Doesn't django implement Content Security Policy by default?
In a RoR project I had <%= csp_meta_tag %> in the main html file. I was trying to build a conceptual app in Django with the knowledge I had at RoR, but when searching for Django Content Security Policy, only a extension appears (https://django-csp.readthedocs.io/en/latest/). There is no documentation regarding the topic so, is it possible that Django does not solve this common security issue by default? Also, I only found this SO question about this. -
How can I use Wagtail Forms for a Headless CMS? ( without Template )
According to the documentation, Wagtail API is read-only ( POST Method not allowed ). Hence, the only way to use Forms from the Sidebar Menu is using Templates, so the client is capable of making post requests against the API internaly. But that´s not headless. To be headless the API must be capable of receiving form data by providing a URL. Wagtail Docs - API "The Wagtail API module exposes a public, read only, JSON-formatted API which can be used by external clients (such as a mobile app) or the site’s frontend." ... At this point I´m not having the slightest clue, that means at a last resort I have to rethink my stack, although so far I have been very satisfied with Wagtail as headless CMS together with Nuxt as Client. Any ideas to avoid this measure would be much apprechiated. -
POST 400 Bad Request in React/Axios/Django
I'm building a website with React, with a Django backend. I have a button that when clicked runs the following function (I want to be able to send post requests from an AuthContext to be able to share the context with all my components): async function handleLogIn(e) { e.preventDefault(); const data = { email: "nultero", password: "password123", }; const headers = { "Content-Type": "application/json" }; const api = axios.create({ baseURL: "http://localhost:8000", }); try { const { resp } = await api.post("users/token/", data, { headers: headers, }); localStorage.setItem("@ezbps:JWToken", resp); console.log(resp.data); } catch (err) { console.error(err); } } Here are the console errors I get: POST http://localhost:8000/users/token/ 400 (Bad Request) dispatchXhrRequest @ xhr.js:177 xhrAdapter @ xhr.js:13 dispatchRequest @ dispatchRequest.js:52 Promise.then (async) request @ Axios.js:61 Axios.<computed> @ Axios.js:87 wrap @ bind.js:9 handleLogIn @ index.js:43 callCallback @ react-dom.development.js:188 invokeGuardedCallbackDev @ react-dom.development.js:237 invokeGuardedCallback @ react-dom.development.js:292 invokeGuardedCallbackAndCatchFirstError @ react-dom.development.js:306 executeDispatch @ react-dom.development.js:389 executeDispatchesInOrder @ react-dom.development.js:414 executeDispatchesAndRelease @ react-dom.development.js:3278 executeDispatchesAndReleaseTopLevel @ react-dom.development.js:3287 forEachAccumulated @ react-dom.development.js:3259 runEventsInBatch @ react-dom.development.js:3304 runExtractedPluginEventsInBatch @ react-dom.development.js:3514 handleTopLevel @ react-dom.development.js:3558 batchedEventUpdates$1 @ react-dom.development.js:21871 batchedEventUpdates @ react-dom.development.js:795 dispatchEventForLegacyPluginEventSystem @ react-dom.development.js:3568 attemptToDispatchEvent @ react-dom.development.js:4267 dispatchEvent @ react-dom.development.js:4189 unstable_runWithPriority @ scheduler.development.js:653 runWithPriority$1 @ react-dom.development.js:11039 discreteUpdates$1 @ react-dom.development.js:21887 discreteUpdates @ react-dom.development.js:806 dispatchDiscreteEvent @ react-dom.development.js:4168 Error: Request failed … -
generate barcodes with crud information in python
This is a control access for builders with double check to enter the work area, first with the official ID then the barcode to verify the information. I already built a crud using Python, Django and Postgresql without the barcode because still don't know how to connect the data with the EAN code. How can I connect this information with the codebar to show on modal window? -
