I build the comment system and when I click like in the first comment the like appears successfully but when I come to the next comment It returns the JSON response page {"a_c_like": true} instead of like appear and the like count in the span also didn't work (count).

AWS S3 bucket returns 403 error when referencing a static folder path in Django project
I'm hosting static files in an S3 bucket for a Django web app. All has been well so far using the Appwork custom admin template: https://uxpowered.com/products/appwork/v160/ The files are rendered fine locally but unable to render from the S3 bucket. I believe the error is the script below that is referencing a folder path instead of a direct file. <script> window.themeSettings = new ThemeSettings({ cssPath: "{% static 'app/admin/assets/vendor/css/rtl' %}", themesPath: "{% static 'app/admin/assets/vendor/css/rtl' %}", }); </script> How can I solve this problem?

I want to update a DIV that will contain an image from a database PostgreSQL, without refreshing the entire page. Backend Django
I want to update a DIV that will contain an image, initially there is no image, the image is in a database (the images table will have a field with the image path) PostgreSQL. Every time the database loads an image (it can be at any time) the DIV must be updated, showing the new image, without refreshing the HTML page. If the user wants to see the next image loaded in the database, he will only have to refresh the page. Thank you very much for your support. -

Getting keyerror when trying to populate HTML via Django Template
I'm making an HTML template that populates a table. The show in value refers to my model, Show, with values title, network, release, and desc. Here is the HTML: {% for key, value in request.session.items %} {% for show in value %} <tr> <td>{{ show.id }}</td> <td>{{ show.title }}</td> <td>{{ show.network }}</td> <td>{{ show.release }}</td> {% endfor %} My request.session looks like this in my views.py: def shows(request): request.session['object_list'] = Show.objects.all() print("*"*500) for key, value in request.session.items(): print(key, value) for show in value: print(show) print("*", show.id) print("*", show.title) print("*", show.network) print("*", show.release) print("*", show.desc) print("*"*500) return render(request, 'shows.html') I can get the code to print in shell, as seen above.

I'm assuming the problem comes from a miscommunication between my template and my views.py, but I can't figure it out. May or may not be important, but the KeyError isn't the only error code thrown.

