What's Covered

This tutorial illustrates how to return a match for a Device Id. It shows how to first get the Device Id from a match, then get a match for that Device Id and return the value of the IsMobile property. This can be useful to look at devices that have already been matched at a previous date.

Code and Explanation

Match with device id example of using 51Degrees device detection. The example shows how to:

  1. Import settings from the 51Degrees settings file

    										
    dataFile = settings.V3_WRAPPER_DATABASE
    properties = settings.PROPERTIES
    cacheSize = settings.CACHE_SIZE
    poolSize = settings.POOL_SIZE
    
    										
  2. Instantiate the 51Degrees device detection provider with these properties

    										
    provider = fiftyone_degrees_mobile_detector_v3_wrapper.Provider(dataFile,
    	properties,
    	cacheSize,
    	poolSize)
    
    										
  3. Produce a match for a single device id

    										
    match = provider.getMatchForDeviceId(deviceId)
    
    										

  4. Extract the value of the IsMobile property

    										
    match.getValues('IsMobile')
    
    										
This example can be run in any directory, but assumes your settings file contains a valid dataFile location and has the IsMobile property selected.

Summary

In this tutorial you have seen how to use the detector to retrieve the IsMobile property for a pre-defined Device ID string. The example can easily be modified to retrieve the value of any other property. Premium and Enterprise data files provide considerably more properties such as IsCrawler , PriceBand , HardwareVendor and ScreenInchesWidth . For a full list of properties and the data files they exist in please see the Property Dictionary .
