i have a very simple question that somehow it might sound stupid but excuse me . I am working on a project where i use sql server with an existing database where table names are having a schema , forexample dob.Tablename . My question is , if i want to create eloquent model for Tablename , how will i name my class ?
Create new model and add table property:
protected $table = 'existing_table_name';
Just be named the table name removing s corresponding to elequent model name.For example:- Elequent model name User then your database table name is users.

i have problem in laravel. i have created multiple morph in one table.
table structure
table_name : morphicable
id:
model_id: eg: '1'
model_type: eg 'model/comment'
model_one_id: eg: '1'
model_one_type: eg 'model/order'
in above relationship we can saving the data from comment to order and order to comment like many to manay.
Now the problem is that how to get the both data from one ORM method. like some time we save comment in model type and some time in model typeOne.
i want to get the data from both models in one go.
public function morphicable(): MorphMany
{
return $this->morphMany(morphicable::class, 'model');
}
I am curious about how eloquent knows in which table it should save the records we give it by running $ php artisan tinker . I do not actually remember setting so an option.
In Laravel when using Eloquent you should assign a table name using the property $table for example:
protected $table = 'some_thing';
Otherwise it assumes that the table name is the plural form of the model name and in this case for User model the table name should be users. Follwing paragraph is taken from Laravel website:
Table Names
Note that we did not tell Eloquent which table to use for our Flight
model. The "snake case", plural name of the class will be used as the
table name unless another name is explicitly specified. So, in this
case, Eloquent will assume the Flight model stores records in the
flights table.
// You may use this instead:
class Flight extends Model
{
// Explicit table name example
protected $table = 'my_flights';
}
So, if you don't follw this convention when creating/naming your database tables that Laravel expects then you have to tell Laravel the name of the table for a model using a protected $table property in your model.
Read the documentation here.
Actually if you not set the $table property, Eloquent will automatically look the snake case and plural name of the class name. For example if class name is User, it will users.
Here the code taken from Illuminate/Database/Eloquent/Model.php
public function getTable()
{
if (isset($this->table)) {
return $this->table;
}
return str_replace('\\', '', Str::snake(Str::plural(class_basename($this))));
}
Model name is mapped to the plural of table name, like User model maps to users table and so.
When you do
User::all() laravel knows that you want the records from users table.
To specify the table name explicitly you use protected $table ='name' field on model.
Actually, Eloquent in its default way, is an Active Record System just like Ruby On Rails has. Here Eloquent is extended by a model. Those model name can be anything starts with capital letter. Like for example User or Stock
but the funny thing is this active record system will imagine that if no other name of custom table is specified within the class model then the table name should be the small cased plural form of the Model name. In these cases users and stocks.
But by keeping aside theses names you can extensively can provide your own table name within the model. As in Laravel protected $table= 'customTableName'
Or, in a more descriptive way,
class Stock extends Eloquent{
// Custom Table Name
protected $table = 'custom_tables';
}
I hope this will solve your curious mind.
I use factory and seeder in laravel to insert fake data in my tables with my models to test its efficiency, now I have a pivot table post_tag that has post_id and tag_id,
how can I insert fake data in the pivot table.Should I make a model named Post_Tag?
I think this way it's not true...
Thanks
You should create a model called Post_Tag. Every model is associated with a table from your DB. After creating the model you should create the seed file.
Of course you could just create the model and insert a new line in your PostSeeder file but it's nice to have things organized.
I just recently started experimenting with laravel, lovely. One thing l dont understand though is how laravel knows my table l just added a model and the model isnt the exact table name, but just how does it manage to get my table,
Reference to Eloquent Model Conventions:
Note that we did not tell Eloquent which table to use for our Flight
model. By convention, the "snake case", plural name of the class will
be used as the table name unless another name is explicitly specified.
Internally, Laravel does something like this.
$table = $table ?: Str::plural($name);
So it will automatically try to look for the plural of your model name if no $table property is being set.
Laravel follows a Naming convention for Eloquent Classes and Tables.
From Laravel Website | Eloquent: Getting Started
Note that we did not tell Eloquent which table to use for our Flight
model. By convention, the "snake case", plural name of the class will
be used as the table name unless another name is explicitly specified.
So, in this case, Eloquent will assume the Flight model stores records
in the flights table.
Eg.
Class User will by default refers to Mysql Table users (Camel Case to Snake Case and Plural).
Class NotificationsLog will by default refers to Mysql Table notifications_logs (Camel Case to Snake Case and Plural).
But if you don't want to follow the convention then you can Mention the table name explicitly
Eg.
If I want my Class Plane should refers to flights table in Database then following code will work
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Plane extends Model
{
/**
* The table associated with the model.
*
* #var string
*/
protected $table = 'flights';
}
Actually the when you make a model it automatically make a table with it's plural you could change this by added the following code in the model
protected $table= 'table_name';
Please also check the name in the migration it should be same as the name you mentioned in the model class because it might show error while using eloquent class functions due to different table names
If I have database table suggestions_votes, what would be the correct name of Laravel (5.1) Class (SuggestionsVote or SuggestionVote)?
Table was created by migration, using
Schema::create('suggestions_votes', ...
Laravel recommends certain conventions, but they also provide you with options to override them.
If your model is "SuggestionVote", then the table associated with that model will be the snake case plural name of the class. In other words, it would look for the table "suggestion_votes". If you want to override the associated table name, you can add this property to your model:
protected $table = 'suggestions_votes';
If you are actually creating a pivot table for the models "Suggestion" and "Vote", then Laravel will by convention join the two related model names in alphabetical order. In other words, it will look for the pivot table "suggestion_vote". You can override this though when you define the relationship. For example:
return $this->belongsToMany('App\Suggestion', 'suggestions_votes');
Where 'App\Suggestion' would be fully namespaced path to your Suggestion class.
It depends. You can make any name work.
If you have no control of the database, the model 'should' be SuggestionsVote
If you do have control over the database, I would rename the table to suggestion_votes and the model name would be SuggestionVote
