AttributeError at /notify/notify/ 'UserNotifications' object has no attribute 'user'
I am trying to make a notifications app. I have a middle that collects info about the action the user should be notified about and in the view that handles the action it automatically creates an instance in the UserNotification model. This is all working. Now, if a user's post gets liked by another user, that actions needs to be displayed on the notifications page. However, I obviously don't want any one use to be able to see every notification that is being created on the site, but rather only the notifications that are created by their posts. I am running into an issue with the view and filtering the notifications based on the current user. More specifically, I am getting this error: AttributeError at /notify/notify/ 'UserNotifications' object has no attribute 'user' With traceback: Traceback (most recent call last): File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/core/handlers/exception.py", line 41, in inner response = get_response(request) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/core/handlers/base.py", line 187, in _get_response response = self.process_exception_by_middleware(e, request) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/core/handlers/base.py", line 185, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/views/generic/base.py", line 68, in view return self.dispatch(request, *args, **kwargs) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/contrib/auth/mixins.py", line 56, in dispatch return super(LoginRequiredMixin, self).dispatch(request, *args, **kwargs) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/views/generic/base.py", line 88, in dispatch return handler(request, *args, **kwargs) … -

How to initialize django objects automatically for the first time?
This is my first django application and I looked all over the place to find an answer, to no avail. I created my models and I know need to to initialize the values to one of the classes. I could do it using the admin page, one by one, but I want anyone using my application to be able to just load the application for the first time to have all the correct objects (and associated records in the database) to be created automatically.

I want to make a simple ticket system.

I can't open manage.py
On the command prompt, (Windows 10) I created a virtual environment, I then created a new project, I installed django in the virtual environment using pip. Then decided to run the command python manage.py runserver To run djangos web server, This returned with "...can't open file 'manage.py': [Errno 2] No such file or directory" I did see a similar question to this on this platform but it seems to only apply to those using linux. Where answers specify to use the ls command, which is not applicable on Windows command prompt. I have tried this multiple times but i just can't open manage.py -
Django creates migration files after each 'makemigrations' because of dictionary?
I've noticed strange things in my Django project. Each time I run python manage.py makemigrations command new migration file for my app called notifications is created. I did zero changes to the model, but the new migration file is created. I can run makemigrations command N number of times and N number of migration files will be created. The model looks as following: from django.db import models from django.db.models.fields import EmailField class EmailLog(models.Model): email = models.EmailField(max_length=70, null=False) subject = models.CharField(max_length=255, null=False) html_body = models.TextField(null=False) sent_choices = { ('OK', 'Sent'), ('KO', 'Not sent'), ('KK', 'Unexpected problems') } status = models.CharField(max_length=2, choices=sent_choices, null=False, default='KO') sent_log = models.TextField(null=True) sent_date = models.DateTimeField(auto_now_add=True, null=False) Each migration just swaps the position of sent_choices field. that's all! Is it because dictionaries in Python have random order? How do I avoid it? -

django + gunicorn + nginx: Browser refreshes toggling between PRE/POST dynamic content change
Below are the nginx.conf and gunicorn.start.sh files that I use for the Django application that I'm running (which, by the way, I didn't write). When I make any one-time change to dynamic content, then repeatedly refresh the browser, the rendered content switches/flaps variously between PRE and POST changes made. But it should just update once, and never again. The only thing that momentarily fixes the issue is restarting gunicorn: myapp$ sudo supervisorctl restart gunicorn But this only works until the next change to dynamic content. No good. I've tried numerous browsers, and it happens even when I clear their caches. Makes no difference. I also temporarily tried uWSGI instead of gunicorn (just to see), and the same issue occurs. A tail -f gunicorn.access.log during browser refreshes shows HTTP statuses that vary between 200 (content was downloaded) and 304 (you already have the content; redirecting you to your local cache). But dynamic content shouldn't be cached. Note that when running the application using the development server, like this: myapp$ python manage.py runserver --settings live 0.0.0.0:8080 the issue doesn't occur; but neither does this use nginx nor gunicorn. Any ideas? I've tried everything I know, but don't know what is causing this … -

