Entity Framework DBContext navigation property loaded by different query? -

-

i have 2 entities, user , messages. load messages , not user message belongs.

this works not include related entity in linq query. doesn't work if load user separately query string user (the name).

i using ef 6.1.0, poco without proxy generation , wcf services pass data. unwanted navigation property value transferred accidentally.

var message = context.messages.firstordefault(m => m.id == 123);  var user = contect.users.firstordefault(u => u.id = 456);  var message_username_composition = new m_u_c{ m = message, username = user.name };  return message_username_composition;

in situation have navigation property (user) of message loaded not so.

disabling lazyloading doesn't help, using separate context solves problem.

is there way other using 2 contexts?

is design?

i not manually set navigation properties null fix this, because may forgotten, because 1 did not realize behavior.

you'll have disable lazy-load , use asnotracking() follows:

ctx.configuration.lazyloadingenabled = false; var message = context.messages.asnotracking().firstordefault(m => m.id == 123);

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
