Stick to these conventions and most of the problem described later will never occur. The model name will also contain both words but without the underscore, PartyPlanner. So if you have a table that contains party planners you If you have tables that you need more than one word to describe should have both words in the Table names consisting of more than one word should have the words seperated by an underscore. Of the primary key so in the posts' table the foreign key linking the post to the user is user_id. You name the column with the singular form of the table and then an underscore followed by the column name Registry example you use both the id from the books table and the libraries' table in your pivot table. If we take our blog example you add aįoreign key to the posts' table to tell the database which user has created the post or as in the book Foreign keys should be named in the singular form of the table reference and the word id seperated by an underscore.Ī foreign key is used to define the relation between two tables.
The name for this unique identifier should be id.
Necessary when that identifier is used in a relationship with another table. You can use another kind of unique value, but it can cause your database to grow more than Primary keys are named idĪ primary key is the unique identifier in a table. In our case with books and libraries it would become book_library. The naming convention is that you take the table names in their singular formĪnd snake case them together in alphabetical order. So to solve this many-to-many relation we use a pivot table. Now a library has many books and a book can be in many libraries. If we look at a book registry application we might have the following tables Pivot tables should be singular form of the tables joined with an underscore in alphabetical order.Ī pivot table is just a regular table joining two other tables together via their primary keys.
Laravel uses a pluralization library for converting model names to plural form behind the scenes. Then we should use the proper grammatical for it. How about when the plural form or the word is bent a little differently than just add in an s to the word. Well it's quite simple we have the following parts in our application. The blog post and any comments that visitors might make to the post. If we look at a simple blog application, we need somewhere to store the username, Table names consisting of more than one word should have the words seperated by an underscore.Foreign keys should be named in the singular form of the table the reference and the word id seperated by an underscore.Pivot tables should be singular form of the tables joined with an underscore in alphabetical order.They are not that many, so they are pretty easy to remember. You get a lot of stuff out of the box so to say if Some might not agree with the naming conventions that Laravel uses but by following The value issue AKA SQLSTATE: General error: 1366 Incorrect value:.The truncated value AKA SQLSTATE: String data, right truncated:.The missing default value AKA SQLSTATE: General error: 1364 Field doesn't have a default value.The irksome null value AKA ERROR 1048 (23000): SQLSTATE: Integrity constraint violation:.
