How to access a Django form field through HTML?
This is how the Django form is written in the html file: <form method='post' action="{%url 'getNewAbstracts' %}"> {% csrf_token %} {{editViewAbstractForm|crispy }} <input type="submit" value="Submit" class="btn btn-primary"> <br><br> </form> This is the form written in the django forms file: class editViewAbstract(forms.ModelForm): class Meta: model = abstract `enter code here` fields = ['abstractTitle', 'publicationDate', 'pmid', 'leadAuthor', 'publicationName', 'abstractBody', 'keywordIdList', 'currentStatus'] I am trying to access a specific field of the form for example the field abstractTitle and change the value of that input box through the html file. The reason is that I need to change the fill-text in the Django form every time that a html button is clicked without reloading the page. What is the best way to do this? Thank you for your help. -

Display different inputs based on one form field in Django
So I've got my models - 'product' from CartItem is a foreign key of a Product: class Product(models.Model): name = models.CharField(max_length=64, verbose_name=_('Name')) type = models.ForeignKey('pizza.ProductType', related_name='pizza', on_delete=models.CASCADE, verbose_name=_('Type')) size = models.ForeignKey('pizza.Size', related_name='pizza', on_delete=models.CASCADE, verbose_name=_('Size')) price = models.DecimalField(max_digits=4, decimal_places=2, verbose_name=_('Price')) class CartItem(models.Model): user = models.ForeignKey('accounts.CustomUser', related_name='carts', on_delete=models.CASCADE, verbose_name='User') product = models.ForeignKey('pizza.Product', related_name='carts', on_delete=models.CASCADE, verbose_name=_('Product')) quantity = models.SmallIntegerField(verbose_name=_('Quantity')) toppings = models.ManyToManyField('pizza.Topping', related_name='cart_items', blank=True) extras = models.ManyToManyField('pizza.SubExtra', related_name='cart_items', blank=True) And I want to use a CreateView to add a product to user cart, but I want a user to choose Product Type and Product Size and based on that selection I would add a product to cart, so instead of the field 'product' in form, I would like user to see 'product__type' and 'product__size' in the form. I tried with something like that, but it doesn't work: class CartItemForm(forms.ModelForm): class Meta: model = CartItem fields = ['product__type', 'product__size', 'quantity', 'toppings', 'extras'] Is there a way to do it? -
In Django with Django REST Framework, what is the best way to update old objects when adding new field?
I have a database with a model that I'm updating by adding a new field. When I added the field, all the old objects in the database populated that field with an empty string value. I need these fields to have values. In the future, objects be forced to contain a value by either specification or a default value. What is the best way to update this field for the old objects? I have a couple ideas but I'm not sure if one is 'proper.' Again, this is something that only needs to be done once, as all future objects will have all required data. Enable PUT by adding the UpdateModelMixin to the ViewSet, then disable PUT (I do not want PUT permanently allowed) Create some sort of migration script to do the updates for me. Something I'm missing? -
Switch from using one database to having one for auth and one for everything else
Within my Django app I currently only have one DB, under settings it is default. What I want to do is port over all of the Auth tables created by Django to a separate database, Ill say SiteAuth for now. I have copied all of the auth tables over to the SiteAuth db, but I am not sure how to integrate those changes within the site. I know I am going to have to add another db the databases section of settings, But I am not sure how to do the migrations, or how to specify which database I want to query. How would I do the migrations? how would I specify which database I want to query? how would my models.py change? Thanks for all the help! -
Django Urls - Template Issue {% url '' %}
When I started Django I used 1.11 and since then upgraded to 2.0. My urls worked and had no problems and I would imagine something has been updated but I keep going over the documentation and I can't see where the issue is.

Trouble opening a WEBSOCKET connection between Angular 2+ client and DJANGO backend
I am trying to open a websocket connection from my angular 2+ app with my Django backend using Django Channels. I went through this tutorial: https://www.youtube.com/watch?v=RVH05S1qab8 and managed to get everything working with the javascript portion written inline in a Django html template. But I am having issues simply opening a websocket connection when I migrated the front-end chat form to a separate angular 2 app. Both font-end and backends are hosted locally.