Django form, cascading/dependant dropwdown not submitting correctly
I used this tutorial to have a dependant or cascading dropwdown, which lists the state, county and neighborhood while submitting a form. It displays correctly, but when I hit submit, the following error is listed: "Choose a valid option. That option is not available". It has two apps: posts and location, I'll post the posts.models, posts.forms and templates of posts, but not the view because it is a simple CreateView. About the location app, I'll post the models, views and templates I pass the info to the posts app. I did the location app apart because I want to also use it for searching these posts. ANY advice is extremely appreciated. As a side note: Estado = State, Municipio = County and Colonia = Neighborhood Here's my code: posts.models class PostRoom(models.Model): colonia = models.ForeignKey(Colonia, on_delete=models.SET_NULL, blank=True, null=True) municipio = models.ForeignKey(Municipio, on_delete=models.SET_NULL, blank=True, null=True) estado = models.ForeignKey(Estado, on_delete=models.SET_NULL, blank=True, null=True) class PostPerson(models.Model): colonia = models.ForeignKey(Colonia, on_delete=models.SET_NULL, blank=True, null=True) municipio = models.ForeignKey(Municipio, on_delete=models.SET_NULL, blank=True, null=True) estado = models.ForeignKey(Estado, on_delete=models.SET_NULL, blank=True, null=True) posts.forms class PostPersonForm(forms.ModelForm): class Meta: model = PostPerson fields = ('colonia', 'municipio', 'estado') def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['municipio'].queryset = Municipio.objects.none() self.fields['colonia'].queryset = Colonia.objects.none() class PostRoomForm(forms.ModelForm): class Meta: model = … -
Django Toggle Div on Search Query
I have a basic search query to find customers on one of my forms in my Django project. It returns results from the database in an HTML table. The query is executed by clicking the search button. I want to hide the div encapsulating the table when the query has not been executed. Because the JS function is executed when the search button is clicked, the table only shows momentarily until the page reloads. What is the convention for displaying a div after a query is executed, without having a constant toggle button? views.py @method_decorator(login_required, name='dispatch') class CustomerResultsView(ListView): model = CustomerName template_name = 'parent/child.html' context_object_name = 'filtered_customers' @method_decorator(login_required) def dispatch(self, *args, **kwargs): return super().dispatch(*args, **kwargs) def get_context_data(self, *args, **kwargs): context = super().get_context_data(*args, **kwargs) context['form1'] = FilterForm(initial={ 'name': self.request.GET.get('name', ''), 'filter_field': self.request.GET.get('filter_field', '') }) context['users'] = self.request.user context['form'] = Customer() return context def get_queryset(self): query = self.request.GET.get('name') filter_field = self.request.GET.get('filter_field') if query: return CustomerName.objects.filter( Q(('%s__icontains' % filter_field, query)) ) else: return {} child.html <form method="GET"> <legend class="border-bottom mb-4">Customer Lookup</legend> <fieldset class="form-group"> {{ form1|crispy }} </fieldset> <div class="form-group"> <input type="submit" class="btn btn-outline-info mt-4" value="Search" onclick="showDiv"> </div> </form> <hr> <div class="table-responsive" id="custTabDiv" style="display:none"> <table id="testTable" class="table table-striped table-hover" cellspacing="0" width="100%"> <thead> <tr> <th … -
Why is this Django DivErrorList being escaped?
I created a DivErrorList class as in these instructions or this stackoverflow answer. To repeat: from django.forms.utils import ErrorList class DivErrorList(ErrorList): def __str__(self): return self.as_divs() def as_divs(self): if not self: return '' return '<div class="errorlist">%s</div>' % ''.join(['<div class="error">%s</div>' % e for e in self]) When I use the class as an error_class in a form, I get escaped text. So instead of divs in my page, I get text saying <div class="errorlist">.... I had to add mark_safe to as_divs to get it to work. Is there a reason the example does not have mark_safe, but I need to add it to make it work? Is there some context I'm missing about what is escaped and what isn't? -

Initializing Django model field with the model field from the same Model temporarily
I am building a trip reservation app in Django 2.1 and have some problem with updating available seats in the car for the trip. Your help would be greatly appreciated) Here below, I have my first model, I am trying to initialize available_seats with seats just for the first time when the model will be created. First, I tried below method class Trip(models.Model): origin = models.CharField(max_length=120) destination = models.CharField(max_length=120) time_date = models.DateTimeField(auto_now=True) arrival_time = models.DateTimeField() trip_cost = models.IntegerField() vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE) seats = models.IntegerField() available_seats = models.IntegerField(default=seats) yes, this method doesn't work because it is not possible to assign a variable to the one which is not defined yet. Thus, I come with solutions that I need to rewrite the save() method of the model or use signals to accomplish what i want. So, I did: class Trip(models.Model): origin = models.CharField(max_length=120) destination = models.CharField(max_length=120) time_date = models.DateTimeField(auto_now=True) arrival_time = models.DateTimeField() trip_cost = models.IntegerField() vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE) seats = models.IntegerField() available_seats = models.IntegerField() #rewriting save() method # def save(self, created=False, *args, **kwargs): # if created: # self.available_seats = self.seats # super().save(*args, **kwargs) #using signals @receiver(pre_save, sender=Trip) def default_available_seats(sender, instance=Trip, created, **kwargs): if created: instance.available_seats = instance.seats These two ways … -

django update view not showing date input (previous) values
when I go to the update page, all previous values are shown except date inputs (deadline and reminder). how can I fix it? At first I didnt use TaskCreationForm for TaskUpdateView considering django will handle it automatically, but then the date inputs became normal text inputs and therefore no datepicker would appear when clicking on the textbox.

Empty Queryset upon requesting TemplateView
