[Rails] Rails app supplying image to a static page?
Can anyone help point me in the right direction on doing the following? Say I have a Rails app that deals with photos at photo.website.com, and I also have a legacy site at www.website.com. What I would like to do is from a static html page on www.website.com have a random photo displayed from the photo app. So, if I put something like this in my static page: would it be possible when a user hits the static page to have it routed to an action that would pull a random photo and return it to the static page in the form of an image?

[Rails] Re: Wrong number of arguments?
You're going to have to isolate what line the error originates from on
your application by going through the Rails trace information,
otherwise we're all going to be here forever trying to figure out what
the problem is.

[Rails] Wrong number of arguments?
I'm going through a tutorial here and running into an error I'm not sure
how to fix..this is my first foire into sessions.
Trying to create a shopping cart for a store app. I'm getting this
error:
wrong number of arguments (1 for 0)
RAILS_ROOT: script/../config/..
Here is my cart_item.rb model:
class CartItem
attr_reader :product, :quantity
def initialize
@product = product
@quantity = 1
end
def increment_quantity
@quantity += 1
end
def title
@product.title
end
def price
@product.price * @quantity
end
end
And my cart.rb model:
class Cart
attr_reader :items
def initialize
@items = []
end
def add_product(product)
current_item = @items.find {|item| item.product == product}
if current_item
current_item.increment_quantity
else
@items << CartItem.new(product)
end
end
end
And my add_to_cart.rhtml view:
The shopping cart
<% for item in @cart.items %>
<%= cart_item.quantity %> × <%= h(item.title) %>
<% end %>
When I first tried clicking the add to cart function for a product I got
an error that method 'product' was undefined but then I did rake
db:sessions:clear and now I am getting this wrong number of arguments
error - any ideas?
Thanks!

[Rails] Joins, Joins, Joins! Or Not?
Good morning, I have a quick joins-related question: I have a a list of followings (User following another user's activity) which basically have these followed users' ids under 'followable_id'. now what I want to do and finally have is to take these followed users and check what activities they have. each activity has a .user_id. how would I do this? So Basically A User is following X other Users (polymorphic intermediate model... a User can also follow discussions etc). Each of those users has a set of activities. What I basically want in a 'speedy' way is to get all followed users' activities. I kinda have a problem with the polymorphism of the Follow model, as apparently I cannot put a has_many relationship into the user model which would allow me a condition (followable_type = "User"), class (User) and source (:followable)... I am kinda lost.. been wrangling with join conditions all night :-/ Any ideas / suggestions? Would be highly, highly appreciated...!

same thing :(
i found some info here:
http://dev.rubyonrails.org/ticket/11078
and the link they reference
http://prototypejs.org/learn/extensions...there is a bit at the bottom:
// this will error out in IE:
$('someElement').parentNode.hide()
// to make it cross-browser:
$($('someElement').parentNode).hide()
soi tried these ways:
$(this.parentNode.parentNode).toggleClassName('complete')
$($(this).parentNode.parentNode).toggleClassName('complete')
$($('make_step18').parentNode.parentNode).toggleClassName('complete')
make_step18 is the id of checkbox i was testing.
but they all produce the same weird result where they don't update until
i click a second time. first click always does nothing.

[Rails] Who can consult with me on scaling and architecture?
I'd love to pay someone who has serious scaling experience to talk with me about how to plan for scaling. I'm developing a network of applications in Rails that could see tens of millions of users. I'm in way over my head, so I'd like to talk to someone who's been through it before. I want to know: - how to architect applications to scale smoothly - how to manage the growth in hardware - whether it's a bad idea to go with Rails at all. I'm not really sure where to start looking though. Are there people or companies in the community who consult on these topics? And while we're on it, are there companies that offer part-time sysadmin services for Rails stacks? -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Try adding `this`:

oops spoke a little too soon. the highlighting works great on firefox 3
but for some reason it acts a little weird on IE7.
the first check box i click doesn't do anything but then if i click
another check box the first check box row gets highlighted.
any idea what could be causing the incompatibility with IE?

[Rails] Re: Gem version issue prevent server starting
Andreas, RAILS_GEM_VERSION should match the version number of your installed rails. i.e.: on my system, rails --version gives Rails 2.2.2 thus, RAILS_GEM_VERSION = '2.2.2' is correct. 1.3.1 is probably the version of gem you have installed rick On Dec 29, 11:13 am, kevin lee wrote: > Hi All, > > I backed up my rails project and then reinstall Windows due to OS crash. > Then I install the latest Ruby, RubyGem, and Rails and copy back the > rails project.

