django project with private app
Currently I have a django project called Foobar. It consists of several apps that work together. Most of them are basic utilities for this one app(called star) that is the secret sauce. What I would like to do is is invite people to contribute to the project (to all it's utility apps) but not be able to see star. I wish star be closed sourced and developed only by the core team. How can I handle this? Should I move star to another repository on Github? Moreover, how do I deploy this project? Needless to say star needs all the utility apps to work. -
Django rest framework request data is always null
I just want to try simple Django rest framework code, I used APIVIEW and posted data through browser. CODE: class GetData(APIView): def post(self, request, format=None): if request.method == 'POST': item_id = request.data.get('item_id') return Response({"return": "OK ","item_id":item_id}) else: return Response({"return": "NOT OK "}) The above code should echo the item_id whatever i "POST"ed. but the result is always null. POST data: { "item_id" : "3456787"} result: {"item_id":null,"return" :"OK "} I don't understand where I went wrong. the above code works fine in my Loaclhost but does not work in production server. -

Second Django Logout Does Not Work
I am currently trying to get my Django login/logout to work correctly. However, I am having a problem where once I have logged in once, logged out once, and then logged in again to any other user, the logout function no longer works.

Django-Geopostion default value error
I'm trying to integrate location into my Django project. I have my model: class Post(models.Model): position = GeopositionField(default= Geoposition(40.00,73.88)) votes= models.IntegerField(default=0) date= models.DateTimeField(auto_now=False, auto_now_add=True) updated = models.DateTimeField(auto_now=True, auto_now_add=False) sound= models.FileField() I've tried leaving no value for position, but I can't make migrations without a default value. I've also gone ahead and removed all instances of the model from the admin. Even with what I have above (which I found from another person with the same issue) I'm getting a AttributeError: 'Geoposition' object has no attribute 'split' when I try to make the migration. Anyone have any pointers? -

Understanding how Models and Forms affect one another and database
I am creating form for users to input information too. I then want to save that information to a database and be able to extract information. I am having difficulty however when I try to create a drop down list and multiple selection list. For example say I define a model as in my models.py file as such: gi_category = models.CharField(max_length=4, choices=GI_NOGI) Where I have GI_NOGI specified as GI_NOGI = (('GI','GI'),('NOGI','NO-GI')) My forms.py looks something like this class RegisterForm(forms.ModelForm): weightclass = forms.ChoiceField(choices=WEIGHTCLASS, required=True,label='Weight Class') gi_category = forms.MultipleChoiceField(choices=GI_NOGI, label='Contest You Intend to Enter', widget=forms.CheckboxSelectMultiple(), required=True) class Meta: model = Register fields = ['name', 'age', 'birthdate', 'address', 'city', 'state', 'zip', 'phone', 'email'] labels = {'name':'Name', 'age':'Age on April 21', 'birthdate':'Birth date', 'address':'Address', 'city':'City', 'state':'State', 'zip':'Zip', 'phone':'Phone', 'email':'Email'} widgets = { 'birthdate':forms.TextInput(attrs={'placeholder': 'MM/DD/YYYY'}), 'phone':forms.TextInput(attrs={'placeholder': '(###)-###-####'})} Now I believe I am overwriting the gi_category and weightclass from models somehow because I cant access their respective values in the database. I don't know how to create a SelectMultiple any other way than I had I did(If this is problem any insight would be great. I am wondering what I am doing wrong? Also on a related note I want to have a database value for … -
Heroku Django ApplicationError: 'module' has no attribute 'TemporaryDirectory'

dyld: Library not loaded: @executable_path/../.Python
Awhile ago I had both Python2.7 and 3.5 installed on my Mac and was able to use them both successfully. Not too long ago I installed Anaconda and IPython. I have used those for a couple weeks for prototyping and in-console programming. After I went back to the regular Python for my Django and Flask projects, I discovered an unpleasant thing. Namely, whenever I try to run python or python3 I get the following error: dyld: Library not loaded: @executable_path/../.Python Referenced from: /Users/name/anaconda3/bin/python3 Reason: image not found Abort trap: 6 When I run conda I also get the same error. If I create a new virtual environment with virtualenv django-project, I am able to activate it, and it allows me to run Python 2.7 successfully. My question is the following. How can I fix python and python3 for the command line while also retaining the working Anaconda and IPython? How can I make sure that the virtual environments are able to carry Python3? -

How to set environment variables for your run configurations in PyCharm?
I have started to work in a Django project, and I would like to set some environment variables without having to set them manually or having a bash file to source. I would like to set the following variables: export DATABASE_URL=postgres://127.0.0.1:5432/my_db_name export DEBUG=1 # there are other variables, but they contain personal information Before you start downvoting, I have read this, but that does not solve what I want.
