It will either insert ones that don’t exist or update existing ones. User management table Note that all tables in the system has the ability to filter as well as export or print.

Each one with a link to the original invoice Mail Confirmation Note that if the currency had a yes for notify then I will receive a mail jacques artgraven CURRENCY BUYER USER MANUAL Which looks like this Closing Notes Unfortunantly due to limited time I was unable to get to some of the components. The calculations on surcharge isnt right yet I would have loved to do a lot more testing As to the api part. I didn’t write a full fledged api but simply used serialization to output json and used ajax calls to run to process that in the front. Ideally I would have added an authentication key based on the user id and salt and written a method to verify this then added a page outlining the calls and their paramaters. I would however have used a library to help read my comments or fosRestBundle to help me do this and deal with cross site scripting issues I added simple rules for methods such as post delete and get but these can be much more refined. Given the simplicity of the application I didn’t do a database diagram and instead used an orm that makes the logic pretty readable but a visual view would be useful if I had to share this with a team More commenting. I had added some good commenting but I would have liked to do more I would have used googles location api and added the address as part of the registration and used that to determine the currency based on the address I would have added more validation, such as forcing numbers only where needed and handling transactions notifications when we the wallet goes into arrears. Next I started writing a console application to run the currency update in doing this I would have converted the current call out of the controller and into a service object that I could call from there. jacques artgraven CURRENCY BUYER USER MANUAL It has been added and you can see it if you run: bin/console currency:update Right now it will log out that it worked but it wont actually do anything as I didn’t have time to implement the service object. When deploying it I would have implemented a better deployment strategy and I would have locked down the javascript and css files permissions from writing to avoid js/agent attacks
