Table filtering where data column is an array of strings.
I have a form that allows users to select multiple values to be used as tags. The column is called industry and is set as a text[] datatype in Supabase. Data entry for the user works as expected and displays correctly.
I'm having an issue when attempting to apply a filter.
I get the following error when selecting a value to filter by, with the same result whether it's 1 value or more.

Hi @James. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
It seems like you're trying to filter an array column with an array in Supabase, which is currently not supported by Refine. This issue has been recognized and there's an open Github issue (https://github.com/refinedev/refine/issues/5902) discussing the implementation of this feature.
The proposed solution is to add
ina
and nina
to the CrudFilter
and map it to query.contains
in the Supabase data provider to support this case. However, this feature has not been implemented yet.
For now, you might need to implement a custom solution to handle this case. You can keep track of the Github issue for updates on when this feature will be available.

@kapa.ai It looks like this was implemented: Filter array column by array (ina and nina operators) https://discord.com/channels/837692625737613362/973871286281445376/1243541318312001627
How would I adjust my column filter to account for the new operator?
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, the feature to filter array columns by array using
ina
and nina
operators has been implemented in Refine. You can adjust your column filter to use these new operators.
Here's how you can modify your column filter to use the ina
operator:
In this example, the transform
function in the useTable
hook is used to modify the filter logic to use the ina
operator for the industry
field. This will allow you to filter the industry
column by an array of values.
For more details, you can refer to the pull request (https://github.com/refinedev/refine/pull/5922) that implemented this feature.

@kapa.ai I get the following error:
Let me check the knowledge base for you. One moment! :books:
----------------------
It looks like the
transform
function is not a valid property for the filters
object in the useTable
hook. Instead, you should directly specify the filter with the ina
operator in the initial
filters.
Here's how you can adjust your column filter to use the ina
operator correctly:
In this example, the initial
filters are set directly in the useTable
hook with the ina
operator for the industry
field. This should allow you to filter the industry
column by an array of values.
For more information, you can refer to the CrudFilters interface documentation (https://refine.dev/docs/core/interface-references/#crudfilters).

@kapa.ai Hmm ok, it's not quite working as expected. Here's what I'm setting my filters to:
The results I get back show any entry that has both "Business Services" AND "Energy" included in the industry field but no results that only have one of those. How can I adjust so that if an entry has "Business Services" OR "Energy" included, they'll also be listed?
Let me check the knowledge base for you. One moment! :books:
----------------------
To achieve the desired behavior where entries are listed if they have either "Business Services" OR "Energy" included in the
industry
field, you need to ensure that the filter logic is correctly applied. The ina
operator should work for this purpose, but it seems like there might be an issue with how the filter is being interpreted.
Here's how you can adjust your filters to ensure that entries with either "Business Services" OR "Energy" are included:
In this example, the ina
operator is used to filter the industry
field by an array of values. The onChange
handler in the Select
component ensures that the selected values are correctly set and the filter is applied.
For more information, you can refer to the CrudFilters interface documentation (https://refine.dev/docs/core/interface-references/#crudfilters). If the issue persists, you might want to check the implementation details or consult the Refine community for further assistance.

@kapa.ai Still no luck, here's what the url looks like:
It's still only showing results that have BOTH selected values for industry.
Let me check the knowledge base for you. One moment! :books:
----------------------
It looks like the
ina
operator is not behaving as expected for your use case. The ina
operator should indeed filter entries that have any of the specified values in the array, but it seems to be requiring all values to be present.
To achieve the desired behavior, you might need to use a custom filter logic. Unfortunately, the provided knowledge sources do not include a direct solution for this specific issue. However, you can try the following approach to manually handle the filtering logic:
1. Custom Filter Logic: Implement a custom filter function that checks if any of the selected values are present in the industry
array.
Here's an example of how you can implement this:
In this example, the handleIndustryFilterChange
function sets a custom filter for the industry
field. You can then implement the custom filter logic on the server side to handle the custom
operator and filter entries that have any of the selected values in the industry
array.
For more information on custom filters, you can refer to the Refine documentation (https://refine.dev/docs/core/interface-references/#crudfilters).
If you need further assistance, you might want to consult the Refine community or check the Github issue (https://github.com/refinedev/refine/issues/5902) for updates on this feature.

@kapa.ai After doing some more digging, I've realized what I'm looking for is an array_overlap operator. Here's a couple of examples.
Both return a combination of entries that have either 'Business Services' OR 'Energy' included, not just including ALL values. Can you suggest a way to implement it in a way that would work with filtering an Ant Design table?
Let me check the knowledge base for you. One moment! :books:
----------------------
To implement the
array_overlap
operator for filtering an Ant Design table using Refine, you can use the overlaps
operator provided by Supabase. This will allow you to filter entries that have either 'Business Services' OR 'Energy' included in the industry
field.
Here's how you can adjust your column filter to use the overlaps
operator:
1. Custom Filter Logic: Implement a custom filter function that uses the overlaps
operator.
Here's an example of how you can implement this:
In this example, the handleIndustryFilterChange
function sets a custom filter for the industry
field using the overlaps
operator. This will allow you to filter entries that have any of the selected values in the industry
array.
For more information on custom filters, you can refer to the Refine documentation (https://refine.dev/docs/core/interface-references/#crudfilters).

@kapa.ai So the "overlaps" operator doesn't exist and would need to be added in.
Let me check the knowledge base for you. One moment! :books:

To achieve the desired behavior of filtering entries that have either "Business Services" OR "Energy" included in the
industry
field, you can use the array_overlap
operator. Since the overlaps
operator doesn't exist in Refine, you can implement a custom solution to handle this case.
Here's how you can adjust your column filter to use a custom filter logic that mimics the array_overlap
behavior:
1. Custom Filter Logic: Implement a custom filter function that checks if any of the selected values are present in the industry
array.
