Re: Sqlite3 on ubuntu

[Kyle King]

ActiveRecord has a built in pure ruby sqlite adapter (which is the  
*only* reason I sometimes use ActiveRecord over Sequel). Perhaps  
you're having include issues. Could you give the following a try?


Shoes.setup do
gem 'activerecord'
end

Shoes.app do
begin
require 'active_record'
require 'active_record/connection_adapters/sqlite3_adapter'
require 'user'

		ActiveRecord::Base.establish_connection(:adapter =  
'sqlite3',:dbfile ='test.db')

para User.find(1).id

rescue Exception
alert $!
end
end

Hi,

Noticed you are using 64-bit version of Ubuntu, did you build shoes
from source on your system?
Once I did that lots of ruby library problems went away.

   I've use
   Shoes.setup do
   gem 'activerecord'
   end

   to install the activerecord gem ,and got succes.
   when i use active record the connect the sqlite3, it says no
   driver for
   sqlite3 found,
   and I tried to
   Shoes.setup do
   gem 'sqlite3-ruby'
   end

   It does not work,I guess it's because shoes has install it
   already,since
   i can found it in /tmp/selfxx/

   I googled and not found a result.
   In windows ,it works fine.
   what happened to my ubuntu???

   Ubuntu Version : 64bit 8.04
   ruby verserion : 1.87 use ruby 
   1.86 use apt-get intall , is ruby1.8 

   some lib : i've already instal the libsqlite3

help with http post in shoes

[Vijay]

Hi,
I have a strange problem with using ruby http post in shoes block. I get a
connection refused - connect(2) error on trying to run the shoes app.
I am running the program on macOS and the problem seems to be
resolve-replace.rb: line 19.
Here's the code

require 'rubygems'
require 'erb'
require 'net/http'

Shoes.app{
   @http = Net::HTTP.new('localhost', 8080)
path = /remoting/ruby/Auth/logIn

args = {:userName = 'user', :password = '1'}

body = args.map {|k,v| #{k}=#{ERB::Util.url_encode(v)}}.join()

resp, data = @http.post(path, body, @headers)

para resp.response
para data
}

I can run the program without Shoes block and it runs fine.  What am I doing
wrong ?

Thanks for all the help.

Regards,
Vijay

PS - I understand that shoes recommends openuri over the ruby http class but
I would really appreciate comments on this issue

Re: Sqlite3 on ubuntu

[niedh]

Thanks all
I fix my problem after compile shoes from the shoes,
thanks to **Marc.** again.
yesterday i compile from source after Marc's advice,and try ,it's not work.
I found the reason today ,because I was still use the old version shoes
bin(which i download from shoes site ,may not work find on my 64bit ubuntu)
,not the newer compile one
:)

Thanks all again

instance variable voodoo

[Edward Heil]

this seems weird to me.  Am I wrong to be able to expect to use a  
method inside a shoes-derived class to assign a value to an instance  
variable?


Check this out:

==

class BugTest  Shoes

  url '/', :main

  def assign_variable
info assigning variable.
@foo = bar
info self is #{self}. @foo is #...@foo}
  end

  def main
title main
info in main.  self is #{self}. @foo is #...@foo}
button assign variable do
  assign_variable
  visit '/'
end
  end
end

Shoes.app

=


You run this, click the button, and get the following on the console:

in main. self is (#Class:0x12493b0::BugTest). @foo is

assigning variable.

self is (#Class:0x12493b0::BugTest @foo=bar). @foo is bar

in main. self is (#Class:0x12493b0::BugTest). @foo is




Where'd the value 'bar' in @foo go after the assign_variable method  
returned?

Re: + on our way to shoes 3

[Jenna Fox]

I would have thought the rubygems support and native extensions  
support already included in shoes would have been sufficient. What  
else is needed? Will the next shoes ship with bloopsaphone? It would  
be very nifty if it did. :)


Good luck with the bug fixings and the Hackety Hacking. I'm sure we're  
all looking forward to having a go with the new shoesian hackety  
hack. :)

Okay, thanks for sitting tight everybody. I'm back from ART  CODE
and, while I'm still working on Hackety Hack, I hope to return to
working on Shoes 3 in a week or so.

The idea is to put it out in a few weeks. The biggest part is that
we'll be moving to Ruby 1.9, VLC 1.9, and newer versions of Cairo
and Pango. Also, all of Tim Elliott's great work on Windows will be
merged. I've got some Vista fixes to work out as well.

The release after this one will focus on speed. Basically making the
retained graphics operate on an immediate surface. (A surface
living in its own thread.)

In Pittsburgh, I also had a chat with Seth Rasmussen about Shoes and
we kicked around an idea for having an extension library that would
make it a bit easier for people to bring in native controls (grids,
trees, systray, etc.) into Shoes without needing my approval. I
really like that idea and, yeah, could use some help with it.

Re: help with http post in shoes

[Jenna Fox]

Those very docs say And if you need to go beyond these, you can  
always break out Ruby's OpenURI class Does shoes hack open-uri to  
go via download, or is this some strange cyclical thing where the docs  
are advising that if download doesn't work we should be using  
Net::HTTP in a round about way?

I would stay away from Net::HTTP when using Shoes. It's a blocking
operation. Your whole app will stop until the request is done.

Use the `download` method, which can do HTTP in the background
and uses platform-specific code to work much, much faster.


 Shoes.app do
   download http://localhost:8080;, :method = POST,
:body = userName=userpassword=1 do |dl|
 para dl.response.body
   end
 end

You can read more in the Shoes manual.

Sure you could use a class var. Those are guaranteed to persist
throughout the life of the app. Or a constant.

Also, Shoes comes with SQLite3, data can be passed there.



Thank you!

No, I'll nix that recommendation, the HTTP stuff is fleshed -- I use
POST and PUT throughout Hackety Hack.
