Exclude instance user from Django autocomplete light form
I am trying to do 3 things. 1) exclude the instance user from a django autocomplete light dropdown, 2) restrict that user from being chosen (in the backend), and 3) customize the validation message if that user is chosen. As of now, I have #2 that seems to be working, but I cannot figure out how to change the validation error message and how to exclude it from the drop down all together.

Passing model object between views django (Object is not JSON serializable)
I've made model objects for my forms (Didn't use form models) and I want the user to progressively fill out the model as they go through the different web pages (views).

ModelChoiceField widget attrs have no effect
I have this model form that I have to render manually but the ModelChoiceField attributes don't have any effect. class ExtendedUserForm(forms.ModelForm): favourite_provider = forms.ModelChoiceField(queryset=Provider.objects.all()) class Meta: EXPERTISE_CHOICES = ( ('N', 'Novice'), ('B', 'Beginner'), ('I', 'Intermediate'), ('E', 'Expert'), ) model = ExtendedUser labels = { 'expertise': 'Expertise', 'favourite_provider': 'Favourite provider', 'job_title': 'Job title', 'job_place': 'Company/Institution', } widgets = { 'expertise': forms.Select(choices=EXPERTISE_CHOICES, attrs={'class': 'form-control'}), 'favourite_provider': forms.Select(attrs={'class': 'form-control'}), 'job_title': forms.TextInput(attrs={'placeholder': 'Your job title', 'class': 'form-control'}), 'job_place': forms.TextInput(attrs={'placeholder': 'Your company/institution', 'class': 'form-control'}), } exclude = ['user', 'history', 'favourite_services'] The rendered HTML is as follow: <div class="form-group"> <label><label for="id_expertise">Expertise:</label></label> <select name="expertise" required id="id_expertise" class="form-control"> <option value="" selected>---------</option> <option value="N">Novice</option> <option value="B">Beginner</option> <option value="C">Competent</option> <option value="P">Proficient</option> <option value="E">Expert</option> </select> </div> <div class="form-group"> <label><label for="id_favourite_provider">Favourite provider:</label></label> <select name="favourite_provider" required id="id_favourite_provider"> <option value="" selected>---------</option> <option value="1">AWS</option> </select> As you can see the second select doesn't have the class attribute despite that I precised that here 'favourite_provider': forms.Select(attrs={'class': 'form-control'}).

All users see the same login input content online for different web application instances
I have React + Django app. The problem is when two different users in different machines tries to log in they are seeing the same input. It's like a magic singletone.

Django Rest AttributeError at /api/v1/person 'ConfigurationSerializer' object has no attribute 'initial_data'
models.py class Configuration(mongoengine.DynamicEmbeddedDocument): storage = mongoengine.IntField(required=True) notify = mongoengine.BooleanField(required=True) class PolicyConfig(mongoengine.DynamicDocument): account_id = mongoengine.StringField(required=True) policy_id = mongoengine.StringField(required=True) configuration = mongoengine.EmbeddedDocumentListField(Configuration) serializers.py class ConfigurationSerializer(serializers.EmbeddedDocumentSerializer, serializers.DynamicDocumentSerializer): class Meta: model = Configuration fields = '__all__' class PolicyConfigurationSerializer(serializers.DynamicDocumentSerializer): configuration = ConfigurationSerializer(many=True) class Meta: model = PolicyConfig fields = '__all__' Here is what my typical document looks like: { "account_id": "11231354", "policy_id": "AAAABBBQAA", "configuration": [{"storage": 151, "notify": false}] } The requirements to it as follows: Both Configuration and PolicyConfig must be expandable (dynamic) documents meaning their fields may appear and disappear and it's fine but I would also like to verify some fields. The whole thing does work if I change configuration = mongoengine.EmbeddedDocumentListField(Configuration) to configuration = mongoengine.EmbeddedDocumentField(Configuration) and inside the PolicyConfigurationSerializer set configuration = ConfigurationSerializer(many=False). The object looks this way: { "account_id": "11231354", "policy_id": "AAAABBBQAA", "configuration": {"storage": 151, "notify": false} } This way it works but I have a problem trying to make the configuration field a list, not another document... I've tried to do it for too long, I've totally run out of any sane ideas what might be causing the issue. It yields the AttributeError at /api/v1/person 'ConfigurationSerializer' object has no attribute 'initial_data' error. -

JavaScript list import in Django
I'm trying to implement a map in my website using Google v3 API. I'm trying to save the coordinates of a path in the server that the user generates by clicking on the map. I'm doing all this in JavaScript since the API is in JavaScript. For the backend I'm using Django. When I'm creating the path, everything gets stored in a JavaScript array. My question is, how do I store that array in a django model? My research until now has not been successful and most people suggest using geodjango for the project. But I personally found it very complicated so I only expect answers that are regarding the google map API. -

Will Django allow requests from multiple Ajax function with one AjaxSetup that contains csrf?
The title can't handle my question completely, sorry. I have three Ajax function in my Django template. First one sends comment requests, the second one updates a value to database and the third one manages login/register process. All of them are being triggered by a button. As you know, Django says that use CSRF on your Ajax requests too. So, I use like this: function csrfSafeMethod(method) { // these HTTP methods do not require CSRF protection return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } var csrftoken = $('input[name=csrfmiddlewaretoken]').val(); $.ajaxSetup({ beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } }); Can this function handle all my Ajax requests in one template? Do I need to do extra stuff? -
Can't access all the Values from django MultiWidget, from request.POST?
I'm unsure why I cannot access both fields from the MutliWidget after the post request. I've tried various things such as request.POST.get('name'), which just returns 0 I've also tried accessing the values from value_from_datadict(self, data, files, name) with no luck. What confuses me the most is when I use print(request.POST) I can see that the form inside the post request does contain both values of the MultiWidget, however I can only access one for instance when I print request.POST, this is printed to the console: <QueryDict: {'total_travel_time': ['0', '0']}> however when I try: request.POST.get('total_travel_time') I only receive 0.

Exponential backoff in kubernetes?
I am new to kubernetes and I am having trouble tracking down an exponential backoff signal I am observing on my Jmeter load tests for response times. I have a kubernetes service that is running between 4-32 pods with horizontal pod autoscaling. Each pod is running a Gunicorn WSGI serving a django backend. All of the different k8s services are behind nginx reverse proxy, which redirects incoming traffic directly to Service’s VIP. Nginx sits behind Amazon ELB which is exposed to end-user web traffic. ELB ultimately times out a request after 60 secs. Each gunicorn server is running one worker with 3 greenlets and has a backlog limit of 1. So it can only server 4 requests at any given time and immediately returns an error response for any extra requests nginx tries to send its way. I am guessing that these error requests are then being caught and retried with exponential backoff, but I can’t quite make out where this is happening. As far as I know, nginx can’t be the source for the exponential retries, as it is serving only one upstream endpoint for a request. And I couldn’t find anything in the documentation that discusses exponentially timed … -
