I believe that by 'knowledge' it's not only Django and Flask but HTML and CSS. Yes, you can call yourself a Backend developer. You'll have to prove it with projects though.

Can I call myself a BACKEND developer if I have knowledge of Django or flask alone.

I think the OneToOne relationship is a better approach. One thing I've learnt about OOP is the SOLID principle. Responsibilities should be divided across classes and models. Leave the User model to handle core Django features while you have a different model that provides other functionalities for a user. So many things could go wrong with Abstract User.

I understand you perfectly but there are some scenarios where AbstractUser is a better approach as well and based on the example I made earlier, it is a better approach, when you are writing permissions, it is a better approach to inherit from AbstractBaseUser when you know what you are doing. Using User model directly is very tho because if things go wrong then it can be fatal.

Even the Django documentation recommends you start every project inheriting from AbstractUser.

E get why.

If there is, it will be few because most request for PHP, C# e.t.c but foreign companies do use django

Hello guys i am building a django web app, and i run into this error..... NoReverseMatch at /groups/posts/in/python/
Reverse for 'user-posts' with keyword arguments '{'username': ''}' not found. 1 pattern(s) tried: ['user/(?P<username>[^/]+)$']

below is the sample of the template HTML page

<h3 class="mr-5"><a href="{% url 'posts:user-posts' username=post.user.username %}">@{{ post.user.username }}</a></h3>
<div class="media-body">
<strong>{{ post.user.username }}</strong>
<h5>{{ post.message_html|safe }}</h5>
<time class="time"><a href="{% url 'posts:post-detail' username=post.user.username pk=post.pk %}">{{ post.created_at }}</a></time>
{% if post.group %}
<span class="group-name">in <a href="#">{{ post.group.name }}</a></span>
{% endif %}
</h5>


below also is a sample of the app urls.py code

path('', PostListView.as_view(), name="blog-home"wink,
path('user/<str:username>', UserPostListView.as_view(), name="user-posts"wink,
path('post/<int:pk>/', PostDetailView.as_view(), name="post-detail"wink,


And here is my views.py code that controls the username

class UserPostListView(ListView):
model = Post
template_name = 'blog/user_posts.html'
context_object_name = 'posts'
paginate_by = 6

def get_queryset(self):
user = get_object_or_404(User, username=self.kwargs.get('username'))
return Post.objects.filter(author=user).order_by('-date_posted')


How can I fix this, it seems the "username" is empty hence not matching the regex in urls.py?

In your urls. py, did you add any app_name 'posts' or not, of you have not, add it and try again

Since you are will be calling it in the html i.e post:name of url therefore you must add create the app name. Sorry which book or tutorial video are are you using to learn?

it is mandatory to add it because if you have more than one app in your django project, and the URL name is the same, then the URL need to match up with URL name you provide, that's why it is important to prefix it an app_name. I wish I could explain much better.

In my groups app urls.py I did create an app name groups, so I don't know why there should be a clash, cos when I am referencing groups component using template tag I always use "groups:group_detail"... I removed app name from posts because it was giving me "namespace" error.
I am using Corey Shafer tutorial on Django for the development of the web app, but I decided to add groups to the web app to make it robust

django tip:

insert import ipdb; ipdb.set_trace() at the end of the file django identifies as the source of the error,
reload the page and your browser will pause(continue loading not stopping),
then go to your console. an interactive debugger will be set up, just type a variable name and hit enter, the value will be displayed.

Good for debugging

I wanted to say that too.

Nairaland has the advantage of being open, so there is continuous flow of knowledge unlike whatsapp and telegram.

I understand you bro but dont get me wrong here .What I am saying is that we can develop a community of django devs where django related problems are resolved just like a mini stackoverflow etc.... for NL members. We don't have to use whatsapp. Just an opinion.

Bosses them, abeg wetin be 'instance', can't find anything in the documentation about it

Instance there means that, when the user wants to update their profile, their previous information would be filled automatically.

It's like creating an instance of what was there, before you edit it.

TIP: Check the meaning of instance in the dictionary for better understanding

In any OOP language, when you create a class, then you can create a variable name to instantiate the class e.g

Class Dog :
Def ___init____(self, name, age):
self. name =name
self. age = age

So here you can instantiate the class dog like this

dog1 = Dog('bingo', 5)
dog2 = Dog('linzy', 2)

So dog1 and dog2 are both instance of the dog class. You can read more on classes on python to understand better.

OOP in python is quite confusing. Starting with "self" instead of "this" to the weird init constructor.

I get what instance is, just didn't understand how it could be a property of a form. It's clear now though.

Thanks for the help

It's nothing complex, just ordering of url patterns, I already got some insight as to how to do it tho.

the editor is Acode, while I use pydroid3 terminal to run command-line comands... I don't use iOS, but I'm sure a Google search would produce results
Good evening,

I use pydroid too, I want to know if you have been able to use the pydroid terminal to perform GitHub stuffs like push, clone and co?

Haven't published my code to GitHub since my PC crashed.

I didn't even think to try.

I'll try it later tonight, and see if it works
