well you said that you would not use a constant submodule
<shevy>
yet there are plenty of constants
<shevy>
so how would you use them?
<sinequanon>
right, i'm suggesting that'd I'd have MyModule::RPL_WELCOME
<tmoore>
IMO if you're putting all of your constants into one Contants module... that's not that good
<sinequanon>
vs. MyModule::Constants::RPL_WELCOME
<shevy>
k so you put them all into what file exactly?
<shevy>
nope
<shevy>
I don't have to type the above; I include it of course
<tmoore>
put each constant with the code that uses it
<sinequanon>
^
<shevy>
so if you have 100 .rb file
<tmoore>
if you have lots of code all over the place sharing a constant, that's a design problem
<shevy>
how do you solve that?
nheinrich has joined #ruby
<twoshot_>
what about database connection strings?
<twoshot_>
that's not a design problem, and lots of code all over the place will use it

doesn't matter if it's 10 files, 100 files or 1000 files... you need some degree of modularity in your code or all hope is lost
<tmoore>
I challenge your assumption that code all over the place should be using a database connection string :-)
<shevy>
well you did not answer the question - if different files require different constants, how do you make use of that? do you put individual constants into separate .rb files and only load those constants?
<tmoore>
you want one class that manages your database connection
Macaveli has joined #ruby

"4:56 PM <tmoore> put each constant with the code that uses it"

i'm sorta confused why you'd include constants, rather than just declaring them
bthesorceror has quit [Ping timeout: 255 seconds]

tmoore that does not solve the issue that different part of the code can require different and multiple constants
<twoshot_>
well, for instance, in c#, i suppose you could wrap creation of a database connection
<shevy>
sinequanon they are already "declared" - in their own namespace
<twoshot_>
ok, yeah, i think you're right

k you guys show me your big projects?

the size of the project is irrelevant
<shevy>
k so you don't have anything to show

haha
<shevy>
what is the maximum amount of constants you have used in any of your projects so far?

i think you're missing the point

OK assuming that you're trolling and going back to work
<shevy>
you can assume all you want - as a factual statement: you don't have a big project to show where you use lots of constants.

those are all in: cinch-2.0.3/lib/cinch/constants.rb

I’m trying to learn about OOP in ruby and the tutorial I’m following states ….

<jheg>
The second use case for modules we'll look at is using modules as a container for methods, called module methods. This involves using modules to house other methods. This is very useful for methods that seem out of place within your code. Let's use our Mammal module to demonstrate:
Wolland has quit [Ping timeout: 246 seconds]
<jheg>
the code they use to demonstrate is ....
<jheg>
module Mammal
<jheg>
...
<jheg>
def self.some_out_of_place_method(num)
<jheg>
num ** 2
<jheg>
end
<jheg>
end
<jheg>
which can be called like value = Mammal.some_out_of_place_method(4)
<jheg>
I don’t understand what the ‘self’ part in the method within the module is for

jheg: in the context of a method definition, 'def self.method_name' means you define the method on the singleton class of 'self', which has the effect of defining a method you can call on the class or module itself, rather than on instances of a class or objects that have mixed the object in

I have an array of strings, each string should be used to get the class name and the parameter name in rails

I have now, @model = %w[team player tournament].detect { |model| model.classify.constantize.find_by_id(params["#{model}_id"]) }

<alex88>
just asking out of curiosity

with as little as 3 classes I'd probably not go all meta but just copy & paste. the whole thing seems smelly to me, but I don't know what you're doing.
<alex88>
pontiki: yup that's what I wanted to fix
<apeiros>
re no meta: @model = Team.find_by_id(params["team_id"]) || Player.find_by_id(params["player_id"]) || …
<alex88>

accessors allow you to give and get attribute information without requiring you to know how the attribute is implemented internally to the object
<slap_stick>
does anyone know why that might be?
<slap_stick>
it's almost like ** is no longer meaning recursive in rspec

jheg: it's not customary in rails to call your setter/getters set/get
<teotwaki>
jheg: if you blindly trust input from other objects, just use attr_writer
<slap_stick>
nope in the rakefile itself to the object created when i create a new task, wchih is |t| so t.pattern = "**/*_spec.rb" however reading the dogs it defaults to that anyway
<DefV>
We prefer def name; end, and def name=(name); end
Macaveli has quit [Ping timeout: 240 seconds]

and just calling dog.name and dog.name = "bad"

i haven't modified the file and it was working literally before i upgraded rspec to the latest versino, if i remove the latest version it works again

ah thanks for the tip DefV

we don't have the loads where it'd become interesting

so our emphasis is on ease of maintenance, limiting complexity. hence pondering to switch to a pg based queue. we already use pg and I intend to replace all db related stuff with pg -> one db we have to know how to deal with instead of the current 5
