Question

I have a web page where users can see data from MongoDB on a map. I want to have several check boxes, radio buttons, etc to filter what is seen on the map. If I was using MySQL I would do

query = "SELECT * FROM table WHERE x = 1" 
if checkbox == "checked":
  query += "AND WHERE y = 2"

How can I replicate that with pymongo?

You simply build up the query dict instead:

query = {'x': 1}
if checkbox == 'checked':
    query['y'] = 2

results = db.collection.find(query)

Doing an OR query would look like this:

query = [{'x': 1}]
if checkbox == 'checked':
    query.append({'y': 2})

results = db.collection.find({'$or': query})
