...n 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 < ActiveRecord::Base serialize :color default_value :color, [255, 0, 0] end m = Mixture.new m.color # => [255,0,0] Here''s the README: http://mdaines.com/svn/plugins/default_value/trunk/README To install: (as usual) script/plugin install http://mdaines.com/svn/plugins/default_value/ trunk Thoughts, comments? -- M...

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 the form is on the ''edit'' page, it should display the current value. Thanks, co...

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? :foo) %> Some have suggested <% foo ||= default_value %...

...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 default_value = } key user { key = users/%u format = json } passdb_objects = user passdb_fields { fail = %{dict:disabled} } Unfortunately, this will always set the fail passdb_field regardless of whether the disabled key returns its empty default_value. Removing the default_value setting will cau...

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 deve...

...the only data binding. But let''s say that within mymodule there is a define mymodule::mydefine that uses variable values from mymodule, let''s say mymodule::parameter1. I need to include mymodule to be able to use it, right? This is the example: class mymodule (param1 = ''default_value'') { } define mymodule::mydefine () { include mymodule ## just to make sure it was parsed before case (mymodule::param1) {blabla} } If you only use Hiera as a data backend, you''re good: if you need to override parameter1, you do it in the hierarchy, and the include does...

...53:54.290717 2005-03-03 09:53:54.290717 (4 rows) it looks like (from only reading the code) that table_structure will map the default values of each field in column_defaults.collect do |row| field = row[0] type = type_as_string(row[3], row[2]) default = default_value(row[1]) length = row[2] [field, type, default, length] end so, each time default_value sees ''now'' it will call Time::now.to_s - and this will be different each time. it may not be obvious right away since, if the code runs quickly and you are storing on...

The output looks something like this: - !ruby/object:Item attributes: image_height: '''' maximum_value: '''' minimum_value: '''' item_id: 153 default_value: '''' ... many more fields However I don''t want all these fields. How can I limit the YAML output to just include the fields that I want? I know that I can override to_yaml_properties to specify the fields that i want from a class. But that really only lets me...

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

...t. 7) Default values for S4 methods It would seem that it is not possible to set up default parameters for an S4 method in a usual way of definiton = function (x, y=5). I resorted to making class unions with ?missing? for signatures on the call, with the call starting with if(missing(param)) param=DEFAULT_VALUE, but it certainly does not improve readability or ease of coding. Thank you for your time if you have finished reading thus far. :) Looking forward to any answer. Yours Sincerely, Antonin Klima

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

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...
