JQ remove objects based on key value-CodePudding

I'm trying to delete objects from a JSON payload if they have a key with a specific value

{
  "data": [
    {
      "account": "12xUoMKwf12ABjNx4VCvYcNkX79gW1kzz2JnBLxkFbjswRczRvM",
      "gateway": "113kQU96zqePySTahB7PEde9ZpoWK76DYK1f57wyhjhXCBoAu88",
      "hash": "DTU1GGfR0eU15hv6KiV_bg6FOJXfUWz4TjIq1H7TGy4",
      "timestamp": "2020-08-28T01:29:46.000000Z"
    },
    {
      "account": "12xUoMKwf12ABjNx4VCvYcNkX79gW1kzz2JnBLxkFbjswRczRvM",
      "gateway": "113kQU96zqePySTahB7PEde9ZpoWK76DYK1f57wyhjhXCBoAu88",
      "hash": "l3EQR6AJ6R1qE1meHyafDnNF8vJ-X-rH1pujxQRTds4",
      "timestamp": "2020-08-28T00:50:44.000000Z"
    },
    {
      "account": "12xUoMKwf12ABjNx4VCvYcNkX79gW1kzz2JnBLxkFbjswRczRvM",
      "gateway": "113kQU96zqePySTahB7PEde9ZpoWK76DYK1f57wyhjhXCBoAu88",
      "hash": "5fQJY9MprH9b3IstVU1SdfBteUWoF_sdsVuiARPBtTY",
      "timestamp": "2020-08-27T19:01:48.000000Z"
    },
    {
      "account": "12xUoMKwf12ABjNx4VCvYcNkX79gW1kzz2JnBLxkFbjswRczRvM",
      "gateway": "113kQU96zqePySTahB7PEde9ZpoWK76DYK1f57wyhjhXCBoAu88",
      "hash": "0M0fudEmzW9dmAsO3dcWT286tTL6wTX9sllXtsyz-0Q",
      "timestamp": "2020-08-27T18:15:17.000000Z"
    }
  ]
}

I want to delete the entire object where .data[].hash == 0M0fudEmzW9dmAsO3dcWT286tTL6wTX9sllXtsyz-0Q to produce:

{
  "data": [
    {
      "account": "12xUoMKwf12ABjNx4VCvYcNkX79gW1kzz2JnBLxkFbjswRczRvM",
      "gateway": "113kQU96zqePySTahB7PEde9ZpoWK76DYK1f57wyhjhXCBoAu88",
      "hash": "DTU1GGfR0eU15hv6KiV_bg6FOJXfUWz4TjIq1H7TGy4",
      "timestamp": "2020-08-28T01:29:46.000000Z"
    },
    {
      "account": "12xUoMKwf12ABjNx4VCvYcNkX79gW1kzz2JnBLxkFbjswRczRvM",
      "gateway": "113kQU96zqePySTahB7PEde9ZpoWK76DYK1f57wyhjhXCBoAu88",
      "hash": "l3EQR6AJ6R1qE1meHyafDnNF8vJ-X-rH1pujxQRTds4",
      "timestamp": "2020-08-28T00:50:44.000000Z"
    },
    {
      "account": "12xUoMKwf12ABjNx4VCvYcNkX79gW1kzz2JnBLxkFbjswRczRvM",
      "gateway": "113kQU96zqePySTahB7PEde9ZpoWK76DYK1f57wyhjhXCBoAu88",
      "hash": "5fQJY9MprH9b3IstVU1SdfBteUWoF_sdsVuiARPBtTY",
      "timestamp": "2020-08-27T19:01:48.000000Z"
    }
  ]
}

Is this possible to do? The size of the object can vary and have many different keys in the payload. The one thing that is constant and unique is the .data[].hash key

Thanks

You can use del along with select function such as

jq 'del(.data[] | select(.hash == "0M0fudEmzW9dmAsO3dcWT286tTL6wTX9sllXtsyz-0Q"))'

If the goal really is:

to delete objects from a JSON payload if they have a key with a specific value

where the key is hash, then you could use walk like so:

walk(if type=="object" and
          .hash == "0M0fudEmzW9dmAsO3dcWT286tTL6wTX9sllXtsyz-0Q"
     then empty else . end)

Notice that there is no reference to .data in this program.
