I'm sending an email using Rails like this:
attachments["ticket.pdf"] = WickedPdf.new.pdf_from_string(render_to_body(pdf: "ticket", template: 'template' }))
This works well in Gmail but in several other clients the attached pdf just doesn't appear.
Looking at the source code I realized it's a problem with mimeparts.
I'm having a hard time making an attachment file show in yahoo and several other email clients such as Thunderbird, if I analize the source code of the email sent I discover this:
The mimepart is the same for each part of the file...
the hierarchy (as far as i understand) must be like this:
multipart/mixed
multipart/alternative
multipart/related
text/html
image/png (e.g. for an inline attachment; pdf would be another good example)
text/plain
application/zip (e.g for an attachment--not inline)
This i extracted from https://github.com/jcoleman/mail_alternatives_with_attachments
Here, is the email source (just chunks of the content for better understanding):

All of your mimepart boundaries are the same...they're all the 'alternative' boundary.
--==_mimepart_5065e7f4af345_a9e43fdbdd45a760153b9
For an email with HTML, plain text AND attachments, you need to declare and properly encapsulate the separate parts by properly putting the boundaries in their right places. The easiest way to get a grasp of what that looks like is to manually create an email in an email client with all the 'features' you want (HTML + plain text + attachments) and then view the source and take note of how the mimepart boundaries are laid out.
Each "part" of the email source actually declares what the boundary looks like, and then at the end of each part there are one or more of those boundary lines indicating the end of the part. Parts can and should be encapsulated within other parts. It's damn complicated but the take-home note is that in your example, you only have one mimepart declared and used when you should have more (as you indicated in your hierarchy).
Now as for where/when this goes awry, we'd have to see the code you're using to generate the email from start to finish.

Question is: how do I get the full products to show on the webpage so I can start scraping if it has a referer link and it does not automatically gets the products. [This][2] is the resulting HTML:
I give 2 solutions, but only one uses a POST as you requested in your question:
require 'mechanize'
agent = Mechanize.new
agent.get("http://www.sistemasaplicados.com.mx/")
agent.page.forms.first.field_with(name: "buscar").value = ' '
result_page = agent.page.forms.first.submit
The other option is to encode your search term and use it in a simple the GET request (encoded in the URL) directly with nokogiri. In your particular case a search for "160GB" leads to following URL http://www.sistemasaplicados.com.mx/articulos.php?buscar=160GB, which you can just GET.
Btw, you do not necessarily need mechanize for all that, except you want to place orders into your account automatically or something like that. I assume you do that in the interest of sistemasaplicados otherwise I would consider this rude and it would bring you bad karma.
Update
When manually checking what is happening you should look what happens if JavaScript is disabled (in this case, there are no results). Then, with the "inspector", "console" or "developer tools" of your Browser (often opened by pressing F12) find out what happens. In your case a POST request to resultados.php is done. I found out with firefox, dev tools, "Network" tab. There also you find the relevant parameters to fire up in your POST request.
I tried running the test script on script.google.com ( https://developers.google.com/gmail/schemas/apps-script-tutorial ), and while the email sent, the action button wasn't enabled.
I'm wondering if this is because I am logged in as a google apps user (me#mydomain.com). I see SPF pass and DKIM in the mail headers, and I do see other action buttons in my google apps gmail.

Google Apps domain get updates on a different schedule than Gmail users and actually the domain administrators can choose to be on the Scheduled Release Track or the Rapid Release Track for updates:
http://whatsnew.googleapps.com/release-tracks
I guess your domain is on the Scheduled Release Track and the support for Actions hasn't rolled out yet.
I have a simple out of the box rails server running and I am trying to figure out how to make it work with the If-Modified-Since header. I am using the following curl request.
curl -I localhost:3000/shows/1 --header 'If-Modified-Since: Thu, 21 Jun 2012 19:16:20 GMT'
I always get 200 OK but I want 304 Not Modified.
When I do this through the browser I get a 304 Not Modified but not with curl.
Am I doing it wrong?
UPDATE
If I run
curl -v -I localhost:3000/shows/1 --header 'If-Modified-Since: Thu, 21 Jun 2012 19:16:20 GMT'
I get:
* About to connect() to localhost port 3000 (#0)

You need to use the stale? method to tell Rails that you want to use if-modified-then
You're actually calling the show method. Change it to be:
def show
#show = Show.find(params[:id])
if stale?(:etag => #show, :last_modified => #show.updated_at.utc)
respond_to do |format|
format.html # index.html.erb
format.json { render json: #show }
end
end
end
Starting with no cache on server or client
FIRST REQUEST
GET /post/1 HTTP/1.1
HTTP/1.1 200 OK
Date: Fri, 05 Mar 2010 09:05:46 GMT
Last-Modified: Thu, 04 Mar 2010 21:00:08 GMT
X-Rack-Cache: miss
Etag: "c226165d5817af7c91592dab0bc0ac63"
Cache-Control: max-age=3600, public
The Cache is missed and Rails gets hit and queries the database:
if stale?(:etag => #document, :last_modified => #document.updated_at.utc) # => true
expires_in 1.hour, :public => true
#post = Post.find(params[:id])
end
SECOND REQUEST
GET /post/1 HTTP/1.1
If-Modified-Since: Thu, 04 Mar 2010 21:00:08 GMT
If-None-Match: "c226165d5817af7c91592dab0bc0ac63"
Cache-Control: max-age=0
HTTP/1.1 304 Not Modified
Date: Fri, 05 Mar 2010 09:10:04 GMT
X-Rack-Cache: miss
Etag: "c226165d5817af7c91592dab0bc0ac63"
Cache-Control: max-age=3600, public
The Cache is missed and Rails gets hit, but this time it sends 304 Not Modified and the database is not hit:
if stale?(:etag => #document, :last_modified => #document.updated_at.utc) # => false
expires_in 1.hour, :public => true
#post = Post.find(params[:id])
end
However I was under the impression this should hit the Cache since the etag matches (If-None-Match/Etag)?
I'm doing a full refresh (F5) so the browser is adding Cache-Control: max-age=0 which is preventing the cache thinking the page is fresh.
It's my understanding that the If-None-Match and If-Modified-Since headers are sent when the browser's cached content expires (the content has been in the browser's cache for more than the maxage in the Cache-Control header). This allows your application to verify that the content is still fresh and if it is, then send the 304 with a new maxage and the same Etag as before.
