similar to: Call an helper method from a controller

Back in 2.1.1 everything was sweet: Loading development environment (Rails 2.3.3) >> include ActionView::Helpers::NumberHelper => Object >> number_to_currency(12.3) >> "$12.30" Then I upgraded to 2.3.2 and: Loading development environment (Rails 2.3.3) >> include ActionView::Helpers::NumberHelper => Object >> number_to_currency(12.3) >> 12.3

Any ideas why I would get an error in a RJS helper on view helpers such as number_to_currency. Example: # my_template.rjs page.help_me # my_helper for my_controller def help_me number_to_currency(10) end I have also tired page.number_to_currency but that doesn''t work either. Cheers, Nicholas

Hi Gurus, I have a class, specified in models cart.rb, which doesn''t inherit from anything--it''s just a container class Cart ... I just discovered I can''t call number_to_currency in that class. Any idea how to "include" it in my code? I tried ActionView.number_to_currency without luck. I could kill a few lines of non-DRY regexp code in cart.rb if I could

I was wondering if this is possible. I have a model (Item) that contains products. These products have prices that I''d like to format using number_to_currency. Rather than doing this several times inside the view, I thought it might be nice to do it once inside the model. The item table has an field called regular_price which holds a currency amount. I would like to do something

Hi, Is there a way to call helper methods in a controller? I want to do something like this in my controller Class MyController < Action.... def my_method string = link_to "some_url", :controller => "home", :action => "command" end end link_to is an ActionView helper method and it seems that I couldn''t access the method in the controller

Is there a simple way to format your data in the .rhtml file? I come from a PHP/Smarty background, and in the templates, I''ve used what is called "modifiers" to format data. {$price|currency_format} # displays in currency format {$description|truncate:"100"} # Truncates the description after 100 characters It seems like the template (rhtml) would be the ideal

Hi all, Apologies in advance if I got this one wrong, I''m still just a newbie ;-) Going through the Apple ADC RoR tutorial it suddenly occurred to me that the ''number_to_currency()'' helper method was not DRY streamlined. Scenario:: The "number_to_currency()" methods options hash works great when I need to dynamically display different currencies when I

I know, I know, they''re not allowed to. But here''s my problem. I''ve got a really simple model with two fields, name and price, which I want to show in a form select drop-down. "collection_select" takes a ''text_method'' parameter, which is the method in the model that gets its value placed in the <option> tag. Because I want to show both

Hi, I''m trying to use number_to_currency in one of my models, but i''m getting the following error: undefined method `number_to_currency'' for #<Product:0x396d680> Obviously, my Product model can''t access number_to_currency -- is there something I need to do to make it available? Thanks so much for your assistance. -- Posted via

I work in the UK and therefore most of my currency figures will be in UK pounds. I realise that to format a number to a currency format I can use: number_to_currency(amt, :unit => "?") but it would be more convenient to set ? as the default currency symbol. What is the best way to do that? Should I edit line 39 of this file:

I am using the number to currency function because i live in the uk and the company want me to only show values of the pound of course.I have created all my application using ruby script/generate scaffold_resource.... I have come across with a problem... this code is in my applcation: def number_to_currency(number, options = {}) options = options.stringify_keys precision, unit, separator,

so I am trying to sum month over month the amount that a user has posted. So for example: User 1: Jan $3000 Feb $4000 March $1500, etc. I can get this to work if I sum totals (aggregate of all users) but just not by user. Here is my code in the controller: def index @users = User.find :all, :order => ''name ASC'' @deal_groups = Deal.find(:all).group_by {|t|

I was trying to write a wrapper for number_to_currency to return currency in pounds. I used a helper class to do this. def number_to_pounds(amt) number_to_currency(amt, :unit => "£") end This works fine, but I am trying to understand why I can''t use a symbol to pass the values. I thought symbols were like pointers. (you now know I am a newbie). def

Using File.size(myfile) I can get the size of the uploaded file in _bytes_. Does anybody know of a function to convert bytes into a more human readable format? If I had a wish list for a "file_size_in_words()" function, it would do this: 10752 bytes becomes "10.5 Kilobytes". 2213814 bytes becomes "2.1 Megabytes". 238 bytes becomes "Less Than 1 Kilobyte".

I was trying to access rails functions (number_with_precision) from an irb session. It can''t find the method. How do I load the libraries ? TIA LS -- Posted via http://www.ruby-forum.com/.

Hello I''ve encountered a little problem with zeros using the decimal data type Specifying a scale of 3 and inserting a number with 3 zeros after the point (for example 12345.000) it gets correctly stored in the database, but rails insists to show me the number only with the first zero after the point (12345.0) There is a way to tell rails to not truncate at the first zero?

Hello, What is the easiest way which enables usage of decimal comma "," instead of decimal point (".") . I would like to force all RoR views to display float numbers with comma instead of decimal point and also to allow insertion of float numbers with comma in forms.
