From 3 fields :date input from forms to 1 field

Hi Rails community, here is my newbie problem (I’m migrating from PHP to
ruby due to framework and ruby syntax, but I’m having some problems with
“freedom” that a single php page offers):

I’m using the scaffolding technique (yea, I love it) to create a
webpage, but if I specify that a field type is :date, Rails auto
generate a form where the field of type :date is created through 3
fields: day, month and year.

I would like to use only one field (always) (will be something that I’ll
use for all :date field-type), a text field, where the date will be
written in dd/mm/YY format, how can I do this without writing something
in javascript that “set some hidden fields” (month and year) when you
write in the text field?

Are there a “general” way (as I’ve said, I’ll use this always instead of
normal way of setting dates)?

Thanks

How would you do that on PHP?

Scaffold will generate the form, but you can modify it as you please.
Change the form and make sure the parameters are OK in the controller
(yes, with tests)

Hope it helps.

In PHP I don’t have a predefined framework and so I don’t have rules to
follow (but this is not a good thing: I’m changing from PHP to Ruby also
for this reason), I have to write my own form and rewrite the way I use
it for storing informations

BTW, I’m quite sure that I’m not explaining very well but I’ve found
something:
In ActionView::Helpers::DateHelper there is “date_select” method, which
creates html tags formatted in a way, so the day selection tag will have
“name” attribute “calendar[mydate(3i)]”, the month will have
“calendar[mydate(2i)]” and so on. If I change these tags in my single
text field tag I will have “calendar[mydate]” and nothing else, but when
I send this information obviusly ruby should understand how to “split”
this date to store it: where should I do this (and where could I read my
submitted vars?)? In controller I only have
Calendar.new(params[:calendar]) in create method, so I think that params
should be “changed” in some way, is this the good way?

Yes, I don’t think there’s any other way to do that. You should parse
your params[:calendar][:mydateXX] and format them in the way you need.
I would do something like:
day = params[:calendar] .delete(“mydate(3i)”)
month = params[:calendar] .delete(“mydate(3i)”)
year = params[:calendar] .delete(“mydate(3i)”)
#I don’t really remember the order they are stored, but you get the idea
Then, do somehting like:
params[:calendar][:name_of_the_date_field_here] = Date.new(year, month,
day)
And then:
Calendar.new(params[:calendar]

But that’s just my first approach to this, maybe you can figure out a
better way to do it.

Hope it helps.

Thanks your suggestion actually is working for me (and better: I’ve
understood it)

These seems even better, but actually I have some difficults in
understanding it (I’m at the very beginning, so I’m having troubles in
understanding some processes)

Just to check that you have also seen the rails guides at
http://guides.rubyonrails.org/
The Getting Started, ActiveRecord Associations, Debugging, and Testing
guides are compulsory reading (and re-reading and experimenting till
it makes sense).
