Django Add Link to Details
Details Template
The next step in our web page will be to add a Details page, where we can list more details about a specific member.
Start by creating a new template called details.html:
my_tennis_club/members/templates/details.html:
<!DOCTYPE html>
<html>
<body>
<h1>{{ mymember.firstname }} {{ mymember.lastname }}</h1>
<p>Phone: {{ mymember.phone }}</p>
<p>Member since: {{ mymember.joined_date }}</p>
<p>Back to <a href="/members">Members</a></p>
</body>
</html>Add Link in all-members Template
The list in all_members.html should be clickable,
and take you to the details page with the ID of the member you clicked on:
my_tennis_club/members/templates/all_members.html:
<!DOCTYPE html>
<html>
<body>
<h1>Members</h1>
<ul>
{% for x in mymembers %}
<li><a href="details/{{ x.id }}">{{ x.firstname }} {{ x.lastname }}</a></li>
{% endfor %}
</ul>
</body>
</html>
Create new View
Then create a new view in the views.py
file, that will deal with incoming requests to the
/details/ url:
my_tennis_club/members/views.py:
from django.http import HttpResponse
from django.template import loader
from .models import Member
def members(request):
mymembers = Member.objects.all().values()
template = loader.get_template('all_members.html')
context = {
'mymembers': mymembers,
}
return HttpResponse(template.render(context, request))
def details(request, id):
mymember = Member.objects.get(id=id)
template = loader.get_template('details.html')
context = {
'mymember': mymember,
}
return HttpResponse(template.render(context, request))The details view does the following:
- Gets the
idas an argument. - Uses the
idto locate the correct record in the Member table. - loads the
details.htmltemplate. - Creates an object containing the member.
- Sends the object to the template.
- Outputs the HTML that is rendered by the template.
Add URLs
Now we need to make sure that the /details/
url points to the correct view, with id as a parameter.
Open the urls.py file and add the details view to the
urlpatterns list:
my_tennis_club/members/urls.py:
from django.urls import path
from . import views
urlpatterns = [
path('members/', views.members, name='members'),
path('members/details/<int:id>', views.details, name='details'),
]
If you have followed all the steps on your own computer, you can see the result in your own browser:
127.0.0.1:8000/members/.
If the server is down, you have to start it again with the
runserver command:
py manage.py runserver
