I have a form which looks like this:<\/p>\n
class AddressSearchForm(forms.Form):\n \"\"\"\n A form that allows a user to enter an address to be geocoded\n \"\"\"\n address = forms.CharField()\n<\/code><\/pre>\nI’m not storing this value, however, I am geocoding the address and checking to make sure it is valid:<\/p>\n
def clean_address(self):\n address = self.cleaned_data[\"address\"]\n return geocode_address(address, True)\n<\/code><\/pre>\nThe geocode function looks like this:<\/p>\n
def geocode_address(address, return_text = False):\n \"\"\" returns GeoDjango Point object for given address\n if return_text is true, it'll return a dictionary: {text, coord}\n otherwise it returns {coord}\n \"\"\" \n g = geocoders.Google()\n try:\n #TODO: not really replace, geocode should use unicode strings\n address = address.encode('ascii', 'replace') \n text, (lat,lon) = g.geocode(address)\n point = Point(lon,lat)\n except (GQueryError):\n raise forms.ValidationError('Please enter a valid address')\n except (GeocoderResultError, GBadKeyError, GTooManyQueriesError):\n raise forms.ValidationError('There was an error geocoding your address. Please try again')\n except:\n raise forms.ValidationError('An unknown error occured. Please try again')\n\n if return_text:\n address = {'text':text, 'coord':point}\n else:\n address = {'coord':point}\n\n return address\n<\/code><\/pre>\nWhat I now need to do is create a view that will query a model using the address data to filter the results. I’m having trouble figuring out how to do this. I’d like to use CBV’s if possible. I can use FormView to display the form, and ListView to display the query results, but how do I pass the form data between the two?<\/p>\n
Thanks in advance.<\/p>\n
UPDATE: I know how to query my model to filter the results. I just don’t know how to properly combine using a Form and Class Based Views so that I can access the cleaned_data for my filter. e.g:<\/p>\n
Process should be:<\/p>\n
1) Display form on get 2) Submit form and validate (geocode address) on post 3) Run query and display results<\/p>\n
address = form.cleaned_data['address']\npoint = address['coord']\nqs = model.objects.filter(point__distance_lte=(point, distance)\n<\/code><\/pre>\n\n- \n
Ok, here’s a generic version of what ended up working based on psjinx direction:<\/p>\n
