How to properly update a model on laravel? Method Illuminate\Database\Eloquent\Collection::update does not exist

Question

I made a page for a user to update his company information, all companies default values are null, when a user is created. When a user fills the information, i get this error:

 Method Illuminate\Database\Eloquent\Collection::update does not exist 

I am sure this error is because of my CompanyController@edit

     public function edit(Request $request)
{
    $this->validate($request, [
        'company_name' => 'alpha|max:50',
        'phone' => 'integer|max:50',
        'gst_hst_number' => 'integer|max:50',
        'country' => 'alpha|max:50',
    ]);

    $companies = Company::where('id', Auth::user()->id)->get();

    $companies->update([
        'company_name' => $request->input('company_name'),
        'phone' => $request->input('phone'),
        'gst_hst_number' => $request->input('gst_hst_number'),
        'country' => $request->input('country')
    ]);

    return redirect()->route('company.index')->with('info', 'Company information was updated.');
}

I am stuck quite some time on this issue, would gladly apriciate help and information how to properly update my company models fillable fields.

Answer 1

‌As the error message says, you are using the update method on a collection , you have to change the select query to this:

$companies = Company::where('id', Auth::user()->id)->first();

Because the get() method returns a collection, not a single record.

Answer 2

Try this. ->get() is for multiple collections here you can directly update your records.

$companies = Company::where('id', Auth::user()->id)->update([
    'company_name' => $request->input('company_name'),
    'phone' => $request->input('phone'),
    'gst_hst_number' => $request->input('gst_hst_number'),
    'country' => $request->input('country')
]);;

Answer 3

Your using update method on collection, but collection doesn't have update method,

what you need is remove the get() , so you can use update method on eloquent builder:

$companies = Company::where('id', Auth::user()->id);
$companies->update([
        'company_name' => $request->input('company_name'),
        'phone' => $request->input('phone'),
        'gst_hst_number' => $request->input('gst_hst_number'),
        'country' => $request->input('country')
]);
