First, with React Router:

React Routerimport { Link } from "react-router-dom";

const Dashboard = ({ match, history }) => {
  return (
    <div>
      <div>
        <Link to={`${match.url}/invoices`}>Invoices</Link>
        <Link to={`${match.url}/team`}>Team</Link>
      </div>

      <!-- content -->

      <div>
        <Link to="/">Home</Link>
        <Link to="/about">About</Link>
        <Link to="/support">Support</Link>
        <a onClick={history.goBack}>Go Back</a>
      </div>
    </div>
  );
}
First, with React Router:

React Routerimport { Link } from "react-router-dom";

const Dashboard = ({ match, history }) => {
  return (
    <div>
      <div>
        <Link to={`${match.url}/invoices`}>Invoices</Link>
        <Link to={`${match.url}/team`}>Team</Link>
      </div>

      <!-- content -->

      <div>
        <Link to="/">Home</Link>
        <Link to="/about">About</Link>
        <Link to="/support">Support</Link>
        <a onClick={history.goBack}>Go Back</a>
      </div>
    </div>
  );
}
Here’s the same example with Reach Router:

Reach Router<Report
  path="dashboard/:reportId"  // static routes work too :)
  salesData={this.state.salesData}
/>

const Report = (props) => {
  return (
    <h1>
      {props.reportId}
      and
      {props.salesData}
    </h1>
  )
}
Here’s the same setup using Reach Router:

Reach Routerimport React from "react";
import { Router } from "@reach/router";

const App = () => {
  return (
    <div>
      <h1>Global Party Supplies, Inc</h1>
      <Router>                           //  PATHS
        <Home path="/"/>                 //  "/"
        <About path="about"/>            //  "/about"
        <Support path="support"/>        //  "/support"
        <Dashboard path="dashboard">     //  "/dashboard"
          <Report path=":reportId"/>     //  "/dashboard/:reportId"
          <Invoices path="invoices"/>    //  "/dashboard/invoices"
          <Team path="team"/>            //  "/dashboard/team"
        </Dashboard>
      </Router>
    </div>
  );
}
First, a setup using React Router:

React Routerimport React from "react";
import { BrowserRouter as Router, Route } from "react-router-dom";

const App = () => {
  return (
    <Router>
      <div>
        <h1>Global Party Supplies, Inc</h1>                          //  PATHS
        <Route component={Home}       path="/"            exact/>    //  "/"
        <Route component={About}      path="/about"/>                //  "/about"
        <Route component={Support}    path="/support"/>              //  "/support"
        <Route component={Dashboard}  path="/dashboard"/>            //  "/dashboard"
        <Route component={Invoices}   path="/dashboard/invoices"/>   //  "/dashboard/invoices"
        <Route component={Team}       path="/dashboard/team"/>       //  "/dashboard/team"
        <Route component={Report}     path="/dashboard/:reportId"/>  //  "/dashboard/:reportId"
      </div>
    </Router>
  );
}
First, reportId and salesData with React Router:

React Router<Route
  path="/dashboard/:reportId"
  render={(props) => {
    return <Report {...props} salesData={true} />
  }}
/>

const Report = ({ props, match }) => {
  return (
    <h1>
      {match.params.reportId}  // "match" is from react-router
      and
      {props.salesData}
    </h1>
  )
}

The FileComparer class shown here demonstrates how to use a custom comparer class together with the Standard Query Operators. The class is not intended for use in real-world scenarios. It just uses the name and length in bytes of each file to determine whether the contents of each folder are identical or not. In a real-world scenario, you should modify this comparer to perform a more rigorous equality check.

namespace QueryCompareTwoDirs  
{  
    class CompareDirs  
    {  
  
        static void Main(string[] args)  
        {  
  
            // Create two identical or different temporary folders
            // on a local drive and change these file paths.  
            string pathA = @"C:\TestDir";  
            string pathB = @"C:\TestDir2";  
  
            System.IO.DirectoryInfo dir1 = new System.IO.DirectoryInfo(pathA);  
            System.IO.DirectoryInfo dir2 = new System.IO.DirectoryInfo(pathB);  
  
