c# - Creating an object array with a different type from an existing object array in Javascript -

using lambdas , linq in c#, can create new collection type based on collection different type. instance:

var array = new list<foo> { new foo { name = "john", age = "21", title = "mr." } }; // can utilize select function create collection different type var modifiedarray = array.select(foo => new bar { title = foo.title });

i wondering if there improve way in javascript. have:

var array = [{name: 'john', age: '21', title: 'mr.'}]; var modifiedarray = []; array.foreach(function(foo){ modifiedarray.push({title: foo.title}); });

yes. can utilize array.prototype.map

var modifiedarray = array.map(function(x){ homecoming {title: x.title} });

i have problem refreshing $translate property. initially, set "eng". function takes "de" , set it. when retrieve parameter 'hey' still value english. not why.

$rootscope.changelanguage = function(languagekey) { $translate.uses(); //eng $tanslate('hey'); // property eng $translate.uses(languagekey); $translate.uses(); //de $translate('hey'); // property eng !!! };

$rootscope.changelanguage = function(languagekey) { $translate.uses(); //eng $tanslate('hey'); // property eng $translate.uses(languagekey).then(function(data){ $scope.text = $tanslate('hey'); }); //de };

sql - Join 3 tables in Symfony2 -

i have problem query in symfony2, have 3 entites (they simplified bit):

class grouping { /** * @var integer * * @orm\column(name="id", type="integer") * @orm\id * @orm\generatedvalue(strategy="auto") */ protected $id; /** * @var string * * @orm\column(name="name", type="string", length=255) */ protected $name; /** @orm\onetomany(targetentity="groupmember", mappedby="family") */ protected $groupmembers; class groupmember { /** * @var integer * * @orm\column(name="id", type="integer") * @orm\id * @orm\generatedvalue(strategy="auto") */ protected $id; /** * @orm\column(name="group_member_type", type="integer") */ protected $groupmembertype; /** * @orm\manytoone(targetentity="group", inversedby="groupmembers") * @orm\joincolumn(name="group_id", referencedcolumnname="id", nullable=false) */ protected $group; /** * @orm\manytoone(targetentity="test\userbundle\entity\user", inversedby="memberships") * @orm\joincolumn(name="user_id", referencedcolumnname="id", nullable=false) */ protected $user;

user -> standard fosuserbundle user

i want create query returns groups current user grouping member. tell me how that?

here try:

select g (group g inner bring together groupmember gm on g.id=gm.group_id) inner bring together fos_user u on gm.user_id = u.id u.id = 6

but returns

unknown column 'g' in 'field list'

using query builder, assuming you've fetched user , stored in $userobject , bundle name bundlename:

$groups = $this->getdoctrine()->getmanager()->createquerybuilder() ->select('g') ->from('bundlename:group', 'g') ->innerjoin('g.groupmembers', 'gm') ->innerjoin('gm.user', 'u') ->where('u = :user') ->setparameter('user', $userobject) ->getquery() ->getresult();

you need create sure relational mappings correct.

/** @orm\onetomany(targetentity="groupmember", mappedby="family") */ protected $groupmembers;

should be

/** @orm\onetomany(targetentity="groupmember", mappedby="group") */ protected $groupmembers;

Javascript - how do i do a array group and count it, like in MySQL group by given column id? -

Javascript - how do i do a array group and count it, like in MySQL group by given column id? -

i have big array bellow, need grouping first column , count total of channel existence.

for example:

var original_db = [ ["channel1", "online"], ["channel2", "offline"], ["channel3", "online"], ["channel1", "online"], ["lot more"].... ]

expected result original result need be:

var custom_db = [ ["channel1", 2], ["channel2", 0], ["channel3", 1] ]

edit:

for(var key in original_db) { var i; (i = 0; < original_db.length; += 1) { if (original_db[i][0] === original_db[key][0]) { original_db.splice(i, 1); return; } } } console.log(original_db);

use object properties first elements maintain count:

var counts = {}; (var = 0; < original.length; i++) { var key = original[i][0]; if (counts[key]) { counts[key]++; } else { counts[key] = 1; } }

you can turn final array, although i'm not sure why prefer on counts object:

final = []; (var key in counts){ final.push([key, counts[key]]); }

c - Does this code ungetch() '\n'? -

c - Does this code ungetch() '\n'? -

i searched everywhere, cannot find reply this! i'm working on exercise k&r c books function phone call getop. when input illustration 123, code checks each element of input, , stops when not digit. in illustration '\n'; ungetch( '\n' )?

int getop(char s[]) { int i, c; while ((s[0] = c = getch()) == ' ' || c == '\t') ; s[1] = '\0'; if (!isdigit(c) && c != '.') homecoming c; /* not number */ = 0; if (isdigit(c)) /*collect integer part*/ while (isdigit(s[++i] = c = getch())) ; if (c == '.') /*collect fraction part*/ while (isdigit(s[++i] = c = getch())) ; s[i] = '\0'; if (c != eof) ungetch(c); homecoming number; }

ungetch function:

void ungetch(int c) { if(bufp < maxbuf) { printf("ungetch has been called\n"); buf[bufp++] = c; } else printf("the buffer full\n"); }

i thought eof window ctrl+z , , '\n' else...?

iso/iec 9899, programming languages — c:

eof ... expands integer constant expression, type int , negative value, returned several functions indicate end-of-file, is, no more input stream

ctrl-z on windows input key combination causes no more characters returned, not character equivalent of ctrl-z (0x1a).

\n (new line) moves active position initial position of next line.

as original question: since negative value eof different (unsigned char) value, yes, code ungetch() '\n'.
