Hi @daw. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Refine, you can handle relational data in tables using the useMany hook. This hook allows you to fetch relational data according to your needs. Here is an example of how you can use the useMany hook to fetch categories for each post in a table:
import React from "react";
import { useTable, HttpError, useMany } from "@refinedev/core";

export const HomePage: React.FC = () => {
const { tableQueryResult } = useTable<IPost, HttpError>({
resource: "posts",
});
const posts = tableQueryResult?.data?.data ?? [];

const categoryIds = posts.map((item) => item.category.id);
const { data: categoriesData, isLoading } = useMany<ICategory>({
resource: "categories",
ids: categoryIds,
queryOptions: {
enabled: categoryIds.length > 0,
},
});

if (tableQueryResult?.isLoading) {
return <div>Loading...</div>;
}
// Rest of the component
};
import React from "react";
import { useTable, HttpError, useMany } from "@refinedev/core";

export const HomePage: React.FC = () => {
const { tableQueryResult } = useTable<IPost, HttpError>({
resource: "posts",
});
const posts = tableQueryResult?.data?.data ?? [];

const categoryIds = posts.map((item) => item.category.id);
const { data: categoriesData, isLoading } = useMany<ICategory>({
resource: "categories",
ids: categoryIds,
queryOptions: {
enabled: categoryIds.length > 0,
},
});

if (tableQueryResult?.isLoading) {
return <div>Loading...</div>;
}
// Rest of the component
};
In this example, useTable is used to fetch the posts data. Then, the useMany hook is used to fetch the categories of each post. The ids option in useMany is set to the array of category ids from the posts data. The queryOptions is set to enable the query only if there are category ids to fetch. For more information, you can refer to the Refine documentation on handling relational data (https://refine.dev/docs/guides-concepts/tables#relationships-). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can i do this with antd?
kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- In Refine, you can handle relational data in tables with Ant Design using the useTable hook. Here is an example of how you can do this:
import { List, Table, useTable, Select, FilterDropdown, FilterDropdownProps } from "@pankod/refine";
import { TagField } from "@pankod/refine";

export const PostList: React.FC = () => {
const { tableProps, isFetching } = useTable<IPost>();

if (isFetching) return "loading...";
return (
<List>
<Table {...tableProps}>
<Table.Column
dataIndex="category"
title="Category"
render={(value: string) => {
// Gets the title of the category from the data object, which is the result of the useMany hook.
return data?.data.find((p) => p.id === value)?.title;
}}
filterDropdown={(props: FilterDropdownProps) => (
<FilterDropdown {...props} mapValue={(selectedKeys) => selectedKeys.map((i) => parseInt(i.toString()))}>
<Select style={{ minWidth: 200 }} mode="multiple" {...selectProps} />
</FilterDropdown>
)}
/>
<Table.Column dataIndex="status" title="Status" render={(value: string) => <TagField value={value} />} />
</Table>
</List>
);
};
import { List, Table, useTable, Select, FilterDropdown, FilterDropdownProps } from "@pankod/refine";
import { TagField } from "@pankod/refine";

export const PostList: React.FC = () => {
const { tableProps, isFetching } = useTable<IPost>();

if (isFetching) return "loading...";
return (
<List>
<Table {...tableProps}>
<Table.Column
dataIndex="category"
title="Category"
render={(value: string) => {
// Gets the title of the category from the data object, which is the result of the useMany hook.
return data?.data.find((p) => p.id === value)?.title;
}}
filterDropdown={(props: FilterDropdownProps) => (
<FilterDropdown {...props} mapValue={(selectedKeys) => selectedKeys.map((i) => parseInt(i.toString()))}>
<Select style={{ minWidth: 200 }} mode="multiple" {...selectProps} />
</FilterDropdown>
)}
/>
<Table.Column dataIndex="status" title="Status" render={(value: string) => <TagField value={value} />} />
</Table>
</List>
);
};
In this example, the useTable hook is used to fetch the posts data and the isFetching state. The Table.Column component is used to render each column in the table. The render prop is used to display the title of the category for each post. The filterDropdown prop is used to create a dropdown filter for the category column. For more information, you can refer to the Refine documentation on handling relational data with Ant Design (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-table#how-can-i-handle-relational-data). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai im using vite no typescript
kapa.ai
kapa.ai3mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- Refine supports both Vite and JavaScript. Even though Refine is written in TypeScript and it is recommended to use TypeScript, you can also work with JavaScript without any problems. If you're using Vite, you can integrate it with Refine and Shadcn UI. Here are the major steps involved in integrating Shadcn with Refine using Vite: 1. Install TailwindCSS and dependencies. Including setting up TailwindCSS and PostCSS configurations. 2. Configure Vite to set up source path alias for Shadcn directories. 3. Initialize and configure Shadcn components.json file. Here's an example of how to install TailwindCSS and its dependencies:
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p
npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p
This generates tailwind.config.js and postcss.config.js files and places them at the root folder. You can also configure the source path for the import alias in Vite:
npm i -D @types/node
npm i -D @types/node
And then update the vite.config.js file:
import * as path from "path"
import react from "@vitejs/plugin-react"
import { defineConfig } from "vite"

export default defineConfig({
plugins: [react()],
resolve: {
alias: {
"@": path.resolve(__dirname, "./src"),
},
},
})
import * as path from "path"
import react from "@vitejs/plugin-react"
import { defineConfig } from "vite"

