asp.net mvc - Updating database entry MVC Entity Framework -


i have payment model 'status' boolean value defaults false. once payment has been made, need update specific payment's 'status' true.

here's code i've been trying use change specific database entry, it's not changing it. doing wrong?

payment payment = new payment(); payment = db.payments.find(orderid); db.entry(payment).state = entitystate.modified; payment.status = true; db.savechanges();

thanks!

this ended working:

using (var con = new applicationdbcontext()) {     payment = con.payments.first(x => x.id == orderid);     payment.status = true;      con.payments.attach(payment);     var entry = con.entry(payment);     entry.property(e => e.status).ismodified = true;     con.savechanges(); } 

payment payment = new payment(); payment = db.payments.find(orderid); payment.status = true; db.entry(payment).state = entitystate.modified; db.savechanges();

Linux vanilla kernel on QEMU and networking with eth0 -

i have downloaded , compiled vanilla linux kernel (3.7.1) used busybox ramdisk booted using qemu. qemu command line qemu-system-i386 -kernel bzimage -initrd ramdisk.img -append "root=/dev/ram rw console=ttys0 rdinit=/bin/ash" -nographic -net nic -net user everything goes well. however, can't use networking on vanilla kernel busybox. 'ifup eth0' tells me / # ifup eth0 ip: siocgifflags: no such device i googled internet can' clue... advice nice thank in advance. most there no driver (in example should e1000) loaded or device has name. in /sys/class/net/ should find listing of available net-devices. if there none (besides lo) driver not loaded. in qemu monitor type "info pci" , show pci-address of ethernet card. should this: ... bus 0, device 3, function 0: ethernet controller: pci device 8086:100e ... this device corresponds /sys/devices/pci0000:00/0000:00:03.0/. files "vendor" , "device" must c...

rdbms - what exactly the undo information lives in oracle? -

some docs says, there "undo tablespaces" implies should create tablespace undo imformation. some docs says, there "undo segment" implies undo information lives in normal tablespaces , use of it's segment. so, undo information lives , organized? earlier releases of oracle database used rollback segments store undo. oracle9i introduced automatic undo management, simplifies undo space management eliminating complexities associated rollback segment management. oracle recommends (oracle 9i , on words) use undo tablespace (automatic undo management) manage undo rather rollback segments. when creating undo tablespace, these automatically created: n undo segments (based on sessions parameter value) named _syssmun$ owned public (usable ops configuration) not manually manageable

clojure - 'get' replacement that throws exception on not found? -

i'd access values in maps , records, throwing exception when key isn't present. here's i've tried. there better strategy? this doesn't work because throw evaluated every time: (defn get-or-throw-1 [rec key] (get rec key (throw (exception. "no value.")))) maybe there's simple method using macro? well, isn't it; has same problem first definition, if evaluation of throw happens later: (defmacro get-or-throw-2 [rec key] `(get ~rec ~key (throw (exception. "no value.")))) this 1 works letting get return value (in theory) never generated other way: (defn get-or-throw-3 [rec key] (let [not-found-thing :i_would_never_name_some_thing_this_021138465079313 value (get rec key not-found-thing)] (if (= value not-found-thing) (throw (exception. "no value.")) value))) i don't having guess keywords or symbols never occur through other processes. (i use gensym generate special value of...
