Laravel 5 Has One Relationship with Form Binding

问题

I have spent a pretty good two days on something so simple and small. I have a model called User which has one user note relationship.

On the User model's side I have a belongsTo relationship defined and then the user's model defines a hasOne side of relationship.

The form I am using binds to $user model meanwhile the UserNote model has its own table that maps to the user with user_id.

I have been trying to get what is shown below right;

{{ Form::textarea($user->notes, null , [ 'class' => 'form-control', 'placeholder' => 'Note Content']) }}

Somebody out there to help me figure this out?b All I need is to be able to add a note and if a user has no note yet I should not be getting errors because if I do as shown below I get an error:

{{ Form::textarea('UserNote[content]',... }}

Your advice would be appreciated.

class User{
 ...
 public function note()
 {
    return $this->belongsTo(UserNote::class);
  }
}

class UserNote{
 protected $fillable = ['content', 'user_id'];
...
public function user()
{
    return $this->hasOne(User::class, 'user_id');
  }
}

Surely the user_id in $fillable shouldn't be there in the first place because this only means I can update this table manually whereas I want everything done automatically from controller to form binding.

回答1:

First of all, you're doing the relationship wrong.

User hasOne UserNote
UserNote belongsTo User

So, you've to swap the relations on those corresponding models.
Secondly, The form's textarea has the parameter list like:

public function textarea($name, $value = null, $options = []){}

So, the first parameter is obviously the form_name. second parameter will be the value of the input. You're doing this wrong.
In your case, that should be ( as I think )

{{ Form::textarea('user_note', $user->note , [ 'id' => 'user_note', 'class' => 'form-control', 'placeholder' => 'Note Content']) }}

Edit
The property note is the method name, you're previously writing like notes, the method didn't exist. Edit Ends
Hope this helps. Happy coding!
