I have a tooltip that use this html attribute "original-title".
I have tryed this:
content_tag(:span, '', :class => options[:pinfo_class], :original-title => options[:pinfo])
But it gives a error in view.
Then I have used this which works, but not with the tooltip.
content_tag(:span, '', :class => options[:pinfo_class], :original_title => options[:pinfo])
How do I force rails to use the :original-title ?
You can use a string as a hash key, like 'original-title' => options[:pinfo]. Should work.
Also, most strings can be converted to symbols via 'some-string'.to_sym method, or even defined as :'some-string'.

How can I add hash map element with a key that contains "-"?
Like this:
<%= button_to_function 'Cancel','cancelRemove("cancelEmail")', :data-dismiss=>'modal', :class=>'btn' %>
I get an error:
undefined local variable or method 'dismiss' for #<ActionView::Base:0x3482fed>
While :'data-dismiss' works, with data attributes you can also do
:data => { :dismiss => 'modal' }
Additional data-prefixed html attributes can be included in the same hash. So for example on another link you might do:
:data => { :remote => true, :method => 'delete' }
which would add to the link the html attributes data-remote="true" data-method="delete".
While the hash syntax is less compact for a single attribute, it's nice when you've got more than one html5 data attribute. And it's arguably a bit more rails-ish.
Just rename it to:
<%= button_to_function 'Cancel','cancelRemove("cancelEmail")', :'data-dismiss'=>'modal', :class=>'btn' %>
I currently have a simple method in my application_helper.rb file, which is designed to add a link that will add some a new field to a form when clicked. It looks like:
def link_to_add_fields(type, object_form_builder)
link_to type, "#", "data-partial" => h(render(:partial => type + '/form',
:locals => {type.singularize.to_sym => object_form_builder,
:form_actions_visible => false})),
:class => 'add_fields'
end
I'm having a problem with this code, namely that the partial that should be getting added to the data-partial html attribute is being escaped (presumably by quotes somewhere in the rendered html). I was of the understanding that h() should prevent this, but it doesn't seem to be doing so. Can anyone suggest how to escape this?
EDIT: I tried using the html_safe method as described below, but to no avail. I have managed to get it to escape by doing:
"data-partial" => "'" + render(:partial => type + '/form', :locals => {type.singularize.to_sym => object_form_builder, :form_actions_visible => false}) + "'"
but i'm not sure how safe this is?
EDIT 2: escaping using single quotes is no good - although it escapes the html, it outputs the quotes when the partial is rendered, which is not desirable. Still looking for any ideas on how to escape the html successfully when rendering the partial.
Try an .html_safe method
def link_to_add_fields(type, object_form_builder)
link_to type, "#", "data-partial" => h(render(:partial => type + '/form',
:locals => {type.singularize.to_sym => object_form_builder,
:form_actions_visible => false})).html_safe,
:class => 'add_fields'
end
In my Rails app, I need to set a value for a custom data-* attribute on an anchor tag. However, hashes can't have hyphens if I'm not mistaken. I essentially want to do this:
<%= link_to 'Example', example_path, :class => 'something', :data-id => '15' %>
:data-id is not valid, however. What can I do to work around this?
IIRC, for such purposes hashes and strings are equivalent, so you can use "data-id" instead of :data-id. Never checked for this particular method, though, so no guarantees.
I think in Rails 3 you can do
link_to "Click Here", root_path, :data => { :id => #model.id }
for all data attributes.
i am trying to call a remote method to update page content via ajax/js.
either i am too tired already or haml is not parsing the following code correctly to send the value of the query field via prototype. any ideas?
- form_remote_tag(:url => {:controller => "search", :action => "line"},:with => "'query=' + $('query').value" ) do
%input{:type => 'text', :id => 'query'}
%input{:type => 'submit', :value => 'Search'}
thanks a lot!

Have you tried a
= form_remote_tag
instead of
- form_remote_tag
I'm new to HAML myself but I was under the impression that you'll need the form tag to be actually generated not just executed...
Try passing the :with as part of the options hash.
- form_remote_tag({ :url => {:controller => "search", :action => "line"}, :with => "'query=' + $('query').value" }) do
If that doesn't work, debug the problem: Look at the generated html. Is the text field with id query the only element in the page with that id? Is the js code correct? Use the Firebug console to ensure $('query').value returns whatever you've entered into the text field.
Still stuck? Add your generated html into your question so we can better help.
EDIT: Your query input tag does not have a name attribute. Without a name, the javascript helper code skips that field when serializing the form fields...also, you do not need the :with code.
%input{:type => 'text', :id => 'query', :name => 'query'}
I am working on a rails project. Using the tag observe_field, I am taking text typed into a text area, processing it in a control, and displaying the result in a div (very similar to the preview in stack overflow). Everything works fine until I type certain special chars.
? => causes the variable not to be found in the params object
(pound) => causes an invalid authenticity error
% => stops the div from being updated
& => every thing after the & is no longer passed into the variable on the server.
Is there a way to solve this?
--- code sample ---
this is the view. ( 'postbody' is a text area)
<%= observe_field 'postbody',
:update => 'preview',
:url => {:controller => 'blog', :action => 'textile_to_html'},
:frequency => 0.5,
:with => 'postbody' -%>
this is the controller that is called
def textile_to_html
text = params['postbody']
if text == nil then
#textile_to_html = '<br/>never set'
else
r = RedCloth.new text
#textile_to_html = r.to_html
end
render :layout => false
end
and this is the javascript that is created:
new Form.Element.Observer('postbody', 0.5, function(element, value) {new Ajax.Updater('preview', '/blog/textile_to_html', {asynchronous:true, evalScripts:true, parameters:'postbody=' + value + '&authenticity_token=' + encodeURIComponent('22f7ee12eac9efd418caa0fe76ae9e862025ef97')})})
This is an escaping issue (as stated by others).
You'll want to change your observe_field :with statement to something like:
:with => "'postbody=' + encodeURIComponent(value)"
Then in your controller:
def textile_to_html
text = URI.unescape(params['postbody'])
...
Can you provide a code sample?
More likely than not you'll just need to escape your HTML entities using encodeuri or something like that.
What does the generated Javascript look like?
Sounds (at first glance) like it's not being escaped.
