Django how to use separate database for default authentication
I have a database created from non-django app and have defined the database connection info like below DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ.get('POSTGRES_DB'), 'USER': os.environ.get('POSTGRES_USER'), 'PASSWORD': os.environ.get('POSTGRES_PASSWORD'), 'HOST': os.environ.get('POSTGRES_HOST'), 'PORT': os.environ.get('POSTGRES_PORT'), } } Unfortunately, when I migrate the django admin related tables, they all go into the default database. I know that it is possible to declare multiple databases and separate read and write actions to different databases; however, what I would like to do is to have all the default django admin related tables to be created into another database. Say I declare a second database like below, how do I make sure that django admin related datas get migrated to the second database and also read from that when I login to django admin? DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ.get('POSTGRES_DB'), 'USER': os.environ.get('POSTGRES_USER'), 'PASSWORD': os.environ.get('POSTGRES_PASSWORD'), 'HOST': os.environ.get('POSTGRES_HOST'), 'PORT': os.environ.get('POSTGRES_PORT'), }, 'admin':{ 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ.get('ADMIN_POSTGRES_DB'), 'USER': os.environ.get('ADMIN_POSTGRES_USER'), 'PASSWORD': os.environ.get('ADMIN_POSTGRES_PASSWORD'), 'HOST': os.environ.get('ADMIN_POSTGRES_HOST'), 'PORT': os.environ.get('ADMIN_POSTGRES_PORT'), } } -
ModelMultipleChoiceFilter - Field 'id' expected a number but got 'Diner'
So I have a simple Ad model and a FilterView showing all the ads. The ads can be filtered by different tags stored in a separate model joined by a ManyToManyField. I'm using django-filter to set up a small ModelMultipleChoiceFilter and let users select different tags to filter the Ads. This is working however it uses the tag__id. I would like it to use the tag__slug field. Therefore I've added the attribute "to_field_name='slug'" but I get the following; Field 'id' expected a number but got 'diner'. The following code does work but only filters by tag__id like: /?tags=6 and I would rather see something like this; ?tags=diner models.py class Ad(models.Model): category = models.ForeignKey('Category', on_delete=models.SET_NULL, null=True) description = RichTextField() tags = models.ManyToManyField('Tag') title = models.CharField(max_length=200) slug = models.SlugField(max_length=200, null=True) class Meta: ordering = ['-title'] def __str__(self): return self.title class Tag(models.Model): name = models.CharField(max_length=200, help_text='Titel van de tag') slug = models.SlugField(max_length=200, null=True) def __str__(self): return self.name filters.py from django import forms from discovery.grid.models import Ad, Tag import django_filters class AdFilter(django_filters.FilterSet): tags = django_filters.ModelMultipleChoiceFilter( # to_field_name='slug', queryset=Tag.objects.all(), widget=forms.CheckboxSelectMultiple) class Meta: model = Ad fields = [ 'tags' ] How can I achieve filtering based on the model name or slug instead of the … -

Django: How to get form (or request) objects on TemplateView
I’ve built a web application with Django. On the way, a question raised, which is how does the requests getting from Formview (and Form) are passed to other vIew such as TemplateView. Following are the process steps. User enter values (requests) on the page. The request value are NOT saved on any model. The request values are calculated with the prediction algorithm (sort of machine learning) coding in app.py TemplateView receive the calculated values and display it And, following are my scripts form.py class ValueForm(forms.Form): value1=forms.Integer(label='value1', widget=forms.TextInput( attrs={'placeholder':'value1','required':True})) value2=forms.IntegerField(label='value2', widget=forms.TextInput( attrs={'placeholder':'value2','required':True})) value3=forms.Integerield(label='value3', widget=forms.TextInput( attrs={'placeholder':'value3','required':True})) def clean(self): v1=self.cleaned_data.get('value1') v2=self.cleaned_data.get('value2') v3=self.cleaned_data.get('value3') if v1==None or v2==None or v3==None: raise form.ValidationError('Sure the enter of Value') view.py for inputing the value class ValueEnterView(FormView): template_name='mysite/value_enter.html' form_class=ValueForm success_url=reverse_lazy('mysite:Prediction') #transfer to PredictionDisplayView def form_valid (self, form): form.clean() return super().form_valid(form) apps.py def Prediction(v1,v2,v3): .... .... return predicted_value view.py for displaying the prediction result import app class PredictionDisplayView (TemplateVIew): template_name='mysite/prediction.html' def post(self, request): # I want to get the requests entered in the ValueEnterView. #But the following script does not work form=ValueForm(request.POST) if form.is_valid(): v1=form.cleaned_data['value1'] v2=form.cleaned_data['value2'] v3=form.cleaned_data['value3'] return v1,v2,v3 def calculation(self): v1,v2,v3=self.post() return Prediction(v1,v2,v3) #function of apps.py def get_context_data(self,**kwargs): context=super().get_context_data(**kwargs) prediction_value=self.calculation() context['prediction']=prediction_value return context I think it might be better … -

