PG::DuplicateTable: ERROR: relation “posts” already exists

Question

When I run rake db:migrate I get following output:

== 20141219011612 CreatePost: migrating ======================================= -- create_table("

Answer 1

Check your db/schema.rb

You most likely have the same table being created there in addition to a migration in db/migrate/[timestamp]your_migration

You can delete the db/migrate/[timestamp]your_migration if it is a duplicate of the one found in the schema and it should work.
