I need to insert a merge-tag in a text. For example I have the merge tag |NAME|, so, I would like to replace |NAME| in any part of a paragraph. For example if |NAME| = Carlos
Lorep ipsum |NAME| dorel pored = Lorep ipsum Carlos dorel pored
or
|NAME| Lorep ipsum dorel pored = Carlos Lorep ipsum dorel pored
How can I do that with rails?
Are there some plugin in rails for that?
Thanks in advance
UPDATE
Sorry, I think I explained bad. This not have to be hard coded. The user has a textbox where he can decide where to put the merge-tag to appear in any place of the text entered.
in controller:
#name = 'Carlos'
in view:
Lorep ipsum <%= #name %> dorel pored

Here is my simple rails 3 code :
<%= link_to "link", gateway_index_url(developer:#item.developer.api_key, tracker:"email", url:#product.url) %>
And the result is :
<a href="/gateway?developer=abcde&tracker=email&url=http%3A%2F%2Fwww.bla.fr%2FproductA" >link</a>
The problem is that & are rewritten in &. I can't figure how to prevent escaping, as :escape => false doesn't exist in Rails 3
Update: So here's the source
def link_to(*args, &block)
if block_given?
options = args.first || {}
html_options = args.second
link_to(capture(&block), options, html_options)
else
name = args[0]
options = args[1] || {}
html_options = args[2]
html_options = convert_options_to_data_attributes(options, html_options)
url = url_for(options)
href = html_options['href']
tag_options = tag_options(html_options)
href_attr = "href=\"#{ERB::Util.html_escape(url)}\"" unless href
"<a #{href_attr}#{tag_options}>#{ERB::Util.html_escape(name || url)}</a>".html_safe
end
end
As we can see, from the source, this behavior is by design.
You can try one of two solutions, I haven't tried them but they should work
1.) Try placing the call to gateway inside of a call to #raw:
<%= link_to "link", raw(gateway_index_url(developer: #item.developer.api_key, tracker:"email", url:#product.url)) %>
That may solve your specific problem, an the second approach, while a bit more brute-force should also work...
2.) If you want to convert it (the whole href) back you can... use CGI::unescape_html:
<%= CGI::unescape_html(link_to "link", gateway_index_url(developer: #item.developer.api_key, tracker:"email", url:#product.url)) %>
Good luck, hopefully this helps.
Update 2: Fixed call to cgi unescape, was using "." when it should be "::" and formatting fix. Forgot to indent example for #1
Rory O'Kane is spot on. The answer to "Why are ampersands escaped when generating url with link_to?" is that is the correct way to separate params in a url.
Is there a problem with the url the way it is?
If so, could you elaborate on the problem?
You may be able to prevent escaping the url by using raw on the entire url like so:
<%= link_to "link", raw(gateway_index_url(developer:#item.developer.api_key, tracker:"email", url:#product.url)) %>
I'd like to include a rails object in my keywords as well as straight text but the code is clearly not the right way to do it...how can I do this?
set_meta_tags :keywords => %w[keyword1 keyword2 #{params[:hospital]}]
You might want to have a look at two plug-ins for including rails object in meta tags:
Meta Magic: https://github.com/lassebunk/metamagic
Head Liner: https://github.com/mokolabs/headliner
Edit: For Meta tag gem
What I usually do is write a meta helper that I simply stick in my ApplicationHelper, that looks like this:
def meta(field = nil, list = [])
field = field.to_s
#meta ||= {
'robots' => ['all'],
'copyright' => ['My Copyright'],
'content-language' => ['en'],
'title' => [],
'keywords' => []
}
if field.present?
