Opinion on inheriting a previous model
I am looking at my code and see that that two models have mulitple similar fields. I was wondering if my ParentProfile model could inherit my User model in order to shorten the code and remove overlap. This is quite a beginner question and would like someone elses opinion on this matter. Thank you! models.py class User(AbstractBaseUser): email = models.EmailField(max_length=255, unique=True) first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) child_first_name = models.CharField(max_length=255) timestamp = models.DateTimeField(auto_now_add=True) student = models.BooleanField(default=False) parent = models.BooleanField(default=False) teacher = models.BooleanField(default=False) active = models.BooleanField(default=True) # can login staff = models.BooleanField(default=False) # staff user, not superuser admin = models.BooleanField(default=False) # superuser objects = UserManager() # takes email as username | removes email USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] def __str__(self): return self.email def has_perm(self, perm, onj=None): "Does the user have a specific permission?" return True def has_module_perms(self, app_label): "Does the user have permissions to view the app 'app_label'?" return True @property def is_staff(self): return self.staff @property def is_admin(self): return self.admin @property def is_active(self): return self.active class ParentProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) email = models.EmailField(max_length=255, unique=True) first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) child_first_name = models.CharField(max_length=255) timestamp = models.DateTimeField(auto_now_add=True) student = models.BooleanField(default=False) parent = models.BooleanField(default=False) teacher = models.BooleanField(default=False) active = models.BooleanField(default=True) … -

Wagtail Custom API
I am trying to use Wagtail API to feed my D3 plugin. I want to sent a JSON output of my nested ClusterableModels. I have created 2 sets of Snippets in my models.py. One is graph containing the nodes and the other for the nested nodes: @register_snippet class Graph(ClusterableModel): name = models.CharField(max_length=255) panels = [ FieldPanel('name'), InlinePanel('graph_nodes', label='Select Nodes'), ] def __str__(self): return '{}'.format(self.name) class Meta: verbose_name = 'Graph' verbose_name_plural = 'Graphs' @register_snippet class Node(ClusterableModel, Orderable): name = models.CharField(max_length=255) body = models.TextField(blank=True, null=True) panels = [ FieldPanel('name'), FieldPanel('body'), InlinePanel('node_to_node' , label='connect to ...'), ] def __str__(self): return '{} ({} links)'.format(self.name, self.node_to_node.count()) class NodeRelations(Orderable, ClusterableModel): parent = ParentalKey(Node, related_name='node_to_node', null=True, blank=True) node = models.ForeignKey(Node, related_name="+", on_delete=models.CASCADE, blank=True, null=True) panels = [ SnippetChooserPanel('node'), ] class GraphNodeRelations(Orderable): parent = ParentalKey(Graph, related_name='graph_nodes', null=True, blank=True) node = models.ForeignKey(Node, related_name='+', on_delete=models.SET_NULL, blank=True, null=True) panels = [ SnippetChooserPanel('node'), ] The problem is that Wagtail does not have a standard API for ClusterableModel or Snippets. However, it offer custom endpoints using 'BaseAPIEndpoint'. I was successful finding the built-in 'PagesAPIEndpoint' code that give insight about the process yet I struggle to come up with a working code that simply fetchs the requested graph(my graph) and its nested children(Nodes) -
Variable Queryset filter by using a string as input
im working on creating a variable queryset by using a string and im not reaching the solution. This is my method output = "entradaid__in=[" for x in carrito_entradas: output+=x+"," temp=len(output) output = output[:temp - 1] output += "]" peliculas = Pelicula.objects.filter(output) What I want is create a queryset of "Peliculas" that can filter more than one value. My intention is this: output=entradaid__in=[1,2,5]. Pelicula.objects.filter(entradaid__in=[1,2,5]) Is there a way where I can do this? -
Wrapping content with the same tags multiple times in Django templates
Given a base.html file containing the following: <div class="foo some-content"> ... </div> <div class="bar some-content"> ... </div> I would like to wrap each of the .some-content divs to achieve a nested structure when using base.html in certain places: <div class="row"> <div class="foo some-content"> ... </div> </div> <div class="row"> <div class="bar some-content"> ... </div> </div> I tried extending base.html to wrap the divs with a .row div: {% extends base.html %} {% block wrapper %} <div class "row"> {{ block.super }} </div> {% endblock %} But that didn't work as I got a TemplateSyntaxError for using block wrapper twice in base.html: # Throws TemplateSyntaxError {% block wrapper %} <div class="foo some-content"> ... </div> {% endblock %} {% block wrapper %} <div class="bar some-content"> ... </div> {% endblock %} I realize that I could break up the .some-content divs in to their own files, and reuse those in other places, but I would prefer another route. I also looked at Django template macros as suggested in this SO post, but I think middleware will be overkill in this situation. Is there any way I can extend or reuse my current base.html file so that the .some-content divs are sometimes wrapped in a … -

