iphone - Simplest way to encapsulate multiple method arguments? -

+ (planet *)createplanetincontext:(nsmanagedobjectcontext *)context withname:(nsstring *)name type:(nsstring *)type group:(nsstring *)group anddiameter:(nsnumber *)diameter {

if wanted encapsulate arguments "name", "type", "group" , "diameter" single entity passing above method best type utilize encapsulation? above method quick illustration argue fine presented, if there many more arguments needed passed. need bundle info before calling method solution needs quick , simple setup.

+ (planet *)createplanetwithdata:(data *)data incontext:(nsmanagedobjectcontext *)context {

or more inline objective-c practices (more readable) individually list arguments?

i'd want individually list arguments, clarity. sample method you've posted above isn't terribly long, in context of objective-c.

it's readability , documentation. when list arguments it's clear developers coming project what's beingness passed in where, , kinds of objects floating around. automatic documentation generation (eg, doxygen) works off lists of arguments particularly well.

but there point @ which, say, becomes little unwieldy. 20 parameters pass in , method calls going very, long! there other options available - easiest 1 utilize nsdictionary or similar, used in ios ferry bits of info around (particularly notifications, have userinfo dictionary).

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
