django model get field method
I have a requirement, when a field say Price in a django model Lead is accessed I have to apply some business logic and update the price. I can accomplish in Serializers / Views. However this object is accessed by several views and hence its not a viable design to have a code in several place. So i'm looking for a way where i can get control like get_price(self). class Lead(models.Model): price = models.IntegerField(_('price'), default=10) def get_price(self): ''' Looking for something like this ''' get_price to be called when any serializers/ views access this model. -

Trouble updating BooleanField with Django ModelForm
Using Django 1.11 and Python 3.4 I have a model: class ToDo(models.Model): completed = models.BooleanField(default=False) I want users to be able to update this field for the model by clicking a checkbox, so I made a ModelForm as follows: class CompletedForm(ModelForm): class Meta: model = ToDo fields = ['completed'] The problem I am having is understanding how I can get the database to update whenever the user clicks the checkbox, so that the completed field will toggle between True or False. In views.py: if request.method == 'POST': for x in range(0, all_todos.count()): a = all_todos[x] completedform = CompletedForm(request.POST, instance=a) else: for x in range(0, all_todos.count()): a = all_todos[x] print(a) completedform = CompletedForm(instance=a) I've rendered the checkboxes in the event of either GET or POST method, and linked each box to a particular instance. I assume that most of the logic will take place in the POST method since this is making a change to the database. Thank you -

Python Django button not redirecting correctly according to URL
I implemented my own map-search form such that once map-search is clicked it would use the onclick search function. function search() { var query = document.getElementById("search").value; if (query == ""){ $("#button-group").addClass("hidden"); }else{ $("#button-group").removeClass("hidden"); jsonLayer.clearLayers(); $.getJSON('http://localhost:8000/search/'+ query, function (boundary) { jsonData = boundary[0].geojson; jsonLayer.addData(jsonData); lon = boundary[0].lon; lat = boundary[0].lat; boundingbox = boundary[0].boundingbox; map.fitBounds([ [boundingbox[0],boundingbox[2]], [boundingbox[1],boundingbox[3]] ]); }); } } After that function is fired, the button-group, that is initially hidden will be revealed. I tried clicking one of the buttons that was revealed which I have set to go to another template in Django but instead it will append in the url my query resulting to: http://localhost:8000/?search=Test <div class="col-lg-offset-3 col-lg-6"> <div class="input-group"> <input id="search" name="search" type="text" class="map-search form-control input-sm"> <span class="input-group-btn"> <button class="map-search btn btn-default btn-sm" type="button" onclick="search()"> <span class="glyphicon glyphicon-search"></span> </button> </span> </div> <div id="button-group" class="button-group hidden"> <a href="{% url 'trips_view' %}"><button class="btn btn-primary btn-lg btn-space col-sm-3">View Trips</button></a> <a href="{% url 'manage' %}"><button class="btn btn-primary btn-lg btn-space col-sm-3">Manage Trips</button></a> </div> </div> My Url url(r'^view/', views.trips_view, name='trips_view') I checked my network and it would go in this order: 1.) localhost:8000 2.)

Cannot connect to remote PostgreSQL instance from Django app running within Docker container
I am trying to connect a Django app running inside of a docker container to a PostgreSQL database running on another computer (lets say with an IP address of 192.168.1.22). Thus far in my experimentation, I always get the following error when attempting to connect to the PostgreSQL instance from a docker container (my code works fine outside of the docker container): Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432? I've made sure that I allow all inbound connections to the PostgreSQL database (by changing the config file for my PostgreSQL server as recommended here.

data How to keep form when user gets redirected back to the form when they fail a validation (Python, Django)?
I know this might be a duplicate question, but the previous one was an older question and those questions uses a form instance which doesn't really help me. How do I keep my form data after a failed validation? I have multiple dropdowns and input fields and I hate to see my users re-do and re-type everything when they fail validation in the backend. Let's say I have this very simple form: HTML: <form class="" action="/register" method="post"> <label for="">First Name</label> <input type="text" name="" value=""> <label for="">Last Name</label> <input type="text" name="" value=""> <label for="">Password</label> <input type="password" name="" value=""> </form> views.py: def register(self): ..... if errors: for err in errors messages.errors(request, err) return redirect('/') else: messages.success(request, "Welcome User!") return redirect('/dashboard') Most examples that I came across were using the form instance which uses form.save() etc. I opted out on that one. Is there a way to auto-populate my form with the data that the user submitted if they were to fail validation? Thanks! -
ModelSerializer is not saving changes to DATA when passed back to the view in DRF but are shown in the serializer
I've seen several questions that sound related on SO and GitHub, but I haven't been able to resolve my issue. Also read through the ModelSerializer section in the DRF documentation: http://www.django-rest-framework.org/api-guide/serializers/#modelserializer Anyway, I am sending part of unique URL that is emailed to the user to DRF for validation. When it has been validated it should allow the user to answer the security questions associated with the account. It is supposed to update the data object with the security questions so that they can be rendered in React. When I print(data), it shows the sq1 and sq2 that I set while still in the serializer. When it gets back to the view.py, and I print out print(new_data), it is just showing the original data sent from React to the API. From what I gather it is related to ModelSerializer, but am not finding a fix for my situation. How do I update the data so it returns my changes back to the ./view.py and React? # ./views.py class ValidateKeyAPIView(APIView): permission_classes = [AllowAny] serializer_class = ValidateKeySerializer def post(self, request, *args, **kwargs): data = request.data serializer = ValidateKeySerializer(data=data) if serializer.is_valid(raise_exception=True): new_data = serializer.data print(new_data) return Response(new_data, status=HTTP_200_OK) return Response(serializer.errors, status=HTTP_400_BAD_REQUEST) # ./serializers.py … -

