hi,
I'm new to Rails (I'm comming from Django) and I'm looking for
something equivalent to Django's Formsets (http://
docs.djangoproject.com/en/dev/topics/forms/formsets/) and Inline
Formsets (http://docs.djangoproject.com/en/dev/topics/forms/modelforms/
#using-an-inline-formset-in-a-view)
does Rails have anything like this?
for those who don't know Django, a formset is an html form that
represents several records at once, like this:
given an Article, a formset with 3 items would be like:
<form action="...">
<tr><th><label for="id_form-0-title">Title:</label></th><td><input
type="text" name="form-0-title" value="Django is now open source"
id="id_form-0-title" /></td></tr>
<tr><th><label for="id_form-0-pub_date">Pub date:</label></
th><td><input type="text" name="form-0-pub_date" value="2008-05-12"
id="id_form-0-pub_date" /></td></tr>
<tr><th><label for="id_form-1-title">Title:</label></th><td><input
type="text" name="form-1-title" id="id_form-1-title" /></td></tr>
<tr><th><label for="id_form-1-pub_date">Pub date:</label></
th><td><input type="text" name="form-1-pub_date" id="id_form-1-
pub_date" /></td></tr>
<tr><th><label for="id_form-2-title">Title:</label></th><td><input
type="text" name="form-2-title" id="id_form-2-title" /></td></tr>
<tr><th><label for="id_form-2-pub_date">Pub date:</label></
th><td><input type="text" name="form-2-pub_date" id="id_form-2-
pub_date" /></td></tr>
....
</form>
(please, ignore the clutter. just the INPUT tags matter)
and when the request is submitted, I just have to do this in my
controller to get it parsed:
ArticleFormSet = formset_factory(ArticleForm)
if request.method == 'POST':
formset = ArticleFormSet(request.POST)
(now, the formset object has a list of 3 Article objects)
thanks in advance,
Cesar
