$posts = Post::all()->orderby('created_at','desc')->where('usr_id','=',session('LoggedUser'))->get();
return view('admin.profile',compact('userInfo' , 'posts'));
i am making a custom auth for a journal activity but i cant sort the content i shows this error
"Method Illuminate\Database\Eloquent\Collection::orderby does not exist. "
$posts = Post::where('usr_id','=',session('LoggedUser'))->orderby('created_at','desc')->get();
True query like that. When you take all() already query done.
Change it to:
$posts = Post::where('usr_id','=',session('LoggedUser'))->orderby('created_at','desc')->get();
you cant use all() and orderBy because all() does not allow the modification of the query.
I believe this might be because you typed orderby instead of orderBy (notice the uppercase). See laravel orderBy documentation if needed.
Plus, as mentionned by other, don't use all() if you need to do other thing (where clause, order by, etc) in you query.
Change the orderby to orderBy. This could be the reason you are getting the error.
$posts = Post::all()->orderBy('created_at', 'DESC')->where('usr_id','=',session('LoggedUser'))->get();
return view('admin.profile',compact('userInfo' , 'posts'));
Or...
If you want to get specific number of posts you can do it this way to avoid using the Post::all
$posts = Post::orderBy('created_at', 'DESC')->where('usr_id','=',session('LoggedUser'))->paginate(5);
return view('admin.profile',compact('userInfo' , 'posts'));
Yeah this is pretty confusing and just got me as well.
The actual problem isn't the capitilization typo (orderby versus orderBy) but rather the fact that you're using ->all() instead of just Model::orderBy()->...
The moment you use ->all() the object is transformed to another type of collection object and the normal methods one would expect do not exist.
In this case you should rather use sortBy().

I have a model called CustomerInfo and i am trying to update it. update returns true but the changes are not reflecting on my db.
$customerInfo = CustomerInfo::where('machine_name',$username)->firstOrFail();
$result = $customerInfo->update($data);
$data varaible is a array having key value pair.
Also tried the following
$customerInfo = CustomerInfo::where('machine_name',$username)->update($data);
make sure $data variable that you want update record by its values, not be same with that record.
in this case, you don't have sql error but return of update will be zero.
Solved my questions.
Thanks Luciano.
i started eloquent manual db transaction and forgot to commit it at the end
DB::beginTransaction();//did this
$customerInfo = CustomerInfo::where('machine_name',$username)->firstOrFail();
$result = $customerInfo->update($data);
DB::Commit() //forgot to implement this part.
$result = $customerInfo->update($data);
$result variable will return only the boolean value. Try to return $customerInfo i.e.
return response()->json($customerInfo);
This will help you to find the actual problem and make sure the CustmerInfo model contains fillable properties and the $data variable contains all the information.
Try to use dd() like below to identify the issue:
dd($variable);
I have a query that needs to use a custom function like is showed below.
The problem is that one of the parameters is a value of another field from the same query.
The function is "calcula_distancia" and "$ofps[0]->latitude" and "$ofps[0]->longitude" are fields from a previus query.
The function needs 4 parameters and the last two are field from $necps that is beeing selected, but I can not retrieve the value from it using just 'participantes.latitude' or even without cotes. It passes a string only, to the function.
So, how can I pass the value from this fields beeing selected to the function?
Tryed to use RAW but not work.
Sorry for the big question. thanks! :-)
use App\Classes\MinhasFuncoes;
$mf = new MinhasFuncoes();
$necps = DB::table('necessidades_part')->where('necessidades_part.id_part',"<>",$id_part)
->where(function($query) use ($searchValues){
foreach ($searchValues as $value) {
if(strlen($value)>3){
$query->orwhere('obs','like','%'.($value).'%')
->orwhere('necessidades.descricao','like','%'.($value).'%')
->orwhere('categorias.descricao','like','%'.($value).'%');
}
}
})
->join('participantes','necessidades_part.id_part','=','participantes.id')
->join('necessidades','necessidades_part.id_nec','=','necessidades.id')
->join('categorias','necessidades.id_cat','=','categorias.id')
->join('unidades','necessidades.id_unid','=','unidades.id')
->select('participantes.id as id_part','participantes.nome_part','participantes.latitude',
'participantes.longitude','participantes.nome_part','necessidades_part.id as id_nec_part',
'necessidades_part.id_nec','necessidades_part.quant','necessidades_part.data',
'necessidades_part.obs','necessidades.descricao as desc_nec',
'categorias.descricao as desc_cat','unidades.descricao as desc_unid',
$mf->calcula_distancia($ofps[0]->latitude,$ofps[0]->longitude,'participantes.latitude',
'participantes.longitude').' as distancia')
->orderBy('data','desc')
->paginate(10);
you can not execute your PHP function inside of your DB query. you should use MySQL function instead of that or you should fetch results from the database then map your result just in PHP
lets say I have 7 columns in table, and I want to select only two of them, something like this
SELECT `name`,`surname` FROM `table` WHERE `id` = '1';
In laravel eloquent model it may looks like this
Table::where('id', 1)->get();
but I guess this expression will select ALL columns where id equals 1, and I want only two columns(name, surname). how to select only two columns?
You can do it like this:
Table::select('name','surname')->where('id', 1)->get();
Table::where('id', 1)->get(['name','surname']);
You can also use find() like this:
ModelName::find($id, ['name', 'surname']);
The $id variable can be an array in case you need to retrieve multiple instances of the model.
By using all() method we can select particular columns from table like as shown below.
