javascript - How to get collection name on express.js server -

मेरे पास 2 संग्रह हैं 

  नियुक्ति चालान

मेरी पोस्ट पद्धति में, डेटा को सहेजने से पहले, मैं जांचता हूं कि डेटा पहले से मौजूद है, लेकिन मुझे केवल नियुक्ति संग्रह चाहिए मैं सामान्यत: इनवॉइस कोच ​​बचा जाना चाहता हूं। मैं यह कैसे कर सकता हूँ। मैंने पहले से ही अगर कथन के साथ कोशिश की है लेकिन यह काम नहीं कर रहा है। 

  एप पोस्ट ('/ संग्रह /: संग्रहनाम', फ़ंक्शन (अनुरोध, आरईसी, अगले) {console.log (req। शरीर [0]) यदि ('/ संग्रह /: संग्रहनाम' == '/ संग्रह / नियुक्तियाँ') {req.collection.findOne ({hour_responce: req.body [0] .hour_responce}, फ़ंक्शन (ई, परिणाम) { यदि (परिणाम) {console.log (परिणाम); console.log (e) res.send (500, {त्रुटि: "आपके पास इस समय अवधि पर एक कार्य पहले से है"})} अन्य {req.collection.insert (req (ई, परिणाम) {if (e) रिटर्न (ई) res.send (परिणाम)})}})} अन्य {req.collection.insert (req.body, {}, फ़ंक्शन (ई, नतीजे) {अगर (ई) रिटर्न अगले (ई) res.send (परिणाम)})}})

मैं एक टिप्पणी नहीं जोड़ सकता, इसलिए मैं एक उत्तर जोड़कर कुछ सलाह देने का प्रयास करता हूं

पहले: < / P>

नियुक्तियों या नियुक्तियाँ? वर्तनी के साथ सावधान रहें

दूसरा:

बेन फॉर्च्यून सही है उपयोग हो सकता है:

यदि (req.params.collectionName == 'नियुक्ति')

तीसरा:

ऐसा लगता है कि आप mongodb (मैं देख रहा हूँ संग्रह जैसे कुछ खोजशब्द, findOne) देशी मोन्देब नोड ड्रायवरिस के साथ संग्रह की क्वेरी करने का सही तरीका है: db.collection.findOne (क्वेरी, कॉलबैक);

ईमानदारी से, मुझे "req.collection.findOne"

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
