Django ModelForm submit button not working - django

Question

I am trying to make a Django ModelForm that retrieves data from my database using the GET method. When I click the submit button nothing happens. What am I doing wrong?
HTML doc
<form role="form" action="" method="GET" id="form-map" class="form-map form-search">
<h2>Search Properties</h2>
{% csrf_token %}
{{ form.as_p }}
<input type="submit" action= "" class="btn btn-default" value="Submit">
<input type="reset" class="btn btn-default" value="Reset">
</form><!-- /#form-map -->
forms.py
from django import forms
from .models import StLouisCitySale208
from django.forms import ModelForm, ModelMultipleChoiceField
class StLouisCitySale208Form(ModelForm):
required_css_class = 'form-group'
landuse = forms.ModelMultipleChoiceField(label='Land use', widget=forms.SelectMultiple, queryset=StLouisCitySale208.objects.values_list('landuse', flat=True).distinct())
neighborho =forms.ModelMultipleChoiceField(label='Neighborhood',widget=forms.SelectMultiple, queryset=StLouisCitySale208.objects.values_list('neighborho', flat=True).distinct())
policedist = forms.ModelMultipleChoiceField(label='Police district',widget=forms.SelectMultiple,queryset=StLouisCitySale208.objects.values_list('policedist', flat=True).distinct())

Answer 1

You need a get method in your class to tell the button what to do.
class MyView(View):
def get(self, request):
# <view logic>
return HttpResponse('result')

Answer 2

Your form currently has method="GET" which is something you'd use for search, or some other operation which doesn't change the state of the application.
If that's what you want to do, and you're using existing data, through a form, to allow users to query the database, then you'll need to implement a get method on the view in order to implement the logic for this. The following should help with the get() method for FormView;

It sounds like you're hoping to create objects using your model form, so change that to method="POST" and you'll at least allow the application to create your object. There may be more to debug at that point, but you need to start by sending data to the server.
