javascript - Is it necessary to create all combination a separately view in CouchDB -

-

मेरे पास CouchDB संग्रहीत में निम्नलिखित दस्तावेज हैं: 

  {"_id": "1 "," _rev ":" 1-e3ff3eb51ccf90e0446ef086fcc6a06c "," sub_name ":" A01 "," प्रकार ":" टेस्ट "," नाम ":" ए "," pos ": 828288} {" _id ":" 2 " "_rev": "1-e3ff3eb51ccf90e0446ef086fcc6a06c", "sub_name": "ए02", "टाइप": "टेस्ट", "नाम": "ए", "पॉज़": 828288} {"_id": "3" "_": "1-ef83655c51f64daa4c074fed9beb8234", "sub_name": "B01", "type": "test", "name": "b", "pos": 171878} {"_id": "4", " _rev ":" 1-ef83655c51f64daa4c074fed9beb8234 "," sub_name ":" B02 "," type ":" test "," name ":" b "," pos ": 171878} {" _id ":" 5 "," _rev ":" 1-52b91ba1577a11bf410999ceb2577206 "," sub_name ":" C01 "," type ":" test "," name ":" c "," pos ": 871963} {" _id ":" 6 "," _rev " : "7", "_rev": "1-52b91ba1577a11bf410999ceb2577206", "sub_name": "c02", "type": "test", "name": "c", "pos": 871963} {"_id" "1-807f46b501b237a6e0f2ba71ffd7f194", "उप-नाम": "डी 101", "प्रकार": "टेस्ट", "नाम ई ":" डी "," पॉज़ ": 1 9 32523} {" _id ":" 8 "," _rev ":" 1-807f46b501b237a6e0f2ba71ffd7f194 "," सब_नाम ":" डी02 "," टाइप ":" टेस्ट "," नाम "डी", "पॉज़": 1 9 32523}

UPDATE मैं पृष्ठ पर चुनिंदा बक्से के माध्यम से विभिन्न दस्तावेज़ों को चुनने के लिए उपयोगकर्ता विकल्प देना चाहता हूं, जहां प्रकार , नाम और उप_नाम को चुना जा सकता है। हालांकि, मुझे एक क्वेरी को गतिशील रूप से ई करने के लिए कोई भी उदाहरण नहीं मिला। G इस तरह से: 

  फ़ंक्शन (डॉक्टर, प्रकार, नाम, उप-नाम) {if (doc.type == प्रकार और amp; doc.name == नाम और amp; amp; doc.sub_name == उप-नाम) {emit (doc._id, doc.pos); }}

क्या मुझे सभी डॉक्टर प्रकार, डॉक्टर और नाम के लिए बनाने के लिए डॉक। नाम और डॉस.sub_name संयोजन अलग से नीचे के समान दिखता है या ऐसा करने का बेहतर तरीका है? < / P> 

  फ़ंक्शन (डॉक्टर) {if (doc.type == "टेस्ट" & amp; amp; doc.name == "ए" & amp; डॉक्टर.sub_name == "A01") { Emit (doc._id, doc.pos); }} फ़ंक्शन (डॉक्टर) {if (doc.type == "टेस्ट" & amp; amp; amp; & amp; डॉक्टर का नाम == "ए" & amp; amp; doc.sub_name == "A02") {emit (doc._id, doc .pos); }} फ़ंक्शन (डॉक) {if (doc.type == "टेस्ट" & amp; amp; doc.name == "B" & amp; amp; doc.sub_name == "B01") {emit (doc._id, doc .pos); }} ...   
 
 
 आप जिस तरह से ' फिर से कोशिश कर रहे हैं - विचार इंडेक्स-टाइम (यानी जब दस्तावेज़ बनाए गए या अद्यतित किए गए) पर बनाए गए हैं और केवल कुंजी या कुंजी श्रेणियों को पास करके पूछे जा सकते हैं किसी भी दस्तावेज़ के आधार पर गतिशील रूप से पूछताछ करना संभव नहीं है।  
 आप क्या कर सकते हैं एक समग्र कुंजी का उत्सर्जन करते हैं:  
  फ़ंक्शन (डॉक्टर) {emit ([doc.type , Doc.name, doc.sub_name], doc.pos); }  
 
 आप कुंजी के रूप में एक सरणी को पास करके दृश्य को क्वेरी कर सकते हैं: 
 
  /.../ my_view? Key = ["test" "बी", "बी 101"]

python - Strange behavior using PyQt4's 'pyqtSlot' decorator before another decorator -

-
I have a strange problem with using the QtCore.pyqtSlot decorator in front of the function decorated with a different decorator. The problem below shows this problem, it immediately provides a low QT program with a single button. When pressing a button, the following happens: (1) The signal 'signal_A' and 'signal_B' sequence are connected to method_A and method_B ​​respectively. (2) signal_A and signal_B signals are emitted. (3) The required behavior is that the method_A and method_B ​​are executed. However, it turns out that both signal_A and signal_B trigger method_A, or method_B ​​(oddly, this is nondeterministic, and different for each part of the program!). It appears to be a bug. This issue is present when PyQt4 binding is used in Qt. It is not present when using PySide (use the '-pyside' parameter to verify) I have seen both problems in Python 2 and 3, and both in Windows and Linux This issue is related to the insertion of a decorator be...

c# - UnhandledExceptionMode.ThrowException for AppDomain.UnhandledException -

I want to set unhandledExceptionMode.ThrowException for current AppDomain and not only for application threads. An exception from the second thread should also be handled by my current Donan_Unimated exception handler. Is it possible? Here's my code: Fixed class program {/// & lt; Summary & gt; Main entry point for the application /// & lt; / Summary & gt; [STAThread] static zero major () {applications Set unhandled exception mode (unwanted exception. Throws up); AppDomain.CurrentDomain.UnhandledException + = New UnrestrictedExceptionEndception (CurrentDomain_UnhandledException); Application.EnableVisualStyles (); Application.SetCompatibleTextRenderingDefault (wrong); Application.Run (New Form 1 ()); } Static Zero CurrentDomain_UnhandledException (Object Sender, UnhandledExceptionEventArgs E) {File.AppendAllText ("Log.txt", (Exception) e.ExceptionObject). Message + environment. Newline); }} Maybe you search for the behavior provided by Applic...

I'm trying to kill a process using a CMD command line from my C # application, but when I start the application does not happen anything. .. When I try to kill with a command prompt, I get the message: "Access denied" I tried to run as my app administrator and the process was killed. How can I not always use "Run as administrator"?
