Thirdly, it’s extremely easy to specify how the relationship When joining with the Dispute model under a specific condition. The problem with that approach would be that the PaymentĬlass would have wrong instruction that does not work except Itself would be just flat out wrong even though it would work. Secondly, adding a relationship to the Payment class

Had so little code change into Laravel’s core which made itĮasier for Taylor to take on the maintenance burden of suchįor it.
The pull request that added this functionality ConclusionĪ few nice things came into play while I was working on thisĮarlier today. Laravel interpret it as if there was a relationship between That relationship will work because the JoinĬlause brings the team_id field into the resultset, making Through the resolveRelationUsing method and will run the It will then give itĪnother chance by looking at the relations added via runtime Try to resolve the teams eager load relationship in the Now when the execution of the Builder takes place, Eloquent will Complex operations - > tap ( new TeamRelationship ) - > paginate ( ) class TeamRelationship To define a relationship during runtime without having toĪctually change the Model class. Makes a great addition to Query Builder’s abilities.
But that would be a completely fakeĪnd broken relationship for any case where the join is not Relationship to the Payment model that would link it to the Knowing all of this, I knew that I could, in theory, add a new The performance degradation of such with()Ĭlause would be a relevant negative impact on the report. That would completely ignore the JOIN that has been used for Mean changing the snippet to use with('disputes.teams'), however It to start from the Dispute was not an option as it wouldĪnother possibility would be to use HasOneThrough.
On the Payment model and not on the Dispute model. The obvious problem for me was the fact that the report starts Complex operations - > with ( 'teams:id,name' ) - > paginate ( ) The desired behavior was to add something along the following That dispute, relating it to a teams table. Request was to add the name of the support team responsible for A payment can only have oneĭispute and a dispute only relates to one payment. A disputes table refers toĭisputes opened relating payments.

Sake of oversimplifying it I came up with a similar use-case thatĬould illustrate the scenario: Imagine a payments table full ofĮntries related to payment records. Today I had to change an existing report to add a new field. It’s Query Builder provides OOP syntax for building complex Hit a database, a practice viewed as bad by some developers, and It empowers automation tests that actually Users use an intuitive and overly simplified Different mappings, different dimensions,ĭifferent focus point. One customer’s data is completely different Reports for them based on data that I have no idea what it is or That’s because after customers upload their data, I build Most of themĪre either over-the-moon expensive for my use case or they justĭon’t fit. There to help you run analytics on your business. I attribute a large portion of it to something I’ve been calling Thing about the reports I write is that they’re awfully dynamic. A big part of my work involves writing effective report.
