Laravel: update function creating new record instead of updating existing one - ajax

Question

Hi guys i am trying to update my existing record in my edit page..so when i clicked on update button it is creating new record instead of updating existing one
Here is my controller:
public function update(Request $request, Qtype_editor $qtype_editor)
{
$qtype_editor = new Qtype_editor();
$qtype_editor->qtype_name = $request->input('qtype_name');
$qtype_editor->qtype_subject_id = $request->input('qtype_subject_id');
$qtype_editor->qtype_topic_id = $request->input('qtype_topic_id');
$qtype_editor->qtype_option = $request->input('qtype_option');
$qtype_editor->qtype_json = $request->input('qtype_json');
$qtype_editor->sort_order = $request->input('sort_order');
$qtype_editor->save();
return redirect()->route('eqtype-editor.index');
}
And i have ajax call where i am updating records from ajax
Here is my ajax code
function saveEditQtypeFile(edit_qtype_id)
{
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
chk_EnumValuesValidation = chkEnumValuesValidation(isSoltion, stepCount);
if(!chk_EnumValuesValidation)
{
return false;
}
else
{
// Function to push "MainArray" in current Solution
pushVarMainArrayInThisSolution(isSoltion, var_main_arr.var_arr_values);
arr = ar;
var edit_qtype_id = $('#edit_qtype_id').val();
var qtype_name = $('#qtype_name').val();
var subject_list = $('#qtype_subject_id').val();
var ddl_topic_type = $('#qtype_topic_id').val();
var qtype_option = $('#qtype_option').val();
var jasondata = $('#qtype_json').val();
var sort_order = $('#sort_order').val();
var jasondata = $('#jasonData').val();
var sendInfo = {
'edit_qtype_id':edit_qtype_id,
'arr':arr,
'saveEditQtypeFile':1,
'qtype_name':qtype_name,
'qtype_subject_id':subject_list,
'qtype_topic_id':ddl_topic_type,
'qtype_option':qtype_option,
'qtype_json':jasondata,
'sort_order':sort_order
};
console.log(sendInfo);
//var loadQtypeInfo = JSON.stringify(sendInfo);
$.ajax({
url: "/eqtype-editor/update",
type: "POST",
data :sendInfo,
contentType: "application/x-www-form-urlencoded",
success: function(response)
{
alert('Your file is updated!');
},
error: function (request, status, error)
{
alert('problem with updating record!!!');
},
complete: function()
{}
});
}
}
Here is my route file:
Route::post('eqtype-editor/update', 'QtypeEditorController#update');
Can anyone help me where i did mistake..thanks in advance.

Answer 1

There are two ways to achieve update of records
One - minor change in your code to just get it working
public function update(Request $request, Qtype_editor $qtype_editor)
{
$qtype_editor = Qtype_editor::findOrFail($request->edit_qtype_id);
$qtype_editor->qtype_name = $request->input('qtype_name');
$qtype_editor->qtype_subject_id = $request->input('qtype_subject_id');
$qtype_editor->qtype_topic_id = $request->input('qtype_topic_id');
$qtype_editor->qtype_option = $request->input('qtype_option');
$qtype_editor->qtype_json = $request->input('qtype_json');
$qtype_editor->sort_order = $request->input('sort_order');
$qtype_editor->save();
return redirect()->route('eqtype-editor.index');
}
Second:
Following Laravel conventions - The Laravel Way
Route definition should be: PUT/PATCH methods for resource update
Route::match(
['PUT', "PATCH'],
'eqtype-editor/{qtype_editor}', //qtype_editor param for route model binding
'QtypeEditorController#update'
);
public function update(Request $request, Qtype_editor $qtype_editor)
{
//$qtype_editor will be resolved via route model binding
//object representing db record with id of $qtype_editor passed from frontend
//$qtype_editor = Qtype_editor::findOrFail($request->edit_qtype_id);
$qtype_editor->qtype_name = $request->input('qtype_name');
$qtype_editor->qtype_subject_id = $request->input('qtype_subject_id');
$qtype_editor->qtype_topic_id = $request->input('qtype_topic_id');
$qtype_editor->qtype_option = $request->input('qtype_option');
$qtype_editor->qtype_json = $request->input('qtype_json');
$qtype_editor->sort_order = $request->input('sort_order');
$qtype_editor->save();
return redirect()->route('eqtype-editor.index');
}
Javascript
$.ajax({
url: `/eqtype-editor/${edit_qtype_id}`, //add the id to the route
type: "PUT",
data :sendInfo,
contentType: "application/x-www-form-urlencoded",
success: function(response)
{
alert('Your file is updated!');
},
error: function (request, status, error)
{
alert('problem with updating record!!!');
},
complete: function()
{}
});
