$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().

Can anybody please help me achieving the result and solve my problem. I'm working in codeigniter where i want to fetch records from a mysql database using OR statement. I'm using custom model extension by Avenirer. I want to know how to use or operator in where function of this MY_MODEL:
https://github.com/avenirer/CodeIgniter-MY_Model/blob/version-3.0/core/MY_Model.php
You can do it in two ways.
You use or_where
$this->db->where('column1', 'like');
$this->db->or_where('column2', 'like');
or you can write both in a where
$this->db->where("(column1='like' OR column2='like')");
Hope it helps you out.
I can't give you an exact answer for your code, because I don't know exactly where the error is. If you could write the line to it, that would be useful.
I figured out the answer by studying the code in MY_MODEL file.
The right way to write where with OR clause was to use their special syntax.
As per the code in the file MY_MODEL, it states the supported arguments for where function, which are:
where($field_or_array = NULL, $operator_or_value = NULL, $value = NULL, $with_or = FALSE, $with_not = FALSE, $custom_string = FALSE)
Setting the 4th argument true will change the final syntax to OR statement.
Right statement in my case will be:
$this->Table_model->where('field1','value1')->where('field2','value2',null,true)->get_all();
This statement will be processed to following SQL statement.
SELECT * FROM Table WHERE 'field1'='value1' or 'field2'='value2'
Thanks all for their cooperation.
Link for table
link for expected result, after group by 'receiver_user_id' and recent time
I have used the laravel query:-
$sub = BaseMessagesHistory::select('messages_history.*')->orderBy('created_at','DESC');
$chats = DB::table(DB::raw("({$sub->toSql()}) as sub"))
->select('receiver_user_id',DB::raw('max(created_at) as recent_time'))
->where('sender_user_id',$userId)
->orwhere('receiver_user_id',$userId)
->groupBy('receiver_user_id')
->havingRaw('max(created_at)')
->latest()->get();
Result:-
I am getting only "recent_time" and "receiver_user_id"
Expectation:- I need whole data from table not only "recent_time" and "receiver_user_id"
So can you please help me out
It will return you only those columns which you mentioned in the select().
In your query, you mentioned only receriver_user_id and recent_time.
->select('receiver_user_id',DB::raw('max(created_at) as recent_time'))
You need to add all those columns in select() which you need.
Or try this ->select('sub.*',DB::raw('max(created_at) as recent_time'))
Hope this helps. Ask in case of doubt.
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;
Here is my controller code;
$temp_table_data = $temp_table
->setTempTable($generated_temp_table)
->newQuery()
->with(['payment' => function ($query) use ($column_values) {
$query->select($column_values);
}])->get();
My toSql query is right below it;
$sql = str_replace(['%', '?'], ['%%', "'%s'"], $temp_table->toSql());
$fullSql = vsprintf($sql, $temp_table->getBindings());
print_r($fullSql);
My code prints out;
select * from `selected_postcodes_1434968225_1`
Where are the details of the payments information that I am "with"ing? If I want to print out the raw query now, to show another developer, to get some help, what am I supposed to do here?
The eager loaded relationships are fetched in a separate query. You can use DB::getQueryLog() to get all run queries. Note that you have to enable it first using with DB::enableQueryLog().
Another alternative is the Laravel Debugbar package that shows you all queries and much more.
