how can I access to another column in blade - php

Question

I have the id in a blade and I want to access to another column.
I have $article->country_id which gives access to the id of the foreign key country.
How can I find the record using id and then get access to country->name.
I have done the things below but it doesn't work as I have explained.
Here is the blade
#foreach($articles as $article)
<div class="col-md-12">
کشور:<h4 class ="post-title">{{route('article.whichCountry',$article->country_id)}}</h4>
</div>
#endforeach
here is web.php
Route::get('article/whichCountry/{country}',[
'uses' => 'ArticleController#whichCountry',
'as' => 'article.whichCountry'
]);
and here is whichCountry in ArticleController
public function whichCountry($id){
$country = country::where('id',$id)->first();
return $country->name;
}
The point is that it doesn't call the function whichCountry
and prints:
http://127.0.0.1:8000/article/whichCountry/10
Thank you very much for your response in advance!

Answer 1

Your route access needs to be like below, giving value for {country} parameter.
{{ route('article.whichCountry',['country' => $article->country_id]) }}
Second, instead of where in your controller method, if Id is the primary key, you can just do:
Country::find($country);
Also, change your function definition like below for the parameter value filling
public function whichCountry($country){

Answer 2

This is very simple to implement this. First check your Controller is getting the id properly. Then use find method
Your route should be like this
{{route('article.whichCountry',['id'=>$article->country_id])}}
And in your controller you have to use like this
public function whichCountry($id){
$country = country::where('id',$id)->first();
return $country->name;
}
In your web.php looks like this
Route::get('article/whichCountry/{id}',[
'uses' => 'ArticleController#whichCountry',
'as' => 'article.whichCountry'
]);
