Django - "warning" messages in class-based views not existing?
Im in Django and I'm trying to flash a "warning" message in a class-based view. But it seems like it's only possible to create "success" messages. The module django.contrib.messages.views only have the function SuccessMessageMixin, so there doesn't seem to be any equivalent to other types of messages. Been looking through the documentations but can't find any relevant info. -

docker-compose cannot wait for mysql database
I am having real problems trying to get a docker-compose script to initiate a mysql database and a Django project, but get the Django project to wait until the mysql database is ready. I have two files, a Dockerfile and a docker-compose.yml, which I have copied below. When I run the docker-compose.yml, and check the logs of the web container, it says that it cannot connect to the database mydb. However the second time that I run it (without clearing the containers and images) it connects properly and the Django app works. I have spent a whole day trying a number of things such as scripts, health checks etc, but I cannot get it to work.

How do I set up a django website with basic backend on Direct Admin?
I am new to website deployment. I have a website with basic backend functionality for sending emails in django. I have purchased a basic DirectAdmin Web Control panel for hosting my website. I was able to set it up for static files of HTML by just simply uploading the files. But how do I go about for dynamic websites, i.e with backend functionality? Do I have to set up an Apache server or so and where do I configure the settings? The Direct Admin dashboard shows options in the GUI such as Apache handlers, MyPHP Admin etc but I am lacking the understanding on how to utilise these features. How do I possibly set up the servers and install the requirements and get it running? Please point me towards good resources for the same as I am absolutely lost. -
Django Making a Dynamic Form
I have a model called forms which can be edited from the admin panel with a list of fields lets say text1, text2, text3, image1, image2, image3. The admin can do in and input values for those lets say text1='First Name', text2='Last Name', text3='Email', image1='Logo', image2='', image3=''. Then I have another model named automation with fields the same fields but the values are what it corresponds to (so in the Form model they are all CharField but in Automation model they have the corresponding field CharField, ImageField, FileField, etc). The goal is to render a form that only displays the fields that actually have a value in Form and that value is the label for the form. So for the example above you would get a form like so: First Name: Last Name: Email: Logo: And the image 2 and image 3 are not rendered because there is no value for those in the Form model. I was able to get this working with the code below: forms.py file def get_automation_form(data): class AutomationForm(forms.ModelForm): class Meta: model = Automation fields = data[0] labels = data[1] return AutomationForm views.py file @login_required def form(request): if request.method == 'GET': nickname = request.GET.get('nickname') elif request.method … -

Is it possible in Django model to update a manually created primary key field using a calculated value during save()
IMPORTANT: NOT FOR Dorks. Dorks please excuse and leave this question alone. Now the question: Is it possible in Django to update the manually created primary key field of a model with a predetermined / calculated value during save()? In the following model, for example: class Port_Berthing(models.Model): doc_number = models.PositiveIntegerField(primary_key=True, unique=True, default=1000, ...) created_on = models.DateField(default=timezone.now, verbose_name='Created on') effective_date = models.DateField(verbose_name='Effective From') berthing_rate = models.DecimalField(max_digits=5, decimal_places=2, ...) will it be possible for me to .get the last doc_number value, increment it by 1 and insert the calculated value in the primary key field doc_number for the new record. And if it is possible, can we do this in the model's save() method? -
Dynamic File Paths with Django 3.x and Graph API
I am complete noob to django and using api's. In the process of doing some research I need to look through a bunch of files to extract some meta data. Originally I planned to copy the data down from onedrive and go through the hassle of deploying a server to expose the data. However the data is currently stored on onedrive, and thought it would be easier to access it with a web app/ console application. I went through the process of creating the sample django/python sample application and am able to run that, and figured out the correct permissions to access the root directory, but am stuck on how to go from that to being able to traverse folders and read/download the interesting files. The option I would like at the moment would be to have employ a file navigation. I saw another example from a long time ago with django, but I am having a hard time following it. Ideally I could make a request to the root drive, get the children and render a page with the list of files and folders with url links to the folder contents. clicking the file would render the meta data … -
