I'm creating a metro application for a project. I'm attempting to pass a hash containing the options that a user can select as the key and the url it will redirect to as the value. When I do, sinatra reports:
no implicit conversion of Array into String
Which is strange, because I do not have an array so far in my application. I have tried commenting out the embedded ruby in the index.erb file, but that didn't help. The application is as follows:
require "sinatra"
require "sinatra/reloader"
red = {
"Woodley Park" => '/woodley_park',
"Dupont Circle" => '/dupont_circle',
"Farragut North" => '/farragut_north',
"Metro Center" => '/metro_center',
"Union Station" => '/union_station'
}
turquoise = {
"Crystal City" => '/crystal_city',
"Metro Center" => '/metro_center',
"Shaw-Howard" => '/shaw_howard',
"Beltwater" => '/beltwater'
}
orange = {
"Farragut West" => '/farragut_west',
"McPherson" => '/mcpherson',
"Metro Center" => '/metro_center',
"Federal Triangle" => '/federal_triangle',
"Smithsonsian" => '/smithsonsian',
"L'efant Plaza" => '/lefant_planza'
}
lines = {
"Red" => "/red_line",
"Turquoise" => "/turquoise_line",
"Orange" => "/orange_line"
}
get '/' do
#header = "Welcome to the D.C. Metro! Which line will you be starting at?"
#options = lines
end
And the index.erb looks like this. Again, commenting out the relevant lines did not change the results. Thanks in advance!
<h2><%= #header %></h2>
<% #options.each do |name, link| %>
<a href=<%= link %>><%= name %></a>
<% end %>

I want to convert my embedded ruby file to PDF file after clicking on a link using Rails 3.I became able to convert simple html file to PDF file using pdfkit gem.I am explaining my code below.
users_controller.rb:
class UsersController < ApplicationController
def index
end
def download_pdf
#html = render_to_string(:action => "/users/download_pdf.html.erb")
#kit = PDFKit.new('http://google.com')
#kit = PDFKit.new(html)
#send_data(kit.to_pdf, :filename => 'report.pdf', :type => 'application/pdf', :disposition => 'inline')
kit = PDFKit.new("<h1>Hello</h1><p>This is PDF!!!</p>", :page_size => "A4")
send_data(kit.to_pdf, :filename => 'report.pdf', :type => 'application/pdf', :disposition => 'inline')
#file = kit.to_file('my_file_name.pdf')
end
end
In this controller page i did and got success to convert from HTML to PDF.
users/index.html.erb:
<p>
<%= link_to "Download pdf",download_pdf_path(:format => 'pdf') %>
</p>
When user will click on the above "download_pdf" link the download.html.erb will convert to PDF file and it should display as well as download in specified folder.The download.html.erb file is given below.
users/download.html.erb:
<h1>Hello Rails</h1>
The above file should convert into PDF file with proper css .If i have css for this like below.
application.css:
h1{
width:100px;
height:100px;
background-color:red;
}
How can i include this CSS in that PDF file.My other files are given below.
pdfkit.rb:
PDFKit.configure do |config|
#config.wkhtmltopdf =Rails.root.join('bin', 'wkhtmltopdf-i386').to_s
config.wkhtmltopdf='C:/wkhtmltopdf/bin/wkhtmltopdf.exe'
#config.default_options[:ignore_load_errors] = true
end
Please help me to resolve this issue and make this successfully.
By using wicked_pdf gem i am getting the following error.
error:
RuntimeError in UsersController#download_pdf
Error: Failed to execute:

Exit with code 1 due to network error: ContentNotFoundError
check the below code for this gem.
users/users_controller.rb:
class UsersController < ApplicationController
def index
end
def download_pdf
render pdf: 'test',
layout: '/layouts/test',
template: '/users/test',
handlers: [:erb],
formats: [:pdf],
:save_to_file => Rails.root.join('public', "test.pdf")
end
end
wicked_pdf.rb:
WickedPdf.config = {
#:wkhtmltopdf => '/usr/local/bin/wkhtmltopdf',
#:layout => "pdf.html",
:exe_path => 'C:/wkhtmltopdf/bin/wkhtmltopdf.exe'
}
You can include your stylesheets by following:
def download_pdf
kit = PDFKit.new(File.open(Rails.root.join('app', 'views', 'users', 'download.html.erb')))
kit.stylesheets << Rails.root.join("app","assets","application.css")
send_data(kit.to_pdf, :filename => 'report.pdf', :type => 'application/pdf', :disposition => 'inline')
end
I have reviewed a number of solutions from stackoverflow to no avail. I was hoping someone could help me understand the error of my ways.
