Manually Adding Formsets Django
I'm so stuck on this problem. I have a use case where I have a formset which can be populated from existing objects on click of a button. For this, I have written a script which deletes the existing forms in the formset and replaces the HTML elements. Essentially, manifest-table25 gets deleted and the empty form gets appended to that div. {{ form2.management_form }} {% for form2 in form2.forms %} <div id="form_set"> <table id = 'manifest-table25' class="manifest-table2" width=100%> {% csrf_token %} <tbody width=100%> <tr class="manifest-row"> <td width = 17.5% class="productCode" onchange="populateProduct(this)">{{form2.ProductCode}}</td> <td width = 32.5% class="description">{{form2.DescriptionOfGoods}}</td> <td width = 12.5% class="quantity" oninput="calculateUnit(this)">{{form2.UnitQty}}</td> <td width = 12.5% class="unitType">{{form2.Type}}</td> <td width = 12.5% class="price" oninput="calculate(this)">{{form2.Price}}</td> <td width = 12.5% class="amount2">{{form2.Amount}}</td> {{form2.id}} </tr> </tbody> </table> </div> {% endfor %} <div id="empty_form" style="display:none"> <table id="manifest-table200" class='manifest-table2' width=100%> {% csrf_token %} <tr class="manifest-row1"> <td width = 17.5% class="productCode" onchange="populateProduct(this)">{{form2.empty_form.ProductCode}}</td> <td width = 32.5% class="description">{{form2.empty_form.DescriptionOfGoods}}</td> <td width = 12.5% class="quantity" oninput="calculateUnit(this)">{{form2.empty_form.UnitQty}}</td> <td width = 12.5% class="unitType">{{form2.empty_form.Type}}</td> <td width = 12.5% class ="price" oninput="calculate(this)">{{form2.empty_form.Price}}</td> <td width = 12.5% class="amount2">{{form2.empty_form.Amount}}</td> {{form2.id}} </tr> </table> </div> The issue is that the form id does not get added. So I get a MultiValue Dict Key error. I understand that when submitting … -

django can't show a template - how to fix
I just made the app users to validate user that is already registered in database. Included url inside project directory(urls.py), executed the login page in urls.py from app directory, made the template and a link refer in base.html. It all works, however when click Login link return this error: TemplateDoesNotExist at users/login/ I tried to rename the path according tree navigation but always return this same error.

How to troubleshoot xhr eventListener
I have a modal window called on an AJAX request which suddenly stopped working. I have narrowed it down to the XMLHttpRequest object: $.ajax({ xhr: function() { var xhr = new XMLHttpRequest(); xhr.upload.addEventListener('progress', function(e) { console.log('Event listener') if (e.lengthComputable) { console.log('Length computable') showPleaseWaitWindow(); console.log('Percentage uploaded: ' + (e.loaded / e.total)) var percent = Math.round(e.loaded / e.total * 100); $('#progress-bar').attr('aria-valuenow', percent).css('width', percent + '%'); } else { showPleaseWaitWindow(); console.log(e.lengthComputable); } }); return xhr; }, None of these console.log();s print a statement. Inside my view I am able to print success to show it is in-fact an AJAX request. And the response is showing success: success: function(data){ if (data.success) { console.log("success"); window.location.href = data.url; } Why is the eventListener for the 'progress' not working? Or better yet, how do I troubleshoot this further? -
Django Count and Sum Results Too High
I have the following models (simplified): class Post(...): user = ... class Comment(...): post = Post(...) class Vote(...): vote = Either -1 or 1 post = Post(...) I want to know, for a given Post, how many comments it has + what the vote total is. I've written out a ton of queries, but I end up getting 3-4x the actual value. I don't want to settle and use distinct; the join is broken. I've read about using a Subquery, but no results. -
Django - Change date format for filtering a queryset
I've got a datatable on a website, using server-side processing (I'm using django-datatables-view for that). My problem is on the search field. It works fine if I pass a date as expected: %Y-%m-%d. However, I want to return values when passing values like %d/%m/%Y. Here's a sample of my code: def filter_queryset(self, qs): search = self.request.GET.get('search[value]', None) if search: qs = qs.filter( Q(pk__contains=search) | Q(client__first_name__unaccent__icontains=search) | Q(client__fantasy_name__unaccent__icontains=search) | Q(created_at__date__contains=search) | Q(proposal__pk__contains=search) | Q(total_value__contains=search) | Q(engeneering_value__contains=search) ) return qs I've tried strptime(), but if the user passes a value that isn't exactly a full date, the request returns a 500 response. -

