Okay, the SQL does not work... wrong default values for bit datatype 
says Postgres...

But if I just do:

   prop_accessor :done, TrueClass

then the table is created correctly, and I can insert values for that 
column correctly BUT I can't retrieve them! For some reason I always get 
'false' back as a result, even if the column is 'true' in the database.

Hello everybody,

I have been using Nitro for a small GIS-related project and it's proven 
of great help! We have managed to develop simple web services that 
interact with multiple databases and other web services in less than an 
hour!

I'll try to invest some time in the next weeks to improve some bits in 
the source code and maybe help with the documentation.

At last, after all these years of fustration, we have a nice web 
application platform to work with :-)

Thanks,

Do you know that there is a scaffolder and a FormBuilder (like Nemo) in nitro
that utilizes the Og metadata? (btw did I tell you that the new Nitro
will ROCK? :)

Could you give a little example on how you generate just a session-id?

That's just fine ;-)

I've now taken a look at your FormBuilder. How exactly can I define 
those meta-attributes? I saw, you use meta[:ui] == :textarea...
Ah sorry, I found it already myself:

   prop_accessor :attr, :ui => :textarea

will do.

Thanks.

Sure:

  # Calculates a unique id.
  #
  # The session id must be unique, a monotonically 
  # increasing function like time is appropriate. Random 
  # may produce equal ids? add a prefix (SALT) to stop 
  # hackers from creating session_ids.
  
  def create_id
    now = Time.now
    md5 = Digest::MD5.new
    md5.update(now.to_s)
    md5.update(now.usec.to_s)
    md5.update(rand(0).to_s)
    md5.update(Session.session_id_salt)
    md5.hexdigest
  end

As you can see the FormBuilder is under construction, If you have any
good ideas, let me know :) I do have some cool ideas for this, you
will see in Nitro 0.10.0 :)

Thanks. Will use this as default session-id generator until I include ISAAC.

Mine is called OgScaffolder::Editor. I factored the rendering into 
following methods:

   * render (top level)
     -> calls render_property for each property
     -> then calls render_buttons

   * render_property
     -> calls render_label
     -> then calls depending on the property type one of
        render_numeric, render_string, render_bool etc.

This makes it easier to customize layout. My editor also does not render 
a <form> tag, this can be done by adding a FormDecoration to the 
component. The advantage: You can put as many Editors on a page as you 
like, and when you hit a button, you don't loose what you entered in the 
other forms. If you click Save or Cancel, my editor returns (answers), 
so that you can use it like this:

   def show_editor
     call Editor.new(Customer.new), :on_answer
   end

   def on_answer(res)
     ...
   end

Of course you can use it without using #call. But then you have to wrap 
it with a AnswerDecoration.

Then I'll have a OgScaffolder::ListView which shows multiple 
domain-objects in a table.

Regards,

   Michael

Seems to me, we are writing the same code twice :( For example I am planning
to do a TableBuilder that does this. We should probably synchronize our efforts
and build something together. But then again, perhaps it is better If
you go alone and create your version, so we can compare the two
aproaches afterwards.

PS: updating Nitro 'docs' right now, this is pain in the a**.

Hi,

The version you send me has still problems.

If I reload the domain object, the boolean value is always "false".

It's due to:

   UPDATE..... done=true

And then in self.read_prop (Pg backend) you do:

   't' == res.getvalue(...)

Why not just provide a install.rb file as I did last night? ;-)

Would be wonderful if RPA would still be alive... I am not sure whether 
it's alive, but in this respect it's a great project.
