		0 ignored issues – show Bug introduced 2020-03-10 16:40 UTC by Report Bug Copy Issue Report Accessing `translation` on the interface `BBSLab\NovaTranslation\M...ontracts\IsTranslatable` suggest that you code against a concrete implementation. How about adding an `instanceof` check? If you access a property on an interface, you most likely code against a concrete implementation of the interface.

		0 ignored issues – show Bug introduced 2020-03-10 16:40 UTC by Report Bug Copy Issue Report The method `get` does only exist in `Illuminate\Database\Eloquent\Builder`, but not in `BBSLab\NovaTranslation\Models\Translation`. It seems like the method you are trying to call exists only in some of the possible types. Let’s take a look at an example: class A { public function foo() { } } class B extends A { public function bar() { } } /** * @param A\|B $x / function someFunction($x) { $x->foo(); // This call is fine as the method exists in A and B. $x->bar(); // This method only exists in B and might cause an error. } Available Fixes Add an additional type-check: /* * @param A\|B $x / function someFunction($x) { $x->foo(); if ($x instanceof B) { $x->bar(); } } Only allow a single type to be passed if the variable comes from a parameter: function someFunction(B $x) { /* ... */ } Loading history...
