Using djstripe for multiple subscriptions per customer
I've been using dj-stripe to handle customer subscriptions but I'm now exending the functionality so each customer can have a number of associated accounts, each of which requires a subscription and these accounts can be added at any time. I could invoice on a monthly basis depending on the number of active accounts but this could very complicated. From the documentation it seems it's possible to have multiple subscriptions but I'm not clear how to link them to the accounts and how to create a new plan/subscription when I add an Account. class MyCustomer(AbstractUser): multi_accounts = models.BooleanField(default=False) class Account(models.Model): customer = models.ForeignKey(MyCustomer) subscription_ends = models.DatetimeField() According to the documentation http://dj-stripe.readthedocs.io/en/latest/settings.html#djstripe-subscriber-model-settings-auth-user-model, I could add another model: class CustomerAccount(models.Model): customer = models.ForeignKey(MyCustomer) account = models.ForeignKey(Account) subscription_ends = models.DatetimeField() @property def email(self); return self.customer.email But I'm still not clear how I might use that as the example callback http://dj-stripe.readthedocs.io/en/latest/settings.html#djstripe-subscriber-model-request-callback-none assumes there is only one of this class of object per customer. Is there a way to do what I want with djstripe? -

Coverage.py warning: No data was collected. (no-data-collected)
I am trying to find the coverage using coverage module for a django project but gets "Coverage.py warning: No data was collected. (no-data-collected)". My project folder has src and tests folders. When I run coverage run -m pytest && coverage report It produces a report with 100% coverage with the list of files inside the tests folder. Whereas when I run coverage run --source=src -m pytest && coverage report it says Coverage.py warning: No data was collected. (no-data-collected) No data to report. When I try to give the source=src or include=src in the .coveragerc also the same warning occurs. The tests passes for all the above cases. I want the coverage of the src folder. Is it because I am missing some path setting? -
Django make changes in DB only for certain user / django-reversion revert version`s object only for a certain user
After a long time spent for googling without a big success I really need a help from someone who faced with this question earlier than me. I am using the django-reversion for storing an object changes, and my goal is to allow user to access a list of the object versions and select needed one, so the object will be changed for that version, however these changes shoud be visible only for that user. Other users should see the actual data of the object, until they also activate some other object version. But the django-reversion package works so that when you reverting the object to some version, this will affect original object in DB. Some possible solutions I was considering are django session and cookies, however it seems to be realy complicated for this use-case because the object has relations with other models. Please give me some directions, how it is possible to perform the expected behaviour. Or it is not possible to make this with django-reversion? Thanks in advance for any information! -

How can I alter the response coming from a delete request in Django Rest Framework?
I am creating an app which retrieves a list of students in the database and enabling the user to add and delete students.

Setting up setattr behavior of Django model without affecting instance initialization
I have a model called A. When b attribute is set of that model, I want to update that attribute like this: # Note that PGJSONField is a field that can store string or json. class A(models.Model): description = PGJSONField(blank=True, null=True) def __setattr__(self, key, val): if key == 'description': val = {'description': val} super(A, self).__setattr__(key, val) This causes a side effect. When I get model instance from DB. It set's up description key as dict event if it's not. >>> a = A.objects.first() >>> a.description ..: {"description": "lorem ipsum"} My expected bahavior is something like this: >>> a = A.objects.first() >>> a.description ..: "lorem ipsum" >>> a.description = "foo bar" >>> a.description = {"description": "foo bar"} I think I must by pass _setattr method when model is being fetched but I couldn't find a way to do it. Any suggestions? -
Application overhead design decision: store needed value on database row or find it dynamically in queryset
I'm developing a simple price tracker application. I'm a bit new to web application design and could use an experienced opinion here. My application pulls price points for hundreds of thousand of products per day by unique price SKU. For each SKU I want to be able to show: All time high price All time low price Average price When my API writes a new SKU price to the database I am able to figure out these three values and write them to the latest/current price row. Is this a better design decision than say using a Django Queryset in my View to query for and/or calculate and display them? -
Onclick Confirm add Checkbox Length
This should be really simple, but I can't get it to work and I'm an absolute beginner with Javascript. I looked at various threads here. I'm working with a django template, on a simple link. I want to add an onclick confirmation message such as 'Trash (14) Projects? Are you sure?' where 14 is the number of checkboxes ready to submit in a form. Right now I have. <button type="submit" class="actionbutton" name="delete" onclick="return confirm('Add projects to trash - Are you sure?')" >Remove / Add To Trash</button> Which of course doesn't have the number of projects to be deleted. I could add a script in the head to count the classes of checkboxes, but I want to know how I might execute javascript inside the confirm dialog itself? Such as... <button type="submit" class="actionbutton" name="delete" onclick="return confirm('Add ($(":checkbox:checked").length) to trash - Are you sure?')" >Remove / Add To Trash</button> Which doesn't work, probably because the ":checkbox:checked" gets escaped inside the onclick " ". Anyone point me in the right direction as to what is the 'usual' way to do this kind of thing... -
Django, How to route the traffic?
Contract an instance in gandi.net but I want to have several domains (vhost) in that same instance only I was satisfied with the support that is only possible redirecting the traffic with my python code, I have no idea how to do it. Thank you for contacting Gandi support. Python instances only have one vhost, named 'default'. If you'd like to host multiple Python website on a single instance, then you will need to route the traffic with your Python code, by using the 'host' header. host = self.headers.get('Host') https://doc.gandi.net/en/simple/python We are at your disposal should you need any further information. Best regards, if someone could clarify, how to do routing with django? -
Different css margins for mobile & desktop without multiple {% block content %} in Django template
I need to change the margin-left that is applied to my main {% block content %} in my base.html template (that contains my navbar and other common elements) based on if the viewer is using mobile or desktop. My current base.html is like: <div class="content container-fluid"> <div class="row"> <div class="col-md-8"> {% block content %} {% endblock %} </div> </div> </div> with a css file containing: .content { margin-left: 40px; } .content_mobile { margin-left: 10px; } Given that in other parts of my application I've accomplished this by using the following dedicated Bootstrap classes, my first thought was to do the same using something like: <div class=".visible-xs-block, hidden-xs"> <div class="content container-fluid"> <div class="row"> <div class="col-md-8"> <!-- This is hidden from mobile view --> {% block content %} {% endblock %} </div> </div> </div> </div> <div class=".visible-lg-block, hidden-lg .visible-md-block, hidden-md .visible-sm-block, hidden-sm"> <div class="content_mobile container-fluid"> <div class="row"> <div class="col-md-8"> <!-- This is hidden from all other views (including desktop) --> {% block content %} {% endblock %} </div> </div> </div> </div> But Django raises an exception because it can only render 1 {% block content %} per template!
