Django不会从表单（非管理员）写入数据库

Question

Hi guys I have a little problem with Django 1.9. the class CreateView me not recorded in the database , the funny thing is that I did not throw any error, however added a code that validates form and asked to make a print (" Bad" ) console if the form is invalid. Every time sending the form (using POST) does not record anything and console, thanks to the setting you did, I printed 'bad ' . Now the problem is that the form is invalid, but can not find what is . Any ideas?

forms.py

It renders the template as well, even with the css and js .

You have instantiated a ModelForm without reference to the model. Perhaps you should be using a plain form like so:

from django import forms

class MyForm(forms.Form):
    # define fields

If you use a ModelForm you have to specify the model in a Meta internal class like so:

from . import models
from django import forms

class MyForm(forms.ModelForm):
  class Meta:
      model = models.MyModel
      fields = ['field1', 'field2',]

Check out https://docs.djangoproject.com/en/1.9/topics/forms/modelforms/ and https://docs.djangoproject.com/en/1.9/ref/forms/api/ for more details. I would strongly recommend mastering the docs as they are world class.
