Hi @natztheking. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Refine provides a
useTable
hook that has a pagination feature. The pagination is done by passing the current
and pageSize
keys to the pagination
object. The current
is the current page, and the pageSize
is the number of records per page. By default, the current
is 1 and the pageSize
is 10. You can change default values by passing the pagination.current
and pagination.pageSize
props to the useTable
hook. You can also change the current
and pageSize
values by using the setCurrent
and setPageSize
functions that are returned by the useTable
hook. Every change will trigger a new fetch.
By default, pagination happens on the server side. If you want to do pagination handling on the client side, you can pass the pagination.mode
property and set it to "client". Also, you can disable the pagination by setting it to "off".
Here is an example of how you can use the useTable
hook for pagination:
As for the backend API, it should be designed to accept parameters for the current page and the number of records per page, and return the corresponding records. The exact implementation would depend on the specific backend technology and database you are using.
For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination).
Please note that the backend API should also handle the case where the client-side pagination is used. In this case, the backend should return all records and the client-side code will handle the pagination.

using simple rest api
@kapa.ai using simple rest api
Let me check the knowledge base for you. One moment! :books:
----------------------
When using the Simple REST data provider with Refine, the backend API should be designed to handle pagination parameters. The Simple REST data provider sends HTTP requests to the API with query parameters for pagination, sorting, and filtering.
For pagination, the Simple REST data provider sends the
page
and pageSize
parameters in the URL. The page
parameter represents the current page number, and the pageSize
parameter represents the number of records per page.
Here's an example of how the URL might look for a getList
request:
In this case, the backend API should return the first page of records, with 10 records per page.
The backend API should also return the total number of records in the X-Total-Count
header. This is used by Refine to calculate the total number of pages.
Here's an example of how the backend API might handle a getList
request:
In this example, db
is a lowdb instance, which is a small local JSON database. This is just an example, and the actual implementation would depend on your specific backend technology and database.
For more information, you can refer to the Refine documentation on the Simple REST data provider (https://refine.dev/docs/data/packages/simple-rest).

@kapa.ai I have changed it but still the front end doesnt paginate
Let me check the knowledge base for you. One moment! :books:
----------------------
If you've set up your backend correctly and you're still having issues with pagination on the frontend, there could be a few reasons why this is happening. Here are a few things you can check:
1. Check your
useTable
hook: Make sure you're using the useTable
hook correctly in your component. The useTable
hook should be used with the pagination
prop. Here's an example:
2. Check your API response: Make sure your API is returning the correct data and headers. The API should return the data for the current page in the response body, and the total count of records in the X-Total-Count
header.
3. Check your API request: Look at the network tab in your browser's developer tools to see the request that's being sent to your API. The request should include the page
and pageSize
parameters in the URL.
4. Check your error messages: If there are any error messages in your browser's console, they could provide a clue as to what's going wrong.
If you're still having issues after checking these things, it would be helpful to have more specific information about what's happening. For example, what exactly happens when you try to paginate? Are there any error messages? What does the API request and response look like?
For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination) and the Refine documentation on the Simple REST data provider (https://refine.dev/docs/data/packages/simple-rest).

@kapa.ai Can you give a front end
Let me check the knowledge base for you. One moment! :books:
----------------------
Sure, here's an example of how you can use the
useTable
hook in a Refine project to create a paginated table. This example assumes you have a resource named "posts".
In this example, useTable
is used to create a table for the "posts" resource. The columns
prop defines the columns of the table. The pagination
prop is used to configure the pagination. The defaultPageSize
is the initial page size, and pageSizeOptions
are the options for page size that the user can select.
The tableProps
and paginationProps
returned by useTable
are spread into the Table
and Table.Pagination
components to apply the pagination behavior.
Please note that this is a basic example and you might need to adjust it according to your needs. For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination).