It does require maintenance: whenever a name changes you have to

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.

All I need to do for a new project is to add the gem dependency to the environment.rb file. The command to install a plugin wants to go out and download the plugin from the internet. Yes, obviously, if I don't have the gem installed I would still need an internet connection, but I don't have to do any coping or hacking around to copy a plugin from some obscure location in my local system. Example: config.gem "rubist-aasm", :lib => "aasm" This line added to my environment.rb file is all I need to do in a new project to use the aasm gem that I likely already have installed on my system. > And I think an unfortunate one.

Using gems is natural for Ruby developers and using gem dependencies in Rails is a more natural fit than plugins for sharing code. I think of them in a similar way as I think about "Frameworks" in my Cocoa development. I like that there is basically one way to share code between different applications when doing Mac development. Plugins, in my mind, are a different thing. A plugin architecture is a means of extending an application's capabilities and not simply a means of sharing code between different applications. So yes, maybe plugins do have a place in this context, but that is not generally how Rails plugins are used. I realize this is subjective, but I do prefer sharing code through gems rather than plugins. > I like gems for things like RSpec that I actually use on every > project. But I hope the day never comes when I have to install a > special-purpose gem for just one app because it doesn't exist as a > plugin. > Rspec is actually a really good example. It was a plugin and is now a gem. I prefer it as a gem because I might want to share it between multiple applications. I only have to maintain one repository of "framework" code. If I need a specific application to depend on a specific version of rSpec I simply tell it that in it's environment.rb file. config.gem "rspec-rails", :lib => "spec", :version => "1.1.11" Then I can see all my dependencies quickly and easily in a terminal: $ rake gems - [I] rubyist-aasm - [I] rspec-rails - [I] rspec = 1.1.11 - [ ] hoe >= 1.8.1 - [ ] rubyforge >= 1.0.1 - [I] rake = 0.8.3 I = Installed F = Frozen R = Framework (loaded before rails starts) And manage my application's environment with the various rake gems:xxx commands. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I tend to like this idea as well, and is probably what I would do. The
caching of the ancestry would seem to be the most efficient. However,
there is one change I would make. I would reverse the ancestry so it
would be ("bart|homer|abe"). Doing this would make string comparisons
more efficient because you are looking for "bart" so having "bart" at
the beginning of the string may slightly increase the string comparison
efficiency.

> eventually!
This, however, I don't agree with. You need the full ancestry to
whatever the "root" objects is. The idea is to make one comparison with
no joins. The only way to do that I can think of is to have all the
information available at the row level.
If you end up with a very deep hierarchy, which would result in very
long strings, you could consider hashing the strings. This way you would
have a consistent length string to compare.
Example MD5 Hash:
bart|homer|abe = a92b11363ef020716f1ce3104e0cb0d8 (32 chars)
bart|homer|abe|john|william|ted|sam|joeseph|adam|bart|bill|jack =
ff2f4ad181a029935b89a36c7cd1dfbe (32 chars)
Obviously in some cases your losing rather than gaining, but at least
the string is consistent in length no matter how long the input string
becomes.

There are several ways:
* A Problem has_many Scores, a Solver has_many Score, and A Score belongs_to
both a Problem and a Solver. Process one Problem at a time, or one Solver
at a time.
* SQL, e.g. select_rows('SELECT problem_id, solver_id, result FROM scores')
Returns an array of array of strings with the values in the order specified.
E.g. [['123', '345', '-'], # problem 123, solver 345, result '-'
['124', '1024', '123'], # problem 123, solver 1024, result '123'
...
Remember, all values are strings and may need to be converted to integers.
* Use will_paginate to retrieve results in clumps, e.g. 100 results at a time.
HTH,
Jeffrey

Hi All, I backed up my rails project and then reinstall Windows due to OS crash. Then I install the latest Ruby, RubyGem, and Rails and copy back the rails project. But now I cannot start the server (ruby script/server). It gives the following message: ./script/../config/boot.rb:26:Warning: Gem:SourceIndex#search support for String patterns is deprecated Cannot find gem for Rails ~>1.3.1.0: Install the missing gem with 'gem install -v=1.3.1 rails', or change environment.rb to define RAILS_GEM_VERSION with your desired location. I changed environment.rb's RAILS_GEM_VERSION to 1.3.1 but it does not have an effect. Then I tried to install the missing gem as listed above (I think it is already installed but I try it anyway) and got the error message: Could not find gem rails locally or in a depository.

