Django Context isnt rendered - django

Question

I want to render a view with some content. I don't get why the context isn't rendered.
The render_recall_details() function causes problems --> ctx is not None, In my opinion there is no reason why it is not rendered in the html file
views.py
class RecallDetail(View):
template_name = "recall_detail.html"
def get(self, request, *args, **kwargs):
if request.GET:
q = request.GET
q = q.dict()
recall = find_recall_by_querystring(q)
if recall:
self.render_recall_details(request, recall)
else:
return render(request, self.template_name)
return render(request, self.template_name)
def render_recall_details(self, request, obj, *args, **kwargs):
ctx = {
'head': 'Hallo',
'rec': RecallForm(),
'docs': find_docs(obj),
}
print(ctx)
return render(request, self.template_name, context=ctx)
forms.py
class RecallForm(forms.ModelForm):
class Meta:
model = Recall
fields = ('Recall_CODE', 'Recall_NAME', 'Recall_DESCRIPTION', 'Recall_START_DATE', 'Recall_PLANNED_COMPLETATION_DATE', 'Recall_STATUS', 'Recall_DATE_COMPLETED')
my html_template:
{% extends 'base.html' %}
{% block content %}
<div class="content-wrapper">
<h1>{{ head }}</h1>
...
</div>
{% endblock content %}

Answer 1

It seems like a typo in your code-base. In Django, every view must return a response. So, in your case, you are not returning anything if the variable recall has some value. So, change your view as,
class RecallDetail(View):
template_name = "recall_detail.html"
def get(self, request, *args, **kwargs):
if request.GET:
q = request.GET
q = q.dict()
recall = find_recall_by_querystring(q)
if recall:
# you need to put the `return` statement here
return self.render_recall_details(request, recall)
else:
return render(request, self.template_name)
return render(request, self.template_name)
def render_recall_details(self, request, obj, *args, **kwargs):
ctx = {
'head': 'Hallo',
'rec': RecallForm(),
'docs': find_docs(obj),
}
print(ctx)
return render(request, self.template_name, context=ctx)