@kapa.ai This is the one i use
const { tableProps } = useTable({
syncWithLocation: true,
pagination: {
mode: "server",
},
});
return (
<List>
<Table {...tableProps} rowKey="_id">
{/* <Table.Column dataIndex="id" title="ID" /> */}
<Table.Column dataIndex="clientname" title="Client Name" />
<Table.Column dataIndex="jobname" title="Job Name" />
<Table.Column dataIndex="invoiceno" title="Invoice Number" />
<Table.Column dataIndex="jobstatus" title="Job Status" />
<Table.Column
dataIndex="createdAt"
title="Created At"
render={(value: any) => <DateField value={value} />}
/>
<Table.Column
title="Actions"
dataIndex="actions"
render={(: any, record: BaseRecord) => (
<Space>
<EditButton hideText size="small" recordItemId={record._id} />
<ShowButton hideText size="small" recordItemId={record._id} />
<DeleteButton hideText size="small" recordItemId={record._id} />
</Space>
)}
/>
</Table>
</List>
);
};
Let me check the knowledge base for you. One moment! :books:
----------------------
Your code seems correct for setting up a server-side paginated table with Refine's
useTable
hook. The syncWithLocation: true
option will synchronize the table's state (including pagination) with the URL. The pagination: { mode: "server" }
option indicates that pagination is handled on the server side.
If you're still having issues with pagination, here are a few things you can check:
1. Check your API response: Make sure your API is returning the correct data and headers. The API should return the data for the current page in the response body, and the total count of records in the X-Total-Count
header.
2. Check your API request: Look at the network tab in your browser's developer tools to see the request that's being sent to your API. The request should include the page
and pageSize
parameters in the URL.
3. Check your error messages: If there are any error messages in your browser's console, they could provide a clue as to what's going wrong.
If you're still having issues after checking these things, it would be helpful to have more specific information about what's happening. For example, what exactly happens when you try to paginate? Are there any error messages? What does the API request and response look like?
For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination) and the Refine documentation on the Simple REST data provider (https://refine.dev/docs/data/packages/simple-rest).

@kapa.ai was there any update recently on useTable it is not using the total-x-count in response headers
Let me check the knowledge base for you. One moment! :books:
----------------------
Refine's
useTable
hook uses the X-Total-Count
header to determine the total number of pages for pagination. This is a standard practice in many REST APIs. If the useTable
hook is not recognizing the X-Total-Count
header, there could be a few reasons:
1. Check the header name: Make sure the header name is spelled and capitalized correctly as X-Total-Count
.
2. Check the header value: The X-Total-Count
header should contain the total number of records as a number. Make sure the value is correct and is being sent as a number, not a string.
3. Check your API configuration: Some servers or frameworks may require specific configuration to allow custom headers like X-Total-Count
. Make sure your server is configured to allow this header.
4. Check your CORS configuration: If your API is on a different domain, you may need to configure CORS (Cross-Origin Resource Sharing) to allow the X-Total-Count
header. The Access-Control-Expose-Headers
header can be used to expose the X-Total-Count
header to the browser.
If you're still having issues, it would be helpful to have more specific information about your API and how you're using the useTable
hook.
For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination) and the Refine documentation on the Simple REST data provider (https://refine.dev/docs/data/packages/simple-rest).

@kapa.ai const listJobs = asyncHandler(async (req, res) => {
try {
// Extract pagination parameters
let { page = 1, pageSize = 10 } = req.query;
page = parseInt(page);
pageSize = parseInt(pageSize);
// Calculate offset
const offset = (page - 1) * pageSize;
// Retrieve jobs with pagination
const jobs = await Job.find()
.sort({ createdAt: -1 })
.skip(offset)
.limit(pageSize);
// Retrieve total count of jobs
const totalCount = await Job.countDocuments();
// Send response with jobs and pagination metadata
res.set("X-Total-Count", totalCount);
res.json(jobs);
} catch (error) {
console.error("Error retrieving jobs:", error);
res.status(500).json({ error: "Internal Server Error" });
}
});
Let me check the knowledge base for you. One moment! :books:
----------------------
Your backend API code seems to be correctly set up for pagination. You're extracting the
page
and pageSize
parameters from the request query, calculating the offset, and using the skip
and limit
functions to retrieve the paginated data. You're also correctly setting the X-Total-Count
header with the total count of jobs.
If you're still having issues with pagination on the frontend, you might want to check the following:
1. Check the request: Make sure the frontend is sending the correct page
and pageSize
parameters in the request.
2. Check the response: Make sure the response includes the X-Total-Count
header and the paginated data.
3. Check for errors: If there are any errors in the console, they could provide a clue as to what's going wrong.
If you're using Refine's useTable
hook on the frontend, it should automatically handle the pagination based on the page
and pageSize
parameters and the X-Total-Count
header.
Here's an example of how you can use the useTable
hook:

@contributor Help
@kapa.ai can i get the Total-Count-Data from the use table
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, you can get the total count of data from the
useTable
hook. The useTable
hook returns a pageCount
value, which represents the total number of pages. If you know the number of items per page (which is determined by the pageSize
value), you can calculate the total number of items.
Here's an example:
In this example, totalCount
will give you the total number of items. Please note that this is an approximation. If the total number of items is not a multiple of pageSize
, the last page will contain fewer items than pageSize
.
For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination).

