Filtering Django Databases - database

Question

I am learning Django and am trying to filter names based off the database table: power_id. Is there anyway to filter based off power_id, or any variable in a database? Here is what I have so far. Note, I am using Twitter-Bootstrap
This is the Team View
<div class="accordion-inner">
<ul>
{% if User.object.power_id == 1 %}
<li>
<a href="#">
{{ user }}
</a>
</li>
{% endif %}
</ul>
</div>
Lets say, 1 is an Admin.
Here is my views.py:
# Home view
class home(generic.ListView):
template_name = 'users/home.html'
context_object_name = 'User_list'
context_object_name2 = 'Power_list'
def get_queryset(self):
return User.objects.order_by('username')
# Team view
class team(generic.ListView):
template_name = 'users/team.html'
context_object_name = 'User_list'
def get_queryset(self):
return User.objects.order_by('username')
context_object_name2 = 'Power_list'
def in_catagory(User, Admin):
return things.filter(Admin=Admin)

Answer 1

From what I can see, you have passed in a model that you have created called User. Now, I do not know if this is a model that you have actually created or if you are using django.contrib.auth.models.User. But, this is an attempt to show you how to work with views in django.
from django.views.generic import View
from django.shortcuts import render
from .models import User
class TeamView(View):
def get(self, request):
Users = User.objects.filter(power_id='123')
return render(request, 'something.html', {'Users': Users, })
What I've done here may look intimidating, but is actually quite simple. From what I can understand, you have a bunch of users, with an property called power_id. And you want to get that, you need to filter all your users for the users with the power_id that you want.
That is what the first line after the get function call does. the get function call is here because when you send a request to a page, like www.google.com, you are sending a get request.
Now, the render function is a shortcut function. What it does is this: first parameter is always request, the second parameter is the html file that you want it to render, and the third parameter is the information you are sending which is a dictionary.
Now coming to your template. You can simply loop through all your users, like so:
<div class="accordion-inner">
<ul>
{% for user in Users %}
<li>
<a href="#">
{{ user }}
</a>
</li>
{% endfor %}
</ul>
</div>

You can override the get_context_data method to add that other variable.
class TeamView(ListView):
template_name = 'users/team.html'
context_object_name = 'User_list'
model = User # You never set the model
def get_queryset(self):
return super('TeamView', self).get_queryset().order_by('username') # call the parent function
def get_context_data(self, *args, **kwargs):
context = super('TeamView', self).get_context_data(*args, **kwargs)
context['Power_list'] = self.get_queryset().filter(power_id=1)
return context
Now you also have a context variable Power_list with all of the users that have power_id == 1 that you can iterate over
<div class="accordion-inner">
<ul>
{% for user in Power_list %}
<li>
<a href="#">
{{ user }}
</a>
</li>
{% endfor %}
</ul>
</div>

I have found the answer to my own question. Turns out, it was much simpler than I thought it was. What I needed was to re-arrange the code, along with getting variables right.
<div class="accordion-inner">
<ul>
{% for name in User_list %}
{% if name.power_id == 1 %}
{{ name }}<br />
{% endif %}
{% endfor %}
</ul>
</div>
The views.py file didn't need to be edited at all.