The haml markup looks like:
.graduation-date-range
%label Graduation Date Range
.row-fluid
.span6
.control-group
.controls
.bfh-selectbox{:id => "graduation_start_year", :style => "width: 100%"}
= f.hidden_field :graduation_start_date
%a.bfh-selectbox-toggle{"data-toggle" => "bfh-selectbox", :href => "#", :role => "button"}
%span.bfh-selectbox-option Start Year
%b.caret
.bfh-selectbox-options
%div{:role => "listbox"}
%ul.start-years{:role => "option"}
- (2012..2018).each do |y|
%li
%a{"data-option" => y, :href => "#"}= y
.help-inline
.span6
.control-group
.controls
.bfh-selectbox{:style => "width: 100%"}
= f.hidden_field :graduation_end_date
%a.bfh-selectbox-toggle{"data-toggle" => "bfh-selectbox", :href => "#", :role => "button"}
%span.bfh-selectbox-option End Year
%b.caret
.bfh-selectbox-options
%div{:role => "listbox"}
%ul.end-years{:role => "option"}
- (2012..2018).each do |y|
%li
%a{"data-option" => y, :href => "#"}= y
.help-inline
The solution I am currently trying to employ:
select('2012', :from => 'graduation_start_year', :visible => false)
I receive :
Capybara::ElementNotFound:
Unable to find select box "graduation_start_year"
My understanding is that either the label, name, or ID can be used to select from but I may be mistaken.
Thank you in advance to those who respond.
It appears that this is not a form select box, but an html list that has been turned into something that resembles a dropdown box via javascript and CSS.
capybara select is looking for <select> and <option> tags. This is going to require a js type test with selenium or poltergeist to test.
For my markdown text i normally do the following on the text content(#user.content):
<%= raw Redcarpet.new(#user.content).to_html.html_safe %>
However i am now using the best_in_place gem like this
<%= best_in_place(#question, :statement, :path => {:controller => "users", :action => "update"}, :type => :textarea) %>
How can i integrate Redcarpet with this? i have tried this:
<%= Redcarpet.new(best_in_place(#question, :statement, :path => {:controller => "users", :action => "update"}, :type => :textarea)).to_html.html_safe %>
however the output is not what is expected. The best_in_place readme seems to point to a way to solve this, but i don't understand it here, under the section titled "Using custom display methods". Can someone explain to me how i can make this work?
I have never used the best_in_place gem, so I don't have tried it out. But from the documentation, you should do the following steps:
Add to the call to best_in_place the additional argument :display_as.
Implement the method referenced by :display_as in your model object.
Here are the details:
Additional argument
%= best_in_place(#question, :statement, :display_as => 'mk_statement', :path => {:controller => "users", :action => "update"}, :type => :textarea) %>
Implementation in the model
class Question
require 'redcarpet'
def mk_statement
Redcarpet.new(self.statement).to_html.html_safe
end
You can also use the display_with attribute and pass it a proc like so:
<%= best_in_place(#question, :statement, :display_with => proc { |v| Redcarpet.new(v).to_html.html_safe, :path => {:controller => "users", :action => "update"}, :type => :textarea) %>
Well I have a two models related with a on-to-many assoc.
#models/outline.rb
class Outline < ActiveRecord::Base
has_many :documents
end
#models/document.rb
class Document < ActiveRecord::Base
belongs_to :outline
end
#admin/outlines.rb
ActiveAdmin.register Outline do
form do |f|
f.inputs "Details" do
f.input :name, :required => true
f.input :pages, :required => true
...
f.buttons
end
f.inputs "Document Versions" do
f.has_many :documents, :name => "Document Versions" do |d|
d.input :file, :as => :file
d.buttons do
d.commit_button :title => "Add new Document Version"
end
end
end
end
end
Well as you can see in the admin/outlines.rb I already tried setting up the :name, in the has_many :documents, and the :title in the commit_button, but neither of that options work, I also tried with :legend, :title, and :label, instead of :name in the .has_many. Not working.
