Hi..Guys new plugin again


Guys new plugin again

Foreign Key Associations is a plugin that automatically creates
associations based on foreign-keys. The associations are created at
runtime-ie. as your ActiveRecord models are loaded-so they will always
be up-to-date.

For example, given a foreign-key from a customer_id column in an
orders table to an id column in a customers table, the plugin

Order.belongs_to :customerCustomer.has_many :orders
If there is a uniqueness constraint-eg unique index-on a foreign-key
column, then the plugin will creates a has_one instead of a has_many.

For example, given a foreign-key from an order_id column with a
uniqueness constraint in an invoices table to an id column in an
orders table, the plugin creates:

Invoice.belongs_to :orderOrder.has_one :invoice
Additionally, if there is a position column in the child table, the
parent association will be created with an order clause.

For example, given a foreign-key from a order_id column in an
order_lines table containing a position column, to an id column in a
orders table, the plugin creates:

OrderLine.belongs_to :ordersOrder.has_many :lines, :order => :position
The plugin also supports the creation of has_and_belongs_to_many

For example, given the tables product_product_categories with foreign-
keys to both the product and product_categories tables, the plugin

:categoriesProductCategory.has_and_belongs_to_many :products
And finally, notice that in one of the previous examples, the
association name used for the Order.has_many is :lines and
not :order_lines. More specifically, the plugin removes the prefix
from has_many and has_one associations if the the name of parent class
forms a proper prefix of the child class name.

The plugin fully supports and understands the following active-record
configuration properties:


To install using SVN:

Stop flooding the group with these posts.

good work buddy,

flood away…you did the hard work and should be able to get some
acknowledgment for it

announcing developments like this is just what this mailing list is

high fives all round…down low for Rein H.

Neither this nor any of the 15 other posts this person has made in a
15 minute span have been their work.

Besides, the link to the plugin (that he didn’t write) isn’t even

I agree with Rein H., stop flooding…

“One question at the time, and wait till you get answer before asking a
new one”

sorry guys, I had not seen all the other posts…

stop flooding foo

For the record, I’m all for announcing open source developments here.
I was subscribed to ruby forge for over a year before it got to be too
much. I plan on making a few such announcements myself. :slight_smile:

However, I’m less keen on announcing other people’s hard work and
conveniently forgetting to give them credit.


I was 2 seconds from marking all of Jhonny’s posts as spam when I
that they are all on topic…

Stop flooding
