end

in user.rb, validates have incorrect syntax.

edit - also, check code directly against yours. has git repository here.

  • it looks have different differences in user_spec compared his.

instead of this:

validates :name, presence: true, length: { maximum: 50 } valid_email_regex = /\a[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i validates :email,  presence: true,                    format: { with: valid_email_regex },                     uniqueness: { case_sensitive: false } validates :password, presence: true, length: { minimum: 6 } validates :password_confirmation, presence: true

do this:

validates :name, :presence => true,                   :length => { :maximum => 50 }  valid_email_regex = /\a[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i  validates :email,  :presence => true,                    :format => { :with => valid_email_regex },                     :uniqueness => { :case_sensitive => false }  validates :password, :presence => true,                       :length => { :minimum => 6 }  validates :password_confirmation, :presence => true

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
