I got a weird error. I hosted my django code on aws (with nginx). I updated some part of the code but response I get from the code is not getting updated, whatever the change I do.

Hey guys, I learning django 2.1.7. Created model Authors with a field name that is blank=False, then going to ./manage.py shell and trying to Author.objects.create(name="") and suddenly this object was created. Documentstion says "If True, the field is allowed to be blank". What am I doing wrong?

about name field can't be empty

have you makemigrations it?

try do same in admin and you will get error

also you can upgrade to 2.2 now 😊

i use manjaro, there's no updates yet, so i don't need to

its update from pypi not os package manager tho

Try to put null=False and blank=True to your field, run migrations and then try again into your Django shell

let me check it out

oh, sry

null=False is about your database schema, blank=False is about how admin app works with empty fields

Migrations for 'baseapp': baseapp/migrations/0002_auto_20190402_0711.py - Alter field name on author - Alter field title on book all migrations is OK, and i still getting authors with blank names. looks like I really need validators. thanks

just to be sure, remove null=False and add blank=False run migrations and try into django shell

still same, it creates blank authors

👍🏻👍🏻

but WHY?

https://docs.djangoproject.com/en/2.1/ref/models/fields/#blank Note that this is different than null. null is purely database-related, whereas blank is validation-related. If a field has blank=True, form validation will allow entry of an empty value. If a field has blank=False, the field will be required. you should show us your Form to fix this btw

<form action="{% url 'add' %}" method="POST"> {% csrf_token %} <label for="author">Author</label> <input type="text" name="author" id="author"><br> <label for="book">Book</label> <input type="text" name="book" id="book"><br> <input type="submit" class="button" value="Save"> </form>

add required to the <input/>
