ruby - Rails: validate number of associations -


How can you write verification for many organizations that are outdated? I have written something like this: 

  Validate the documents of the class: publication_count Personal def publication_count if publication count & gt; Template.component_count errors.add (: article, 'too many') Elsif publications count & lt; Template.component_count errors.add (: article, 'not enough') end end   
 are both  publication  and  template  associations. I get a rollback error with this code, even if the record should be valid.   
 
 
 Your code appears correctly, so it seems that the associations are not set up properly or saved. going.  
 Have you tested this:  
     
  •  Both the  publication  and the  template  before you save it > Document  assigned for example?  
  •  There is no rollback error for a different reason, such as the specificity failure?  
  •  Is this the true belief that has been unsuccessful at any other?

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...
