Laravel : after adding make:auth getting an error in my login/register page

Question

i've made a laravel newswebsite. i've tried to add auth by doing make:auth, but when i click the button login or register it gives me an error like this:

i dont know where it is coming from. it refers to a function in my controller but i dont know why cause it doesnt need that function at all. i usually dont have errors while adding authorization. is there anyone who's had the same problem or anyone who knows how to fix it?

app.blade.php

It seems to me that the problem actually is in the above line.

$category = Categorie::where('naam',$category)->first();

This line is not returning any data. Try putting dd($category) after this line to check if there is indeed a category with your query.

thanks for the answer btw, it returns 'null'. do you have any idea where i have to search for what to change

Jesus Erwin Suarez Over a year ago

You need to check your request parameter and route

Nabil Farhan Over a year ago

There are 2 variable with the same name ($category). One is passed as a variable. (I meant oversight($category) )... Also after querying you are putting the result in $category variable. This is a very bad practice.

Probably you are trying to access non-existing category, this page should return 404 error.

after $category = Categorie::where('naam',$category)->first();

add line

abort_if(is_null($category), 404);

and it will return 404 error as it must be.

thanks for the solution, it goes to 404 not found but it still doesnt go to the auth login page

I've added a new route to /login and /register in web.php and now everything works!

Try to debug like this,

public function oversight($category){
    try{
        $getCategory = Categorie::where('naam',$category)->first();
        if($getCategory !== null){
            dd("I GOT SELECTED CATEGORY ROW");
        }else{
            dd("I THINK THERE IS NO DATA AVAIALBLE BASED ON WHERE Condition");
        }
        dd("ALL FINE I AM GOING BACK TO VIEW WITH DATA");
    }catch(\Exception $e){
        dd("I GOT THIS ERROR : ".$e->getMessage());
    }
}

I'm sure you'll able to fix problem by this.

As Narbil Farhan stated, the problem is in the line:

$category = Categorie::where('naam',$category)->first();

You seem to get no result from the Categorie table. First problem can be that the table does not exist, note that Laravel searches for the table 'Categories' (Searches for model name + s). You should probably catch the error if there is no data returned, like Nevermind23 suggested.

if(isset($category->id) && $category->id != ""){
$artikels = Artikel::where('category_id', $category->id)->get()
}

Personal note, try to prevent programming in your native language. This is harder for non Dutch speakings to understand your code.

thanks for the solution. about the note, i know i didnt create it myself i gave my colleague the same critique

Zoli · Accepted Answer · 2019-03-01 10:17:47Z

There are multiple solutions:

Solution:

$category = Categorie::where('naam', $category)->first();
if(#category){
//you can get the $artikels belonging to the category
}

In this case, if there are no category with the respective name, $category will be null, and the code inside IF statement will not be executed.

Solution:

$category = Categorie::where('naam', $category)->firstOrFail();
//you can get the $artikels belonging to the category

In this case, if the Category is not found, an Illuminate\Database\Eloquent\ModelNotFoundException will be thrown. If the exception is not caught, a 404 HTTP response is automatically sent back to the user.

Solution: Route model binding - see the documentation

public function oversight(Categorie $category) {
    return view('pages.oversight', ['category'=>$category]);
}

In this case, if there is no category with the respective name/id, a 404 HTTP response is automatically sent back to the user.

Also, I'd suggest you, to create a( most probably OneToMany) relationship between the Categorie and Artikel model. It will make your life much simpler :)
