ruby on rails - Error on migration: SQLite3::SQLException: no such table: main.users -

-

i'm still pretty new rails world. i've been working on skill @ time thought i'd give omni-auth twitter crack. i've been reading through tutorial on sitepoint:

rails authentication oauth 2.0 , omniauth

i'm find until point has me create user model , modify migration file before running rake db:migrate. here's migration file based on instructions:

class createusers < activerecord::migration   def change     create_table :users |t|       t.string :provider, null: false       t.string :uid, null: false       t.string :name       t.string :location       t.string :image_url       t.string :url       add_index :users, :providers       add_index :users, :uid       add_index :users, [:provider, :uid], unique: true        t.timestamps null: false     end   end end

but when run rake db:migrate throws error:

sqlite3::sqlexception: no such table: main.users: create  index "index_users_on_providers" on "users" ("providers")/users/jrshafer/.rvm/gems/ruby-2.2.1/gems/sqlite3-1.3.11/lib/sqlite3/database.rb:91:in `initialize'

any provide aspiring developer appreciated.

you can view full repo here: kronotweeter github repo

you should create table in 1 block , add indexes. in current code, trying add indexes in same create_table block.

try replacing current code piece of code:

class createusers < activerecord::migration   def change     create_table :users |t|       t.string :provider, null: false       t.string :uid, null: false       t.string :name       t.string :location       t.string :image_url       t.string :url       t.timestamps null: false     end # have end create_table block here      # have have add_index statements     add_index :users, :providers     add_index :users, :uid     add_index :users, [:provider, :uid], unique: true   end end

then run:

bundle exec rake db:migrate

this should fix problem.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
