php - 当两个表具有相同的列名时，连接关系表后对模型进行排序

Question

我正在 Laravel 上构建一个应用程序，其中有 Project 和 LatestStatus 模型，我有一个表，其中包含分拣设施。所以我可以按名称、最新状态、最后更新时间等进行排序。所以这个架构是:

projects
    id
    name -> string
    state -> string
    region -> string
    status -> enum ('saved', 'draft')
    created_at -> timestamp
    updated_at -> timestamp

project_latest_status
    id
    project_id -> integer   // (project id foreign key)
    status -> string       //  (current status of project)

我想通过加入 latest_status 表对项目进行排序，并根据项目的当前状态进行排序。为此我尝试了这样的事情:

Project::where('status', 'saved')
    ->when( $request->name , function( $q) use( $request ) {
        $q->where('name', 'like', '%' . $request->name .'%');
    }) 
    ->when($request->status, function ($q) use($request) {
        $q->whereHas('latestStatus', function ($q) use($request){
            $q->whereHas('status', function ($q) use($request) {
                $q->whereIn('name',  collect($request->status)->pluck('name') );
            });
        });
    })
    ->when($request->sort_by_column, function ($q) use($request) {
        $q->when($request->sort_by_column['column'] == 'name' || $request->sort_by_column['column'] == 'website', function ($q) use($request) {
            $q->orderBy($request->sort_by_column['column'], $request->sort_by_column['order'] );
        })
        ->when($request->sort_by_column['column'] == 'added_date' , function ($q) use ($request) {
            $q->orderBy('created_at', $request->sort_by_column['order']);
        })
        ->when($request->sort_by_column['column'] == 'status', function ($q) use ($request) {
            $q->join('project_latest_status', 'projects.id', '=', 'project_latest_status.project_id')
                ->join('project_status', 'project_latest_status.status', '=', 'project_status.id')
                ->select('projects.*', 'project_status.name as status_name')
                ->orderBy('status_name', $request->sort_by_column['order']);
        })
    })->get();

一切正常，但一旦我单击状态排序，就会出现错误:

SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'status' in where clause is ambiguous (SQL: select count(*) as aggregate from projects inner join project_latest_status on projects.id = project_latest_status.project_id inner join project_status on project_latest_status.status = project_status.id where status = saved and projects.deleted_at is null)"

帮我解决这个问题。谢谢

更改来源

where('status', 'saved')

至

where('projects.status', 'saved')

或者在任何地方将 status 与另一个连接表另一个相同的字段一起使用，因此您需要指定要按 status 过滤的表