@kapa.ai is there any way to check whether we are using the total count from headers of the response
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, you can check whether the total count from the headers of the response is being used by inspecting the network requests in your browser's developer tools.
Here's how you can do it:
1. Open your application in your browser.
2. Open the developer tools (usually by pressing F12 or right-clicking anywhere on the page and selecting "Inspect").
3. Go to the "Network" tab.
4. In your application, perform an action that triggers a network request (for example, loading a page that uses the
useTable
hook).
5. In the "Network" tab, find the request in the list. It should be a GET request to the URL of your resource (for example, "/posts").
6. Click on the request to view its details.
7. In the "Headers" section, look for the "X-Total-Count" header in the "Response Headers" subsection.
If the "X-Total-Count" header is present and has a value, that means the total count from the headers of the response is being used.
Please note that the exact steps may vary depending on your browser. The steps above are generally applicable to most modern browsers like Chrome, Firefox, and Edge.
For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination) and the Refine documentation on the Simple REST data provider (https://refine.dev/docs/data/packages/simple-rest).

@kapa.ai The headers are present but it is not being used
Let me check the knowledge base for you. One moment! :books:
----------------------
If the
X-Total-Count
header is present in the response but it seems like it's not being used, there might be an issue with how the data provider is handling the response.
Refine's built-in data providers, such as the Simple REST data provider, are designed to use the X-Total-Count
header for pagination. If you're using a custom data provider, you'll need to make sure it's correctly handling the X-Total-Count
header.
Here's an example of how a data provider might handle the X-Total-Count
header in a getList
function:
In this example, the getList
function sends a GET request to the API with pagination parameters. It then retrieves the X-Total-Count
header from the response and returns it as the total
in the result.
If you're still having issues, it would be helpful to have more specific information about your data provider and how you're using the useTable
hook.
For more information, you can refer to the Refine documentation on data providers (https://refine.dev/docs/data/data-providers) and the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination).

----------------------
The
getList
function you provided is a method in a data provider for the Refine framework. It's used to fetch a list of resources from your API with support for pagination, sorting, and filtering.
Here's a breakdown of what it does:
1. It constructs the URL for the API request using the resource
parameter.
2. It extracts the current
page, pageSize
, and mode
from the pagination
parameter. If pagination
is not provided, it defaults to { current: 1, pageSize: 10, mode: "server" }
.
3. It generates a query string for the API request. If mode
is "server"
, it includes _start
and _end
parameters for pagination. If sorters
is provided, it includes _sort
and _order
parameters for sorting.
4. It sends a GET request to the API with the constructed URL and query string.
5. It retrieves the X-Total-Count
header from the response and uses it as the total
in the result. If the X-Total-Count
header is not present, it defaults to the length of the data.
Here's the code:
For more information, you can refer to the Refine documentation on data providers (https://refine.dev/docs/data/data-provider#getlist-) and the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination).

@kapa.ai When console log it show total as 10 but i have 16 in x-total-count
const { data, isFetched, isLoading } = tableQueryResult;
console.log(data);
Let me check the knowledge base for you. One moment! :books:
----------------------
The
data
variable in your console log refers to the data for the current page, not the total data set. The length of data
will be equal to the page size, not the total count of records. In your case, it seems like the page size is set to 10, so you're seeing 10 records in data
.
The X-Total-Count
header, which you mentioned is 16, represents the total count of records in the entire data set, not just the current page.
If you want to log the total count of records, you should look at the total
field returned by the useTable
hook, not the data
field. Here's how you can do it:
In this example, total
will give you the total count of records, which should be 16 according to your X-Total-Count
header.
For more information, you can refer to the Refine documentation on the useTable hook (https://refine.dev/docs/data/hooks/use-table#pagination).

@kapa.ai it show undefined
Let me check the knowledge base for you. One moment! :books:
----------------------
I'm sorry for the confusion, but the
useTable
hook in Refine does not directly provide the total count of records. My previous response was incorrect.
The useTable
hook does not expose the total count of records directly. It internally uses this information to handle pagination, but it does not provide it as part of its return value.
If you need to access the total count of records, you might need to use a different hook or method depending on your specific use case. For example, you could use the useGetList
hook, which does provide the total count of records.
Here's an example:
In this example, total
will give you the total count of records.
Please note that this might not be the best solution depending on your specific use case. If you provide more details about what you're trying to achieve, I might be able to give a more accurate answer.
For more information, you can refer to the Refine documentation on the useGetList hook (https://refine.dev/docs/data/hooks/use-get-list).
