Custom methods ?

[mtancoigne]

Hi !
There is an issue with random.number, we can't set a minimum/maximum value:

• field: {{random.number}} - gives a random number
• field: {{random.number(x)}} - gives a random value, x being the max
• faker.random.number({min:x, max:y}) - Gives a randome value between x and y
• but field: {{random.number({min:x, max:y})}} returns NaN

So I was wondering of there is a possibility to add custom generators to Sails-hook-sanseed, or if it is planned.

Thanks for your work.

Edit The question has been developped below.

Well, I speaked a bit too quickly. Sorry for that.

Sorry, but
what happened?

Sorry :)
I was implementing the seeds and had issues with faker : it seems impossible to use {{random.number}} with a min and a max value (I wanted to use it to generate random ids for models relations). It only works with the max value ({{random.number(max)}}). So my question was about implementing the possibility to pass a method or something, to replace the fakers one.

That would allow us to create some custom generators too...

But for now, i don't really know the state of this issue, as i'm really, really tired...

Whatever, do you think it's possible to implement something like this in the future ?

Hi!

Here, i'm back with a more constructive explanation.

For example, I have this seed:

       question: {
        faker: {
          format: {
            level: "{{random.number(5)}}", // level is valid in a range of 1-5, so it won't work as zeros are generated
            // level: `${getRandomInt(1, 5)}`, // won't work too, as only evaluated once
            question: "{{lorem.words(5)}}?",
            answer: "{{random.number(3)}}",
            answers: [  // this won't work either, the array is created with "{{lorem.words(10).}}" strings
              "{{lorem.words(10).}}",
              "{{lorem.words(10).}}",
              "{{lorem.words(10).}}",
              "{{lorem.words(10).}}",
            ],
          },
          locale: "fr",
          quantity: seedConf.pledges,
          oneTo: {
            question_category: {
              id: getRandomInt(1, seedConf.questionCategories), // This is a custom method wich runs fine as not a faker input
            }
          },
          manyTo: {},

        },
        migrate: "drop"
      },

The idea is to be able to pass custom data generators methods to to properties, maybe a callback or something...

fakeField: function() {return specific_generator(some, custom, params)},

Then in the hook, you may test if the field is a string or a method and use faker or call the method accordingly...

What do you think ?
