I''m releasing a very small plugin that allows you to specify default values for fields in models. Ordinarily, you might do this in your schema, I guess, but then it''s awkward if you need that on a serialized field or need your default values calculated somehow. So you can do something like this: (repeated from an earlier post and the README) class Mixture <

I''m looking for a way to select a default value from a select box, like this: select("user", "role_id", Role.find_all.collect {|r| [ r.name, r.id ] }, { :default_value => ''5'' } (of course, there is no ":default_value") If the form is being used on a ''create'' page, it should display a default in the select box. If

Hello, I''m working with a postgresql table CREATE TABLE elements ( id serial primary key, c1 text default f1(), ... cN text default fN() ); But if I use de lines @element = Element.new @element.save the values that element take are the nextval in the id field and nules in all the other fields. How can I get the defaults? (but without rewriting the

What''s the best way to set the default value of an optional local variable in a partial template? In the past I''ve used <% foo = default_value unless (defined? foo) %> But http://api.rubyonrails.org/classes/ActionView/Base.html says *not* to use (defined? foo) and instead use (local_assigns.has_key? :foo) thus <% foo = default_value unless (local_assigns.has_key?

Hi, I am trying to implement a dict lookup for disabled accounts, where both the passdb lookup and the disabled lookup is done in the same passdb. I was hoping that this configuration would work: passdb { name = redis driver = dict args = /etc/dovecot/dovecot-redis.conf.ext } --- uri = redis:host=127.0.0.1 key disabled { key = users/%u/disabled/%s format = value

Greetings, I have a class that should allow you define some default values. It seems to make the most sense to do this environment.rb since its the default app configuration. It currently looks like this: Settings::DEFAULT_VALUES.merge!({ :setting_one => ''foo'', :settings_two => ''bar'' }) The problem is in development mode, the values are only there for the first request after launching webrick. After the first request the entries have dissapeared form the class. In develo...

Dear puppetteers, I am having a philosophical question about parametrized classes. When building modules, one wants to be as flexible as possible, to try to target as many puppet flavors as possible. This is our target: - Foreman users, using foreman as an ENC with smart variables (or potentially any other ENC, but I would say this is the most widespread one). - Pure Puppet''s site.pp

line 212 of postgresql_adapter.rb is return Time.now.to_s if value =~ /^\(''now''::text\)::(date|timestamp)/ i don''t think this will work. in postgresql the field ''now'' is pinned to the SAME TIME for the duration of a transaction. eg. if you do begin transaction; insert into t values(42, ''now''); # sleep one minute

Hello, I am trying to set up file-dictionary based quotas while supporting the SETQUOTA IMAP command. I am using the following configuration : ---- plugin { quota = dict:User quota::file:%h/Maildir/dovecot-quota quota_set = dict:file:%h/Maildir/dovecot-quota } ---- which enables correct quota accounting + setting through SETQUOTA. A user's dovecot-quota file ends with the following

I want to write out a series of records to a text file so that I can quickly edit them and then upload then again into the database. To do this I am using YAML and some code that looks like this: item = Item.find 153 File.open( ''item.yaml'', ''w'' ) do |out| YAML.dump( item, out ) end This dumps out all the field names and values which are stored in the

Everytime a new record object is created i.e. Record.new, i want certain fields to be the same. Any idea how to do this? Thanks Chris -- Posted via http://www.ruby-forum.com/.

Hi, I am processing tick data and my code has stopped working as I have increased the size of data being processed. Now I am receiving error for basic tasks in RConsole: > a = c(1:1000) Error: evaluation nested too deeply: infinite recursion / options(expressions=)? My R code worked fine with 50 stocks and 500,000 rows per stock, but when I increased this to 50 stocks and 5,000,000 rows per

Dear Sir or Madam, I am in 2nd year of my PhD in bioinformatics, after taking my Master?s in computer science, and have been using R heavily during my PhD. As such, I have put together a list of certain features in R that, in my opinion, would be beneficial to add, or could be improved. The first two are already implemented in packages, but given that it is implemented as user-defined operators,

I still want to get this into Rails for all connection adaptors, but for now I''ve hacked my own addition on for just PostgreSQL. The following code extends every Column object returned by MyModel.columns to support a new #required? method, which indicates if the column may or may not be null. The following is a huge hack - suggestions on a cleaner way to add this functionality

Hi everyone, I have a repeatable core dump when running dovecot on FreeBSD in the specific scenario described below. Dovecot is linked against MIT kerberos in /usr/local/lib/, whilst PAM is linked against Heimdal in /usr/lib/. My expectation was that dovecot authentication using GSSAPI would use MIT kerberos in /usr/local/lib, whereas PAM authentication is independent from dovecot and would

Regarding the anonymous-function-in-a-pipeline point one can already do this which does use brackets but even so it involves fewer characters than the example shown. Here { . * 2 } is basically a lambda whose argument is dot. Would this be sufficient? library(magrittr) 1.5 %>% { . * 2 } ## [1] 3 Regarding currying note that with magrittr Ista's code could be written as: 1:5

Thanks for the answers, I?m aware of the ?.? option, just wanted to give a very simple example. But the lapply ??' parameter use has eluded me and thanks for enlightening me. What do you mean by messing up the call stack. As far as I understand it, piping should translate into same code as deep nesting. So then I only see a tiny downside for debugging here. No loss of time/space efficiency

Just starting a new thread so that it''s easy to follow. I just submitted a patch at trac to add a new class method called "set_default_values" ( not a great name I think ), which lets you do all kinds of crazy stuff with setting default values. This ticket is at http://dev.rubyonrails.org/ticket/9093 and example pastie is at http://pastie.caboo.se/81925 It also lets you make use of other attributes ( set by supplying attributes to...
