Rendering specific fields multiple times in Django model form
I am learning django and have encountered a challenge. I have a model in which I want to render specific fields multiple times depending on how much the user wants to fill in, while rest of the model fields remain the same. Below is an example model. I want to render the model form in such a way that the fields 'building' and 'tour_date' can be repeated as many times as required while 'client_name' and 'client_email' remain the same. I looked at inlineformset_factory but I think it needs a parent model. I don't think it serves my purpose although I would love to have some of its features like 'extra' and 'can_delete'. The saved records have to be saved as new rows in the 'Tour' table. Another challenge I am facing with the below example is that the 'building' field has to be a drop-down. I have provided the forms.py below for reference. How can I write a view for such a requirement in Django 3.0? Requesting some assistance and guidance. models.py: class Tour(models.Model): name = models.CharField(max_length=100) email = models.EmailField(max_length=100) building = models.CharField(max_length=255) tour_date = models.DateField() ... class Meta: managed = True unique_together = ('name', 'building') forms.py: class TourForm(forms.ModelForm): building … -

Which is the best way to make backend for a small website? [closed]
Good afternoon! I'm currently working on a website, and front end is mostly done, now i want to implement authorization form. I got curious which way is better, i want to make a a back end system on a virtual machine using ubuntu. I just thinking which environment is better for simple website. I'm thinking of nodejs since i was using it for some API's or to use Python + Django. MongoDB as a database. Is there any resources that i can look into how to connect back end with front end when back end on virtual machine? And is it good way of doing it? Or better to do back-end internal?