This is the result of that code:
Screenshot
What I want to display is "Document Versions" instead of "Documents", and "Add new Document Version" instead of "Add new Document"
If someone can have a solution it would be great
To set has_many header you can use
f.has_many :images, heading: 'My images' do |i|
i.input :src, label: false
end
See here
Looking at ActiveAdmin tests("should translate the association name in header"), there may be another way of doing this. Use your translation file.
If you look at ActiveAdmin has_many method (yuck!!! 46 lines of sequential code), it uses ActiveModel's human method.
Try adding this to your translation file
en:
activerecord:
models:
document:
one: Document Version
other: Document Versions
One quick hack is that you can hide the h3 tag through its style.
assets/stylesheets/active_admin.css.scss
.has_many {
h3 {
display: none;
}}
This will hide any h3 tag under a has_many class.
You can customise the label of the "Add..." button by using the new_record setting on has_many. For the heading label you can use heading:
f.has_many :documents,
heading: "Document Versions",
new_record: "Add new Document Version" do |d|
d.input :file, :as => :file
end
Sjors answer is actually a perfect start to solving the question. I monkeypatched Active Admin in config/initializers/active_admin.rb with the following:
module ActiveAdmin
class FormBuilder < ::Formtastic::FormBuilder
def titled_has_many(association, options = {}, &block)
options = { :for => association }.merge(options)
options[:class] ||= ""
options[:class] << "inputs has_many_fields"
# Set the Header
header = options[:header] || association.to_s
# Add Delete Links
form_block = proc do |has_many_form|
block.call(has_many_form) + if has_many_form.object.new_record?
template.content_tag :li do
template.link_to I18n.t('active_admin.has_many_delete'), "#", :onclick => "$(this).closest('.has_many_fields').remove(); return false;", :class => "button"
end
else
end
end
content = with_new_form_buffer do
template.content_tag :div, :class => "has_many #{association}" do
form_buffers.last << template.content_tag(:h3, header.titlecase) #using header
inputs options, &form_block
# Capture the ADD JS
js = with_new_form_buffer do
inputs_for_nested_attributes :for => [association, object.class.reflect_on_association(association).klass.new],
:class => "inputs has_many_fields",
:for_options => {
:child_index => "NEW_RECORD"
}, &form_block
end
js = template.escape_javascript(js)
js = template.link_to I18n.t('active_admin.has_many_new', :model => association.to_s.singularize.titlecase), "#", :onclick => "$(this).before('#{js}'.replace(/NEW_RECORD/g, new Date().getTime())); return false;", :class => "button"
form_buffers.last << js.html_safe
end
end
form_buffers.last << content.html_safe
end
end
end
Now in my admin file I call titled_has_many just like has_many but I pass in :header to override the use of the Association as the h3 tag.
f.titled_has_many :association, header: "Display this as the H3" do |app_f|
#stuff here
end
Does not deserve a prize but you could put this in config/initializers/active_admin.rb . It will allow you to tweak the headers you want using a config/locales/your_file.yml (you should create the custom_translations entry yourself). Dont forget to restart the server. And use the f.hacked_has_many in your form builder.
module ActiveAdmin
class FormBuilder < ::Formtastic::FormBuilder
def hacked_has_many(association, options = {}, &block)
options = { :for => association }.merge(options)
options[:class] ||= ""
options[:class] << "inputs has_many_fields"
# Add Delete Links
form_block = proc do |has_many_form|
block.call(has_many_form) + if has_many_form.object.new_record?