Show the value of the fields of a model as it's stored in the database in Django
I have a Django view that exports a model into a CSV file, but I need to show the values of the fields as they are stored in the database (postgresql), for example, 't' instead of 'True', the dates the correspondent format, etc. So, as far as I see it, I have 3 options: Somehow showing the values in the way they're stored (what I'm asking here) Converting each field that has differences (I hope I don't have to do this) Making the queries directly in psql, save the result to a CSV, and return that. I wouldn't now how to do this in Django without the ORM converting the values. Please don't ask why I'm doing this. Thanks! -

How to make realtime commenting system?
hope you all are doing well.I had to make a commenting system and with reply on it and it had to be ajax supported also with pagination so you could click on more to see more comments.So I made it from scratch but as I move I am deciding to make it realtime so every guys who is on a post can see the comment that the other guy made.But I am continuiously stuck on this part.The old commenting system was like this. WHEN A USER MAKES A COMMENT. THE AJAX FETCHS THE FIRST PAGE COMMENTING API AGAIN AND THEN REDISPLAY IT BY JQUERY HANDLING THE DATA. So it worked fine but in realtime commenting it will break because suppose there are two different user's interacting with a same post and one guy is clicked the more and is seeing the next comments.But suddenly the first user comments so if the channels will be a post that means the comments will refreshed and fetched on all the user's listening to it. This is the best way I could possibly explain it.Now my question is how can I make a realtime communication like Facebook where people interact and one change that … -

Django Formset returns INAVLID despite having valid data

Update canvas element on form submit - Django
I'm trying to update an HTML canvas element on form submission with Django. I have my views.py that renders the index.html page with the processed data in JSON. return render(request, 'index.html', {'form': form, 'data': mark_safe(json.dumps(data))}) This render method is inside of an if request.method == 'POST', so essentially what's happening is it's sending the data through context to the HTML and JavaScript appropriately, however, I need canvas updates when I use the "submit" button. $('#form').submit(function() { /* all of my canvas logic */ }); Momentarily, the canvas will show the sign before the Django page is refreshed, and then reset to a blank canvas. Presumably this is because nothing in views.py explicitly tells the index.html to have a new canvas on the page with data, but I can't seem to find any information or docs on this. Furthermore: Python tkinter or other GUI libraries don't really apply here. I can only change and update the canvas through JavaScript. I can't pass a whole HTML canvas element as context through the view. e.preventDefault(); would cancel the whole submission; so if an input in the form changes, the POSTed data will not update, and in result, the drawn shapes on the canvas … -
django - modelforms and react - DRY
I'm adding React to my django web app and I'm not sure how to proceed with forms. In pure django, you can just render a form with {{my_form.as_p}} and this will create inputs for all the fields with the correct input type. If you use ModelForm, you don't even need to create a definition for the fields because it will just take it from the django model definition, keeping the DRY principle very nicely. With React I understand that it's best to give the data as json and let React take care of rendering and not use django template rendering. But with forms, this means that I have to write all the form fields by hand. Not only this is much more effort, but also it is breaking the DRY principle because I have to have two definitions of the same thing in two separate places that I need to keep in sync. Is there any library/best practice for this? Is there any way to create a json with the form definition as well as the data, and some way to render this in react without having to manually write all the fields? -
Python convert list of strings to zip archive of files

Docker so slow while installing pip requirements
I am trying to implement a docker for a dummy local Django project. I am using docker-compose as a tool for defining and running multiple containers. Here I tried to containerize the Django-web-app and PostgreSQL two services.
