Laravel unsupported get method

Question

I have some problems with getting some info from database in Laravel. I'm trying to use where method and specify id that I need to but I always have error like

Symfony\Component\HttpKernel\Exception\MethodNotAllowedHttpException: The GET method is not supported for this route. Supported methods: POST.

Here is the code Controller

public function select_category($category_id){
        $products = Products::where('category_id', $category_id)->get();

        return $products;
    }

Api

Route::get('products/{category_id}', 'ProductsController@select_category');

When I delete $category_id and where, only have like Products::all(); works fine, but need to specify where to search.

Link how I specify the $category_id is http://localhost:8000/api/products/?category_id=16

Answer 1

The log indicate that there is a route error, it has nothing to do with your Eloquent model

Check if you have another route conflicting with that one

---

Edit : After seeing your URL, you should use " http://localhost:8000/api/products/16 " rather than " http://localhost:8000/api/products/?category_id=16 "

The second one try to access your post route "Route::post('products'..." because, to Laravel, everything after the "?" is a parameter and isn't used in route detection

Answer 2

Make sure that in your routes file, below the definition of this route you don't have similar endpoint set for a post method. So you most probably have:

Route::post('products/something', 'ProductsController@store');

this will override the previously defined one.

To prevent this, you can modify your current route to this:

Route::get('products/{category_id}', 'ProductsController@select_category')->where('category_id', '[0-9]+');

Answer 3

change your URL:

http://localhost:8000/api/products/16

also change in a view file:

<a href="{{ URL::to('products/'. $yourchategoryid ) }}">product</a>

Answer 4

I think it should be

 public function select_category(Request $request, $category_id){
        $products = Products::where('category_id', $category_id)->get();

        return $products;
    }

if url is

http://localhost:8000/api/products/16

and if url is

http://localhost:8000/api/products/?category_id=16

function should be

public function select_category(Request $request){
            $products = Products::where('category_id', $request->input('category_id'))->get();

        return $products;
    }

first parameter of the function should be Request class instance
