I created a scope and pointed it to the array type.
has_scope: by_industry,: type =>: array
And now I want to make this scope working.
I tried to pass parameter in url like this:
http://localhost:3000/v1/find_friends?by_industry=[1,2]
Does not work.
How to correctly write parameter in url when scope is array type?
To pass arrays through query parameters you use the key + brackets syntax:
?foo[]=1&foo[]=2
It's klunky and its ugly but thats how its been done since the early days of the web and this old CGI convention is used by Rack. The main advantage vs foo=[1,2] is that it is language agnostic and the params can be parsed out without interpreting the string (which is a security hazard).
