    The reason is you did not put " Autoincrement" for the id column in the recipe table. You can try this sql query below:

    drop table if exists recipes;
    drop table if exists categories;
    create table categories (
    id int not null auto_increment,
    name varchar(100) not null default '',
    primary key(id)
    ) engine=InnoDB;

    create table recipes (
    id int not null auto_increment,
    category_id int not null,
    title varchar(100) not null default '',
    description varchar(255) null,
    date date null,
    instructions text null,
    constraint fk_recipes_categories foreign key (category_id) references categories(id),
    primary key(id)
    ) engine=InnoDB;



    It will create both Recipe and Catagory tables and will drop if you had them previously.

      Alternatively you can create only the Recipes table:


      create table recipes (
      id int not null auto_increment,
      title varchar(100) not null default '',
      description varchar(255) null,
      date date null,
      instructions text null,
      primary key(id)
      ) engine=InnoDB;

        I had a similar error, and it ended up being a typo in the controller code. @params has an 's'... It through me for a loop for quite awhile.
