Flask App Builder url_for views - flask-appbuilder

Question

I am struggling on how to connect URL_for links in my app.
I have a the basic skeleton app set up.
I wish to make a link to a function (that runs code) that is built in a view (MyView).
I essentially want to pass a variable (var1) to the view 'myview/method2/var1' and have that link showing in the ContactModelView.
Thanks
class MyView(BaseView):
route_base = "/myview"
#expose('/method2/<string:var1>')
#has_access
def fun_var(self, var1):
# go to function_file and run function with var1
param1, param2 = func_file.function(var1)
self.update_redirect()
return self.render_template('method3.html',
param1=param1,param2=param2, param3=prospects)
My models.py file has the following:
class Contact(Model):
id = Column(Integer, primary_key=True)
name = Column(String(150), unique = True, nullable=False)
var1 = Column(String(150))
contact_group_id = Column(Integer, ForeignKey('contact_group.id'))
contact_group = relationship("ContactGroup")
def prospect(self):
return Markup(
'prospect')
def __repr__(self):
return self.name
I then have in views:
class ContactModelView(ModelView):
datamodel = SQLAInterface(Contact)
label_columns = {'contact_group':'Contacts Group'}
list_columns = ['name','var1','contact_group', 'action']
show_fieldsets = [
(
'Summary',
{'fields':['name','var1','contact_group', 'prospect']}
)
]

In the documentation regarding BaseView, we see that
Its constructor will register your exposed urls on flask as a Blueprint
So make sure you add the view you created, in order to 'register the blueprint'. Use something like
appbuilder.add_view_no_menu(MyView())
You can run fabmanager list-views on the console to make sure your view was registered.
As your endpoint requires a var1 parameter, you have to provide that to url_for. Something like this will work:
class Contact(Model):
var1 = Column(String(150))
...
def prospect(self):
return Markup(
'prospect')
