Re: [Rails] How to safely embed JSON object in HTML document
David,
I want to embed it in HTML so that I can just send that one HTML page to
user after log in, and no other HTTP requests are needed before the user can
start using the app.
This is because it would take several small, but slow, HTTP requests to
gather all the data that is needed to show the page. I guess I could whip up
a special API method that would return all the data in a single HTTP
roundtrip, but if I can pull off this JSOPN embedding, then I can skip even
that one extra HTTP requests for initial load. After initial load, app will
rarely be needing data from the server, and when it does, it will be using
regular API to get that data.
This is all just a performance optimization, since most of our users are on
a high latency network (mobiles), so those HTTP requests really take a
while, and this is an attempt to just skip them altogether.
Is there no easy way to embed HTML safe JSON in an HTML document, and have
it parsed by JavaScript engine at the same time?
Thanks,
Alex

Why not just call the JSON object directly from the controller instead?

Hi all,
I'm working on a Backbone.js single page app with Rails 3.1, and in an
attempt to save on HTTP requests, I want to embed initial data set in
a HTML document that is sent back to the browser after successful
login.
I was thinking I can simply convert my ruby object to JSON, then HTML
escape resulting string of JSON, and then use that as a value for
JavaScript variable. Something like this:
% tags = [{name:tag1, color:green}, {name:/scriptbI can do
something bad here/b, color:red}] %
script type=text/javascript charset=utf-8
//![CDATA[
var tags_list = %= tags.to_json %;
// ]]
/script
However, this escapes all the double quotes in that string, which
triggers a SyntaxError: Unexpected token in Chrome:
var tags_list =
[{quot;namequot;:quot;tag1quot;,quot;colorquot;:quot;greenquot;},
{quot;namequot;:quot;lt;/scriptgt;lt;bgt;I can do something bad
herelt;/bgt;quot;,quot;colorquot;:quot;redquot;}];
If I remove the Rails' default HTML escaping with %=raw tags.to_json
%, then it returns this:
var tags_list = [{name:tag1,color:green},{name:/
scriptbI can do something bad here/b,color:red}];
which, of course, breaks the HTML document with /script.
I guess what I really want is to tell to_json() method to HTML escape
keys and values inside JSON object(s), instead of it returning the
JSON string unescaped, and then having Rails escape that whole string.
I guess what I need is something like this:
var tags_list = [{name:tag1,color:green},{name:lt;/
scriptgt;lt;bgt;I can do something bad herelt;/
bgt;,color:red}];
I thought about storing JSON string in a script type=application/
json id=json_string tag, and then doing something like
$.parseJSON($(#json_string).html())
but that also has the same problem of escaping, like in the above
example.
Is there any easy (Rails) way to do that? Or am I doing it wrong to
begin with?
Cheers!

Re: [Rails] Re: How to safely embed JSON object in HTML document
I have no idea why embedded json would be considered worse than the rest of the page that is sent down. I do it all the time, usually with small items though, so I haven't have the problem you are describing. I was hoping that someone would have a suggestion of a built in method to call. I've had to do this in a helper that was constructing a complicated object, and I think this is similar to your problem: 1) enumerate through all the parts of your object that could contain dangerous data and call h() on them. 2) call raw(your_object.to_json) on the result. It's definitely not an easy, generic solution, but it gets you past this problem.

Re: [Rails] Re: How to safely embed JSON object in HTML document
The purpose of JSON is to be able to interchange the data between various systems. As you are not going to do that then why use JSON at all? Honestly if you are going to process the JSON with Javascript what dont you write your data out as Javascript data structures (which it would be converted from JSON anyway) in the page and process that? What do you gain from embedding the JSON then having to convert it into Javascript data structures over just writing the native Javascript data structures? -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] XML template render problem after upgrade to 3.0.10
Hi,
Yesterday, I upgraded from 3.0.3 to 3.0.10. I've encountered a
problem with rendering XML. Here's the situation.
The app is primarily a non-RESTful API app. Controller actions should
respond to requests with an XML response without the need to have
an .xml at the end of the route request. For my controller actions I
have written a builder (action_name.xml.builder) template and a
builder layout (all_responses.xml.builder). For all the actions in
the controller, I set the default layout to all_responses using the
controller layout class method.
Under this scenario, Rails performed as expected in version 3.0.3.
I could write the following and the correct XML with layout was
produced.
def action_name
@animal = Animal.new
render :content_type = application/xml and return
end
Rails would find the builder template under the controllers view
directory as expected. It would work as well with the following:
respond_to do |format|
format.xml{render :status = 200}
end
After upgrading to rails 3.0.10. Rendering is no longer working as
expected. Instead, I get the following error:
Missing template action_name with
{:locale=[:eng, :eng], :formats=[:html], :handlers=[:rjs, :rhtml, :erb,
:rxml, :builder]}
in view paths /Users/me/src/app_name/app/
views (ActionView::MissingTemplate)
In other words, Rails 3.0.10 no longer can find the template. It
instead appears to always be searching for the html template which
doesn't exist.
As a partial fix, I have to specify literally everything. For
example
def action_name
render :template = controller_name/
action_name.xml.builder, :status = 200, :layout =
'all_response.xml.builder' and return
end
But it only partially fixes the problem. If I go into the debugger,
when I'm in this action, and I execute manually the render line
above. I receive the correct XML response with the XML from the
all_response.xml.builder layout. However, the actual response that
Rails 3.0.10 delivers strips XML produced by the builder layout and
actually wraps my action_name.xml.builder XML with a HTML doc type and
the html tags such as html and body.
In other words, despite the fact that I specify manually all the views
and layout, it insists on producing HTML.
I'm at a lose about what's going on here. I search the Rails change
logs and couldn't find anything that seems to affect the way rendering
works.
If anyone could provide help or advice, I would greatly appreciate it.
Chad

