useTable with complex response
Hello, first time here, and first project with refine!
I'm trying to get some data from an api (prometheus alertmanager), and I ran into some issues.
I can get the data from the API, but my problem is with parsing it correctly.
I couldn't find how to either - 1) map the values into a different simple structure (e.g., map fingerprint to id, labels.* to * and so on), or 2) specifiy dataIndex in <Table.Column> props so that it reads the nested values.
An example response can look like this:
{
"annotations": {
"description": "Disk usage is more than 80%\n VALUE = 81.5100154083205\n LABELS = map[instance:some-ip:port job:win_env site:site-name volume:volume-name]",
"summary": "Windows Server disk Space Usage (instance some-ip:port)"
},
"endsAt": "2024-12-29T12:12:04.162Z",
"fingerprint": "3cf84c3fb282409f",
"receivers": [
{
"name": "mail"
}
],
"startsAt": "2024-12-25T06:36:04.162Z",
"status": {
"inhibitedBy": [],
"silencedBy": [],
"state": "active"
},
"updatedAt": "2024-12-29T12:08:04.159Z",
"generatorURL": "generator_url/graph?g0.expr=80+%3C+%28100+-+100+%2A+%28%28windows_logical_disk_free_bytes+%2F+1024+%2F+1024%29+%2F+%28windows_logical_disk_size_bytes+%2F+1024+%2F+1024%29%29%29+%3C+85&g0.tab=1",
"labels": {
"alertname": "WindowsServerDiskSpaceUsage",
"instance": "some-ip:port",
"job": "win_env",
"severity": "minor",
"site": "site-name",
"volume": "volume-name"
}
}

Hi @Stormlight. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
To address your issue with parsing complex response data from the Prometheus Alertmanager API using refine's
useTable
hook and Ant Design's Table component, I can provide some guidance based on the available knowledge sources.
1. Mapping values to a different structure:
You can use the select
function in the queryOptions
of useTable
to transform the data before it's used by the table. Here's how you can do this:
This approach is mentioned in the useTable FAQ (https://refine.dev/docs/data/hooks/use-table/#faq) section.
2. Specifying dataIndex for nested values:
If you prefer to keep the original structure and access nested values, you can use dot notation in the dataIndex
prop of <Table.Column>
. For example:
This approach is based on the Ant Design Table component's capabilities, which refine's useTable
hook integrates with.
For more complex rendering scenarios, you can use the render
prop of <Table.Column>
to customize how the data is displayed:
These solutions should help you handle the complex response structure from your Prometheus Alertmanager API. For more detailed information on using useTable
with refine and Ant Design, you can refer to the useTable documentation for Ant Design (https://refine.dev/docs/ui-integrations/ant-design/hooks/use-table/).

@kapa.ai What about the following scenario...
Let's say I have an API endpoint for folders, which can have children (other folders, or some other resource like files). However, the API doesn't return the children.
Now, let's say I want to be able to see the children under "show" for example. What would be the correct approach for something like that? since it requires multiple API calls.
The final result I'm trying to achieve is to be able to browse the folder structure (maybe with something like Menu) until I get to the desired file, and then display the file contents.
Let me check the knowledge base for you again. One moment! :books:
----------------------
To handle the scenario you've described, where you want to display a folder structure with children that are not returned in the initial API response, you can use a combination of Refine's hooks and components. Here's an approach you can take:
1. Use
useShow
for the initial folder data:
First, use the useShow
hook to fetch the initial folder data. This will give you the basic information about the current folder.
2. Use useList
or useMany
for children:
After getting the folder data, you can use useList
or useMany
to fetch the children (subfolders or files) of the current folder. The choice between useList
and useMany
depends on how your API is structured.
3. Implement a recursive component:
Create a recursive component that can render both folders and files. This component will use the data fetched from steps 1 and 2.
Here's a basic example of how you might implement this:
This approach allows you to recursively render the folder structure. When a user clicks on a folder, you can either expand it in place or navigate to a new page for that folder.
For the final step of displaying file contents, you can create a separate FileShow
component that fetches and displays the file data when a file is selected.
To optimize performance, you might want to consider:
1. Implementing pagination or virtual scrolling for folders with many children.
2. Using useQuery
with enabled
option to fetch data only when needed (e.g., when a folder is expanded).
For more details on data fetching in Refine, you can refer to the Data Fetching documentation (https://refine.dev/docs/guides-concepts/data-fetching/overview/).
This solution provides a flexible way to browse the folder structure and display file contents, accommodating the need for multiple API calls as you navigate through the hierarchy.

