| 21:06:22 |  Georg Semmler (Gitter) | The filter only applies to folders right? |
| 21:06:28 |  Luuk Wester (Gitter) | Yes |
| 21:07:59 | Georg Semmler (Gitter) | In that case you could do something like the following: if is_request_metadata { |
| 21:08:13 | Georg Semmler (Gitter) | (edited) ... } => ... } ``` |
| 21:09:20 | Luuk Wester (Gitter) | That is a good idea! |
| 21:09:25 | Luuk Wester (Gitter) | Thanks for your help |
| 21:09:37 | Luuk Wester (Gitter) | I really should take the deep dive into diesel a bit more |
| 21:12:11 | Georg Semmler (Gitter) | No worries, asking questions here is totally fine (That's the place for asking questions about diesel :wink:) (I just happen to have "some" experience to make stuff with diesel work :wink:) |
| 21:12:52 | Georg Semmler (Gitter) | So if you hit another problem feel free to ask again. |
| 21:23:30 | Luuk Wester (Gitter) | Hahaha, I hope to get there one day! |
| 21:23:31 | Luuk Wester (Gitter) | Thanks |
| 21:25:15 | Georg Semmler (Gitter) | To do a bit of self promotion: I've done a workshop on diesel at the last rustfest in barcelona. The slides are available here. I think the have at least some information about what's possible and how things works internally. |
| 21:35:59 | Luuk Wester (Gitter) | Ah nice! |
| 21:36:07 | Luuk Wester (Gitter) | Ill read this |
| 21:36:33 | Luuk Wester (Gitter) | Provided custom derive, mapping is done by order, not by name |
| 21:37:02 | Luuk Wester (Gitter) | What is the reason for this decision? |
| 21:38:06 | Georg Semmler (Gitter) | a) It's faster b) Not every field returned by the database has a name c) We do not have any access to the field names there anyway |
| 21:38:48 | Georg Semmler (Gitter) | (In practice you will likely get a compiler error if you mix up the field order anyway) |
| 21:39:16 | Luuk Wester (Gitter) | Ah okay! |
| 21:40:00 | Luuk Wester (Gitter) | So if I have a table with four columns and a struct with two fields, that happen to be the two last ones, I need to write .select when using that struct? |
| 21:40:22 | Georg Semmler (Gitter) | Yes |

| 08:54:56 |  Said Aspen (Gitter) joined the room. | |
| 08:54:57 | Said Aspen (Gitter) | Hi everyone. New to Diesel and new to Rust. I have a table with uuid as PK and trying to use find on it, however getting this error ^^^^^ the trait diesel::Queryable<diesel::sql_types::Uuid, diesel::pg::Pg> is not implemented for &uuid::Uuid - Anyone have any clue as to why? Is it not possible to query using uuids as PKs? |
| 08:55:50 | Georg Semmler (Gitter) | Have you enabled the uuid or the uuidv07 feature for in your cargo.toml for diesel? Do you use a matching uuid version? |
| 09:02:03 | Said Aspen (Gitter) | uuid is enabled for diesel. I am using uuid v4. Not sure they match |
| 09:02:19 | Georg Semmler (Gitter) | Which uuid version do you use? |
| 09:02:33 | Georg Semmler (Gitter) | If you use another version as diesel it will not work. |
| 09:02:40 | Said Aspen (Gitter) | uuid = { version = "0.6", features = ["serde", "v4"] } |
| 09:06:21 | Georg Semmler (Gitter) | That should work fine Can you provide the corresponding code? |
| 09:06:48 | Said Aspen (Gitter) | Sure. Ill set it up, one second, thanks |
