How can I access the data in a Django form field form a view? -

-

मेरे पास एक सरल Django फ़ॉर्म है: 

  वर्ग testForm (forms.Form): सूची = Forms.CharField () डीईएफ़ getItems (स्वयं): # मैं यह कैसे करते हैं? सूची में संग्रहीत डेटा तक पहुंचें। वापसी self.list.split (",") # यह काम नहीं करता

सूची फ़ॉर्म फ़ील्ड एक सीएसवी डेटा वैल्यू स्टोर करता है। एक दृश्य में टेस्टफॉर्म के एक बाहरी उदाहरण से, मैं प्रपत्र फ़ील्ड में संग्रहीत .csv मान सूची को देखने में सक्षम होना चाहता हूं।

फॉर्म डेटा प्राप्त करने के लिए आम तौर पर आप डीजेंगो में क्या करते हैं। 

  form = testForm (request.POST) अगर form.is_valid : # फॉर्म में अब फॉर्म में डेटा होगा। स्कैन किए गए_डेटा ... और: # सत्यापन मान्यकरण त्रुटि ...

अगर आप कुछ डेटा स्वरूपण या सत्यापन करना चाहते हैं तो आप इसे डाल सकते हैं फॉर्म में सत्यापन विधि में या तो पूरे फॉर्म के लिए या एक फार्म फ़ील्ड के लिए यह आपके कोड को अधिक शुष्क बनाने का एक शानदार तरीका है।

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