Django's rest/login returns wrong user model fields after login
I have created a custom user model using AbstractUser class which is working fine. To login a user i am using rest_auth package. on using url /auth/login, i am able to login the user, but the json that i am getting after login contains fields first_name and last_name which is not included in my custom user model i analyzed parent classes and found that serializer.py file in rest_auth package returns user model on verifying the credentials through authenticate method. i am not able to understand how authenticate method is working model- from django.db import models from django.contrib.auth.models import AbstractUser from django.utils.translation import ugettext_lazy as _ class User(AbstractUser): username = models.CharField(unique=True,max_length=30) email = models.EmailField(_('email address'), unique=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['username'] def __str__(self): return self.email class UserProfile(models.Model): user=models.OneToOneField(User,on_delete=models.CASCADE,related_name='profile') photo=models.ImageField(upload_to='uploads',blank=True,null=True) city=models.CharField(max_length=50,blank=True,null=True) dob=models.DateField(blank=True,null=True) firstname=models.CharField(max_length=50,blank=True,null=True) lastname=models.CharField(max_length=50,blank=True,null=True) serializer- from rest_framework import serializers from .models import User,UserProfile class UserProfileSerializers(serializers.ModelSerializer): class Meta: model = UserProfile fields = ('photo','city','dob') class UserSerializers(serializers.HyperlinkedModelSerializer): profile = UserProfileSerializers(required=True) class Meta: model = User fields = ('id','username','email','first_name','last_name','password','profile') def create(self, validated_data): profile_data = validated_data.pop('profile') password = validated_data.pop('password') user=User(**validated_data) user.set_password(password) user.save() UserProfile.objects.create(user=user,**profile_data) return user def update(self, instance, validated_data): profile_data = validated_data.pop('profile') profile = instance.profile print('hello') print(profile) instance.username = validated_data.get('username',instance.username) instance.email = validated_data.get('email',instance.email) instance.first_name = … -
How to add attributes to a Django form widget's media fields?
I can render media files for a django form, through a custom widget, like this: class TinyMCEWidget(Textarea): def __init__(self, attrs=None): if attrs is None: attrs = {} attrs.update({ 'class':'listing-template', }) super().__init__(attrs) class Media: js = ('https://cdn.tiny.cloud/1/my_api_key/tinymce/5/tinymce.min.js/',) But I need to add referrerpolicy="origin" to the script. Is there a way this can be done without a javascript hack? How can I add attributes to a widget's media fields through the widget or form class? This question shows how I can add an arbitrary amount of attributes to a form widget, but does not show how to add attributes to a widget's media fields, therefor my question is not a duplicate. -

Is it possible in Django to insert data in var/dynamic table name via Models META?
Thank you for reading i am new to Django and For my application it's a requirement to create a table for each client to store his data. Each client table has the same data so i made a Model for it. But the table name is variable: I tried to do this via the Meta: db_table: Other_function The table is not created and i get error. In the url the customername is available, als in the view as variable. I tried to do this via the Meta: db_table: get_create_table The table is not created and i get error. because the function needs the var instance get_create_table(instance) if (instance.organisation in connection.introspection.table_names()): return instance.organisation else: with connection.cursor() as c: c.execute("CREATE TABLE %s (organisation varchar(255)," "organisation_code varchar(255)," % instance.organisation)``` and in the model: ``` class Import(models.Model): class Meta: db_table = get_table_name() organisation = models.CharField(max_length=255) ``` i get of course and error for instance because it doesnt exists from the view. In the view i have: ``` model = Import() model.organisation = organisation model.save() ``` i also changed the model to: ``` class Import(models.Model): class Meta: db_table = get_table_name organisation = models.CharField(max_length=255) ``` but it doesnt create the table and gives errors. i would … -

