I think with regard to the domain name, and virtual host config, you just point to the public folder as the server root/directory root but I mean when you go up one directory level eg. You can see /app/, /config/, /database/, etc. Those should definitely not be visible by public right?Or at least set indexing off so they see a 403 Forbidden403. Sep 12, 2013  Creating Foreign Keys via Laravel Migration. I am working on an app on Laravel 4 which requires two tables users and userprofiles. ('userid')-unsigned; // this is meant to be used as a foreign key However, after doing php artisan migrate it would throw an error.

Jan 27, 2015  This tutorial shows how you can use foreign keys using relationships in laravel 4.

The Laravel Schema class provides a database agnostic way of manipulating tables. It works well with all of the databases supported by Laravel, and has a unified API across all of these systems.

Creating & Dropping Tables

To create a new database table, the Schema::create method is used:

The first argument passed to the create method is the name of the table, and the second is a Closure which will receive a Blueprint object which may be used to define the new table.

/generate-private-key-filezilla-server.html. To rename an existing database table, the rename method may be used:

To specify which connection the schema operation should take place on, use the Schema::connection method:

To drop a table, you may use the Schema::drop method:

Adding Columns

To update an existing table, we will use the Schema::table method:

The table builder contains a variety of column types that you may use when building your tables:

CommandDescription
$table->bigIncrements('id');Incrementing ID using a 'big integer' equivalent.
$table->bigInteger('votes');BIGINT equivalent to the table
$table->binary('data');BLOB equivalent to the table
$table->boolean('confirmed');BOOLEAN equivalent to the table
$table->char('name', 4);CHAR equivalent with a length
$table->date('created_at');DATE equivalent to the table
$table->dateTime('created_at');DATETIME equivalent to the table
$table->decimal('amount', 5, 2);DECIMAL equivalent with a precision and scale
$table->double('column', 15, 8);DOUBLE equivalent with precision, 15 digits in total and 8 after the decimal point
$table->enum('choices', array('foo', 'bar'));ENUM equivalent to the table
$table->float('amount');FLOAT equivalent to the table
$table->increments('id');Incrementing ID to the table (primary key).
$table->integer('votes');INTEGER equivalent to the table
$table->longText('description');LONGTEXT equivalent to the table
$table->mediumInteger('numbers');MEDIUMINT equivalent to the table
$table->mediumText('description');MEDIUMTEXT equivalent to the table
$table->morphs('taggable');Adds INTEGER taggable_id and STRING taggable_type
$table->nullableTimestamps();Same as timestamps(), except allows NULLs
$table->smallInteger('votes');SMALLINT equivalent to the table
$table->tinyInteger('numbers');TINYINT equivalent to the table
$table->softDeletes();Adds deleted_at column for soft deletes
$table->string('email');VARCHAR equivalent column
$table->string('name', 100);VARCHAR equivalent with a length
$table->text('description');TEXT equivalent to the table
$table->time('sunrise');TIME equivalent to the table
$table->timestamp('added_on');TIMESTAMP equivalent to the table
$table->timestamps();Adds created_at and updated_at columns
$table->rememberToken();Adds remember_token as VARCHAR(100) NULL
->nullable()Designate that the column allows NULL values
->default($value)Declare a default value for a column
->unsigned()Set INTEGER to UNSIGNED

Using After On MySQL

If you are using the MySQL database, you may use the after method to specify the order of columns:

Renaming Columns

To rename a column, you may use the renameColumn method on the Schema builder. Before renaming a column, be sure to add the doctrine/dbal dependency to your composer.json file.

Note: Renaming enum column types is not supported.

Dropping Columns

To drop a column, you may use the dropColumn method on the Schema builder. Before dropping a column, be sure to add the doctrine/dbal dependency to your composer.json file.

Checking Existence

Checking For Existence Of Table

You may easily check for the existence of a table or column using the hasTable and hasColumn methods:

Adding Indexes

The schema builder supports several types of indexes. There are two ways to add them. First, you may fluently define them on a column definition, or you may add them separately:

Or, you may choose to add the indexes on separate lines. Below is a list of all available index types:

CommandDescription
$table->primary('id');Adding a primary key
$table->primary(array('first', 'last'));Adding composite keys
$table->unique('email');Adding a unique index
$table->index('state');Adding a basic index

Foreign Keys

Laravel also provides support for adding foreign key constraints to your tables:

In this example, we are stating that the user_id column references the id column on the users table. Make sure to create the foreign key column first!

You may also specify options for the 'on delete' and 'on update' actions of the constraint:

To drop a foreign key, you may use the dropForeign method. A similar naming convention is used for foreign keys as is used for other indexes:

Note: When creating a foreign key that references an incrementing integer, remember to always make the foreign key column unsigned.

Dropping Indexes

To drop an index you must specify the index's name. Laravel assigns a reasonable name to the indexes by default. Simply concatenate the table name, the names of the column in the index, and the index type. Here are some examples:

CommandDescription
$table->dropPrimary('users_id_primary');Dropping a primary key from the 'users' table
$table->dropUnique('users_email_unique');Dropping a unique index from the 'users' table
$table->dropIndex('geo_state_index');Dropping a basic index from the 'geo' table

Dropping Timestamps & SoftDeletes

To drop the timestamps, nullableTimestamps or softDeletes column types, you may use the following methods:

CommandDescription
$table->dropTimestamps();Dropping the created_at and updated_at columns from the table
$table->dropSoftDeletes();Dropping deleted_at column from the table

Storage Engines

To set the storage engine for a table, set the engine property on the schema builder:

Steps To Take After Generating A New Key Laravel System

I'm having trouble adding foreign keys to my database in laravel using migrations. Since migrations can't be reordered, I can't put them in my table creation migrations directly without needing to hack the times so that things get created in the right order. However, I'm not having any luck creating them after, either, and all my searches have turned up is people (somewhat unhelpfully) suggesting that I put them in the create methods.
