Schema hasn't been registered for model...

Hello, I have been trying to add new schemes to my models folder for my MongoDB database and for some reason the newly added models arent being registered by Nuxt. I have tried using the Schemes in API (creating documents and querying the collection) and it works all fine. But until I try populating other models referring to the new ones, it show that the scheme hasnt been registered. Interesting is that it most of the time doesnt, but sometimes it does and I got no idea what the problem could be. Any help would be appreciated and thanks in advance 😄 (For context about the attached images, Category is the newly added scheme. I also have a new Article scheme which is linked to a user, and that also has the same problem.)

Hi @Michal Winter. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can offer some insights and suggestions regarding your issue with Nuxt and MongoDB schemas. It seems you're using the nuxt-mongoose module to integrate MongoDB with your Nuxt application. The problem you're experiencing with schemas not being registered consistently could be related to how the models are defined and imported. Here are some steps you can try to resolve the issue: 1. Make sure your schema files are in the correct location. By default, the nuxt-mongoose module looks for models in the models directory. Check your nuxt.config.ts file to ensure the modelsDir option is set correctly:

export default defineNuxtConfig({
  // ... other config
  mongoose: {
    uri: process.env.MONGODB_URI,
    options: {},
    modelsDir: 'models'
  }
})

export default defineNuxtConfig({
  // ... other config
  mongoose: {
    uri: process.env.MONGODB_URI,
    options: {},
    modelsDir: 'models'
  }
})

2. Ensure that your schema files are using the correct import and export syntax. Here's an example of how your schema file should look:

// server/models/category.schema.js
import { defineMongooseModel } from "#nuxt/mongoose"

export const CategorySchema = defineMongooseModel({
  name: 'CategorySchema',
  schema: {
    // Your schema definition here
  }
})

// server/models/category.schema.js
import { defineMongooseModel } from "#nuxt/mongoose"

export const CategorySchema = defineMongooseModel({
  name: 'CategorySchema',
  schema: {
    // Your schema definition here
  }
})

3. If you're still experiencing issues, try moving your API logic that uses these models into the server directory. According to the Stack Overflow answer (https://stackoverflow.com/questions/76986927), files in the server directory are only accessible within the server folder, except for API routes. 4. If the problem persists, it might be worth creating a minimal reproduction of the issue and seeking help from the Nuxt community. You can use the Nuxt StackBlitz playground (https://stackblitz.com/edit/nuxt-starter-pkwfkx?file=pages%2Findex.vue) to create a reproduction. 5. If you're unable to resolve the issue, consider reporting it as a potential bug (https://nuxt.com/docs/community/reporting-bugs) to the Nuxt team. Make sure to include a minimal reproduction and all relevant details about your setup. Remember, when working with Nuxt and server-side features like MongoDB integration, it's important to ensure that your code is structured correctly for server-side execution. If you continue to face issues, don't hesitate to seek further help from the Nuxt community through their official channels (https://nuxt.com/docs/community/getting-help). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

No damn clue.. Tried moving the models folder into the root of the project and no change @kapa.ai Looks like only for the "populate" it doesnt work.

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on your additional information, it seems the issue is specifically related to the "populate" operation not working correctly with your newly added schemas. Unfortunately, the knowledge sources provided don't contain specific information about this particular problem with populating models in Nuxt and MongoDB. However, I can offer some general suggestions based on common issues with MongoDB population: 1. Ensure that the field you're trying to populate is defined as a reference in your schema. For example:

import { defineMongooseModel } from "#nuxt/mongoose"

export const ArticleSchema = defineMongooseModel({
  name: 'ArticleSchema',
  schema: {
    // ... other fields
    category: {
      type: 'ObjectId',
      ref: 'CategorySchema'
    }
  }
})

import { defineMongooseModel } from "#nuxt/mongoose"

export const ArticleSchema = defineMongooseModel({
  name: 'ArticleSchema',
  schema: {
    // ... other fields
    category: {
      type: 'ObjectId',
      ref: 'CategorySchema'
    }
  }
})

2. Make sure that the model name you're using in the ref field exactly matches the name you've given to the schema when defining it. 3. Double-check that you're using the correct syntax for population in your query. For example:

const article = await ArticleSchema.findById(id).populate('category')

const article = await ArticleSchema.findById(id).populate('category')

4. If you're using the population in an API route, ensure that it's placed in the correct location within your Nuxt project structure, typically in the server/api directory. If you continue to face issues specifically with population while other operations work fine, it might be worth creating a minimal reproduction of the problem and seeking help from the Nuxt community. You can use the Nuxt StackBlitz playground (https://stackblitz.com/edit/nuxt-starter-pkwfkx?file=pages%2Findex.vue) to create a reproduction, as mentioned in the Nuxt documentation on reporting bugs (https://nuxt.com/docs/community/reporting-bugs). If you need more specific help, please provide more details about your schema definitions, the exact populate query you're using, and any error messages you're receiving. This will help in diagnosing the issue more accurately. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Really looks like a bug.. When I manually fill the category value, using a CategoryScheme query, it works like a charm.

yeah, seen that too You have to reference the schemas somwhere otherwise they'll be shaken out