I apparently did not get to any of the sections that you did, because what you describe below is news to me.

PostgreSQL is certainly the best choice for *any* project, not just big ones. (I gave up on mySQL about 2 years ago, and I've been a lot happier since.) For some reason, it doesn't get enough love in the open-source Web development community. Basically, anything mySQL can do, PostgreSQL can do better, and it's really the only open-source choice if you're doing anything spatial or using non- trivial stored procedures. (I've heard that PostgreSQL clusters less well than mySQL, but I've never worked with clustered DB servers in either case.) > and suggests not > using migrations at all but using raw SQL to create the tables, > because he recommends that you NOT treat the database like a dumb data > store (something the rest of the Rails community seems to do and be > okay with) and make good use of check constraints, triggers, > referential integrity and the like at both the database level AND the > application level.

If this is what Chak really wrote, I wonder if he actually understands migrations. As Kevin and others have said, if that's an accurate description of what he wrote, he apparently doesn't realize that migrations allow the use of raw SQL, and he would also appear to be unaware of the excellent plugins from RedHill Consulting ( http://www.redhillonrails.org/ ), which address these very issues by adding constraints, transactions, and referential integrity to Rails migration syntax.

I would think that 188 classes in a Rails app would be a design smell, not something to brag about. Surely in most cases, an app with that many classes should be segmented into several related apps, perhaps following some of the ideas at http://revolutiononrails.blogspot.com/2007/01/plugems-rails-as-first-class-citizens.html (note: I haven't tried these ideas, but they seem reasonable). > > Basically - I'm wondering if I should be following the advice in the > book from the get-go when I design my application, or if I should > follow the best practices of the Rails community and not worry about > the "enterprise" stuff until I need to (at which point it may or may > not be too late).

[Rails] Avoiding ActiveRecord loading for efficiency with lots of rows
Hello all, This is my first post to this group, so please let me know if there is any protocol I'm supposed to follow that I missed. Anyway, I've been developing a Rails application for handling the registration and score data of a math competition. There is an existing Java applet that we use that generates the score data with reference to problem_id, solver_id, and the result (which is - if blank, 0 if wrong, 1 if right, and =n if n points of partial credit are to be awarded). It saves each individual's answer to each question as a separate row in the scores table. I've wrote a script to process this data in Rails. However, in 2008 there were over 15,000 rows in the scores table, and my current code loads every one of them. My current load time is about 5 seconds, and I think it's due to making an ActiveRecord object for every one. Is there a way to bypass making a separate object for each? I do need access to the data, but it would be nicest as an array or something under Solver.

[Rails] Help with model association
Hi, I'm very new to RoR so my question may be bit stupid. I'm trying to create application that could serve as training log. So I have "Trainee" who goes to a gym. What he/she does is a "Workout" (and there is a bunch of them in list to choose from). Now there are many Trainees in a gym at a same time having different (or same possibly) Workout. So I have a table with Trainees, table with Workouts and I would like to join them in Trainings ( Trainee id_1 did Workout id_2, Trainee id_2 did Workout id_4, both at 6 pm on 28.12.2008). One Training has many Trainees each with different or same Workout. Trainees and Workouts are connected together by join table with one additional value of date and time of training. At the beginning my idea was this class Trainee < ActiveRecord::Base has_many :trainings has_many :workouts, :through => :trainings end class Training < ActiveRecord::Base belongs_to :workouts belongs_to :trainee end class Workouts < ActiveRecord::Base has_many :trainings has_many :trainees, :through => :trainings end But I don't want to create new Trainee with new Workouts, both would be more or less stable (list of Trainees and list of Workouts to choose from). I would like to add new Training, choose date&time, choose Trainees (one or more) and attach Workouts to them (same or different to each) (so multiple Trainees on one Training, each Trainee with one his own Workout). My queries should be something like - who did Workout_id1 with best time - which Workouts Trainee_id2 did in last 30 days - who attended Training on 28.12.2008 etc. Is my association model correct ? Could I use join table directly like this ?.

