问题 I have an array of JSON objects within my database (as depicted by the image below) How do I search for a specific value within it? Say I want the record where the "ends_at" field is equal to "2018-11-24 08:00:00" I've tried using ->where('column->starts_at', '2018-11-24 08:00:00') or even tried ->whereJsonContains('column->starts_at', '2018-11-24 08:00:00'). Within the model I've cast the column to an array - am I missing something, or can this not be done? 回答1: Use this: ->whereJsonContains

问题 I have 3 tables: posts , tags , post_tag . Each Post has many tags so I use hasMany method for them. But when I choose for example 3 tags in my dropdown list, I can't add them to post_tag and as the result I can't select and show each post's tags. My Post model: class Post extends Eloquent{ public function tag() { return $this->hasMany('Tag'); } } My Tag model: class Tag extends Eloquent{ public function post() { return $this->belongsToMany('Post'); } } And my postController : class
