由 我们两清 提交于 2019-12-12 03:29:20
问题 Let's consider the image above. I would like to show duplicated entries as one entry and also I want to show the sum of the " stock " column. In this case it should be 5722. Is it possible to do it using Eloquent? Or what are the best ways to do it? 回答1: Not sure how your database / query is built but you could maybe use something like that: Item::groupBy('item_name') ->selectRaw('*, sum(stock) as sum') ->get(); It will return a collection of Item with an additional “ sum ” field 回答2: This

Get path to file in storage

由 只谈情不闲聊 提交于 2019-12-12 01:48:48
问题 I saved a file to storage using: $request->file('avatar')->store('avatars'); Which saved it to: storage/app/avatars/avatar.png How can I get the path to this file/folder ( not the URL)? What is the correct way to do this using Laravel's Filesystem? 回答1: There is no correct way to do this; because it should not be done. The Storage is an opaque system to talk to different storage systems; as such there is no api to get the backing file path. As an example, that wouldn't work with Amazon S3.

How do I make a referral program in Laravel?

由 你。 提交于 2019-12-12 01:37:53
问题 I am trying to create a program where other users can sign up using links of other already registered users.

There is a hidden input value which would contain the value of ref_id if it exists. My database has a column called referred_by which is an INT and set to null by default. When someone registers using the link with ref_id,

withCount() doesn't include deleted rows?

由 谁说胖子不能爱 提交于 2019-12-11 16:47:17
问题 How can I make withCount('comments') also include all deleted/trashed rows? For example, if I have 5 comments, and I delete 1, I still expect withCount('comments') to return 5, but instead it's returning 4. My full query looks something like this: $query = Post::withTrashed() ->withCount('comments') ->get(); 回答1: You can use the withTrashed method: >withTrashed() 回答2: I think you can try this $query = Post::withCount('comments') ->withTrashed() ->get(); OR $query = DB::table('post') ->select(
