Query Resource by specific field
I need a way of retrieving a resource by a field other than the Id.
For example if I have a Resource called customer which has a telephoneNumber field, I need to be able to query the record which has a specific telephoneNumber value.

Hi @jacktrent. 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 way to fetch data based on specific fields using filters. You can use the
filters
prop in the data fetching methods to specify the field and the value you want to filter by. Here is an example of how you can do this:
In this example, filters
is an array where each item is an object that specifies the field to filter by and the value to match. The field
property is the name of the field, and the value
property is the value to match.
So, if you want to fetch a customer with a specific telephone number, you can do something like this:
Then, you can pass this filters
array to the data fetching method.
Please note that the actual implementation may vary depending on the data provider you are using. You can refer to the Data Fetching (https://refine.dev/docs/guides-concepts/data-fetching#relationships) section of the Refine documentation for more information.

@kapa.ai Can I have an example of this which uses the useOne hook?
Let me check the knowledge base for you. One moment! :books:
----------------------
I'm sorry for any confusion, but the
useOne
hook in Refine is designed to fetch a single record based on its id
property. It doesn't support fetching a record based on other fields directly.
Here's how you typically use the useOne
hook:
In this example, useOne
is used to fetch a post with an id
of 1.
If you need to fetch a record based on a field other than id
, you might need to create a custom hook that uses the useQuery
or useCustom
hook under the hood, or modify your backend to support fetching a record by a field other than id
.
For more information, you can refer to the useOne (https://refine.dev/docs/data/hooks/use-one/) and useCustom (https://refine.dev/docs/data/hooks/use-custom/) sections of the Refine documentation.

@kapa.ai Create an example using the useCustom hook
Let me check the knowledge base for you. One moment! :books:
----------------------
Sure, here's an example of how you can use the
useCustom
hook to send a custom query request. In this example, we're sending a GET request to an endpoint /posts-unique-check
:
In this example, useApiUrl
is used to get the base URL of the API endpoint. The useCustom
hook is then used to send a request to the endpoint. The useCustom
hook expects a url
, method
, and config
properties. The url
property accepts the endpoint URL, the method
property accepts the type of method of the endpoint (a "get" endpoint in this case), and the config
property accepts values like the headers
for the endpoint, query
parameters, and more.
When properties are changed, the useCustom
hook will trigger a new request. You can then use the data
and isLoading
variables in your component to display the data or a loading indicator.
For more information, you can refer to the useCustom (https://refine.dev/docs/data/hooks/use-custom/) section of the Refine documentation.

@kapa.ai create a complete example on how to query a resource by the telephone field
Let me check the knowledge base for you. One moment! :books:
----------------------
Sure, here's an example of how you can use the
useCustom
hook to fetch a customer record based on a telephone number:
In this example, useCustom
is used to send a getList
request to the customers
resource with a filter for the telephoneNumber
field. The data
variable will then contain the customer record that matches the telephone number.
Please note that the actual implementation may vary depending on the data provider you are using and how it handles filters. You may need to adjust the query
property accordingly.
For more information, you can refer to the useCustom (https://refine.dev/docs/data/hooks/use-custom/) section of the Refine documentation.

Hey @jacktrent, hope the bot helped. You have couple of options to achieve this;
- Using
useList
and filters
to query the field you wanted
- You can customize the getOne
method of your data provider and use meta
fields to instruct it to do custom queries/requests.
- You can use the useCustom
hook to make custom requests to your API with help of your data provider.
