Pull Data From The Database - Django Databases #3
HTML-код
- Опубликовано: 22 авг 2024
- In this video I'll show you how to pull data from the database and output it onto a webpage with Python and Django.
In the last video we created our database class and pushed our migration into the database. We also added some data to the database thru the Django admin area. In this video I'll show you how incredibly easy it is to pull that data back out of the database and output it onto the screen.

John, you are a godsend. Thank you so much for this series, for someone like me who knows Python but has no experience with databases this is just incredibly helpful. Most tutorials just skim right past the topics you cover here leaving you with the knowledge of “copy this code and paste it into your file.” Thanks again,

Glad you enjoyed it!

Thanks
50 Likes and no dislike that's awesome
agreed :-)
I followed the video and used it in my project, but in the end it did not work.. the screen was all blank.. Do you know what could be the problem?
------------------------------------------
My model:
from django.db import models
class Posicao(models.Model):
nome = models.CharField('Posição', max_length=5)
descricao = models.TextField('Descrição', max_length=1000)
secao = models.ForeignKey(Secao, blank=False, null=False, on_delete=models.CASCADE)
capitulo = models.ForeignKey(Capitulo, blank=False, null=False, on_delete=models.CASCADE)
def __str__(self):
return self.nome
-------------------------------------------
My view:
from django.shortcuts import render
from .models import Posicao
def consultar_123(request):
consultar_abc = Posicao.objects.all()
return render(request, 'consulta_ncm.html', {'all' : consultar_abc})
-----------------------------------
My urls:
from django.urls import path
from django.views.generic import TemplateView
urlpatterns = [
path('consulta_ncm', TemplateView.as_view(template_name='consulta_ncm.html')),
------------------------------------
My html (consulta_ncm.html):
Hello World
{{all}}
-----------------------------------
The outcome:
Hello World
You didn't follow the video correctly. Try watching the video again and give it all another try
Hello jhon.is there a way to extract from a table to an other on in the same db for example if i want to to move it from table to on other one base on some conditions
Sure, but too complicated to explain in a comnent
@@Codemycom thnks u
Can you make a video for model choice values for a drop down list please
Not sure what you mean
@@Codemycom sorry, that was vague. I meant a query set for users to select options but the voices will be coming from the data base. Also Thank you very much for your video- you are the best my guy. New York loves you Brother
I want to pull the records of database and store it in an Excel sheet...is this possible sir??
Sure
@@Codemycom Done sir
Hello John, Please how do I add an additional column to an existing database thru models.py? Thank you
I have a django blog playlist on this channel that will show you that. Essentially just add the new thing to your models.py file, then make a migration and push the migration as normal.
@@Codemycom Thanks so much sir.
the data is not printed on the page
What did you do differently from the video?