Getting ValuError: Field 'id' expected a number but got a html
I am a newcomer, about 10 days into a self-taught Django, and I am building a Django (v3.2) app. The main view in the app is a list of countries (view: CountryListView, template: countries_view.html). When I click on a country in that list, a detail view is brought up to see detailed country data (CountryDetailView and country_detail.html). In CountryDetailView, there are navigation buttons: either back to CountryListView, or 'Edit', which shall bring the user to CountryEditView, where the country parameters can be changed & saved. However, when I click on 'Edit', I get the following error: Request Method: GET Request URL: http://127.0.0.1:8000/manage_countries/countries/country_edit.html/ Django Version: 3.2.4 Exception Type: ValueError Exception Value: Field 'id' expected a number but got 'country_edit.html' I am guessing this might to do something with values returned (or rather expected but not returned) from CountryDetailView, but what they are? And how to make CountryDetailView to return the object id? (I am using plain integer id's in my model) views.py class CountryListView(LoginRequiredMixin, ListView): model = Countries context_object_name = 'countries_list' template_name = 'manage_countries/countries_view.html' class CountryDetailView(LoginRequiredMixin, DetailView): model = Countries template_name = 'manage_countries/country_detail.html' class CountryEditView(LoginRequiredMixin, UpdateView): model = Countries template_name = 'manage_countries/country_edit.html' success_url = reverse_lazy('manage_countries:countries_view') urls.py path('', CountryListView.as_view(),name='countries_view'), path('countries/<pk>/', CountryDetailView.as_view(), name='country-detail'), … -
Django Migrations not updating Heroku PostgreSQL database
I've been stuck on an issue for a while where I have a model that I've created locally (class User(AbstractUser)), ran "python manage.py makemigrations" and "python manage.py migrate", which also works and interacts correctly with the django server when run locally. When I push this to heroku however, I receive an error response to certain api requests which essentially say "relation "app_user" does not exist". I assumed this was because somehow the postgreSQL db didn't receive the migrations when the app was deployed to heroku. After logging into the db I noticed that it had a few other tables, including "auth_user" (I assume this is a default django table), but not "app_user". I have done "heroku run bash" and "python manage.py migrate" in an attempt to migrate the changes to the postgreSQL db, but this doesn't have any effect. I'm not sure if this will be useful but the postgreSQL server I'm using is the standard Heroku Postgres Hobby Dev add-on. My questions are: Should running "python manage.py migrate" on heroku update the postgreSQL database? If so, how does this work? Given that the migrations are all on heroku, how can I manually update the postgreSQL with the migrations? -
Django Add default value to model field having the value of another field
I want to add a field to my django model and I want its default value to be equal to the primarykey value (id), but I want it to apply to all already existing records in my database. class ModelB(models.Model): id= models.IntegerField() index = models.IntegerField(default=" i want something here to get id value") I found previous questions covering this but the answers only give a solution where you have to add a method that adds the value on save. In my case I want this value to be applied to previously saved records also. Please if you have an idea I'd appreciate your help, thanks. -
Django not saving ModelForm data
I've looked at other questions but I can't find the root of my problem. I'm making a checkout view which should save an address with a customer. It creates an Address object, with a customer referenced but isn't saving any of the form data.

