[Rails] Nested form with a N-N relation and a predefined list of elements to choose
Hi, I recently had to deal with nested form, and I found quite complex to handle it with my situation. I have a list of choices and want to allow the user to use some from a predefined list, by using checkboxes. I posted the question on Stack Overflow a few days ago, but nobody answered yet. So, to not duplicate the text, here is the link: http://stackoverflow.com/questions/3622312/how-to-write-properly-a-nested-form-with-a-n-n-relation Regards, B.D. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Re: [Rails] Pass selected value in combo as a parameter

Hi,
I have a select in my form:
%= select @issue_type, name, @issue_types.collect {|p| [p.name,
p.id]} %
What I need to do is execute a method passing the value selected in the
combo. I've tried lot of things, but I couldn't.
Where are you trying to execute the method? In the browser or in the
server? If in the browser then you will have to use javascript (in
which case it is not really a Rails question), if in the server then
put the select in a form and the selected value will be passed in
params when the form is submitted.

[Rails] Trying to create a collection to use for a report
I have a database of people that have used a local foodbank. The
problem I'm having now is that i need a way to put 2 collections into
one variable, like rails does it for partials. I want a variable
@oxford that does a Household.find_all_by_zip('01540'). This is no
problem.
The trouble comes when I try to combine lists of new families and
returning families to feed the partials properly.. What I have is a
main page
monthly.erb
oxford families
render partial = 'monthly_report', :collection = @oxford
_monthly_report.erb
new families
render partial = 'monthly_graph, :collection = monthly_report.new
returning families
render partial = 'monthly_graph, :collection =
monthly_report.returning
Rails doesn't seem to like these two areas in the monthly_report
variable without being setup, so I hope there is a way to do this. I'm
hoping there is a way to set your collections the way you want to do a
report. Please help me with the proper way to set this variable up

This has nothing to do with my question, though, as it doesn't involve MySQL in any way. Now, if someone *does* know about MySQL's specific behaviour and take it for standard, they might be tempted to base a solution on that.

[Rails] Re: Using ActiveRecord Find with associations
As I am sure you know the 'find_by*' methods are all dynamic. They are based on the field/column name, not on the type of object the column is supposed to reference (if any). AR will do the magic of finding the ID value if you pass an object to the method but apparently it will not be magic enough to let you remove the '_id' suffix from the field/column name in your 'find_by*' method name. It would be nice if the Rails guys made a little change so we could do what you wanted to do here, though. ;) On Sep 3, 8:27 pm, Pito Salas li...@ruby-forum.com wrote: Here's an example: class LineItem ActiveRecord::Base belongs_to :order end class Order ActiveRecord::Base has_many :line_items end my_line_item = LineItem.find(:zipcode = 12345) Order.find_by_line_item(my_line_item) # doesn't work Order.find_by_line_item_id (my_line_item) # does work I was surprised by this, because it seems to force me to make reference to the id field of the line item, rather than referring to the LineItem as a class or type in the Order.findxxx statement.

I think one of the things you might need is a 'timer', which will let your code 'sleep' before calling again your 'how_finished' function. I have never done this but remember reading about it, I googled for 'javascript sleep timer' and one of the links I found was this: http://www.daniweb.com/forums/thread47199.html In order to communicate with the server from Javascript I would look into Prototype or jQuery.

