<पूर्व> से django.core.management आयात setup_enver register2 आयात सेटिंग्स से setup_environ (सेटिंग्स) django से django आयात रूपों से contrib.auth.forms रूप _ वर्ग AuthenticationRememberMeForm (AuthenticationForm) ugettext_lazy django.utils.translation आयात से AuthenticationForm आयात: "" "Django के उपवर्ग` `AuthenticationForm`` जो एक मुझे चेकबॉक्स याद कहते हैं।" "" remember_me = forms.BooleanField ( लेबल = _ ( 'मुझे याद रखें'), प्रारंभिक = झूठी, आवश्यक = झूठी,) मुद्रित AuthenticationRememberMeForm.remember_me Traceback (सबसे हाल कॉल पिछले): फ़ाइल 'डी: \ zjm_code \ REGISTER2 \ b.py ", रेखा 26, में से & lt ; मॉड्यूल & gt; प्रिंट AuthenticationRememberMeForm [ 'remember_me'] लेखन त्रुटि: 'DeclarativeFieldsMetaclass' वस्तु unsubscriptable है

Django फ़ॉर्म कोड के लिए घोषणात्मक सिंटैक्स को सुविधाजनक बनाने के लिए forms मॉड्यूल मेटाक्लास का उपयोग करता है एक परिणाम के रूप में, आपको अपने उदाहरण के फ़ील्ड होने के लिए remember_me पर विचार करना चाहिए, कोई वर्ग विशेषता नहीं तो क्षेत्र तक पहुँचने के रूप में तो समझ में आता है: 

  प्रपत्र = AuthenticationRememberMeForm () field_obj = form.fields [ 'remember_me']

या, इसी तरह, मूल्य: 

  प्रपत्र = AuthenticationRememberMeForm (डेटा) यदि form.is_valid (): remember_me_value = form.cleaned_data [ 'remember_me']

जाहिर है, <कोड > डीजेंगोफोर्स ऐसा करने के लिए पर्दे के पीछे कुछ काम कर रहा है। अगर आप यह समझना चाहते हैं कि कैसे, जांचें यदि आप अपने फ़ॉर्म काम बनाना चाहते हैं, तो इसका पालन करने का प्रयास करें।

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
