<% consents_checkboxes.each do |checkbox| %>
<%= checkbox.html_safe %>
<% end %>
Hello there,
can i give them a class while looping through them? I can't get it to work and tried several different ways.
This is something I would like to achieve
<% consents_checkboxes.each do |checkbox| %>
<%= checkbox.html_safe, class: 'checkbox' %>
<% end %>
thank you
You can only do it with an element. What you want to do is:
<% consents_checkboxes.each do |checkbox| %>
<p class="checkbox"><%= checkbox.html_safe %></p>
<% end %>
Of course, you can use another element (span, div etc.).
What's on consents_checkboxes? You should provide more context when you ask for something...
It looks like you have strings with the html code, right? you will have to parse the string with something like nokogiri and add a class
<%= Nokogiri.parse(checkbox).add_class('checkbox') -%>
Or you could modify the process that generates that consents_checkboxes to include the class you need. Maybe there's better options, but with only that information it's really hard to tell.

I am trying to underline words that are dynamically generated by the debug(params) method provided by rails. I have something below, but it obviously does not work, plus what I have below is attempt to try and change the words using methods that I already know about (like the .upcase method). I was hoping to underline the word controller if it appears in the text using only Ruby. Can anyone help me out here?
<%= debug(params) if Rails.env.development? %>
<% if debug(params).include?('controller:') %>
<%= 'controller'.upcase %>
<% end %>
thanks
edit:
I should add that debug(params) is a method defined by RAILS, I was able to do the following which seems even more off, so far the answers have not been correct to what I want to do.
<% if Rails.env.development? %>
<% debug_method = debug(params).split.each do |word| %>
<% if word == 'controller:' %>
<ul><% word.upcase %></ul>
<% end %>
<% end %>
<%= debug_method.join %>
<% end %>
which returns the following text: https://ibb.co/cvnEpw , keep the answers coming in though. I want to get the words in the original box (that's generated by the method to underline the controller word https://ibb.co/jmSm2G).
use <u></u> tag
<%= debug(params) if Rails.env.development? %>
<% if debug(params).include?('controller:') %>
<u><%= 'controller'.upcase %></u>
<% end %>
example here
Provide the css to generate html element:
p { text-decoration: underline; }
Add html elemnt to wrap your words:
<%= debug(params) if Rails.env.development? %>
<% if debug(params).include?('controller:') %>
<p> <%= 'controller'.upcase %> </p>
<% end %>
The answer to the question is below. I had to use the .gsub and .html_safe methods.
<%= debug(params).gsub("controller:", "<u>controller:</u>").html_safe %>
This code keeps the existing html & css generated by rails intact
I'm a little new to back-end programming...I'm currently running the following code in my rails 4 app to show a basic list of all the admins on a project (if there are any)...
<% if project.projectadmins.any? %>
<div class="row-fluid">
<% project.projectadmins.each do |user| %>
<div class="collaborator">
<%= link_to user do %>
<%= image_tag user.image_url(:thumb).to_s, :class => "profile-pic-thumb" %>
<% end %>
</div>
<% end %>
</div>
<% end %>
However, I also have projectcollaborators for each project, so I'd like to know what the most effective way would be to combine those and provide a list of both projectadmins AND projectcollaborators (with project admins being listed first if there are any...other than that ordering is not important).
I assume the if statement at the beginning would change to...
<% if project.projectadmins.any? || project.projectcollaborators.any? %>
but I'm not 100% sure and am lost on the rest...any help is much appreciated.
You could create a scope, for example project_admins_and_collaborators, which gets all the needed records and then use it in your loop.
You can also do this in following way
project_admins_and_collaborators = project.projectadmins
project_admins_and_collaborators << project.projectcollaborators
project_admins_and_collaborators.flatten.uniq do |user|
#your code
end
In the Rails views, I regularly find lines like:
<%= my_var %>
What if I had a slightly more complex situation and I needed to trigger the printing with plain code instead of <%= %>?
Example:
<% .....
puts my_var
%>
I guess is a silly question but bear with me, I'm a ruby beginner.
Look at documentation of ERB
In <% %> you put expressions that are not for printing out.
In <%= %> you put code for printing out.
Example:
<% if #cost < 10 %>
<b>Only <%= #cost %>!!!</b>
<% else %>
Call for a price, today!
<% end %>
You can use helper method which is much more cleaner.
How can I condense my code into a single statement:
<% #policyholderdetail.errors.each do |attr,msg| %>
<% if attr == :title %>
<li><%=attr %> <%= msg %></li>
<% end %>
<% end %>
I would like to show only the errors for :title next to the field but feel there should be a better statement to do this as opposed to looping through all of the errors until I get to the one I want.
Question - can I condense the first two lines into one better statement?
You can write: #policyholderdetail.errors[:title]. See here.
Use
<% if #policyholderdetail.errors[:title].present? %>
I'm using Ruby on Rails and need to run a block of Ruby code in one of my html.erb files. Do I do it like this:
<% def name %>
<% name = username %>
<%= name %>
or like this:
<% def name
name = username %>
<%= name %>
Thanks for reading.
If you need extra functions in your view, you normally declare those inside a helper.
For each controller, if there is a helper it is automatically loaded. For instance, if you have a PeopleController, in the app/helpers folder, there should be a people_helper.rb, and it should look like this
module PeopleHelper
def name
#do something
username
end
end
Another, very clean alternative, is to use the Presenter pattern, but i think it is less common (unfortunately).
Otherwise, if you do need multiple lines of ruby code inside a erb view, which i try to avoid, i prefer the following style:
<%
counter_1 = 0
counter_2 = 1
do_some_more_prep_here
%>
<% #records.each do |rec|%>
<%# do something with the prepped date in each row %>
<% end %>
Also for me code indentation is more important than html indentation, so i will prefer something like
<table>
<% #rows.each do |row| %>
<tr>
<td><%= row.item1 %></td>
<% if row.some_test %>
<td><%= row.item2 %></td>
<% end %>
</tr>
<% end %>
</table>
But i am always very interested to hear different opinions in this matter.
It is unusual to define a method in an ERB file, so I recommend against it.
If you want to call a block like #each, you can do something like the following:
<% names.each do |name| %>
<%= name %>
<% end %>
Don't forget the <% end %>.
I can imagine someone needing it in one particular template (no point in creating a helper) to not duplicate html markup. That is, when resulting html page has a couple of similar blocks of html markup. Though, it can easily be abused (unreadable code).
<% def f1(a, b, c) %>
test: <%= a %>, <%= b %>, <%= c %>
<% end %>
<% f1(1, 2, 3) %>
<% f1(4, 5, 6) %>
