in my clients table, I have a column named email. But when I made the tests for the clients controller and the model, the tests kept on saying that the clients table has no column named email.
SQLite3::SQLException: table clients has no column named email: CREATE UNIQUE INDEX "index_clients_on_email" ON "clients" ("email")
although I do admit that I didn't initially put that column when I created my table, but I added the column via a separate migration. I ran rake db:migrate and even tried rake db:drop:all, rake db:create:all and then rake db:migrate and it still didn't change anything.
the email column was also added as an index for the clients table.
this is my schema:
ActiveRecord::Schema.define(version: 20161230163248) do
create_table "clients", force: :cascade do |t|
t.string "name", null: false
t.text "email", null: false
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
add_index "clients", ["email"], name: "index_clients_on_email", unique: true
create_table "projects", force: :cascade do |t|
t.text "project_description", null: false
t.string "project_timescale"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.integer "client_id"
end
add_index "projects", ["client_id"], name: "index_projects_on_client_id"
end
the initial migration for the clients table:
class CreateClients < ActiveRecord::Migration
def change
create_table :clients do |t|
t.string :name, presence: true, null: false
t.timestamps null: false
end
end
end
migration to add email as an index for the client table:
class AddIndexToClient < ActiveRecord::Migration
def change
add_index:clients, :email, unique: true
end
end
migration to add the email column:
class AddEmailToClient < ActiveRecord::Migration
def change
add_column :clients, :email, :text
end
end
the following is my database.yml:
# SQLite version 3.x
# gem install sqlite3
#
# Ensure the SQLite 3 gem is defined in your Gemfile
# gem 'sqlite3'
#
default: &default
adapter: sqlite3
pool: 5
timeout: 5000
development:
<<: *default
database: db/development.sqlite3
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
<<: *default
database: db/test.sqlite3
production:
<<: *default
database: db/production.sqlite3
尝试:
RAILS_ENV=test bundle exec rake db:schema:load
