Django determine if a item has been paid or not
i want to determine if an item has been brought or not by a user and if it's paid a diffrent content should get displayd but i dont know how to get these two models together (nooby). models.py class Post_Sell_Multiple(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(verbose_name="Post Title", max_length=40) content_preview = models.TextField(verbose_name="Post Content Preview", max_length=500) content = EncryptedTextField(verbose_name="Post Content", max_length=10000) ... class Post_Paid_Sell_Multiple(models.Model): paying_user = models.ForeignKey(User, on_delete=models.CASCADE) post_sell_multiple = models.ForeignKey(Post_Sell_Multiple, on_delete=models.CASCADE) status = StatusField(default='unpaid') STATUS = Choices('unpaid', 'paid') paid_date = models.DateField(auto_now_add=True, null=True) def publish(self): self.paid_date = timezone.now() self.save() class Meta: unique_together = ('paying_user', 'post_sell_multiple') ordering = ['-paid_date'] template.html <h1>{{ post.title }}</h1> {% if post.postcover %} <div> <img class="float-right postcover" src="/media/{{ post.postcover }}"> {% if post.post_paid_sell_multiple.STATUS == 'paid' %} <p>{{ post.content|safe|linebreaksbr }}</p> {% else %} <p>{{ post.content_preview|safe|linebreaksbr }}</p> {% endif %} what i want is first to get a relation between those two models and second if it's unpaid = display content_preview if it's paid = display content but it seems that im missing something in the relations because if i now create a post object nothing gets saved to the Post_Paid_Sell_Multiple model. thanks in advance -

Problems with django rest framework default field validation
I have the following problems for a nested model like this: def Post(models.Model) name = models.CharField(unique=True) content = models.TextField() def Comment(models.Model) post = models.ForeignKey(Post) content = models.CharField() I created default model serializers with all fields. Problems: The default model serializer does not work for nested models. I have to explicitly write create/update. This has been explained in the documentation, so nothing against it. Although I think choosing sane default can cater to 99% of use cases (and for the rest, behaviour can be customisable). I will try to take a shot at this. When I try to use json from existing post object, serializer is_valid() fails saying "unique constraint on name fails". But I wanted it to update and not create. Should is_valid not be create/update aware based on id being passed in json. When creating a new nested json with many comments, is_valid() fails saying that "post is empty". Of course I will not have post id in the json, as post creation is yet to happen. So is_valid becomes useless. Should is_valid not depend on if id is passed in json? Also, I can not use data/validated_data without having is_valid pass. Setting validators = [] also does not … -
Django ModelAdmin.get_formsets_with_inlines , to restrict data specific to the current user / owner
In order to restrict access of main model data to the current logged in user, I have used a queryset in admin.py similar to : @admin.register(MyModel) class MyModel(admin.ModelAdmin): def get_queryset(self, request): qs = super().get_queryset(request) if request.user.is.superuser: return qs return qs.filter(resource_owner=request.user) ... Owner is the name of the field that stores the current logged in user and this works like a charm ! However, this obviously does not work with inlines. I have searched the documentation and (could be wrong but) understand that one could use ModelAdmin.get_formsets_with_inlines to achieve this. Being a trainee , I am not certain how one would apply this formset to restrict access only to the owners inline model data just as the above queryset is being applied to the main model. The documentation is quoted below as : For example if you wanted to display a particular inline only in the change view, you could override get_formsets_with_inlines as documentedfollows: class MyModelAdmin(admin.ModelAdmin): inlines = [MyInline, SomeOtherInline] def get_formsets_with_inlines(self, request, obj=None): for inline in self.get_inline_instances(request, obj): # hide MyInline in the add view if not isinstance(inline, MyInline) or obj is not None: yield inline.get_formset(request, obj), inline I have tried to apply the above formset but am too inexperienced … -

Django 2: csrfmiddlewaretoken in url when hit back
I have a home page divided in two sections, where in one of them I have a form the user can fill and submit. The form submission should refresh only the div that contains that form. For that I'm using AJAX as I show below. Everything works fine except when I hit back after the form submission. The csrfmiddlewaretoken appears in the url as a parameter. Any idea if this is normal? How can I prevent it? The form: <form id="post-form"> {% csrf_token %} <fieldset> <legend>Facebook Login</legend> <div class="form-group"> <label for="InputName">Name</label> <input type="text" class="form-control" placeholder="name"> </div> <button type="submit" class="btn btn-primary">Submit</button> </fieldset> </form> AJAX script: <script src="{% static "vendor/jquery/jquery.min.js" %}"></script> <script src="{% static "vendor/bootstrap/js/bootstrap.bundle.min.js" %}"></script> <script src="https://cdn.jsdelivr.net/npm/js-cookie@2/src/js.cookie.min.js"></script> <script> var csrftoken = Cookies.get('csrftoken'); function csrfSafeMethod(method) { // these HTTP methods do not require CSRF protection return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } $.ajaxSetup({ beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } }); </script> <script type="text/javascript"> $('#post-form').on('submit',function(event){ event.preventDefault(); console.log("form submitted!"); // sanity check $.ajax({ type:'POST', url:'{% url 'test:test_url' %}', data:{ Name:$('#InputName').val(), }, success:function(context){ $('#post-form').html(context); } }); }); </script> -

Django log file created as root

Which process will be faster back-end work or sql query?
The scenario I was working on a search system which backend framework is Django 2 and Database is MySQL. The search system hit in the database with parameter and compile 4 table join query. Which make that search a little bit slower for lots of data I know. The query: itemViewCategory = Item.objects.raw("select *, company.slug as companySlug, company.name as companyName, field.id as fieldId, field.name as fieldName, category.name as categoryName from company inner join category on company.business_type = category.id inner join category_field on category_field.category_id = category.id inner join custom_field as field on category_field.field_id = field.id where category.id = (select id from category where slug= %s) and field.name LIKE %s order by company.name", [slug,product]) Now I need to count that query result for different work. I can do that 2 way Use a for loop to count that data. I can Do another query for count that data. Now my question is which process will be faster? I do some google and become too much confused. -
Object of type QuerySet is not JSON serializable
I have these list objects that are callable by name. They have number values that users can input. how would I turn each of those lists to form that chart js can render? I tried with this: Django Queryset to dict for use in json but could not get it working. Getting "Object of type QuerySet is not JSON serializable". Chart js would need to have own line for each of those list and show the values in those lines. This is how far I got with the link in views: First I get all of users lists: user_lists = List.objects.filter(user=user) Then I get number values for each list list_data = {} for list in user_lists: list_data[list.name] = DataItem.objects.filter(list=list) Here is where I get stuck when I should convert these lists to something that chart.js can understand.. list_data_json = json.dumps(list_data, cls=DjangoJSONEncoder) btw am I in the right tracks to put this conversion to views, right? or does it belong somewhere else?

Django Rest framework Serializer necessary?
I had one business requirement to be implemented lately which required me to just fetch the data and render the response. So some API endpoint would return a response as: [{"id" :1,"name":"first"} ,{"id" :2,"name":"second":}] Can I just render this data by constructing a list of dictionaries which can be populated with various ORM queries instead of rendering the response through a serializer? Would it be an efficient solution in case I won't be using this serializer ever for POST request? -

Django : Use decorator 'user_passes_test' using LDAP group witout django DB
I want to use LDAP AUTH for django. For the moment I have also a django Model Backend where are all my users and theirs groups. In my code, an user passes a test in order to access to application. This operation check if the group to allow is in the user information. But now I wanted to stop using Model Authentication and use only LDAP AUTH... How can I manage to use the same function to allow access, with LDAP groups without creating an user in the Model?
