问题 I have existing data in a mysql db whose columns are camelCased. I can't change them to snake case. For instance: when I try to use "jobRole", I get "job_role". I want it to be "jobRole". Is there a setting in laravel to support this? I've read about mutators but don't understand them. Is that the solution? If so, how do I do this? 回答1: Discovered you can do this. In the model, redefine "snakeAttributes" to "false" like this: class YourModel extends Eloquent{ public static $snakeAttributes =

问题 I now know that I can create a User using the haveMany relationship between a Region and User by doing this: $region = Region::find($data['region_id']); $region->users()->create([ 'username' => $data['username'], 'email' => $data['email'], 'first_name' => $data['first_name'], 'last_name' => $data['last_name'], 'password' => bcrypt($data['password']), ]); But what if there are multiple foreign keys, how do you create a user without making them fillable for more than 1 foreign key constraint?

问题 I have a table like this: table - field1: tinyint - field2: varchar (nullable) - datefield: timestamp (nullable) Now I want to get all entries where field1 is 1, field2 is null and where datefield is smaller than X or null. I already tried something like this: $query = Model::where('field1', 1) ->whereNull('field2') ->where('datefield', '<', $date) ->orWhereNull('datefield'); but thats not working. I always get every entry where datefield is null. It doesn't matter what the other fields are.

问题 I have two rounds "first and knock-out". Only 4 teams can go to knock-out round, those who got the highest point on the first round. Now firstly, I want to select that 4 teams from first round and then check whether the inputted team is on the selected 4 teams or not. Take a look to my code(So far I tried). My problem is, if I input two team names from below dd($kos) it will save the $matches->round="first"Here I attach a dd($kos),if my inputted data is in the dd($kos) only then the $matches
