I am having a datetime input in my form and the user will select date and time from that input. But when inserting, the data should be only date and time, but T also getting inserted? How not to insert it?
Here is the migration code:
public function up()
{
Schema::create('competitions', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->text('desc');
$table->float('entry_fees');
$table->varchar('start_date_time',50);
$table->Date('end_date_time',50);
$table->integer('status');
$table->string('date_time');
$table->timestamps();
});
}
The columns name are start_date_time and end_date_time?
If its just datetime can you not set your columns like this then carbon parse on creating
public function up()
{
Schema::create('competitions', function (Blueprint $table) {
$table->id();
$table->string('title');
$table->text('desc');
$table->float('entry_fees');
$table->datetime('start_date_time');
$table->datetime('end_date_time');
$table->integer('status');
$table->string('date_time');
$table->timestamps();
});
}
first your columns should be dateTime type in your table and then
you can change its format with laravel carbon
$createdAt = Carbon::parse($item['start_date_time']);
Then you can use
$start_date = $createdAt->format('d/m/Y H:i:s');

I am running a databse migration in laravel 5.8 and I am getting the following error:
Illuminate\Database\QueryException : SQLSTATE[HY000]: General error: 1005 Can't create table cartorque.likes (errno: 150 "Foreign key constraint is incorrectly formed") (SQL: alter table likes add constraint likes_
post_id_foreign foreign key (post_id) references posts (id) on delete cascade on update cascade)
Here are how my tables are setup
User Table:
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
Posts Table
Schema::create('posts', function (Blueprint $table) {
$table->bigIncrements('id');
$table->timestamps();
$table->string('title', 500);
$table->longText('content');
$table->tinyInteger('privacy')->default('0');
$table->string('location', 250);
$table->bigInteger('longitude');
$table->bigInteger('latitude');
$table->bigInteger('user_id')->unsigned()->index();
$table->string('slug', 250);
});
Schema::table('posts', function (Blueprint $table) {
$table->foreign('user_id')->references('id')->on('users')
->onDelete('cascade')
->onUpdate('cascade');
});
Likes Table
Schema::create('likes', function (Blueprint $table) {
$table->bigIncrements('id');
$table->timestamps();
$table->unsignedBigInteger('user_id');
$table->unsignedBigInteger('post_id');
$table->boolean('like');
});
Schema::table('likes', function (Blueprint $table) {
$table->foreign('post_id')->references('id')->on('posts')
->onDelete('cascade')
->onUpdate('cascade');
});
Schema::table('likes', function (Blueprint $table) {
$table->foreign('user_id')->references('id')->on('users')
->onDelete('cascade')
->onUpdate('cascade');
});
The Likes table is to have 2 foreign keys user_id and post_id. It works fine on user_id but I get the error on the post_id column
Found the issue and it was the posts table not being created. This happened because the order of the migration files. The likes foreign key creation was occurring prior to the posts table being created. I change the order of the migration files.
I am new to laravel. I have a table:
students_attendance.
In students_attendance I have a column named class_id, which refers to the students_classes table that also includes the class_id and class_name for each student.
In the frontend table I am getting the values from students_attendance table so the class_id is available, but what I need is the class_name.
How I can get the class_name?
//Migration for students_attendance
public function up()
{
Schema::create('students_attendances', function (Blueprint $table) {
$table->increments('id');
$table->integer('class_id')->index()->unsigned()->nullable();
$table->string('student_id');
$table->string('first_name');
$table->string('last_name');
$table->string('attendance');
$table->timestamps();
});
}
//Migration for students_classes
public function up()
{
Schema::create('students_classes', function (Blueprint $table) {
$table->increments('id');
$table->string('class_name');
$table->string('class_fee');
$table->string('class_teacher');
$table->timestamps();
});
}
//Students Class Model
class StudentsClass extends Model
{
protected $fillable = [
'class_name',
'class_fee',
'class_teacher'
];
public function students() {
return $this->hasMany('App\Students');
}
}
//Students Attendance Model
class StudentsAttendance extends Model
{
protected $fillable = [
'class_id',
'student_id',
'first_name',
'last_name',
'attendance'
];
public function studentsClass() {
return $this->belongsTo('App\StudentsClass');
}
}
From a StatusAttendance variable you can access the class name with $attendance->studentClass->class_name.