[Rails] Dynamic Filters with AJAX (like Redmine/Trac)
Hello Guys, I have a model Person with lots of columns (date, int, string, so on) and right now I need to make a filter for my costumer. My goal is something like this: http://www.redmine.org/projects/redmine/issues. Or, even better: http://trac.edgewall.org/demo-0.12/query. The most interesting feature for me is to be able to choose different columns and to have customized options (LIKE or NOT LIKE for strings, BETWEEN .. and .. for dates, and so on) Unfortunately, Redmine only allows 1 criteria per database column. Trac, on the other hand, accepts OR and AND, so I can make complexes searches, like: something AND something AND something OR something else AND something else That said, my questions are: - Does anybody know anything (Gem, plugin or tutorial) that can help me on the backend or on the frontend? I am using jQuery and Rails 3. - Is the new ActiveRecord Query API on Rails 3 complete enough to make this in a DRY way or should I use a specific Gem for searching (eg. searchlogic)? - Is there any opensource Rails project with such a complete filter like Trac? - Should I try to release it as a Gem when its done? :D Thanks in advance and please excuse my poor English :P -- Fernando Brito -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Please help up make a desition, rails 2 or ralis 3, which is better for a new project in real life? -- James H. It all depends on what the app is going to do/use.. You are definitely right thinking you will have faster more stable success using rails2. That is not a rails thing but anyone in technology long enough knows this tradeoff no matter the platform. (java, .net, python, drupal, etc..) The bigger slow downs/bugs/time lags tend to be around the plugins/ gems. It takes time to get those all working properly. Everyone wants to be on the newest version but think about servers also. If you keep upgrading your servers a lot of software will break. You can't go install redhat 6 as soon as it is released and think your not going to run into issues. Also think about how many bug fixes and service packs come out after new things arrive. You need to be careful in your decision. What I have learned in all my experience is don't be bleeding edge unless you got it like that and/or want it like that. It seldom is the 'logically smarter' choice for the majority of scenarios. +1 One thing that might change this thinking (for me anyway) is the launch date for the project. If it's in a month or two, I'd stick with 2.x because I don't have the time to deal with plugin/gem issues. If it's 6 months or a year from now, I'd be much more likely to deal with those issues because come launch time 3.x will have had all those things worked out. A timeline of that duration would also give me the time (or let me plan for it) to *help* fix those plugin/gem issues and contribute back. -philip I'm going to tell you to go with Rails3 and Ruby1.9.2 and explain my opinion. Rails3 went beta the first week of February 2010. I was just starting a project with a new client and we figured that going with Rails3.beta was the way to go because it would be final before the project was delivered. At that time, we were wrong. After less than a week, we retreated to 2.3.5 because there were so many little problems with rails and with bundler (and actually more with bundler than rails). (We were using ruby1.8.7) That was 6 months ago. In July 2010, another client started a project. Rails was now 3.0.0.beta4 and starting was much smoother. There were still places where changes from 2.x and documentation that was playing a bit of catch-up to the code gave us fits, but those were manageable. Have there been problems? Yes, but relatively minor (although we did submit a patch for a bug in ruby's CSV standard library). Rails3 forced a decision between ruby-1.8.7 and ruby-1.9.2-something (because it wasn't stable with 1.9.1) and we were at 1.9.2-r23238 (yes, a particular revision in ruby's SVN repository). Now we have an official Rails-3.0.0 release, Ruby-1.9.2-p0 release and gems that are quickly catching up. Seriously, the biggest issue with gems has simply been deprecation warnings -- they have worked fine. There are *significant* differences in ActiveRecord between 2.x and 3.0 and routing has been completely overhauled, too. If you don't already have Rails2 projects, then you'll have to learn how Rails2 does things and then have to re-learn how Rails3 does the same things (because you *will* want to upgrade). The documentation will catch up. The Rails guides are good and there has been over 6 months of beta/rc time for a lot of issues to be baked out of the final release. Any gem maintainers who may have been waiting for an official release no longer has to wait to put the final polish on their gems to make them ready for ruby-1.9.2 or to work seamlessly with rails-3.0.0. Anyone starting a new project right now should definitely be using Rails-3 and Ruby-1.9.2 (or perhaps 1.8.7 if you're limited by your hosting environment, but if you don't have either 1.8.7 or 1.9.2 available then you maybe you need to find a new hosting provider). -Rob Rob Biedenharn r...@agileconsultingllc.com http://AgileConsultingLLC.com/ r...@gaslightsoftware.com http://GaslightSoftware.com/ -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] CSRF protection not working with jquery ajax post request
Hallo,
I want to test the csrf protection of my application but forgery
protection is not working with jquery ajax request.
I have used Unobtrusive Javascript with jquery
I have removed the
%= csrf_meta_tag %
so that my application do not include authenticity token.
In my view I have the following code
$(function () {
$('#alert').click(function () {
$.ajax({
type: POST,
data: ({ lo: 67, pi: 22 }),
url: '/test/set',
});
})
});
I have also include in the application controller
protect_from_forgery
and have set in development configuration
config.action_controller.consider_all_requests_local = false
However the post command is completed successfully.
Does anyone know why the protection is not working?
Thank you

[Rails] Re: Store a single variable / row in database
IMHO The biggest problem with rails is the fact that it makes working easy and fun as long as your work can follow the MVC system. If you try to do it your way it won't be the rails way (at least as far as I know). If you want to track any more information other then number of pages views, create a page_view model and give it some logic to do the rest of your magic. If you want to track views of a specific model, add a page_views field to that model. If you just want to track the number of page views on your entire website use an analytics program :) Brian On Sep 4, 1:26 pm, Shea Barton li...@ruby-forum.com wrote: What would be the best way in rails to store a single variable and have it persist.