Unresponsive django-bootstrap3-datetimepicker (not showing calendar)
As a beginner I often struggle with understanding the connections between Python-Django, html, javascript and css. The problem at hand is this: I'm trying to implement DateTimePicker widget from django-bootstrap3-datetimepicker-2. Since this library does not include js/css assets, I started by implementing datetimepicker without backend involvement just to see if I loaded all static files etc. correctly. Thus, I added this example to html template: <div class="container"> <div class="row"> <div class="col-sm-6"> <div class="form-group"> <div class="input-group date" id="datetimepicker1"> <input type="text" class="form-control"> <span class="input-group-addon"> <span class="glyphicon glyphicon-calendar"></span> </span> </div> </div> </div> <script type="text/javascript"> $(function () { $('#datetimepicker1').datetimepicker(); }); </script> </div> </div> Everything worked as intended, so I tried to implement datetimepicker as a widget from django forms: class FooForm(forms.Form): pick_a_date = forms.DateTimeField( widget=DateTimePicker(options={ "format": "YYYY-MM-DD", "pickTime": False} )) I also wanted to benefit from form wizard (namely SessionWizardView from formtools.wizard), so I output the above mentioned form into html like this: <form action="" method="post" role="form">{% csrf_token %} <table> {{ wizard.management_form }} {% if wizard.form.forms %} {{ wizard.form.management_form }} {% for form in wizard.form.forms %} {{ form }} {% endfor %} {% else %} {{ wizard.form }} {% endif %} </table> However, the widget is not responsive (the calendar window isn't showing, the … -

Creating / storing a form preview with Django forms and cart
I've never had to do this before and I'm wondering if I'm on the right track / this is the standard way to do something of this nature. I was going to use Django formtools FormPreview but it doesn' handle files (They can upload various images)... So, rolling my own solution or trying to. Currently I'm using a form wizard with model forms and everything validates / saves fine. I now want to add in a form preview, before purchasing the item they create with the form, and I've thought about doing the following: Save it to the database but mark it as not paid / inactive. On the form preview page grab the id (from pk in url) and display it. They have the option to go back and edit (update view) and / or pay. Using this route it's really easy to update and grab the data for viewing whether they wish to go back or forward. Similarly, if they add multiple items in their cart I can just display these items by grabbing the pk's from the DB rather than trying to handle a ton of session data. If they remove the item -> delete the row … -
Django UpdateView - get initial data from many-to-many field and add them when saving form
I'm using Django class based generic view. In my models.py I have a model called MyModel with many-to-many field called m2m. I have multiple groups of users they can edit the m2m field. Each group of users can only see and add their portion to the field - using get_form to set what they can see in the m2m field. The problem I'm having is that when one user enter his record it will delete the initial records in the m2m field. I need to somehow get the initial values from the m2m field save them and then add them to the new ones when the form is submitted. Here is my views.py: class MyModelUpdate(UpdateView): model = MyModel fields = ['m2m'] def get_initial(self): return initials def get_form(self, form_class=None): form = super(MyModelUpdate, self).get_form(form_class) form.fields["m2m"].queryset = DiffModel.objects.filter(user = self.request.user) return form def form_valid(self, form): form.instance.m2m.add( ??? add the initial values) return super(MyModelUpdate, self).form_valid(form) def get_success_url(self): ... -

How to start building a django website with postgres nginx and gunicorn on separate machines?

django domain setup and routing schema
Can anyone give me a short walkthrough (yes, I know that's asking a lot... I'm completely lost) of how to properly setup different domains using a single django project? Or... point me in the right direction / some insight to my questions below... I've searched around and looked at various app solutions, apache stuff, etc but still don't have a clear understanding. Specifically, each (main) app in my project is on a different domain. I have an app for news, job posts, etc and these would be on (name)news.io, (name)jobs.io, etc. In my settings.py file currently I'm using django-multiple-domains and have the MULTIURL_CONF set to point to each app based upon the domain name. As I understand it.... i can just set up the project on my domains using the same settings file since it will use this routing schema rather than the suggested route of multiple different settings file for each domain based upon the middleware that django-multiple-domains uses. Now, here's where I get confused on the URL routing.... In an app we typically include the urls inside the main urls.py file in the root app folder for our project to creating a routing schema for the entire site … -