Assuming you have the class_id and you want to get the name of the associated class, you can simply do this:
$class = StudentsClass::find($class_id);
$class->class_name; // Outputs the name
I have development custom project where have database tables:
users
candidates
companies
scopes
skills
Users table:
Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('nickname')->unique();
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->boolean('type')->default(0); // 0 = candidate and 1 = company
$table->rememberToken();
$table->timestamps();
});
Candidates table:
Schema::create('candidates', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('user_id');
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->string('name')->nullable();
$table->string('lastname')->nullable();
$table->string('surname')->nullable();
$table->text('about')->nullable();
$table->timestamps();
});
Companies table:
Schema::create('companies', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('user_id');
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->unsignedInteger('logo');
$table->foreign('logo')
->references('id')
->on('images')
->onDelete('cascade');
$table->string('name')->nullable();
$table->text('about')->nullable();
$table->string('website')->nullable();
$table->integer('employees')->nullable();
$table->timestamps();
});
Scopes table:
Schema::create('scopes', function (Blueprint $table) {
$table->increments('id');
$table->string('name')->unique();
$table->timestamps();
});
Skills table:
Schema::create('skills', function (Blueprint $table) {
$table->increments('id');
$table->string('name')->unique();
$table->timestamps();
});
Here any users type have scopes and skills. I can solve this solution with creating one table:
Attributes table:
Schema::create('attributes', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('user_id');
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->morphs('model');
$table->timestamps();
});
Example data inside attributes table:
----------------------------------------
| id | user_id | model_id | model_type |
----------------------------------------
| 15 | 176 | 34458 | App\Scope |
----------------------------------------
| 29 | 245 | 17654 | App\Skill |
----------------------------------------
But in this solution there is one bad side for me, this is the repetition of the string name of the model on each line of the record in the table. For example:
Models table:
Schema::create('models', function (Blueprint $table) {
$table->increments('id');
$table->string('name')->unique();
$table->timestamps();
});
Note: It may be impossible to create a module with the name of the Model, so you may need to create it with a different name, for example: Reference
Example data inside models table:
-------------------
| id | name |
-------------------
| 10 | App\Scope |
-------------------
| 11 | App\Skill |
-------------------
After creating the models table, the structure of the attribute table changes to:
Attributes table:
Schema::create('attributes', function (Blueprint $table) {
$table->increments('id');
$table->unsignedInteger('user_id');
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->foreign('model_id')
->references('id')
->on('models')
->onDelete('cascade');
$table->unsignedInteger('content_id');
$table->timestamps();
});
Now how can I create the right relationship inside models to get candidates or company user types skills or scopes?
I have custom relationships inside Users model:
public function candidate()
{
return $this->hasOne(Candidate::class);
}
public function company()
{
return $this->hasOne(Company::class);
}
Now, I need inside Candidate and Company model like this relationships:
public function skills()
{
// Some code here
}
public function scopes()
{
// Some code here
}
In general get users skills or scopes like this:
$user->candidate->scopes
$user->company->skills
If you have another suggestion for solving my problem, please offer your suggestion. If I made a mistake somewhere, correct me if it is possible.
Methink your primary ORM construction error is in this line:
$table->boolean('type')->default(0); // 0 = candidate and 1 = company
This is not solvable with the use of Laravel's ORM. You will have to replace this line with
$table->unsignedInteger('candidate_id')->nullable()->index();
$table->unsignedInteger('company_id')->nullable()->index();
and start from there. As it can either be a candidate or a company, one of the values will be empty. Easy to check. As there are only 2 possible options, a polymorphic relationship is not really needed. Once you get over that check, your ORM hierarchy will outline itself.
You only have to take care that if a candidate becomes a company or visa versa, you make sure the other value gets nullified. This can all be done in Model's mutators or a personalized public function so you don't have to worry about it in the Controllers/Views.
For example $user->choice->scopes; where you add a User Model function getChoiceAttribute()
public function getChoiceAttribute() {
if ($this->candidate) {
return $this->candidate;
}
if ($this->company) {
return $this->company;
}
return null;
}
The same applies to a setter function setChoiceAttribute() in case a candidate becomes a company. This only applies if you save or update a record.
To know in the view if you are working with candidates or companies, just check on $user->choice->getTable();.
I am trying to insert into 2 different tables(House and Contact) using a single method.
public function store(HouseRequest $request){
$dataForm = $request->all();
$house = House::create($dataForm); //Insert into House table
$contact = $house->contact()->create($dataForm['contact']); //Insert into Contact table
return back('dashboard/houses')->with('message', 'Success');
}
Here is my table Contact:
Schema::create('contacts', function (Blueprint $table) {
$table->integer('house_id')->unsigned();
$table->string('name', 255);
$table->char('phone', 11);
$table->timestamps();
$table->foreign('house_id')->references('id')->on('houses')->onDelete('cascade')
}
House Model:
public function contact(){
return $this->hasOne(Contact::class);
}
It works fine (inserts into both tables), but after submitting the form, I got this:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'id' in 'where clause' (SQL: select * from contacts where id = 0 limit 1)
I don't know why it is running the query above. How can I get rid of this error?
You just forgot to add a column for ids add $table->increments('id'); in your migration :
Schema::create('contacts', function (Blueprint $table) {
$table->increments('id');
$table->integer('house_id')->unsigned();
$table->string('name', 255);
$table->char('phone', 11);
$table->timestamps();
$table->foreign('house_id')->references('id')->on('houses')->onDelete('cascade')
}
for some reason i'm getting false when checking if an table exist in my tempdb, yes it does exist :)
tried:
Schema::hasTable('tempdb.dbo.tempreport')
Schema::hasTable('tempdb..tempreport')
this is what i want to do:
if(Schema::hasTable('tempdb.dbo.tempreport') == false){
Schema::create('tempdb.dbo.tempreport', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('airline');
$table->timestamps();
});
}
