我在使用查询生成器对2个表进行编辑和更新时遇到问题。 --->我按下提交按钮后---->数据插入新行---->不更新当前数据。
这是我的功能编辑(仅用于查看旧数据)
public function edit(Request $request, $id){
$tax_rate = TaxRate::find($id);
$tax_rate_details = TaxRateDetail::where('tax_rate_id', $id)->get();
$country = Country::all();
$geo_zones = GeoZone::all();
//dd($tax_rate);
//dd($tax_rate_details);
//dd($geo_zones);
if(!$tax_rate) {
return redirect('/');
}
return view('tax_management.edit',['country' => $country , 'tax_rate'=>$tax_rate , 'geo_zones'=>$geo_zones, 'tax_rate_details'=>$tax_rate_details]);
}
这是我的更新(我进行验证,而saveTax是保存的一部分)
public function update(Request $request, $id){
$this->validate($request,[
'country_id'=> 'required',
'tax_type' => 'required',
'name' => 'required|max:100',
'code' => 'required|max:50'
]);
//dd($request->input());
DB::beginTransaction();
try{
$tax_rate = TaxRate::find($id);
$tax_rate_details = TaxRateDetail::where('tax_rate_id', $id)->get();
$this->saveTax($request, $tax_rate);
DB::commit();
return redirect()->route('tax_management.index');
} catch (\Exception $ex){
//dd($ex);
DB::rollback();
return back()->withInput()->withErrors('Fail to save');
}
}
这是我的功能save()
private function saveTax(Request $request, $tax_rate){
$tax_rate->country_id = $request->input('country_id');
$tax_rate->geo_zone_id = $request->input('geo_zone_id');
$tax_rate->tax_type = $request->input('tax_type');
$tax_rate->name = $request->input('name');
$tax_rate->code = $request->input('code');
$tax_rate->description = $request->input('description');
if(!empty($request->input('active'))){
$tax_rate->active =1;
} else {
$tax_rate->active =0;
}
$tax_rate->save();
if($tax_rate->tax_rate_id) {
TaxRateDetail::where('tax_rate_id', $tax_rate->tax_rate_id)->delete();
}
if($request->input('tax_rate_details')){
foreach ($request->input('tax_rate_details') as $key => $value) {
$tax_rate_detail = new TaxRateDetail();
$tax_rate_detail->tax_rate_id = $tax_rate->tax_rate_id;
$tax_rate_detail->priority = $value['priority'];
$tax_rate_detail->date_from = $value['date_from'];
$tax_rate_detail->date_to = $value['date_to'];
$tax_rate_detail->rate = $value['rate'];
$tax_rate_detail->type = $value['type'];
$tax_rate_detail->active = $value['active'];
//dd($tax_rate_detail);
$tax_rate_detail->save();
}
}
}
我想用old(id)保存编辑更新。不创建新的。请帮忙谢谢。我不知道代码哪里出了问题。
