QUESTION
I had a project that was using the latest version of Prisma (3.9.1) and was planning to place a CMS on top of it. Keystone seemed like a very good fit as they already use Prisma internally. Unfortunately I couldn't modify the Prisma schema because it was auto-generated from the Keystone schema. Is there a way to reverse the process and get a Keystone schema from Prisma ?
...ANSWER
Answered 2022-Feb-24 at 05:12At the moment there's no way to generate a Keystone schema from an existing Prisma schema. You'd need to create the Keystone schema manually so Keystone could generate a new Prisma schema file.
There's also currently no way to modify the Prisma schema generated by Keystone, though there's been talk of opening this up.

QUESTION
Good Day. Am a beginner in flutter and here's what am trying to achieve.
Am creating a form where users can edit payout account details. Account Name is a text field, Account Number is a Text Field, i want Bank Name to be a drop down because i'm using bulk payment system, so the bank name would need to match the slug or else it'll show invalid on my payment merchant.
Here's the code for the form if all fields are just text fields..

QUESTION
I have a large table, say ~1 million rows. At runtime, I need to perform an analysis of this table given some parameters. The analysis performs several queries, some related, some not.
Given the table
...ANSWER
Answered 2021-Dec-02 at 00:35You might be thinking of this the wrong way. Speaking to your specific concerns...
4 separate round trips to the database
Yes, that's true but ideally these would be happening simultaneously. Ie. you shouldn't be waiting for query 1 to return before you fire off query 2. Running the queries in parallel effectively makes the round-trip latency a constant.
How you achieve this comes down to the platform/language your app (the thing issuing these queries) is built in. You many need to reach for some async/await or threading tooling.
4 separate queries that must be made from scratch. The results of some queries should be able to be reused for others. Query 3 < Query 2 < Query 1, and Query 4 < Query 2. That is, the rows of query 2 are a subset of the rows of query 1. So having to go through all the rows again seems bad to me.
It's tempting to think this when you see multiple queries with similar conditions. The (sometimes counter-intuitive) fact is, database are pretty good at resolving queries against a well indexed table and, generally, the simpler the query, the easier it is for the query planner to build a query that will resolve quickly. Trying to be clever by building more complex queries can sometime backfire.
For example, pulling all the records where "championId" = 1
out then performing multiple queries against it might seem like a good idea but, in reality this may require the DB to copy a huge amount of data to memory. Plus, this temporary dataset may not be indexed the same way the original table was, meaning the subsequent queries, although they're running against a smaller dataset, may still be slower.
There definitely are times when isolating a small set of expensive data then querying it multiple ways is the right solution but the example you've given isn't one of them. Put another way, you might be overthinking it. Postgres is a powerful and mature platform that's entire job is consuming queries. Simple comparisons that hit indexed columns will generally be surprisingly fast.
(It all depends on your specifics though so if in doubt, benchmark it.)
Ok, But I Still WannaStill want to combine multiple queries together even though it's probably not necessary? Ok, let's try it..
A single query is always going to return a single record set. That is, you're always going to get back a "rectangular" set of data, where each row has a value for each column (even if it's null
). As such, there's 2 was you can add additional data into a query: by adding more rows or by adding more columns.
First lets setup some test data:
QUESTION
ANSWER
Answered 2021-Nov-30 at 01:31When selecting related items in Keystone, the Admin UI uses item labels – a human readable identifier assigned to each item.
The value used for the item label is controlled using the ui.labelField
list config:
ui.labelField
: Selects the field which will be used as the label column in the Admin UI. By default looks for a field called 'label', then falls back to 'name', then 'title', and finally 'id', which is guaranteed to exist.
In your example, you've configured Keystone to use the firstName
field as the label, which works ok, but presents the problem you've identified.
What we really need is 3rd field that combines both the first and last names together.
Now, we could do this with hooks, by combining the values and saving them to another text
field for example.
But this would duplicate the data and we'd need to remember to keep the values in sync, adding complexity.
Better to just concatenate these values when they're being read out of the DB.
For this, we can use virtual fields.
In the example given, the virtual field solution looks like this:
