In which variable is the model instance stored in customized view? - flask

Question

How can I actually pick up values from my model in a customised template?
Let's assume for this example, the model for Request has an attribute "title".
Following views.py:
class RequestModelView(ModelView):
datamodel = SQLAInterface(Request)
extra_args = {'my_extra_arg':Request}
show_template = 'show_request.html'
list_columns = ['title','description','request_status']
and here the show_requests.html
{% extends "appbuilder/general/model/show.html" %}
{% block show_form %}
This Text is before the show widget
{{ super() }}
This Text is shown below..
<hr>
{{ (self.title) }}; {{pk}}; {{pk['title']}}
{% endblock %}
In which variable can I find my object?
The only parameter that works is {{pk}} (it shows the ID of the Request).
I was thinking of something like item['title']
Thanks.

A very similar question was asked on their Github. I think you would have to use something along these lines:
views.py
class RequestModelView(ModelView):
datamodel = SQLAInterface(Request)
list_columns = ['title','description','request_status']
add_template = 'show_request.html'
#expose('/show_request', methods=['GET', 'POST'])
#has_access
def show_request(self):
get_filter_args(self._filters)
self.extra_args = {'item': list_columns}
return super(RequestModelView, self).add()
show_requests.html:
{% extends "appbuilder/general/model/show.html" %}
{% block show_form %}
This Text is before the show widget
{{ super() }}
This Text is shown below..
<hr>
{{ item['title'] }}
{% endblock %}
Documentation is certainly not very clear in this aspect, but please check template-extra-arguments
I'm not sure if you would still need extra_args = {'my_extra_arg':Request}.

The following example should make things clear:
from .models import cars
beautiful_names = ["John", "Jane", "Bob"]
flowers = ["Aster", "Buttercup", "Roses"]
class IndexView(View):
template_name = "dashboard/dashboard_index.html"
def get(self, request, *args, **kwargs):
all_car_objects=cars.objects.all()
return render(request,
self.template_name,
context={"my_addresslist": beautiful_names,
"my_rose_list": roses},
"all_cars":all_car_objects)
In your template you can then do something like:
<h1>Beautiful Names</h1>
{% for name in my_addresslist %}
<p>{{ name }}</p>
{% endfor %}
<h1>Roses</>
{% if my_rose_list %}
{% for rose in my_rose_list %}
<p>{{ rose }}</p>
{% endfor %}
{% endif %}
<h1>Cars</>
{% if all_cars %}
{% for car in all_cars %}
<div>
<p>{{ car.name }}</p>
<p>{{ car.make }}</p>
<p>{{ car.model }}</p>
</div
{% endfor %}
{% endif %}
So for your example, it comes down to this:
class MyView(ModelView):
datamodel = SQLAInterface(MyTable)
extra_args = {'my_request_list':Request}
show_template = 'show_request.html'
<h1>Requests</>
{% if my_request_list %}
{% for request in my_request_list %}
<p>{{ request }}</p>
{% endfor %}
{% endif %}
