Conflict

#1

Hi all,
How to avoid class name conflict in model class and gem class name if both
same??
Example:1) Model class Country
2) gem countries have Country class

When application runs it always take gems countries class Country, where I
have used model country. And gives model query error.

#2

Change the name of your class to something that resembles country, something like area, or state

I have used another gem to resolved the problem, my question is how we can
resolve if there is no alternatives.

Is it not the case that you CAN enforce the use of the correct class by using explicit naming i.e. "namespace::classname"?
That, at least, is my understanding of the documentation. Are there cases where this approach will not work?

They shouldn't clash as long as you call them separately

Have you tried using a module as namespace <https://rubymonk.com/learning/books/1-ruby-primer/chapters/35-modules/lessons/80-modules-as-namespaces> over your model Country class?

Sometimes you can do this, but it can be difficult in a Rails app, since Rails brings expectations about a correspondence between directory/file names and class names.

In the riak-client gem I develop at work, there’s a `Riak::Crdt::Set` class that also uses the standard library `::Set` class, which is, of course, confusing. I have to refer to them with those names (i.e. I can’t just use `Set` ever) in both [code](https://github.com/basho/riak-ruby-client/blob/f1ffbff7dad4dad487103560cc9c06f7abffedd7/lib/riak/crdt/set.rb) and [documentation](http://basho.github.io/riak-ruby-client/crdt.html#toc-sets) to keep both myself and any readers from getting confused.

Thanks for that Bryce - I'm NOT fluent in Rails! That will teach me to read the question!

Don’t date all women named “mary”.

Always personalize your classes and methods to be unique. Always. Security is very very good. Use that even in the placement of where you question if it is needed.

Rule: Never even approach using names that are so obvious.
