i have rails application , have sql database. using oracle sql developer manage it. question how integrate these 2 can display database data? this big subject, major steps can think of are: for each table in database want include in rail app, define model class inherits activerecord::base if database not respect rails conventions regard naming have provide class methods in each model define primary key column , table name. you create associations in models describe joins between tables.

i'm using mpdf library create , download pdf files, example x1000 (singly using ajax) in loop. error message series of files "allowed memory size of 268435456 bytes exhausted (tried allocate 261900 bytes)" . read have set bigger memory_limit in configuration can't this, because 256m limit. is there other solution error? you can reduce memory usage 2 other ways without increasing memory limit... consider setting $mpdf->simpletables = true; if not need complex table borders, or $mpdf->packtabledata = true; if not mind processing time. packtabledata – use binary packing of table data reduce memory usage both of increase processing time in order save memory usage.

suppose have hlist of type a::b::c::hnil , function (a, b, c) => d val hlist: a::b::c::hnil = ??? def foo(a: a, b: b, c: c): d = ??? now need funciton a::b::c::hnil => d , uses foo return d . def bar(hslist: a::b::c::hnil): d = ??? how implement bar ? you can little more directly using shapeless's fntoproduct , provides toproduct syntax converting functionn function1 taking hlist : import shapeless._, syntax.std.function._ type = string type b = symbol type c = int type d = list[string] val hlist: :: b :: c :: hnil = "foo" :: 'x :: 1 :: hnil def foo(a: a, b: b, c: c): d = list.fill(c)(a + b) def bar(hslist: :: b :: c :: hnil): d = (foo _).toproduct.apply(hslist) in many cases wouldn't want separate bar definition.

i'm getting bit confused new keyword in javascript. take following example function (value) { this.a = value; } function b (value) { return new (value); } console.log ( b (0)); // { a: 0 } console.log (new b (0)); // { a: 0 } i want able create new instance of "a" without having use "new". have "b()", however, when call "new b()" appears same thing "b()", though "new" ignored. in both cases, instanceof equals "a". going on? from the mdn on new : the object returned constructor function becomes result of whole new expression. if constructor function doesn't explicitly return object, object created in step 1 used instead. (normally constructors don't return value, can choose if want override normal object creation process.) this extract shows that what new b isn't "normal" (there's no reason that) the value explicitely returned b return
