Is django-CMS and cookiecutter-django compatible?
I just tried to port my Django-CMS project into Django Cookiecutter (cookiecutter-django) in ordert to get it to run in Docker. It seems Django-CMS is using the default Django user model and Cookie-Cutter is using a custom model (from allauth?). I found this https://github.com/pydanny/cookiecutter-django/pull/248 thread and it suggests changing the order in which the apps are loaded but that doesn't cut the mustard. Are Django-CMS and Cookiecutter at odds with each other? -

Empty query returns all fields from database. Django
In the search form field, If I don't enter anything, but push on the button to search the query. The query returns every each field from the database. Company.objects.exclude(Q(name__isnull=True)).exclude(Q(name__exact='')) Somehow, doesn't help me. If I use them together or separate. The code in views.py is: class className(listView) model=Company template_name='name_of_the_template.html' def get_queryset(self): query=self.request.Get.get('q') query=query.replace('#',' ') //same for ?\/$%^+*()[] *tried to set exclude code here if query == ' ': object_list = Company.objects.filter(Q(name__icontains='None'))//sending to the empty object return object_list else: // *tried to set exclude code here object_list = Company.objects.filter(Q(name__icontains=query)) return object_list None of exclude code helps. I believe I do simple mistake somewhere... because code suppose to work, but somehow still. I just also tried to get rid off if else statement and use exclude statements for queries such as '', ' ' and null and after that filter for query... And now excluding queries for ' ' also doesn't work... Django doesn't tell me the exclude doesn't work, all works, except, it is like not in the code. -

How do I go about creating two objects that are tied to each other by a foreign key in one form/view in django?
So, I have a messaging component of an app I am creating. There is a Conversation object, which has a ManyToMany field to user. Then, there is the actual InsantMessage object, which has a sender field to user, textfield and another field called receiver that is a foreign key to my conversation object. Now what I am attempting to do is to create a link underneath another user's profile, and then pass their pk in that link to my view which will check to first see if their already exists a conversation object with request.user and the other user, and if so, will create a message object and then automatically pass in the Convo object pk for the foreign key field conversation in my Message object. Now, I think I have the basic understanding of how to do this, perhaps just using an if statement and a nested form. But, where I'm stuck in is, how do I get the conversation pk to automatically pass? And how would if the conversation object is being created, how can I get request.user/other user to be automatically put in the conversation object? Even if you don't want to write out my code, just … -

Form for updating model info is blank
I am trying to provide a form to update user info such as employment, location, birthday, interests. The form I tried to make will not show any of this info however, it just shows a submit button. user_info = models.UserInfo.objects.get(user=request.user) if request.method == 'POST': form = UserChangeForm(data=request.POST, instance=request.user) if form.is_valid(): form.save() return redirect('login:login_view') else: form = UserChangeForm(instance=request.user) context = { 'user_info' : user_info, 'form ' : form } return render(request, 'account.djhtml',context) I'm pretty sure I need to use user_info but Im not to sure how to do that.

How to import pickled python object into Django view.py file
This file runs perfectly well on its own: import pickle with open('model.obj', 'rb') as f: model = pickle.load(f) print(len(model)) But what I really want to do is to use model, which is a very large stored python dictionary, in my Django views.py file, like so: from django.shortcuts import render from modeler.load_model import model def page(request): return render(request, 'page.html', {'model':model}) However, when I try this, I get the error below: File "C:\Users\mmm\PycharmProjects\MyProject\modeler\load_model.py", line 3, in <module> with open('model.obj', 'rb') as f: FileNotFoundError: [Errno 2] No such file or directory: 'model.obj' I don't understand why, because if I run the first file directly it works fine - the only extra step here is importing it into views.py (I tried including the entire load_model.py code within views.py at first, but got this error, so then tried it in this separate file and it worked on its own, so obviously the issue is that I don't know how to correctly load/import my python model objects or files within Django.
