Create Your Templates: Part 2

Yes, these are two different ways of doing the same thing, and the second one can be cleaner and more intuitive if you know the primary key of the object you want to access. Thanks for summing it up :)

Two Notes

Typo In Argument Passing: The first line of the second code block needs to read:

p1 = Project.objects.get(pk=1)

You’re passing the number 1 as a keyword argument to the get() method. That’s most likely just a typo, but I wanted to make sure no one gets confused when trying to use your code :)

Verifying Changes: Accessing the object (p1) again after calling p1.save() doesn’t tell you anything about changes to the content of your database. You are again just checking up on the p1 object you created and edited before.

If you want to verify that the data changed in the database, you’ll need to make another call to the database before, like so:

>>> p1 = Project.objects.get(pk=1)
>>> p1.technology
'django'
>>> p1.technology = 'python'
>>> p1.save()
>>> # now we fetch the database row again to see whether it changed
>>> p1_check = Project.objects.get(pk=1)
>>> p1_check.technology
'python'

>>> # now we fetch the database row again to see whether it changed
>>> p1_check = Project.objects.get(pk=1)
>>> p1_check.technology
'python'

Ok, that’s awesome to check the latest update in our database. Thanks!

after I added the second ‘project’ on the shell, I can’t connect anymore.

HI @kumimochi what is the error message that you see? Try to exit the shell and go back in again, it might solve the problem. Otherwise please give some more info on what is happening and what feedback Django is giving to you :)

Could you please provide me with a link to the list of Django shell commands and list of Django template language ?

Thanks. Alcuino

@alcuinog If you type one of Django’s built-in commands, you’ll get the list of available subcommands:

$ django-admin

Type 'django-admin help <subcommand>' for help on a specific subcommand.

Available subcommands:

[django]
    check
    compilemessages
    createcachetable
    dbshell
    diffsettings
    dumpdata
    flush
    inspectdb
    loaddata
    makemessages
    makemigrations
    (...)

To get more details, you can try the help command:

$ django-admin help shell

Alternatively, use the --help flag:

$ django-admin shell --help

The official Django documentation is pretty decent. You’ll find everything you need there, including help on the Django template language:

docs.djangoproject.com/en/3.1/ref/templates/language/

Hi Martin, . Great content. Going through the course I was wondering whether you could provide a working Portfolio project as a sample. The once that’s in the course materials section is only partially written.

The reason for asking is that I am visually impaired and therefore can only follow the audio but not the video. Piecing together certain things from the audio only is quite challenging and time consuming, e.g. ‘now we change this down here …’ only makes sense together with visual information. If I could use a finished project as reference point that would be very helpful.

thanks in advance

Hi @thomasseidling,

Thanks for your feedback. I’ll make sure Martin gets it. We have a written version of this course which might work better for you, in this instance, if you use a screen reader? This is the link to the article: realpython.com/get-started-with-django-1/

There is also downloadable source code linked in the article. I hope that helps.

Ricky

@Ricky, thanks, very useful!

Hi @thomasseidling, thanks for your feedback and thanks @Ricky for posting the article link.

I’ll definitely try to be spell out more descriptively what I’m doing on screen for my next videos. 👍
