PUT method throws BadMethodCallException - php

Question

I'm learning Laravel from Lacast and i'm trying to create a CRUD application.I've implemented the index,show,create and store correctly,but with the edit form when i try to submit data it's throwing BadMethodCallException.
Here are my routes
Route::get('/projects','ProjectsController#index');
Route::get('/projects/{id}','ProjectsController#show')->where('id','[0-9]+');
Route::get('/create','ProjectsController#create');
Route::post('/projects','ProjectsController#store');
Route::get('/projects/{id}/edit','ProjectsController#edit')->where('id','[0-9]+');
Route::put('/projects/{id}','ProjectsController#update')->where('id','[0-9]+');
Route::delete('/projects/{id}','ProjectsController#destroy');
Here is the edit form:
#extends('template');
#section('content')
<h2>Create new project</h2>
<p>/projects/{{ $project->id }}</p>
<form method="POST" action="/projects/{{ $project->id }}">
{{ method_field('PUT') }}
{{ csrf_field() }}
<div>
<input value="{{ $project->title }}" type="text" name="title" id="title" placeholder="Project title">
</div>
<div>
<textarea name="description" placeholder="Enter the project description">{{ $project->description }}</textarea>
</div>
<div>
<button type="submit">Update project</button>
</div>
</form>
#endsection
The controller code:
public function edit($id){
$project= Project::find($id);
return view('projects.edit',compact('project'));
}
public function update($id){
$project= Project::find($id);
$project->title=request('title');
$project->description('description');
$project->save();
return redirect('/projects');
}
The edit form displays as expected with data coming from the database,after submit i get the following error page:
With the example of the instructor the code has worked perfectly,and before using the PUT either on my form and in my controller i used PATCH like the instructor but always the same result.

The error is pretty straightforward.
public function update($id){
$project= Project::find($id);
$project->title=request('title');
$project->description('description'); // You don't have a method description()
$project->save();
return redirect('/projects');
}
This is what you probably meant to do:
public function update($id)
{
$project= Project::find($id);
$project->title = request('title');
$project->description = request('description');
$project->save();
return redirect('/projects');
}
