Form_for helper in Slim template

sakuro · April 14, 2017, 1:16pm

As a study, I am rewriting code examples from Getting Started document with the Slim template engine, but the form_for part become so ugly. Rush of backslashes!

Are there any better way to write forms using Slim in Hanami templates?

github.com

sakuro/bookshelf/blob/master/apps/web/templates/books/new.html.slim

h2 Add book

- unless params.valid?
  .errors
    h3 There was a problem with your submission
    ul
      - params.error_messages.each do |message|
        li = message
= form_for :book,  routes.books_path do \
  div class: 'input' do \
    label :title; \
    text_field :title \
  end; \
  div class: 'input' do \
    label :author; \
    text_field :author \
  end; \
  div class: 'controls' do \
    submit 'Create Book' \
  end \

@sakuro Hi, does slim is able to “capture” blocks?

sakuro · April 14, 2017, 4:25pm

I am not sure if it can but README has a section mentioning capturing.

Thanks for pointing up. That can be a good input to work on.

I haven’t dig the code but “capturing” can help to improve Slim support. Can you please create a ticket on hanami/view? Thanks.

I created #122.
