i trying render peewee query result json using following code: @app.route('/') def index(): c = category.select().order_by(category.name).get() return jsonify(model_to_dict(c)) doing 1 row query. i'm pretty sure issue use of get() , docs returns 1 row. use in place of get() fetch entire results back? this question below pointed me in right direction, is using get() peewee model json what use in place of get() fetch entire results back? modify code be: query = category.select().order_by(category.name) return jsonify({'rows':[model_to_dict(c) c in query]}) alternatively, do: query = category.select().order_by(category.name).dicts() return jsonify({'rows':list(query)})

i used infobox create label marker custom icon. scenario of overlapping markers, labels became illegible , had solution or alternative. it suggested in previous question should make use of markerwithlabel. helps, if markers overlap exactly, can see label still coming through after setting opacity 1 , making background same custom marker. .labels { background-color: #ff5959; } gmarker = new markerwithlabel({ position: somecenterposition, icon: customimageurl, draggable: false, raiseondrag: false, map: map, title: sometitle, labelcontent: atitle, labelanchor: new google.maps.point(someoffsetx, someoffsety), labelclass: "labels", // css class label labelstyle: {opacity: 1} }); the 2 marker behind's label , 15 should displayed on front marker. need have 2 , background behind marker label of 15.

edit - sorry guys, don't think gave enough detail: in parse's ios framework, class called pfobject (classa). framework allows subclass (classb) pfobject . and, if scenario such 1 gave should occur, no issue. my question how possible? understand subclass contain variables/methods not present in main class, making process of casting class subclass unreasonable/unsafe. they have protocol defined pfsubclassing, don't see how allows behaviour occur. i've got following in playground: class classa: nsobject { } class classb: classa { } let objecta = classa() let objectb = objecta as! classb // <- crashes questions: why crash occurring? is there way around this? you know how inheritance works right? class b inherits class a. when make instance of classa , try cast class b, many different things might happen because undefined behavior. problem here what's called slicing. compiler refuses cast down parent class child class because knows ...
