In Django's multi-table inheritance, can the upload_to argument be overridden? -

-

निम्न कोड के लिए: 

  वर्ग छवि (models.Model): alt_name = मॉडल क्लास स्नैपशॉट (छवि): सोर्स = मॉडल। छवि फ़िल्ट (अधिकतम_ लैंब = 1024, अपलोड_ टू = 'बटन')। = Models.ImageField (max_length = 1024, upload_to = 'स्नैपशॉट्स') वर्ग बैनर (छवि): स्रोत = मॉडल। छवि फ़िल्ट (अधिकतम_लाँग = 1024, अपलोड_to = 'बैनर')

इसमें ऊपर के मामलों में, मैं अपने प्रत्येक अपलोड फ़ोल्डर को अपने अपलोड फ़ोल्डर में अपलोड करना चाहता हूं। उदाहरण के लिए, बैनर बैनर नामक एक फ़ोल्डर के नीचे जाएंगे और स्नैपशॉट स्नैपशॉट के अंतर्गत जाएंगे। उपर्युक्त कार्यों के अनुसार अपेक्षित, लेकिन मैं प्रत्येक उप-कक्षा के लिए ImageField दोहरा रहा हूँ। क्या मेरे लक्ष्य को प्राप्त करने का एकमात्र तरीका है या क्या एक ड्रयर पद्धति है?

तर्क एक है कॉल करने योग्य है, इसलिए आप किसी फ़ंक्शन में पास कर सकते हैं। आप इस तरह से कुछ कर सकते हैं: 

  आयात ओएस डीआर def_path (उदाहरण, फ़ाइल नाम): वापसी os.path.join (उदाहरण .__ वर्ग __.__ नाम__ + 'एस', फ़ाइल नाम) वर्ग छवि (मॉडल । मॉडेल): alt_name = models.CharField (max_length = 200) url = models.CharField (max_length = 255, रिक्त = सत्य) स्रोत = मॉडल। छवि फ़िल्ड (max_length = 1024, upload_to = upload_path)

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
