1fill in blank

easy

💡 Hint

Common Mistakes

Adding extra words like 'user_table'.

Laravel expects table names to be plural and lowercase, like users.

2fill in blank

medium

Laravel

class User extends Model {
    protected $table = '[1]';
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using singular or camel case names in the model.

Adding extra suffixes like '_table'.

The model should specify the plural lowercase table name, users.

3fill in blank

hard

Fix the error in the migration table name to follow Laravel conventions.

Laravel

Schema::create('[1]', function (Blueprint $table) {
    $table->id();
    $table->timestamps();
});

Drag options to blanks, or click blank then click option'

Busers

CuserTable

Duser

💡 Hint

Common Mistakes

Using singular or camel case names.

Using inconsistent naming between model and migration.

Table names must be plural and lowercase, so users is correct.

4fill in blank

hard

Fill both blanks to create a migration for a pivot table between users and roles.

Laravel

Schema::create('[1]', function (Blueprint $table) {
    $table->foreignId('[2]_id')->constrained()->onDelete('cascade');
    $table->foreignId('role_id')->constrained()->onDelete('cascade');
    $table->primary(['[2]_id', 'role_id']);
});

Drag options to blanks, or click blank then click option'

Arole_user

Buser

Cusers

Duser_id

💡 Hint

Common Mistakes

Using singular or camel case for pivot table name.

Using plural form in foreign key names.

The pivot table name is the two related table names in alphabetical order, role_user. The foreign key uses the singular form user.

5fill in blank

hard

Fill all three blanks to define a Laravel model with a custom table name and primary key.

Laravel

class Product extends Model {
    protected $table = '[1]';
    protected $primaryKey = '[2]';
    public $incrementing = [3];
}

Drag options to blanks, or click blank then click option'

Aproducts_custom

Bproduct_id

Cfalse

Dtrue

Attempts:

💡 Hint

Common Mistakes

Using default table name instead of custom.

Not setting primaryKey when using custom keys.

Forgetting to set incrementing to false when needed.

The model uses a custom table name products_custom, a custom primary key product_id, and sets incrementing to false if the key is not auto-incrementing.

Practice

1. In Laravel, what is the recommended naming convention for database tables?

easy

A. Plural, lowercase, and use underscores (snake_case)

B. Singular, uppercase, and use camelCase

C. Plural, uppercase, and use hyphens

D. Singular, lowercase, and use spaces

Solution

1. Step 1: Understand Laravel's default table naming

   Laravel expects table names to be plural and lowercase with underscores separating words (snake_case).

2. Step 2: Compare options with Laravel conventions

   Only Plural, lowercase, and use underscores (snake_case) matches plural, lowercase, and underscores. Others use singular, uppercase, or invalid characters.

3. Final Answer:

   Plural, lowercase, and use underscores (snake_case) -> Option A

4. Quick Check:

   Table names = plural + lowercase + underscores [OK]

Hint: Tables are plural and snake_case in Laravel [OK]

Common Mistakes:

• Using singular table names
• Using camelCase or spaces in table names
• Using uppercase letters in table names

2. Which of the following is the correct Laravel table name for a model named ProductCategory?

easy

A. productCategories

B. productcategories

C. ProductCategories

D. product_categories

Solution

1. Step 1: Convert model name to table name format

   Laravel converts camel case model names to snake_case plural table names.

2. Step 2: Apply plural and snake_case

   ProductCategory becomes product_category, then plural is product_categories.

3. Final Answer:

   product_categories -> Option D

4. Quick Check:

   Model ProductCategory = table product_categories [OK]

Hint: Convert camelCase to snake_case and pluralize [OK]

Common Mistakes:

• Not pluralizing the table name
• Using camelCase or PascalCase for table names
• Using singular form instead of plural

3. Given the Laravel model UserProfile, which table name will Laravel assume by default when querying?

medium

A. userProfile

B. userprofile

C. user_profiles

D. UserProfiles

Solution

1. Step 1: Understand Laravel's default table naming from model

   Laravel converts model names from camel case to snake_case and pluralizes them.

2. Step 2: Apply to UserProfile

   UserProfile becomes user_profile, then pluralized to user_profiles.

3. Final Answer:

   user_profiles -> Option C

4. Quick Check:

   UserProfile model = user_profiles table [OK]

Hint: Model name to snake_case plural table [OK]

Common Mistakes:

• Using singular or camelCase table names
• Not pluralizing the table name
• Using uppercase letters in table names

4. You have a Laravel model named OrderItem but the table is named orderitems. What issue will this cause?

medium

A. Laravel will query the orderitems table correctly without issues.

B. Laravel will not find the table automatically and cause a runtime error.

C. Laravel will throw a syntax error due to table name casing.

D. Laravel will convert the table name automatically to order_items.

Solution

1. Step 1: Check Laravel's table naming expectation

   Laravel expects the table name to be plural and snake_case, so for OrderItem it expects order_items.

2. Step 2: Analyze mismatch impact

   If the table is named orderitems (no underscore), Laravel won't find it automatically and will cause a runtime error.

3. Final Answer:

   Laravel will not find the table automatically and cause a runtime error. -> Option B

4. Quick Check:

   Table name mismatch = runtime error [OK]

Hint: Table name must match snake_case plural exactly [OK]

Common Mistakes:

• Assuming Laravel auto-corrects table names
• Thinking casing causes syntax errors
• Ignoring runtime errors from missing tables

5. You want to use a Laravel model Person but your database table is named people_records. How can you correctly link the model to this table?

hard

A. Set the protected $table property in the model to 'people_records'.

B. Rename the table to people to follow conventions.

C. Change the model name to PeopleRecord to match the table.

D. Laravel will automatically detect the table people_records.

Solution

1. Step 1: Understand Laravel's default table detection

   Laravel expects the table name to be plural snake_case of the model name, so Person expects people.

2. Step 2: Link model to custom table

   To use a differently named table like people_records, set protected $table = 'people_records' in the model.

3. Final Answer:

   Set the protected $table property in the model to 'people_records'. -> Option A

4. Quick Check:

   Custom table name = set $table property [OK]

Hint: Use $table property to link custom table names [OK]

Common Mistakes:

• Assuming Laravel auto-detects non-standard table names
• Renaming model instead of setting $table
• Renaming database tables unnecessarily
