arrays - Accepting form fields with square brackets in the name in Rails -

-

in rails app, i've run case i'd have checkbox name ends in square brackets, e.g.:

name="foo[bar][baz[]]"

other special characters seem handled correctly, looks rails stripping out square brackets , treating them declaring array rather being part of name. needs done allow arbitrary characters (brackets in particular) in name , have them processed correctly rails?

that's because square brackets not allowed in specification:

id , name tokens must begin letter ([a-za-z]) , may followed number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), , periods (".").

from html 4 basic html data types

about rails part, , combining these 2 answers (1 , 2):

rails make use of square brackets make associations in params hash, shouldn't mess names.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
