similar to: Formatting a float with a set number of decimals

Maybe it''s all in my head, but I''m having the strangest little issue ever. My pricetags in my rails app are always whole numbers. Rails seems to completely ignore my decimal input. So as a consequence, 10.41 becomes 10.00, always. Here''s some worthwhile stuff: within my 004_create_products.rb file: :price, :decimal, :percision => 2, :default => 0 And calling

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, When i use the ''delete_all'' function to remove a few rows from my database, it causes a deadlock on the sql server. The delete seems to be successful, it then redirects to the ''view'' page, and the record does appear to be deleted as far as the ''view'' rails page shows. BUT if i go into sql query analyser, i can''t do a

I wish to create a matrix of all possible percentages with two decimal place percision. I then want each row to sum to 100%. I started with the code below with the intent to then subset the data based on the row sum. This works great for 2 or 3 columns, but if I try 4 or more columns the number of rows become to large. I would like to find a way to break it down into some kind of for loop, so

In my save function in my (ajax!!!) controller, i''ve got a bit like this: if ... flash[:notice] = ''NOT SAVED: This month is locked'' render :partial => ''edit'' else save it... redirect to ''show'' action.... ... If i try to save an entry for a locked month, it correctly brings me back to my edit action with the

How can i run and get the value from the following sql: select avg(my_field) from my_table where which_year=''0506'' and which_week <= 21 and my_foreign_key_id=10 cheers -- Posted via http://www.ruby-forum.com/.

Any ideas with fixing this? Doesn''t work properly, although it doesn''t throw any runtime errors. # Methods added to this helper will be available to all templates in the application. module ApplicationHelper def options_for_months(selected_month)

I have a function i want to be used in both views and controllers: def year_to_fiscal_year(year) # converts, say, an integer 2003 into ''0304'' year.to_s[2,2] << (year+1).to_s[2,2] end Where should i put it ? -- Posted via http://www.ruby-forum.com/.

Here''s what i''m trying to do: Have 3 dropdowns up the top of a page, being: year, month, department, and group. Also a button underneath that called refresh. When you click refresh, it finds the 1 row of data from the database for that year/month/dept/group and populates the fields into a set of textboxes below. Then you can edit what is in those textboxes, and click a

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?

Warning: newbie post I've scanned the archives and found some discussion of porting some code so it's integer based as opposed to floating point based. Has anyone looked at using Intel's Integrated Performance Primitives or their Math Kernel Library in an effort to optimize the code across all x86/XScale processors?

I''m using form_remote_tag like this: <%= form_remote_tag \ :update => "div_id_dataentry_bottom_ajax", :loading => "document.getElementById(''wait'').innerHTML=''Loading...'';", :url => { :action => "dataentry_bottom_edit" } %> And it makes this code: <form

Hi, I know that to make a dropdown box automatically submit when you change the value, you do this: <select ..... onchange="this.form.submit();"> BUT i''ve got an ajax form, and if i do the above trick, it simply reloads the ajax partial into the whole screen, rather than into the div where it is meant to go. I''ve already got it all working so that if you click

Hi (again!) I have a function which gets passed the name of an instance variable, and spits its out all nicely formatted.

Is there a better way? eval("@" << inst_var_name << "." << field_name <<

Hello, When I am writing in sqldf or RSQLite I lose the decimals in my matrix. The only way I can get decimals is by multiplying by 1.00000, etc. I have tried manipulating the options, but it is only effective once I multiply by 1.0000. I appreciate any suggestions! Thanks! Example: z <- sqldf ("select ST, SUM(AGEP*PWGTP)*1.000000000/SUM(PWGTP)*1.00000000000000 as wgtage from ss09

Hello list, I'm just getting started with R, and I'm trying to determine how R treats large numbers that have decimals. Take the following two examples: > x <- c(999999999999999.9) > sprintf("%.5f",x) [1] "999999999999999.87000" > y <- c(9999999999999999.9) > sprintf("%.5f",y) [1] "10000000000000000.00000" I realize that I have
