Title: Tutorial: creating a bitcoin instawallet clone with python and django
Post by: kangasbros on December 25, 2011, 05:44:35 PM
Hi, I wrote this little tutorial for those who are interested in developing bitcoin web apps with python/django
http://blog.kangasbros.fi/?p=85
This is my first time writing something like this, feedback welcome!
Edit: the github repo: https://github.com/kangasbros/django-bitcoin-instawallet

Hi, thanks for making this, I might use it at some point. I only skimmed the first 1/3 of it and have some suggestions: 1.) when showing stuff the user has to enter in some shell (there might be different shells involved at some point, like bash and python shell), replicate the prompt, something like this: #> pip install django
#> django-admin.py startproject instawallet
#> cd instawallet
that way, the user (always assume he knows nothing) always knows that this is commands he is supposed to enter and in which shell they go. Another upside to this is that you can also replicate the shells answer in cases where this might be reassuring, like so: #> bitcoind stop
bitcoind stopping
2.) When telling the reader to edit/create some file, you should always state the name of the file clearly. You could also emphasize the filename in the pretext. Here is an example that leaves me uncertain about what the file should be named and where it goes: We set up the sqlite database as a file “dev.db”. After that we add “django_bitcoin” and “wallets” to INSTALLED_APPS so that django can find our apps. Also we specify a templates directory. Create a folder “templates” inside the project root.
You're telling the reader to create a folder and then give him some text he should put in a file... which file? db.env? Where does it go? In the templates folder? This is not clear, always be clear on this. This problem is seen in many tutorials: the author makes some assumptions about the users just _knowing_ where some config directives or newly created files should go. It might be crystal-clear to the author (who is an expert), but keep in mind that all the stuff you write is probably new to the reader, so he is very uncertain about things and it helps to reassure him by stating the obvious. Other than that your tutorial seems great! I will give you more feedback once I actually go through with it. Thanks!

You have to {% load currency_conversions %} in your template, and check that django_bitcoin is installed.
Otherwise, thanks for the feedback, I try to improve the tutorial later today.

rpcallowip=* right? i've done that, still got the same error report.

rpcallowip=* right? i've done that, still got the same error report. That error means that you are not getting proper results from the bitcoind. Try checking the connection string in settings. Also with django you can go to console and execute "python manage.py shell" or with django-extensions installed "python manage.py shell_plus" That way you can test on command line what goes wrong. Just try creating a bitcoin wallet object, and getting the receiving address.

Maybe i should check 0.4, and try your suggestions. thanks.

BITCOIND_CONNECTION_STRING = "http://login:password@domain:8332" I think that changing the version doesn't necessarily help that much...

As you can see from the stack trace, python fails retrieving proper JSON from the server. I would advise trying to contact the server via command line python shell. Unfortunately that is the best advice I can give, the library is working fine for me. Other people have also been using it successfully. Have you checked the credentials you supplied in your bitcoind connection string?
BITCOIND_CONNECTION_STRING = "http://login:password@domain:8332"
I think that changing the version doesn't necessarily help that much...

Title: Re: Tutorial: creating a bitcoin instawallet clone with python and django
Post by: kangasbros on March 31, 2012, 02:33:43 PM
I am having this issue: https://github.com/kangasbros/django-bitcoin-instawallet/issues/1
'currency_conversions' is not a valid tag library
Note I know nothing about Django other than it seems to be one of those convention over specification languages that make me fringe :P
I'm trying it out for the sole purpose of using this library.
I'll paste some extra info for you to help me.
For some reason, django can't find the currency_conversions tag library, which should reside in django_bitcoin/templatetags/currency_conversions.py Check that django_bitcoin is properly installed (if you fetch it from git, it should be linked in a way so that django_bitcoin can be found by python, eg.: django-bitcoin/ <- git repo django_bitcoin <- links to django-bitcoin/django_bitcoin This isn't normal convention, but since I haven't yet released django_bitcoin 0.1, it can't be installed easier (or maybe can, I don't know much about python library packagin). Note I know nothing about Django other than it seems to be one of those convention over specification languages that make me fringe :P
Well, in my programming career I have done something bigger at least with following technologies: - Perl + CGI - PHP/MySQL/PostgreSQL etc - ASP.NET/C# - Ruby on Rails - Django So far, I have found django the best in the longer term. Of course it has it quirks, and not everything is always so easy, but to get shit done fast, while still keeping some kind of maintainability it is the best I have found so far. However this is a very debatable and subjective issue, of course :)

