SQLSTATE [23000]：违反完整性约束：1048 列 'times' 不能为空

Question

我收到错误 SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'times' cannot be null (SQL: insert into sa_schedule (cinema_id, movie_id, times) 值 (-, [], ))

这是我的表格

<div class="form-group">
  <label>Cinema Name</label>
  <div>
    <input type="text" id="cinemaname">
  </div>
</div>
<div>
  <label>Movie Title</label>
  <div>
    <input type="text" id="movietitle">
  </div>
</div>
<div>
  <label>Time Schedule</label>
  <div>
    <input type="text" id="timesched">
  </div>
</div>

这是我的控制器

public function addcinema(Request $request)
{  //some codes here

    $addcine = new Schedule();
    $addcine->times = $request->timesched;
   //some codes here
    $addcine->save();

    return view ('dashboard');
}

Answer 1

change your form to look like this <div class="form-group">
  <label>Cinema Name</label>
  <div>
    <input type="text" name="cinemaname">
  </div>
</div>
<div>
  <label>Movie Title</label>
  <div>
    <input type="text" name="movietitle">
  </div>
</div>
<div>
  <label>Time Schedule</label>
  <div>
    <input type="text" name="timesched">
  </div>
</div>

Answer 2

只需将 times 列设为可为空即可。此外，您可以为其定义默认值。使用迁移，直接修改 db 或 phpmyadmin。

Answer 3

times 列必须有一个值，除非您更新该列以允许为空。