You will see something that looks vaguely like: map.resources :tasks That creates routes that match /tasks/1/edit Oh cool... I just realized that using the RESTful routes created by map.resources, and using the default route at the end of routes file, you would get to exactly the same place via: http://localhost:3000/tasks/1/edit and http://localhost:3000/tasks/edit/1 If that sort of thing bothers you, you could "consider removing [the default rules] or commenting them out if you're using named routes and resources" Oh, I just saw the part in your email about the "named routes and resources". Since you are using the scaffold, you are using named routes and resources, since that is what is considered to be the best practice by those who brought you Rails. Google "RESTful routing" and you will find much more information than I could provide in an email. But, in a nutshell, the "map.resources" command at the top of the file creates a bunch of routes for you that map to the 7 actions you found in your controller.

But by then I figured you would have noticed it yourself :-) The error message is produced because @task evaluates to nil. Something somewhere in the #form_for helper tried to call @task.id, which got evaluated as nil.id, which triggered an exception, which displayed an error message indicating that you probably didn't want to do that. I see empirically how it works; however, I'm still curious how does > Rails "know" whether I've called respond_to in my edit method? > > The respond_to stuff has to do with "Web Services" whatever those are. (Keep in mind, I'm a newbie here too.) From what I've intuited so far, web services seem to like to exchange data using XML. I don't really know why #edit doesn't include a call to respond_to where each of the other 6 actions do, except to note the use of #edit in the world of RESTful routing. In that world, when you want to create a new record in a table, you are first presented with a view of a blank record (via the #new action). When you click on the "Create" button, the #create action gets invoked. In the same vein, when you want to edit an existing record, you are first presented with a view of the existing record (via the #edit action). When you click on the "Update" button, the #update action gets invoked. My guess is that, in the web services world, one would never invoke an "update" action without first having some idea of what the data looked like and that one would probably have learned that via the #show action, so that rendering something in XML for #edit is not necessary. In the web brower world, the "show" view displays data on a page while the "edit" view would presumably display a form (with the exact same data) allowing the end user to change the data and submit an update. That's my guess anyway. --wpd --~--~-~--~~~---~--~~ You received this message

If I look at the routes that were auto-generated for me, I see: map.connect ':controller/:action/:id' which would lead me to believe that the URL should be: http://localhost:3000/tasks/edit/1 while semantically it makes more sense to apply the edit action last, I don't see how that maps to the code.

I'm not quite sure what "named routes and resources" are and whether I'm using them. >"Invoke the 'edit' action in the 'tasks' > controller, and, by the way, set the 'id' parameter to '1'". > > When your #edit action is invoked, it searches the Task table in your > database for the entry with an ID of 1.

Yes, it does this, but when the template is rendered, it causes the error below, which I assume is because '@task' is not defined, although I don't really understand the error message. Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id Extracted source (around line #3): 1: Editing task 2: 3: <% form_for(@task) do |f| %> 4: <%= f.error_messages %> 5: 6: > If you leave the #edit action in there, but don't do anything in it, the > default behavior is still to render a template with the same name as the > action. yup. same behavior. > If you leave the code in there as written, the #edit action will fetch > the > row from the Task database with the specified ID.

[Rails] member on has_one or has_many
Hi,
I was wondering if it is possible todo something like this in the
routes file:
map.namespace(:admin) do |admin|
admin.resources :dashboard, :only => [ :index ],
:has_one => :something, :member => [ :action => :get ],
:has_many => [ :something_else ,:more_something ]
end
The problem is the member in the has_one declaration, the member is
added to the dashboard and not the something controller. I tried
wrapping in [] and {} but no luck...
I got it working using :dashboard do BUT I would like to have the
nice :has_one :has_many...
Anyone?
PS I guess If I want to use :only and :except for the has_one this
also applies...

[Rails] text_field or text_field_tag
Hi,
I'm watching Ryan Bates' forms screencast #1, and he says that I
should use text_field when I'm updating an object, otherwise
text_field_tag.
How about this: I'm looping through each row of a table and displaying
form for each. (but there's only one form, because I want it to be
submited all at once). Now I'm not sure how should I do it, so far I
have something like text_field("item_#{item.id}", "title", {:value =>
item.title});
Is this a good way?

