python - Django Templatetag, List index out of range -


I have found a simple template that gives a random fact. When there is no fact in the database, I am getting an exception value Out of range I skipped the query set except for leaving * and also checking that There is a fact in the template. You can see the code given below:

fact.py 

  import the facts.models from the template template django import template = register template. Library () def random_fact (): try: fact = fact (. ')' [0] except fact. Not Axis: Fact = Any Return {Facts}: Facts} register.inview_tag ('facts / fact.html') (random_fact)   
 fact.html  
  & lt ;! - Random Fact Start - & gt; & Lt; Div class = "panel panel-default sidebar" & gt; & Lt; div class = "panel-title" & gt; & Lt; H3 class = "panel-title" & gt; Do you know? & Lt; / H3 & gt; & Lt; / Div & gt; & Lt; Div class = "panel-body" & gt; {% If fact%} and lt; P class = "text-left" & gt; {{Fact.fact}} & lt; / P & gt; & Lt; P class = "text-right" & gt; & Lt; I class = "fa fa-link" & gt; & Lt; / I & gt; & Lt; I & gt; & Lt; A href = "{{fact.website}}" target = "_ blank" & gt; {{Fact.author}} & lt; / A & gt; & Lt; / I & gt; & Lt; / P & gt; {% Else%} & lt; P class = "text-left" & gt; There are currently no study tips! & Lt; / P & gt; {% Endif%} & lt; / Div & gt; & Lt; / Div & gt; & Lt ;! - Random Factors End - & gt;

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.

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...
