I'm wondering if it's worth the server time when updating a record to retrieve the existing record, loop through the fields checking for changes and only putting the changed fields in the update query? (I am using MySQL & PHP.)

Thank you
You can do that with javascript.
AFAIK, you cannot insert inline formsets into the middle of a parent form .
You would have to manually extend the admin template (change_form.html) and hard-code positions into it .

I am looking at using Ruby on Rails for a storefront that has to make use of existing data, but I can create my own database schema if I need to. A lot of the fields in the existing data are char(1) emulating a boolean field (i.e. Y/N) for, I believe,...

Can't you just wrap it in your database engine with a view or stored procedure to produce a consistent interface to your application?

Hi,
I have a form that uses jQuery to submit an ajax post and it serializes the form that is sent up. The code looks like this:

I just want to modify the value of the field that without changing what the user typed("action"); var formArr = form.

Although I'm sure some people may frown on it, I'd go with option 2, but reworded like this:
select UpToE.*, (D * D * E) as F from ( select UpToD.*, (2 * D + 4 * A) as E from ( select A, B, C, (A * B + C) as D ) as UpToD ) as UpToE

In much of the code I have seen (on SO, thecodeproject.com and I tend to do this in my own code), I have seen public properties being created for every single private field that a class contains, even if they are the most basic type of get; set; like:...