Try creating a task, and then editing it. You should find that, when you
remove the lines from "Edit", you don't get information that you previously
entered when you created the task.
If you look in app/controllers/application.rb, you will find that
ApplicationController is a task that you derived from
ActionController::Base. You should be able to find documentation about
ActionController::Base at http://api.rubyonrails.org/
>From one newbie to another...
Look at the links created in the index view for your tasks controller. With
the default scaffold, you should see three links to the right of each task
listed: Show, Edit, and Destroy. If you mouse-over the Edit link, you will
probably see something that looks like: http://localhost:3000/tasks/1/edit.
That says to the routing system in Rails (through the magic of the code you
wrote in config/routes.rb) "Invoke the 'edit' action in the 'tasks'
controller, and, by the way, set the 'id' parameter to '1'".
When your #edit action is invoked, it searches the Task table in your
database for the entry with an ID of 1. Then Rails, by default, will render
a view (a web page) named "edit". You can see the template for that web
page in app/views/edit.html.erb.
If you completely remove the #edit action, the default behavior is still to
render a template with the same name as the action.
If you leave the #edit action in there, but don't do anything in it, the
default behavior is still to render a template with the same name as the
action.
If you leave the code in there as written, the #edit action will fetch the
row from the Task database with the specified ID. The #edit view will then
have some data to show when it displays the form.

[Rails] ApplicationController: understanding generate scaffold
I'm new to Rails and I'm trying to understand the code created by
generate scaffold. I'm using Rails 2.2.2.
$ ./script/generate scaffold Task description:string
generated the following code in app/controller/tasks_controller.rb
class TasksController < ApplicationController
# GET /tasks
# GET /tasks.xml
def index
@tasks = Task.find(:all)
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @tasks }
end
end
# GET /tasks/1
# GET /tasks/1.xml
def show
@task = Task.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @task }
end
end

format.html # new.html.erb
format.xml { render :xml => @task }
end
end
# GET /tasks/1/edit
def edit
@task = Task.find(params[:id])
end
I noticed that the edit method is missing some code. If I remove those
same lines from each of the methods above. The code still works, why?
I couldn't find ApplicationController in the API docs at

I would agree that organizing deeper can be useful. But if so, the groups should be meaningful to your application, not arbitrary (which from your account "physical" seems to be). Smaller Rails applications don't do it, not because of any bias against it, but because they don't have 188 models to organize. 10 to 30 models is not hard to manage. And while generally it makes sense to keep everything in one application, keep in mind that it is possible to have more than one application and still share a table, a model or pass data between them. Depending on the schema and requirements, a 188 model application might be happier as three 60 model applications that share a User model/table. To give a non-Rails example: Google needs to keep track of my login, but that doesn't mean Google Maps and Gmail have to be one application. > He also evangelizes Postgresql instead of MySQL I would say that's his personal preference and not gospel.

Generators are there to help 90% of the time. The other 10% you'll have to do by hand, modify what they give you or roll your own. Once you get the hang of it, you'll see that it will only take a minute or two longer to do it without generators.

Otherwise you will spend a considerable amount of time maintaining code and keeping options open for the future that you may never use. It is not hard to implement the "enterprise recommendations" you mentioned (grouping controllers and models, upgrading databases, etc.) when you find you need them. Don't burden yourself with them until you do. Ideally a framework will allow you to build your application fast, not burden you with features you may never use, but still keep your options for feature modifications and application scalability open for the future. I think Rails does that well. Kevin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Re: add an editor on my application
Hi I have limited experience with FCKEditor -- http://www.fckeditor.net/ and slightly more exp with tinymce -- http://tinymce.moxiecode.com/ but in my experience the better solution is to use textile -> http://redcloth.org/ & http://wiki.rubyonrails.org/rails/pages/RedClothsince they are simpler and then harder for users to break.

[Rails] Re: index => nil params jumbled *sometimes*
as rendering the view seems ok, i suppose it has something to do with the logic behind it. so far your posted params show, that your controller receives the second entry as first parameter, the first entry gets split by the third, which is not yet saved or the id got lost. additionally: all this only happens for one user. honestly: this seems strange. some points to start looking for an answer: - are you able to reproduce the error, if you login as that user? - what about that user? does he have any 'special qualities' (like: has special rights or uses lynx to access the site *g*)? - does your session variable contain the correct data? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This seems like a relatively good idea, could have a string-key called
family_tree or something and just do find_by_family_tree("abe|homer|
bart")
This doesn't quite feel right - it seems like the only info you should
need to keep is a person's parent (from which you can then find their
parent and so forth). It might also lead to some very long strings
eventually!

