"Remembering" link to redirect to after logging in
Hi,
Suppose I have a resource such as http://localhost:3000/topsecret/data
that requires the user to login first.
What I did was make use of before_filter to check and see if the session
variable is set with the logged in user''s id (similar to the example in
"Agile Web Development with Rails").
However while the filtering function does work correctly in redirecting

Autocompleter to read value from hidden field
I have an autocomplete field with road names (looking up in a database with
approx. 100,000 road names).
To limit the number of roads, i want an extra input field where to put
postal code.
I''m currently using <%= text_field_with_auto_complete %> for the field.
What is the best way in Rails to intercept the Ajax call and send the value
of the postal_code field?

Polymorphic Validations
Hi Everyone,
Ran into an interesting case last night, and I was hoping that someone
on the list here could give me some guidance.
I''ve got a Polymorphic association for Addresses (which can belong to
two different models).
The catch is, one model requires a strict, precise address, and the
other only requires a City, State and Postal Code.
I want to use :validates_presence_of :street,

Implementing a model with logging?
Hi,
I''ve been trying to work out a model (let''s say a StudentRecord) which
has a number of attributes, and the key thing I''m trying to do here is
to implement it such that you can actually view modifications made over
time by various users (think of it as a wikipedia style of logging).
Is there some provision in rails that''d provide this functionality for

Error when using form helper and child objects
Hi,
This is one problem that has gotten me stumped for quite a while. I have
an Item that has_many :DeliveryMethod, and what I seek to achieve is to
create a form that''d let me create an Item, as well as its
DeliveryMethods in 1 single form.
And so I tried something like:
<%= text_field_tag ''Item[DeliveryMethod][price]'', @Item.DeliveryMethod

Form field naming semantics question
Hi,
I have a question today regarding how the various form elements in
_form.rhtml are named.
I understand that for a database table "persons" with a column headed by
"name", then in _form.rhtml it will probably be like:
<p><label for="person_name">Name><br/>
<%= text_field ''person'', ''name''

Rails doesn't validate create_model or build_model (has_one association)
I''ve got User has_one Shop. Rails is not validating when I tried
create_shop or build_shop, neither in the browser nor the rails console.

Using onSubmit tag in form_tag?
Hi guys,
I have been working on a form that would use javascript to validate the
data before submitting it, and from my view.rhtml I have a statement
like this:
However such a statement generates a HTML tag that looks like this:
<form action="/users/Login?onSubmit=validate%28%29" method="post">
Seems like Rails thinks it is a parameter instead of an option, so

Database schema question
Im setting up a very basic rails app and have a question about the needed
migrations & associations.
Basically, my app is an occasion reminder service that emails users when
occasions that they select or input are coming up.
Occasions will be selected from a checkbox type list or alternatively
manually input by the user (name and date of the occasion).
Users can have_many occassions.

stuck on a validates_presence_of unless issue
i have a person object. Persons don''t need to have addresses, but if
they have any address field value, they must have them all. So I have
something like this:
validates_presence_of :street_address, :city, :state, :postal_code
unless :address_blank?
address_blank? checks whether all of the address fields are blank.
If I run a test like this, it works:

validates_uniqueness_of and create atomicity
Hi folks,
I have a question regarding validates_uniqueness_of, and similar
before-filter-like events attempting to guarantee some DB state prior
to modification.
>From my reading of ActiveRecord, validate_uniqueness_of appears to
cause a SELECT on the underlying table attempting to ensure that a

validate_uniqueness_of {combination of fields} ???
I''ve looked at the validates documentation and it appears that validates_uniqueness_of works on only one field at a time. So I can, for example, validate that "sam" is unique to the record set, and that "smith" is unique to the record set.
My problem is that each record includes two fields, the _combination_ of which must be unique to the record set, but each of

customize validates_uniqueness_of
I need to modify the validates_uniqueness_of function so that it will
check that the string is unique but only in its own category.
For example right now I have

so let''s say I have the :title "Title 1" already in the database with
the :category of "1"

Matching failure in merge()
Hi!
I've done a merging between 2 dataframes using merge():
delme <-

After realizing some problems in the resulting dataset,
I've found that the problem was that, in some cases, there
was no match between the by.x and the by.y elements, despite the
