Hi, now I have working a form for upload images. I'm using
'nested_form', 'paperclip' and 'aws-s3' for storage. All works fine
but I would get better. The problem is that the user select the images
that want upload but until the user do submit the images is not
uploading. It is not nice, because
I'm trying to use select('DISTINCT *') but it doesn't work. Sure, de
INNER JOIN between Post and Tagging result of table that all rows are
distinct. If we supost the next:
Posts Table
ID TITLE
1Foo
2FooFaa
TAGGINGS Table
ID POST_ID TAG_ID
1 11
1
Haven't tried it, but maybe grouping on posts.id would do the right
thing?

Hello Matt, thanks for the answer. I've try it and it works fine
except when you call to count method later. I've solve it well:
scope :finded, lambda {|id| where(:id = id)}
scope :tagged, lambda
Great Valery! I've solved it.

Hello,
I've a usually structure with Post has_many Tags through Taggings. All
works well and clean. But I'm having problems with the next scope on
Post:
scope :tagged, lambda {|tag_id| joins(:taggings).where(:taggings =
{:tag_id = tag_id}) }
All works fine for call of only one Tag like:
Hello, I have a model like this:
class Car ActiveRecord::Base
def color(c)
where(color = ?,c)
end
end
Suppose that I want to show the red and blue cars. I could do
something like this:
@cars = Car.color('blue') + Car.color('red')
The problem I'm finding is that now, @cars is an array
Thanks cpr. It isn't work for multiple select control but It's okey
for a classic select.

Other solution is change the params hash for setup like
accepts_nested_attributes_for is expecting. I don't know which is the
best solution for do it. In short, I want to create multiple nested
objects by selecting from a list.

Hello, I'm triying to set a form but I'm having problems.These are my

I would advise against a strategy that could ever be ambiguous, even
if it looks unlikely at the moment. It would likely bite you at some
point in the future, or even worse the developer who comes hereafter,
can you imagine what he/she would say about you when he realised the
problem and