This is what I'm doing at the moment - I'm using the "betternestedset"
plugin, so have access to a "children" method that returns an arrary
of children. Will this have all been pre-fetched efficiently? And if
so, is the iterative code the way to do it?
tree = ["abe","homer","bart"]
person = Person.find_by_name(tree[0])
if tree.size > 1
1.upto(tree.size - 1) do |i|
person = person.children.find { |child| child.name == tree
[i] }
end
end
@person = person

Basically from reading the book, Dan doesn't believe in the "Rails Way" because he hints that it lends itself to quick and dirty code; not dirty in the sense of old PHP/ASP code, but dirty in that it doesn't care about scalability from the start but as an afterthought. Although his book does seem more geared towards using Rails in an enterprise environment, as opposed to the usual new startup. He does mention that, as a developer of an original "big Rails site" he's speaking from hindsight in his own projects and that he would architect them properly to scale from the start. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Box models

I don't consider myself a guru.
In looking at your CSS there could be a lot of cleaning up done.
Example. you declare font-family in many places.
You could make a "main.css" and do
--
body {
font-family: Geneva, Arial, Helvetica, sans-serif;
font-size: medium;
}
--
That way your fonts are the same and since you're declaring it once
less to download.
You could go further and make a "type_001.css" and just declare all
your typography in it.
When you want to change you font change the file to say "type_002.css"
that way the cached css won't be pulled and you wonder why the type
hasn't changed.
You could do the same for:
reset (http://meyerweb.com/eric/tools/css/reset/)
layout (positioning)
style (colors and other eye candy)
my 2 cents

[Rails] index => nil params jumbled *sometimes*
My app has a timesheet, which is a collection of many TimeCards, based
on a Date.
I have one user that can create new TimeCards just fine, except on
three associated Jobs. Each time he saves he gets a 500 error.
Looking at the params, they come across jumbled and my processing
method chokes:
(The first "time_cards" entry is correct, the second is split by the
third)
Parameters:
{
"date"=>"2008-12-17",
"time_cards"=>[
{
"job_id"=>"3107",
"time_card_entry_type"=>"Field",
"time_card_date"=>"2008-12-17",
"id"=>"285875",
"note"=>"Akron e-rate cable project counts/ FSR
presentation",
"hours"=>"2",
"user_id"=>"178"
},
{
"time_card_date"=>"2008-12-17",
"id"=>"285774",
"user_id"=>"178"
},
{
"job_id"=>"3089",
"time_card_entry_type"=>"Field",
"time_card_date"=>"2008-12-17",
"id"=>"",
"note"=>"progress drawing and spec revision",
"hours"=>"2.5",
"user_id"=>"178"
},
{
"job_id"=>"3107",
"time_card_entry_type"=>"Field",
"note"=>"Akron e-rate cable project counts",
"hours"=>"2"
}
]
}
The form is a partial that uses index => nil, and it works for all
other users, except this guy, on these associated Jobs.
%tr.entry
- fields_for "time_cards[]", entry, :index => nil do |entry_form|
= entry_form.hidden_field(:time_card_date, :value => @date)
= entry_form.hidden_field(:user_id, :value => session
[:timesheet_user].id)
= entry_form.hidden_field(:id)
%td= entry_form.select :job_id, available_jobs
%td= entry_form.select :time_card_entry_type, allowable_types
%td= entry_form.text_field :hours, :size => 5
%td= entry_form.text_field :note
I've scratched my head on this one for weeks, anything look out of
order?

[Rails] Re: How to get select_tag value in controller?
I suppose you're using prototype, so you just need to get the value of
the select box.
$("id-of-the-element").getValue()

[Rails] Re: NameError: uninitialized constant Digest::SHA2
Just try the echo statement and check what it is printing in the model.May be the sha1 will be using Time.now function also in addtion to its own coding.The time that value is authenticated and the time when u are checking the authentication will be different The solution is if the sha1 is encoded with time also just remove the Time.now function from it.Then this will solve the issue.i have also faced the similar problem when i used acts_as_authenticated plugin.

instead of just looking for someone that is willing to implement your models and methods, why don't you just give it a try first and ask if you encounter any problems? start by defining the relations between models (has_many, belongs_to, ...). add callbacks (after_save :convert_price) and methods (def convert_price). all along write some tests to see if your code is working correctly. if you're stuck somewhere, come back and ask for help. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Preventing a form from submitting on ENTER
Hi - I have the following problem: my app has a form that acts as a filter to a table on the page, so that the user can search any value in the table (via text box) or use select lists for more specific search. The form is being observed by an observe_form helper that runs every 1-2 seconds or so. It's all still in testing. I noticed that when I hit return while in the textbox, the form posts and redirects me to an action unknown page. I want to remove that functionality so that hitting enter wont do anything -- any idea how to do it?

That's an excellent piece of advice, and it is what I also use, but it doesn't work all the time if there is a special background.

never work, since it will just try and pass that file through erb even
