Review Unit Tests
Is the code in the right place?
Does the name space make sense? http://blogs.msdn.com/brada/articles/361363.aspx
Is the class / procedure / variable scope correct.
Are the Classes, methods, and variables named correctly? http://blogs.msdn.com/brada/articles/361363.aspx
Are the methods, and variables typed correctly?
Look at the code.
Review for OCP  (open closed principle - Open for extension closed for modification)
Review for DRY Principle (Don't Repeat Yourself - abstract common things and put in single place).
Review for SRP (Single Responsibility Principle - every object has a single responsibility. All the object's services should be focused on that responsibility).

To find locations in your markers table that are within a certain radius distance of a given latitude/longitude, you can use a SELECT statement based on the Haversine formula. The Haversine formula is used generally for computing great-circle distances between two pairs of coordinates on a sphere. An in-depth mathemetical explanation is given by Wikipedia and a good discussion of the formula as it relates to programming is on the Movable Type Scripts website.

Here's the SQL statement that finds the closest 20 locations within a radius of 25 miles to the -33, 151 coordinate. It calculates the distance based on the latitude/longitude of that row and the target latitude/longitude, and then asks for only rows where the distance value is less than 25, orders the whole query by distance, and limits it to 20 results. To search by kilometers instead of miles, replace 3959 with 6371.

SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * si

Create a user for your app, named hello and assigned to a system group called webapps.

$ sudo groupadd --system webapps
$ sudo useradd --system --gid webapps --shell /bin/bash --home /webapps/hello_django hello

I like to keep all my web apps in the /webapps/ directory. If you prefer /var/www/, /srv/ or something else, use that instead.
Create a directory to store your application in /webapps/hello_django/ and change the owner of that directory to your 
application user hello

$ sudo mkdir -p /webapps/hello_django/
