@teal schooner How can I copy data from my dev db to my prod db ?

Let me check the knowledge base for you. One moment! :books:

#

To copy data from your development database to your production database in Convex, you can use the export and import functionality. Here are the steps:

  1. Export data from your development database using the npx convex export command. This will create a single file that contains your entire database. You can find more information about this in the Convex documentation (https://docs.convex.dev/database/import-export/export).

  2. Import the exported data into your production database using the npx convex import --prod command. This command will import the data into your production database. More details can be found in the Convex documentation (https://docs.convex.dev/database/import-export/import).

Remember to switch to the "production" environment in your dashboard to see the imported data.

Please note that the npx convex import command supports a --prod flag, which allows you to import your tables into the production deployment.

Also, be aware that the CONVEX_URL variable controls which deployment your frontend accesses. You can find the production URL in your dashboard under project settings.

@teal schooner Is there a way to filter the data from an edge ?
I get users from an inquiry through an edge, but I want to get only the user from an organization using an edge to organizations
const users = inquiry.edge("users")

Let me check the knowledge base for you. One moment! :books:

#

Based on the knowledge sources provided, it's currently not supported to paginate or filter a many-to-many query directly on an edge in Convex. However, there are workarounds you can use.

One workaround is to add an organizationId field to your users table and then use the filter method to get only the users from a specific organization. Here's an example:

const users = await ctx.table("users").filter(q => q.eq(q.field("organizationId"), organizationId))

Another workaround suggested by the support staff is to create a "sentinel" group, to which you assign all the users who don't have a group. This way, you can use the paginate method on 1:many edges.

Remember to use an index for better performance when using the filter method.

@teal schooner Why can't I update the document from this query ?

const anwserInDb2 = await ctx.table("users").get(userId).edge("answers").filter((q) => q.eq(q.field("questionId"), questionId))

teal schoonerBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The query you're using is a read-only query. It's retrieving a filtered set of "answers" related to a specific user, but it doesn't provide a way to update those answers directly.

If you want to update an answer, you'll need to get a reference to the specific answer document first. Here's an example of how you might do that:

const answer = await ctx.table("answers").get(answerId);

Once you have a reference to the specific answer document, you can use the patch method to update it:

await answer.patch({ fieldToUpdate: newValue });

Remember to replace fieldToUpdate with the actual field you want to update and newValue with the new value for that field.

@teal schooner I got this error :

Type 'TableName' does not satisfy the constraint '"users"'.
Type 'string' is not assignable to type '"users"'.ts(2344)
(type parameter) TableName in type Ent<TableName extends string>

teal schoonerBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The error message you're seeing is a TypeScript type error. It's saying that the type 'TableName' does not satisfy the constraint '"users"', meaning that TypeScript is expecting a specific string value "users", but it's getting a more general string type instead.

This error typically occurs when you're trying to use a generic type parameter (in this case, 'TableName') in a place where a specific string literal type is expected.

Without seeing the exact context of your code, it's hard to provide a specific solution. However, you might want to check the following:

  • Make sure you're passing the correct table name when calling a function or method that expects a specific table name.
  • If 'TableName' is a variable, make sure it's assigned the value "users" before you use it in a context where "users" is expected.
  • If 'TableName' is a type parameter in a generic function or class, make sure you're using it correctly. You might need to constrain it to a specific set of string literal types, or replace it with a specific string literal type if it's not meant to be generic.

@teal schooner How is constructed the url of a convex api call ?

teal schoonerBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The URL of a Convex API call is constructed by appending the specific API endpoint to your Convex backend deployment URL.

Here's an example of how it's done:

  1. First, you need to find your backend deployment URL. This can be found on your dashboard settings page.

  2. Then, append the specific API endpoint to this URL. For example, if you're calling the /api/query endpoint, the API URL will be <CONVEX_URL>/api/query.

