Here's the code in my haml file:
= render :partial => _paragraph,
:locals => {:content => "It is hot. But something's definitely up."}
How can I make the last sentence bold?
You can add the tags in your string, then insert them as raw text in your paragraph partial
= render :partial => _paragraph, :locals => {:content => "It's one thing to notice an uptick in appetite if you've been training hard at the gym, or if you're pregnant or PMS-ing. <b>But when you always feel like a bottomless pit for no obvious reason, then something's definitely up.</b>"}
And in _paragraph
= raw content

This is my current working code:
= auto_link(strip_tags(simple_format(truncate(user.notes, :length => 150, :separator => " ", :escape => false))),html: { target: '_blank' })
I'm using rich text editor, and I want to whitelist href or a tags, but the sanitize method doesn't work for me, only strip_tags removes the HTML tags that I want to.
How do I white list using strip_tags?
Maybe you should try sanitize GEM.
For rich editor, I suggest sanitize when you save the content in to DB, not when you are going to display the content. It much more safe.
This is how I use in my project, in before_save, sanitize value.
safe_value = Sanitize.fragment(value,
:elements => %w{a b br em i li ol p strong u ul},
:attributes => {'a' => ['href'], 'p' => ['style'], 'ol' => ['style'], 'ul' => ['style'], 'li' => ['style']},
:add_attributes => {'a' => {'rel' => 'nofollow'}}, # nofollow for SEO
:protocols => {'a' => {'href' => ['http', 'https']}},
:css => {:properties => ['text-align', 'margin-left']})
Just adjust the options for your need.
Within a sinatra framework, I'm trying to yield a template, dashboard.haml, within a layout template: layout.haml. But when the page loads, a stringified version of the html appears, instead of the HTML itself. So it's clearly fetching the correct template, but I wonder why the html is being rendered as a string??
Here are the relevant code:
server.rb
get '/:developer' do
#workflow_audits = Auditor.new(params['developer']).workflow_audits
haml :dashboard, :layout => :layout
end
views/layout.haml
%html
%head
%title Workflow Stuff
%link{ :rel => :stylesheet, :type => "text/scss", :href => "/stylesheets/dashboard.scss"}
%script{ :src => "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.0/js/bootstrap.min.js" }
%body
%form{action: '/', method: 'post'}
%label{for: 'developer'}Select a developer:
%input{type: 'text', name: 'developer'}
%input{type: 'submit', value: 'submit'}
= yield
views/dashboard.haml
%ul.issue-list
- #workflow_audits.each do |audit|
%li.issue
.issue-container.row
You have an indentation issue in dashboard.haml. I removed the 3 spaces and tabs in your post and put two spaces everywhere, all errors went away and was able to get it working.
%ul.issue-list
- #workflow_audits.each do |audit|
%li.issue
.issue-container.row
I'm having an issue with my Rails application--I'm having trouble sending both a HTML and plaintext version of my email. NOTE: the email does send; however, it's not styled correctly... there is a link to the results below.
It's recommended everywhere that if you want to send HTML you should also send a plain text alternative too. Unfortunately, it appears that I'm doing something wrong, as my application does not allow me to send both HTML and plaintext, without the HTML looking very weird.
here is my mailer model:
class ProjectMembersMailer < ActionMailer::Base
def membership_invitation(membership)
#project = membership.project
#user = membership.user
mail( :subject => %(Invitation to join project #{#project.business_name}),
:from => %("App" <no-reply#appname.com>),
:to => #user.account.email,
:content_type => "text/html" ) do |format|
format.html
format.text
end
end
end
My project_member_mailer views have two files: membership_invitation.html.haml and membership_invitation.text.erb (please note that the second file is using .erb, but even if I convert it to a .haml extension for consistency I get the same error)
Here is picture of that the output looks like when I attempt to send it using the code above. Please note that I removed some of the text.
Basically it looks like it's sending the text version above the html version of the file. Is there an alternate way to sending both plaintext and HTML emails without this happening? Or am I missing something--like, should these emails not be sent simultaneously? Any help would be greatly appreciated. Thank you so much for your time and help!