How to configure the Index.fcgi path?
I'm finishing with setting up my Django project on my hosting using ssh. i am following an article to be able to install it correctly. Some of the steps I had to follow are as follows: Create the . htaccess file with the settings of the FCGI Handler and redirection to the index.fcgi file that will be created: AddHandler fcgid-script .fcgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.fcgi/$1 [QSA,L] and Create the index.fcgi file in the root of your application with the following content: #!/home/CONTA/.virtualenv/bin/python import os, sys from flup.server.fcgi import WSGIServer from django.core.wsgi import get_wsgi_application sys.path.insert(0, "/home/CUENTA/mydjango") os.environ['DJANGO_SETTINGS_MODULE'] = "mydjango.settings" WSGIServer(get_wsgi_application()).run() Already having those two files in the public html and opting the permissions to the index.fcgi using chmod 0755 At the time of me see if it is running using the following command ./index.fcgi, tells me that there is no file or directory. Which leads me to assume that I need to set a path within the index.fcgi or . htaccess but I do not know what I need to change since in the article only comes that. Thank you -

Django: How to clean a model with inlines?
I created an app that implements a quiz. I got a glitch, however, when I tried to clean a model. models.py class Question(models.Model): def clean(self): options = Option.objects.filter(question=self) correct = 0 for option in options: option.save() print(option) if option.correct == True: correct += 1 print(correct) if correct > 1: raise ValidationError(_('Please only input 1 correct answer.')) if correct <= 0: raise ValidationError(_('Please input 1 correct answer.')) #limit questions if options.count() > 4: raise ValidationError(_('Only 4 maximum amount of options!')) class Option(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE, related_name="question") correct = models.BooleanField(default=False, verbose_name="Correct?") The problem I figured is that when the site tries to save each question, it saves each model Question before saving each Option. -

What tech stack to use for a project using multiple API I/O processes in background?
I am unable to decide what technology would be better to use for my project. The project has the following purpose. I will be using a 3rd party API service for 2 major purpose Creating, updating, and deleting events. Fetching past changes made. So at any point in time, I can start a new service, that will be creating new events for me by loading data from an excel file and, this service would now be running in the background (also having the functionality to pause/stop the service at any time). Multiple such services of creation from different excel files will run simultaneously in the background. Similar to the above service, I will create a fetch service to fetch data in regular intervals indefinitely and dump that data in an excel file. Again, this service will also run in the background and can be paused/stopped. Multiple such services will also run in the background. Now, for the project, I have 2 questions regarding what Tech Stack I should use. Should I go for a Django based web app or should I go for NodeJs based webapp? If I choose Django, what are the ways I can achieve concurrency and parallelism? … -

disabling/enabling a field in Django form depending on a value of another field in the same form
Asking a beginner's question. I have a ModelForm object with a quite large number of fields. I want some of these fields to assume to be editable or not editable, based on a value of some other field (in the same form): For example: split_words = forms.BooleanField() split_words_min_length = forms.IntegerField(min_value=1,max_value=140) I would like split_words_min_length field to be disabled (or not displayed), if split_words is set to False (unchecked).

Displaying one value and sending another to backend with HTML <select> and <option> tags
I'm making a note-taking web app. The rich text editor includes a drop-down menu containing the names of each of the user's notebooks, so that the user can choose where the note will go. So far so good. The problem is that, in theory, the user could name two notebooks the same thing. So when the user chooses a notebook, the frontend ultimately needs to send the ID slug associated with that specific notebook to the backend, so that Django can choose which notebook to associate the note with without ambiguity. The problem is that I don't know how to make the HTML <select> and <option> tags do what I want them to. I tried putting in one value between the HTML tags (so that it's displayed) and passing the ID as the tag's value attribute, but this doesn't seem to work: setNotebooks(notebookList.map(item => { return ( <option value={item.notebook_id}> {item.name} </option> ); When I set notebooks in the way I showed above, it comes back as undefined. In the example, notebookList is an array of objects containing each notebook's attributes.

I am developing an agency web app with django templates & static files. But I am having trouble with loading static files on pages other than index. Here's my folder heirarchy. Again, I am having no problems loading static files on my index page. Here's code of my additional page services.html (one I am trying to load static files on): {% extends 'base.html' %} {% load static %} {% block content %} ... ... ... {% endblock %} My base.html is working totally fine with the homepage index.html. I've included this on my settings.py STATIC_URL = '/static/' STATIC_ROOT = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, 'static'), ) STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') And, my views.py and urls.py files are working fine too. Also my CSS file is correctly linked to the services.html file. I can tell this from the inspection. Here's the error list shown on inspection. Help will be appreciated. Thank you.
