How to alter the key that is added to the query when using a custom filter?

When using a filter that is prebuilt, for example for dates „is on or before” will add to the column’s name „_lte”. Hence if my column is named „Date” and i apply the „is on or before filter” and specify date to be 1.01.2024, then the query is as follows: „Date_lte: 1.01.2024”. I had to implement my own filter for a date interval, from and to with two values. I got to the point when both are sent in one query and this works, but the issue is that the keys for both are just „Date” and I cannot differentiate between the two, nor what filter is even sed. What I currently get when putting two dates is: Date: 1.01.2024 Date: 2.01.2024 And this is a single query. How can I add something similar to what the „_lte” does, also per date field? (So I would want to have: Date_from: 1.0.1.2024 Date_to: 2.01.2024 As a single query) If something is unclear or more is required let me know. Much appreciated for your time on reading this already.

Hi @andrulonis. 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 customize the way filters are handled in your data provider. The data provider interface provides a way to map the filters from refine to the format that your API accepts. Here is an example of how you can handle this in your data provider:

const queryFilters: { [key: string]: string } = {};  
  
if (filters) {  
  filters.map((filter) => {  
    if (filter.operator === "or" || filter.operator === "and") {  
      throw new Error(  
        `[@refinedev/simple-rest]: /docs/data/data-provider#creating-a-data-provider`,  
      );  
    }  
  
    if ("field" in filter) {  
      const { field, operator, value } = filter;  
  
      if (field === "q") {  
        queryFilters[field] = value;  
        return;  
      }  
  
      const mappedOperator = mapOperator(operator);  
      queryFilters[`${field}${mappedOperator}`] = value;  
    }  
  });  
}  
  
return queryFilters;

const queryFilters: { [key: string]: string } = {};  
  
if (filters) {  
  filters.map((filter) => {  
    if (filter.operator === "or" || filter.operator === "and") {  
      throw new Error(  
        `[@refinedev/simple-rest]: /docs/data/data-provider#creating-a-data-provider`,  
      );  
    }  
  
    if ("field" in filter) {  
      const { field, operator, value } = filter;  
  
      if (field === "q") {  
        queryFilters[field] = value;  
        return;  
      }  
  
      const mappedOperator = mapOperator(operator);  
      queryFilters[`${field}${mappedOperator}`] = value;  
    }  
  });  
}  
  
return queryFilters;

In this example, the mapOperator function is used to map the operator from refine to the format that the API accepts. You can customize this function to handle your custom date interval filter. For example, you can check if the field is "Date" and if the operator is your custom operator, then you can add "_from" or "_to" to the field name. Please note that this is just an example and you might need to adjust it to fit your specific needs. You can find more information about this in the refine documentation (https://refine.dev/docs/guides-concepts/data-fetching/data-provider-interface). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how can you differentiate in this file for filters between the two fields?

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- In the data provider, you can differentiate between the two fields by checking the field property of the filter. Here is an example:

const dataProvider = (): DataProvider => ({  
 getList: async ({ resource, pagination, filters, sorters }) => {  
 if (filters) {  
 filters.map((filter) => {  
 if (  
 filter.operator !== "or" &&  
 filter.operator !== "and" &&  
 "field" in filter  
 ) {  
 // Handle your logical filters here  
 if (filter.field === "Date_from") {
   // Handle Date_from filter
 } else if (filter.field === "Date_to") {
   // Handle Date_to filter
 }
 } else {  
 // Handle your conditional filters here  
 }  
 });  
 }  
 },  
});

const dataProvider = (): DataProvider => ({  
 getList: async ({ resource, pagination, filters, sorters }) => {  
 if (filters) {  
 filters.map((filter) => {  
 if (  
 filter.operator !== "or" &&  
 filter.operator !== "and" &&  
 "field" in filter  
 ) {  
 // Handle your logical filters here  
 if (filter.field === "Date_from") {
   // Handle Date_from filter
 } else if (filter.field === "Date_to") {
   // Handle Date_to filter
 }
 } else {  
 // Handle your conditional filters here  
 }  
 });  
 }  
 },  
});

In this example, we are checking if the field property of the filter is "Date_from" or "Date_to" and handling them accordingly. You can replace the comments with your own logic to handle these filters. Please note that this is just an example and you might need to adjust it to fit your specific needs. You can find more information about this in the refine documentation (https://refine.dev/docs/advanced-tutorials/data-provider/handling-filters#handle-filters-in-a-data-provider). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Where should i set this field property then? On the <DatePicker>?

