QUESTION
Let's say I have two objects: Product and Seller
Products can have multiple Sellers. A single Seller can sell multiple Products.
The goal is to write a seeding script that successfully seeds my MongoDB database such that Keystone.js's CMS recognizes the many-to-many relationship.
SchemasProduct.ts
ANSWER
Answered 2021-May-01 at 14:16I figured out a solution. Here's the background:
When I define the schema, Keystone creates corresponding MongoDB collections. If there is a many-to-many relationship between object A and object B, Keystone will create 3 collections: A, B, and A_relationshipToB_B_relationshipToA.
That 3rd collection is the interface between the two. It's just a collection with pairs of ids from A and B.
Hence, in order to seed my database with a many-to-many relationship that shows up in the Keystone CMS, I have to seed not only A and B, but also the 3rd collection: A_relationshipToB_B_relationshipToA.
Hence, seed-data/index.ts
will have some code that inserts into that table:

I am using Keystone.js to manage a PostgreSQL database. My database has two separate tables (Customer

...ANSWER
Answered 2020-Sep-26 at 03:46No primary keys of joined tables do not have the same because you typically DO NOT JOIN primary key to primary key. You join an attribute column in the child table (usually defined as a Foreign Key) to the PK of the parent. Those are the columns that must be of the same type. Your are looking for definitions something like:

QUESTION
I have built my app which runs fine locally. When I try to run it in docker (docker-compose up) it appears to start, but then throws an error message:
...ANSWER
Answered 2018-Sep-13 at 12:56It is not working properly because you are sending the wrong host.
your container does not understand what is localhost:27017
since it's your computer address and not its container address.
Important to understand that each service has it's own container with a different IP. The beauty of the docker-compose that you do not need to know your container address! enough to know your service name:
QUESTION
My Keystone.js 4 project using Node 10.15 is failing to start on Heroku:
...ANSWER
Answered 2019-Feb-22 at 01:58So it seems the problem is due to npm 6.5.x not installing all of Keystone's dependencies. Switching to Yarn as the package manager fixes this.
- I installed the latest version of Yarn, 1.13.0 as of now.
- Installed dependencies via
yarn
- Committed the yarn.lock file
- Specified
"yarn": "1.13.0"
in the "engines" section of my package.json and removed "npm" from the engines. - Re-deployed to Heroku and it works as expected.
Hope this helps someone!
QUESTION
I have a KeystoneJS app on a Google Compute Engine instance, after executing mongod and npm start in my project folder, I run gcloud app deploy and get the following error:
...ANSWER
Answered 2019-Jan-12 at 10:05It seems that while deploying to GAE, you're keeping the default connection to a local hosted mongo database. (failed to connect to server [localhost:27017]
)
Since GAE environment doesn't have mongodb running, you have to create a mongo database (there are many different mongodb services that you could use here) and set your project up with MONGO_URI
env variable.
Keystonejs will then try to connect the database you set in this variable.
I hope this comment will help you, if you still have some issues setting all that stuff up, you can show us your app.yaml file ;)
QUESTION
I integrated projects on other platforms with Sentry before and it is quite simple. But at this time, I'm using KeystoneJs, which is created on the top of Express.
Sentry offers this tutorial to let Express users integrate their applications with Sentry: https://sentry.io/for/express/
But it is not clear to me how to apply it on a KeystoneJs project, since we can't just invoke keystone.use()
I know we have some hooks available on keystone, so I also tried this:
...ANSWER
Answered 2018-Oct-26 at 19:39Answering my own question. No need to add a new express app for this. All I had to do was use keystone.set()
instead of app.use()
.
Only note: When working directly with Express, you can add several error handling middlewares while with keystone, I already had something like keystone.set('500', myCustomErrorHandlingMiddleware);
So I moved the code to use sentry.Handlers.errorHandler()
to inside of it.
QUESTION
Oh god why is this so hard. I've now spent 3 days trying to get this seemingly simple crap to work.
I need it to: - npm install on CI server (works) - run tests (works) - build angular frontend (works) - ship code to server via rsync (works) - ssh into server (works) - - and npm install (doesn't work. dies because of npm warnings, I think) - - restart pm2 process (doesn't work as there's no elegant way to say start or restart)
At the deploy step, I have this script in the codeship UI

Answered 2018-Oct-01 at 21:37I have tried to use the half-baked debug tool, but it magically asks me for a password when I try to login in... Eh?
I'd say this was a correct instinct. There are too many possible scenarios for why you're coming across these unintended behaviors and nothing short of running the build live with a ssh debug session will likely get to the bottom of that.
Please see our documentation section for troubleshooting password prompts for ssh debug sessions.
If an ssh debug session doesn't solve your situation, then please reach out to us at support@codeship.com with your build url and we'll take a closer look.

...ANSWER
Answered 2018-Jun-29 at 12:23For clarification: you are trying make the entry in the Mongo database be the full path to the image not just the name of the image?
If I need something appended to the filename I do it on the template side, I guess you don't want to do that? Maybe if you explain the use case a little more?
