Hello-- There must be a better way to do this. I have a class method in my model that finds averages and does a few calculations using find_by_sql. The problem I¹m encountering is that all computed columns from MySQL come back as type string. E.g., def self.find_averages(domain_id) if @@domain_average return @@domain_average else @@domain_average =

Hi i''m using ferret to enable geographical postcode. I take a postcode and distance in miles from the user, strip off the outcode and then retrieve the associated x y coordinates in metres from the db. Then i get two temp x''s and y''s and search for all results that are within the box, see code below. Problems start to occur when i search on big distances so for

Thanks for reporting the bug below. You''re absolutely right. Renamed Range#to_s implementation to #mocha_inspect and checked first and last respond_to?(:to_f) as you suggested. Sorry for the delay - I wasn''t monitoring the rubyforge trackers. I am now! Should be fixed in revision 99 of trunk. -- James. http://blog.floehopper.org ---------- Forwarded message ---------- From:

Hey Guys, Again, I am just learning Rails, so I am asking advice here. I have a model called Company which has many Owners. The Owners model indicates the name of the owner and their share (as a percentage) of the company. The total shares for any one company can not be more than 100%. So if I have 10 owners each with 10% of the company and I update one of the owners and set their share to 11%,

Basically, I''m trying to crop multiple images out of a remote/original scene.. Think flickr ''tagging'', only, the pixs in the tagged boxes become their own unique images.. by way of simulating an upload from the controller using attachment fu.. can''t quite figure out the specific method in fu that would allow me to do this.. I''m so near the edge right

Lo there all, i have a function that builds a bunch of markers to go on a google map. I would like to update them with rjs. Here is what i have so far. def map_main_layout @zoom = params[:zoom].to_i @zoom = 14 if params[:zoom].nil? @map = GMap.new("map_div") # @map.control_init(:large_map => true, :map_type => true) # (inserts map control) # place

Dear all, I wrote a wrapper to a FORTRAN program using R. The main program uses a text file (~200 lines) as an input describing the simulation to be run. I typically generate the file once with the right parameters using a combination of file(), paste(), cat(). This is fine, and it works well, however I then need to update only a few values in the file many times (~200 times,

Looks like my first question a couple of days ago wasn?t very clever asked, at least very sucessfull.... So, anyway...i will try it again: I have to prefix that I am far away from fully understanding the overall concept yet, and there?s no way to get some hints in the www so far, at least my resaerches dont lead to any helpfull stuff. image_controller.rb: def create MiddleMan.new_worker

Hi, Just thought it was weird that Ruby doesn''t automatically cast ints to floats. Seems so un-rubyish irb(main):006:0> 12/16 => 0 irb(main):007:0> 12.to_f / 16.to_f => 0.75 Jeroen

Good day. I have spent almost 2 days on this issue. I have asked everyone from my Rails expert to my Javasript expert and we can not for the life of us figure out the issue with this one form element. I have a form which contains several readonly/disabled (firefox/ie) form elements. ALL elements in the form are updated correctly EXCEPT this one form element. The form element in the view looks as

I just updated an old app from 1.2.6 to 2.0.2 and I''m having an rjs problem. I have one page that has 2 submit to remote buttons, one to do a price override and the other to remove the lineitem. Everything is working perfectly before the update but now the price override doesn''t update the page. I''ve verified that the price_override method still gets called because

Hi all, I just noticed that in ActiveRecord::ConnectionAdapters::Column.type_cast[1] (and type_cast_code[2]) the type casting for float columns simply does value.to_f, whereas all the others have a rescue or call out to a method, the default implementations of which have rescues or enough logic in that I don''t think they''d fail. Imagine the following: create_table :vehicle do

I''m stuck in a catch-22 type problem. I have an insert form for a table that uses the validation in the model. i.e. When you click submit on the form and haven''t filled in the required fields then you get the nice rails error messages saying "field can not be blank". This works fine until I introduce some more logic. What I''m trying to do is to validate

I''m storying amounts of money in my database as cents. So I have custom accessors in my model, for example def actual_amount read_attribute("actual_amount").to_f / 100.0 end But when I use <%= text_field ''item'', ''actual_amount'' %> I get, for example, "3600" instead of "36.00". If I ignore the helper, and

I can''t use active record or anything. I need to validate inside the controller. I thought I could use to_f in the string method. The problem is that for a value of 1.3fsfs it returns 1.0 . I thought it would be consistently 0.0 . I can get a hack around it but looking for an elegant solution. Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I have a question about how ActiveRecord handles data types. When I enter text in a text_field (meaning, a field in the GUI) which belongs to a numeric field in the database, Active Record automaticly converts it to 0, because that''s what the to_f/to_i method of a string does. Is it also possible to have Active Record enforce the types, so that when you enter text for a numeric

Hi, I''m using a webservice in my application. How can I make it so that my application will only try to connect to the webservice for a certain period of time and then give up? Right now my code is using a begin-rescue-else but sometimes I get a "execution expired" error if the webservice is not available or takes too long to respond. Thanks, Peter begin service =

Good day. I have setup of a text field with auto complete and I need to grab the value from that text field and pass it into a method to update a row in a table. Here is the view: <tr> <td align="center" colspan="6"><%= text_field_with_auto_complete( :product, :product_code ) %></td> </tr> <tr> <td

Hi there I have a helper method in my Rails app that uses Minimagick as a plugin. All is fine except for the write step where I attempt to write the resized file to another directory. I get the error: "undefined method `to_str'' for #<Array:0x25221e8>" Here''s my resizing method: def display_thumb(product_id) # glob through images/books/thumbs dir to find

Hi there, I''m trying to grab all the contest_entries from a particular contest, and then grab all the appropriate contest_ratings associated with the songs and contest. The end result is an average score for each song involved in each contest.