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you should set the field property on the <DatePicker> component. The field property is used to specify the name of the field that this component represents. Here is an example of how you can use it:

<DatePicker
  field="Date_from"
  label="From"
  placeholder="Select a start date"
/>

<DatePicker
  field="Date_to"
  label="To"
  placeholder="Select an end date"
/>

<DatePicker
  field="Date_from"
  label="From"
  placeholder="Select a start date"
/>

<DatePicker
  field="Date_to"
  label="To"
  placeholder="Select an end date"
/>

In this example, we have two <DatePicker> components. One for the start date with the field name "Date_from" and one for the end date with the field name "Date_to". When these components are used in a form and the form is submitted, the values of these fields will be included in the form data with the specified field names. You can find more information about this in the refine documentation (https://refine.dev/docs/api-references/components/form-components/date-picker). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how do you change the styling of the tooltip that is used when clicking on filter

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To change the styling of the tooltip used when clicking on a filter, you would need to modify the CSS for the tooltip component. In the case of Refine, the tooltip styling can be found in the styles.module.css file of the tooltip component. Here's an example of how you can modify the tooltip styling:

.tooltip {
    z-index: var(--ifm-z-index-overlay);
    /* Add your custom styles here */
}

.tooltipContainer {
    /* Add your custom styles here */
}

.tooltipContent {
    /* Add your custom styles here */
}

.tooltipArrow {
    /* Add your custom styles here */
}

.tooltip {
    z-index: var(--ifm-z-index-overlay);
    /* Add your custom styles here */
}

.tooltipContainer {
    /* Add your custom styles here */
}

.tooltipContent {
    /* Add your custom styles here */
}

.tooltipArrow {
    /* Add your custom styles here */
}

You can add your custom styles in the respective sections. For example, you can change the background color, font size, color, etc. Please note that this is just an example and you might need to adjust it to fit your specific needs. You can find more information about this in the Github Issue (https://github.com/refinedev/refine/issues/4666) related to tooltip styling. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai i dont have such a component defined

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm sorry for the confusion. Refine uses Ant Design's Tooltip component under the hood, and it doesn't provide a direct way to customize the Tooltip's style from the outside. However, you can override the Ant Design's Tooltip styles globally using CSS. Ant Design uses less for styling, and you can override the variables defined in Ant Design's default less file. Here is an example of how you can override the Tooltip styles:

.ant-tooltip-inner {
  background-color: #your-color;
  color: #your-color;
  font-size: your-size;
}

.ant-tooltip-arrow-content {
  background-color: #your-color;
}

.ant-tooltip-inner {
  background-color: #your-color;
  color: #your-color;
  font-size: your-size;
}

.ant-tooltip-arrow-content {
  background-color: #your-color;
}

Please note that this will change the Tooltip styles globally in your application. If you want to change the styles for a specific Tooltip, you might need to add a custom class to that Tooltip and then use that class to change the styles. You can find more information about this in the Ant Design documentation (https://ant.design/docs/react/customize-theme). If you need more control over the Tooltip styles, you might need to create a custom Tooltip component. You can use the Popover component from Ant Design to create a custom Tooltip with your own styles. Here is an example from the Ant Design documentation (https://ant.design/components/popover/):

import { Popover } from 'antd';

const content = (
  <div>
    <p>Content</p>
    <p>Content</p>
  </div>
);

<Popover content={content} title="Title">
  <Button type="primary">Hover me</Button>
</Popover>

import { Popover } from 'antd';

const content = (
  <div>
    <p>Content</p>
    <p>Content</p>
  </div>
);

<Popover content={content} title="Title">
  <Button type="primary">Hover me</Button>
</Popover>

In this example, you can replace the content and title with your own content and styles. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Ok but where can i access this styling @kapa.ai ok but where can i access this styling

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- To access and modify the styling of Ant Design's Tooltip component, you would typically do this in your global CSS or LESS file. This file could be named something like App.css, styles.css, or main.less, and it's usually located at the root of your src directory. Here's an example of how you might override the Tooltip styles in a CSS file:

/* App.css or styles.css */

.ant-tooltip-inner {
  background-color: #your-color;
  color: #your-color;
  font-size: your-size;
}

.ant-tooltip-arrow-content {
  background-color: #your-color;
}

/* App.css or styles.css */

.ant-tooltip-inner {
  background-color: #your-color;
  color: #your-color;
  font-size: your-size;
}

.ant-tooltip-arrow-content {
  background-color: #your-color;
}

Just replace #your-color and your-size with your desired color and font size. Please note that these changes will apply to all tooltips in your application. If you want to style a specific tooltip, you would need to add a custom class to that tooltip and use that class in your CSS selector. If you're using a CSS-in-JS solution or a CSS module, you would need to follow the styling approach that's appropriate for your solution. For more information on how to customize Ant Design's styles, you can refer to the Ant Design's documentation on theme customization (https://ant.design/docs/react/customize-theme). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai Should it then just be global styling of the whole app?

kapa.ai•2mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, the changes you make in the global CSS or LESS file will apply to the whole application. This is because the styles in this file are global, meaning they are not scoped to a specific component and will affect all elements in your application that match the CSS selectors you use. For example, if you override the Tooltip styles like this:

/* App.css or styles.css */

.ant-tooltip-inner {
  background-color: #your-color;
  color: #your-color;
  font-size: your-size;
}

.ant-tooltip-arrow-content {
  background-color: #your-color;
}

/* App.css or styles.css */

.ant-tooltip-inner {
  background-color: #your-color;
  color: #your-color;
  font-size: your-size;
}

.ant-tooltip-arrow-content {
  background-color: #your-color;
}

These styles will apply to all instances of the Tooltip component in your application, not just one specific Tooltip. If you want to style a specific Tooltip, you would need to add a custom class to that Tooltip and use that class in your CSS selector. However, Refine does not provide a direct way to add a custom class to the Tooltip component used in the filters. For more control over the styles, you might need to create a custom filter component with your own Tooltip component. This way, you can control the styles of the Tooltip directly in your component. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
