Django-Tezos
Project description
djTezos: Django-Tezos
Django-Tezos provides Django Models and uWSGI Spooler (djCall) integration with PyTezos.
Install djTezos
Install djtezos with pip then add djtezos to INSTALLED_APPS.
Run ./manage.py migrate to create tables for djtezos models.
You need a SECRET_KEY that is sufficiently long for AES.
Add Blockchains
Blockchain is the first model you have to manage, you can do it in the admin.
For any blockchain, you can choose a Python Provider Class, such as
djtezos.tezos.Provider or djtezos.fake.Provider for a mock that you can
use in tests.
Example:
tzlocal = Blockchain.objects.create(
name='tzlocal',
endpoint='http://tz:8732',
provider_class='djtezos.tezos.Provider',
is_active=True,
confirmation_blocks=1,
)
Run tzlocal with: docker run --rm --publish 8732:8732 yourlabs/tezos
Add to /etc/hosts: tz on line starting with 127.0.0.1
In gitlab-ci, add:
services:
- name: yourlabs/tezos
alias: tz
Create accounts
Create an account for a user:
account = user.account_set.create(blockchain=tzlocal)
Users can have as many accounts as you want.
Queue
Transactions are queued in the database with the Transaction model. You can emit 3 types of Transactions.
Deploy a smart contract
Create a Transaction with a contract_code to deploy a smart contract:
contract = Transaction.objects.create(
sender=account,
contract_code=mich,
contract_name='test',
args={'int': '1'},
state='deploy',
)
You may then retreive it through either of the Transaction model and the Contract proxy model.
Call a smart contract function
Call a smart contract function with a new Transaction:
call = Transaction.objects.create(
sender=account,
contract=contract,
function='replace',
args=[3],
state='deploy',
)
This calls the replace function with only one arg: an integer of 3.
A Call proxy model is also available to retrieve.
Execute a transfer
Create a transfer on the blockchain:
transfer = Transaction.objects.create(
sender=account,
receiver=account2,
amount=10000,
state='deploy',
)
