How to pass form content to Rest Service

[Krystian]

Hi,

In my page I have form, which has dynamically changed number of lines. I'd like to pass content of this form to Rest service as a JSON. How to do that in Lift?

Thanks,

Krystian

Look into RestHelper—there are many examples both on the list and online. It will let you set up a REST

endpoint that will accept JSON that is automatically parsed by lift-json, at which point you can do whatever

you need with it.

Thanks,

Thanks,
But I need help with a way to pass content of form, to with writing rest helper.
In my snippet I have a form where number of rows might change (I'm just adding new rows by AppendHtml).
What I want to do is to somehow convert content of form to JSON and pass it to REST.

you can do that with your favorite javascript library, jquery, etc. But maybe there is a better way to handle all this without using a rest endpoint.

maybe this post will help you

https://fmpwizard.telegr.am/blog/adding-fields-dynamically-lift

it adds fields to a page and send them all to the server, there is an example application with full code so you can play around with it and adjust it to fit your use case.

Hope it helps.

Ok, I got it. I'll play with hints from your article as well.

Many thanks, Krystian

Rockin'. To address the core original question of “how do I take this form and turn it into JSON”—that is largely a client-side problem,

and while Lift provides helpers for various permutations of that, I don't think it makes sense for us to provide out-of-the-box helpers for

the particular use case you're describing (partly because you can handle it using strategies like Diego's).

Once you have your RestHelper set up, you can on the client always use jQuery to do something like:

  var formData = $('form').serializeArray()

  $.post('/path/to/rest/helper', formData, ...)

Another option is that you can just set your form's action to your RestHelper endpoint, and read the field values using S.param.

So, there are many strategies that lurk in the background here :)

Thanks,

Antonio
