I have a this models
class Project(models.Model):
name = models.CharField(max_length=20)
description = models.CharField(max_length=200, null=True, blank=True)
creation_date = models.DateTimeField(auto_now_add=True, auto_now=False)
group_owner = models.ForeignKey(User)
def __str__(self, y):
return smart_str(self.name)
class Note(models.Model):
title = models.CharField(max_length=50, null=True, blank=True)
content = models.CharField(max_length=1000)
creation_date = models.DateTimeField(auto_now_add=True, auto_now=False)
updated_date = models.DateTimeField(auto_now_add=False, auto_now=True)
projectId = models.ForeignKey(Project, on_delete=models.CASCADE)
userid = models.ForeignKey(User, on_delete=models.CASCADE)
def __str__(self):
return smart_str(self.title)
which i would like to join them in one view, which would be shown when someone enters to this url http://localhost.com:8000/project/ID . obviously the ID will depend in Project.id and it will have to get all the Notes that are related to it.
Meanwhile my views.py looks like this
class ProjectDetail(generic.DetailView):
model = Project
template_name = 'scribere/project/detail.html'
def get_queryset(self):
return Project.objects.filter(group_owner__exact=self.request.user.id)
class ProjectNoteList(generic.ListView):
context_object_name = 'project_note_list'
template_name = 'scribere/note/index.html'
def get_queryset(self):
return Note.objects.filter(userid__exact=self.request.user.id, projectId__exact=self.kwargs['pk'])
and the template
{% extends "base/adminsNavBar.html" %}
{% load i18n %}
{% block head_title %}{% trans 'Projects Details' %}{% endblock %}
{% block breadcrumbs %}
<div class="breadcrumb"><p>{% trans 'Project Details' %}</p></div>
{% endblock %}
{% block content %}
<div class='row'>
<a href="{% url 'scribere:project_list' %}" class="btn btn btn-primary pull-right" role="button">{% trans 'Back' %}</a>
<a href="{% url 'scribere:project_note_list' project.id %}" class="btn btn btn-primary pull-right" role="button">{% trans 'Notes' %}</a>
</div>
<div>
{{project.name}}
</div>
<div class = "note-list">
<ul>
{% for note in project_note_list %}
<li>
<a href= "#"> {{note}} </a>
</li>
{% endfor %}
</ul>
</div>
{% endblock %}
which doesn't load any information about the note. What am i missing?
Unless you are populating project_note_list
with some information, there will be nothing to iterate over.
By virtue of the ForeignKey
s, and having a Many to one relation the project
object will have a set of notes associated with it, without having to look them up.
You should be able to query them using project.note_set.all()
or in your template by using:
{% for note in project.note_set %}
