Laravel: Validation unique on update still failing all the time - php

Question

I've an update form that contains an image and other data to be updated I changed the default route key to use the name instead of the default key which is the ID and I made a separate form request to validate my requests It works fine when posting new record unfortunately it keeps failing with the name field which is unique field; I've checked all threads on github and in stackoverflow with no use although I have the same project in laravel 5.5 and it works fine and now I'm stuck with laravel 6
hereis my form
let data = new FormData();
data.append('name', this.channel.name);
data.append('base_color', this.channel.baseColor);
data.append('complementary_color', this.channel.complementaryColor);
if (this.file){
data.append('avatar', this.file);
}
data.append('_method', 'PUT');
axios.post(`/dashboard/channels/${this.channel.name}`, data).then(resp => {
this.$parent.$emit('channel_updated', resp.data);
}).catch(error => {
flash(error.response.data, 'danger', 'backEndStyle');
});
and here is my route
Route::resource('/dashboard/channels', 'ChannelController');
and here is my form request
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class ChannelRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'name' => 'required|unique:channels,name,'. $this->id,
'base_color' => 'required',
'complementary_color' => 'required',
];
}
}
here is my controller for update method
public function update(Channel $channel, ChannelRequest $request)
{
$channel->update([
'name' => $request->name,
'bg_base_color' => $request->base_color,
'bg_complementary_color' => $request->complementary_color,
]);
return response($channel->fresh(), 200);
}

Answer 1

Use the ignore constraint to ignore the current model when validating unique
public function rules()
{
return [
'name' => ['required', Rule::unique('channels')->ignore($this->route('channel'))],
'base_color' => 'required',
'complementary_color' => 'required',
];
}
