Hi all-- I''m starting a new Rails project and I''m preparing to import it into my local Subversion repository. In the past, I''ve just imported the entire set of files generated by ''rails'', but I''m starting to wonder if that is the best way to approach things. For instance, it makes sense to add the log/ directory, but probably not the

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would like to extract an image BLOB from my database and display it alongside some other information on my ''edit'' page. I read the information here http://wiki.rubyonrails.com/rails/show/HowtoUploadFiles and that was really helpful. However, it still isn''t clear to me how I would get access to the image in my views if

I have a database column given as: t.column :change_address, :boolean The user interacts with this using a checkbox, but wants confirmations to read: Change address: Yes In an isolated case something like: @obj.change_address ? ''Yes'' : ''No'' Would work fine but this is peppered throughout scads of forms and boolean fields. The first step I took at DRYing

value_to_boolean(value), does not always return a boolean value, only when true. 150: def value_to_boolean(value) 151: if value.is_a?(String) && value.blank? 152: nil 153: else 154: TRUE_VALUES.include?(value) 155: end 156: end If value is contained in TRUE_VALUES then it returns true(TrueClass). But if value is

Hi! I try to use a layered webservice and I want to get back an array of users; In the API I use: api_method :listUsers,:returns=>[[User]] in the service: def listUsers User.find(:all) end Result in soap mode: Don''t know how to cast TrueClass to Object Result in XML-RPC mode: You have a nil object when you didn''t expect it! You might have expected

Hey All, very simple question for you folks ;) I have a @commutes object that for each record there is a bit value set (0/1) to denote if an accident occurred. What I want to do is have it display "Yes" or "No" when I view the listing of commutes. I can get it to display the bit value just fine with <%= commute.accident %> but how can I get it so that when a record with

Hi All, Im playing around with Jugganaut but stuck at the first step. Seems the jugganaut push server requires json (which I have installed) but it cant find it. Following the docs, I have installed json and then try to run the push server. jonathan $ ruby script/push_server script/push_server:37:in `require'': no such file to load -- json (LoadError) from

All, Rails 1.1.6. Any AR find() call that generates a SELECT * type query against a table with a DATETIME column in SQL Server whose value occurs before 1970 will fail, because of the coercion of SQL Server datetime types to Time values in Ruby. See sqlserver_adapter.rb line 490 (record[col] = record[col].to_time if record[col].is_a? DBI::Timestamp) If I remove the coercion (just commenting

Dear all, first I would like to tell you that I've been using R for two days... (so, you can predict my knowledge of the language!). Yet, I managed to implement some stuff related with the Long-Tail model [1]. I did some tests with the data in table 1 (from [1]), and plotted figure 2 (from [1]). (See R code and CSV file at the end of the email) Now, I'm stuck in the nonlinear regression

Hi, I am following the guide here: http://guides.rubyonrails.org/contributing_to_ruby_on_rails.html I have an ubuntu 11.04 VM setup, installed rvm, and ruby (ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]). Pulled down the rails from github and created a 3.0 branch: $ git branch --track 3-0-stable origin/3-0-stable $ git checkout 3-0-stable I can run the non-db tests ok, all pass

1) The Pareto P(alfa) distribution is defined by its density f(x|alfa) =alfa*X^(-alfa-1) over (1 to infinity). Show that it can be generated as the -1/alfa power of a uniforme variate. Plot the histogram and the density. 2) The Poisson distribution P(lambda) is connected to the exponential distribution through the Poisson process in that it can be simulated by generating exponential random

I am just trying to teach myself how to use the mle function in R because it is much better than what is provided in MATLAB. I am following tutorial material from the internet, however, it gives the following errors, does anybody know what is happening to cause such errors, or does anybody know any better tutorial material on this particular subject. >

Hi Puppet-Team, first thanks for this great configuration management tool ! My name is Matt and i am on creating a puppet plugin for openQRM. The basic framework is already existing and working well so far. Now, after having it working ok once i now ran into a problem that my puppet-clients do not get their configuration any more from the puppetmasterd. What i saw on the puppetmasterd logs is :

Dear R users, I have to call fortran program from within R (R 2.8.1 on ubuntu 8.10 machine). Suppose I have a fortran code like this (this is only a toy model, my working model is far more complex, but input/output is similar) DOUBLE PRECISION FUNCTION model(times, alfa, beta) DOUBLE PRECISION alfa, beta, times model=beta*sin(times)+alfa*cos(times) END FUNCTION which
