Jmespath configurando a expr jmespath dinamicamente

Question

Estou usando o jmespath da seguinte maneira

data = {
    "value": [
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing2",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing3",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
    ]
}

E definindo a expr jmespath dinamicamente como:

report= 'SalesMarketing3'

jmespath.search(f"'value[?name == {report}]'", data)

Em vez de obter o dicionário correspondente a "SalesMarketing3", estou obtendo a saída da seguinte forma: Estou faltando alguma coisa?

'valor [? name == SalesMarketing3]'

Qualquer ajuda é muito apreciada.

Answer 1

Seu problema está vindo do fato de que você tem que pesquisar na string ou literal de string bruta SalesMarketing3 .
Em JMESPath:

• Uma string é delimitada por aspas simples: 'SalesMarketing3'
• Um literal de string bruto é delimitado por crases: `SalesMarketing3`

Dado example.py :

import jmespath

data = {
    "value": [
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing2",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
        {
            "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
            "id": "5b218778-e7a5-4d73-8187-f10824047715",
            "name": "SalesMarketing3",
            "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
            "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48",
        },
    ]
}
report = 'SalesMarketing3'

print(jmespath.search(f"value[?name == `{report}`]", data))
## Another equivalent is:
# print(jmespath.search(f"value[?name == '{report}']", data))

Isso dá a saída esperada:

[
  {
    "datasetId": "cfafbeb1-8037-4d0c-896e-a46fb27ff229",
    "id": "5b218778-e7a5-4d73-8187-f10824047715",
    "name": "SalesMarketing3",
    "webUrl": "https://app.powerbi.com/groups/f089354e-8366-4e18-aea3-4cb4a3a50b48/reports/5b218778-e7a5-4d73-8187-f10824047715",
    "embedUrl": "https://app.powerbi.com/reportEmbed?reportId=5b218778-e7a5-4d73-8187-f10824047715&groupId=f089354e-8366-4e18-aea3-4cb4a3a50b48"
  }