template.content_tag :li do
template.link_to I18n.t('active_admin.has_many_delete'), "#", :onclick => "$(this).closest('.has_many_fields').remove(); return false;", :class => "button"
end
else
end
end
content = with_new_form_buffer do
template.content_tag :div, :class => "has_many #{association}" do
# form_buffers.last << template.content_tag(:h3, association.to_s.titlecase)
# CHANGED INTO
form_buffers.last << template.content_tag(:h3, I18n.t('custom_translations.'+association.to_s))
inputs options, &form_block
# Capture the ADD JS
js = with_new_form_buffer do
inputs_for_nested_attributes :for => [association, object.class.reflect_on_association(association).klass.new],
:class => "inputs has_many_fields",
:for_options => {
:child_index => "NEW_RECORD"
}, &form_block
end
js = template.escape_javascript(js)
_model = 'activerecord.models.' + association.to_s.singularize
_translated_model = I18n.t(_model)
js = template.link_to I18n.t('active_admin.has_many_new', :model => _translated_model), "#", :onclick => "$(this).before('#{js}'.replace(/NEW_RECORD/g, new Date().getTime())); return false;", :class => "button"
form_buffers.last << js.html_safe
end
end
form_buffers.last << content.html_safe
end
end
end
If you have issues with locale files not being loaded good in staging/production mode, adding this to your application.rb might help (substitute :nl for the right locale)
config.before_configuration do
I18n.load_path += Dir[Rails.root.join('config','locales','*.{rb,yml}').to_s]
I18n.locale = :nl
I18n.default_locale = :nl
config.i18n.load_path += Dir[Rails.root.join('config','locales','*.{rb,yml}').to_s]
config.i18n.locale = :nl
config.i18n.default_locale = :nl
I18n.reload!
config.i18n.reload!
end
config.i18n.locale = :nl
config.i18n.default_locale = :nl
I'm writing a small Ruby program that will pull records from a database and send an HTML email daily. I'm attempting to use ActionMailer 3.0.3 for this, but I'm running in to issues. All the searching I've done so far on using ActionMailer outside of Rails applies to versions prior to version 3. Could someone point me in the right direction of where to find resources on how to do this? Here's where I am so far on my mailer file:
# lib/bug_mailer.rb
require 'action_mailer'
ActionMailer::Base.delivery_method = :file
class BugMailer < ActionMailer::Base
def daily_email
mail(
:to => "example#mail.com",
:from => "example#mail.com",
:subject => "testing mail"
)
end
end
BugMailer.daily_email.deliver
I'm definitely stuck on where to put my views. Every attempt I've made to tell ActionMailer where my templates are has failed.
I guess I should also ask if there's a different way to go about accomplishing this program. Basically, I'm doing everything from scratch at this point. Obviously what makes Rails awesome is it's convention, so is trying to use parts of Rails on their own a waste of time? Is there a way to get the Rails-like environment without creating a full-blown Rails app?
After some serious debugging, I found how to configure it.
file mailer.rb
require 'action_mailer'
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:domain => "domain.com.ar",
:authentication => :plain,
:user_name => "test#domain.com.ar",
:password => "passw0rd",
:enable_starttls_auto => true
}
ActionMailer::Base.view_paths= File.dirname(__FILE__)
class Mailer < ActionMailer::Base
def daily_email
#var = "var"
mail( :to => "myemail#gmail.com",
:from => "test#domain.com.ar",
:subject => "testing mail") do |format|
format.text
format.html
end
end
end
email = Mailer.daily_email
puts email
email.deliver
file mailer/daily_email.html.erb
<p>this is an html email</p>
<p> and this is a variable <%= #var %> </p>
file mailer/daily_email.text.erb
this is a text email
and this is a variable <%= #var %>
Nice question! It helped me to understand a bit more how Rails 3 works :)
It took me a while to get this to work in (non-)Rails 4. I suspect it's just because I have ':require => false' all over my Gemfile, but I needed to add the following to make it work:
require 'action_view/record_identifier'
require 'action_view/helpers'
require 'action_mailer'
Without the above code, I kept getting a NoMethodError with undefined method 'assign_controller'.
After that, I configured ActionMailer as follows:
ActionMailer::Base.smtp_settings = {
address: 'localhost', port: '25', authentication: :plain
}
ActionMailer::Base.default from: 'noreply#example.com'
ActionMailer::Base.raise_delivery_errors = true
ActionMailer::Base.logger = Logger.new(STDOUT)
ActionMailer::Base.logger.level = Logger::DEBUG
ActionMailer::Base.view_paths = [
File.join(File.expand_path("../../", __FILE__), 'views', 'mailers')
# Note that this is an Array
]
The templates go in lib/<GEM_NAME>/views/mailers/<MAILER_CLASS_NAME>/<MAILER_ACTION_NAME>.erb (MAILER_ACTION_NAME is the public instance method of your mailer class that you call to send the email).
Lastly, don't forget to put this in your spec_helper:
ActionMailer::Base.delivery_method = :test
