"CELERY_BEAT_SCHEDULER" config is not work in django settings
I set CELERY_BEAT_SCHEDULER = "django_celery_beat.schedulers:DatabaseScheduler" in my django project settings file. But It doesn't seem to work. I check the celerybeat logs and I found that the celery beat scheduler is celery.beat.PersistentScheduler. I can only set beat scheduler to "DatabaseScheduler" at the celery beat startup file (celery -A config beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler). How can I set the scheduler in django settings file ? I don't want to set the scheduler in the celery beat startup command. -

Model Instance Methods using the __str__() method
I have come across this in these Sections of the Django Documentation. I am however confused by the difference between the two. What is the difference between: (found HERE) class Person(models.Model): name = models.CharField(max_length=128) def __str__(self): return self.name and: (found HERE) class Person(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) def __str__(self): return '%s %s' % (self.first_name, self.last_name) Which one is the correct one? Note that both work interchangeably as far as I have tested -

Using Websockets with Django on Google App engine Flex
I'm currently trying to setup a Google app engine flex using a django framework with django-channels. for my current project i need a websocket, so i'm trying to reconstruct the tutorial offered on the website by Django-channels: https://channels.readthedocs.io/en/latest/tutorial/ Currently I'm stuck on adding redis to my google-app-flex instance.

How to correctly integrate mailchimp with your website?
I wanted to use Mailchimp for my a website which would basically take user's email when submitting,so I got the url from mailchimp which stands like the url below, I added the post-json and also &c=? at the end! https://xxxxxx.us3.list-manage.com/subscribe/post-json?u=b5d4f5b14088dceec18dc9ca8&amp;id=9d2643cd8e&c=? And integrated it with my jquery like this! $(".mailchimp-submit").submit(function(e){ e.preventDefault() var this_ = $(this) var successMsg = "success_message" $.ajax({ type: "GET", url: "url", data: this_.serialize(), cache : false, dataType : 'jsonp', error : function(err) {errorMsg()}, success:(data)=>{ if (data.result != "success") { errorMsg(successMsg) } else { msg.text() msg.css("color","#6610f2") } }, }) }) And built my form like this! <form class="mailchimp-submit wow fadeInUp" data-wow-delay="0.6s" method="GET" > <div class="input-group subcribes"> <input type="text" name="EMAIL" class="form-control memail" placeholder="abc@example.com" required> <button class="btn btn_submit f_size_15 f_500" type="submit">{% trans 'Get Started' %}</button> </div> </form> But I submit my email on FireFox it gives me a warning in console: The resource at “https://xxxxxxx.us3.list-manage.com/subscribe/post-json?u=b…1590645826995&EMAIL=yoneyos382%40whowlft.com&_=1590645826996” was blocked because content blocking is enabled.

Make each fieldset within the inline collapsable, not the whole inline
I wanted to know if there is any way to make the fieldsets (StackedInline items) within the Inline container collapsable.

Update serializer data in Django

DTO's in Django Python?
So I am starting to learn Django, and looking to build a Rest API with it. I am basically coming from .Net background. I know that the Python conventions are quite different than .Net's and I understand that well, but in my perspective, I see lot of redundancies and lack of standards(Solid) when developing application in Django. Here is my project hierarchy. [DjangoProject]: [Finance]: admin.py apis.py services.py test.py urls.py models.py [Users]:... apis.py -> Each API will have it's one class class ReportCreateApi(APIView): class InputSerializer(serializers.Serializer): title = serializers.CharField() description = serializers.CharField() pictures = serializers.CharField() lat = serializers.CharField() long = serializers.CharField() vote = serializers.CharField() def post(self, request): serializer = self.InputSerializer(data=request.data) serializer.is_valid(raise_exception=True) ReportService.ireport_create(**serializer.validated_data) return Response(status=status.HTTP_201_CREATED) services.api -> Services will have **kwargs as parameters class ReportService: @staticmethod def ireport_create(**report) -> Report: logger.info('Creating IReport') ireport = Report(**report) #Report is a modal btw ireport.save() return ireport Although it works for now, it doesn't look right to me. With this anyone can pass unlimited number of parameters that may not be expected by the services. What would be the best approach to pass the parameters to the service from api so that I can map it to the model when creating one inside the service? -

