django how to model this table correctly? - django

Question

Following the suggestions from my last post I got this far:
Post model:
class Post(models.Model):
title = models.CharField(max_length=120)
content = models.TextField()
Group model:
class Group(models.Model):
title = models.CharField(max_length=200)
url = models.URLField(unique=True)
contact_updated = models.DateField(auto_now=False, auto_now_add=True)
group_status = models.CharField(max_length=20)
admin = models.CharField(max_length=20)
admin_status = models.CharField(max_length=20)
frequency = models.IntegerField() # allowed post frequency
frq_scale = models.CharField(max_length=20, blank=True)
obs = models.TextField(blank=True)
posts = models.ManyToManyField(Post, through='control.Control')
Control model:
class Control(models.Model):
published = models.DateField(auto_now=False, auto_now_add=False)
post = models.ForeignKey('posts.Post', on_delete=models.CASCADE)
group = models.ForeignKey('groups.Group', on_delete=models.CASCADE)
This is control for posts in groups. I can have 1 post published in many groups controlled from Control model.
CORRECTION:
It is possible for a Post to be published in many groups.
How can I produce the table (link above) with those models? Or perhaps there is something I need to change?
The table I want to produce

Answer 1

class Control(models.Model):
published = models.DateField(auto_now=False, auto_now_add=False)
post = models.ForeignKey('posts.Post', on_delete=models.CASCADE)
group = models.ForeignKey('groups.Group', on_delete=models.CASCADE)
class Meta:
unique_together = (post, group )

Answer 2

I ended up creating a dictionary in the view to be passed to the template.
I haven't changed the models.
This is the view:
def control_list(request):
group_status = STATUS_LIST
group_query_idx = 1
period_initial = date.today()-timedelta(days=30)
period_final = date.today()
if request.method == "POST":
filter_form = FilterControl(request.POST)
if filter_form.is_valid():
group_query_idx = int(filter_form.cleaned_data['group_status'])
period_initial = filter_form.cleaned_data['period_initial']
period_final = filter_form.cleaned_data['period_final']
else:
filter_form = FilterControl()
if group_query_idx:
filtered_groups = Group.objects.filter_by_status(group_status[group_query_idx])
queryset_list = Control.objects.filter_by_group_status(group_status[group_query_idx])\
.filter(published__range=[period_initial, period_final])
query = request.GET.get("q")
if query:
queryset_list = queryset_list.filter(
Q(post__content__icontains=query) |
Q(post__title__icontains=query) |
Q(group__title__icontains=query) |
Q(group__admin__icontains=query) |
Q(group__obs__icontains=query)
).distinct() # avoid duplicated items
controls_per_group = {}
for group in filtered_groups:
control = queryset_list.filter(group_id=group.id)
controls_per_group[group.title] = control
context = {
"object_list": queryset,
"title": "Control",
"controls_per_group": controls_per_group,
"column": range(10),
"group_status": group_status,
"filter_form": filter_form,
}
return render(request, "control_list.html", context)
And this is the template:
<table class="table table-hover table-striped">
<thead class="thead-inverse">
<tr>
<th class="text-center">Action</th>
<th class="text-center">Group</th>
{% for value in column %}
<th class="text-center">#</th>
{% endfor %}
</tr>
</thead>
{% for key, value in controls_per_group.items %}
<tr>
<td class="text-center"><a class='btn btn-info btn-xs disabled' href="#"><i class="fa fa-pencil"></i></a>
<i class="fa fa-trash-o"></i></td>
<th class="text-center">{{ key }}</th>
{% for control in value %}
<th class="text-center">{{ control.published | date:"d/m/y" }}<br>{{ control.post.id }}</th>
{% endfor %}
</tr>
{% endfor %}
