Condition on fields_for

Dear All,

Pretty sure that I have been quite earnest in updating my application
with
particular concern for n+1 issues, otherwise, hopefully, more complete
use
of of Rails 3.0 model associations. If one really scrutinizes my
models,
you will see that I have not been totally thorough… a matter of time
and
expectation of how the application will grow.

Nevertheless, I am offering the app level code for the site at
GitHub - emcgurty/echomarket: Goodwill resource for lending, borrowing, trading and donating nonperishable/ethical items. At some levels I am very proud
of
what I accomplished, eg, using scope as a manner of determining ‘type’
and
utilizing fields_for.

At the controller level, I am not happy with my use of :_destroy. I
expected that it’s use would be much more dynamic. But what I have,
works.

Otherwise, I owe great thanks to members of this group. You provided me
with a huge impetus to improve my site. I live is rural Virginia, where
I
must rely on internet sources for my information. Some of it good, so
much
of it misleading.

Oh! My site: www.echomarket.org. (I haven’t fully implemented JQuery
toward
client-side validation, so the site is still presented as ‘Under
Construction’, but I offer a link for the eager.)

Sincerely,

Liz McGurty
