%. I like the feel of netbeans so I must thank you for giving me that heads up. I'll try to go back to jruby at a later date when I can understand it a bit more but netbeans is working well with my current source and because I installed it, I realized I needed warbler (so downloaded that gem).

Is this because a form submission REQUIRES the server to follow with a new page?

[Rails] Need help : How to render HTML inside of a JSON request
We have an app that is in production with Rails 2.1.2 and I'm about to upgrade to 2.3.2. However, I am having a problem with a number of AJAX calls and I could really use some help. The client will make an AJAX call to receive a json response, and the response includes an html string as one member of the json data object. We render the html to a string (render_to_string). and return the object. However, in the 2.3.2 version, we are receiving an erorr that some of the partials called inside of the render can't be found. I've isolated it to the partials that aren't fully qualified names. For example, this appears to fail: render :partial = 'comments/partial_name' If I change it to : render :partial = 'comments/partial_name.html.erb' and it works. It appears as though the fact that the call is a JSON request from the client is causing the render engine not to search for .html and .html.erb in the path, thus they fail. Any ideas?

[Rails] Routing Error with Passenger for Images and stylesheets
Hi,
I updated my server with the latest Rails (2.3.2) and Passenger (2.2.2).
I also updated my Rails app to run under 2.3.2. It runs
fine locally under Mongrel.
The app is deployed into my own home directory under: (deployed via
Capistrano)
/users/me/public_html/myapp/current (which is a symlink to the
actual app)
and it's accessed by the url:
http://myserver.com/myapp
I was getting routing errors, where Passenger/Apache could not find the
default route. But I found a post saying Passenger
has an issue with routing, so I added the RailsBaseURI to the
environment.rb file:
config.action_controller.relative_url_root = /myapp
I found another post that said my apache config should be:
VirtualHost *:80
ServerName myserver.com
DocumentRoot /home/me/public_html/myapp/current/public
Directory /home/me/public_html/myapp/current/public
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
/Directory
RailsBaseURI /
/VirtualHost
I have not .htaccess file in the public folder.
I am now able to get to the app, but all references to stylesheets and
images are giving routing errors in the
production.log file:

[Rails] Re: Rails: concurrency question
Steve Hull wrote: BUT Rails is essentially single-threaded (only a single request processed at a time), so if I have only a single call to my singleton instance method per http request, then it should be impossible to get concurrency problems with it. Right? It's actually possible to write various kinds of concurrent code in Rails -- it really ALWAYS was possible to have some concurrency, but not concurrent request handling, and whatever concurrency you added you'd add yourself. But in more recent versions of Rails, even some concurrent request handling is supported. allow_concurrency!. And perhaps Passenger in certain modes as Roderick says, I'm not familiar with Passenger. But you're basically right about the 'ordinary' mode of Rails execution, that only a single request will be processed at a time. This is increasingly not the only option for Rails though. But, yeah, you're also right that if you had Rails executing in a mode that allowed concurrent request handling, you'd need to take care of making sure your singleton object itself is concurrent-access safe -- the singleton pattern will take care of _instantiation_ of the Singleton object being concurrency-safe, but can't take care of it's own internal logic. So you can either do that -- or you can note in comments that this thing isn't concurrency-safe, and shouldn't be used in a concurrent-request environment. -- 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] Re: query on Ruby array
Conrad Taylor wrote: An Array instance can respond to both count and size methods. If you use size the method with a counter cache column on the has_many side, you can cache the total. You can't possibly mean an Array, because an Array doesn't know anything about going to databases or cacheing. An Array is just a list of stuff. You might mean an ActiveRecord Association collection object, which behaves a lot like an array, but also has some 'magic' ActiveRecord behavior on it. The fact that, as far as I know, there's no actual class name for this AR association magic collection object, makes things rather confusing, I agree. I think it's just some proxy methods singleton-added to an Array, leaving us without a good name to call what it is, making things confusing. Or if it really is a class, I don't know what it's called cause it's not mentioned in the docs. This is a kind of a-bit-too-clever ruby hacking that Rails, IMHO, uses sometimes when it doesn't really have to, making things somewhat more confusing than they need to be. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Sudhi Kulkarni wrote: Then in one of the periodic update methods if I access the session[:executing] it is not updated to done. Is there a problem if I try to update session variable in a different thread? Actually, this is precisely what I was trying to do in another thread here where Fred graciously helped me too. I'd advise NOT trying to use the session array Rails gives to you, but instead just telling the thread the sessionID, and ten doing all the session access yourself manually. That's what I'm doing. It's not TOO hard, although it inconveniently changes for Rails 2.2 vs. pre-Rails 2.2. See this: http://www.ruby-forum.com/topic/184782 And see if it makes any sense to you, or still seems worth it to you when you see what you must do. :) But it does seem to be working for me, with some basic unit tests. There's sadly one more added wrinkle with regard to race conditions when you start to deal with sessions like this, that can result in the main action over-writing the session data the thread tries to write, or vice-versa. I have a hacky way to minimize (although not totally eliminate that), that is Session-store agnostic. You can totally eliminate it if you're willing to hack the particular session store, as I believe Fred has also done for the AR store, but I think this is quickly getting beyond what you hoped would be an easy answer.

