Bulk edits

In this course we teach you how to create admin reports with React using a query builder. Admin reporting is a broad topic, and getting started can be overwhelming.

In five modules, we cover configuration of the query builder, setting up a server, displaying data in a grid, chart, and map, as well as some more advanced uses of the query builder. It's about three hours long and comes with code samples.

The course is taught by Jake Boone, who uses React Query Builder in real, mission-critical applications for a large engineering and construction firm.

In this course, we'll be using React Query Builder to create admin reports with complex filtering, bulk editing, data grids, charts, and maps.

 component of our query builder and tailor it to the different data types.

Create a React component in a file called 

. For now, the component should simply return 

; otherwise it should return the default 

import {
  ValueEditor as DefaultValueEditor,
  ValueEditorProps,
} from "react-querybuilder";

const ValueEditor = (props: ValueEditorProps) => {
  const { operator } = props;

  if (operator === "null" || operator === "notNull") {
    return null;
  }

  return <DefaultValueEditor {...props} />;
};

export default ValueEditor;

import React, { useState } from "react";
import { QueryBuilder, formatQuery, RuleGroupType } from "react-querybuilder";
import combinators from "./combinators";
import CombinatorSelector from "./CombinatorSelector";
import fields from "./fields";
import getOperators from "./getOperators";
import translations from "./translations";
import { Language } from "./types";
import ValueEditor from "./ValueEditor";

function App() {
  const [query, setQuery] = useState<RuleGroupType>({
    id: "root",
    combinator: "and",
    rules: [],
  });
  const [language, setLanguage] = useState<Language>("en");

  return (
    <>
      <select value={language} onChange={e => setLanguage(e.target.value as Language)}>

# Custom value editors

Now we'll customize the `ValueEditor` component of our query builder and tailor it to the different data types.

## Using the default `ValueEditor`

Create a React component in a file called `ValueEditor.tsx` and use that component as your custom `ValueEditor`. For now, the component should simply return `null` if the `operator` is `null` or `notNull`; otherwise it should return the default `ValueEditor` component from `react-querybuilder`.

```typescript { actualFilename=./protected/src/ValueEditor.tsx endChar=331 endLine=17 startChar=0 startLine=1 statedFilename=client/src/ValueEditor.tsx url=https&#x3A;//gitlab.com/fullstackio/books/building-advanced-admin-reporting-in-react/module_02/lesson_02.04/protected/src/ValueEditor.tsx }
import {
  ValueEditor as DefaultValueEditor,
  ValueEditorProps,
} from "react-querybuilder";

const ValueEditor = (props: ValueEditorProps) => {
  const { operator } = props;

  if (operator === "null" || operator === "notNull") {
    return null;
  }

  return <DefaultValueEditor {...props} />;
};

export default ValueEditor;
```

```typescript { actualFilename=./protected/src/App.tsx endChar=1308 endLine=44 startChar=0 startLine=1 statedFilename=client/src/App.tsx url=https&#x3A;//gitlab.com/fullstackio/books/building-advanced-admin-reporting-in-react/module_02/lesson_02.04/protected/src/App.tsx }
import React, { useState } from "react";
import { QueryBuilder, formatQuery, RuleGroupType } from "react-querybuilder";
import combinators from "./combinators";
import CombinatorSelector from "./CombinatorSelector";
import fields from "./fields";
import getOperators from "./getOperators";
import translations from "./translations";
import { Language } from "./types";
import ValueEditor from "./ValueEditor";

function App() {
  const [query, setQuery] = useState<RuleGroupType>({
    id: "root",
    combinator: "and",
    rules: [],
  });
  const [language, setLanguage] = useState<Language>("en");

  return (
    <>
      <select value={language} onChange={e => setLanguage(e.target.value as Language)}>
        <option value="en">English</option>
        <option value="es">Spanish</option>
      </select>
      <QueryBuilder
        fields={fields}
        getOperators={getOperators}
        query={query}
        onQueryChange={(q) => setQuery(q)}
        translations={translations[language]}
        combinators={combinators[language]}
        controlElements={{
          combinatorSelector: CombinatorSelector,
          valueEditor: ValueEditor,
        }}
      />
      <pre>{formatQuery(query, "sql")}</pre>
      <pre>{formatQuery(query, "json")}</pre>
    </>
  );
}
