God or an Angel litterly told me the answer to this one when i was walking out of the bathroom. I am christian coder, and God helps me code.
short answer:
do something like this:
<select id="users-select" form="search-form" name="users[]" multiple>
the key is to have "[]" in the name
The story behind it:
so i was writing a search engine for note taking app and i was noticing that in my templates that options that were selected in a multiple choice input only reflected the last option in the url. my url looked like this:
http://localhost:4567/reports?clients=5e399c1d181b8942a418c10d&clients=5e52c3f5181b894bcc285cfa
so only the option with the value 5e52c3f5181b894bcc285cfa.
i dispaired slightly having found a (what i thought was a) project crashing bug. Oh no! i thought, im going to have to do double work learning ember or angular or something, specifying the model on front end and the back end stack! and my javascript is a bit lacking! this would push back the completion deadline by months!
so i decided to try the sinatra param gem which is here:
no luck. the types of the param values probably were coerced but params would still only return the last value on the url for that param name.
so i decided to solve it the only way someone who depends on open source should respond to a problem like this. with prayer and project contribution. so i opened an issue here..
and cloned sinatra ready for a pull request after my hack. If God was willing. when im solo, i leave tests until last. but this is a team effort so testing comes first. so i searched in the test folder using rubymines "search in path" command for mentions of params and i came across a behaviour spec at line 575 of this file
so i noted it in the sinatra issue, shelved it for the night and gamed to 4am because i woke up at 2pm becuase of a persistant migrain and im off sick and working on a project.
the next day after my post wakeup routine i came out of the bathroom and i heard an angel speak to me.
he said something like use brackets in the name attributes of my form inputs. Of Coarse! So i went and tried it out to my success and reported it on the sinatra issue and found out that i had a reply. Github user dentarg found a stack exchange question which i hadnt:
They both did not mention how you got the names in the url like that but my angel friend did.
Thanks God and his messenger!
