Problem with paginate, include and foreign keys
Hi all,
Solaris 10
Ruby 1.8.4
Rails 1.0.0
Postgres 8.1
postgres driver 0.7.1
I''m having a problem with getting paginate() to properly pick up an FK
constraint properly.
I don''t seem to have this issue with ActiveRecord, however. Consider:

id bigserial,
start_date date unique,
max_slots int default 40,
primary key (id)

rebuild_index is returning {}
Previously when I used to build index i used to get false in return.

Now I get this.

Following changes took place.
1) I moved my app from FCGI to mongrel.
2) I moved my app to capistrano.
Before moving to capistrano the code was

using select() to relate tables
I''m sorry to be asking trivial questions, but I''m new to RoR and am
hooked :), so I''m very impatient to get things up and running.
given two related tables, "pcs" and "venues" (venues have many PC''s and
each PC belongs to one venue only) I can use a select() to present venue
names in the "new PC" form along with other PC details to

FormBuilder in rjs
I have a page, which renders a partial that contains a ''State'' drop
down list. Upon change, it re-renders the ''City'' drop down, re-
populating it based on selected state_id:

How to load a selection list into the method new of a controller?
Hi friends!
I''m relatively new with Rails and I''m struggling for a long time with this

Nested objects not propagating from view
I thought I had this fixed, but apparently not. It works okay from the
console, but not from the view. I have the following:

t.string "first_name"
t.string "last_name"

Working with date_select ...
I am a little confused about the best way to work with date_select. I see that
in my views it generates a simple input form that allows for the entry of year,
month and date information. If I just leave it at that, great!
But what if now in the controller, I want to work with the date information. I
actually want to take the user input date and compute a new date some number of
days in the

datetime_select, is creating an instance of the Time class
Hello
It seems that datetime_select, is creating an instance of the Time
class. Why would that be?
I found this while building a site where people can create vigils
(prayer vigils, peace vigils, etc). When I added a validation method
that compared start_date to created_at, it generated the error:
ArgumentError (comparison of Time with DateTime failed):
I was able to put a breakpoint in the

Validating Foreign Key
Howdy,
I''m a Rails beginner working on my first significant project with RoR.
I''m trying to figure out how to validate a foreign key (you know, make
sure the row actually exists.)
However, validates_associated doesn''t seem to be what I want to use, nor
does it work...

Include with two references of one model of the same table
Hey guys,
I just came across this oddity, not sure what to make of it yet, but
I think it might be incorrect behavior. When doing a @inst.find(:all,
:include => ["hometeam", "awayteam"] ...) hometeam and awayteam are two
references from a belongs_to that is of the same model and of the same
table. I will get a pgerror stating that "matches", which is

Multi-parameter assignment
Hi,
I''m trying to submit data from text boxes on a form to one variable in
my controller, in the same way that datetime_select has date(1i),
date(2i), etc for day, month, year, etc...
I''ve named my variables event[start_date(1i)] event[start_date(2i)] and

help with ActiveRecord joins
I''m working on a fairly complex join query and could use a bit of advice
from more expert users of ActiveRecord.
I have an events table with quite a lot of data, with has_many relations
to categories, age_groups, and event_images. In my first naive
implementation, each event had a date, so to load all upcoming events
efficiently, I''d do:

Simple range question
I have a model with a datetime field called start_date. I''d like to do
a find on the model so that it returns only records with the start_date
equal to the current day.
Something like this:
@foos = Foo.find(:all,
:conditions => //?? start_date equal to today''s date
??// ] )

How to display the error messages from the controller
I have a wizard which consists of two pages. To keep it simple let''s say
that the first page asks the user to select a state from the drop down menu.
In case the user doesn''t select any state, an error message needs to be
displayed.
Ideally I would like to do something like this.
def new

if selected_value == "-1"

Can't pass parameters to Ziya controller using url_for
Hi All,
I''m stuck yet again. I have an action on a controller that produces a
Ziya graph, which I call using the gen_chart() helper. However, I can''t
seem to pass more than one parameter through to the action.
