Hi all,
I am trying to model with AR some tricky db tables.
The table names are in caps and any constraints below or next to the
column.
The tables:
USERS
id PK
username
etc
PROFILES
id PK
user_id FK references users(id)
name
unique (id, user_id)
TELEPHONES
id PK
user_id FK references
I recommend keeping the table. Let me explain why and try to explain
how to set it up better.
This type of information is known at the outset of the application and
it sounds like it is unlikely to change significantly over time. As
such it could be pulled into a domain table, similar to states
You are right that everyone seems to disagree on this point. I think
validating the data is one of the most critical parts of an
application. I tend to validate at the db level and model level to
ensure integrity (as the app is not necessarily the only point of
entry to the db--psql prompt,
Give us more code, because this can be done in a single step.
Chaining method calls like that will return a single department object
(e.department). So it should be no different, and I have done similar
things in the past without trouble.
The only time this shouldn't work is if you try
I believe that paperclip actually stores a copy of the images in the
public directory by default. Once the html is rendered to the browser
the image requests should not go through the rails stack.
Let us know what firebug says. Browser load times are dependent on
many factors, and often the
Looks to me that you don't have the right model relationships defined.
in order to do e.department.customers, the Department class has to
know about the relationship with Customers. You should have:
class Department AR::Base
has_many :customers
end
I think this should work, if everything
I assume you know this because you asked just for the structure, but
the rake commands that Rick points you at will get you what you asked
for, but not things like FK constraints, other constraints,
transactions, etc. It will give you the schema though.

Agreed with Jeff.
The AR models really act as a wrapper class to DB tables. This helps
to add an abstraction layer to SQL and marshall SQL selects into
powerful ruby objects (the best part, in my opinion). With that in
mind create non-AR models as needed, and only use the AR models when

If you want it to be a constant, just capitalize it.

I agree with Colin above. Make a model level method to return the
data you wish to use in the view. Then within the view call

This could be the problem if the rest of the site works.

I assume that you have tried this but if not it is worth a shot. If
your model was filled with data prior to setting up ferret, then I
don't believe those rows will be indexed. You will need to build the
index or rebuild it. If you have not added any new data to the
database, you may very well

I agree with Marnen. The easiest way would be to just add a role
field to the user model.
I wouldn't mess with inherited classes or associations for what you
are describing.
But if you do, you really should use inheritance, as Marnen
described.
The only other table that I might consider would

I too choose PostgreSQL by default.
Here are some of my reasons.
1) It adheres more reliably to SQL standard than MySQL.
2) PostgreSQL has a better query planner than MySQL.
3) The number value zero in MySQL is treated NULL.
4) The default settings for MySQL make it case IN-sensitive.
5) Until
Hey all,
I am having a little trouble getting some referential integrity tests
to work well.
Right now, I am using Postgres as my database. I have generated
migrations for my tables and ensured referential integrity by using
execute commands. All is working well at the level of the database

It is also good to know that the save and destroy methods already
use transactions to ensure before and after callbacks.

I am currently have a 'products' table that has a :has_many
relationship with a 'photos' table.
I am uploading photos to accompany products. Right now, I upload the
photo, save the metadata to the 'photos' table and the image to the

, all the examples use numeric
values.
Any ideas?
Thanks,

Thanks for your feedback.
It is possible to ensure certain formats for the text column prior to
saving it to a database. This makes querying this data quite easy in
fact. Just because the user entered in a form like 2/12/1980, doesn't
mean it has to get stored in that fashionI would hope
Also consider the demands of a very very rapidly changing field, like
medical informatics. In this area, many prefer the flexibility of a
key/value system because adding columns constantly would be a
nightmare. Think off adding columns for every new lab test, imaging
type, procedure, etc. This