Showing dict of lists with Jinja2 in HML Table

Displaying Maps in a Form
The back end is now working correctly. Now I want to create a form for the front end. models.py from django.contrib.gis.db import models from django.contrib.auth.models import User NO_OF_HRS = (('1', 'Office'),('2', 'Home')) class Home(models.Model): User = models.ForeignKey(User, on_delete=models.CASCADE) Location = models.PointField() City = models.CharField(max_length=50) Street = models.CharField(max_length=60, default="") PostCode = models.CharField(max_length=60, default="") Residential = models.CharField(choices=NO_OF_HRS, max_length=60, default='1') form.py from houses.models import Home from django import forms from django.contrib.gis import forms as geoforms from django.forms import TextInput User and Residential rendered correctly. But with Location there is a white square where a map should ideally be. class ContactForm(forms.ModelForm): class Meta: model = Home fields = ('User', 'Residential', 'Location') I then googled the problem and saw people talking about widgets. These are succesful experiments I did with widgets to try and get a better understanding of them. #description = forms.CharField(widget = forms.CheckboxInput) #title = forms.CharField(widget = forms.Textarea) #description = forms.CharField(widget = forms.CheckboxInput) #views = forms.IntegerField(widget = forms.TextInput) #name = forms.CharField( widget=forms.Textarea(attrs={'rows': 25, 'cols': 100})) #name = forms.CharField( widget=forms.Textarea(attrs={'rows': 40})) #address_2 = forms.CharField( # widget=forms.TextInput(attrs={'placeholder': 'Apartment, studio, or floor'}) #) #check_me_out = forms.BooleanField(required=False) #zip_code = forms.CharField(label='Zippy iii') #password = forms.CharField(widget=forms.PasswordInput()) #address_1 = forms.CharField( # label='Address test', # widget=forms.TextInput(attrs={'placeholder': '1234 Main St'}) #) These … -
Is Django .values() nontrivially more effecient than ORM?
In this Django documentation it states: "When you only want a dict or list of values, and don’t need ORM model objects, make appropriate usage of values()" I have a Table with about 100 columns, some of which are Foreign Keys to other models. I would like to know if using .values() with the following queries would be more performant: Queries that only make use of 20 columns Queries that make use of all 100 columns Please let me know if there is more information I can provide, I'll add it promptly :) -
Django model stoped working when adding more models
I have a view in which the user can edit their profile everything worked fine and everything was being updated (biography, first_name, username, email and profile-picture) but now that I added a new app that contains three views in which the user can upload, delete and like posts, the user update sistem stoped working for some reason just the (update, email, first_name)still worked.

How update foreign key for several instances in Django formset
I just need to show the list of all Child instances without a parent, when a new Parent is created, so a user can set a checkbox in front of those he would like to add to this parent How to deal with this? I need to let people assign Foreign key to a number of Child instances in django formset. I can't figure out how to do this: models.py: class Parent(models.Model): pass class Child(models.Model): owner = models.ForeignKey(to=Parent, null=True) forms.py: class PartFormset(forms.BaseInlineFormSet): model = Child def get_queryset(self): return self.model.objects.filter(owner__isnull=True) MyFormSet = inlineformset_factory(parent_model=Parent, model=Child, formset=PartFormset, extra=0, can_delete=False, ) this one obviously doesn't work because inlineformset_factory misses fields argument. But of course if I provide the 'owner' as a field, that doesn't work either. -

Why can't this method in a server be found?
I am working on a new Django project that we uploaded to a server. The problem is that there is a method that is supposed to be called by an API we made. That API is used in another project, and that project works fine.

Django: how to add custom fields to data on form save?
I want to insert some custom variable eg Status into the model when the user submits the form. I want the field status to be updated to Pending when a new record is inserted. This should be done automatically when the user inserts a new form. I know how to insert the form with values set by the user how can i insert my own values instead.

Ive been following a tutorial on YouTube ( Django Ecommerce Website | Add to Cart Functionality | Part 3) and at (20:56 - 23:00) i keep getting this error. Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0 I followed every thing he did i even spent a few days backtracking through my code and i still cant get this error to go away, Ive only been coding for a few weeks so i probably need more knowledge on java script.But for the time being i wanna see if i can get some help from you guys,Thanks in advance!! -
