Has_many questions

Rails
1

I am working on a project where I am uploading data about houses and
need pictures to accompany it. I have a model for ‘housing’ and
another one for picture.
my housing class
has_many :picture

and my picture class
belongs_to :housing

My questions are

  1. I want to use one form to create a new house with a bunch of
    pictures. how do I do this

  2. a scaffold can generate the traversal of my housing table in my
    view, but how do I display the pictures.

  3. I was told to use attachment_fu, and the tutorial was great at
    telling me how to upload an image, but it didn’t show how to link an
    image to another model.

  4. when I generate a scaffold via “ruby script/generate scaffold
    housing add_housing” why don’t the forms contain the logic to upload
    pictures with the housing data.

I have been relying on books and google searches to get me started,
but they have only discussed single models, and I haven’t found a good
resource for doing what I need. Any help would be greatly appreciated.
It doesn’t even have to be the answer, so long as it points me to
something that will explain what is going on and help me get this done.

    Don’t. Create another action for that. It gets pain in the ass to handle
    image post data on edits :slight_smile:

    Use the docs, Luke! with attachment_fu you do @picture.public_filename.

    Well…
    @picture = @housing.pictures.build(params[:picture])
    @picture.save

    Don’t expect scaffold to be ‘oh mighty God’. It’s only for starters and
    isn’t suited well for most cases in life.