Django (DRF) Boolean Field missing in JSON
I'm writing a rather simple REST API using Django REST Framework. I am trying to add a boolean field to my model that would show if it is publicly accessible or not. In my models.py, my model looks like this: class BlogPost(models.Model): title = models.CharField(max_length=20, default='', blank=False) description = models.CharField(max_length=140, default='', blank=False) is_public = models.BooleanField(default=True, blank=False) Then in my serializers.py, my serializer for the model looks like this: class BlogPostSerializer(serializers.ModelSerializer): class Meta: model = BlogPost fields = ('title', 'description', 'is_public') However, when I create an instance of that model, and run my development server, the JSON only returns the title and the description. The is_public field is missing from the JSON. I've searched everywhere and can't find the reason for this odd problem. Any help would be much appreciated! -
Django multiple ModelForms in template
It would be highly appreciated if you could advise how template should be modified to scale modelforms as per code below. There are around 30 item models which are the same as parent model. Also, those modelform have to be saved to database separately so I assume there should be same amount of modelforms as there are models.

How to render page template from db?

How do I send an XML request by substituing values in the XML over SOAP?
I have an XML file in my template directory and this XML file has a few placeholders. I need to fill these placeholders with values from the database and calculations of other values (based on user input) and then send it over to a URL that will process this XML and return an XML response as well. This is how my XML file looks: my_file.xml <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:web="http://some_url.api.com" xmlns:web1="http://another_url.api.com"> <soapenv:Header> <web:AuthenticationToken> <web:licenseKey> string </web:licenseKey> <web:password> string </web:password> <web:username> string </web:username> </web:AuthenticationToken> </soapenv:Header> <soapenv:Body> <web:Shipping> <web:ShipRequest> <web1:dtnCtry> string </web1:dtnCtry> <web1:dtnZC> string </web1:dtnZC> <web1:details> <!--Zero or more repetitions:--> <web1:ShipRequestDetail> <web1:class> string </web1:class> <web1:wt> string </web1:wt> </web1:ShipRequestDetail> </web1:details> <web1:orgCtry> string </web1:orgCtry> <web1:orgZC> string </web1:orgZC> <web1:shipDateCCYYMMDD> string </web1:shipDateCCYYMMDD> <web1:shipID> string </web1:shipID> <web1:tarName> string </web1:tarName> </web:ShipRequest> </web:Shipping> </soapenv:Body> Each of those string values will have to be substituted with an actual database value. How do I go about this process? I have checked multiple forums, sites and multiple questions inside of SO and each one recommends a different approach. As a newbie, it is difficult for me to select one and it is extremely overwhelming. Could someone here please explain a process from scratch? Thanks! -

Django: create a model that has a set of values for each day of month

Is Django able to handle large number of requests?
I am developing a online market place and expect largish number of requests coming to the server. I have the option to choose between the following two: Django REST API Node.js I being a python fanboy had started developing in django, when I came across this blog, according to which the number of requests/sec that django is able to handle is abysmally low as compared to node.js stack. I have the following two main doubts: How can we increase the efficiency of django. I am aware about caching, having the media, django and database(maybe sharded) on separate servers. What other things can help to increase the request handling rate? Can incorporating those make it perform not this badly(as seen in the medium link above) as compared to node.js. Scaling of django. How much effort in comparison to node.js(more, less, significant more, significantly less) would it take scale the application, if the need arises in future. Thanks in advance. -

how can i make models unique in Django together
