I’m just starting my adventure with Django. I wrote a small application in which, of course, there is a form that collects data from the user. This form in the standard version of Django doesn’t look nice. I found information about crispy-form on the Internet and added it to my project.
I managed to create a form that I like, but there is a problem. I cannot save the data retrieved from the form to the database. Previously, when I had a Django form, in the views.py file, the function handling this form saved the retrieved data to the database. Now that it’s crispy-form I don’t want to save.
My knowledge is too little to be able to do it, hence my request to you for help.
Can you take a look at the codes below and tell me what I’m doing wrong?