@kapa.ai I'm trying to implement this approach, and I ran into some UI issue. I'm trying to use Menu only for the top level to display the root folders, and then Menu.SubMenu for the children folders. I can populate the items, but no matter what I've tried, when I hover/click a sub-folder (e.g., OS folder in the root location can contain Windows and Linux subfolders, each having multiple dashboards), all the subfolder menus are expanded, instead of only the selected one. Why might that happen?
I also need to maintain a selectedFile state, so I can then display it properly. (outside of the Menu).
Let me check the knowledge base for you again. One moment! :books:
----------------------
Based on your description, it seems you're encountering an issue with the Ant Design Menu component where all submenus are expanding simultaneously instead of just the selected one. This behavior is not the default for Ant Design's Menu, so let's explore some possible reasons and solutions.
1. Controlled vs Uncontrolled Menu:
The issue might be related to how you're managing the open state of the Menu. Ant Design's Menu can be either controlled or uncontrolled. In a controlled Menu, you manage the open state yourself, while in an uncontrolled Menu, Ant Design handles it internally.
To implement a controlled Menu, you can use the
openKeys
and onOpenChange
props. Here's an example of how you might structure this:
2. Unique Keys:
Ensure that each Menu.Item and SubMenu has a unique key
prop. If keys are not unique, it can cause unexpected behavior.
3. Data Structure:
Make sure your data structure correctly represents the hierarchy. Each folder should have a unique identifier and a children array containing its subfolders and files.
4. Performance Considerations:
For large folder structures, consider implementing lazy loading of subfolders. You can use the onTitleClick
prop of SubMenu to fetch children only when a folder is opened.
5. Maintaining Selected File State:
As shown in the example above, you can maintain the selectedFile
state at the top level of your component. When a file is clicked, update this state. You can then use this state to display the file contents outside of the Menu.
If you're still experiencing issues after implementing these suggestions, it would be helpful to see your current implementation. The problem might be in how the data is structured or how the Menu is being rendered.
For more detailed information on using Ant Design's Menu component with Refine, you can refer to the Ant Design Menu documentation (https://ant.design/components/menu) and Refine's Ant Design integration guide (https://refine.dev/docs/ui-integrations/ant-design/).

@kapa.ai In the last reply you've said: 3. Data Structure:
Make sure your data structure correctly represents the hierarchy. Each folder should have a unique identifier and a children array containing its subfolders and files.
That's however the exact issue I'm trying to solve here. I don't have the children prepopulated from the API response, as I've mentioned in my original question.
And if I try to use a hook such as useList or use Custom inside the recursive components, I get errors about hooks being called too many times or something like that.
How can I solve this? Can I define some custom hook/method in the dataProvider that will build the folder hierarchy? Or is there another way to fix the problem?
Let me check the knowledge base for you again. One moment! :books:
----------------------
I apologize for the confusion in my previous response. You're right, and I should have paid more attention to your original question about the API not returning the children. Let's address this issue properly.
To solve the problem of building a folder hierarchy when the API doesn't return children, we can implement a custom method in the data provider to fetch and build the hierarchy. This approach avoids calling hooks inside recursive components, which can lead to the errors you've encountered.
Here's how you can implement this:
1. Create a custom method in your data provider:
First, add a custom method to your data provider to fetch the folder hierarchy. This method will recursively fetch children for each folder.
2. Use the custom method with
useCustom
hook:
Now you can use the useCustom
hook to call this custom method and fetch the entire folder hierarchy.
This approach has several advantages:
1. It avoids calling hooks inside recursive components, preventing the "too many re-renders" error.
2. It fetches the entire hierarchy in one go, which can be more efficient than fetching each level separately.
3. It allows you to cache the entire hierarchy using React Query's caching mechanism.
However, keep in mind that this approach might not be suitable for very large folder structures, as it fetches the entire hierarchy at once. For large structures, you might want to consider a lazy-loading approach where you fetch children only when a folder is expanded.
For more information on using custom methods with Refine, you can refer to the useCustom hook documentation (https://refine.dev/docs/data/hooks/use-custom/).
This solution should help you build and display your folder hierarchy without running into hook-related errors.