Adding/Exposing a port with Django to an existing Docker container
This may have a fairly simple answer here, but... I am trying to use this container: https://hub.docker.com/r/gboeing/osmnx in order to just easily handle some complex dependencies. I ran into all kinds of conda dependency issues with the library I'd like to use when just building a docker image from the continuum/anaconda container. So, I'd like to expose a port and run a Django server from inside this container. I manually installed Django and ran the server inside the container.

fetch acting differently in different places
I'm making a React + Django Integrated website. Here is the relevant snippet of my App.js in one folder and what it outputs - componentDidMount(){ fetch("/login/api/login_page") .then(response => { if (response.status > 400){ return this.setState(()=> {return {placeholder:"Something went wrong!"}; }); } return response.json(); }) .then(data=>{ this.setState(()=> { return{ data, loaded: true }; }); }); } //The rest has been omitted for brevity The link of that page itself is http://127.0.0.1:8000/loginresults/list/ and it accesses http://127.0.0.1:8000/login/api/login_page . However when I use nearly identical code in another .js file elsewhere it causes a weird error. componentDidMount() { fetch('/timetracker/api/TimeTracker/allObjects') .then(response => { if (response.status > 400) { return this.setState(() => { return { placeholder: "Something went wrong!" }; }); } return response.json(); }) This is called in http://127.0.0.1:8000/ttgui/op/ and when it tries to access it, it keeps searching a URL - http://127.0.0.1:8000/ttgui/op/timetracker/api/TimeTracker/allObjects/ whereas it should be going to http://127.0.0.1:8000/timetracker/api/TimeTracker/allObjects/ as illustrated above. Does anyone know why it's acting differently in these two different use cases? -
how do I update/delete a content in Django?
So I have a form in Django that lets users write their diary. Now I want to add edit button and delete button, but I'm having error.

Extending the `Field` class in Django
All my searching gave results for "custom fields" in Django which is not what I'm after, I'm trying to customize the Field class. The only similar question was not answered. I'm building a form in Django, and I'm trying to specify a specific icon to appear by each input field. For example, I have added a non-standard icon argument when building my form: checkin.py from django import forms class CheckInForm(forms.Form): last_name = forms.CharField( icon="fa-id-card-o" ) dob = forms.DateField( icon="fa-calendar" ) I would like to access this new icon argument from my template: checkin.html <form action="" method="post"> {% csrf_token %} <table> {% for field in form %} <label for="{{ field.name }}" class="col-4 col-form-label"> {{ field.label }} </label> <div class="col-8"> <div class="input-group"> <div class="input-group-prepend"> <div class="input-group-text"> <i class="fa {{ field.icon }}"></i> <!--- icon argument ---> </div> </div> {{ field }} </div> </div> {% endfor %} </table> <div class="form-group row"> <div class="offset-4 col-8"> <button name="submit" type="submit" class="btn btn-primary">Check In</button> </div> </div> </form> When I run this code, it of course fails with: TypeError: init() got an unexpected keyword argument 'icon' Attempted approach It seems to me this is a good case to extend some Python classes.

load of csv or json with jquery in django always brings back entire page html instead of contents of file
I've got a Django project on Win 10. I am trying to load a local json or csv file with custom jQuery. I've discovered that whenever I try to load the contents of a json or csv file, located somewhere in my /static/ directory, it always brings back the entire html page instead of the contents of the file. Doesn't matter if it is json or csv. I know by now that if there is an error, the html will come back, but I do not know how I could solve this problem at this point. function test () { fetch("admin/js/custom/codetable.json") .then(res => res.json()) .then((out) => { console.log('Output: ', out); }).catch(err => console.error(err)); } will bring back Unexpected token < in JSON at position 0 That is not a data format error, as I had previously suspected. I know the path resolves because if I intentionally foogle the path, there will be an additional 404 error. If I try this: function test2() { fetch("admin/js/custom/codetable.csv") .then(response => { if (!response.ok) { throw new Error('Network response was not ok'); } return response.blob(); }) .then(myBlob => { myImage.src = URL.createObjectURL(myBlob); }) .catch(error => { console.error('There has been a problem with your fetch operation:', … -
Field 'id' expected a number but got 'std1', how do I get the ForeignKey ID of a Model field to use in Django Form?
I have Detail Model, which have the ForeignKey of the Django's default User Model.

Still I get this error. -
