ruby - How to validate :created_at in model (RAILS 3) - 


  irb (मुख्य): 044: 0 & gt; i1.created_at = & gt; गुरु, 24 अप्रैल 2014 02:41:15 यूटीसी +00: 00 आईआरबी (मुख्य): 045: 0 & gt; i2.created_at = & gt; गुरु, 24 अप्रैल 2014 02:41:15 यूटीसी +00: 00 आईआरबी (मुख्य): 046: 0 & gt; i1.created_at == i2.created_at = & gt; झूठी आईआरबी (मुख्य): 047: 0 & gt; I1.created_at.to_time.to_i == i2.created_at.to_time.to_i = & gt; सच   
 काम करने के लिए नहीं लगता है  validates_uniqueness_of: created_at  
 क्योंकि  
  irb (मुख्य): 046: 0> i1.created_at == i2.created_at = & gt; गलत   
 कैसे बनाया_नेट को मान्य है? एक ही तारीख से बचाने के लिए नहीं चाहते हैं।  
 +++ UPDATE +++  
  irb (मुख्य): 048: 0 & gt; I1.created_at.class = & gt; ActiveSupport :: टाइम विथ ज़ोन आइरब (मुख्य): 04 9: 0 & gt; I2.created_at.class = & gt; ActiveSupport :: TimeWithZone    
 
 
 चूंकि उनके पास अलग सटीक मिलीसेकंड हो सकते हैं।  < P> इस पोस्ट को देखें:  
 संभावनाएं मिलीसेकेंड मान असमान होंगी।  
  डालता है i1.created_at.usec puts i2.created_at.usec  < / पूर्व>

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
