activerecord - Creating and enforcing has_one relationship in rails relational database -


Working on a table of profiles I have an issue to install, is this correct? I am confused about has_many and has_one relations because it is a table with one line for each visited relationship, I have decided to go with has_one

is it correct? Is this also a way to implement the relationship in the ActiveCard?

Model 
  Class ViewProfile & lt; ActiveRecord :: base verifies: seen_profile_id, presence: true is valid: profile_id, presence: true_one: profile_id is_on: seen_profile_id end   
 migration  
 < Code> Create Classviews Profiles & lt; ActiveRecord :: Migration Change Diff change_table: seen_profiles do | T | T.integer: profile_id t.integer: viewed_profile_id end end end   
 edit  
 with it also when I go to my console and type the profile I've seen So does nothing come in the form of any idea? = C Schema should usually be shown!   
 
 
 First of all, you enter   model   and   attributes (especially foreign key)  . In the model,  Attributes  and  Association  will be set to  Models .  
 You have to set your models in this way  
  Class ViewProfile & lt; ActiveRecord :: Base_On: Profile & Class Profile & lt; ActiveRecord :: Base is_to: viewed_profile validates: seen_profile_id, presence: true is valid: seen_profile_id, Specification: right end   
 and your related migration files should look like this  
  Create ClassviewProfile & lt; ActiveRecord :: Migration Change Diff change_table: seen_profiles do | T | T.string: Name End And Class CreateProfile & lt; ActiveRecord :: Migration Change Diff change_table: Profile do | T |         P>

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.

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...