            // Take a snapshot of the file system.  
            IEnumerable<System.IO.FileInfo> list1 = dir1.GetFiles("*.*", System.IO.SearchOption.AllDirectories);  
            IEnumerable<System.IO.FileInfo> list2 = dir2.GetFiles("*.*", System.IO.SearchOption.AllDirectories);  
  
            //A custom file comparer defined below  
            FileCompare myFileCompare = new FileCompare();  
  
            // This query determines whether the two folders contain  
            // identical file lists, based on the custom file comparer  
            // that is defined in the FileCompare class.  
            // The query executes immediately because it returns a bool.  
            bool areIdentical = list1.SequenceEqual(list2, myFileCompare);  
  
            if (areIdentical == true)  
            {  
                Console.WriteLine("the two folders are the same");  
            }  
            else  
            {  
                Console.WriteLine("The two folders are not the same");  
            }  
  
            // Find the common files. It produces a sequence and doesn't
            // execute until the foreach statement.  
            var queryCommonFiles = list1.Intersect(list2, myFileCompare);  
  
            if (queryCommonFiles.Any())  
            {  
                Console.WriteLine("The following files are in both folders:");  
                foreach (var v in queryCommonFiles)  
                {  
                    Console.WriteLine(v.FullName); //shows which items end up in result list  
                }  
            }  
            else  
            {  
                Console.WriteLine("There are no common files in the two folders.");  
            }  
  
            // Find the set difference between the two folders.  
            // For this example we only check one way.  
            var queryList1Only = (from file in list1  
                                  select file).Except(list2, myFileCompare);  
  
            Console.WriteLine("The following files are in list1 but not list2:");  
            foreach (var v in queryList1Only)  
            {  
                Console.WriteLine(v.FullName);  
            }  
  
            // Keep the console window open in debug mode.  
            Console.WriteLine("Press any key to exit.");  
            Console.ReadKey();  
        }  
    }  
  
    // This implementation defines a very simple comparison  
    // between two FileInfo objects. It only compares the name  
    // of the files being compared and their length in bytes.  
    class FileCompare : System.Collections.Generic.IEqualityComparer<System.IO.FileInfo>  
    {  
        public FileCompare() { }  
  
        public bool Equals(System.IO.FileInfo f1, System.IO.FileInfo f2)  
        {  
            return (f1.Name == f2.Name &&  
                    f1.Length == f2.Length);  
        }  
  
        // Return a hash that reflects the comparison criteria. According to the
        // rules for IEqualityComparer<T>, if Equals is true, then the hash codes must  
        // also be equal. Because equality as defined here is a simple value equality, not  
        // reference identity, it is possible that two or more objects will produce the same  
        // hash code.  
        public int GetHashCode(System.IO.FileInfo fi)  
        {  
            string s = $"{fi.Name}{fi.Length}";
            return s.GetHashCode();  
        }  
    }  
}

Set the index and group by the columns you want to compare. For each group get the diff() and dropna() (this is to eliminate the same rows of the group) and reset_index to get all the columns. Now this will give you a dataframe with the rows that are matching and qty with the diff()


df2 = df.set_index(compare_cols).groupby(compare_cols)['qty'].diff().dropna().reset_index()
df2['general'] = 'sub_output'
print(df2)

assuming your text examples are in files f1.txt and f2.txt,



kettle$ ./compare.pl f1.txt f2.txt

Deleted:
111,Name 111,ATT X
Added:
Changed:
123,Name 123,ATT X||123,Name 123,ATT CHANGED

You need to compare it with a JSONB array:

But this depends on the order of the elements in the array. If you want to test all keys regardless of the order, the ?& operator might be better:

That would however also return rows that contain additional elements in the array. If you need to match all elements exactly regardless of the order you could use the @> operator twice:


select *
from product
where contact -> 'country' = '["USA","UK"]'::jsonb;


where contact -> 'country' ?& array['UK','USA']


where contact -> 'country' @> '["USA","UK"]'::jsonb
  and contact -> 'country' <@ '["USA","UK"]'::jsonb
