before_create is after_validatation :on => :create , when it should be before_validation :on => :create
In ActiveRecord''s callbacks, methods within a before_create callback
are called after the validation, but before the model is created.
This was an intentional design decision, but I think it was the wrong
one. What do you think?
When I think of before_create, I think of before_validation :foo, :on
=> :create, but, by default, before_create is synon...

DB trigger vs before_create
...g trouble figuring out which approach is better.
I have the following tables: products, orders and line_items.
Every time an Order is placed, the quantity field in the products
table has to be updated for each LineItem in the Order. One option is
to use DB triggers which is not as portable as using before_create in
the Order model. But with before_create I cannot use fixtures for
orders and line_items since they don''t use before_create as models do.
Has anyone any recommendations on which approach is better?

before_create firing twice on a save - RC2
I have a unit test which fails using Rails 1.2RC2, because a method marked
by the before_create filter is firing twice when my ActiveRecord is saved.
Is a before_create filter supposed to cause multiple invocations? We have
assumed it is called once, and only once, when the object is created, in our
code (but we unit tested it to make certain).
This is one of three issues I have with my...

before_create question
...r, Registration, Event.
User has_many Registration, Event has_many Registration, and
Registration belongs_to User and Registration. So far, so good.
There''s a registration deadline on a Event though, a few days before
the Event occurs.
So, I have this:
class Registration < AR
def before_create
errors.add_to_base("Registration deadline has passed") unless
event.can_still_register?
end
end
The weird thing is, if the registration deadline has passed, the error
gets added to the registration object, and calling save! throws no
exception, but the registration object doesn...

why doesn't this work (setting attribute in "before_create")
Hi,
Can anyone spot why the below doesn''t work?
* I have a "created_by" column in my create table in the dB
* I have a "before_create" line, which definitely gets called
* I tried a few different ways to set the "created_by" attribute in the
model but it doesn''t seem to work, i.e. doesn''t appear in the database

Working around/with Restful Authentication
I''m using Restful Authentication, and the code to create a user is
pretty straight forward - there is a before_save action and a
before_create action:
before_save :encrypt_password
before_create :make_activation_code
But for some reason when I try to create a user programmatically in
the controller like this:

a problem with before_create and validations
I stumble across some strange problem.
I have a model with a virtual attribute file_contents that is a string.
The model has validates_format_of :file_contents, :on => create, :unless
=> no_contents? (The method that returns file_contents.nil?)
Then, I have a before_create callback, where I get my model''s title and
description by parsing file_contents, and do write_attribute for title
and description.
The problem is, that it hangs the server. Forever. Looks like
write_attribute triggers validation again, and then before_create is
called again, and we get...

before_create return value breaking object.save: rails bug?
I know that usually when people say ''i think i found a bug in
rails/ruby'' they''ve done something dumb. I''m wondering if this is the
case here, but this does seem like a genuine rails bug to me.
In my user model i have a few different before_create callbacks. In one
of them, if it happens to return false (just because the last statement
in it evaluated to false), then the saving gets blocked - i can see the
db transaction rolling back. However, this doesn''t affect the results
of calling .valid? on the object, so i get this situ...

ActiveRecord::RecordNotSaved - bizarre behaviour.

As you can see, there''s no INSERT SQL generated, which is the root cause
of the problem.
In my user model, I have the following call back:

calbacks on models
Hi, I''m having some strange behavior on callbacks when testing with
RSpec2. On my test, when I create a resource using the #create method
the callbacks related to #before_create are not called. If I go to the
console and I try to type the command Resource.create(client_uri:
"http://example.com") all works fine.
There are no mocks around, and I can''t understand if this is a normal
behavior using RSpec, if its due to Mongoid or something else.

insert value of primary key into another field before record is saved
...I want to also assign it to another
field of the same record called ''sequence''. So if the primary key of
the record is 23, then the sequence should also be 23. But the record
is not created yet, so it doesnt have an id yet.
I tried doing this in subbook model:
belongs_to :book
before_create :add_sequence
def add_sequence
self.sequence = self.id
end
But that didn''t do anything at all when running the seed task.
Any idea how to update another field with id of record before that
record is saved to database?
Thanks for response

How do I validate using associated objects?
This doesn''t make any sense to me anymore. I have an Upload that
belongs_to a Comment. Within my Upload model I expect to be able to
access the associated comment with comment.foo. I can only seem to do
this AFTER validation. I''m assuming before_create takes place between
validation and updating the database, because when I try to access
comment.foo within the validate method, I get "You have a nil object
when you didn''t expect it! The error occured while evaluating
nil.board".
Now I am using single table inheritance,...

Compute date during before_validation_on_create
..._date
- so, added callback before_validation_on_create
- in this method I do :
end_date = begin_date >> 12
- unfortunately, beeing in before_validation the actual self.begin_date
have not been type casted - It''s always a string
- unfortunately again, I can''t put this code in before_create because
the validation will not pass because (before_create is called after
validation checks)
I could remove the validation against end_date but I don''t like this...
What will happen if the computed end_date goes wrong ?
Thanks for your ideas

Suggestion: `before_save on: :create` should either work or raise an exception
...a
silent failure. I''d like to suggest that it either be made consistent or be
made to fail loudly.
The issue is that to do something before validating, but only when
creating, you use `before_validation on: :create`, but to do something
before saving, but only when creating, you use `before_create`.
I have tried to use `before_save on: :create`, and it does not produce an
error, but it does something unexpected: it saves before create **and**
before update. This isn''t really something an application''s tests would
catch, I don''t think.

Created_on and updated_on in a non-ActiveRecord model
...Well, the thing is that I also want the behaviour of the created_on and
updated_on columns, that get modified automatically before saving.
The problem is that I have my own "save" method and it does not work
(remember this is not a real ActiveRecord model). I''ve tried to set the
before_create and before_updated methods but they does not work (see
code below).
So
is there any way to do it automatically?
Thanks.