Jonathan Rochkind wrote: But it is do-able, although not easy, I don't think you can get away with just trying to access the session array itself in a thread that's out of the request loop. I'd add it's do-able ONLY if you are using a server-side session store. NOT if you are using the cookie store that's the new Rails default. With the cookie store there's simply no possible way to write to the session outside the request loop. So if you want to write to a session in a thread, you'd have to wait() on the thread before returning from your action, which might defeat the purpose you were trying to use the thread for in the first place. Also, if you are planning on using ActiveRecord in this thread, you've got to make sure to do a few other things to ensure your AR calls are thread-safe. Things which change slightly in different Rails versions, as Rails community has changed it's consensus on what sorts of threading are 'supported' in what ways. And ALSO, even aside from AR, I learned the hard way that (at least if you're using the standard 1.8 MRI ruby interpreter), if you want to send a thread off and let it keep going outside the request-loop, you'd really better set it's priority to -1, or it's going to end up interfering with your response being returned even though you don't think it should. Contrary to popular belief, it IS possible to do concurrent programming like this in Rails, in all versions. But it's a big pain in the neck.

Sorry, this is a topic of interest to me that noone else is ever interested in talking about. PPS: REALLY, if you decide you want to set off a thread that will persist after the response is returned, despite the general pain in the neck of doing that cause neither ActiveRecord nor MRI 1.8 Ruby are entirely happy with it (but it's still possible if you take the right precautions)... AND... you need that thread to store state that later requests can access Consider just storing it in the db as an ActiveRecord rather than trying to put it in a session.

But you're on the right track. Note though that you've got to make sure all your logic (in this case in that hypothetical Singleton object), is concurrency-safe, if your rails app can possibly be deployed in any kind of a concurrent-request environment (or if you plan to create Threads yourself in your rails app, but hardly anyone ever does that). You could look at the newish Rails 2.2 ActiveRecord ConnectionPool for a model, since it's doing basically what you want, but specifically for db connections.

[Rails] Re: Need help : How to render HTML inside of a JSON request
RFine wrote: render :partial = 'comments/partial_name' If I change it to : render :partial = 'comments/partial_name.html.erb' and it works. It appears as though the fact that the call is a JSON request from the client is causing the render engine not to search for .html and .html.erb in the path, thus they fail. You got it. Why are you returning .html from a ajax/json request from the client, anyway? Generally, ajax requests from the client get back javascript (or specifically json), not html! Rails is trying to help you with this general case, because you can have the same action that will return partial.html.erb if it's an html request, or partial.js.erb if it's an AJAX request. I forget exactly how Rails determines when the format is js, but I know if you're using any of the Rails helper methods for ajax callbacks, they definitely include a query param to tell Rails what's what. So you can change the render call like you say. Or you COULD rename the partial in the old way partial_name.erb, so Rails will use it for any format request. But that's kind of weird (and now i'm not entirely sure it'll work). Or you could reconsider why you want to return HTML (rather than js/json) to a js request in the first place. Or you could take a look at respond_to to see how you can return different views for different request types. http://api.rubyonrails.org/classes/ActionController/MimeResponds/InstanceMethods.html#M000368 -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Personally, that's one reason I don't like making method calls without
parens, or doing anything else that relies on non-obvious
order-of-evaluation-binding just to save a couple of parens.
foo( bar {} )
or
foo( bar do
end )
will both do the same thing. Although the latter is kind of weird style,
if I need a multi-line block for bar, I'd personally just use a
temporary var instead.
result = bar do
end
foo(result)
But everyone's got their own style, I guess. Of course you COULD use
{||} with multi-lines too, but it would also be stylistically weird in
my opinion in that case.
foo bar {|a|
stuff
more stuff
}
That's just weird. And if I DID it, I'd still want to put parens in
around foo's argument, which would make it even weirder looking.

All I can say is that in the (non-Rails) project where I'm consistently using unobtrusive JS, this has not been my experience. It hasn't led to any more lines of code. This does in part depend on your HTML DOM being fairly well structured with good classes and id's. In my experience, once you learn how to do it right, it's no more lines of code to maintain, and forces you to have better-structured HTML to boot, which is an added advantage. But there is a bit of a learning curve, sure. Now, if you had to give up all the Rails helper methods (that are essentially dynamic js-code-generators), then THAT would lead to more code. I wouldn't want to do that. So I'm going to check out the UJS Rails plugin that Fred helpfully alerts us to. But to each her own. I was gonna try to look at your example to show you a short concise unobtrusive JS version that would do the same thing, but I don't understand the case quite well enough and don't feel like spending the time trying to just to make a point.