Here's an example of a full API URL:

<https://acoustic-panther-728.convex.cloud/api/query>

In this example, <https://acoustic-panther-728.convex.cloud> is the Convex backend deployment URL, and /api/query is the API endpoint.

You can then use this URL to make HTTP requests to the Convex API. For example, you can use the curl command to make a POST request to this URL:

curl <https://acoustic-panther-728.convex.cloud/api/query> -d '{"path": "messages:list", "args": {}, "format": "json"}' -X POST -H "Content-Type: application/json"

In this command, -d specifies the data to send in the request, -X POST specifies the HTTP method to use, and -H "Content-Type: application/json" specifies the content type of the request.

@teal schooner And I call the fetchMutation(api.users.create, {}) ?

teal schoonerBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The fetchMutation function is used to call a mutation in Convex. The first argument is the mutation you want to call, and the second argument is an object containing the arguments for the mutation.

In your case, api.users.create is the mutation you're calling, and {} is the arguments object. Since you're passing an empty object, this means you're calling the mutation without any arguments.

Here's an example of how you might use fetchMutation:

const user = await fetchMutation(api.users.create, {
  name: 'John Doe',
  email: '[email protected]',
});

In this example, api.users.create is the mutation, and { name: 'John Doe', email: '[email protected]' } is the arguments object. This will create a new user with the name 'John Doe' and the email '[email protected]'.

Please note that the actual arguments you need to pass will depend on the specific mutation you're calling. You should check the definition of the api.users.create mutation to see what arguments it expects.

@teal schooner What is the url called for this api call: fetchMutation(api.users.create, {}) ?

teal schoonerBOT
#

Let me check the knowledge base for you. One moment! :books:

#

The fetchMutation function from Convex's Next.js module is used to execute a Convex mutation function. It abstracts the details of constructing the URL and making the HTTP request.

When you call fetchMutation(api.users.create, {}), it makes a POST request to the /api/mutation endpoint of your Convex backend. The exact URL would depend on your Convex backend deployment URL, but it would look something like this:

<https://your-convex-backend-url/api/mutation>

The api.users.create argument is used to specify the mutation function to run, and {} is the arguments object for the mutation.

Please note that the actual network request is handled by the fetchMutation function, so you don't need to construct the URL or make the HTTP request yourself.

@teal schooner how would I make this call fetchMutation(api.users.create, {}) using mock service worker ?

teal schoonerBOT
#

Let me check the knowledge base for you. One moment! :books:

#

To use Mock Service Worker (MSW) with Convex's fetchMutation function, you would need to set up a mock server that intercepts the network requests made by fetchMutation and returns mock responses. Here's a basic example of how you might do this:

First, install MSW in your project:

npm install msw --save-dev

Then, set up the mock server:

// mockServer.js
import { setupServer } from 'msw';
import { rest } from 'msw';

const server = setupServer(
  rest.post('<https://your-convex-backend-url/api/mutation',> (req, res, ctx) => {
    // Check if the request is for the api.users.create mutation
    if (req.body.path === 'users:create') {
      // Return a mock response
      return res(
        ctx.json({
          data: {
            // Mock user data
            id: '1',
            name: 'John Doe',
            email: '[email protected]',
          },
        })
      );
    }
  })
);

export { server };

In your test file, use the mock server:

// test.js
import { server } from './mockServer.js';
import { fetchMutation, api } from 'convex';

beforeAll(() => server.listen());
afterEach(() => server.resetHandlers());
afterAll(() => server.close());

test('creates a user', async () => {
  const user = await fetchMutation(api.users.create, {});
  expect(user).toEqual({
    id: '1',
    name: 'John Doe',
    email: '[email protected]',
  });
});

In this example, the mock server intercepts POST requests to <https://your-convex-backend-url/api/mutation> and checks if the request is for the users:create mutation. If it is, it returns a mock user object.

Please replace '<https://your-convex-backend-url/api/mutation'> with your actual Convex backend URL.
