Goal: Get the arrival time from Google Map’s API and convert it into a datetime object
So I started to incorporated my Google Map Duration code into Rideminder, but then I realized that it doesn’t matter how long the duration of the trip is! HA! I care about what google has estimated as their arrival time. If I can get the that then I can send it into my database. So lets play with getting the arrival time from what I have.
I had to change my rawjson request from ‘duration’ to ‘arrival_time’, which worked wonderfully! — this is how I parse out the data that I am looking for from my rawjson that I get from my google map api request, more information about that is from an earlier post — This gives me data like: “3:40pm”, “11:12am” and “8:00pm.” So instead of working with milliseconds I decided to change it into a datetime object (since my postgres has a column type for datetime). I know that I’ll have to parse this data out anyways, I went ahead and did that before my datetime research. I saved the parsed rawjson as arrival_time_raw and then made a arrival_time_raw_split and split it on the ‘:’. I placed an if statement that if the last two items in the arrival_time_raw are ‘pm’ for it set arrival_time_hour to 12 (so it changes the pm into 24hour time). Then I processed the hour and min split items. Cool!
Now I need to figure out this whole datetime thing. I started with the docs: 8.1 Datetime. There are so many different options and choices. Going through it, I’m thinking datetime.datetime will work for me. But I wanted to find other sources. I found an article by Marina Mele called “13 Useful Tips About Python datetime Objects“. I totally loved it since it had short, simple examples. I think I appreciate having something simple at first, so my mind can digest the concept in pieces versus learning about the concept and ALL THE THINGS it can do. I played around in -i python (this is interactive python, for more info). I created datetime objects and played with the idea of finding the differences between two datetime objects. Then I found out that I can create datetime objects with the current information and edit them.
To use the arrival time to make a datetime object with its information, you can create a “now” with ‘datetime.datetime.now().’ Then with the parsed out json of the arrival time, I can place the future time (arrival time) into the now datetime object using .replace() – creating my arrival time’s datetime object. Yeah!
I removed two of the original functions and replaced it with one that processes rawjson, to parse out the arrival time and creates the datetime object with the arrival time information.
