python - Django forms: how do I display the initial blank form? -

-

मेरे पास यह दृश्य फ़ंक्शन है: 

  def खोज (अनुरोध): यदि request.method == 'GET': form = SearchForm (request.GET) यदि form.is_valid (): last_name = form.cleaned_data ['last_name'] first_name = form.cleaned_data ['first_name'] वकील = वकील। [अन्य अगर बयानों] .... और: फॉर्म = सर्चफार्म () रिटर्न रेंडर_टो_प्रॉपस ('खोज' html, {'फॉर्म': फॉर्म})

मुझे लगता होगा कि जब पेज लोड करता है else स्टेटमेंट को प्रारंभिक रिक्त रूप से निष्पादित किया जाएगा। पर ये स्थिति नहीं है। प्रारम्भ में प्रपत्र प्रदर्शित करने के लिए मुझे इसे पहले if : 

  डीईफ़ खोज (अनुरोध) के अंदर जोड़ना होगा: यदि request.method == 'GET': फ़ॉर्म = SearchForm (request.GET) यदि form.is_valid (): last_name = form.cleaned_data ['last_name'] first_name = form.cleaned_data ['first_name'] वकील = वकील.ओब्जेस.सॉल्ल () [अन्य अगर बयान] .. प्रपत्र = SearchForm () रिटर्न render_to_response ('search.html', {'form': form}) अन्य: form = SearchForm () रिटर्न render_to_response ('search.html', {'form': form})   
 क्या आप मदद कर सकते हैं क्यों पहला  अगर  कभी झूठा नहीं है? धन्यवाद। 
 
 संपूर्ण दृश्य फ़ंक्शन है

जब आप कोई फॉर्म पोस्ट करते हैं method = GET आप वास्तव में प्रारंभिक अनुरोध से विधि नहीं बदलते हैं: यह method = GET भी था।

आप या तो विधि = POST अपने रूप में, और यदि आपका बयान उस के लिए जांच करेगा, या आप आवश्यक फ़ील्ड के अस्तित्व की जांच कर सकते हैं, first_name , last_name या दोनों, क्योंकि आपके फॉर्म की आवश्यकता है। 

  अगर 'first_name' अनुरोध में। GET या 'last_name' में अनुरोध। GET: form = SearchForm (request.GET) अन्य: form = SearchForm ()

आप इसे इस रूप में अवगत करना चाहेंगे, __ init __ विधि को संशोधित कर सकते हैं, लेकिन आपको इसकी आवश्यकता नहीं है।

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!

unix - Listing all shared memory segments used by a process on AIX5.3+ -

-
I would like to find all the shared memory segments used by a given process I am particularly interested in detecting shmid That's why I can use it in call (shmctl). On Solaris I will just read / proc / $ PID / map to find that information (field pr_shmid) The content of that file is defined by struct prmap_t in the sys / procfs format. Ax also has a / proc / $ PID / map file. Any project is a primate, but unfortunately it has been projected in pr_shmid field. Any ideas how can I get it on AIX5.3 +? I do not particularly know about AX, but I think that ipcs command is quite standard where SysV IPC is supported, so I want to get the ipcs -m command to give the appropriate code; If you can not find a better method, then there may be an option to parse its output.

tsql - Correct sql/hql query (aggregate in where clause) -

-
I want to query the query as below but the question is wrong but describes my intentions. select name, date time, data from record, date time = maximum (date time) Update: OK The description of the query intentions is not very good. My bad I want to select the latest record for each person. i like Mickey's answer and quosnoye (and upyoyed miki), but if your needs are similar to me , You should keep in mind some limitations. First and foremost, this works only when you are looking for the latest record or latest record for the same name. If you want the latest record for each person in a set (a record for each person but the latest record for each), then the above solutions are small. Second, and less importantly, if you work with a large dataset, then it can be slow for a long time. So, what's around the work? Whatever I do is to add a small field to mark the "latest" in the table. Then, when I store a record (which is done in the stored procedu...