ModelName::all('column1', 'column2', 'column3');
Note: Laravel 5.4
You first need to create a Model, that represent that Table and then use the below Eloquent way to fetch the data of only 2 fields.
Model::where('id', 1)
->pluck('name', 'surname')
->all();
Also Model::all(['id'])->toArray() it will only fetch id as array.
Get value of one column:
Table_Name::find($id)->column_name;
you can use this method with where clause:
Table_Name::where('id',$id)->first()->column_name;
or use this method for bypass PhpStorm "Method where not found in App\Models":
Table_Name::query()->where('id','=',$id)->first()->column_name;
in query builder:
DB::table('table_names')->find($id)->column_name;
with where cluase:
DB::table('table_names')->where('id',$id)->first()->column_name;
or
DB::table('table_names')->where('id',$id)->first('column_name');
last method result is array
You can use get() as well as all()
ModelName::where('a', 1)->get(['column1','column2']);
From laravel 5.3 only using get() method you can get specific columns of your table:
YouModelName::get(['id', 'name']);
Or from laravel 5.4 you can also use all() method for getting the fields of your choice:
YourModelName::all('id', 'name');
with both of above method get() or all() you can also use where() but syntax is different for both:
Model::all()
YourModelName::all('id', 'name')->where('id',1);
Model::get()
YourModelName::where('id',1)->get(['id', 'name']);
To get the result of specific column from table,we have to specify the column name.
Use following code : -
$result = DB::Table('table_name')->select('column1','column2')->where('id',1)->get();
for example -
$result = DB::Table('Student')->select('subject','class')->where('id',1)->get();
use App\Table;
// ...
Table::where('id',1)->get('name','surname');
if no where
Table::all('name','surname');
If you want to get a single value from Database
Model::where('id', 1)->value('name');
Also you can use pluck.
Model::where('id',1)->pluck('column1', 'column2');
You can use Table::select ('name', 'surname')->where ('id', 1)->get ().
Keep in mind that when selecting for only certain fields, you will have to make another query if you end up accessing those other fields later in the request (that may be obvious, just wanted to include that caveat). Including the id field is usually a good idea so laravel knows how to write back any updates you do to the model instance.
You can get it like
`PostModel::where('post_status', 'publish')->get(['title', 'content', 'slug', 'image_url']`)
link
you can also used findOrFail() method here it's good to used
if the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these method not give a 500 error..
ModelName::findOrFail($id, ['firstName', 'lastName']);
While most common approach is to use Model::select,
it can cause rendering out all attributes defined with accessor methods within model classes. So if you define attribute in your model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
/**
* Get the user's first name.
*
* #param string $value
* #return string
*/
public function getFirstNameAttribute($value)
{
return ucfirst($value);
}
}
And then use:
TableName::select('username')->where('id', 1)->get();
It will output collection with both first_name and username, rather than only username.
Better use pluck(), solo or optionally in combination with select - if you want specific columns.
TableName::select('username')->where('id', 1)->pluck('username');
or
TableName::where('id', 1)->pluck('username'); //that would return collection consisting of only username values
Also, optionally, use ->toArray() to convert collection object into array.
If you want to get single row and from the that row single column, one line code to get the value of the specific column is to use find() method alongside specifying of the column that you want to retrieve it.
Here is sample code:
ModelName::find($id_of_the_record, ['column_name'])->toArray()['column_name'];
If you need to get one column calling pluck directly on a model is the most performant way to retrieve a single column from all models in Laravel.
Calling get or all before pluck will read all models into memory before plucking the value.
Users::pluck('email');
->get() much like ->all() (and ->first() etc..) can take the fields you want to bring back as parameters;
->get/all(['column1','column2'])
Would bring back the collection but only with column1 and column2
You can use the below query:
Table('table')->select('name','surname')->where('id',1)->get();
If you wanted to get the value of a single column like 'name', you could also use the following:
Table::where('id', 1)->first(['name'])->name;
For getting multiple columns (returns collection) :
Model::select('name','surname')->where('id', 1)->get();
If you want to get columns as array use the below code:
Model::select('name','surname')->where('id', 1)->get()->toArray();
If you want to get a single column try this:
Model::where('id', 1)->first(['column_name'])->column_name;
I followed doctrine documnetation to get started. Here is the documentation.
My code is
$User = Doctrine_Core::getTable("User")->find(1);
when I access relations by $User->Phonenumbers, it works. When I convert User object to array by using toArray() method, it does not convert relations to array. It simply display $User data.
Am I missing something?
By using the find method you've only retrieved the User data which is why the return of toArray is limited to that data. You need to specify the additional data to load, and the best place to do this is usually in the original query. From the example you linked to, add the select portion:
$q = Doctrine_Query::create()
->select('u.*, e.*, p.*') // Example only, select what you need, not *
->from('User u')
->leftJoin('u.Email e')
->leftJoin('u.Phonenumbers p')
->where('u.id = ?', 1);
Then when toArray'ing the results from that, you should see the associated email and phonenumber data as well.
I also noticed an anomaly with this where if you call the relationship first then call the ToArray, the relationship somehow gets included. what i mean is that, taking your own eg,
$User = Doctrine_Core::getTable("User")->find(1);
$num= $User->Phonenumbers->office; // assumed a field 'office' in your phone num table
$userArray = $user->toArray(true);
In the above case, $userArray somehow contains the whole relationship. if we remove the $num assignment it doesn't.
am guessing this is due to doctrine only fetching the one record first, and it's only when you try to access foreign key values that it fetches the other related tables
