Django: redirect to view with parameters
I am using Django authentication. Whenever a user logs in, I want to redirect him to /profile/user_id, being user_id a number. I can get the value of user_id by request.user.profile.id.

Django - CreateView /Modelform wont save Many to Many
I'm having trouble with the following problem: I am working on simple database app where users can add both Objects and create 'Notes' for these objects. These notes in turn can have tags (a many to many) which can be used to filter them. However, when I am creating a new Note, the accompanying tags are not saved in the form. Here is the code I used for the Noteform class NoteForm(ModelForm): class Meta: model = Note fields = ['content', 'tags'] def __init__(self, *args, **kwargs): self.model = kwargs.pop('model') self.app = kwargs.pop('app') self.key = kwargs.pop('model_pk') self.model_object = apps.get_model(self.app, self.model) self.linked_object = self.model_object.objects.get(pk=self.key) super(NoteForm, self).__init__(*args, **kwargs) def save(self, commit=True): note = super(NoteForm, self).save(commit=False) note.content_object = self.linked_object if commit: note.save() return note And here is the accompanying view: class BaseNoteCreateView(LoginRequiredMixin, CreateView): login_url = '/login/' form_class = NoteForm def get_form_kwargs(self): kwargs = super(BaseNoteCreateView, self).get_form_kwargs() kwargs['model'] = self.kwargs['model'] kwargs['app'] = self.kwargs['app'] kwargs['model_pk'] = self.kwargs['model_pk'] return kwargs def form_valid(self, form): form.instance.user = self.request.user return super().form_valid(form) Now I read that I might have to use the save_m2m() method. However, whenever I include it into the form or the view I run into the 'NoteForm' object has no attribute 'save_m2m' error. When I print the 'kwargs' in the … -
Django Model Form does not display Image field properly and does not Post it
The look of the File Upload for the picture in the Form is not OK as the button is inside the field. While it shows in the form as uploaded, it won't post. When I look in the firebug, I can see that the field for the File image is not being sent through with the other name fields, so the form never validates. Here is how it looks enter image description here Here is the definition in the Model. picture = models.ImageField(upload_to=user_directory_path) So when Django creates the Form it does it in that weird way for the File filed How should I then define the Field for File in the Model? Or where is the error lying? -
Comparing two variables in Jinja2?
I'm trying to print some values from my db onto a html page. Here's my jinja2 code: {% for Event in seller_event_disp %} {% for Items in seller_event_items_disp %} {% if Items.event_id == event_id %} {{ Items.item_name }} {% endif %} {% endfor %} {% endfor %} seller_event_disp and seller_event_items_disp are objects that I passed onto the html form via views. event_id is a variable which is also passed in a similar way. Individually, I have checked all of these and they do print properly in the html. For example, {{ event_id }} displays 1 on the page {% for Event in seller_event_disp %} {% Event %} {% endfor %} displays 1234, and similarly iterating through seller_event_items works as well. This is why I'm wondering if the == comparison is the issue. Indeed adding it anywhere to the code makes the rest of it after the addition stop working. What am I doing wrong here? Thanks! -

Elastic Beanstalk with Django: is there a way to run manage.py shell and have access to environment variables?
Similar question was asked here, however the solution does not give the shell access to the same environment as the deployment. If I inspect os.environ from within the shell, none of the environment variables appear. Is there a way to run the manage.py shell with the environment? PS: As a little side question, I know the mantra for EBS is to stop using eb ssh, but then how would you run one-off management scripts (that you don't want to run on every deploy)? -

How to update an ImageField in Django

Serving static files with nginx on multiple machines and hard drives
I have one project what will store large media content after it will be deployment. Project use Python, Django, also runned via Gunicorn and Supervisor. For static files I will use nginx. Basic setup I made by following this article, but I have an question, how can I store content more dynamicly. At the start I have one machine with 4 hard drives for 2Tb each, later will be buyed more, as well as the new machines (currently I have only one). Site located as site.com, nginx located at subdomain i.site.com and have 2 folders in a root: /static for storing css, js, svg, e.t.c. design elements and /media what will be stored media content. The problem is setup nginx to write media on each hard drives and each machine will be used. For the speed I need to write every new file in a different hard drive (like rotation/loop), for example I saving file1, it writed at machine1/hdd1, then I saving file2, it writed at machine1/hdd2... file4 at machine1/hdd4, file5 at machine2/hdd1 (currently as I mentioned I have only one machine, but will be more in a future).

Django queryset NOT INTERSECT for 2 models using postgres
I have a Django app, and I am trying to find out Employee that was NOT in Attendance 2017-12-05. I am trying to find out a queryset to accomplish this. The following are the details of the model, records, and the outcome I am trying to accomplish. I have 2 models: class Employee(models.Model): fullname = models.CharField(max_length=30, blank=False) class Attendance(models.Model): CHECKIN = 1 CHECKOUT = 2 ATTENDANCE_TYPE_CHOICES = ( (CHECKIN, "Check In"), (CHECKOUT, "Check Out"), ) employee = models.ForeignKey(Employee) activity_type = models.IntegerField(choices = ATTENDANCE_TYPE_CHOICES, default=CHECKIN) timestamp = models.DateTimeField(auto_now_add=True) Assuming I have the records below: Employee {"id":1, "employee":"michael jackson", "id":2, "fullname":"mariah carey", "id":3, "fullname":"taylor swift", "id":4, "fullname":"selena gomez"} Attendance {"id":1, "employee": 1,"activity_type": 1, timestamp: "2017-12-05 09:08", "id":2, "employee": 2,"activity_type": 1, timestamp: "2017-12-05 10:13", "id":3, "employee": 2,"activity_type": 2, timestamp: "2017-12-05 15:13", "id":4, "employee": 2,"activity_type": 1, timestamp: "2017-12-05 19:13", "id":5, "employee": 3,"activity_type": 1, timestamp: "2017-12-06 08:08"} This is the intended output I am trying to accomplish: For the date 2017-12-05, this employee was not in attendance (meaning there was no record in Attendance for 2017-12-05) {"id":3, "fullname":"taylor swift", "id":4, "fullname":"selena gomez"} What is the queryset to list out the employee that is not in attendance on a particular date 2017-12-05 ?