export default defineConfig({
plugins: [react()],
resolve: {
alias: {
"@": path.resolve(__dirname, "./src"),
},
},
})
For more information, you can refer to the Refine documentation on working with JavaScript (https://refine.dev/docs/guides-concepts/faq#can-i-work-with-javascript) and the Refine blog post on integrating Shadcn with Refine (https://refine.dev/blog/shadcn-ui#integrating-shadcn-with-refine). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai import { SearchOutlined } from "@ant-design/icons"; import { CreateButton, DeleteButton, EditButton, FilterDropdown, List, useTable, } from "@refinedev/antd"; import { getDefaultFilter, useGo, useMany } from "@refinedev/core"; import { Input, Space, Table } from "antd"; import { get } from "http"; import React from "react"; const WorklogList = () => { const go = useGo(); const { tableProps, filters } = useTable({ resource: "worklogs", onSearch: (values) => { return [ { field: "log_name", operator: "contains", value: values.log_name, }, ]; }, pagination: { pageSize: 12, }, sorters: { initial: [ { field: "created_at", order: "desc", }, ], }, filters: { initial: [ { field: "log_name", operator: "contains", value: undefined, }, ], }, }); const project_id = tableProps.dataSource?.map((p) => p.project_id.toString()) || []; console.log(project_id); const { data: projectData, isFetching } = useMany({ resource: "projects", ids: project_id, }); console.log(projectData); im getting error column projects.id does not exist
kapa.ai

Let me check the knowledge base for you. One moment! :books: ---------------------- The error message "column projects.id does not exist" suggests that the database table "projects" does not have a column named "id". In the provided code, you are using the useMany hook to fetch data from the "projects" resource based on an array of project_id. The useMany hook expects that the resource has a primary key column named "id".
const { data: projectData, isFetching } = useMany({
resource: "projects",
ids: project_id,
});
const { data: projectData, isFetching } = useMany({
resource: "projects",
ids: project_id,
});
If your "projects" table uses a different column name for the primary key, you need to adjust your code accordingly. For example, if your primary key column is named "project_id", you should change the ids prop in the useMany hook to match this. If the "projects" table indeed has an "id" column, then there might be an issue with your database schema or the way you've set up your data provider in Refine. Please double-check your database schema and your Refine setup. If you're still having issues, you might want to look into the Refine documentation (https://refine.dev/docs) or ask for help in the Refine GitHub Discussions (https://github.com/pankod/refine/discussions) for more specific guidance. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai does the id columb need to be named id?
kapa.ai
kapa.ai3mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- No, the primary key column in your database does not need to be named "id". Refine allows you to specify a custom primary key column name using the meta property and idColumnName attribute in your resource definition. Here's an example of how you can specify a custom primary key column name:
{
name: "currencies",
list: "/administration/currencies",
show: "/administration/currencies/show/:id",
meta: {
parent: 'administration',
canDelete: false,
idColumnName: "code",
},
}
{
name: "currencies",
list: "/administration/currencies",
show: "/administration/currencies/show/:id",
meta: {
parent: 'administration',
canDelete: false,
idColumnName: "code",
},
}
In this example, the primary key column for the "currencies" resource is set to "code" instead of "id". However, please note that this feature is only implemented in the @refinedev/supabase data provider. If you're using a different data provider, you'll need to customize it to support meta.idColumnName or any other meta you wish to use. You can use the swizzle command to customize the data provider (source (https://github.com/refinedev/refine/issues/5356)). Also, note that the Inferencer components in Refine do not currently use the meta property of the resource definition. They use the meta prop that is passed to the component itself (source (https://github.com/refinedev/refine/issues/5356)). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the primary key is name project_id what should i adjust in my code?
kapa.ai
kapa.ai3mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- If your primary key is named project_id, you can specify this in the useMany hook by passing the meta property with idColumnName attribute set to "project_id". Here's how you can do it:
const {{ data: projectData, isFetching }} = useMany({{
resource: "projects",
ids: project_id,
meta: {{
idColumnName: "project_id",
}},
}});
const {{ data: projectData, isFetching }} = useMany({{
resource: "projects",
ids: project_id,
meta: {{
idColumnName: "project_id",
}},
}});
In this example, the useMany hook will look for the project_id column in the "projects" table instead of the "id" column. However, please note that this feature is only implemented in the @refinedev/supabase data provider. If you're using a different data provider, you'll need to customize it to support meta.idColumnName or any other meta you wish to use. You can use the swizzle command to customize the data provider (source (https://github.com/refinedev/refine/issues/5356)).

@kapa.ai how can i upload to the images bucket in supabase?
kapa.ai
kapa.ai3mo ago
Let me check the knowledge base for you. One moment! :books: ---------------------- You can upload files to the Supabase storage using the supabaseClient.storage.from() method. Here's an example of how you can do this:
const { error } = await supabaseClient.storage
.from("images") // specify the bucket name
.upload(fileUrl, file, {
cacheControl: "3600",
upsert: true,
});
const { error } = await supabaseClient.storage
.from("images") // specify the bucket name
.upload(fileUrl, file, {
cacheControl: "3600",
upsert: true,
});
In this example, fileUrl is the path where you want to store the file in the bucket, and file is the file you want to upload. The upload method also accepts an options object where you can specify the cacheControl and upsert options. If the upload is successful, the error will be null. If there's an error during the upload, the error will contain the error message. For more information, you can refer to the Refine documentation on adding an Edit page (https://refine.dev/docs/data/packages/supabase#adding-an-edit-page) and the Supabase documentation on file uploads (https://supabase.io/docs/guides/storage#uploading-files). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