How to extend Django groups for dynamic user types?
I have a SaaS project which many companies will use and within the companies there will be employees which will be applied to one of two groups: Supervisor or Non-Supervisor. This will probably look as such: class EmployeeGroup(Group): .... Each company will be able to create their own EmployeeType which falls into one of the EmployeeGroups. e.g. an EmployeeType may be Food and Beverage Supervisor which is an EmployeeGroup: Supervisor: class EmployeeType(models.Model): .... employee_type = models.CharField( max_length=32, default='Server' ) employee_group = models.ForeignKey( EmployeeGroup, null=True ) company = models.ForeignKey( Company, on_delete=models.CASCADE, null=True ) And obviously each User will have an EmployeeType: class User(AbstractUser): .... employee_type = models.ManyToManyField( EmployeeType, null=True, ) In this situation, can several companies share EmployeeGroups without sharing EmployeeTypes? My concern is that if an EmployeeType: Server is created at Company A then Company B will not be able to create an EmployeeType: Server as well. Or that if they do then information will get crossed. It wuold help to have an understanding of how the database works but I do not. Any links to external resources specific to this situation would be greatly appreciated! -

Heroku doesn't upload static files to S3 bucket in production: Possibly permission error
I configured my django app so that it uploads static and media files to S3. I configured everything that my static folder should be public. My media folder has one private and one public folder. Now, locally everything runs perfectly fine. My static files are public, my private media folder is private, my public media folder is public. In production a weird behaviour happens.

How to refresh cache from DB in django rest service?
The main intent of this question is to know how to refresh cache from db (which is populated by some other team not in our control) in django rest service which will then be used in serving requests received on rest end point. Currently I am using the following approach but my concern is since python (cpython with GIL) is not multithreaded then can we have following type of code in rest service where one thread is populating cache every 30 mins and main thread is serving requests on rest end point.Here is sample code only for illustration. # mainproject.__init__.py globaldict = {} # cache class MyThread(Thread): def __init__(self, event): Thread.__init__(self) self.stopped = event def run(self): while not self.stopped.wait(1800): refershcachefromdb() # function that takes around 5-6 mins for refreshing cache (global datastructure) from db refershcachefromdb() # this is explicitly called to initially populate cache thread = MyThread(stop_flag) thread.start() # started thread that will refresh cache every 30 mins # views.py import mainproject @api_view(['GET']) def get_data(request): str_param = request.GET.get('paramid') if str_param: try: paramids = [int(x) for x in str_param.split(",")] except ValueError: return JsonResponse({'Error': 'This rest end point only accept comma seperated integers'}, status=422) # using global cache to get records output_dct_lst … -

The questions depend on idProva. app.js let urlQuestoes = $('#myForm').data('urlquestoes'); var provaIdQuestao = $('#id_prova').val() console.log($('#id_prova').val()) console.log(provaIdQuestao); console.log(urlQuestoes); $('#questaoSelect').change(function() { let urlQuestoes = $('#myForm').data('urlquestoes'); let questaoIdQuestao = $(this).val(); console.log(questaoIdQuestao); $.ajax({ url: urlQuestoes, data: { questao: provaIdQuestao }, success: function(response) { $('#provaSelect').html(response); } }) }); }); base.html <head><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js" type="text/javascript"></script> </script></head> index.html <form action='/pesquisa' id="myForm" method="GET" data-urlquestoes="{% url 'questoes_choices_ajax' %}" data-urlcategorias="{% url 'categorias_choices_ajax' %}"> {% csrf_token %} <div class="card acik-renk-form"> <div class="card-body"> <div class="row"> <div class="col-md-4"> <div class="form-group"> <label for="provaSelect">Provas</label> {% render_field form.prova title="Provas" class="form-control" %} </div> </div> <div class="col-md-4"> <div class="form-group"> <label for="questaoSelect">Questões</label> <select class="form-control" name='questao' id="questaoSelect"> <option value="">---------</option> </select> </div> </div> <div class="col-md-4"> <div class="form-group"> <label for="categoriaSelect">Categoria</label> <select class="form-control" name='categoria' id="categoria"> <option value="">---------</option> {% for categoria in categorias %} <option value={{categoria.idCategoria}}>{{categoria.nomeCategoria}}</option> {% endfor %} </select> </div> </div> </div> <div class="row"> <div class="col-md-10"> <div class="form-group"> <input placeholder="Termo" type="text" name="q" class="form-control"> </div> </div> <div class="col-md-2"> <button type="submit" class="btn btn-block btn-md btn-primary pl-6 pr-6">Pesquisar questões</button> </div> </div> </div> </div> </form>
