I am trying to send posts to Laravel Api. and I want to paginate them and also arrange them according to the latest. But I am gettting an error Method Illuminate\Database\Eloquent\Collection::paginate does not exist. in file
Here is my Api Code
public function index()
{
$posts = Post::with('comment', 'user')
->latest()
->get()
->paginate(5);
return response()->json([
'status'=>200,
'posts'=>$posts
]);
}
Kindly help. Thank you
You don't need to call the get method, this is enough:
$posts = Post::with('comment', 'user')
->latest()
->paginate(5);
So I'm a total newbie in laravel and I don't know if it can be done but I saw that in the controller I can display data of a specific 'id' with this in my api.php:
Route::get('books/{id}', 'App\Http\Controllers\BooksController#getBookById');
And this in my BookController.php :
public function getBookByAuthor($id) {
$book = Books::find($id);
if (is_null($book)){
return response()->json(['message' => 'Book Not Found.'], 404);
}
return response()->json($book::find($id), 200);
}
I'm using Angular for the front and I have a searchbar to search by 'title' of a book, so in my database I have a column 'title' and I want to fetch data by 'title' instead of 'id'.
Is it possible ? And if yes how ?
I'm thinking you're wanting to retrieve the book based on user input...? You can inject the request in your method. Also you don't need to explicitly handle 404 and response codes.
use Illuminate\Http\Request;
use App\Models\Book;
public function getBookByAuthor(Request $request): Response
{
$input = $request->validate([
'title' => 'required|alpha_dash' // validate
]);
return Book::where('title', 'like', "%{$input['title']}%")
->firstOrFail();
}
Validation docs
In laravel controller validation getting failed, please help.
Repository: https://github.com/dhawlesudhir/basic_app.git
ProductController.php:
protected function validateRequest()
{
return request()->validate([
'name' => 'required|min:10|max:255',
'price' => 'required|integer|min:100',
'category_id' => 'required|exists:categories,id'
]);
}
public function store()
{
$data = $this->validateRequest();
$product = Product::create($data);
return new ProductResource($product);
}
api.php:
Route::apiResource('/products', ProductController::class);
Laravel throwing validation because you haven't set json in postman.
I can see currently you have set Text.
Set type to json like in screenshot
Otherwise Laravel receives empty array from request()->all()
Also make sure to set header Accept:application/json .
I can't get the data from the database. Getting an error:
ErrorException (E_ERROR)
Undefined variable: user
(View:/Users/alex/Desktop/sites/tj/resources/views/user/submissions.blade.php)
Controller:
public function __construct()
{
$this->middleware('auth', ['except' => ['getById',
'getByUsername', 'submissions', 'comments', 'showSubmissions',
'showComments']]);
}
and
public function showSubmissions($username)
{
$user = new UserResource(
User::withTrashed()->where('username', $username)->firstOrFail(),
true
);
$submissions = SubmissionResource::collection(
Submission::whereUserId($user->id)
->withTrashed()
->orderBy('created_at', 'desc')
->simplePaginate(15)
);
return view('user.submissions', compact('user', 'submissions'));
}
View:
{{ $user->username }}
API:
Route::get('/user', 'UserController#getByUsername');
I need get information about user (username).
What is the problem and where is the error?
Based on your comment you have this route:
Route::get('/submission', function () {
return view('user.submissions');
});
When you are loading this view, you are not passing the user object to it. Then when the view is running, it is trying to access a variable that does not exist.
To fix this, you need to pass a variable to the view you are loading. For example, you could do something like this:
Route::get('/submission', function () {
return view('user.submissions', ['user' => auth()->user()]);
});
Note that you can change how you get the user instance depending on your use case. I am just getting the authenticated user to demonstrate the principle.
I am using craftable to generate an admin panel for my app.
I have an Organisation model that belongs to an Organisation Type model.
In the index listing, I want to be able to display the Organisation Type name rather than the _id. To do this, I have to modify this query, to eager load the relationship using the 'with' method.
The method signature for the listing is:
public static function processRequestAndGet($request, $columns = array(), $searchIn = null, $modifyQuery = null, $locale = null)
and the index method is:
$data = AdminListing::create(Organisation::class)->processRequestAndGet(
// pass the request with params
$request,
// set columns to query
['id', 'organisation_type_id', 'name', 'active'],
// set columns to searchIn
['id', 'name']
);
if ($request->ajax()) {
return ['data' => $data];
}
return view('admin.organisation.index', ['data' => $data]);
Craftable, provides a modifyQuery method to, but i'm not sure how to use it:
public function index(IndexMovie $request)
{
$data = AdminListing::create(Movie::class)
->modifyQuery(function($query) use ($request){
if ($request->has('author_id')) {
$query->where('author_id', $request->author_id);
}
})
->get();
Can someone help me use the callback to modify the query so that I can include the related table data?
Okay so I've came across the exact same problem and I'd like to share my way of doing it.
craftable uses a processRequestAndGet function that takes as a 4th parametre the intended callable query. So when you need to use that parametre rather than trying to access the modifyQuery function directly.
$data_r = AdminListing::create(Organisation::class)
->processRequestAndGet(
// pass the request with params
$request,
// set columns to query
['id', 'organisation_type_id', 'name', 'active'],
// set columns to searchIn
['id', 'name'],
function($query) use ($request){
if ($request->has('author_id')) {
$query->where('author_id', $request->author_id);
}
}
);
You were almost right, just pass the intended callback inside your processRequestAndGet and voilà.
