django edit multiple id at once with selecting checkbox - django

Question

I have items where I can easily edit one by one all working nice but in case I want to edit multiple id's at once via selecting with checkbox I am stuck and can't get it work. Where am I doing wrong ?
Here is my codes:
fast_edit.html -> I am passing variables via instance to field.
<div class="row">
<div class="col-sm-12">
<div class="panel panel-default">
<div class="panel-body">
<form class="form-horizontal" action="" method="post" enctype="multipart/form-data">
{%csrf_token%}
{%for field in instance %}
<table class="table">
<tbody>
<tr>
<td width="100">
{{field.label_tag}}
</td>
<td>
{{field}}
</td>
</tr>
</tbody>
</table>
{% endfor %}
<div class="form-group">
<div class="col-sm-offset-6 col-sm6">
<button type="submit" class="btn btn-primary">Update FP Item</button>
</div>
</form>
</div>
</div>
</div>
</div>
forms.py
class FastFPForm(forms.ModelForm):
class Meta:
model = FP
fields = ['FP_Item', 'P_1', 'P_2']
widgets = {
'FP_Item': Textarea(attrs={'cols': 50, 'rows': 3}),
'P_1': Textarea(attrs={'cols': 50, 'rows': 1}),
'P_2': Textarea(attrs={'cols': 50, 'rows': 1}),
}
view.py --> I am sending variables to fast_edit function
def items_home(request):
pfast_type = request.GET.get("pfast_type")
item = request.GET.get("fastedit")
........
elif pfast_type and item:
return fast_edit(pfast_type,item)
Here is my function:
def fast_edit(request,id=None):
if not request.user.is_active:
return render(request, 'login.html')
else:
instance=get_object_or_404(FP,id=item)
form = FastFPForm(request.POST or None,instance=instance)
if form.is_valid():
instance = form.save(commit=False)
instance.user_id = request.user.id
instance.save()
return HttpResponseRedirect(instance.get_absolute_url())
context={
'FP' : FP.FP_Item,
'instance': instance,
'form': form
}
return render(request, 'fast_edit.html', context)
This is my inputs for fastedit and pfast_type to get the id's and the type.
<input type="checkbox" id="P_1" name="pfast_type" value="P_1"/>
<input type="checkbox" id="{{ obj.id }}" name="fastedit" value="{{ obj.id }}"/>
I know that my function is not correct but I couldn't fix it according to my need, so what I want to do is if P_1 checked, I want all selected items editable for P_1 field, if I select P_2 again all selected items editable for me to be able to save on fast_edit page.
Is my logic false ? Is there any other easier method for editing multiple id at once via selecting with checkbox or if I am on the right track can you please give me hint to solve this. Thank you
I added but I don't think I need url right as like as we are editing single id like url(r'^detail/(?P\d+)/$',
urls.py
url(r'^fast_edit/$', views.fast_edit, name='fast_edit'),
