LOGIN_REDIRECT_URL to a specific View
Is there a way to specify a view in the LOGIN_REDIRECT_URL setting in settings.py? I am using django-allauth for registration and logging in. What i am trying to do is as follows: When the user is logged in, determine if the user is_user_A or is_user_B (is_user_A being default). If is_user_A -> redirect to is_user_A-dashboard.html If is_user_B -> redirect to is_user_B-dashboard.html My code is as follows: views.py def logged_in(request): if request.user.is_user_A: return render(request, "is_user_A-dashboard.html") if request.user.is_user_B: return render(request, "is_user_B-dashboard.html") settings.py LOGIN_REDIRECT_URL = '/' -

Programmatically launch a new website
I'm building a new Saas platform using Django, which will help businesses from a certain industry create their own e-commerce stores. Still have to choose between Heroku or AWS for hosting (open to other suggestions). The app will create the module for serving content through a web server. The part where I am stuck is after a user has uploaded their products, the web app is generated and the IP address with their DNS provider, how can I launch a website with code? Which Paas platforms allow for it? My apologies if this is not a very smart question to ask. -

How Do I Make A Django (Python) Project Use Only A Specific Interpreter?
I am trying to set up a Django project. Initially I had Python 3.5 installed for a data analysis project I worked on. So while Python 3.5 works in tandem with matplot, pandas, scipy etc, the Django tutorial recommended I use 2.7 for the Django project as MySQL support for Python 3.5 is only third-party. I am also required to download Microsoft Visual C++ 14.0 anytime I try pip install mysqlclient for 3.5. Unfortunately my internet connection/data is quite limited. The thing is, I have installed 2.7 and it resides in C:\Python27. Python 3.5 is installed in C:\Users\XXXX\AppData\Local\Programs\Python\Python35-32 I have created a project directory - django-admin startproject myproject. I have installed the MySQLDb package to C:\Python27. But each time I attempt from command promptC:\Users\XXXX\Documents\WebDev\seedstars> python manage.py runserver, I get this error message: Traceback (most recent call last): File "C:\Users\XXXX\AppData\Local\Programs\Python\Python35-32\lib\site- packages\django\db\backends\mysql\base.py", line 25, in <module> import MySQLdb as Database ImportError: No module named 'MySQLdb' I tried setting my Python interpreter in PyCharm to Python 2.7. Each time I do this - python manage.py runserver, it reverts back to the error above. Please, how do I set this Django project to only "listen" to the Python2.7 interpreter, at cmd? Thanks. -
Moving a django instal to a new server and I'm getting a 403 error
I'm trying to move a django installation to a new server with a different IP.

Django1.8 and Python 2.7: Radio button stores the first option whatever is my choice

Substract 2 time fields in a ModelForm
I am trying to build a small logBook for pilots, where a user inputs the take off time and the time he landed and the forms returns below that duration in the form: 02:34 hrs i.e 2 hours 34 minutes. on the models.py side this is how I set it up: take_off_time = models.TimeField() land_time = models.TimeField() tot_time_field = models.DurationField() model.Duration doesn't seem to be the answer here... On the forms.py so far I simply rendered the model. So the questions are: What could i use instead of durationField? How can I take the inputs and render the calculation? I have tried in the models.py a simple: def get_total_time(self): self.tot_time_field = self.land_time - self.take_off_time return self.tot_time and then use tot_time in the form but I am not sure this is correct. -

How to redirect from one view to another?
I have an x view that redirects me to some_name.html page. This view needs to create a class that it is importing from other python file. This view calls a specific function (algorithm) that has some logic in it. lets say this func return a dictionary. I want that view 'x' will redirect me to negotioate.html page with this dynamic return dictionary. When the user gets the output he should choose from 3 options and basically trigger the algorithm again. Meaning, I want in each of those trigger to display the user the algo output but without reidrecting me to other page, but refreshing the current one. -
Django - Multiple users assign different names for the same object
I'm trying to add attribute to relationship. I have a model Scheduler, Product and User. There are multiple Scheduler objects in database. Each can have multiple products. And each product has some of those schedulers. The user can choose which scheduler to use with a product. I want user to be able to name this scheduler (note that one scheduler can be used by many products by multiple users). Use case: User creates a product and choose from allowed schedulers. When they choose the scheduler they can assign some name to this scheduler. For user1, the scheduler with id=5 has name='My scheduler - everyday' For user2, the same scheduler (id=5) has name='Everyday schedule' class Product(models.Model): user = models.ForeignKey(User, null=False, blank=False) scheduler = models.ForeignKey('Scheduler', null=True, blank=True, related_name='products') class Scheduler(models.Model): weekhours = models.ManyToManyField('WeekHour', related_name='schedulers') identificator = models.TextField(null=True,blank=True) Is it possible to do that in some simple way? -
