Problem to transfer data from Django template to vue.js app
I am trying to make Django and Vue talk. I installed Vue-Cli with Vue3. Vue app is well displayed into the Django template, but I can't transfer data (Django data but also a simple string for testing) to the vue app. App.vue <template> <h1>{{ msg }} world</h1> </template> <script> export default { name: 'App', props: { msg: { type: String, default: 'test' } } } </script> <style scoped> </style> main.js import { createApp } from 'vue' import App from './App.vue' createApp(App).mount('#app') This code shows "test world", instead of "Hello world". Thank you in advance for your help. -

Disabling and reassigning a new django token
I am planning to use "RestFrame TokenAuthentication" for django API requests. I want to give the Bearer Token to my client for accessing the API. The token needs to be disabled based on payment module. On a succesful payment, i needs to create a new token programatically and give it to the client. Is it possible to deactivate and renew with a new token when necessary ? Is it the best practice to use "RestFrame TokenAuthentication" for such a scenario ? -
Django: Create a Model from parsing a different model's field
I have a model A with several fields. One of the fields ("results") is a a dict-like string in my database (which is hardly readable for a human being). Can I create a separate Model that would basically parse that "results" field into its own fields, so I can have a separate table with fields corresponding to the keys and values from my "results" field from model A? Final goal is to make a Results table that shows all the information in a pretty and easy-to-read manner. class ModelA(models.Model): language = models.CharField(max_length=30) date = models.DateTimeField() results = models.CharField(max_length=255) This is how "results" field looks in my database (I cannot change this format): OrderedDict([('Name', 'Bob'), ('Phone', '1234567890'), ('born', '01.01.1990')]) I want to create something like this: class Results(models.Model): name = model.Charfield(max_length=100) phone= model.IntegerField() born = model.DateTimeField() What is the best way to do this? How do I take the info from the "results" field from ModelA and "put" it into the Results model? -

django settings.ABSOLUTE_URL_OVERRIDES requires the whole url to work
I'm maintaining a mezzanine/django application that has a couple of calls of get_absolute_url(). The always fail unless I put the following into my settings.py: ABSOLUTE_URL_OVERRIDES = { 'page_types.basicpage': lambda o: "http://<myHostName>:<myPort>/%s" % o.slug, 'page_types.registerdescpage': lambda o: "http://<myHostName>:<myPort>/%s" % o.slug, 'page_types.uutinen': lambda o: "http://<myHostName>:<myPort>/uutinen/%s" % o.slug, } According to django documentation this should also work ABSOLUTE_URL_OVERRIDES = { 'page_types.basicpage': lambda o: "/%s" % o.slug, 'page_types.registerdescpage': lambda o: "/%s" % o.slug, 'page_types.uutinen': lambda o: "/uutinen/%s" % o.slug, } But it doesn't.

Django-admin: show multi select field for JSONField
I have a model with a field channel (JSONField). I'm strong an array of string in db with channel. By default, a JSONField is shown as a textarea in django-admin. My goal is to somehow make channel a multi-select field that later converts to like this ["APP", "WEB"]. models.py @dataclass class ChannelTypes: WEB: str = 'WEB' APP: str = 'APP' class DiscountRule(models.Model): ... channel = models.JSONField(null=False, blank=False, default=list(astuple(ChannelTypes()))) My Approach: In forms.py, add custom fields (boolean) that only show up in admin form and are not stored in db. Something like this: class RuleAdminForm(forms.ModelForm): WEB = forms.BooleanField(required=False) APP = forms.BooleanField(required=False) Similarly, admin.py will populate the custom fields like this: def get_form(self, request, obj=None, *args, **kwargs): form = super(BaseDiscountRuleAdmin, self).get_form(request, *args, **kwargs) for i in obj.channel: form.base_fields[i].initial = True return form But this causes a problem that the custom field value persists after updating 1-2 times due to using base_fields[field_name].initial. Ideas for goal: Multi select option 1 -

Customize Django FilterSet: Create custom filter
I have a document table (django-tables2) and a FilterSet (django-filter) to filter it. That works fine in general. I want to create a custom ModelChoiceFilter (or ChoiceFilter) to display the elements in a two level hierarchy (a tree with parent nodes and one level of children): + Category 1 + Subcategory 1.1 + Subcategory 1.2 + Category 2 + Subcategory 2.1 + Subcategory 2.2 There is no need to expand and collapse the tree, i just want to show them ordered by category and rendered a little differently if they are first or second level. There are never more than two levels present and each top level component has at least one child. My current FilterSet looks like this: class DocumentFilter(FilterSet): title_name = CharFilter(lookup_expr='icontains') place_name = CharFilter(lookup_expr='icontains') source_type = ModelChoiceFilter(queryset=SourceType.objects.all().order_by('type_name')) doc_start_date = DateFromToRangeFilter() class Meta: model = Document fields = ['title_name', 'source_type', 'place_name', 'doc_start_date'] My model for the SourceType is as follows: class SourceType(models.Model): type_name = models.CharField(verbose_name="archivalienart", max_length=50,) parent_type = models.ForeignKey('self', verbose_name="übergeordnete Archivalienart", on_delete=models.CASCADE, null=True, blank=True, related_name="child_type",) The filter form template is as follows: {% load bootstrap4 %} <form action="{{ request.path }}" method="get" class="form form-inline"> <i class="fas fa-filter"></i>&nbsp; {% bootstrap_form filter.form layout='inline' form_group_class='my-small-form' %} &nbsp; {% bootstrap_button '<i class="fas fa-filter"></i>' … -
Django Page error takes no argument when click on link to it
I have been struggling with one of my pages in django. Basically I a making a graph (nodes and edges) where you can add remove nodes through forms. I have a graph model (GraphDetail) which requires nodes, and I am building the node form (GraphCreateNode) that adds nodes to the graph. However the link does not work. It says that GraphCreateNode does not take any arguments. Now CreateGraphNode needs the id of the graph it is going to be added to, whether that is sent via the url or stored and accessed in session I do not have a preference. Right now I am trying via the url. And as said I get an error, and I cannot see where I need to fix it, which is why I am asking all of you. Error Message: TypeError at /graphs/graph/74921f18-ed5f-4759-9f0c-699a51af4307/graph_add_node/ GraphCreateNode() takes no arguments So I looked around here to see what I could find: What is a NoReverseMatch error, and how do I fix it? was quite informative but not quite enough.

Custom button in Class based UpdateView django
Problem: My UpdateView looks the same as my CreateView. I would like to change the submit button from "Check" to "Update".

Something like {% if CreateView %} Check {% else %} Update {% endif %} in the html file would be nice, but I don't know how to implement it. Thanks in advance! -
CSRF verification failed. Request aborted. only for login page
I am creating a To-Do application as my first project in django. Everything works fine when I run on local server but when I deploy it to heroku, CSRF token is not working on login page only. The app is deployed here. Issue: If we try any random or existing user on the login page, it shows CSRF verification failed BUT if we open /register endpoint i.e. Register a user on the app, it creates user and logs in to that user correctly at them time. Whole app features like adding a new task, editing a task, deleting a task works fine until I logout that user. When I come back to the login page again, I am not able to login with any user account. I've tried a lot of different methods like services in Procfile, environment variables for SECRET_KEY, providing meta tag in the main.html for csrf token using content={{ csrf_token }} but no luck.
