Remove none fileds from django templates
I created a django template with the following model Models.py class MaterialRequest(models.Model): owner = models.ForeignKey(Client, on_delete=models.CASCADE, related_name='allotment_sales') product1 = models.CharField(max_length=500,default=0,blank=True,null=True) product1_quantity = models.IntegerField(default=0,blank=True,null=True) product2 = models.CharField(max_length=500,default=0, blank=True,null=True) product2_quantity = models.IntegerField(default=0,blank=True,null=True) product3 = models.CharField(max_length=500,default=0, blank=True,null=True) product3_quantity = models.IntegerField(default=0,blank=True,null=True) product4 = models.CharField(max_length=500,default=0, blank=True,null=True) product4_quantity = models.IntegerField(default=0,blank=True,null=True) product5 = models.CharField(max_length=500,default=0, blank=True,null=True) product5_quantity = models.IntegerField(default=0,blank=True,null=True) product6 = models.CharField(max_length=500,default=0, blank=True,null=True) product6_quantity = models.IntegerField(default=0,blank=True,null=True) product7 = models.CharField(max_length=500,default=0, blank=True,null=True) product7_quantity = models.IntegerField(default=0,blank=True,null=True) product8 = models.CharField(max_length=500,default=0, blank=True,null=True) product8_quantity = models.IntegerField(default=0,blank=True,null=True) and I tried displaying this data on the template using this view def load_salesorder(request): so_id = request.GET.get('sales_order') s_o = MaterialRequest.objects.filter(pk=so_id) print("kits=========",s_o) return render(request, 'allotment_so.html', {'sales_order': s_o}) HTML <table class="table table-bordered"> <thead> <tr> <th>Product Short Codes</th> <th>Product Quantity</th> </tr> </thead> <tbody> <div class="table-container"> {% for i in sales_order %} <tr> <td class="align-middle">{{ i.product1 }}</td> <td class="align-middle">{{ i.product1_quantity }}</td> </tr> <tr> <td class="align-middle">{{ i.product2 }}</td> <td class="align-middle">{{ i.product2_quantity }}</td> </tr> <tr> <td class="align-middle">{{ i.product3 }}</td> <td class="align-middle">{{ i.product3_quantity }}</td> </tr> <tr> <td class="align-middle">{{ i.product4 }}</td> <td class="align-middle">{{ i.product4_quantity }}</td> </tr> <tr> <td class="align-middle">{{ i.product5 }}</td> <td class="align-middle">{{ i.product5_quantity }}</td> </tr> <tr> <td class="align-middle">{{ i.product6 }}</td> <td class="align-middle">{{ i.product6_quantity }}</td> </tr> <tr> <td class="align-middle">{{ i.product7 }}</td> <td class="align-middle">{{ i.product7_quantity }}</td> </tr> <tr> <td class="align-middle">{{ i.product8 }}</td> <td class="align-middle">{{ i.product8_quantity }}</td> </tr> … -
Customize schema of dango REST's framework for documentation
I am trying to document my APIs with the inbuilt REST documentation for APIs. I get it to render all my endpoints which is great. Now I want to customize the schema but I am unsure how to achieve that. I know that swagger has a schema generator but I would like to tweak what django already provides me. I am going this so far by doing: API_TITLE = "title" API_DESCRIPTION = "description" urlpatterns = [ path('docs/', include_docs_urls( title=API_TITLE, description=API_DESCRIPTION, permission_classes=[IsAdminUser]) ), that renders me all my endpoint. I add a screenshot. I would like for instance to fill the description for the thus far empty fields. I also would like to delete some stuff. I am not really clear on how to use schemas and how manipulate them and use them in django. I also can't find docs that are comprehensible to me. I know they are in .yml format but how can I get them and manipulate them? Or how can I build my own? Can someone help me with this? Thanks in advance, very much appreciated! I would like to delete for example the grey boxes and fill the blanks in the description. -
How do I return a list in a Django Annotation?
Right now I have the following, very slow but working code: crossover_list = {} for song_id in song_ids: crossover_set = list(dance_occurrences.filter( song_id=song_id).values_list('dance_name_id', flat=True).distinct()) crossover_list[song_id] = crossover_set It returns a dictionary where a song ID is used as a dictionary key, and a list of integer values is used as the value. The first three keys are the following: crossover_list = { 1:[38,37], 2:[38], .... } Does anyone here know of a succinct way to wrap this up into a single query? The data exists in a single table that has three columns where each song_id can be associated with multiple dance_ids. song_id | playlist_id | dance_id 1 1 38 1 2 37 2 1 38 Ideally, what I am trying to figure out how to return is: <QuerySet[{'song_id':1, [{'dance_id':38, 'dance_id':37}]}, {'song_id':2, [{'dance_id':38}]}]> Any ideas or help is appreciated. -

Create an event to update a table depending on entries from 2 other tables
Ok so I have these three tables created by my Django models in MariaDB: I want to create a daily event to update "LastInspected" in moorings_part whenever someone adds an inspection item. This should be the latest moorings_inspectionreport.Date available with an InspectionID_id which relates to the relevant moorings_inspection.PartID_id. It's really confusing me with not only the ordering by dates but trying to juggle 3 tables for this too. -

Django: Unable to load admin page and HTML page using TemplateView.as_view()
I used the django-twoscoops project template to setup a simple project (made some modifications to use django 2.2.5).

When I run the server, and connect to 127.0.0.1:8000/admin/ I get an error. However, if I go to 127.0.0.1:8000/polls/ the polls page loads OK. I also get an error if I try to go to 127.0.0.1:8000 (it complains base.html is not found and I don't understand why it is looking at a different path). I am not sure what I am doing wrong.
