I havent yet found a python way of doing this but here is an npm solution:
https://ethereum.stackexchange.com/questions/11166/how-to-generate-a-keystore-utc-file-from-the-raw-private-key
npm install ethereumjs-wallet
node
then:
var Wallet = require('ethereumjs-wallet');
var key = Buffer.from('<private key>', 'hex');
var wallet = Wallet.fromPrivateKey(key);
wallet.toV3String('<empty string or password');
we want to
A note in regards to blockchain.info:
https://github.com/primal100/pybitcointools/ appears to be the continuation of Vitalik Buterin’s abandoned https://github.com/vbuterin/pybitcointools.
Then:
from cryptos import *
words = 'word1 word2 word3 word4 word5 word6 word7 word8 word9 word10 word11 word12'
coin = Bitcoin()
private_wallet = coin.wallet(words)
xpub = private_wallet.keystore.xpub
# this is where you would start with an address calculation feature in an insecure environment like a web server
pub_keystore = keystore.from_xpub(xpub, coin, "p2pkh")
pub_wallet = wallet.HDWallet(pub_keystore)
print(pub_wallet.new_receiving_addresses(num=3))
This is based on http://support.divio.com/local-development/divio-shell/how-to-interact-with-your-local-projects-database
First, get rid of the old db:
docker ps
docker stop projectname_db_1
docker rm projectname_db_1
docker-compose up db
then import
cat db-dump.sql | docker exec -i projectname_db_1 psql -U postgres db
Django Admin is awesome but it lacks an important feature: Editing multiple items in batch. There are two django add-ons this functionality but both seem a bit out of date.
Here I would like to show an example of how simple batch editing can be added to django admin with minimal amount of code, taking advantage of django admin’s own get_form().
# admin.py
def batch_update_view(model_admin, request, queryset, field_name):
# removes all other fields from the django admin form for a model
def remove_fields(form):
for field in list(form.base_fields.keys()):
if not field == field_name:
del form.base_fields[field]
return form
# the return value is the form class, not the form class instance
form_class = remove_fields(model_admin.get_form(request))
if request.method == 'POST':
form = form_class()
# the view is already called via POST from the django admin changelist
# here we have to distinguish between just showing the intermediary view via post
# and actually confirming the bulk edits
# for this there is a hidden field 'form-post' in the html template
if 'form-post' in request.POST:
form = form_class(request.POST)
if form.is_valid():
for item in queryset.all():
setattr(item, field_name, form.cleaned_data[field_name])
item.save()
model_admin.message_user(request, "Changed offer on {} items".format(queryset.count()))
return HttpResponseRedirect(request.get_full_path())
return render(
request,
'admin/batch_editing_intermediary.html',
context={
'form': form,
'items': queryset,
'media': model_admin.media,
}
)
The template for the intermediary view could be made model agnostic by passing a list of (id, string) tuples to the template instead of item objects:
templates/admin/batch_editing_intermediary.html
{% extends "admin/base_site.html" %}
{% block extrahead %}{{ block.super }}
<script type="text/javascript" src="{% url 'admin:jsi18n' %}"></script>
{{ media }}
{% endblock %}
{% block content %}
<form action="" method="post">
{% csrf_token %}
<p>
{{ form }}
</p>
<ul>
{% for item in items %}
<li>
{{ item.id }} - {{ item.date }} - {{ item.who }} - {{ item.offer }} - {{ item.offer_work_type }}
</li>
{# this is required by Django Admin custom action framework #}
<input type="hidden" name="_selected_action" value="{{ item.pk }}"/>
{% endfor %}
</ul>
{# this is required by Django Admin custom action framework #}
<input type="hidden" name="action" value="{{ request.POST.action }}"/>
<input type="hidden" name="form-post" value="True"/>
<input type="submit" name="apply" value="Save"/>
</form>
{% endblock %}
