Laravel's dd() equivalent in django
Raise an exception. Assuming you've got debug on you'll see the exception message. It's crude but it's helped me in the past.
Just:
raise Exception("I want to know the value of this: " + myvariable_as_a_string)
Other answers & commenters ignored the crucial "and die" part of the dd() function, which prevents things like subsequent redirects.
Actually Django does not provide this specialized function. So in order to get rid of this problem, I made a custom dd()
type function and use this in all Django projects. Perhaps it can help someone.
Let's assume, we have a library folder named app_libs
and in that folder we have a library file named dump.py
. Like app_libs > dump.py:
from django.core import serializersfrom collections.abc import Iterablefrom django.db.models.query import QuerySetfrom django.core.exceptions import ObjectDoesNotExistdef dd(request, data=''): try: scheme = request.scheme server_name = request.META['SERVER_NAME'] server_port = request.META['SERVER_PORT'] remote_addr = request.META['REMOTE_ADDR'] user_agent = request.META['HTTP_USER_AGENT'] path = request.path method = request.method session = request.session cookies = request.COOKIES get_data = {} for key, value in request.GET.lists(): get_data[key] = value post_data = {} for key, value in request.POST.lists(): post_data[key] = value files = {} for key, value in request.FILES.lists(): files['name'] = request.FILES[key].name files['content_type'] = request.FILES[key].content_type files['size'] = request.FILES[key].size dump_data = '' query_data = '' executed_query = '' if data: if isinstance(data, Iterable): if isinstance(data, QuerySet): executed_query = data.query query_data = serializers.serialize('json', data) else: dump_data = dict(data) else: query_data = serializers.serialize('json', [data]) msg = f''' <html> <span style="color: red;"><b>Scheme</b></span> : <span style="color: blue;">{scheme}</span><br> <span style="color: red;"><b>Server Name</b></span> : <span style="color: blue;">{server_name}</span><br> <span style="color: red;"><b>Server Port</b></span> : <span style="color: blue;">{server_port}</span><br> <span style="color: red;"><b>Remote Address</b></span>: <span style="color: blue;">{remote_addr}</span><br> <span style="color: red;"><b>User Agent</b></span> : <span style="color: blue;">{user_agent}</span><br> <span style="color: red;"><b>Path</b></span> : <span style="color: blue;">{path}</span><br> <span style="color: red;"><b>Method</b></span> : <span style="color: blue;">{method}</span><br> <span style="color: red;"><b>Session</b></span> : <span style="color: blue;">{session}</span><br> <span style="color: red;"><b>Cookies</b></span> : <span style="color: blue;">{cookies}</span><br> <span style="color: red;"><b>Get Data</b></span> : <span style="color: blue;">{get_data}</span><br> <span style="color: red;"><b>Post Data</b></span> : <span style="color: blue;">{post_data}</span><br> <span style="color: red;"><b>Files</b></span> : <span style="color: blue;">{files}</span><br> <span style="color: red;"><b>Executed Query</b></span>: <span style="color: blue;"><br>{executed_query}</span><br> <span style="color: red;"><b>Query Data</b></span> : <span style="color: blue;"><br>{query_data}</span><br> <span style="color: red;"><b>Dump Data</b></span> : <span style="color: blue;"><br>{dump_data}</span><br> </html> ''' return msg except ObjectDoesNotExist: return False
when you need to use this function, just call it like this in any views.py:
from django.http import HttpResponsefrom django.shortcuts import renderfrom django.views import Viewfrom app_libs.dump import ddfrom .models import Productsclass ProductView(View): def get(self, request): data = {} data['page_title'] = 'products' data['products'] = Products.objects.get_all_product() template = 'products/collections.html' dump_data = dd(request, data['products']) return HttpResponse(dump_data) # return render(request, template, data)
that's it.