[Rails] Nokogiri gem issues
Hello all,
I recently was pointed towards the Nokogiri gem recently to find all
html elements with a particular class, rather than attempting my own
regular expression. (Thanks John-John Tedro and Hassan Schroeder)
It works perfectly on my local machine, (Lion OS X and passenger), but
when I deployed it to my server (Centos 5.5 and passenger) Nokogiri
seems to not grab all the elements of the html file.
Here is my method:
=
def find_editable
code = Nokogiri::HTML(open(source_code(FtpAction::DOWNLOAD)))
# source_code() method returns a location of a file within the app
Rails.logger.info = code
Rails.logger.info code.inspect
elements = []
num = 0
code.css('.my-class').each do |el|
# I tried using xpath, but was not able to get it to grab elements
w/ 'class=my-class icon'
# only 'class=my-class'
attrs = []
el.attributes.each { |attr| attrs {attr[0] = attr[1].value } }
elements {:element = el.name, :attributes = attrs, :content
= el.content, :count = num+=1 }
end
Rails.logger.info elements
Rails.logger.info elements.inspect
elements
# array return of hash built above, containing:
# name (html tag)
# attributes (classes and ids and anything else)
# content actual text within element Hello World!
end
==
Below is the output from the log files. You don't really need to go
through all of the local output. The whole .html file is being parsed.
If anyone has any idea why Nokogiri is not working on my server but
would be locally, I would appreciate any help you can provide.
Also I did check that the full .html file is there on the server and
using File.open do |file| printed out the full file for me.
Thank you in advance.
Output from Rails.logger.info:

Re: [Rails] Re: How to safely embed JSON object in HTML document
Paul,
thanks for the suggestion. I was hoping there is something in Rails to do
that for me. But I guess there isn't.
Other suggestion I got, off this list, is to have JSON embedded in a
javascript string, and parsed by jQuery into an object. With proper
javascript escaping (by j method), that gets the job done. And I like that
approach better then calling h on attributes on server side, as this is more
generic IMO, since it will work for any Ruby object.
Here is the code that works:
% tags = [{name:tag1, color:green}, {name:/scriptbI can \n\ndo
something bad here/b, color:red}] %
script type=text/javascript charset=utf-8
//![CDATA[
var tags_list = $.parseJSON('%=j tags.to_json.html_safe %');
// ]]
/script
And that results in:
script type=text/javascript charset=utf-8
//![CDATA[
var tags_list =
$.parseJSON('[{\name\:\tag1\,\color\:\green\},{\name\:\\/scriptbI
can \\n\\ndo something bad here\/b\,\color\:\red\}]');
// ]]
/script
Thanks all!

The purpose of JSON is to be able to interchange the data between
various systems. As you are not going to do that then why use JSON at
all?
Honestly if you are going to process the JSON with Javascript what
dont you write your data out as Javascript data structures (which it
would be converted from JSON anyway) in the page and process that?
What do you gain from embedding the JSON then having to convert it
into Javascript data structures over just writing the native
Javascript data structures?

Re: [Rails] call a controller action from another controller
just create my_module.rb in lib/
module MyModule
def my_method
…
end
end
and in your controller just
class MyController ApplicationController
include MyModule
def search
my_method(params)
end
end
just check whether your module is loaded or add require to your

}
graph.render :to = pie_test.svg
graph.render :width = 300, :height = 200,
:to = pie_test.png, :as = 'png'
and i get an error in
graph.render :width = 300, :height = 200,
:to = pie_test.png, :as = 'png'
no such file to load -- RMagick
i haven't found in any place something that says that scruffy needs
rmagick to work... it's really necesary to install it for render the

I only ask because i'm having problems to install rmagick, it says that
it failed building the native extencion even if i have installed the

If you give up on installing a newer version of libxml (I've tried it in
the past and found it impossible), you can use xpath() to do what you
want:
!DOCTYPE html
html
head
titleTest/title
/head
body
h1 class='editor highlight'Hello world/h1
div class=editor_fruit redApple/div
div class=article_editor

f = File.open('2html.htm')
doc = Nokogiri::HTML(f)
results = doc.xpath(//*[contains(concat(' ', @class, ' '), ' editor

p [
el.attributes['class'].value,
el.children[0].text

end
--output:--
[editor highlight, Hello world]
[hide editor, Papillon]

Re: [Rails] strings issue
full patch of archives is? if under rails root, then change code to
string = Rails.root.to_s+'/archives/results/'+r
or write down full path to archives directory

Archives-2011-08-26-09-56-00-UTC.xml
It's not only possible, that is exactly what is at the end of r. When
you are having such a problem, it is easier to see what the string
actually contains by doing one of the following:
1) puts --#{some_var}---
2) p r
which is the same as:
puts r.inspect
Here is an example:
str = hello
world
p str
--output:--
hello\nworld
And of course the newline makes a difference in the file name. You can
test that yourself:
some_file = html.htm
File.open(some_file) do |f|
puts f.read
end
Once you get that to work with a file on your file system, try adding a
\n to the end.