According to the Action Mailer Rails Guide you do not need to use the "format" method, and should remove the "content-type" parameter too.
mail will automatically detect that there are both html and text templates and will automatically create the email as multipart/alternative
Just try:
mail( :subject => %(Invitation to join project #{#project.business_name}),
:from => %("App" <no-reply#appname.com>),
:to => #user.account.email)
I had the exact same problem, and it can be fixed with just one simple thing. Place format.text over format.html
def membership_invitation(membership)
#project = membership.project
#user = membership.user
mail( :subject => %(Invitation to join project #{#project.business_name}),
:from => %("App" <no-reply#appname.com>),
:to => #user.account.email,
:content_type => "text/html" ) do |format|
format.text
format.html
end
end
i'm having a bit of trouble with adding a certain feature. i'm working on a buy/sell site and i want to be able to compare posts. here's what i have so far:
in the posts view:
<%= button_to "Add to Compare", :action => "addCompare" %>
in the corresponding controller:
##a = Array.new()
def addCompare
##a << Post.id
end
so, all i want to do is add the post's id to the array ##a. when i test this, i click on the "Add to Compare" button and I'm welcomed with this:
Template is missing
Missing template posts/addCompare with {:locale=>[:en, :en], :formats=>[:html], :handlers=>[:rxml, :rjs, :builder, :rhtml, :erb]} in view paths "/home/mja32/470repo/traders/app/views", "/var/lib/gems/1.8/gems/devise-1.4.2/app/views"
So I guess it's trying to redirect to a view. How do I prevent it from doing this? All I want this button to do is to add the post's id to the array and nothing more.
Thanks in advance,
Matt
First of all, storing persistent data in a controller's class variable isn't going to work the way you want it to. There's no guarantee that ##a will be the same array on your next addCompare call; for example, your next addCompare call could be handled by a different process. Also, what happens if two different clients call addCompare? Do you really want to mix their data together in one pile? Probably not. Your first task is to replace ##a with a real per-user persistent store.
If you want to return nothing at all from your controller, just do this at the end of your controller method:
render :nothing => true, :status => :ok
That will tell Rails that something has already been rendered so it doesn't need to try the default rendering action (which is to render the posts/addCompare view) and returns nothing more than a 200 status code to the client.
Once that's in place, you'll probably want to AJAXify your button with :remote => true:
:remote - If set to true, will allow the Unobtrusive JavaScript drivers to control the submit behaviour. By default this behaviour is an ajax submit.
So this:
<%= button_to "Add to Compare", { :action => "addCompare" }, { :remote => true } %>
Note that button_to looks like this:
button_to(name, options = {}, html_options = {})
and that :action is for options but :remote is for html_options so you have to explicitly set up the hashes with {}; you could just wrap the options in braces:
<%= button_to "Add to Compare", { :action => "addCompare" }, :remote => true %>
but I prefer the consistency of wrapping them both by hand.
It's obvious from the documentation (and google) how to generate a link with a segment e.g. podcast/5#comments. You just pass a value for :anchor to link_to.
My concern is about the much simpler task of generating the <a name="comments">Comments</a> tag i.e. the destination of the first link.
I've tried the following, and although they seemed to work, the markup was not what I expected:
link_to "Comments", :name => "comments"
link_to "Comments", :anchor => "comments"
I think I'm missing something obvious. Thanks.
You are getting confused by Ruby's syntactic sugar (which Rails uses profusely). Let me explain this briefly before answering your question.
When a ruby function takes a single parameter that is a hash:
def foo(options)
#options is a hash with parameters inside
end
You can 'forget' to put the parenthesis/brackets, and call it like this:
foo :param => value, :param2 => value
Ruby will fill out the blanks and understand that what you are trying to accomplish is this:
foo({:param => value, :param2 => value})
Now, to your question: link_to takes two optional hashes - one is called options and the other html_options. You can imagine it defined like this (this is an approximation, it is much more complex)
def link_to(name, options, html_options)
...
end
Now, if you invoke it this way:
link_to 'Comments', :name => 'Comments'
Ruby will get a little confused. It will try to "fill out the blanks" for you, but incorrectly:
link_to('Comments', {:name => 'Comments'}, {}) # incorrect
It will think that name => 'Comments' part belongs to options, not to html_options!
You have to help ruby by filling up the blanks yourself. Put all the parenthesis in place and it will behave as expected:
link_to('Comments', {}, {:name => 'Comments'}) # correct
You can actually remove the last set of brackets if you want:
link_to("Comments", {}, :name => "comments") # also correct
In order to use html_options, you must leave the first set of brackets, though. For example, you will need to do this for a link with confirmation message and name:
link_to("Comments", {:confirm => 'Sure?'}, :name => "comments")
Other rails helpers have a similar construction (i.e. form_for, collection_select) so you should learn this technique. In doubt, just add all the parenthesis.
If you want to go through rails, I suggest content_tag (docs).
Example:
content_tag(:a, 'Comments', :name => 'comments')
<%= link_to('new button', action: 'login' , class: "text-center") %>
created an anchor tag for login.html i.g
new button
and for
new button
use
<%= link_to('new button', controller: 'admin',
action: 'login' , class: "text-center") %>