I may be wrong but have you got a validates_uniqueness_of on ident?
That query could be checking to see if there is already a matching
ident. The id3 could be so that it does not find the one you are

I use BigDecimal, but it craps out of the input number is something like 14,53, Rails transforms it as 14.0 Any solution? Are you really using the comma in the data? This IRB session suggests what might be happening (unless there's a en ENV flag that allows the comma?): require 'bigdecimal' = true x = BigDecimal = BigDecimal x = 14.4564 = 14.4564 x = 14,4564 = [14, 4564] -- 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: Cannot seem to display Comments on User Show Page
I figured out the problem with the original post, but I have a new problem. When a user submits an invalid comment(if the title or content does not validate correctly), they get sent back to the article. There are two problems, though. 1. The form does not keep the previous field content, so the form resets. 2. All the comments disappear. Articles controller: def show @article = Article.find(params[:id]) @comments = @article.comments.paginate(:page = params[:page]) @title = @article.title end Comments controller: def create @article = Article.find(params[:article_id]) @comment = @article.comments.build(params[:comment]) @comment.user_id = current_user.id if @comment.save flash[:success] = Comment saved. redirect_to @article else flash[:error] = Error in creating comment. render 'articles/show' end end Here's the comment form and the comment display code, if you need it: Comment Form: %= form_for([...@article, @article.comments.build]) do |f| % %= render 'shared/error_messages', :object = f.object % div class=field %= f.label :title %br / %= f.text_field :title % /div div class=field %= f.label :content %br / %= f.text_area :content % /div div class=actions %= f.submit Post Comment % /div % end % shared/_comments.html.erb: % unless @comments.nil? || @comments.empty? % %= render :partial = 'shared/comment', :collection = @comments % %= will_paginate @comments % % end % shared/_comment.html.erb %= comment.title %br / %= comment.content %br / %= comment.user.name %br /br / Thank you. -- 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: Store a single variable / row in database
What would be the best way in rails to store a single variable and have it persist. Like a have a variable that says total_visits that counts the total number of page loads. The only solution I can think of is having a table with a single row. One answer would be yes, pretty much if you really want to store a single data point that's accessible to a number of instances of Rails, then either a file or a database is what you'll need to use (assuming you don't trust anything RAM based). However, your specific scenario could quickly become an extreme bottleneck. It would be better served by logging (preferably asynchronously), and then read tally the log to create your total. Do it periodically, so you're not starting from the first log every every time. There's probably other ways, but using a single var for something like page loads is looking for trouble as your app scales. If you know the page requests will be low enough to not be a bottleneck then using the DB with row or table locking (effectively the same for this case) might be OK. Another option if you can tolerate the potential for a little inaccuracy is to go ahead and use RAM (with a mutex) to keep the count, and periodically write that value to disk to minimize the disk access. If you have load balanced app servers you'll need a central RAM cache like memcache. That's what comes to my mind -- others may have better ideas. -- gw -- 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: Store a single variable / row in database
Well, specifically what it would be for is an app which parses / collects stats on twitter. I want to have a persistant of the ID (twitter side) of the most recent parsed tweet, so I know where to start at the next startup, or in case it gets interrupted. I don't what to log every tweet I parse to the database (there are tens of thousands), nor do I need to. So a single-row table would be the best way to do this? -- 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] Rails friendly Forex broker?
I'm starting a new hobby. Going to learn about and have a try at building some automated trading systems for forex and other markets. So far I've been very disappointed with the results of my googling looking for a broker and/or third-party product to use as a bridge between the software I will build and an actual trading account. Since I already know a bit about Rails, I'm thinking I would like to start there even if it isn't the most obvious platform from which to do this sort of thing. It does, however, provide a familiar set of tools I expect to use such as Ruby and mySQL front end. At the same time, once it gets to that point it can make it easy to create an administrative control panel for my trading activities that would be accessible from anywhere (with a strong password ;) ) Thanks for any hints you can give me on where to find an easy access point to this world from Rails. jp -- 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] Developing a web chat using Rails 3
Hi! I'm trying to develop a web chat (like the facebook one, but much simpler) that works inside Rails 3, and so I'm inquiring about the methods used for this scope. I had some success applying this guide http://www.web2media.net/laktek/2010/02/16/building-real-time-web-apps-with-rails3/ , so now I am able to send messages form the server to the client. Anyway, I read about some sort of XML-based protocol called XMPP, which seems to be widley used in this cases. I really don't know anything about either cramp or XMPP, and so I would ask: * Do you have some info about cramp (guides, explanations, examples...)? apart from the above post, I found this http://m.onkey.org/2010/1/7/introducing-cramp , and nothing else (maybe because it is relatively young?) Above all.. * ... how does cramp work? Is a parallel server? A thread? What is it??? :) * Is XMPP the way? Do you know how to implement it? * Do you know anything about the argument?
