I am using intercooler.js in a django project. http://intercoolerjs.org <div id=right-side> <form ic-post-to="{% url 'update-task-ajax' %}" ic-target="#right_side"> [...] </form> </div> The form itself gets reloaded in the div #right-side after the first use and intercooler is not working anymore.

ValidationError : [u'ManagementForm data is missing or has been tampered with'] on Django template page when I try to view my formset
Django version 1.8.7 I'm creating a pages where the user has to add a list of invitees to his weeding so I needed to use the same form many times on the same page to create mnay model instances of the invitees; In order to do that I used model formsets using modelformset_factory function . So in my forms.py class InviteesForm(ModelForm): class Meta: model = Invitees fields = ['user', 'invitee_name' , 'invitee_address', 'invitee_count', 'invitee_email'] exclude = ('user',) #creating a formset InviteesFormSet = modelformset_factory(Invitees, form = InviteesForm ) Above you can see my model form for the invitees model and my InviteesFormSet which uses modelformser_factory fucntion. In my views.py def preview(request): formset = forms.InviteesFormSet(queryset=Invitees.objects.all()) if request.method == 'POST': formset = forms.InviteesFormSet(request.POST) if formset.is_valid(): formset.save(commit = False) return redirect('/invitees/') else: formset = forms.InviteesFormSet(request.POST) return render(request, 'preview.html', {'formset': formset} ) In my Preview.html <form action="/preview/" method='POST'> {% csrf_token %} {{ formset }} <button type="submit">Add an Invitee</button> </form> The formset is not rendering in my html, am not sure what I'm doing wrong here, it's basic code! but I get this error [u'ManagementForm data is missing or has been tampered with'] Can you please help me figure out the issue? Thanks -
Foregin key field name is followed by _id
In a model, when a foreign key field is created then Django apparently create another field with the same field name followed by _id. for example if I have class Post(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE,default=None) dated = models.DateTimeField(auto_now=True) ... then I will have the following fields available: id,user,user_id,dated I am not sure why this field (user_id) was added? later I wanted to override my queryset in a class view so I was confused which one to use (user field or user_id field) : def get_queryset(self): queryset = super().get_queryset() return queryset.filter(user_id=self.request.user.id) and def get_queryset(self): queryset = super().get_queryset() return queryset.filter(user=self.request.user.id) I tried both and both worked just fine My question is: 1) what is the purpose of creating this additional field ? 2) what is the difference between the original foreign key field (user in my case) and user_id field? 3) will this added field (user_id) only be visible to the database or user field also? 4) is the content identical in user and user_id for each record? if so ,then what the purpose of this additional field that was created automatically by django? Thanks a lot -

Connect django+mongoengine to remote mongodb
I have a web app written in Django with mongoengine in a Digital Ocean droplet. During the developing step I used a sample of the main database that is located in a remote enviroment. But now I want to connect the Django web app to the main MongoDB database. How can I do this? With an ssh tunnel (I already use it between both environments)? If so, how do I do such connection? I know how to establish an ssh tunnel with pymongo: from sshtunnel import SSHTunnelForwarder import pymongo server = SSHTunnelForwarder( (remote_ip_address, 22), ssh_private_key="/home/username/.ssh/id_rsa", ssh_username="username", remote_bind_address=('127.0.0.1', 27017), ) server.start() client = pymongo.MongoClient('127.0.0.1', server.local_bind_port) But how do I do the equivalent connection with the Django web app? At the present moment I have the following definitions in the settings.py file. # MongoDB settings MONGODB_DATABASES = {'default': {'name':'dbname'} } DATABASES = {'default': {'ENGINE': 'django.db.backends.dummy'} } -
How do you unit test Django RawQuerySets
I'm using raw() and annotate() on a Django query and need some way to test it. Here's what my code looks like (this is simplified significantly) query = """SELECT table1.id, table1.column1, table1.column2, table2.other_column1, table2.other_column2 FROM myapp_mymodel as table1 JOIN otherapp_othermodel as table2 ON table1.othermodel_id = table2.id""" return MyModel.objects.annotate( other_column1=models.Value('other_column1', models.IntegerField()), other_column2=models.Value('other_column2', models.DateField()) ).raw(query) It's relatively straightforward to fill the database with sample data, but what's the best way to check that the data is returned by this code? There are a lot of options when dealing with standard querysets that seem to go out the window when dealing with RawQuerySets. -
Deleting an item in django after clicking a button in a pop up
I want to create a pop up which opens up clicking the button 'Dissolve'. The pop up should say: 'Are you sure you want to delete this field?' and have two buttons: Okay and Cancel.

Object id is missing in Django framework when posted from AngularJS MongoDB

CSRF tokens from Angular 4 to Django
This is a follow-up question to a question I asked yesterday: CSRF token in Angular 4 CLI from Django I have a backend Django server and a frontend Angular app. I am trying to submit a form in Angular to the Django backend with a POST. The problem is with CSRF tokens. This is the Django view: #@csrf_exempt def empty_form(request): if request.method=="POST": message = "Post" else: message = "Get" return JsonResponse({'message': message}) And this is the Angular component: send_sample_form() { let d = new Date(); d.setTime(d.getTime() + 1 * 24 * 60 * 60 * 1000); let expires:string = "expires=" + d.toUTCString(); let cpath:string = '/'; // this.cookieService.set('csrftoken', this.server_token, d, cpath, '127.0.0.1', false); this.cookieService.set('csrftoken', this.server_token); let my_headers = new HttpHeaders( { 'X-CSRFToken': this.server_token } ); this.http.post('http://127.0.0.1:8000/emptyform/', {'my_form': this.sample_form.value}, {headers: this.server_token, withCredentials: true}) .subscribe( (response) => { console.log(response); } ); } When the Angular and Django are separate servers (localhost:4200 and 127.0.0.1:8000), the angular code does not get the CSRF token. When I run it in production mode and so there is only the Django server at 127.0.0.1:8000, now the Angular component is able to extract the CSRF token with: ngOnInit() { this.http.get('http://127.0.0.1:8000/generate_token/', { observe: 'response' }) .subscribe( (response) => { … -

Javascript doesn't work in the Django Template
I am trying to create a CSS modal for multiple images. The Javascript doesn't seem to be working, though. Where am I going wrong in the following code?: sometemplate.html: {% extends 'base.html' %} {% load staticfiles %} {% block styles %} <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="{% static 'photo.js' %}"></script> <link rel="stylesheet" href="{% static '/css/photos.css' %}" type="text/css"> {% endblock %} {% block content %} <div id="myModal" class="modal"> <span class="close" onclick="document.getElementById('myModal').style.display='none'">&times;</span> <img class="modal-content" id="img01"> <div id="caption"></div> </div> <img class="myImg" src="{% static 'images/angy1.jpeg' %}" alt="Normandy, France" width="300" height="200"> <img class="myImg" src="{% static 'images/angy2.jpeg' %}" alt="Delft, Holland" width="300" height="200"> {% endblock %} photo.js var modal = document.getElementById('myModal'); var img = $('.myImg'); var modalImg = $("#img01"); var captionText = document.getElementById("caption"); $('.myImg').click(function(){ modal.style.display = "block"; var newSrc = this.src; modalImg.attr('src', newSrc); captionText.innerHTML = this.alt; }); var span = document.getElementsByClassName("close")[0]; span.onclick = function() { modal.style.display = "none"; }
