Use same database for Django and Laravel
I'm using Django for backend, but for some reason, I want to use Laravel beside Django and share the database between them. so the same database for Django and Laravel. but the problem is that Django migrations are not equal to Laravel migrations so the database is different from ( for example constraints and indexes and some other options). Is this going to break backend if I use Django as the primary database and use Laravel as a secondary backend? If true, how I can use Django and Laravel in the same database? -
Django ModelForm not displaying
I'm trying to display a select box within a table in Django. Unfortunately, when I put the form within the HTML template it does not render although other elements do. forms.py: resultchoices = [ ('Not Started', 'Not Started'), ('Pass', 'Pass'), ('Issues', 'Issues'), ('N/A', 'N/A'), ] class checklistform(ModelForm): class Meta: model = checklist fields = "__all__" widgets = { 'INFO_001_result': Select(choices=resultchoices,), } models.py: class checklist(models.Model): resultchoices = [ ('Not Started','Not Started'), ('Pass', 'Pass'), ('Issues', 'Issues'), ('N/A', 'N/A'), ] INFO_001_result = models.CharField(choices=resultchoices,default='Not Started',null=False,max_length=11), INFO_001_remark = models.CharField(null=True,default='',max_length=400) Views.py: checklistform = checklistform # Create your views here. def checklist(request): context = { 'checklistform': checklistform, } return render(request, 'pages/Checklist.html',context ) HTML template: <td style="text-align:Center;background-color:#44546A;color:#000000;font-size:10px;width:108px;border: 1px solid #999999; " eth-cell="E5" >{{ checklistform.INFO_001_result }}</td> <td style="color:#000000;font-size:10px;width:88px;border: 1px solid #999999; " eth-cell="F5" >{{ checklistform.INFO_001_remark }}</td> </tr> Django doesn't give me any error it just fails to render that section within the template. -

Django custom context processor for sidebar navigation
I have an application that displays the parent object's title as a sidebar navigation label and its children under it as a list. To view this, this is my current setup: A project-level base template base.html with the sidebar and content layout. And in the base.html the sidebar navigation with lot of conditionals using {% if request.resolver_match.url_name == "<view-name>" %} to set what is active and display their related child objects as menu items under them. And then in the app templates I use {% extends "base.html" %}. But this feels a bit hacky and the sidebar content in the base.html is getting cluttered as I add views. Is there a simple pythonic/Django approach to solve this? I reckon context processors might be the right way to do this, but I am not sure how to do it without hardcoding the views. Something like, # do something and get the context object if is_parent(obj): child = get_related(obj) nav_categeory = obj.title nav_items = child.objects.all() # do something and return sidebar content html In other words, is there a functional DRY approach to conditionally populate the sidebar with navigational elements based on their context objects? -

Simply save time as UTC with Django
I get a timestamp (via an extern API). When I try to save that, it always is two hours earlier. I read some docs like Django Time zones, pytz and dateutil but I still don't understand how to tell Django that this specific time should not be converted to UTC because it already is UTC. It looks like this: t = '2020-05-29 08:47:39' # this is UTC MyModel( timestamp=t, … ).save() In the database it is stored as 2020-05-29 06:47:39. So it is shown on a template e. g. as 2020-05-29 08:47:39 whereas 2020-05-29 10:47:39 would be correct. settings.py TIME_ZONE = 'Europe/Berlin' USE_TZ = True -