[Rails] how to transform data to database (translation - i18n)
Hi Everyone, I'm using I18n in my rails app and I'm very pleased about it. However, I'm now having problems posting Date objects to the database. The problem is that in my text field the date is represented in Dutch. So for example: I have a text field: %= f.calender_date_select: date_attended % Where I fill in a date like: 26 oktober 2009 Now the database won't recognize this, and that's probably because he's posting a foreign language to the database which he doesn't understand. I'm guessing I should translate each month somewhere (in the model??) like this: Januari = January Februari = Februari Maart = March etc.. etc.. Any suggestions??

I tried the recipe in the rails recipe book but the page takes a long
time just for the page to load due to the array being generated.
Also, you may also try using the :select to limit what fields you fetch from
your database. If you can provide a sample code, we can better assist you.
Other than that, I would recommend using the
#{RAILS_ROOT}/script/performance/benchmarker
to profile your queries to make sure that your optimizations are truly
working
for the query in question.
Good luck,

[Rails] Re: Need help : How to render HTML inside of a JSON request
Thanks, Jonathan. First off, I inherited this code base and I realize that there is a better solution... specifically to do a request with update. The request ask for json because they return both data elements which are used in the page and an html block as a replacement for a section. If there were only one call... I would just fix it by hand, but this approach has been used in multiple places in the code base. They make a call that constructs a json object, and one element in it is a string of html to replace a div. Unfortunately, when we call render_string -- now the render wont look for .html.erb objects. I've tried adding :content_type=:html to the render call, to no avail. I've also tried adding Mime::HTML and 'text/html' as :content_type parameters. I think I just need to temporarily override the request content type during rendering, but I can't figure out how. Russell On May 30, 11:16 am, Jonathan Rochkind rails-mailing-l...@andreas- s.net wrote: RFine wrote: render :partial = 'comments/partial_name' If I change it to : render :partial = 'comments/partial_name.html.erb' and it works. It appears as though the fact that the call is a JSON request from the client is causing the render engine not to search for .html and .html.erb in the path, thus they fail. You got it. Why are you returning .html from a ajax/json request from the client, anyway? Generally, ajax requests from the client get back javascript (or specifically json), not html! Rails is trying to help you with this general case, because you can have the same action that will return partial.html.erb if it's an html request, or partial.js.erb if it's an AJAX request. I forget exactly how Rails determines when the format is js, but I know if you're using any of the Rails helper methods for ajax callbacks, they definitely include a query param to tell Rails what's what. So you can change the render call like you say. Or you COULD rename the partial in the old way partial_name.erb, so Rails will use it for any format request. But that's kind of weird (and now i'm not entirely sure it'll work). Or you could reconsider why you want to return HTML (rather than js/json) to a js request in the first place. Or you could take a look at respond_to to see how you can return different views for different request types.http://api.rubyonrails.org/classes/ActionController/MimeResponds/Inst... -- Posted viahttp://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] instance variable (conrollerview) and RESTful
I'm a bit flummoxed by something and hoping someone can offer an explanation. If I create a controller (test) with a RESTfully named method and a view (.../test/index), the value of the instance variable passes to the view. class TestController ApplicationController def index @variable = 'Pass to a view' end end - If I rename the view to (.../test/foo) or some other non-RESTful name and appropriately alter the controller method, the value of the instance variable does not pass. class TestController ApplicationController def foo @variable = 'Pass to a view' end end --- A half dozen inprint and online books seem to dispute my personla experience and suggest that the name of the method and view should be irrelevant. So does anybody have a suggestion as to what is going on? Is my routes.rb file where I need to be looking?

