[Rails] Re: Subdomains
You can do that with request.subdomains inside a controller. See http://api.rubyonrails.org/classes/ActionController/Request.html#M000526 If you want to "change" your primary key (or the key used for search) try with to_param.

[Rails] Re: Postgres defaults to ID DESC, MySQL defaults to ID ASC
(My point of view) Order the result by ID is also a bad idea, if you switch to another ID schema (for example UUID, descending sequence, etc.) you must rewrite a lot of code. The ID is something the application must not "know", order for example by name, by a created_at field (and that have more sense if you want "the last created user"). Regards. Franco Catena.

[Rails] Re: How to Disable Pluralization
I also agree with that, I want to make my point cleaner. English is not my mother language (if you don't figure it out yet), and programming in Rails is often a pleasure, but if you want to program in Spanish for example, the pluralization don't work. For example the plural of Ciudad (City) is Ciudades, but is pluralized as Ciudads (awful). I asume that the question was for one problem like this, i don't "support" not follow the conventions either. Regards. Franco Catena.

You can rewrite the inflections using ActiveSupport::Inflector.inflections (http://api.rubyonrails.org/ classes/ActiveSupport/Inflector/Inflections.html) and do something like mapping the plural of all words to the same word.

[Rails] Re: is f.submit in a form_for newer than submit_tag?
All the method in the form helper have his "object implicit"
counterpart, for example you can call text_field(object_name, method,
options = {}) or f.text_field(method, options = {}) and the object
used is f.object (the parameter of form_for @something), they produce
exactly the same output.

[Rails] Re: habtm association and accepts_nested_attributes_for
Try using the ID inside (this works for me):
params = { 'form' => { 'name' => 'paul', 'dni' => '17002034z',
'projects_attributes' => {
'1' => { 'id' => '1', 'name' => '', 'cost' =>
'25000' },
'2' => { 'id' => '2', 'name' => '', 'cost' =>
'3400'
An element with an ID is considered to be updated instead of created.

[Rails] Re: Automatically delete oldest post of a specified tag
You really need to delete the post? With :limit => 20 in your find is
not enought?. If the answer is a double yes, then you should use an
ActiveRecord callback (perhaps after_save

[Rails] Re: Renaming a file inside a zip
There is no method to directly rename a directory, you must use the
rename in every file between the directory like this:
Zip::ZipFile.open('my.zip') do |zipfile|
zipfile.file.rename 'original_dir/orignal_name.txt', 'new_dir/
original_name.txt'
end
And after that you can remove the original directory.

You can read the Agile Web Development With Rails (http://
www.pragprog.com/titles/rails3), is a very good book. It explains step

[Rails] Re: Listing of Category error
You must declare a has_many :categories in the Post model and a
belongs_to :post in the Category model (if the category table has a
post_id column, if not keep reading). If you don't do that, you need
to create a categories_posts table with two columns: category_id and a
post_id.

[Rails] Re: Translation inside models?
Inside a model is used like this: I18n.t(:username_in_use) You can also put it in the translation yml like this: es: activerecord: errors: messages: taken: "ya está en uso" There are more examples in: http://github.com/svenfuchs/rails-i18n/tree/master/rails%2Flocale Regards.

[Rails] Re: Can you run a find on an existing hash?
In the Enumerable's find_all method will be:
@products.find_all { |product| product.category_id = 2 }
This method returns an array, the find method returns only the first
match. This approach is not the best if you have a lot of products, in
that case you will use the ActiveRecord's find and let the database do
this work in a more efficient way.
Regards.

[Rails] Re: default values for new table entry
You can do this in the controller:
@foo = Foo.new(:parameter_name => true)
And then this in the view:
form_for(@foo) do |f|
f.check_box :parameter_name
