how can i make this easier for myself

Question

Pavlo Liapota · Answer

You have created list `props` updated it but never used it Seems like a bug slightly smiling face I guess you can create local function that will get param by name from context and will nullify it if it is empty Something like this I didn t test ```fun getParam name String String val value = ctx formParam name return if value == null else value ``` Or you can put this function into context class or make it extension function whatever makes sense in your case

oh yeah i could ve just made the list and ran it with that Thanks for that function as well That will make things easier Just a question is my indentation for the book properties acceptable or discouraged

Hamza · Answer

``` <http app post|app post> new book manual manual ctx gt val title = ctx getParam title return manual val author = ctx getParam author return manual val edition = ctx getParam edition val publisher = ctx getParam publisher val subjects = ctx getParam subjects val binding = ctx getParam binding val publishDate = ctx getParam publish date val overview = ctx getParam overview BookRepo add Book title author edition publisher subjects binding publishDate overview ctx html Book has been added ``` I simplified it even more with an infix function

Nice slightly smiling face Your infix function gave me an idea What if you tried operator overloading with extension functions to access params like an array <https kotlinlang org docs reference operator overloading html indexed> I m thinking about a variation like this ```operator fun CtxType get name String String val value = this formParam name return if value == null else value ``` so you can get the params like this ```val title = ctx title return manual val author = ctx author return manual val edition = ctx edition val publisher = ctx publisher etc``` Haven t tried it myself just wanted to share my idea with you in case you like it slightly smiling face

I like operator overloading more than infix function too Now I think you can put `if value == null else value` to separate extension function too slightly smiling face

` return` is missing on sending back an error html

orangy · Answer

What I d do with < C0A974TJ9|ktor> probably javalin has similar mechanism is define an `IncompleteDataException` type ` throw IncompleteDataException lt paramName gt ` and install a generic exception handler to return a standard html page You can reuse it in other routes of course

orangy · Answer

You also might want to return a `Bad Request` status code along with HTML not `200 OK` as you do now

Good idea
