How to disable BadValueError (required field) value in Google App Engine during scanning all records? -


I want to scan all records so that it can detect that there are no errors inside the data.

How can I disable BadValueError to scan a break due to a lack of required fields?

Consider that I can change to StringProperty not necessary and such properties can be tenths in the actual code - hence such solutions are not useful? 

  class A (db.model): x = db.StringProperty (required = true) for example in A.all (): # if some example (example): example .delete ()   
 Can I use some functions to read directly  datastore.Entity  to avoid such problems that do not require verification?   
 
 
 The solution I found for this problem was to use a flexible query, by this one query Throwing an exception ignores, you can try it:  
  def resilient_query (query): query_iter = iter (query) while true: next_result = query_iter.next () # some object next_resquestion exceptions, etc. E: next_result.delete () query = resilient_query (Excerpt))

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...
