`request` is undefined when using load hook in Smart Action form

cooki · July 28, 2021, 11:04am

Expected behavior

Accessing request.body.data.attributes.ids[0]; inside a load hook allows me to fetch that record’s id.


collection("Question", {
  actions: [
    {
      name: "Add Required Answer",
      type: "single",
      fields: [
        {
          field: "Required Answer",
          description:
            "You can only see answers which are answers to previous questions",
          reference: "Answer.id",
          type: "String",
          isRequired: true,
        },
      ],
      hooks: {
        load: async ({ fields, request }) => {
          console.log("fields: ", fields, "request: ", request);
          const questionId = request.body.data.attributes.ids[0];
          return fields;
        },
      },
    },
  ]
});

Actual behavior

the request object is undefined.

Hello @cooki,

The request parameter is not available in version 7.x.x of forest-express-sequelize.
You will need to upgrade to the V8 for accessing it.

Also do not hesitate to use the getIdsFromRequest helper as described in the documentation.

I hope it helps

thanks @Guillaume_Cisco

Hey @Guillaume_Cisco I got the following error after updating to version 8.0.5 and running my app, is this something you have seen before ?

Seems to be caused by const recordCreator = new RecordCreator(Answer); in my controllers/answers.js file,

Which is imported into server.js by

    dirname: path.join(__dirname, "controllers"),
    recursive: true,
    resolve: (Module) => app.use("/", Module),
  });

Guillaume_Cisco · July 28, 2021, 1:19pm

Yes, absolutely @cooki,

You need to update all your overidden routes as described in the documentation for upgrading to the V8 version

For example:

const { query, user } = req;

    // List helpers
    new RecordsGetter(MyModel, user, query).getAll();

@Guillaume_Cisco sweet !

cooki · July 28, 2021, 1:48pm

When developing a “Smart Action Form” and using a reference for a field, is there a way to filter the options ?

{
      name: "Add Required Answer",
      type: "single",
      fields: [
        {
          field: "required-answer",
          description:
            "You can only see answers which are answers to previous questions",
          reference: "Answer.id",
          type: "String",
          isRequired: true,
          widget: "belongsto select",
        },
      ],
      hooks: {
        load: async ({ fields, request }) => {
          const questionId = request.body.data.attributes.ids[0];
          console.log("questionId: ", questionId);
          return fields;
        },
      },
    },

I would like to limit the options available in the dropdown (coming from the Answer collection) with my custom logic.

Guillaume_Cisco · July 28, 2021, 2:44pm

Absolutely @cooki !

You can do your filtering inside the load hook function

Let me know if you succeed

cooki · July 28, 2021, 2:49pm

Hey @Guillaume_Cisco I don’t know where to start, that’s why I’m reaching out I guess. I know how to get the data I would like to display, I just don’t know how to bind it to the fields object being returned from the load hook, should I place it in a particular key ?

Currently, if I log the fields object, I can see that it holds the following data:

fields:  [
  {
    field: 'required-answer',
    description: 'You can only see answers which are answers to previous questions',
    reference: 'Answer.id',
    type: 'String',
    isRequired: true,
    position: 0,
    defaultValue: null,
    enums: null,
    widgetEdit: { name: 'belongsto dropdown', parameters: {} },
    value: null
  }
]

Guillaume_Cisco · July 28, 2021, 3:17pm

No worries @cooki,

You can transform your required-answer with an Enum type, and then in your load hook, prefill its value with filtered answers.

Would that be ok for you?

Do not hesitate if you need more help

cooki · July 28, 2021, 3:24pm

With the following code I get the following UI, can you spot something wrong in this code snippet ?

    {
      name: "Add Required Answer",
      type: "single",
      fields: [
        {
          field: "required-answer",
          description:
            "You can only see answers which are answers to previous questions",
          type: "Enum",
          enums: [],
          isRequired: true,
          widget: "belongsto select",
        },
      ],
      hooks: {
      },
    },

Guillaume_Cisco · July 28, 2021, 3:32pm

Hum, I don’t think you need the widget key, furthermore, there is nothing in your load hook function.
Did you try to fill the enums or the value key?

cooki · July 28, 2021, 3:39pm

Having the widget key messed it up, I got it to work with the following code:

    {
      name: "Add Required Answer",
      type: "single",
      fields: [
        {
          field: "required-answer",
          description:
            "You can only see answers which are answers to previous questions",
          type: "Enum",
          enums: [],
          isRequired: true,
        },
      ],
      hooks: {
        load: async ({ fields, request }) => {
          const questionId = request.body.data.attributes.ids[0];
          const requiredAnswerField = fields.find(
            (field) => field.field === "required-answer"
          );
          let answers = await Answer.findAll();
          requiredAnswerField.enums = answers;
          return fields;
        },
      },
    },

Though this gives me the following UI:

Now ideally, I would like to display a field (value), and when I hit submit, I would like send over the Id to my route.

If I do requiredAnswerField.enums = answers.map((answer) => answer.id);, then the UI shows Ids, and if I do equiredAnswerField.enums = answers.map((answer) => answer.value);, the UI would display what I want, but then would send over the value to my route and not the Id of the record.

Any Idea how I could get over this issue ?

Guillaume_Cisco · July 28, 2021, 3:43pm

Oh great!
It is working

Hum, indeed, if you need the value and the id, maybe you could also add a change hook who can fill the value of the field, with the answer selected. This way you could know the id of the selected answer.

Let me know if it helps

cooki · July 28, 2021, 4:19pm

@Guillaume_Cisco , helps a lot, is there a way to hide a field ? have it be there but not display in the UI ?

Guillaume_Cisco · July 28, 2021, 4:48pm

Hum, unfortunately I don’t think you can do this

cooki · July 28, 2021, 4:50pm

That’s ok, could you explain to me the logic of using a onChange hook to send over the ID again please ? I thought I had it understood but I cannot seem to persist data across hooks

Guillaume_Cisco · July 29, 2021, 9:13am

Hello @cooki,

After some testing, I came to the conclusion it is not possible right now by using the Enum type.
By definition, your Enum values should be unique, so you should be able to retrieve them from your route with:

‌‌req['body']['data']['attributes']['values']['answers']

Then with this value, you could retrieve the id of the object pertained to this value.

Tell me if it helps
