haml

New to this tagging language, and I'm having trouble finding documentation mentioning how to work with images. An example or two would be fantastic. Btw, I did refer to this discussion , but not sure if that's what I need. Outside any kind of framework: %img(src="/images/loading.gif") The older, more verbose but flexible syntax: %img{:src => "/images/loading.gif"} If you’re using Rails, it will generate the tag itself: =image_tag "loading.gif" 来源： https://stackoverflow.com/questions/10561121/how-to-add-an-image-to-the-contents-using-haml

Depending on if a user is signed in or not, I'd like to print a different kind of %body-tag. This is how I currently do it: - if defined? @user %body(data-account="#{@user.account}") %h1 Welcome -# all my content - else %body %h1 Welcome -# all my content As you can see there's a lot of duplicated code in there. How can I eliminate this? I already tried the following: - if defined? @user %body(data-account="#{@user.account}") - else %body %h1 Welcome -# all my content Unfortunately, this doesn't work since HAML interprets it as if the %h1 and the content is part of the else-statement, which of

During refactoring it would be quite handy just to copy part of HAML template and paste it to helper's code. Currently in such cases 1) I have to rewrite that part of view from scratch 2) I have to use that verbose syntax like content_tag or haml_tag. I know that it's possible to define partials with HAML systax that will serve as helper. Though 1) as for me it's inconvinient to create a separate file for each small tiny function 2) invocation syntax for partial is quite verbose. Ideally i'd like my *_helper class to look like this: - def some_helper(*its_args) .some_class = some_ruby

I have the following piece of code %br = f.label :active, 'Status' = f.select :active, ['Active','Inactive'] Symbol :active is a boolean type var. How can i match Active => 1/True, and Inactive => 0/False , for the database adding. Sorry for the newbie question, but i can't figure it out. You can provide a pair of values for each options: first will be used as label (inner text of <option> tag), second will be used as a value attribute: = f.select :active, [['Active', true], ['Inactive', false]] It'll render something like: <select name="model[active]"> <option value="true">Active</option>

I'm making "user settings form", and stuck with HAML: = form_tag('/') - [1,2,3].each do |i| = check_box_tag "accept#{i}" = submit_tag This results in "syntax error, unexpected kENSURE, expecting $end". The working variant is = form_tag('/') - [1,2,3].each do |i| = check_box_tag "accept#{i}" = submit_tag Results in <input id="accept1" name="accept1" type="checkbox" value="1" /> <input name="commit" type="submit" value="Save changes" /> <input id="accept2" name="accept2" type="checkbox" value="1" /> <input name="commit" type="submit" value="Save changes" /> <input id="accept3" name="accept3"

I've specified gem 'haml' gem 'rdiscount' in my Gemfile and ran bundle install The relevant code is .welcome-message :markdown Welcome **#{current_user.email}** When I access the page I get Can't run Markdown filter; required 'rdiscount' or 'peg_markdown' or 'maruku' or 'bluecloth', but none were found I'm using rails 3.0.5, what am I missing? Turns out I'm an idiot. All that was needed was to restart the server. Carry on everyone. 来源： https://stackoverflow.com/questions/5424504/haml-with-markdown-claims-rdiscount-not-found
