How to Multiline Ruby Statements

[Nicholas Van Weerdenburg]

I want to do the following:

  :ruby

    form_remote_for :portion, Portion.new, :url=> new_portion_url, 

      :loading=> 'Form.disable("portion_form")',

      :complete=> 'Form.enable("portion_form")',

      :html=> {:id=> 'portion_form' } do |f|

    .meal_type{:style=>"float: left;"}

e.g. have my form_remote_for on multiple lines. However, I need to indent the following line (meal_type), and I'm not sure how to do it.

The other option:

    - form_remote_for :portion, Portion.new, :url=> new_portion_url, 

    -  :loading=> 'Form.disable("portion_form")',

    -  :complete=> 'Form.enable("portion_form")',

    -  :html=> {:id=> 'portion_form' } do |f|

Didn't work either due to ";" being added after each line.

Any suggestions?

Thanks,

Nick

The best way to do this is to take this big glob of code out of your view and move it into a helper. If you don't want to do that, though, use the Haml multiline syntax:

- form_remote_for :portion, Portion.new, :url=> new_portion_url, |

    :loading=> 'Form.disable("portion_form")',

    :complete=> 'Form.enable("portion_form")',

    :html=> {:id=> 'portion_form' } do |f|

Thanks. It didn't occur to me to use that with executable code.

Hmm. Doesn't work for me. Here is the code- a HAMLized example from the Agile Rails book. I've also tried with \ in front of the :'s-

- form_tag('javascript:void(0)') do

  .fake-h1 

    Listing Items

    = text_field_tag 'search', @search

    = observe_field :search, |

      :frequency => 0.5, |

      :update    => 'ajaxWrapper', |

      :before    => "Element.show('spinner')", |

      :complete  => "Element.hide('spinner')", |

      :url       => {:action=>'search', :only_path => false}, |

      :with => "'search=' + encodeURIComponent(value)"

.ajaxWrapper

  = render :partial=>'search'

Any thoughts?

Thanks,

Forgot the error:

Invalid filter name ":with => "'search=' + encodeuricomponent(value)"".

If I put \: in, I get crazy compile errors...

compile error

/Users/vanweerd/work2/innerplate/app/views/track/_item_search.haml:12: syntax error, unexpected $undefined

...mp =  observe_field :search, \:frequency => 0.5, \:update   ...

                              ^

/Users/vanweerd/work2/innerplate/app/views/track/_item_search.haml:12: syntax error, unexpected ',', expecting kEND

... \:update    => 'ajaxWrapper', \:before    => "Element.show(...

You have to put the multiline character on the last line as well.

Ah! That worked. I'll look at doc more closely next time.

Thanks,

I have to admit, I find the whole multiline syntax awkward enough that I never use it. I think maybe that was the plan ;-) Helpers FTW.

Yes multiline is still remains buggy though , Look at this failing test http://github.com/parolkar/haml/commit/f4b6c189f71fd5f12676ddabbff6ff1bd15a6605

anybody, has solution for this still?

I'm pretty sure that test passes in the master branch...

[Nicholas Van Weerdenburg]

I'm  just using it for readability for one long statement that takes a block (usually form_for). Moving this to a helper isn't really much value. Or if I did, I'd prefer after working out my logic.

The | is working well for me now. It's not bad- hardly notice it.

Thanks,
