i have 2 classes, class a , class b . i've noticed share lot of same code. example: def viewable_by?(user) super || clinic.has_staff_member?(user) || user.system_admin? || self.person == user.person end i want minimize code duplicated between classes. in refactoring, i've found of doesn't fit neatly 1 class falls cleanly in single responsibility principle. want put single module, methods have time formatting, viewing permissions, , few other things. as see it, have few choices. (and bet can suggest others.) object oriented point of view, approach should go , why? use 1 single module shared between both of classes. may not have specific single responsibility, clean code significantly, , keeps in 1 place. make tiny classes , mix in both classes modules. have single responsibility, there many of them, of may have 1 method. seems waste. perhaps use presenter things time formatting, , permissions module shared between both classes. perhaps "cleaner,...

if define structure... struct linknode { int node_val; struct linknode *next_node; }; and create pointer it... struct linknode *mynode = malloc(sizeof(struct linknode)); ...and free() it... free(mynode); ...i can still access 'next_node' member of structure. mynode->next_node my question this: which piece of underlying mechanics keeps track of fact block of memory supposed represent struct linknode? i'm newbie c, , expected after used free() on pointer linknode, no longer able access members of struct. expected sort of 'no longer available' warning. i love know more how underlying process works. the compiled program no longer has knowledge struct linkednode or field named next_node , or that. names gone compiled program. compiled program operates in terms of numerical values, can play roles of memory addresses, offsets, indices , on. in example, when read mynode->next_node in source code of program, compiled machine co...

qsa means if there's query string passed original url, appended rewrite (olle?p=1 rewritten index.php?url=olle&p=1. l means if rule matches, don't process more rewriterules below one. hi, easy examples explain use of l? can't seem grasp explanation above. highly appreciated. thanks. the qsa flag means append existing query string after uri has been rewritten. example: url= http://example.com/foo/bar?q=blah rule: rewriterule ^foo/(.*)$ /index.php?b=$1 result= /index.php?b=bar notice how q=blah gone. because existing query string dropped in favor of 1 in rule's target, (b=$1). if include qsa flag: rewriterule ^foo/(.*)$ /index.php?b=$1 [qsa] the result becomes= /index.php?b=bar&q=blah the l flag means stop applying rules follow. given same url, http://example.com/foo/bar?q=blah , , given rules: rewriterule ^foo - rewritecond %{request_uri} !^/bar.php rewriterule ^(.*)$ /bar.php?z=$1 the first rule gets a...

i need advice on whether on delete cascade suitable use in following table create table category ( id int not null auto_increment primary key, name varchar(255) not null, maincategory int default null, foreign key(maincategory) references category(id) on delete cascade on update cascade ) engine = innodb default charset = utf8; in case, on delete cascade delete sub categories if main category gets deleted.is recommended approach ? you trying create tabular representation of tree structure. using adjacency model, storing id of parent in maincategory field (usually called parent_id). yes, approach totally valid. using on delete cascade securing delete anomalies. i recommend read nested sets - efficient technique representing trees in sql: http://www.evanpetersen.com/item/nested-sets.html how represent data tree in sql? http://en.wikipedia.org/wiki/nested_set_model and book: joe celko "trees , hierarchies in sql smarties"

so in rest have product resource... http://api/product question if i've got domain logic? in object oriented world, might have public class product { int id; public product(){} public int calc(int first, int second) { return first + second; } } how represent business logic? assume can do... public int getcalc(int id, int first, int second) { localproduct = products[id]; return localproduct(first + second); } hence url of service become http://api/product/calc?id=1&first=1&second=2 or (alternatively) http://api/product/1/calc?first=1&second=2 this returns correct result.... i'm wondering if how should represent business business logic? or should doing different way or trying avoid altogether? i'd welcome ideas on how improve this... this depends on system build. take time think how evolve on time, quite hard refactor. general direction heading looks good. this api call ...

while testing search engine, realised not pretty awfull, didn't work lot of combinations user input. i have search field user can input wants. region, city name, zipcode or country or combinations of in no predetermined order or predetermined separator. this quite difficult find cities correspond user wants because of big number of possible combinations user enter in field. what more difficult lot of cities have article in name or composed name, article or words user or couldn't enter. example, since i'm french, i'll use example of city called: la rochelle. the user search la rochelle, rochelle or la-rochelle city's name. if wants more precise, add zip-code after, or before, or country or both... i can't find how optimize search city random user input. there conventional ways ? the table containing cities follow: create table cities ( id int primary key, article text, - contain article if there's one, or null if not city_name te...
