    <p>I want to implement a real simpel newsletter. Therefor I can select as much recipients I want.</p> <p>To that newsletter I can attach a file. This works great for the first mail. All next mails have corrupted attachments (1 byte size).</p> <p>actionmailer:</p> <pre><code>def send_newsletter(recipient,subject,content,file) @content = content if file attachments[file.original_filename] = { :content=&gt; file.read, :mime_type=&gt; file.content_type } end mail(:to =&gt; recipient, :template_name =&gt; "deliver_newsletter", :subject =&gt; subject).deliver! end </code></pre> <p>applicationcontroller:</p> <pre><code> def create @customers = Customer.where("CHAR_LENGTH(email) &gt; 0") @recipients = params[:sent_to] @subject = params[:subject] @content = params[:content].html_safe @file = params[:file] if @recipients @recipients.each do |mail_recipient| Newsletter.send_newsletter(mail_recipient,@subject,@content,@file) end end respond_to do |format| format.html { redirect_to bills_path, notice: "everything works fine" } end end </code></pre> <p>and finally the form for sending newsletters:</p> <pre><code> &lt;%= form_tag ('/newsletters'), :multipart =&gt; true do %&gt; &lt;%= t 'views.newsletter.to_recipient' %&gt;:&lt;br&gt; &lt;%= select_tag 'sent_to', options_from_collection_for_select(@customers, 'email', 'name'), :multiple =&gt; true, :class =&gt; 'sent_to' %&gt;&lt;br&gt;&lt;br&gt; &lt;%= t 'views.newsletter.subject' %&gt;:&lt;br&gt; &lt;%= text_field_tag 'subject' %&gt;&lt;br&gt;&lt;br&gt; &lt;%= t 'views.newsletter.content' %&gt;:&lt;br&gt; &lt;%= text_area_tag 'content', "".html_safe, :size=&gt;"20x8" %&gt;&lt;br&gt;&lt;br&gt; &lt;%= t 'views.newsletter.attachment' %&gt;:&lt;br&gt; &lt;%= file_field_tag 'file' %&gt;&lt;br&gt;&lt;br&gt; &lt;%= submit_tag t('views.buttons.newsletter_send_now'), :class =&gt; "btn btn-primary", :disable_with =&gt; t('views.buttons.newsletter_sending') %&gt; &lt;% end %&gt; </code></pre> <p>another small question: why is "delay" from the "delay_jobs" gem not working here? All other mails can be sent by typing "Newsletter.delay.send_newsletter(...)"</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