You are absolutely wrong. Since inline JS, by its very nature, is much
harder to refactor, in many, many types of cases, inline JS will lead to
significantly more code than unobtrusive external JS.
I think we are talking about slightly different things. I am not
talking about defining functions inline. I'm talking about calling
them:
script type=text/javascriptcall_my_function(here, forthis)/script
You can claim whatever you want but you are not going to get rid of that
from the page by adding a single line to a .js file somewhere. Period.
The end.
No. Just iterate over the affected DOM elements and apply an
appropriate abstraction.
Sure, but that is not one line of code. You are trying to make a rule
with no exceptions and you are bound to failure because of that.
You said you were snobbish about JS as compared to real languages.
Well, guess what -- JS is a real language, and quite a powerful one
too,
This was a joke about snobbishness, and not really anything else. Sorry
I did not make that clear earlier...
real language. That means writing complete routines in one place, not
scattered bits of inline code. [...]
The routines are in one place, a .js file. The calls are, often enough,
made in an html file.
while keeping JS out of the HTML. I guarantee that both
your JS and your HTML will be the better for it.
Inlining CSS is truly pointless, but when I look at a page source and
see a mix of html, javascript, and embedded whatever, I honestly do
not, never have, never will, have some sort of absurd formatting related
freak-out (like: See how much tidier your html is now!! Grow up).
You sound like someone who insists there is only one place to place an
opening {, when in fact there are a number of acceptable styles and that
is all they are: styles.
You are not
talking about any improvement in functionality or performance, after
all.
Wrong again.
No, you are wrong again. If you want to tell me
script type=text/javascriptcall_my_function(here, forthis)/script
represents some kind of performance issue (considering call_my_function
is already cached), I will tell you are wrong again, because you are.
I would hate to consider a case where an author decided *not* to do
something because it required inline js.
Read my lips: *NOTHING* REQUIRES INLINE JS! Anything doable with inline
JS can also be done without it.
Possibly, although you don't make much of a case to support that. But
just because something *can* be done one way or another doesn't mean it
*has* to be, unless you have a good reason for it, and since you still
have not come up with one, I am satisfied that it doesn't exist.

Also, in this instance, how does the do evaluate |page|? and last: where in the rails API docs is the reference for the page object? *args means that you can pass it as many arguments as you want (and if you were writing such a function then args would be an array containing those options). That doesn't necessarily mean that the function will do something sensible if you pass it 23 arguments (to know that you need to read the docs for it) block is basically just the block you give the function (and the fact that it's there in the docs is probably a bit of an artefact of rdoc - you can pass a block to any method (again, no guarantees on what that method will do with it). The 'do' doesn't evaluate page, that's just you giving a name to the object that link_to_function yields to you (which is an instance of JavaScriptGenerator or something similar). You might find it easier to get a solid grounding in ruby first before starting to fiddle around with rails. Fred I'm sure someone well versed in ruby can explain this to me. Thankyou for any help. Even links to documentation that explains these ruby operators would help.

[Rails] Re: Rails collection_select syntax issue
Thank you Matt! This worked nicely.

You're probably better off using select_tag, together with
options_for_select here. collection_select appears to be giving you a
bit more magic than you want...
Example:
%= select_tag :county, options_for_select([Please select a
county..., ]+...@counties.map { |c| [c,c]}) %
(change the entries in the map call if @counties has objects rather
than strings - the first entry in the array is the label, and the
second is the value that will be sent)

I'm trying to display unique counties listed in my database in select
box for a property database. I've figured out how to do this, but now
I can't figure out how to access the selected value of the select.
This mainly has do with the way the HTML select name is outputted.
My form code, county is an attribute for my property model:
%= collection_select(:property, :county,
@Counties, :county, :county, {:prompt = true}) %
This outputs the HTML
select id=property_county name=property[county]option
value=Please select/option
option value=Pearl RiverPearl River/option
option value=MarionMarion/option
option value=StoneStone/option
option value=LamarLamar/option
option value=ForrestForrest/option
option value=JonesJones/option
option value=WashingtonWashington/option/select
It is the []'s in the select name property[county] that is giving me
fits. The other items in the search form use select_tag so the output
is simply min_price rather than property[min_price]. This is
causing a syntax error when I'm trying to put together my search
results array in my Property model:
def self.find_by_lcc(params)
where = []
unless params[:mls].blank?
where mls = :mls
end
unless params[:county].blank?
where county = :county
end
unless params[:min_acreage].blank?
where acreage = :min_acreage
end
unless params[:max_acreage].blank?
where acreage = :max_acreage
end
unless params[:min_price].blank?
where price = :min_price
end
unless params[:max_price].blank?
where price = :max_price
end
if where.empty?
[]
else
find(:all,
:conditions = [where.join( AND ), params],
:order = city, price desc)
end
Due to the county problem all the records are being listed rather than
just the properties within that county. The browser URL string I'm
getting is:
public/land?mls=property[county]
=Stonemin_acreage=0max_acreage=1600min_price=0max_price=160com
mit=Search
I have searched for answers on this for a couple of days and I'm sure
it's a simple syntax method I need to use in compiling my search
array.
Thanks for any help!

[Rails] Re: Problem with Custom Form Builder
Fre: That was a typo. In my actual implementation FormHelper is a module and it doesn't inherit the builtin FormHelper, but includes it. So there was no problem. The problem I was having is with the FormBuilder itself. I beleive there was other code files that were creating the problem. Once I create a new rails app from scratch, everything works fine. Thanks for all the feedback. -Satynos Frederick Cheung wrote: On May 31, 1:59�am, Saty Nos rails-mailing-l...@andreas-s.net wrote: I don't see where my class is being inherited from module.