Post by: kangasbros on March 31, 2012, 02:35:12 PM
One small addition: actually in the tutorial the library is installed via setup.y, so that isn't the problem.... Hmm, have to think about it.
Title: Re: Tutorial: creating a bitcoin instawallet clone with python and django
Post by: wachtwoord on March 31, 2012, 05:22:53 PM
Thanks for the reply. It is true I have installed Django-bitcoin by pulling it from git and I have subsequently run the setup (sudo python setup.py install) which led to the directory structure you describe.
So the structure is (under Django_projects in my home directory):
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet$ ls
dev.db __init__.pyc settings.py templates wallets
django-bitcoin manage.py settings.py~ urls.py
__init__.py README.html settings.pyc urls.pyc
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet$ cd django-bitcoin/
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet/django-bitcoin$ ls
build django_bitcoin README.markdown setup.py
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet/django-bitcoin$ cd ..
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet$ cd wallets
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet/wallets$ ls
forms.py __init__.py models.py tests.py views.pyc
forms.pyc __init__.pyc models.pyc views.py
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet/wallets$ cd ..
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet$ cd templates/
ubuntu@ubuntu-VirtualBox:~/django_projects/instawallet/templates$ ls
instawallet.html instawallet.html~
Note that I have both cloned Django-bitcoin and django-bitcoin-instawallet from git (django-bitcoin-instawallet is renamed to instawallet) because I wanted to be sure I wasn't doing anything wrong myself. Of course I did make the necessary changes as described in the tutorial.
And as a final note on your set of languages. Anything is better than Perl! :P I have seen some garbage code in that language like you wouldn't believe (all supported with: but it's short, no?).
And as I said I really don't have enough experience with Django (hardly any) to judge it one way or another. I just really like explicitly specifying things for readability/maintainability :)

I just had an idea. Make an instawallet with a "Double or Nothing" button. Just a huge irresistible button that either doubles your balance or takes it all. Take a 1% or whatever fee by giving only 49.5% odds. Have to publish the max amount you can handle covering, maybe make it dynamic. If someone actually wants to do this I could probably put up some cash.

You really need to see a specialist about your gambling addiction. :)
Title: Feature request for django-python-instawallet
Post by: EskimoBob on April 22, 2012, 08:30:23 AM
In more serious note. Feature request #1 : Additional module for tipping aka "Bitcoin me" URI Generate a special URL, that can me used for only receiving a tip. I personally like the "Bitcoin me" URI idea: <a href="bitcoin:'bitcoin address here'?amount='amount here'&label='label here' ">bitcoin me!</a> (remove the " ' ") This starts your bitcoin client and you can complete the payment. Obviously, this can be redesigned/reversed so that your web based wallet is opened, authentication is requested and payment is made. Something like "Tip me from 'service name' " <a href="https://:wallet_serviceURL?amount='amount here'&label='Tip for the article' ">Bitcoin tip!</a> To add another layer of security, wallet service user must select/upload a "security image" for his/her account. This image is always displayed when he logs in to his account or starts to complete the tip payment. If someone has lured a user to a fake phishing site, image is missing or is not correct. User with a half a brain must notice this and stop. This actually requires a FR #3 Feature Request #3 Transactions or any changes to users account can not be completed without "PIN". PIN number is generated to user when account is first created.

You really need to see a specialist about your gambling addiction. :) Lol, I want to own it not to use it. Does that mean I'm in the clear or is that just worse? haha. worse, you're in denial.

I just had an idea. Make an instawallet with a "Double or Nothing" button. Just a huge irresistible button that either doubles your balance or takes it all. Take a 1% or whatever fee by giving only 49.5% odds. Have to publish the max amount you can handle covering, maybe make it dynamic. If someone actually wants to do this I could probably put up some cash.
Well, creating a gambling site with django_bitcoin is trivial. It could be of course an anonymous gambling site as well - just deposit your bitcoins to this address, and then you have gambling functionalities there. eg. "double or nothing" pseudocode: import random
from django_bitcoin import Wallet
def double_or_nothing(request, uuid):
main_wallet=Wallet.objects.get(id=1) # the main wallet, where the site's bitcoins are kept
user_wallet=Wallet.objects.get(uuid=uuid)
if random.random()<0.49:
main_wallet.send_to_wallet(user_wallet, user_wallet.total_balance())
else:
user_wallet.send_to_wallet(main_wallet, user_wallet.total_balance())
I just wrote the code directly here, so perhaps it doesn't work :D But anyway, the basic idea is very simple. Then of course, if you want to implement more complex gambling functionalities, it is easy. I'm not implementing this, since I think it doesn't fit well with wallet... But the library itself could be used as well for gambling sites, or almost anything.

I'm stuck with getting the QR code to display.
At the moment the image location is showing as http://10.1.1.14:8000/qrcode/mnooEeJ3GjR8ztUby9Ch9vgrp9BE6at6HV
I guess it needs to lookup the QR code through Google somehow but I have no idea.
Any ideas?

I have a question about the directory structure of django-bitcoin-instawallet and django_bitcoin.
I have django_bitcoin installed in the project folder, instawallet and the app wallets inside instawallet.
leo@ubuntu:~/django/instawallet/instawallet$ ls
dev.db __init__.pyc settings.pyc urls.pyc wsgi.pyc
django_bitcoin manage.py templates wallets
__init__.py settings.py urls.py wsgi.py
My question is can {% load currency_conversions %} from ~/django/instawallet/instawallet/templates/instawallet.html reach ~/django/instawallet/instawallet/django_bitcoin/templatetags/currency_conversions.py given the ~/django/instawallet/instawallet/settings.py file has 'django_bitcoin', in the INSTALLED_APPS?

Today at Bitcoin Hackathon (http://bitcoin-hackathon.com), I started a new project, and fixed some problems with django_bitcoin that only affect new users. These problems were mostly when you used easy_install or pip. I myself have always used cloned repository, so it didn't affect me.

About the qrcode-library, can you please point me in the right direction for this dependancy?
