Do you want a database which contains most of cities in the world as well as the countries? This app will save 2 collections to your mongodb:

1. cities(23328 in total)
2. countries(252 in total)

Even better, the

• Language agnostic because it's not a lib. Consume the result database using any language you like.
• Source data from GeoNames.org is under active updates. And this app will let you update in few seconds.
• No other 3rd party libs dependencies but official pymongo
• python main.py to generate the database from source data
• python update.py to update the source data from GeoNames
• Remove any fields you don't need in settings.py
• Support currency symbol which not included in the GeoNames (like $ for USD)
• Easy to add support for other database. See FAQ part.
• Could filter countries which only speak certain languages. (see setting.py)
• Could add "duplicate" data to prevent more queries in MongoDB (see settings.py)

• Python 3
• Python 2 should be fine, but haven't tried.

1. git clone https://github.com/Mr-Binary/world-cities-mongodb.git

2. pip install pymongo

3. Open settings.py, set up your database settings.

4. python main.py

5. Enjoy :)

• To update the source data in data folder: python update.py

• [data]: [Folder] Raw data from GeoNames
• [models]: [Folder] database model for city and country
• [utils]: [Folder] Helper function
• settings.py: Settings
• main.py: Main file to generate the database
• update.py: Update the source data from GeoNames

• The data is from GeoNames.

• The cities contains cities which population greater than 15000.

• How to update the data

  • python update.py

• The URL of source data from GeoNames:

  • cities15000.zip
  • countryInfo.txt

• Every execution will drop the previous collection and generate new one.

• It's very easy, you just need to refactor the save_cities() and save_countries() in mongodb.py, then it will be called at run time with the list of data to insert.
