[Rails] Re: no such file to load -- my_extensions (MissingSourceFile)
Many thanks to you both - indeed, I was being a muppet, and it's exactly as you suspected, namely I'd forgotten to copy across a file. Grep'ing for the file name helped me track it down. Thanks again and Merry Christmas! -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] no such file to load -- my_extensions (MissingSourceFile)
I have a Rails application runnng on one machien quite happily, using
Ruby 1.9.1-p243 and Rails 2.3.3. I copied the app and config folders to
another machine, on which I'm also running 1.9.1-p243, but via RVM.
Whenever I try to launch the Rails application ('server', 'runner',
'console') I get the error message no such file to load --
my_extensions (MissingSourceFile).
Based on one googled suggestion I created a nearly empty file,
$ROOT/config/initializers/my_extensions.rb
but this did not help. I'm also wondering if I need to create a
'wrapper' as I've seen this mentioned int he contect of using Rails and
RVM - but I can't see what I would need to do for, say, 'ruuner'. All
advice gratefully received.

[Rails] Passing arrays between controllers/views
I have a controller that produces (through its associated 'view' displays summary information of) a number of arrays. On that view page I would like links to other pages, one per array, which shows more detailed information on the array in question. I tried passing the array as a parameter to a link and whilst I think that would have been fine for small arrays for a large array I was getting URI too large. Since I don't have admin rights to the web server I don't think I can tweak the http buffer settings, and anyway I don't think very long URLs are elegant. What other ways are there to achieve what I am after? One suggstion I saw was using a session - is that the best way (the Ruby way) to pass data between controllers? Any suggstions gratefully received. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

I've had a quick look at the documentation and I see it makes use of fields :lft and :rgt -I guess I can use aliases for these, along the lines of :lft = my_field, as I don't have control of the database? Also, do you know if awesome_nested_set will be faster than what I'm doing currently, or just more convenient? regards -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Recursive self-referential many-to-many relationship
I have a 'Circuit' table, and a 'Glue' table to perform a many-to-many
join on the circuit records, such at a circuit can have many subcircuits
(its component parts) and many supercircuits (circuits which it itself
is a part of).
has_and_belongs_to_many :subcircuits,
:class_name = Circuit,
:join_table = circuit_glue,
:association_foreign_key = PTR_component,
:foreign_key = PTR_circuit
has_and_belongs_to_many :supercircuits,
:class_name = Circuit,
:join_table = circuit_glue,
:foreign_key = PTR_component,
:association_foreign_key = PTR_circuit
With this, I can do successfully things like
my_circuit.subcircuits[0].name
but if I try
my_circuit.subcircuits[0].subcircuits.any_method
... I get a NoMethodError: You have a nil object when you didn't expect
it!
The objects in the cct.subciruits array do not appear to 'full' circuit
objects in as much as they do not repsonsd to 'subcircuits'
To build a recursive list of subcircuits I find I have to resort to
self.subcircuits.each { |sc|
subcirc_array.push(Circuit.find(:all).detect { |c| c.absid.to_s ==
sc.PTR_component })}
... which seems pretty slow and laborious. Any advice on how to speed
this up, and/or get ...subciruits[n].subcircuits to work as required?
Thanks in advance.

[Rails] Extending a module in a controller
I'm trying to extend Enumerable in my Rails app. I've started with just the controller where I wanted to use this method i.e. class LookupController ApplicationController module Enumerable def my_compress ... but when I visit the web page in question I get No method 'my_compress' for Array ... I'm probably doing something fundamentally wrong - what could/should I be doing? thanks -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

I'd check with the whoever admins the MySQL DB to find out what character set it's actually using. I think you can then tell the adapter to translate. Best guess is either US ASCII, or (more likely) Windows-1252 pretending to be ASCII. --Matt Jones Many thanks for the reply Matt. I used the console to determine that the db is serving up ASCII-8BIT e = Equipment.find(:first, :conditions = ['id = ?', 1234]) e.name.encoding = #Encoding:ASCII-8BIT I then set the encoding in /config/database.yml to 'ascii' which although it can't display special characters, at least it shows the page with ? in place of the accented charaters. I tried setting encoding to ascii-8bit and varieties of this, but each time Rails complained - so if anyone can tell me how to indicate ASCII-8BIT I'd be grateful. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Working round 'invalid byte sequence'
I am a very amateur Rubyist who, amongst other things, likes to use a simple Rails app to query my company's MySQL config database. The server I now use to do this has got 1.9.1 and Rails 2.3.3. I've now hit the 'problems' related to 1.9 and string encoding, which means that when Rails try to display, say, E acute characters, it throws an invalid byte sequence, namely ArgumentError (invalid byte sequence in UTF-8): Given that I only access the MySQL database over a private network and with a read-only account, is there some simple and easy way to suppress this issue? Without being an expert in this area (obviously) I guess that either I can try to tell Ruby to treat the MySQL data as an encoding other than UTF-8 (I guess US-ASCII but it could be trial and error to work out what), and/or I could add some rescue code to find (and ignore) bad byte sequences. I've tried to find recipes for both the above, but quickly get lost in the subtleties of it all! Any and all help appreciated.
