Zabo create_user api
I'm trying to use the Zabo rest api for create user which can be found here: https://zabo.com/docs/?shell#create-a-user The api says to do this (copied and pasted here): curl "https://api.zabo.com/sandbox-v1/users" \ -X POST \ -H "X-Zabo-Key: adminApiKey-established-in-dash" \ -H "X-Zabo-Sig: signature-of-request-using-paired-secret-key" \ -H "X-Zabo-Timestamp: 1420069800000" \ -d '{ "id": "8b0a037f-67cb-44b7-ac2a-18e7a54561a8", "token": "zabosession-abcdef1234567890" }' I'm doing this in Python: def _get_signature_and_time(self, url, body, secret): mtime = round(time.time() * 1000) json_body = json.dumps(body) logger.info(mtime) logger.info(url) logger.info(secret) logger.info(json_body) text_value = "%d%s%s" % (mtime, url, json_body) logger.info(text_value) signature = hmac.new(bytes(secret, "UTF-8"), bytes(text_value, "UTF-8"), hashlib.sha256).hexdigest() return signature, mtime I keep getting a different signature than what their library (currently only available in nodeJS) is providing.

django for professionals book
I am currently on page 241 of the "Django for professionals" book.

Django Model Field Inline
In Django, you can use inline to make new instances of models by just clicking the add instance button on the bottom of the admin site. Is there a way to do this for a model field inside a model. For example, if you were cataloging a book and you want to capture all the chapters in each books name. Every book has a different number of chapters so you could not just do chapter1 = CharField(max_length = 200) chapter2 = CharField(max_length = 200) and so on. Like the picture below but not for model instances for model fields. -

Adding Nodejs to Django
I hope this post doesn't get removed for not being specific enough but I am trying to get regular barcodes read in a Django project and I am not finding a way to do it that matches my ability to implement it in the time that I have allotted. I see a lot of ways to do it using Nodejs and I really don't want to add another framework for just this one function but I am not seeing any other way to do it that has good browser support. My specific question is: is this a bad route to take or is it common practice to add another framework like this? -

Is it better to make separate django models, or add various foreign keys to one model?
I have a model to capture comments from a user, DocumentComment. The comments are tied to a particular document in the database, and created/edited/displayed on the page that displays that particular document: class DocumentComment(Model): """ Captures a user's comment about a document """ document_id = models.ForeignKey(Document, on_delete=models.CASCADE, verbose_name="document file name", related_name='document') user = models.ForeignKey(User, on_delete=models.CASCADE) comment = models.TextField('comment', blank=True) moderated = models.BooleanField(default=False) added_to_description = models.BooleanField(default=False) marked_for_deletion = models.BooleanField(default=False) created = models.DateTimeField(auto_now_add=True, editable=False, verbose_name="date created") updated = models.DateTimeField(auto_now=True, editable=False, verbose_name="last update") I now find I need to record comments based on other objects displayed on different pages in the site, e.g. albums (collections of document) is a page and word clouds (derived from all the words in various documents) is another page. Since these new comments are not tied to one document, but a collection of documents, I don't think they should be added to the DocumentComment model for every document_id in the collection. I wouldn't necessarily want the comments on a collection to be displayed on the page with one of the documents in that collection. Which approach is better (django-yy or pythonic or idiomatic or by whatever standard you choose): create separate models as above for each display object … -
