Django - is it possible to filter a Queryset on a calculated field?
I have a database table which stores a users push notification time preferences, with local_push_time, and local_time_zone fields. I have an automated job that runs on our servers (in UTC time) every 10 minutes, and I’m looking to find users who are due to get a push notification in the next 10 minutes. Since we’re using Django, almost all of our data access takes places through the Django QuerySet API, which mostly does what we need. But for the use case described above, I’ve not seen a way that the QuerySet API could help here. What I’ve ended up doing is writing raw SQL, which looks something like this: SELECT * FROM user_push_preferences WHERE CAST(CAST(CAST(NOW() AS DATE) + CAST(local_push_time AS TIME) AS TIMESTAMP) AT TIME ZONE local_time_zone AS TIME) >= CAST(NOW() AS TIME) AND CAST(CAST(CAST(NOW() AS DATE) + CAST(local_push_time AS TIME) AS TIMESTAMP) AT TIME ZONE local_time_zone AS TIME) < CAST(NOW() AS TIME) + interval '10 minute’; We did consider storing a utc_push_time field on the DB table, but this was a non-starter, as it would need to update itself as the local_time_zone moves in or out of daylight savings time. So what I really want is to be able … -

Django, including one template in another results TemplateDoesNotExist at /
I'm using Django 3.0.4, Python, 3.8, VS Code and Windows 10. I want to include the post_list.html and post_new.html templates in my base.html file. I need to show them all on the main website. I just want to have one page comprising these templates. I think this would allow me to have an audio file playing consistently even when I submit a post - page would not reload I believe (but I haven't achieved this phase of project yet). I started achieving my goal by including my template post_new.html in the base.html. However, I spinned up the server, visited main site and I encountered a problem: TemplateDoesNotExist at / post_new.html Request Method: GET Request URL: http://127.0.0.1:8000/ Django Version: 3.0.4 Exception Type: TemplateDoesNotExist Exception Value: post_new.html Exception Location: C:\Users\marecki\Desktop\mareknasz_projekt\evviva_larte\venv\lib\site-packages\django\template\backends\django.py in reraise, line 84 Python Executable: C:\Users\marecki\Desktop\mareknasz_projekt\evviva_larte\venv\Scripts\python.exe Python Version: 3.8.0 Python Path: ['C:\\Users\\marecki\\Desktop\\mareknasz_projekt\\evviva_larte\\ewiwa', 'C:\\Program Files (x86)\\Python38-32\\python38.zip', 'C:\\Program Files (x86)\\Python38-32\\DLLs', 'C:\\Program Files (x86)\\Python38-32\\lib', 'C:\\Program Files (x86)\\Python38-32', 'C:\\Users\\marecki\\Desktop\\mareknasz_projekt\\evviva_larte\\venv', 'C:\\Users\\marecki\\Desktop\\mareknasz_projekt\\evviva_larte\\venv\\lib\\site-packages'] Server time: Wed, 8 Apr 2020 12:57:51 +0200 In settings.py I have included the following: BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) 'DIRS': [ os.path.join(BASE_DIR, 'templates') ], This is a base.html: {% load static %} {% include "post_new.html" %} <html> <head> <link rel="shortcut icon" href="{% static '/assets/favicon-32x32.png' %}" /> … -

Correct way of overriding URL viewflow (Reverse for 'detail' not found. 'detail' is not a valid view function or pattern name.)
im stuck with an error of : Reverse for 'detail' not found. 'detail' is not a valid view function or pattern name. when i tried to override the AssignTaskView View. The rationale for doing so is to allow my user to reassign Tasks to others without having to generate a seperate task to do so as well as to put in my custom forms for displaying the lsit of users to choose from. I have most of my inspirations from this particular post : Overwrite django view with custom context (Django 1.11, Viewflow) And here is my code: url.py It actually allows me to override and display my own form . path('pipeline/<process_pk>/documents/<task_pk>/assign/', OverrideTaskView.as_view(), { 'flow_class': Pipeline, 'flow_task': Pipeline.documents }), the issue lies here : views.py class OverrideTaskView(AssignTaskView,FormView): form_class=AssignForm def get_form_kwargs(self): kwargs = super(OverrideTaskView, self).get_form_kwargs() kwargs.update({'id': self.request.user}) return kwargs def get_context_data(self, **kwargs): context = super(AssignTaskView, self).get_context_data(**kwargs) context['activation'] = self.activation return context def form_valid(self, form): if '_assign' or '_continue' in request.POST: form.save(commit=False) assigned = form.cleaned_data.get('user') self.activation.assign(assigned) self.success(_('Task {task} has been assigned')) return HttpResponseRedirect(self.get_success_url()) else: return self.get(request, *args, **kwargs) I suspect it has something to do with the get_success_url ?

Do you know Alternatives to PHPliteadmin or PHPAdminer? Create one with Django?
I'm struggling to find an Open Source Webinterface in Order to have a variety of options to interact with SQlite3 database. What I'm looking for is a webinterface, where I can have tables linked with keys to each other and a possibility to put SQL queries, that can output what I'm searching for in the tables. When it shows all the data it found with the queries I want to edit those right when it shows them to me - not by going back and searching the table where it is inside. I hope you understand what I'm trying to search. Phpliteadmin and adminer don't support it, do you know an alternative or a django example that goes in that direction that I'm searching for? Maybe I could program the code so that it could fullfill the needs. I thank you very much for your help, I really appreacciate it! -

Here is an example model: class SomeModel(models.Model): # Here I will put some model attributes class Meta: permissions = ( ('some_permission', 'Can do some job'), ) Until now I am not confused yet. However, when I am trying to write the view, I am confused. I read some Stack Overflow questions and also the django documentation, but I did not understand well because they are writing something like this: class MyView(PermissionRequiredMixin, View) permission_required = ('polls.can_open', 'polls.can_edit') I tried to figure out what to write in my case, and I ended up in writing this: class SomeView(PermissionRequiredMixin, View): permission_denied_message = 'You don\'t have permission' permission_required = 'app_name.some_permission' What made me in doubt is that PyCharm did not auto-complete when I wrote the last line which is: permission_required = 'app_name.some_permission'. Also, I am not sure whether django will know which permission that I am talking about here. Did I understand how to do the job? or I am wrong? Should I write it like this: permission_required = 'app_name.SomeModel.some_permission'?