Deploying with zappa, Django project in subfolder
I'm new to Docker, AWS Lambda and Zappa, but I'm trying to configure a project with very little success. I connect to Docker (docker-compose run web bash), activate the environment, configure the AWS credentials and run zappa init and zappa deploy. However, after deployment I get an error (executing zappa tail): ModuleNotFoundError: No module named 'project' I believe that that's because my dir structure is not the standard: Dockerfile zappa_settings.json requirements.txt project\ - manage.py - root\ - settings.py - wsgi.py - ... So, my django project is inside the project folder, as I don't like having all the files thrown there and mixed with other configuration files. My zappa config file looks like this: { "dev": { "aws_region": "us-east-2", "django_settings": "project.root.settings", "profile_name": "default", "project_name": "task", "runtime": "python3.6", "s3_bucket": "bucket-name" } } And Dockerfile: FROM lambci/lambda:build-python3.6 # Copy in your requirements file ADD requirements.txt /requirements.txt # Copy your application code to the container RUN mkdir /code/ WORKDIR /code/ ADD . /code/ ENV PS1 'zappa@$(pwd | sed "s@^/var/task/\?@@")\$ ' ADD zappa_settings.json /var/task/zappa_settings.json WORKDIR /var/task RUN virtualenv /var/venv && \ source /var/venv/bin/activate && \ pip install -U pip zappa && \ pip install -r /requirements.txt && \ deactivate CMD ["zappa"] Can you tell … -
Django custom filter error. Returns "invalid filter"
I've been trying to create this custom filter in Django, and I can't for the life of me make it work. in my templatetags folder I have the files __init__.py and alcextra.py in my template I first load the static files and then the templatetags. I've tried reseting the server and deleting and creating the files again. {% load staticfiles %} {% load alcextra %} Which is then extended to my main html file. I have tried putting it in the main html file. in alcextra.py I have written from django import template register = template.Library() @register.filter def multiply(value, arg): return value * arg I have tried loads of different @register versions like @register.filter("multiply", multiply) @register.filter(name="multiply") @register.filter() @register.simple_tag(takes_context=True And all return the same error, invalid filter: 'multiply'.

Wagtail admin - default ordering of child pages
In the admin area I have to activate the "Enable ordering of child pages" every time. Is there a way to set this as a permanent option? The main problem is that the listing in the child pages view changes depending on if this is activated or not(if you have changed the ordering), which might be a bit confusing for some. Potentially one could change the default ordering of the children list to match the manually ordered list somehow? -
How to route a multi-part form in django
I'd like my users to be able to place orders. For this kind of order, the user uploads a csv. The app parses, the CSV, serializes the data, and then needs to show the user a new view with the data and a "confirm order" button. I'm not sure how to do this in django. class UploadSampleSheetView(LoginRequiredMixin, FormView): form_class = UploadSampleSheetForm template_name = 'pages/upload.html' def form_valid(self, form): uploaded_sample_sheet = self.request.FILES['uploaded_sample_sheet'] sample = _parse_sample_sheet_to_sample_model(uploaded_sample_sheet) sample.save() return super().form_valid(form) def get_success_url(self): return reverse("orders:create") # how do I get the data over? class CreateOrderView(LoginRequiredMixin, CreateView): model = Order form_class = NewOrderForm template_name = 'pages/complete_order.html' What I'm looking for is some way that, on success, the UploadSampleSheetView can return a CreateOrderView with sample data. In general, I'd love to be pointed to a reference about how to build user flows like this one. How does one view defer to another? I'm seeing a lot of return HttpResponseRedirect('url') which seems a little messy. How do I pass data around views? -
