PhotosController@store

Currently being refactored to Uploads\UploadPhotoController

1. Verification

• Request Verification

  • The file should be an image

• Check for GPS

  • We extract the EXIF data and check it for GPS keys.
    • If no GPS keys are found, a 500 error is thrown and the process is aborted.
  • We then test for empty "0/0" values, which we believe can be introduced when transferring images across devices.
    • If no GPS values are found, a 500 error is thrown with this information.

• Check For Duplicates

  • We check the dateTime the image was taken at.
  • The user will get an error if they try to upload the same photo twice.

2. Upload the Photo

Actions Used

• UploadPhotoAction x2
  • We use AWS S3 on production, DigitalOcean on staging, and public/local-uploads/ locally.
  • Creates the filepath in year/month/day/fileHashName.jpg format.
  • Uploads the photo.
  • We duplicate the upload with a resized image of 500x500 dimensions for the OpenLitterAI.
    • This should be done asynchronously after everything else has been done.

3. Get GPS & Check For Locations

• Convert EXIF values to lat/lon.

• Reverse Geocode the coordinates at OpenStreetMap to get an address.

  • Use OpenStreetMap address values to populate list of locations at OpenLitterMap.
    • If a new location is created, we fire these events: NewCountryAdded, NewStateAdded, and NewCityAdded.
    • These need to move to after the Photo was created.

4. Create the Photo

• Preprocess
  • Get device model (eg. iPhone 13 Pro / Android Samsung X)
  • Convert the coordinates into a geohash
• Create the record on the photos table.

5. Update Leaderboards & XP.

• We need to move the Users XP to Redis.

• We need daily, weekly, monthly Leaderboards.

6. Dispatch Events & Notifications

• After everything is done, we should dispatch these last.

  • Image Uploaded

    • AddLocationContributor
    • IncreaseLocationTotalPhotos
    • IncreaseTeamTotalPhotos
      • This data needs to move to Redis

  • Locations Created should move here

  • Increment PhotosPerMonth

    • IncrementCountryMonth
    • IncrementStateMonth
    • IncrementCityMonth

  • We also need PhotosPerDay, per week and more.
