User is not created in rails console-CodePudding

my issue is when I am creating a user in the rails console then it is not created. You can also check the below code:

This is my console:

Loading development environment (Rails 7.0.4)
irb(main):001:0> User.create(name: 'Tom', photo: 'https://unsplash.com/photos/F_
-0BxGuVvo', bio: 'Teacher from Mexico.')
=> 
#<User:0x00007fb4e899aa80
 id: nil,
 name: "Tom",
 photo: "https://unsplash.com/photos/F_-0BxGuVvo",
 bio: "Teacher from Mexico.",
 posts_counter: nil,
 created_at: nil,
 updated_at: nil>

These are my schema:

 create_table "comments", force: :cascade do |t|
    t.string "text"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.bigint "post_id"
    t.bigint "author_id"
    t.index ["author_id"], name: "index_comments_on_author_id"
    t.index ["post_id"], name: "index_comments_on_post_id"
  end

  create_table "likes", force: :cascade do |t|
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.bigint "post_id"
    t.bigint "author_id"
    t.index ["author_id"], name: "index_likes_on_author_id"
    t.index ["post_id"], name: "index_likes_on_post_id"
  end

  create_table "posts", force: :cascade do |t|
    t.string "title"
    t.string "text"
    t.integer "comments_counter"
    t.integer "likes_counter"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.bigint "author_id"
    t.index ["author_id"], name: "index_posts_on_author_id"
  end

  create_table "users", force: :cascade do |t|
    t.string "name"
    t.string "photo"
    t.string "bio"
    t.integer "posts_counter"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end

  add_foreign_key "comments", "posts"
  add_foreign_key "comments", "users", column: "author_id"
  add_foreign_key "likes", "posts"
  add_foreign_key "likes", "users", column: "author_id"
  add_foreign_key "posts", "users", column: "author_id"

This is my user model:

class User < ApplicationRecord
  has_many :likes, foreign_key: "author_id"
  has_many :comments, foreign_key: "author_id"
  has_many :posts, foreign_key: "author_id"

  validates :name, presence: true
  validates :posts_counter, numericality: { only_integer: true, greater_than_or_equal_to: 0 }

  def most_recent_posts
    posts.order(created_at: :desc).limit(3)
  end
end

Thank you in advance.

You can check the above code and if anyone solves this problem then please help me.

CodePudding user response：

Your user model is validating posts_counter, but you aren't providing one.

So User.create is failing on this validation. You should be able to replicate this output:

Loading development environment (Rails 7.0.4)
irb(main):001:0> user = User.create(name: 'Tom', photo: 'https://unsplash.com/photos/F_
-0BxGuVvo', bio: 'Teacher from Mexico.')
=> 
#<User:0x00007fb4e899aa80
 id: nil,
 name: "Tom",
 photo: "https://unsplash.com/photos/F_-0BxGuVvo",
 bio: "Teacher from Mexico.",
 posts_counter: nil,
 created_at: nil,
 updated_at: nil>
> user.errors.messages
# will say something like "posts_counter must be greater than or equal to 0"

If you want posts_counter to be optional, you must explicitly declare this:

validates :posts_counter, numericality: { only_integer: true, greater_than_or_equal_to: 0 }, allow_nil: true

If you want, you could instead change your migration to set a default value:

create_table :users do |t|
  ...
  t.integer :posts_counter, default: 0, null: false
  ...
end

CodePudding user response：

As you have a validation defined for the posts_counter attribute, you should provide a value:

posts_counter: 0

Or you can "relax" your validation to allow blank values:

validates :posts_counter, 
  numericality: { only_integer: true, greater_than_or_equal_to: 0 },
  allow_blank: true

Don't forget you can check the object errors by:

user = User.create(...)
user.errors.full_messages
