I'm trying to filter by doctor objects with a specialisation input i get from the last page but I keep get this error
Traceback:
File "/Library/Python/2.7/site-packages/django/core/handlers/base.py" in get_response

Here is the view where I'm trying to filter them
def doclistings(request):
d = getVariables(request)
s = request.session.get('selection')
d['userselection'] = s
doctors = Doctor.objects.filter(specialization = s).order_by('-likes')
paginator = Paginator(doctors, 20) #Show 20 doctors per page
page = page = request.GET.get('page')
try:
doctors = paginator.page(page)
except PageNotAnInteger:
doctors = paginator.page(1)
except EmptyPage:
doctors = paginator.page(paginator.num_pages)
d['doctors'] = doctors
d['paginator'] = paginator
return render_to_response('meddy1/doclistings.html',d)
Here is the Doctor model
class Doctor(models.Model):
name = models.CharField(max_length=100)
specialization = models.ForeignKey(Specialization)
clinic = models.ForeignKey(Clinic)
seekers = models.ManyToManyField(User, through='UserContent')
likes = models.IntegerField(default=0)
Here is the specialization model
class Specialization(models.Model):
name = models.CharField(max_length=30)
Here is the index template where I've the form
<div class="signup">
<div class="form-group">
<form action="" method="post" >
<select class="form-control" id="selection" name="selection">
<option><b>Find a Doctor...</b></option>
{% for value, text in form.selection.field.choices %}
<option value="{{ value }}">{{ text }}</option>
{% endfor %}
{% csrf_token %}
</select>
<span class="input-group-btn">
<button class="btn btn-primary" type="submit" name="submit" id="ss-submit">Find Doctors</button>
</span>
</div>
</div>
I'm printing it in the doclisting.html to check the selection value I get
<h2>{{userselection}}</h2>
I'm just trying to show filter the doctor objects with a specialization and order by highest likes.
I think you should do this in your views.py:
def doclistings(request):
d = getVariables(request)
s_name = request.session.get('selection') # Change variable name
d['userselection'] = s_name # Update this for new variable name s_name
spec = Specialization.objects.get(name=s_name) # Get spec object
# Now this should work:
doctors = Doctor.objects.filter(specialization = spec).order_by('-likes')
paginator = Paginator(doctors, 20) #Show 20 doctors per page
page = page = request.GET.get('page')
try:....
As @Rohan said you could also do:
def doclistings(request):
d = getVariables(request)
s_name = request.session.get('selection') # Change variable name
d['userselection'] = s_name # Update this for new variable name s_name
# Now this should work:
doctors = Doctor.objects.filter(specialization__name = s_name).order_by('-likes')
paginator = Paginator(doctors, 20) #Show 20 doctors per page
page = page = request.GET.get('page')
try:....
In the second way you don't need to get the specialization object, you use specialization__name
to say to Django that gets the doctors wich foreign key to specialization
has the name
equals to s_name
