Unique key validation showing error while updating data in laravel - php

Question

Hi I am creating an application using laravel and i have a model where asset_number field is unique and the validation rules are as follows
MODEL
protected $rules = array
(
'asset_number' => 'required|alpha_dash|min:2|max:12|unique:asset_details,asset_number,{id}',
'asset_name' => 'alpha_space',
'asset_type_id' => 'required',
'shift' => 'required',
);
Here is my controller code for create and edit
CONTROLLER
public function postCreate()
{
// get the POST data
$new = Input::all();
// create a new Assetdetail instance
$assetdetail = new Assetdetail();
// attempt validation
if ($assetdetail->validate($new))
{
// Save the location data
$assetdetail ->asset_number = e(Input::get('asset_number'));
$assetdetail ->asset_name = e(Input::get('asset_name'));
$assetdetail ->asset_type_id = e(Input::get('asset_type_id'));
$assetdetail ->shift = e(Input::get('shift'));
// Was the asset created?
if($assetdetail ->save())
{
// Redirect to the new location page
return Redirect::to("admin/settings/assetdetails")->with('success', Lang::get('admin/assetdetails/message.create.success'));
}
}
else
{
// failure
$errors = $assetdetail->errors();
return Redirect::back()->withInput()->withErrors($errors);
}
// Redirect to the location create page
return Redirect::to('admin/settings/assetdetails/create')->with('error', Lang::get('admin/assetdetails/message.create.error'));
}
public function getEdit($assetdetailId = null)
{
// Check if the location exists
if (is_null($assetdetail = Assetdetail::find($assetdetailId)))
{
// Redirect to the blogs management page
return Redirect::to('admin/settings/assetdetails')->with('error', Lang::get('admin/assetdetails/message.does_not_exist'));
}
//$assetlife = DB::table('asset_details')->where('id', '=', $assetdetailId)->lists('asset_life');
$location_list = array('' => '') + Location::lists('name', 'id');
$assettype_list = array('' => '') + Assettype::lists('asset_type', 'id');
$assignTo_list = array('' => 'Select a User') + User::select(DB::raw('CONCAT(first_name, " ", last_name) AS full_name'), 'id') ->lists('full_name', 'id');
$assetdetail_options = array('' => 'Top Level') + DB::table('asset_details')->where('id', '!=', $assetdetailId)->lists('asset_number', 'id');
return View::make('backend/assetdetails/edit', compact('assetdetail'))->with('assetdetail_options',$assetdetail_options)->with('location_list',$location_list)->with('assettype_list',$assettype_list)->with('assignTo_list',$assignTo_list);
}
public function postEdit($assetdetailId = null)
{
// Check if the location exists
if (is_null($assetdetail = Assetdetail::find($assetdetailId)))
{
// Redirect to the blogs management page
return Redirect::to('admin/settings/assetdetails')->with('error', Lang::get('admin/assetdetails/message.does_not_exist'));
}
$new = Input::all();
/*if ($assetdetail ->asset_number == Input::old('asset_number') &&
{
$assetdetail ->asset_number = e(Input::get('asset_number'));
}*/
if ($assetdetail->validate($new))
{
// Update the asset data
$assetdetail ->asset_number = e(Input::get('asset_number'));
$assetdetail ->asset_name = e(Input::get('asset_name'));
$assetdetail ->asset_type_id = e(Input::get('asset_type_id'));
$assetdetail ->shift = e(Input::get('shift'));
// Was the asset created?
if($assetdetail->save())
{
// Redirect to the saved location page
return Redirect::to("admin/settings/assetdetails/$assetdetailId/edit")->with('success', Lang::get('admin/assetdetails/message.update.success'));
}
}
else
{
// failure
$errors = $assetdetail->errors();
return Redirect::back()->withInput()->withErrors($errors);
}
// Redirect to the asset management page with error
return Redirect::to("admin/settings/assetdetails/$assetdetailId/edit")->with('error', Lang::get('admin/assetdetails/message.update.error'));
}
My Route.php
Route::post('create', array('as' => 'savenew/assetdetail','uses' => 'Controllers\Admin\AssetdetailsController#postCreate'));
Route::get('{assetdetailId}/edit', array('as' => 'update/assetdetail', 'uses' => 'Controllers\Admin\AssetdetailsController#getEdit'));
Route::post('{assetdetailId}/edit', 'Controllers\Admin\AssetdetailsController#postEdit');
Now the problem is whenever i try to update my form my asset_number field throws an Error: The asset_number has already been taken.How do i pass the id in my controller while updating my form so that it throws error only if an already existing asset_number is used and not while editing the form with current asset_number.
I tried the following with no luck
Model
'asset_number' => 'mobileNumber' => 'required|min:5|numeric|unique:asset_details,asset_number,' . $id
Controller
Assetdetail::$rules['mobileNumber'] = 'required|min:5|numeric|unique:asset_details,asset_number,' . $id

Hi i finally found a working solution myself here is what i did please take a look
Controller
class AssetdetailsController extends AdminController
{
protected $validationRules = array
(
'asset_number' => 'required|alpha_dash|min:2|max:12|unique:asset_details,asset_number',
'asset_name' => 'alpha_space',
'asset_type_id' => 'required',
'shift' => 'required',
);
public function postCreate()
{
$validator = Validator::make(Input::all(), $this->validationRules);
// If validation fails, we'll exit the operation now.
if ($validator->fails())
{
// Ooops.. something went wrong
return Redirect::back()->withInput()->withErrors($validator);
}
// attempt validation
else
{
$assetdetail ->asset_number = e(Input::get('asset_number'));
$assetdetail ->asset_name = e(Input::get('asset_name'));
$assetdetail ->asset_type_id = e(Input::get('asset_type_id'));
$assetdetail ->shift = e(Input::get('shift'));
// Was the asset created?
if($assetdetail ->save())
{
// Redirect to the new location page
return Redirect::to("admin/settings/assetdetails")->with('success', Lang::get('admin/assetdetails/message.create.success'));
}
}
// Redirect to the location create page
return Redirect::to('admin/settings/assetdetails/create')->with('error', Lang::get('admin/assetdetails/message.create.error'));
}
public function postEdit($assetdetailId = null)
{
// Check if the location exists
if (is_null($assetdetail = Assetdetail::find($assetdetailId)))
{
// Redirect to the blogs management page
return Redirect::to('admin/settings/assetdetails')->with('error', Lang::get('admin/assetdetails/message.assetdetail_not_exist'));
}
$this->validationRules['asset_number'] = "required|alpha_dash|min:2|max:12|unique:asset_details,asset_number,{$assetdetail->asset_number},asset_number";
$validator = Validator::make(Input::all(), $this->validationRules);
// If validation fails, we'll exit the operation now.
if ($validator->fails())
{
// Ooops.. something went wrong
return Redirect::back()->withInput()->withErrors($validator);
}
else
{
$assetdetail ->asset_number = e(Input::get('asset_number'));
$assetdetail ->asset_name = e(Input::get('asset_name'));
$assetdetail ->asset_type_id = e(Input::get('asset_type_id'));
$assetdetail ->shift = e(Input::get('shift'));
if($assetdetail->save())
{
// Redirect to the saved location page
return Redirect::to("admin/settings/assetdetails/$assetdetailId/edit")->with('success', Lang::get('admin/assetdetails/message.update.success'));
}
}
// Redirect to the asset management page with error
return Redirect::to("admin/settings/assetdetails/$assetdetailId/edit")->with('error', Lang::get('admin/assetdetails/message.update.error'));
}