#meta[field] ||= []
case list.class
when Array then
#meta[field] += list
when String then
#meta[field] += [list]
else
#meta[field] += [list]
end
case field
when 'description' then
content = truncate(strip_tags(h(#meta[field].join(', '))), :length => 255)
else
content = #meta[field].join(', ')
end
return raw(%(<meta #{att}="#{h(field)}" content="#{h(content)}"/>))
else
tags = ''
#meta.each do |field, list|
tags += meta(field)+"\n"
end
return tags.rstrip
end
end
You can simply set meta tags in your views, by adding a call to meta() in it. So in an articles/show.html.erb you might add this to the top of your view:
<% meta(:title, #article.title) %>
And in your layouts, you add it without any parameters, so it'll spit out the meta tags.
<%= meta %>
Or have it output an individual tag:
<%= meta(:title) %>
I bet you there's more elegant solutions, though.
But if you were looking for something already implemented in Rails you're out of luck.
Thanks.
Try this in your view as it worked for me (using meta-tags gem):
<% keywords [[#modelname.keyword1], [#modelname.keyword2]] %>
and you cad additional keywords in text format by adding them within the ruby in the following format ['keyword3']
I am using a helper method from ryan bates railscasts on ancestry to display nested messages(code below works perfectly).
def nested_messages(messages)
messages.map do |message, sub_messages|
render(message) + content_tag(:div, nested_messages(sub_messages), :class => "nested_messages")
end.join.html_safe
end
The above bit of code nests the individual divs in a tree like structure. I would like to make this into an unordered list, so what i have done is this:
def nested_messages(messages)
messages.map do |message, sub_messages|
content_tag(:ul, :class => "") do
render(message)
content_tag(:li, :class => "nested_messages") do
nested_messages(sub_messages)
end
end
end.join.html_safe
end
The generated html looks fine, however the list items contain no values. Am i doing something wrong?
UPDATE
I would like the generated html to look like this:
<ul>
<li>Main Message</li> <!-- first message -->
<li>
<b>Message 1</b>
<ul>
<li>Message 1 subchild 1</li>
<li>Message 1 subchild 2</li>
</ul>
</li>
</ul>
UPDATE 2
I have changed it to this and it works, thanks to Dave:
def nested_messages(messages)
messages.map do |message, sub_messages|
#render(message) + content_tag(:div, sub_messages, :class => "nested_messages")
content_tag(:ul, :class => "") do
content_tag(:li, :class => "nested_messages") do
render(message) + nested_messages(sub_messages)
end
end
end.join.html_safe
end
You create a ul tag, then render the message. If you do that, what will your HTML look like?
Things inside a ul should be in a nested li: you just render the message.
You need to put it in an li tag so the unordered list has valid content.
I want to print text to HTML. I'm using simple_format, however everything seems to be right except that what is inside "< >" is not printed.
Thanks.
You can pass in a :sanitize option to tell it not to sanitize your tags:
<%= simple_text(my_string, nil, :sanitize => false) %>
I have this partial that renders a line containing three peaces of data contained in a span, and between the spans there is a hyphen. Since the hyphen is a haml keyword (or whatever you call that) you can't just put it between the spans, or haml would go looking for a function or variable. So I've got this
%p
%span{ :class => 'client'}= "#{ won_or_lost['object']['deal']['client'] }"
= "-"
%span{ :class => 'value'}= "#{ won_or_lost['object']['deal']['value'] }"
= "- Thanks to"
%span{ :class => 'owner'}= "#{ won_or_lost['object']['deal']['owner'] }
You probably agree with me that
= "-"
is rather ugly. It's not a real problem, but is there a clean way to do this?
%p
%span.client= won_or_lost['object']['deal']['client']
\-
%span.value= won_or_lost['object']['deal']['value']
\- Thanks to
%span.owner= won_or_lost['object']['deal']['owner']
http://haml-lang.com/docs/yardoc/file.HAML_REFERENCE.html#escaping_
I sometimes prefer to use an Em-dash, which I think looks better typographically:
%p
%span.client= won_or_lost['object']['deal']['client']
—
%span.value= won_or_lost['object']['deal']['value']
— Thanks to
%span.owner= won_or_lost['object']['deal']['owner']
